Embodiment Construction

[0031] The present invention aims at the disadvantages of the existing soil nail wall, and proposes a detachable composite material panel soil nail support system based on the traditional soil nail wall foundation pit support technology, which will be described in conjunction with the accompanying drawings below.

[0032] In the structural diagrams of the detachable composite material panel soil nail support system shown in Fig. 1, Fig. 2 and Fig. 3, the soil nail 3 is fixed on the wall 6 of the foundation pit, and the detachable composite material panel 1 consists of nuts 2 and gaskets. 4 to form a detachable anchor fixed on the surface of the waterproof device 5 between the boards. The part of exposed wall foundation pit wall of soil nail 3 has screw thread 7. After the service period ends, the composite material panel 1, the nut 2 and the gasket 4 can be disassembled to continue serving for the next project.

Abstract

The invention discloses a detachable composite material panel soil nail support system, which belongs to the technical field of building auxiliary engineering. The soil nails are fixed on the wall of the foundation pit, and the detachable composite panels are fixed on the wall of the wall foundation pit by detachable anchors and soil nails, and are connected by waterproof devices between the panels. After the service period is over, the composite panel can be disassembled to continue serving for the next project. The detachable composite panel is made of resin-based fiber composite material, mainly because of its light weight, high specific strength, large specific modulus, and good fatigue resistance. Compared with the traditional soil nail wall construction, the construction speed of the detachable composite panel support system is fast and saves time: the detachable composite panel soil nail support system is better than the traditional one in controlling the distribution of the plastic zone of the foundation pit and the deformation of the foundation pit. Soil nailed wall, good safety.

Description

technical field [0001] The invention belongs to the technical field of building auxiliary engineering, and in particular relates to a detachable composite material panel soil nail support system. Background technique [0002] Existing soil nail wall foundation pit support technology is widely used, and is mainly used for fixing technology of river courses, slopes on both sides of roads, and building walls and foundation pit walls to prevent landslides from collapsing. Various structures are different. Such as Tan Yuehu discloses a kind of foundation pit supporting method and supporting construction soil nails with composite soil nails in Chinese patent CN1380472, CN2542724, make multi-row self-drilling type soil nails support expansion on the water-stop curtain, this The production of self-drilling soil nail support adopts first to introduce holes on the water-stop curtain, then pass the soil nails through the pilot holes and drill them into the soil layer, and inject grout ...
