Abstract

The invention discloses a drilling cast-in-place pile reinforcing mesh fixing structure and method. The structure comprises a plurality of transverse compression bars, a plurality of longitudinal compression bars, reinforcing mesh sheets, J-shaped anchor bars and fine aggregate concrete. The two ends of the transverse compression bars are implanted into slope protection piles, the plurality of longitudinal compression bars and the transverse compression bars are mutually crossed, welded and fixed, and the reinforcing mesh sheets are internally attached to the sides, facing inter-pile soil, onthe inner sides of the transverse compression bars and the longitudinal compression bars; long straight sections of the J-shaped anchor bars are implanted into the inter-pile soil, bent sections of the J-shaped anchor bars penetrate through the reinforcing mesh sheets and hook the transverse compression bars and the longitudinal compression bars, and implanting holes, where the J-shaped anchor bars are implanted, in the inter-pile soil are filled with mortar fixedly; and the fine aggregate concrete is sprayed to the sides, facing the interior of a foundation pit, on the outer sides of the transverse compression bars, the longitudinal compression bars and the reinforcing mesh sheets. The inter-pile support detailed node treatment can greatly improve the stability and safety of a pile foundation retaining wall, the inter-pile soil can be effectively fixed, and safety of foundation pit support and the overall stability of the foundation pit are ensured.

Description

technical field [0001] The invention relates to the field of foundation pit support construction, in particular to a fixing structure and a fixing method for a reinforced mesh of a bored pile. Background technique [0002] In the process of building construction, the support between piles will affect the safety of the foundation pit. The traditional form of retaining wall between piles is often fixed by steel mesh and reinforced by shotcrete. The quality of retaining wall between piles cannot be effectively guaranteed. Contents of the invention [0003] The invention mainly aims at the deficiencies of the prior art, and provides a fixing structure and a fixing method for the reinforced mesh of bored piles, which can improve the stability of the soil retaining wall between the piles, and increase the safety and stability of the foundation pit support. [0004] The technical solution adopted in the present invention is: a fixed structure of reinforced mesh of bored piles, wh...
