Semi-fabricated pipe curtain structure and construction technology based on steel-concrete connection

Abstract

The invention discloses a semi-assembled pipe curtain structure based on a steel reinforced concrete connection. The semi-assembled pipe curtain structure comprises lateral supporting structures and atransverse supporting structure, wherein the lateral supporting structures are used for supporting lateral surrounding rock, the transverse supporting structure is used for supporting the ground, thelateral supporting structures are connected through the transverse supporting structure, each of the lateral supporting structure and the transverse supporting structure comprise a plurality of largesteel pipes, the adjacent large steel pipes are connected through a prefabricated connecting component, and concretes I are filled in the large steel pipes for packaging the prefabricated connectingcomponent. The construction process of the semi-assembled pipe curtain structure based on the steel reinforced concrete connection comprises the following steps of 1, manufacturing a working well; 2,prefabricated connecting members outside the field; 3, installing a pipe curtain; 4, forming a pipe curtain structure; and 5, grouting reinforcement treatment and building a building. The manufacturing process of the prefabricated connecting component is standardized, the concrete pouring quality of the prefabricated connecting component is guaranteed, and the phenomena of insufficient concrete pouring compactness and internal concrete missing are avoided.

Description

technical field [0001] The invention belongs to the technical field of underground engineering construction, and in particular relates to a semi-fabricated pipe curtain structure and construction technology based on steel-concrete connection. Background technique [0002] The pipe curtain method is based on the jacking of a single steel pipe in the underground soil structure, using the pipe jacking technology to jack multiple densely packed large-diameter steel pipes around the proposed underground building, and using the inter-pipe cutting technology to cut the steel pipes. Cut the operation hole for piercing through the steel bars and cleaning the dregs between the steel pipes, manually clean up the dregs in the large steel pipes and between the steel pipes, and then penetrate the bolts or steel bars horizontally between the large steel pipes, and then, in the large steel pipes and Concrete is poured on site between the steel pipes, and the large steel pipe concrete is hor...

AI Technical Summary

Problems solved by technology

However, when the cross-sectional size of the connected steel pipes is small, or the horizontal distance between large steel pipes is large, there may still be insufficient concrete pouring in the connected steel pipes, or even the lack of concrete in the connected steel pipes, which also cannot guarantee the pipe curtain structure. Good bearing capacity and rigidity will also bring safety hazards to subsequent underground construction

In view of the shortcomings of the above-mentioned pipe curtain structure and the difficulties in construction, it is of great practical significance to develop a new pipe curtain structure with simple construction and guaranteed quality
