Embodiment Construction

[0028] According to attached figure 1 , in this embodiment, a combined construction structure of urban tunnels, rail transit sections and comprehensive pipe corridors is composed of urban tunnels, rail transit section tunnels and comprehensive pipe corridors.

[0029] Considering that urban underground roads need to form traffic conversion with surface roads and underground garages in surrounding plots, in order to meet the design requirements of urban roads and facilitate connection, urban tunnels are located on the ground floor. The urban tunnel is in the form of a rectangular double-chamber section, with up and down lines, and is separated by a middle partition wall 3. The cross-sectional size is determined by the lane scale, width, height limit, disaster prevention and evacuation, maintenance, decoration, electromechanical installation, etc.

[0030] The urban tunnel of the present invention, the rail transit section and the rail transit section in the combined constructio...

Abstract

The invention relates to a joint structure of an urban tunnel, a rail transit section and a comprehensive pipe gallery. The joint structure is composed of the urban tunnel, the rail transit section and the comprehensive pipe gallery. The urban tunnel is mainly composed of an upstream underground road and a downstream underground road, the rail transit section is divided into a left linear sectionand a right linear section, and the comprehensive pipe gallery is divided into a high voltage electricity chamber and a comprehensive pipeline chamber. The urban tunnel, the rail transit section and the comprehensive pipe gallery are designed and constructed together through the arranged mode that the urban tunnel and the rail transit section are of a co-plate structure and the urban tunnel and the comprehensive pipe gallery are of a co-wall structure. Under the premise of ensuring the normal operation of the service function of the urban tunnel, rail transit section and comprehensive pipe gallery, the utilization ratio of the urban underground space is increased, the construction cost is reduced, the influence on the environment and society during construction is reduced, and the comprehensive management efficiency of the construction and running of the underground infrastructure is also improved.

Description

technical field [0001] The invention relates to the field of urban underground engineering design and construction, in particular to the combined construction structure of urban tunnels, rail transit interval tunnels and comprehensive pipe corridors. Background technique [0002] With the rapid development of urbanization, large and medium-sized cities have problems such as land shortage, road congestion, and messy pipe networks. The development of underground space has become an effective way for human beings to improve the quality of life and promote human exchanges. [0003] According to the current level of development technology, urban underground space mainly includes underground roads, underground commerce, rail transit, comprehensive pipe corridors, drainage projects, and civil air defense projects. However, due to the asynchronous development timing of urban underground roads, rail transit, comprehensive pipe corridors and other underground spaces, the overall desig...
