Storm runoff desanding well of urban road
The invention discloses a storm runoff desanding well of an urban road. The device is composed of two parts including a vertical flow well (2) and an upper flow well (11), wherein the vertical flow well (2) is composed of a rainwater perforated strainer (1), an energy dissipation screen (3) and a sand hopper (4), the depth of the sand hopper (4) is 0.5 meter, inclined angles of four sides are 60 degrees, a sand level sensor (9) is installed on the top of the sand hopper (4), and a submersible sewage pump (10) is installed at the bottom of the sand hopper (4); the upper flow well (11) is composed of four parts including a clean water area (8), a filter layer (7), a water distribution area (6) and a two-phase separating area (5), and the bottom of the upper flow well (11) is of an inclined structure at an inclined angle of 30 degrees; the depth of the filter layer (7) is 0.5 meter and is formed by limestone with the particle size of 30 mm; the depth of the two-phase separating area (5) is 0.5 meter and is formed by five layers of stainless steel triangular plates at an inclined angle of 45 degrees. The storm runoff desanding well mainly has the following advantages that the sand trapping efficiency is high; the application is flexible, and the present situation of a pipe network is not influenced; while trapped sand is removed, back flush can be synchronously and automatically performed by the filter layer (7).
