A reinforced cage structure for an underground continuous wall

Abstract

The invention discloses a reinforcement cage structure for an underground continuous wall. The reinforcement cage structure comprises a plurality of head-opened reinforcement steel bar frameworks located in deep grooves at intervals and closed reinforcing steel bar frameworks located between the head-opened reinforcement steel bar frameworks which are separated. Transverse baffles matched with the corresponding deep grooves are fixed to the two ends, in the longitudinal direction, of each head-opened reinforcement steel bar framework. Head-opened anti-seepage slurry cloth is connected to the positions, close to the two side walls of the corresponding deep grooves, between the baffles at the two ends of each head-opened reinforcement steel bar framework. A head-opened pouring space surrounding each head-opened reinforcement steel bar framework is defined by the head-opened anti-seepage slurry cloth, the transverse baffles and the deep groove bottom walls of the head-opened reinforcement steel bar framework. Head-opened parts and closed parts can be directly formed through pouring, the construction efficiency is high, cost is low, and no water seepage situation can happen.

Description

technical field [0001] The invention relates to an underground continuous wall, in particular to a steel cage structure for an underground continuous wall. Background technique [0002] The underground continuous wall is a continuous wall built below the ground for water cut-off, seepage prevention, soil retaining, or load-bearing. composition. [0003] The construction of the traditional underground diaphragm wall includes the following steps: a. Dig out multiple sections of the first deep groove with a certain interval by the grab machine. Put in the steel skeleton for the first opening; b. After hoisting the steel skeleton for the first opening welded on the construction site into the deep groove for the first opening, pour concrete slurry into the deep groove for the first opening; c. After the concrete slurry solidifies, form a section with a length greater than the actual required For the first opening wall, at this time, use the excavator to grab the soil between th...

AI Technical Summary

Problems solved by technology

[0004] The underground diaphragm wall built by this construction method has the following deficiencies: 1. After digging and pouring concrete and forming a wall longer than the first opening, then dig out the redundant parts of the two sections of the wall to form the first opening and dig out The soil between the two is poured to form a closed width by forming a closed deep groove. Obviously, its work efficiency is low and the construction period is increased.

2. The wall formed in the first deep groove must be grabbed by a grab machine before it is finally formed into the first opening. The excess part that is grabbed will become waste, resulting in waste of raw materials and increased costs

3. After the redundant two sides of the two separated walls are dug out and become the first opening, the surfaces of the two longitudinal sides are difficult to be well connected with the concrete slurry poured in the closed deep groove, resulting in the first opening and the first opening after forming. There is a gap between the closed widths, which is prone to water seepage
