AI Technical Summary
In existing drainage wells, debris such as leaves smaller than the mesh size of the drainage grate can easily enter the well and accumulate in the drainage pipe, leading to difficulties in cleaning and high costs.
The system adopts a double-layer drainage grate design. The aperture of the first drainage grate is larger than that of the second drainage grate. The second drainage grate is embedded in the lower surface of the first drainage grate or is spaced apart from it. It is fixed with the angle iron connector by nuts to form a double-layer filtration structure.
It effectively intercepts leaves and other debris smaller than the aperture of the first drainage grate, preventing them from entering the well and accumulating, thus reducing the trouble and cost of later cleaning.

Abstract
Description
Technical Field
[0001] This utility model relates to water collection wells, specifically to a prefabricated water collection well that is easy to maintain. Background Technology
[0002] The existing drainage wells along the edges of the green lawns use single drainage grates for filtration to intercept the water flowing into the wells. However, leaves and other debris smaller than the drainage holes of the grates can also enter the wells through the drainage holes and then accumulate in the drain pipes as the liquid flows. Over time, this accumulation in the drain pipes makes cleaning quite tedious. We hope to find a good solution to this problem. Utility Model Content

[0032] It should be noted that, in the embodiment, the angle iron connector 2 is inserted into the cross section of the port of the precast concrete well body 1 before the precast concrete well body 1 has been poured and solidified, and forms a whole after solidification.
[0033] Furthermore, the above embodiments also include a first drainage grate 3 and a second drainage grate 4, and the radius of the drainage channel hole of the first drainage grate 3 is not less than twice the radius of the drainage channel hole of the second drainage grate 4.
[0034] Furthermore, in the above embodiment, the first drainage grate 3 is a cast iron plate, and the second drainage grate 4 is a cast iron part. The second drainage grate 4 is structurally divided into a support portion 41 and an isosceles trapezoidal body 42. The lower base of the isosceles trapezoidal body 42 is connected to the support portion 41, and the length and width of the lower base of the isosceles trapezoidal body 42 are equal to the length and width of the inner ring of the staggered platform in the planar state. The isosceles trapezoidal body 42 has a recessed structure, and the port of the recessed structure faces the first drainage grate 3. The support portion 41 has a rectangular ring structure, and the inner ring of the rectangular ring structure is connected to the interior of the recessed structure of the isosceles trapezoidal body 42.
