Continuous wall formwork and construction method of continuous wall

Abstract

The invention provides a continuous wall formwork and a construction method of a continuous wall. The continuous wall formwork comprises a formwork assembly, a first end face formwork and a second endface formwork. The formwork assembly comprises a formwork unit with a first steel frame plate, a second steel frame plate, a wall column, a balancing part, a first grouting branched pipe, a second grouting branched pipe and a fixing base. The wall column and the balancing part are installed at the two sides of the first steel frame plate correspondingly, and the wall column is provided with a first connector connected with the first grouting branched pipe, a second connector connected with the second grouting branched pipe and a grouting opening. The first grouting branched pipe and the second grouting branched pipe are provided with a first grout outlet hole and a second grout outlet hole separately. The first end face formwork and the second end face formwork are fixedly connected withthe two ends of the formwork assembly correspondingly. The wall column is fixedly installed on the fixing base. The continuous wall construction method used for conducting continuous wall constructionthrough the continuous wall formwork is further provided. The continuous wall formwork has the advantages of being good in firmness and high in stability. The construction method has the advantages that the construction technology is easy and construction is convenient.

Description

technical field [0001] The invention relates to the technical field of continuous wall construction, in particular to a formwork for a continuous wall and a construction method for a continuous wall using the formwork for the continuous wall. Background technique [0002] The underground diaphragm wall project is a basic project, and its main function is to pour out a wall to play the functions of water interception, seepage prevention, load bearing, water retention, etc., and then protect the buildings located inside the wall. The underground diaphragm wall at the pouring place can be applied to pump stations, pools, building foundation pits, underground oil depots and warehouses, etc.; it is also used for shafts of municipal pipe trenches and culvert shields; in addition, diaphragm walls can also be used as various deep foundations And anti-seepage walls of pile foundations, wharves, revetment, dry dock water conservancy and hydropower, open-pit mines, tailings dams and en...

AI Technical Summary

Problems solved by technology

[0003] However, during the construction of the existing underground diaphragm wall, the reinforcement cage needs to be bound, and the structure of the reinforcement cage is complicated, which increases the construction workload.

In addition, the hoisted reinforcement cage cannot form a stable connection with the bottom of the deep groove, resulting in poor stability and firmness of the reinforcement cage during the construction of the diaphragm wall, which is prone to shaking

Furthermore, when pouring concrete to the reinforcement cage, the concrete is injected into it through one or several conduits, so that the injection of concrete is likely to be uneven, the concrete injection of each part is not synchronized, and it is easy to generate voids, reducing the continuous underground. wall quality
