Infiltrating road gutter inlet having secondary silt settling function

Abstract

The invention discloses an infiltrating road gutter inlet having a secondary silt settling function. The infiltrating road gutter inlet comprises a rainwater collecting and primary settling well and a silt settling and inflating well, wherein the rainwater collecting and primary settling well and the silt settling and inflating well are arranged in an adjacent mode and the silt settling and inflating well is deeper than the rainwater collecting and primary settling well; a primary collecting device is movably arranged in the rainwater collecting and primary settling well; a secondary collecting device is movably arranged in silt settling and inflating well; a cover plate, which is provided with a rainwater grate, is arranged on the top side of the rainwater collecting and primary settling well; a well cover, which is free from a rainwater grate, is arranged on the top side of the silt settling and inflating well; the upper side of the rainwater collecting and primary settling well is connected to the upper side of the silt settling and inflating well by virtue of a communicating pipe; an overflow pipe, which communicates with a road rainwater inspection well, is arranged at the upper side of the silt settling and inflating well; a secondary filtering section and a secondary silt settling section are arranged on the lower section of the silt settling and inflating well sequentially from top to bottom; and an inflating pipe, which is connected to surrounding soil bodies, is arranged on the secondary filtering section. The gutter inlet provided by the invention can effectively reduce emission pressure of a road rainwater main pipe and relieve or avoid the occurrence of road basement settlement and waterlogging phenomenons; and the technology for forming the gutter inlet is mature, convenient to construct and easy for daily maintenance.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a permeable road storm water outlet with the function of secondary sedimentation. Background technique [0002] With the vigorous advancement of urbanization, the area of ​​hardened ground has also increased significantly. Most of the rainwater on the hardened ground adopts organized drainage, that is, the ground rainwater flows to the rainwater outlet in an organized manner, and the rainwater outlet collects ground rainwater and flows to the rainwater inspection well through pipes. The inspection well drains rainwater to designated areas such as river channels through the rainwater main pipe. However, due to the extremely low infiltration rate of rainwater on the hardened ground, and the limited discharge capacity of the pipes and outlets that discharge rainwater, waterlogging often occurs in towns and cities. In order to solve urban waterlogging, improving the in...
