Even wall construction method capable of preventing concrete from streaming around

Abstract

The invention provides an even wall construction method capable of preventing concrete from streaming around. The method comprises the steps that S1, a reinforcement cage of a current groove segment is prefabricated, pulp stop iron sheets are welded to the outer sides of flange structural steel on the two sides of I steel, after the pulp stop iron sheet on the lower layer is laid, triangular supporting steel reinforcing ribs are welded to horizontal steel reinforcing ribs of the reinforcement cage and, after the pulp stop iron sheet on the upper layer is laid, according to the manner of arranging triangular supporting steel reinforcing ribs on the lower layer, the triangular supporting steel reinforcing ribs are laid on the pulp stop iron sheet on the lower layer; S2, the groove segment isgrooved, along with step-by-step lowering of the reinforcement cage, equal leg angles are added on flange plates on the two sides of the I steel in a welded manner, the specification of the equal legangles is L5cm*5cm*5mm, and the equal leg angles are arranged in a length passing manner from the bottom to the top of the I steel; and S3, a guide pipe method is used for pouring concrete to the groove segment. In the even wall pouring process, the concrete can be prevented from streaming around, construction work efficiency of adjacent groove segments can be improved, and the wall seam connection quality of two groove segments is firmer.

Description

technical field [0001] The patent invention relates to the field of ground wall construction, in particular to a ground wall construction method for preventing concrete from flowing around. Background technique [0002] As the enclosure structure of the subway station, the underground diaphragm wall has both soil retaining and water interception functions. It is recognized as the best soil retaining and water interception for deep foundation pits due to its advantages of good integrity, high rigidity, small foundation pit deformation, and excellent water sealing. The structure is widely used by design and construction units in the construction field of foundation pit enclosure structure due to its unique characteristics. However, due to the concealment of underground engineering, during the pouring process of the underground diaphragm wall, there is a high probability that concrete will flow around the gap between the I-beam flange plate and the groove wall to the adjacent g...

AI Technical Summary

Problems solved by technology

The concrete pouring height of this technical solution is easy to control and can guarantee the quality of the wall to a certain extent, but it does not take into account the situation that the concrete flows around from the gap between the I-beam flange plate and the tank wall to the adjacent tank section
