Description

A structure combining rain and sewage diversion and pipe gallery

technical field

The utility model belongs to the technical field of municipal drainage, in particular to a structure combining rainwater and sewage diversion with a pipe gallery.

Background technique

The drainage system of urban drainage pipe network in my country mainly has three forms: combined system, intercepted combined system and diverted system. At present, the drainage of old urban areas in many domestic cities is restricted by economy, technology and ideas. In the early construction, the municipal drainage pipelines were not synchronized with the construction of residential areas, resulting in the common phenomenon of mixed connection of pipelines in old urban areas. The confluence system and diversion system in each drainage area Alternate existence, drainage system disorder. On the one hand, it causes a large amount of sewage to flow into the river water body, resulting in the deterioration of the water environment. On the other hand, it leads to an increase in the operating pressure of the sewage pipe network and sewage treatment plant, resulting in the inability to achieve 100% treatment of sewage.

Combined with relevant engineering examples, in the design of directly buried rainwater and sewage pipelines, when the combined rainwater and sewage pipelines are discharged into the downstream rainwater and sewage diversion pipelines, the sewage interception wells should be used for diversion. As shown in Figures 1-3 of the conventional sewage interception well, after the upstream combined drainage ditch 101 enters the sewage interception well for interception, it passes through the overflow pipe 103 to the downstream sewage treatment plant; through the sewage interception pipe 102, the inspection well is used for regular inspections, etc. . The sewage interception well is not combined with the construction of the pipe gallery. If the rainwater and sewage diversion is completed upstream, the sewage interception well cannot be partially transformed to realize the combination of rainwater wells and sewage wells. It cannot meet the requirements of inspection wells after diversion of rainwater and sewage.

In view of the above situation, combined with the policies of protecting the water environment and advocating the transformation of confluent pipelines, etc., which are currently being promoted by the country, this utility model proposes a pipe gallery structure combining sewage interception wells and comprehensive pipe gallery.

Utility model content

Based on the above background technology, the utility model provides a structure combining rainwater and sewage diversion and pipe gallery. In order to solve the problem of rainwater and sewage diversion in the old urban area while constructing the pipe gallery, the sewage interception well and the drainage cabin of the pipe gallery are jointly constructed. In this structure, when the upstream pipeline has not been transformed into rainwater and sewage diversion, the sewage is diverted through the sewage interception well. If the upstream pipeline completes the rainwater and sewage diversion, the sewage interception well can be transformed into an independent rainwater well and sewage well. Realize the real diversion of rainwater and sewage. Gravity flow sewage pipes, pressurized sewage pipes and rainwater are arranged in the same cabin.

In order to achieve the above object, the utility model adopts the following technical solutions:

More and more drainage pipes are included in the pipe gallery. The height of other cabins in the pipe gallery is generally more than 3 meters. A separate rainwater or separate sewage pipe occupies a cabin, which is a waste of space. In the conventional drainage design, the buried depth of rainwater is generally shallow, and the elevation of sewage pipes is relatively deep. Combined with this feature, the utility model uses the upper part of the drainage chamber as a rainwater chamber, and the lower part is provided with sewage pipes. If the upstream is currently a confluence pipe, that is, if the diversion of rainwater and sewage has not been completed, the upstream confluence pipe will be connected to the sewage well during the dry season, and the drainage will flow into the sewage pipe.
