and then punched with regular holes. Then it is made by directional stretching under the control of heating. It can be divided into unidirectional grouting pipe and bidirectional grouting pipe according to the different stretching modes when it is manufactured. Grouting pipe at tensioning end: the grouting pipe installed at the end of the grouting pipe reinforcement and capable of tensioning is also called grouting pipe grouting pipe. The so-called grouting pipe is a grouting pipe in post tensioning structure or component to maintain the tension of the grouting pipe reinforcement and transmit it to the mixed tension; Fixed end grouting pipe: a grouting pipe installed at the end of the grouting pipe reinforcement and usually buried in the concrete without tensioning. The standard of the grouting pipe used for the grouting pipe reinforcement is the national standard of the people&#;s Republic of China (GB / T -, which ensures that the products manufactured by our company conform to the product quality law of the people&#;s Republic of China and the standard law of the people&#;s Republic of China Grouting pipe is the only acoustic pipe specially used for ultrasonic testing in the market. The grouting pipe is made of cold and hard steel pipe after professional molding, and is connected by clamp pressure connection, screw connection, flange connection and other methods. It has a reliable anti-seepage effect during concrete pouring. Two convex grooves are planned at the end of the bell end of the high-strength double seal clamp type acoustic measuring pipe, and the convex grooves are equipped with sealing rings. When installing the device, the socket end of the product is stabbed into the bell end by cm, and then the two convex grooves are kneaded together with special hydraulic pliers. The pipe at the kneaded part is shortened and deformed after being stressed, and the outer pipe between the two convex grooves is deeply immersed into the inner pipe, and then the reliable connection of the product is completed; After being kneaded, the rubber sealing ring deforms and fits between the two layers of pipes, playing an excellent double safety sealing effect.Edessa ,How to connect the grouting water stop needle and the grouting pipe after the grouting water stop needle and the grouting pipe are connected, a set of grouting system will be formed. As long as the small part of the grouting needle is inserted into the joint of the lotus petal grouting pipe, a closed and self-locking grouting system will be formed. 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.Tecpan-Guatemala, The saddle shaped curved surface on the horseshoe surface of the grouting pipe and the upper and outer molds are not well fitted, which is caused by the Chengdu grouting pipe manufacturer&#;s failure to smooth (flatten) the grouting pipe along the horseshoe surface.Can the piston rod of the grouting pipe be protected to avoid being bruised and accelerating leakage?In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method, so that it can be used normally and improve the application quality of the grouting pipe. In the process of installing Jiangsu acoustic measuring tube, we should pay attention to the orientation of the installation hole. As long as the device is installed in a correct hole the Jiangsu acoustic tube can be used normally in the process of application, and the service life of Jiangsu acoustic tube can be improved. This is also the most important factor in the process of application in the future. If the hole fault is bragged about in the process of the device, the resistance of Jiangsu acoustic pipe will appear in the process of application, resulting in its damage. There is a great relationship between the accuracy of the hole and the quality after construction. In the process of construction, it is necessary to use the device according to the planned paper so that it can be used normally and improve the quality of use.In the process of application, because there will be many Jiangsu acoustic measurement pipes in the process of construction. In this way, the phenomenon of uneven stress will be formed. In the process of application, the phenomena of conflict and unusable will be formed. In order to prevent the phenomenon of surrounding each other, it is necessary to pay attention to the method of the device in the process of the device so that it can be used normally. The grouting pipe manufacturer introduced that the product quality of the grouting pipe is relatively stable, and when the mold is finalized, it is not easy to show defects. Most of the defects of the grouting pipe appeared in the trial production period and most of them were formed due to the unreasonable planning structure of the mold. The grouting pipe manufacturer will briefly introduce the treatment methods of defects as follows: wrinkle appearance and treatment methods. The so-called wrinkle refers to that there is a convex edge on the circular arc surface of the grouting pipe, some of which are straight to the nozzle, and often occur symmetrically at both ends of the center line, in the shape of 'eight'. Chengdu grouting pipe manufacturers mostly occur on the inner arc surface, and some occur on the outer arc surface.

