Demountable composite material face plate brad supporting system

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 ...

AI Technical Summary

Problems solved by technology

[0003] The existing soil nail wall foundation pit support is composed of soil nails and reinforced concrete surface layer, which is an accessory part of the permanent building. However, after the service period of the support system, these soil nails and surface layers will lose their function and become underground obstacles. , which brings inconvenience to the surrounding civil construction; at the same time, this is a waste of economic loss and resources, which does not meet the requirements of sustainable development of resources; in addition, the soil nail wall support does not make full use of the self-supporting capacity of the soil, resulting in no Necessary waste (as shown in Figure 6, the soil arch effect in the middle part decomposes the force, so it has a certain self-supporting effect)
