Wenzhou PVC inclinometer pipe production plant PVC inclinometer pipe quotation

Description :

　　Deep inclinometer can intuitively reflect the trend of changes in soil deformation monitoring of foundation pits, and plays an important monitoring role in foundation pit deformation monitoring. Therefore, we must pay attention to this. In the previous article on the working principle of inclinometers, some relevant principles and requirements for burying inclinometers were mentioned, but the burial and observation methods of inclinometers were not elaborated in detail. In the following content, we have provided some detailed explanations on these two aspects. I hope everyone can learn and apply it in daily monitoring.

　　(1) Monitoring scope

　　Deep level horizontal displacement monitoring holes should be arranged at the center and representative locations of the foundation pit slope and retaining (pile) wall, with the number and spacing depending on the specific situation (usually indicated on the design drawings). The holes should be symmetrically arranged on both sides of the foundation pit, but at least one monitoring hole should be set on each side. The location of the buried measuring points can refer to the deep excavation inclinometer monitoring plan

　　(2) Measurement point burial and technical requirements

　　1) Burial method

　　The inclinometer pipe is tied and buried. The inclinometer tube is directly tied and fixed to the reinforcement cage of the retaining pile. After the reinforcement cage is inserted into the groove (hole), concrete is poured.

　　2) Technical requirements for burial

　　Due to the construction conditions on site, the installation and protection of inclinometers are relatively difficult, and the finished product rate is low. Therefore, the installation and installation of inclinometers for supporting structures should follow the following principles:

　　① The bottom of the pipe should be level with or slightly lower than the bottom of the steel cage, and the top should reach the ground (or the top of the guide wall). The top of the inclinometer tube should be protected as much as possible. For example, during on-site installation, we can use steel pipes as protective covers to cover the upper part of the inclinometer tube. As the inclinometer tube is made of PVC material, it is easy to break. In addition, on-site construction often uses fragmentation cannons to clean the heads of retaining piles, which can easily damage the inclinometer tube. When using steel pipes for protection, cut off the protective steel pipes after cleaning the pile head. Fill the pores between the steel pipe and the inclinometer pipe with pea gravel concrete or cement mortar to stabilize the inclinometer pipe. This can protect the inclinometer tube and improve the yield of inclinometer tube installation.

　　② The reinforcement cage of the inclinometer pipe and the supporting structure should be tied and buried, with a binding spacing of no more than 1.5m.

　　③ The inner lining of the upper and lower pipes of the inclinometer tube is well connected without gaps, and the joint is firmly fixed and sealed.

　　④ When tying the pipe, the direction should be adjusted so that a pair of measuring slots inside the pipe are perpendicular to the measuring surface (i.e. parallel to the displacement direction).

　　⑤ Seal the bottom and top, keeping the inclinometer tube clean, unobstructed, and straight.

　　⑥ Make clear markings and reliable protective measures
