Description

A kind of integrated pipe corridor and its using method

technical field

The invention relates to the technical field of municipal infrastructure construction, in particular to a comprehensive pipe gallery and its use method.

Background technique

The comprehensive pipe gallery is two or more box culvert tunnels built underground in the city to accommodate urban pipelines such as water supply, drainage, natural gas, electricity, and communications. The unified planning and management of the municipal pipe network can be realized through the construction of the comprehensive pipe gallery.

The Ministry of Housing and Urban-Rural Development's "Notice on Improving Urban Drainage and Waterlogging Prevention Capability and Promoting the Construction of Urban Underground Comprehensive Pipe Gallery" pointed out that urban drainage and waterlogging prevention should be promoted in coordination with urban underground comprehensive pipe gallery and sponge city construction. The role of waterlogging, stagnation, storage, purification, utilization, and drainage is to build an urban drainage and waterlogging prevention engineering system with the main content of "source emission reduction system, drainage pipe and channel system, waterlogging and risk relief system, and emergency response system for exceeding standards", and cooperate with the city Flood control planning is well connected.

The existing rainwater drainage design is roughly divided into two types: one is the traditional method of laying rainwater pipes underground on both sides of the road by using open and cut methods. The other is to drain rainwater directly into the domestic drainage pipes set in the cabins of the integrated pipe gallery. The first layout method above is the traditional open cut and straight row method. This method needs to excavate the road surface, resulting in a "zipper of the road" in the city. At the same time, it cannot achieve the unified entrance of municipal pipelines. This method should be eliminated. Although the second method mentioned above can be understood as rainwater and domestic sewage sharing a pipeline, it also meets the requirements of the pipeline entering the corridor. However, since the domestic sewage purification process is much more complicated than the rainwater purification treatment, domestic sewage purification needs Large-scale equipment and instruments, and rainwater can be used for farmland irrigation and other purposes with simple or even no treatment. If the rainwater is directly discharged into the domestic sewage pipeline, the amount of domestic sewage to be treated will be greatly increased, and the cost of sewage purification and treatment will be increased.

A method for using a comprehensive pipe gallery, in which any one of the above-mentioned comprehensive pipe galleries is respectively constructed and arranged on both sides and in the middle of the lower part of the road surface, forming three drainage paths for precipitation on the road surface;

When the precipitation on the road surface is small, the accumulated water on the road above the comprehensive pipe gallery will be collected into the water collection tank through the drainage cover plate, and the water collection tank will be initially collected, and then the rainwater will flow into the drainage tank through the connecting pipes set on the bottom of the water collection tank. Drainage pipes are responsible for the collection and transportation of rainwater;

When the precipitation on the road is too large, the accumulated water on the road is collected into the water collection tank through the drainage cover, and then the rainwater flows into the drainage pipe in the drainage cabin through the connecting pipe set on the bottom of the water collection tank. When the drainage pipe is full, the rainwater directly Collected in the water collection tank, at this time, the drainage tank and the water collection tank jointly undertake the functions of collecting and transporting rainwater.

Compared with the prior art, the present invention has the following beneficial technical effects:

The present invention has simple structure, fewer technical requirements, and convenient construction. By arranging a water collection tank and a drainage tank on the side of the integrated pipe gallery body, the functions of rainwater collection, discharge, and short-term storage are realized. The attached cabin realizes the requirement that both rainwater collection facilities and drainage facilities enter the corridor. During the construction, the cabins on both sides are constructed together with the main body of the comprehensive pipe gallery. After the construction is completed, unified management is carried out to achieve unified management of rainwater collection pipelines and drainage pipelines and other municipal pipelines such as power and communication, which is convenient for later management and operation and maintenance. This kind of comprehensive pipe gallery pioneered the design of a water collection chamber dedicated to collecting road surface precipitation, and realized the collection and discharge functions of precipitation through the mutual cooperation of the water collection chamber and the lower drainage chamber. The rain and sewage collection and discharge of this kind of comprehensive pipe gallery are divided into two situations: when the precipitation on the road surface is small, the rain and sewage pass through the water collection tank and are directly discharged into the drainage pipeline in the drainage cabin. At this time, only the drainage pipeline is responsible for collecting Water and drainage functions, the upper water collection chamber only plays the role of sand separation, mud separation and middle channel; when the precipitation on the road surface is heavy, when the lower drainage pipeline is fully loaded, the upper water collection chamber participates in water collection and drainage. The lower drainage compartment jointly undertakes the functions of water collection and drainage. This kind of comprehensive pipe gallery has two water collection and drainage defense lines to ensure that the city will not "look at the sea" phenomenon during heavy rain. At the same time, because of this design, the precipitation on the road surface is collected in the underground space of the road surface for later use, which is in line with the sponge city construction concept.
