Description

Double-layer integrated corridor

technical field

The invention relates to the technical field of urban comprehensive pipe gallery, in particular to a double-layer comprehensive pipe gallery.

Background technique

The comprehensive pipe gallery is a structure and ancillary facilities built underground to accommodate two or more types of urban engineering pipelines. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, which is an important basis for ensuring urban operation Facilities and "lifelines". The construction of comprehensive utility corridors can effectively eliminate urban "pull links", ensure smooth road traffic, and ensure safe operation of underground pipelines.

In the construction scope of some comprehensive utility corridors, the layout of the utility corridors is narrow, and there are many types of pipelines that need to be included in the comprehensive utility corridors, and some pipelines have large diameters, which requires a large space for the comprehensive utility corridors. For the project of building a comprehensive pipe gallery after the road is repaired or within the scope of the road section, there are other facilities that occupy a large space. At this time, it is required to excavate the road surface or the pipe gallery as little as possible during the planning and design stage of the comprehensive pipe gallery. It is required to occupy as little space as possible on the cross-section of the road, and the integrated pipe gallery needs to occupy a certain amount of space in order to meet the requirements of personnel maintenance and pipeline installation and operation.

In order to meet the hoisting, ventilation and escape requirements of each cabin, the layout of the comprehensive pipe gallery is generally arranged in a single layer. The comprehensive pipe gallery arranged in this form will be used when there are many pipelines entering the corridor or the diameter of the pipe entering the corridor is large. Occupy a wider road space. The implementation space provided by some road construction is small. For example, when it is arranged in parallel with the subway and other facilities, the comprehensive utility gallery must occupy as little space as possible on the road cross section, otherwise it cannot meet the planning, design and implementation requirements.

In order to save the space occupied by the comprehensive pipe gallery on the cross-section of the road, and at the same time meet the space requirements of the comprehensive pipe gallery specification, the comprehensive pipe gallery of some projects adopts a double-layer layout to reduce the occupancy of the road plane space. However, in the existing double-layer integrated pipe gallery, the lead wire branch of the lower cabin is set at the bottom or side of the pipe gallery, deepening the buried depth of the bottom of the pipe gallery or increasing the occupation of side space is not conducive to reducing the occupation of space; In addition, when feeding and hoisting the existing double-layer integrated pipe gallery, the feeding and hoisting port of the lower cabin is set at the bottom or side of the lower layer of the pipe gallery, which deepens the buried depth of the bottom of the pipe gallery or increases the occupation of side space, which is not conducive to reducing the load on the pipe gallery. Occupation of space; when the lower cabin of the existing double-layer integrated pipe gallery is ventilated, it is necessary to set up a separate ventilation channel on the side of the integrated pipe gallery, which increases the occupancy of the side space; at the same time, it is necessary to feed materials at the bottom of the lower layer of the integrated pipe gallery When hoisting and wiring, the local buried depth at the bottom of the comprehensive pipe gallery will increase, and the drainage system of the comprehensive pipe gallery needs to be set up separately, resulting in difficult construction and high cost investment.
