Drainage structure system underdrain and underdrain structuring method of drainage structure system

Abstract

The invention provides a drainage structure system underdrain applied to the technical field of drainage structure systems. The invention also relates to an underdrain structuring method of a drainagestructure system. According to the drainage structure system underdrain, the underdrain channel (2) of every underdrain module (1) is in a U-shaped cross-sectional structure, the upper portion of every underdrain module (1) is connected in a fastened mode with an underdrain cover plate (3), the underdrain channels (2) of a plurality of the underdrain modules (1) form a drainage channel, underdrain parts are arranged inside arranging pits (7) formed in the ground (6), and a covering soil layer (8) is arranged above the underdrain cover plates (3). The drainage structure system underdrain and the underdrain structuring method of the drainage structure system can effectively combine the advantages of ditch drainage and pipe drainage, overcome the shortcoming of poor sanitary conditions of traditional drains, facilitate drain dredging, solve the problem of underdrain dredging inconvenience and reduce the construction difficulty.

Description

technical field The invention belongs to the technical field of drainage structure systems, and more specifically relates to a drainage structure system culvert, and the invention also relates to a drainage structure system culvert construction method. Background technique The design of the rainwater drainage system adopted in the prior art all has defects in varying degrees: 1. Pipeline drainage: pipeline drainage is composed of drainage pipes, inspection wells, rainwater outlets, and rainwater outlet connecting branch pipes. It is a semi-closed drainage system, but due to The characteristics of the system itself cause it to have some shortcomings that cannot be overcome: 1) Considering the impact of the pipeline load and freezing, the buried depth of the pipeline is required to be at least 0.7 meters, and there is a minimum slope limit for drainage. If the system is large, the downstream Pipeline burial will be very deep. Because the rainwater is a gravity flow, the eleva...
