Construction sequence: remove the cement residue and attached floating soil on the foundation surface. Use vise to cut it pipe with proper length, and each loop is 4m according to the paper requirements. Put the outer layer of fabric into the blue horn interface to try the tensile property and confirm that it has been inserted to the end. The other end of the horn is sleeved with a PVC reinforced grouting pipe. It pipes shall be arranged according to the direction of construction joints, and installed 150mm away from the back water surface. Note that the green it pipe itself cannot be exposed to the concrete to be poured, and ensure that the PVC pipe is exposed outside the concrete for grouting in the future. Cement nail fixing clips or iron wires shall be used for fixing every other distance, and the distance between two fixing points shall be ≤ 30cm. The ends of it pipes of two adjacent circuits must overlap by at least 10cm. The exposed PVC pipe is installed in the grouting interface box to facilitate grouting in the future.
Calgary.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, 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, complete supply; The grouting pipe can be cut at the construction site according to the actual required length of the joint (it is recommended that the longer grouting outlet length should not exceed 6m); No special installation equipment is required; Grouting time can be arbitrarily selected; When grouting is carried out internally under proper pressure the grouting pipe fluid can keep filling the whole pipe evenly; The system allows grouting under relatively low pressure; The grouting pressure is 0.2-0.4mpa; The installation will not affect the characteristics of the building grouting pipe; The installation or grouting process will not harm the concrete; Permanent sealing can be ensured after grouting; If there is no leakage,Calgary32lead small conduit, grouting is not allowed.

It can be widely used for one-time multiple grouting pastes.
When grouting in the grouting pipe under pressure, the grouting can keep filling the whole pipe evenly.
The repetitive grouting pipe can be reused for many times, and its internal pressure can reach 150bar or more.
Slump test shall be carried out for concrete entering the site. No less than 3 groups of test pieces shall be made for the same batch of concrete with the same strength grade. One group is used for standard curing, and the other two groups are used for curing under the same conditions to determine demoulding and allowable lifting time. How to deal with the joint if the grouting pipe is installed in sections? If the grouting pipe is installed in sections, the joints must be welded. The welded joints of the section steel have been prepared in the manufacturing plant, and can be installed after the two-phase adjacent joints are aligned. After all beams are welded, anchor them according to the above steps. Install the formwork at the beam end. The formwork shall be made according to the overall dimensions of Hainan grouting pipe device and the notch of the reserved slot. The formwork shall be made quite tight to prevent mortar from flowing into the displacement control box or into the beam end gap.
Inspection items. The grouting pipe has good flexibility. When the pipe is produced it can be coiled, so that the number of joints in the pipe network can be reduced. It can be laid according to the terrain, easily bypass obstacles, and is convenient for construction.
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.
Squeeze grouting or split grouting: depending on the grouting pressure, the grout is forced to open various channels in the underground layer to squeeze into the stratum. The grout is mostly consolidated in a vein or a tree shape. This grout can squeeze the soft bottom layer tightly, so it is also called compaction grouting in foundation reinforcement. Displacement grouting: the soil and sand in the injected stratum are forced out through certain methods, and the space formed is filled with grout, It is called displacement grouting High pressure mass injection grouting: the kinetic energy of jet flow is used for grouting.
When grouting in the grouting pipe under pressure, the grouting can keep filling the whole pipe evenly.
The cheapest.After the sodium hydroxide solution is poured in, the calcium chloride solution is poured in, which is called the two liquid method. Alkali solution method has the advantages of simple construction equipment, low reinforcement cost, and elimination of collapsibility of loess.
Answer: according to the length and diameter, the weight of common grouting pipe is 0.1 ~ 0.3KG, 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 rear box of a tricycle was originally supported by an iron bar (which is still useful). Now, 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, medical treatment, fitness, kitchen cabinets, etc, If you need to know the and use of the grouting pipe, please feel free to consult me, 1076kg per piece. Results the average weight of 10 100 * 100 * 6mm grouting pipes was 1026kg, with a difference of 15kg per ton. It can be imagined how big the gap is when the one foot rate of retreat is large.
Calgary.Green grouting materials mainly refer to industrial wastes such as fly ash slag and steel slag. It can be excited by alkali, and its solid particles are smaller than ordinary cement particles, and the particle gradation distribution is more reasonable. Therefore,CalgaryDouble layer small conduit advance support, it can be used as a raw material for grouting materials.
