Embodiment Construction

[0020] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0021] Such as Figure 1 ~ Figure 3 The FRP strip-type foundation pit enclosure structure shown is installed around the foundation pit 6 to realize the foundation pit support, including positioning and laying out lines along the foundation pit 6 support, and inserting pipes made of FRP reinforcement materials into the leading holes. Pile 1, the three pipe piles 1 constitute a support pile body, located at the top of the pipe pile 1 and the position of the pipe pile 1 at the bottom of the excavation depth of the foundation pit 6. The hoop lock 2 of the pile 1, the hoop lock 2 includes steel hoops 4 surrounding and clamping the pipe pi...

Abstract

The invention discloses a FRP plate strip type foundation pit support structure and a construction method. The structure is mounted around a foundation pit for realizing the support of the foundation pit; the positioning paying-off is performed along the foundation pit support; pipe piles manufactured by FRP rib materials are inserted in leading holes; three pipe piles are formed to one set to form support pile bodies; hoop locks for holding the pipe piles and supporting the three pipe piles are respectively arranged at the tops of the pipe piles and in the positions of the pile piles at the dig depth bottom of the foundation pit; and FRP strip cloth is wound and connected among the pipe piles at the front sides of the support pile bodies. The FRP pipe piles are adopted, and the hoop locks are arranged to form transverse support and restraint for the support pile bodies, so that the support structure is more stable; the DRP strip cloth achieves a better soil stop effect, so that the type of the foundation pit support can be enriched, the selection range of the foundation pit support is widened, the construction period is shortened, and the energy conservation and the consumption reduction are realized; and the form of the foundation pit support can be expanded from a conventional plane mode to a space mode, so that the rigidity of the support structure is effectively improved, and the safety and the stability of foundation pit engineering are realized.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for foundation pit support by adopting an FRP strip-type foundation pit enclosure structure. Background technique [0002] The rational design of the enclosure system in foundation pit engineering is the core issue. At present, the enclosure types of foundation pit engineering mainly adopt steel sheet piles, reinforced concrete sheet piles, bored pile retaining walls, underground diaphragm walls, deep-mixed cement-soil gravity retaining walls, soil-nailed walls, and composite soil-nailed walls. These structural systems ensure the good engineering support of the pile foundation to a certain extent. However, the consumption of engineering materials is large, the construction period of the project is long, and the environmental pollution is serious. In the environment of energy saving and emission reduction, various supports The technology nee...
