Embodiment Construction

[0009] specific implementation plan

[0010] The water inlet hole (1) with a diameter of 2 mm in the sedimentation nest is designed to have a diameter of 2 mm and a hole spacing of 4 mm. The drainage holes are designed into 2 types: the lower part is designed with multiple rows of drainage holes with a diameter of 2mm, which are inclined upward at 45 degrees (3), and 1-2 rows of drainage holes with a diameter of 3 mm are designed near the top, inclined at a downward angle of 45 degrees (2), the number of drainage holes Determined according to the area of ​​the drainage surface of the sediment nest.

[0011] Due to the small aperture of the water inlet hole (1) with an aperture of 2mm, relatively large debris (such as leaves, branches, stones, etc.) can be prevented from entering the mud nest, and substances with a specific gravity heavier than water in the mud nest will gradually settle in the mud nest (5) At the bottom, the rainwater passes through the drainage hole with a d...

Abstract

In cities, an outlet of a common rainwater cover is larger, and a large quantity of leaves, twigs, small stones and paper scraps, a large amount of sludge and the like enter a water drainage pipeline to make one part or all parts of the water drainage pipeline plugged, so water logging occurs. In the design for the sludge deposition nest, rainwater enters the water drainage pipeline through the sludge deposition nest instead of entering the water drainage pipeline directly after the sludge deposition nest deposits partial substances heavier than water and filters other impurities. In the design, a water inlet hole with the aperture of 2 millimeters, a water drainage hole which is inclined downwards 45 degrees and has the aperture of 3 millimeters, a water drainage hole which is inclined upwards 45 degrees and has the aperture of 2 millimeters, and a water seepage hole which is inclined 45 degrees and has the aperture of 1 millimeter.

Description

technical field [0001] The design of the sludge nest of the present invention relates to the field of municipal construction, in particular to drainage engineering. Background technique [0002] The drainage holes of rainwater covers that are common in cities are rectangular, and the rectangle is 20-30mm wide. The main problem is: leaves, silt, twigs, paper scraps, small stones, etc. can enter the drainage pipe from the drainage hole. Although sedimentation wells are set at certain distances in the drainage pipes, the sediment will not completely settle in the sedimentation wells. Since the specific gravity of leaves, branches and other sundries is equal to that of water, the settlement effect is not good and may accumulate in the drainage pipes At a certain position, with the accumulation of debris in the drainage pipe, the subsequent sediment will further accumulate. Since the sediment is relatively small, it will act as a sealant, causing partial or even complete blockag...
