Abstract

The invention discloses an underground continuous wall anti-flow-around rubber pipe and an H-shaped steel combined connecting joint and a construction method thereof. The connecting joint comprises agroove wall, unit groove section underground continuous wall steel reinforcement cages, concrete, H-shaped steel, angle steel and a semicircular locking pipe, wherein the H-shaped steel is used as a rigid connecting joint for connecting two adjacent underground continuous wall steel reinforcement cages; vertical through-length angle steel is symmetrically arranged on the outer side of the H-shapedsteel; the semicircular locking pipe comprises a semicircular steel pipe, an inner supporting plate and a thin steel plate; the thin steel plate is fixed at the diameter port of the semicircular steel pipe; and after the semicircular locking pipe enters the groove in advance, the positioning action is performed on the groove of the H-shaped steel. The rubber pipe thoroughly solves the problem offlow around the concrete pouring of the underground continuous wall, achieves the rigid connection of the steel reinforcement cages of the underground continuous wall of each unit groove section, is convenient for field construction operation, can be repeatedly used, has relatively low manufacturing cost, and has great popularization and application values.

Description

technical field [0001] The invention relates to the construction field of building underground engineering, and more specifically relates to a connection joint combined with an anti-flow rubber hose of an underground diaphragm wall and H-shaped steel and a construction method. Background technique [0002] As a supporting structure, the underground diaphragm wall is widely used in the excavation of underground engineering foundation pits such as subway stations and high-rise buildings. It can also be used as the outer wall of the underground engineering structure. The construction steps of the underground diaphragm wall mainly include: guide wall construction → excavation of the unit trough section → bottom cleaning and grout replacement → lowering the joint structure → fabrication and placement of the steel cage → pouring concrete for the unit trough section → connecting adjacent unit trough section walls rise to form a closed reinforced concrete envelope. Among them, eff...
