MakoHollow self-propelled anchor rod manufacturerLet’s take you to understand the performance characteristics and application scope

The stability of the grouting pipe is one of the important factors to control the stability of the whole foundation pit. Its erection must be accurate and in place, and prestress must be applied in strict accordance with the design requirements. In particular, attention should be paid to the stability of the diagonal bracing. During the diagonal bracing operation, every link of the installation must be carefully operated. At the same time, the steel purlin must also ensure its stability, strength and deformation requirements during the production and installation process. In addition, During the whole construction process from foundation pit grouting pipe erection to removal, the grouting pipe must be strictly monitored to ensure its stability. How to improve the bearing capacity of piles with grouting pipes in bored piles, during the drilling process of large-diameter cast-in-place piles, the soil layer around the piles will become loose due to the agitation of the turning heads. In addition, the water immersion makes the soil layer that has started to loosen more loose. This problem can be effectively solved by grouting with grouting pipes. How to improve the bearing capacity of piles when grouting with grouting pipes?When the pipe cannot be connected due to serious blockage, the following treatment principles must be followed: when it is the first pile of a certain bridge, core drilling detection must be carried out; when it is not the first pile of a certain bridge, the construction unit shall apply for changing the detection method The low strain reflection wave method or high strain strain strain measurement method shall be used and signed by the supervisor&#;s representative and the person in charge of quality supervision before implementation; In case of pipe blockage of a bridge for many times, core drilling inspection shall be carried out in due time. Other uses of grouting pipe introduction the grouting pipe of pile foundation refers to the steel pipe that needs to be embedded when testing the quality of pile foundation. Generally, it is bound in the reinforcement cage and lowered into the hole together with the reinforcement cage before pouring concrete! There are many reasons for the grouting pipe to gamble on the pipe, most of which are due to the leakage of slurry caused by the pipe joint not being welded well during processing, and also due to the pipe mouth not being closed well and falling debris, the pipe is blocked! To put it bluntly, the pipe is blocked by sundries! The role of the grouting pipe is to inject clean water into the grouting pipe and put the transducer into the grouting pipe for testing when the integrity of the pile foundation is tested by ultrasonic wave. If the grouting pipe is blocked, the transducer can not be put in, or can not be placed at the bottom of the pile,MakoHollow self-propelled anchor rod manufacturer,Mako25hollow grouting anchor bolt manufacturer, so it is impossible to comprehensively test the whole pile and judge the quality of the pile foundation!Mako, and when abnormalities are found, it is encrypted to cm.The Xiaobian of prestressed machines and tools reminds us that there are many forms of grouting pipes, which can be distinguished from different angles, including the following. According to the type of reinforcement of the grouting pipe, it can be divided into the grouting pipe of thick reinforcement of the grouting pipe, the grouting pipe of parallel reinforcement (wire) bundle of the grouting pipe, and the grouting pipe of steel strand bundle of the grouting pipe. For thick reinforcement, one grouting pipe is generally used to anchor one reinforcement. For tendons and steel strands, a grouting pipe must anchor several steel bars or steel strands at the same time, which are often arranged in a ring or circle, or in a rectangle. Obviously, due to the different number and arrangement of prestressed reinforcement the form and structure of grouting pipe will also be different. According to the principle of grouting pipe and transmitting pretension, it can be divided into grouting pipe relying on bearing pressure, grouting pipe relying on friction and grouting pipe relying on adhesion.Semenyih,Among the many imported projects, the development of the production technology of automobile door and window sealing strips is the most representative. Through the introduction of sealing strip production lines from Japan, Germany, Italy, Britain and other countries, up to now, domestic manufacturers have introduced more than sealing strip production lines. In addition to pure rubber sealing strips, sealing strips of various composite structures, metal skeleton and various rubber composite sealing strips rubber and plastic composite sealing strips can be produced. At present, the overall level of China&#;s sealing strip production technology has basically reached the level of foreign countries in the s, and has become a grouting pipe. Because some projects are not easy to detect when they are manufactured, and the quality of the grouting pipe as a channel for testing instruments has become crucial. If the quality of the grouting pipe is poor, it will bring many hidden dangers. Steel grouting pipe material, which has the characteristics of thin pipe wall, steel saving, impermeability, pressure resistance and high strength, is generally used for post tensioned reserved holes in prestressed structures. When the grouting pipe is used, it can be directly bound to the reinforcement framework. Because the grouting pipe is very light, attention should be paid to the balance of its axis during installation.If any crack is found, it shall be repaired in time otherwise, when the joint is deformed and subjected to water pressure, the ability of the grouting pipe to resist external forces will be greatly reduced. When positioning the grouting pipe, and the grouting pipe must not be allowed to roll or kink. If it is found that there is no twist, it should be adjusted in time. When casting and fixing the grouting pipe, the deviation of the grouting pipe shall be prevented, so as not to shorten one side and affect the water stop effect. When pouring and tamping the concrete, it must be vibrated sufficiently to prevent the poor combination of the grouting pipe and the concrete from affecting the water stop effect. The grouting pipe joint must be well bonded. If the construction site conditions are available, the method of hot vulcanization connection can be used.?They shall be connected as a whole in the factory as far as possible. If it is necessary to connect on site due to manufacturing process, transportation conditions, etc., hot press vulcanization (grouting pipe) or welding (plastic grouting pipe) shall be used. The joint appearance shall be smooth and smooth, and the tensile strength shall not be less than % of the base metal. The so-called 'overlapping' without any treatment is absolutely not allowed. All kinds of cross connection points of grouting pipes shall be made of accessories produced by our new rubber products factory, so as to ensure that on-site connection is only carried out in straight sections during construction. Flexible material with sufficient deformation capacity and good adhesion with concrete.

