Embodiment 1

[0021] Example 1: A construction method for an underground diaphragm wall, comprising the steps of:

[0022] (1) Guide wall construction, including leveling the site, measuring and positioning, excavating and processing spoil, binding steel bars, supporting formwork, pouring concrete, removing formwork and setting cross braces and backfilling the outside of the guide wall. Set up two small supports every one meter in the longitudinal direction of the wall to support the two guide walls. Before the concrete of the guide wall reaches the design strength, it is forbidden to drive heavy machinery on the side of the guide wall to prevent the guide wall from being deformed under compression;

[0023] (2) Manufacture of reinforcement cages. Reinforcement cages should be made according to the reinforcement diagram of the underground continuous wall and the division of unit groove sections. The reinforcement cages of the unit groove sections should be assembled into a whole. When makin...

Abstract

The invention discloses a construction method for an underground diaphragm wall. The construction method comprises the following steps of (1) constructing a guide wall, (2) manufacturing reinforcement cages, (3) manufacturing slurry, (4) grooving, (5) lifting and putting the reinforcement cages down, (6) pouring concrete underwater and (7) treating wall section joints. According to the construction method for the underground diaphragm wall, the problems that adjacent wall sections can not be aligned and leak water are solved, the effect is obvious, and the construction method can be applied and popularized in actual construction.

Description

[0001] technical field [0002] The invention relates to a construction method of an underground continuous wall, belonging to the technical field of building construction. Background technique [0003] The excavation technology of underground diaphragm wall originated in Europe. It was developed based on the method of drilling wells and oil wells using mud and underwater pouring of concrete. In 1950, Milan, Italy first adopted the construction of retaining mud underground diaphragm walls. In the 1950s and 1960s, this technology was developed in western developed countries. It was promoted in the former Soviet Union and became an effective technology in underground engineering and deep foundation construction. [0004] Generally, the underground diaphragm wall can be defined as: using special trenching equipment on the ground to excavate narrow and long trenches along the periphery of the foundation pit according to the pre-marked section. Stable, the trench adopts a spec...