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, the grouting pipe can also be used as the pipe for the defect washing and grouting treatment of the accident pile. At this 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, 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, 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. Classified according to the way in which the slurry enters the stratum to generate energy. Static pressure grouting: the slurry is transported by a grouting pump to make the slurry enter or permeate into the injected stratum hydraulically, which is called static pressure grouting.If any crack is found, it shall be repaired in time, otherwise, when the joint is deformed and subjected to water pressure,Edessa Expanded shell hollow grouting anchor manufacturer, 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.?Analysis project, 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. Sometimes the grouting pipe is overlaid on the two sides of the horseshoe surface. Adjust the cooperation specifications of the grouting pipe at the distribution nozzle. How to avoid grout leakage during installation of grouting pipe?Plastic pipe plastic pipe has a low acoustic impedance,Edessa Advance support of small conduit, which is used as a grouting pipe and has a large acoustic transmission rate. It can usually be used for smaller cast-in-place piles. It should be cautious when used in large-scale cast-in-place piles - because large-diameter piles need to be poured with a large amount of concrete, and the hydration heat of cement is not easy to dissipate. In view of the great difference between the thermal expansion coefficient of plastic and concrete, the plastic pipe will shrink radially and longitudinally due to the temperature drop after concrete solidification, It may be separated from the concrete locally to cause air or water crevices, and add more strong reflection interfaces on the sound path, which is easy to cause misjudgment.

It is safe and does not need to be welded on site.Safety and health,The glass fiber grouting pipe is a rigid product made of high-strength alkali free peeling fiber, which is made into a mesh base material through an internationally advanced fine knitting process and is surface coated. Unidirectional tensile plastic grouting pipe is a grouting pipe made of high-density polyethylene (HDPE) as raw material, plasticized and extruded plate, punched, heated and stretched, extruded and pressed, and then punched with regular hole network, and then stretched longitudinally. In this process, the polymer is in a directional linear state and forms an oblong reticular integral structure with uniform distribution and high node strength. The tensile strength and rigidity of the grouting pipe are fully improved through the reorientation of the originally scattered chain molecules into a linear state by stretching.[] when the utility model is in use, the flange plate is used to fix the utility model and the flange plate of the underground grouting pipe, the bolt is rotated with a tool, the cutting blade is adjusted to a certain position by the screw on the bolt, and then fixed, and then the screw cap of the blade is rotated and tightened to make the cutting blade and the pulley contact the inner surface of the grouting pipe with a certain contact force, that is, neither loose nor tight. The cutting blade and the pulley are directly inserted into the concave groove of the rotating device through the slot, and the cutting rotating device is fastened and rotated by a wrench or a tooth wrench and the pulley and the blade are driven to rotate by the rotation of the bolt, thereby rotating the casing. The pulley is located on the other side of the rotating device, corresponding to the blade. It is mainly used to reduce the friction between the rotating device and the casing wall, and fix the position of the blade in the casing, so as to prevent the blade on one side from shifting during cutting, failing to achieve the cutting purpose, or even damaging the blade. The fastening bolt is rotated by a wrench or tooth wrench, so as to drive the pulley and blade to rotate. The cutting rotating device cuts the casing. When the casing is cut to a certain depth, the blade nut is tightened again and the cutting continues until the casing wall is cut through. It has the characteristics of - times higher work efficiency than manual cutting and lower labor intensity of workers.Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.Edessa , Low cost,Edessa Hollow self-propelled anchor rod manufacturer, fast time, no loss, ranging from super high-rise and high-rise buildings to multi-storey buildings and indoor decoration construction. China has a longer history of using grouting pipes. Many of China&#;s ancient buildings have been listed as world-class material and cultural heritage, because China&#;s ancient buildings are very technical in construction. In China, before and in the early s, grouting pipes made of bamboo and wood were used in the construction of buildings. After the mounting bracket is welded on the surface of the grouting pipe, push the strain gauge in a stable and free state without bending and twisting; The mounting bracket and strain gauge shall be installed parallel to the support axis; When tightening the screw, pay attention to reasonably controlling the frequency of the strain gauge; The installation position of the strain gauge shall be selected at the position suitable for protection as far as possible. The length can be matched according to the construction requirements without loss.
