Description

TECHNICAL FIELD

[0001] The present application relates to the field of municipal drainage, in particular to a pipe connection box culvert large drop water drainage system and method. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] In recent years, with the increasing improvement of drainage design standards, especially for urban main drainage channels, drainage box culverts are increasingly used in urban construction. Considering the pipeline integration and the adverse effects on future construction, the box culvert is generally buried deep. For flat terrain, the downstream box culvert is buried to a depth of 10 m or even more. For the land on both sides of the box culvert, the buried depth of the service land drainage reserved pipe is about 3 m. According to the outdoor drainage design standard, when the pipe drop water head is 1.0-2.0 m, a drop well should be provided; when the drop water head is greater than 2.0 m, a drop well should be provided; when the inlet pipe diameter of the drop well is not greater than 200 mm, the height of the one-time drop water head should not be greater than 6.0 m; when the pipe diameter is 300 mm-600 mm, the one-time drop water head should not be greater than 4.0 m, and the drop water method can be vertical pipe or rectangular tank; when the pipe diameter is greater than 600 mm, the height of the one-time drop water head and the drop water method should be determined according to the hydraulic calculation. In the rainy season, the direct large height difference drop water inlet will convert the gravitational potential energy into kinetic energy, which will impact the bottom of the box culvert. The high gravitational potential energy is converted into high flow kinetic energy, causing damage to the box culvert structure.

[0004] At present, the pipe connection into a large buried depth box culvert engineering measure is divided into two cases. One is that the rainwater inlet connecting pipe with a pipe diameter less than 500 mm generally does not consider drop water energy dissipation measures. The second is that the land reserved pipe with a pipe diameter of 500 mm and 600 mm and above generally solves the problem by increasing the buried depth of the land reserved inspection well and adding a drop water inspection well between the land reserved well and the box culvert. The inventor finds that the drop well methods include vertical pipe type, vertical tank type and ladder type. As the reserved pipe diameter increases, the construction difficulty and cost of the drop well increase. In addition, this method has many structures, occupies a large area, has a large buried depth of the pipe and structure, has a complex process, has a large construction difficulty, has a long construction period and has a high cost. The rainwater and sewage pipe culvert carries suspended solids and floating objects into the drop well and even the box culvert, causing impurities to deposit at the bottom of the drop well and even the box culvert. If the impurities are not dredged in time, they will be hardened. Since the drainage structure is buried deep, dredging is difficult, and the difficulty of later maintenance is great. SUMMARY
