Installation method of novel duct piece for meeting effective connection and seepage prevention of open caisson

Abstract

The invention discloses a novel segment mounting method for meeting effective connection and seepage prevention of an open caisson, which comprises the following steps of: annularly splicing a bottom-layer blade foot segment, a prefabricated segment and a vertical shaft top segment in sequence to respectively form a bottom-layer blade foot segment ring, a prefabricated segment ring and a vertical shaft top segment ring; vertical reinforcing steel bars or bolt pin rods are inserted into the vertical through grooves or the vertical bolt pin holes of the bottom-layer blade foot pipe pieces, the prefabricated pipe pieces and the vertical shaft top pipe pieces, and vertical connection between the pipe pieces is achieved; inserting reinforcing steel bars into the reinforcing steel bar connecting grooves of the bottom-layer cutting edge segment, the prefabricated segment and the vertical shaft top segment, and connecting the reinforcing steel bars with the reinforcing steel bar connecting grooves to realize annular and vertical connection of the segments; and concrete is injected into the grouting groove and enters a cavity formed by the outer-layer pipe piece, the inner-layer pipe piece and the connecting plate, so that the bottom-layer blade foot pipe piece, the prefabricated pipe piece and the vertical shaft top pipe piece are connected into a whole. The method has the advantage that the anti-seepage performance and the connection strength of the duct piece are enhanced.

Description

technical field [0001] The invention relates to the technical field of caisson construction, in particular to an installation method of a novel segment for satisfying the effective connection and seepage prevention of the caisson. Background technique [0002] With the popularization of family cars, in cities with high population density, the difficulty of parking has become a major problem for citizens to travel. However, due to the shortage of urban land and limited available space, it is difficult to develop enough ground on the basis of existing construction. Space facilities to effectively solve the problem of parking difficulties. Since the caisson-type underground parking garage can minimize the use of the limited urban ground space, it develops to the deep underground space in the urban area. At the same time, with the help of new artificial intelligence technology, it can effectively realize the optimal allocation of garage resources, and it will surely become an ur...
