Splicing method of honeycomb type underground engineering structure system

Abstract

The invention discloses a splicing method of a honeycomb type underground engineering structure system. The splicing method is characterized by comprising the following steps: splicing and combining a plurality of prefabricated pipe sections to form the honeycomb type underground engineering structure system which is composed of at least two regular hexagon pipe bodies; and forming corners of the regular hexagon pipe bodies on each prefabricated pipe section. The splicing method of the honeycomb type underground engineering structure system has the following advantages: (1) the whole structure system is formed by quickly splicing and combining the prefabricated pipe sections, and in addition, Y-shaped pipe sections and 120-degree bent pipe sections are adopted and can improve the connecting strength and sealing performance of the corners of the whole structure system; (2) the length space area of a main wall body is expanded; (3) the whole honeycomb type underground engineering structure system achieves the unified planning, design and performing of the underground engineering, so that the underground space is intensively utilized, and as a result, a valuable space is reserved for urban development; and (4) the underground engineering quantity is saved, and the stability and firmness of the whole honeycomb type underground engineering structure system are improved.

Description

technical field [0001] The invention belongs to the technical field of underground engineering, and in particular relates to an assembling method for a honeycomb underground engineering structure system. Background technique [0002] At present, domestic underground tunnels and pipe galleries are mostly designed with rectangular or circular cross-sections, and municipal projects are designed separately and not shared with each other. It is also necessary to reserve a certain safety distance to ensure the safety of the structural system of each section, which will cause great waste for the use of underground space, and the space for the layout of integrated pipelines is relatively cramped. The circular section is also relatively limited in the design and implementation of the combination of underground space tunnels and municipal trenches. [0003] At present, among the cross-section forms of tunnels or pipe galleries in underground engineering, the circular cross-section ha...

AI Technical Summary

Problems solved by technology

[0003] At present, among the cross-section forms of tunnels or pipe galleries in underground engineering, the circular cross-section has good stress, small reinforcement, and is not easy to crack; the rectangular shield cross-section has good space utilization and poor stress.

Regardless of circular, rectangular or any single shape, it only improves a certain performance of the single section; the phased implementation of multi-line sections and related underground projects requires protection measures and reserved safety distances for the respective projects. Space will cause a lot of waste
