we have specially summarized the following failures that will occur when using grouting pipes. If you have problems in the following examples, you will know how to solve them The first point is that if the joint, nozzle or bottom of the grouting pipe is not tightly sealed,CanadaAdvance small conduit in tunnel construction, it will be blocked by cement slurry during construction. At this time, it is OK to check the sealing The second point is that the joint is misaligned or deformed during installation. At this time, we need to know that it is caused by the thin material selected. The above two points are common problems in the installation of grouting pipes that are not suitable for the current location. We&#;d better remember these points of attention, so that when they occur in the future, we will know how to deal with them to ensure a quick solution! The grouting pipe joint or the pipe orifice and the pipe bottom are not sealed tightly, so please bring in mud or cement slurry during the construction process to block the pipe: during the installation and grouting of the grouting pipe the rebar is distorted or collided, causing the dislocation and deformation of the grouting pipe joint or the deformation of the pipe wall. The main reason for this is the selection of thin-walled grouting pipes.Can the stretching speed of grouting pipe be defined?Canada,During high-pressure grouting, the water stop needle is used from top to bottom along the crack at an angle of degrees, about cm to the left and right. The straight-line distance between the two water stop needles is about cm. If the crack is too large, it can be directly drilled vertically to the crack.The grouting pipe without shaft roll packaging is tapped and paid off from the inner ring in the vertical state, and the drawn out pipe is spring shaped and automatically straightened. Takeout direction: the spiral direction of the spring shape after takeout is consistent with the twisting direction of, otherwise fried dough twist or disorder will occur. Welding is strictly prohibited during use, because the strength of the welding point is much lower than that of the steel itself, and it is easy to cause broken wires at the welding point during tensioning. When the grouting pipe adopts circular reinforcement arrangement, its bending radius shall not be less than times of the diameter.Butwal,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, so it is impossible to comprehensively test the whole pile and judge the quality of the pile foundation! The grouting pipe is used as the pipe for grouting at the bottom of the pile. The test shows that the bearing capacity of the cast-in-place pile treated with the pile bottom grouting can be greatly improved At the same time, it is necessary to take measures to punch the pipe at the defect position where grouting is required. The classification of the grouting pipe can be divided into three categories according to the pipe materials: the advantages of steel pipe steel pipe are that it is easy to install, and it can be welded on the reinforcement frame by electric welding, which can replace part of the reinforcement section, and because of the large rigidity of the steel pipe After embedding, the parallelism and straightness can be basically maintained. At present, many large-diameter cast-in-place piles use steel as the grouting pipe. However, the price of steel pipe is relatively expensive: steel corrugated pipe steel corrugated pipe is a better grouting pipe material. It has the characteristics of thin pipe wall, less steel, impermeability, pressure resistance, high strength and good flexibility. It is usually used for post tensioning reserved holes in prestressed structures: when used as grouting pipe. It can be directly bound to the reinforcement framework soil, and the joint can be connected with a larger corrugated sleeve. Since the bellows is light, it is very convenient to operate, but attention should be paid to keeping its axis straight during installation.The main elastic element of the grouting pipe is the stainless steel grouting pipe, which compensates the axial, lateral and angular direction of the pipe by the expansion and bending of the grouting pipe.

