Deep back filling soil infilled wall foundation construction method

Abstract

The invention discloses a deep back filling soil infilled wall foundation construction method, and belongs to the technical field of building construction. The method is characterized by comprising the following steps that step 1), a steel pipe pile (5) positioning line and a grade beam (7) controlling line are arranged on a back filling soil layer (2); step 2), pile holes are drilled in the backfilling soil layer (2) and a rock layer (1), and the steel pipe piles (5) are stretched into the pile holes; step 3), cement slurry is poured into the steel pipe piles (5); step 4) the position of theground beam controlling line is subjected to soil digging and is cleaned to be flat to form a ground beam pouring cavity, and separating layers are arranged between the ground beam pouring cavity andthe back filling soil layer (2) and between the ground beam pouring cavity and structural columns (3); step 5), ground beam steel bars and cushion layer steel bars are bound, and concrete pouring iscarried out to form a ground beam (7) and a cushion layer; and step 6), an infilled wall (6) is built on the cushion layer. According to the deep back filling soil infilled wall foundation construction method, the situations of pipeline deforming and infilled wall cracking caused by back filling soil settlement are avoided.

Description

technical field [0001] The invention relates to a construction method for filling a wall foundation with deep backfill soil, which belongs to the technical field of building construction. Background technique [0002] In current construction projects, especially in multi-storey public buildings, most of the foundation of a layer of filled wall masonry works is not backfilled; and the backfill depth is relatively thick, and the slight settlement of the foundation backfill over time after the backfill is completed, It caused problems such as cracking of cushion and filling wall, which affected the quality and safety of the project. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a foundation construction method for deep backfilling soil filling walls that can avoid problems such as cracking of the cushion and filling walls caused by the settlement of the backfilling so...
