Pipe segment splicing method for segmental prefabricated underground pipe gallery

Abstract

The invention relates to the technical field of underground pipe gallery building construction, in particular to a pipe segment splicing method for a segmental prefabricated underground pipe gallery. The pipe segment splicing method comprises the steps that pipe segment parts are conveyed into pipe segment splicing equipment; the pipe segment parts are spliced into an annular pipe segment in the pipe segment splicing equipment; squeezing and pushing acting force is applied to the pipe segment to force the adjacent pipe segment parts to be tightly connected into a whole; then the pipe segment is jacked and pushed to a designed position to be connected with an adjacent pipe segment against the pipe gallery building direction; and the splicing working procedure is completed. The pipe segment splicing mode is convenient to operate, can be widely applied to various open cutting pipe gallery building construction, lowers the pipe segment conveying difficulty, reduces pipe segment conveying cost, improves the pipe segment splicing precision and has great popularization value.

Description

technical field [0001] The invention relates to the technical field of construction and construction of an underground pipe gallery, in particular to a segment assembly method for a segmented prefabricated underground pipe gallery. Background technique [0002] Segment-assembled shield technology is an important part of the construction of underground shield tunnels. By assembling the segments into a ring structure, and then compressing the segments through the extrusion force of the soil around the tunnel, the locking function of the segments is realized. The segment assembly in this mode only needs to roughly position and install the segments in the shield body of the shield machine. After the segments come out of the tail of the shield, the final locking between the segments can be completed by using the extrusion of the soil, and the gap between the segments can be realized. Shear force transfer between waterstop seals and segment joints. For the construction of the seg...

AI Technical Summary

Problems solved by technology

For the construction of the segmented prefabricated assembled underground pipe gallery structure using the open-cut mode, since the upper part of the pipe gallery is open without soil coverage after the assembly of the pipe gallery segments is completed, and there is no soil extrusion effect, it is impossible to complete the assembly of the segments along its The extrusion and self-locking process in the radial direction cannot immediately realize the sealing of the water stop strips between the segments and the shear force transmission requirements between the segment joints before the top is backfilled with soil