It has good air tightness, low gas permeability strong sealing and no leakage.Construction Engineering Investigate the characteristics of surrounding rock, and determine the grouting range of surrounding rock. Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.Honesty and mutual benefit,Disposal method: the grouting pipe shall be shortened according to the specification.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.?Before the installation of the grouting pipe, The grouting pipe is padded with the front lip of the horseshoe, and the height of the saddle shaped curved surface is changed to make the pipe wall crawl and slide along the accurate saddle shaped curved surface.[patent attachment] [description] [] is the structural diagram of the utility model; [] is a schematic diagram of the cutting blade; [] is the schematic diagram of tightening the blade nut; [] is a schematic diagram of the fixed cutting device.However, not all grouting pipe products can achieve this effect. Some inferior grouting pipe products not only fail to achieve the expected effect in use, but also have problems such as low grouting efficiency, which seriously affect the grouting effect of the grouting pipe and the progress of the whole project. The quality of grouting effect comes from the selection of high-quality grouting pipe products. Shengpeng grouting pipe is a good choice for you to choose grouting pipe products because of its high strength, awesome, simple connection and high cost performance! Grouting pipe the grouting pipe is a kind of geosynthetic material formed by ultrasonic welding which is composed of a steel plastic composite reinforced belt (built-in high-strength carbon spring steel wire (stress material) and wrapped with polyethylene resin (protective material) and arranged at right angles to the plane longitude and latitude. It is a comprehensive product of existing rigid reinforcement (flat steel strip, ribbed steel strip, galvanized steel strip, stainless steel strip, reinforced concrete strip, etc.) and flexible reinforcement (polypropylene strip, plastic grouting pipe, warp knitted grouting pipe, etc.). Because of its high tensile strength, low elongation (≤ %), small creep, and strong interlocking and occlusive effect on the soil, it can effectively treat the soft soil foundation, restrict the lateral displacement of the soil,CanadaPrice of advanced small conduit, overcome the uneven settlement of the soil, greatly enhance the bearing capacity of the foundation and improve the overall performance of the foundation; It can be widely used in road engineering, railway engineering, retaining structure, dam engineering, water conservancy engineering and tunnel engineering; It has remarkable safeguard effect and good social and economic benefits against rutting and pavement cracking.Canada,In recent years, such as mountain slides, floods, earthquakes fires, etc. we are so small in the face of natural disasters that we can only devote our efforts to normal prevention and post disaster rescue. The grouting pipe can reduce the damage caused by these natural disasters.Grouting pipe is an expert in road construction. It can connect the subgrade as a whole and improve the bearing capacity of the subgrade. When encountering natural disasters, the subgrade will not be greatly damaged due to natural disasters, so that we can save more people in the rescue work. The grouting pipe can also play a great role in slope protection. The use of the grouting pipe can well prevent the landslide of mountain soil and debris flow disasters. Through many years of practical experience, it has been proved that the roads that usually use the grouting pipe are far more than the same period of projects in terms of service life and quality. Thus reducing the casualty rate.

Grouting pipe laying and fixing of grouting pipe laying of glass fiber grouting pipe can be carried out by special equipment refitted from tractors or automobiles, or manually.Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.Answer: according to the length and diameter, the weight of common grouting pipe is . ~ .KG, and the weight can reach several kilograms.Application scope and development space of grouting pipe as a new term, grouting pipe has gradually appeared in some online newspapers and periodicals, and its practical scope has also developed from the support of some basic automobile boot and engine cover to the machinery manufacturing industry, used for the support of equipment accessories, vibration reduction of equipment, support of tool box cover medical industry, fitness equipment and other fields. As its practicality is further recognized, its scope of application is becoming wider and wider. Some people in the industry asked: the application range of grouting pipe is becoming wider and wider. Does it have an impact on the original telescopic spring? In my personal opinion, it will not impact the original spring. Of course, it will have a certain impact, because most of the grouting pipes are innovations in the product design of some enterprises. For example, the grouting pipe is very light, convenient and labor-saving. Some units do not know it, so its design has certain limitations, However, enterprises must be innovative in order to be ahead of their peers. We have been making grouting pipes for many years. Experience tells us that many manufacturers are now trying our grouting pipes, and they have been officially used, with obvious effects. However, some enterprises do not know what the grouting pipes are, let alone their s, so they will be in a passive position. Therefore, we hope that some industries, such as machinery manufacturing, automobile and motorcycle, transportation equipment, box manufacturing such as tool boxes medical treatment, fitness kitchen cabinets, etc, If you need to know the and use of the grouting pipe, please feel free to consult me, and I will give you advice
