Abstract

The invention provides a recyclable assembled foundation pit support construction method, which belongs to the field of foundation pit support construction and includes the following steps: S1, processing and checking soil nails, panels and backing plates; S2, soil nail positioning, Installation into the hole; S3, panel installation and fixation; S4, grouting between the panel and the slope of the foundation pit; S5, recycling the soil nails and panels after the foundation pit construction is completed to solve the construction process of the existing soil nail wall technology The failure to recycle the middle soil nails and hanging nets will easily lead to waste of resources and problems of low construction quality and construction efficiency due to the inability to achieve standardized construction during construction.

Description

technical field [0001] The invention relates to a recyclable assembled foundation pit support construction method. Background technique [0002] At present, the soil nailing wall support method is generally used in the construction process of foundation pit. The traditional soil nailing wall construction method is to reinforce the slope surface with dense soil nails during the layer-by-layer excavation process of the slope or foundation pit, and hang it. The mesh shotcrete makes it bond with the soil on the surface to form a composite to stabilize the slope surface. In the traditional soil nailing support construction process, soil nails and mesh shotcrete are non-reusable materials. After the foundation pit construction is completed It is buried in the foundation pit, causing a lot of waste of steel bars and concrete materials, and the soil nails buried in the foundation pit in the traditional soil nailing support system will affect the excavation of rainwater and sewage an...