When the pipe cannot be connected due to serious blockage, the following treatment principles must be followed: when it is the first pile of a certain bridge, core drilling detection must be carried out; when it is not the first pile of a certain bridge, the construction unit shall apply for changing the detection method The low strain reflection wave method or high strain strain strain measurement method shall be used and signed by the supervisor&#;s representative and the person in charge of quality supervision before implementation; In case of pipe blockage of a bridge for many times, core drilling inspection shall be carried out in due time. Common problems and answers of grouting pipe what is the pressure inside the grouting pipe?Reusable grouting pipe product specification: inner diameter: mm; Outer diameter: mm; Inner diameter tolerance: ± .mm; Length of each roll: m.Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.agent,It is necessary to comprehensively consider the selection and configuration of grouting pipes, because there are many types of expansion joints, and correct selection is very important. Only in this way can the design of the piping system be safe, reasonable, reliable and economical.?The grouting pipe can be divided into unconstrained grouting pipe and constrained grouting pipe according to whether it can absorb the pressure thrust (blind plate force) generated by the medium pressure in the pipe; According to the displacement type of the grouting pipe, it can be divided into axial grouting pipe, transverse grouting pipe, angular grouting pipe and pressure balance grouting pipe. The grouting pipe cannot bear load and should be hoisted separately; In addition to the pre deformation required by the design for pre stretching or cold tightening, it is forbidden to adjust the installation deviation of the pipeline by deforming the grouting pipe; During installation, welding slag is not allowed to splash onto the surface of grouting pipe and suffer other mechanical damage; All movable components of the grouting pipe shall not be jammed by external components or restrict the normal operation of its movable parts. Most of the failure of the grouting pipe is caused by the external environment corrosion. Therefore, the contact between the external corrosion medium and the grouting pipe can be considered. For example, for the external pressure axial grouting pipe, a packing sealing device can be added between the outlet end ring and the outlet pipe, which is equivalent to the sleeve grouting pipe. It can not only resist the invasion of external corrosive media, but also add a safety barrier to the grouting pipe. Even if the grouting pipe is damaged, the grouting pipe can also play a compensation role and avoid the failure of the grouting pipe. The use of grouting pipes has been indispensable in modern building construction. In the s, but they were fastener grouting pipes. In the s, China began to develop advanced grouting pipes with multiple s. With the continuous development of China&#;s construction industry in modern times, the construction industry has become increasingly mature and perfect in China, and the bamboo wood grouting pipe has been eliminated by the market. Grouting pipe has become the mainstream form of grouting pipe and is more widely used in construction.Answer: Yes, the elastic extension speed of the grouting pipe can be defined within a certain range in the design, but for a grouting pipe that has been designed,MakoPile bottom grouting pipe, its elastic extension speed is certain.

Low cost, fast time, no loss, free from climate and place constraints.Marketing Department, because the space in the grouting pipe restricts the lateral sliding and rolling of the soil particles inside, the relative displacement trend or relative displacement also occurs between this part of soil particles and adjacent soil particles resulting in friction. This friction force is generally called 'bite force' or 'lateral force resistance'. The 'surface friction' and 'bite force' make the slip and roll of soil particles under the force of the upper limit line at the location of the grouting pipe, and limit the lateral displacement of soil in the whole plane of the grouting pipe. The grouting pipe plays an important role in the key points of settlement. Therefore it is reasonable to use the grouting pipe to treat the uneven settlement of fill excavation transition subgrade. This paper yzes the action mechanism of the grouting pipe according to its type and characteristics, and proposes a new technology of sprinkling a layer of filler in the grouting pipe network when paving the surface course. As a kind of road reinforcement material, grouting pipe is widely used in road maintenance engineering because of its advantages of simple, fast construction and low investment. specification: inner diameter of disposable grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: ± .mm; Length of each roll: m. Inner diameter of repetitive grouting pipe: mm; Outer diameter: mm Inner diameter tolerance: ± .mm; Length of each roll: m.The existence of grouting pipe mesh restricts the lateral movement of soil. The lateral sliding deformation of the soil is limited by friction and interlocking engagement between the grouting pipe and the sand particles and the passive resistance of the sand particles to the grouting pipe, forming a good interlocking effect, so that the soil has better overall shear strength and bending stiffness.Mako, The small editor of the grouting pipe reminds everyone that there should be no rust, water and other impurities when using the prestressed machinery. The working clip can be used after removing the foam in the packing box, and the grouting pipe should be properly kept. However, when the prestressed tendon is long and the grouting pipe needs to be tensioned repeatedly, it is suggested that a small amount of lubricant (e.g. anchor pulling spirit) be applied to the tapered hole of the anchor plate by the prestressed machine, which is not only conducive to the follow-up and anchor pulling of the working clip, but also conducive to the multiple grouting of the grouting pipe; Apply lubricant on the outer surface of the tool clip and the inner and outer surfaces of the taper hole of the anchor plate before use, and regularly remove the debris on the clip surface to make the anchor flexible. However, when the clip is cracked or the tooth surface is damaged, it needs to be replaced and can not be used again. It has good air tightness, low gas permeability, strong sealing and no leakage.When the pipe cannot be connected due to serious blockage the following treatment principles must be followed: when it is the first pile of a certain bridge, core drilling detection must be carried out; when it is not the first pile of a certain bridge the construction unit shall apply for changing the detection method The low strain reflection wave method or high strain strain strain measurement method shall be used and signed by the supervisor&#;s representative and the person in charge of quality supervision before implementation; In case of pipe blockage of a bridge for many times, core drilling inspection shall be carried out in due time.
