Abstract

The drainage holes of rainwater covers that are common in cities are relatively wide, causing leaves, sand, branches, paper scraps, small stones, etc. to directly enter the drainage pipes. Partial or even complete blockage of drainage pipes will result in poor water flow leading to urban waterlogging and waterlogging. The invention utilizes that substances with a specific gravity larger than water can settle in water, and substances with a specific gravity smaller than water can float on the water surface. A barrel-shaped object can be designed to settle the specific heavy substances at the bottom of the barrel. In order to reduce the floating matter entering the drainage pipe, the drainage hole is designed to be inclined upward by 45 degrees. In order to prevent the rainwater retained in the barrel from breeding mosquitoes, flies and other pests, a water seepage hole inclined at 45 degrees is designed at the bottom of the barrel.

Description

a sludge bucket

technical field

The design of the sedimentation bucket of the present invention relates to the field of municipal construction, in particular to drainage engineering. the

Background technique

The drainage holes of rainwater covers that are common in cities are rectangular, and the rectangles are 20-30 mm 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 up 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 fine, it will act as a sealant. The strength of the debris and the compactness of the sediment will make the drainage Some or even all of the pipes are blocked, so that the water flow is not smooth, resulting in water accumulation in the city, causing waterlogging. the

Contents of the invention

Waterlogging in some cities is often caused by the entry of leaves, sand, branches, paper scraps, small stones, etc. into drainage pipes, so avoiding or reducing their entry into drainage pipes can reduce the risk of waterlogging. the

The design scheme of the present invention's sedimentation bucket is: the material with a specific gravity larger than water can gradually settle in the water, and the material with a smaller specific gravity than water will float on the water surface, and the material floating on the water surface is generally relatively large, and a bucket-like The objects with large specific gravity will be settled at the bottom of the barrel. In order to reduce the floating matter entering the drainage pipe, the drainage hole is designed to be inclined upward at 45 degrees. the

The beneficial effect of the design of the sedimentation bucket of the present invention is that by reducing the entry of sediment and floating objects into the drainage pipes and avoiding the entry of larger objects into the drainage pipes, the burden on the sedimentation wells of the drainage pipes is reduced, the blockage of the drainage pipes is reduced, and the risk of urban waterlogging is reduced . the

specific implementation plan

Fix the sediment bucket on the drainage pipe under the rainwater cover, or it can be designed as a rectangle to keep consistent with the shape of the pipe. The edge (1) of the barrel is fixed under the rainwater cover, and the rainwater enters the sedimentation bucket (2) through the rainwater cover. Most of the silt, metal, stones, etc. that have a higher specific gravity than water will sink to the bottom of the barrel. The water seepage hole (7) at the bottom of the bucket is relatively small, designed to have a diameter of 1mm. The purpose is that when there is no incoming water, the remaining water in the bucket will slowly seep into the drainage pipe through the water seepage hole (7), so as to avoid depositing a certain amount of water in the bucket and thus breeding Mosquitoes, flies and other harmful organisms. When the water level in the bucket reaches the drain hole 6, the water will flow into the drain pipe through the drain hole 6. The drain hole 6 is designed to have a diameter of 2 mm and is inclined upwards at 45 degrees. After the drain hole is tilted, only the water surface is higher than the drain hole. It can be excluded, which can reduce the floating objects in the water to enter the drain hole (6). When the rainwater is heavy, or the sediment deposit has blocked the drainage hole (6), the water level rises to the drainage hole (5), and the water is discharged through the drainage hole (5). 45 degrees to reduce floating objects into the drain. When the rainwater is heavy, or the sediment deposit has blocked the drainage hole (5), the water level rises to the drainage hole (4), and the water is discharged through the drainage hole (4). The design diameter of the drainage hole (4) is 8mm, which further improves the drainage speed. Inclined at 45 degrees to reduce floating debris entering the drain. When the rainwater is heavy, or the sediment deposit has blocked the drainage hole (4), the water level rises to the drainage hole (3), and the water is discharged through the drainage hole (3). The downward slope is 45 degrees. After the sediment is deposited at this position, it will no longer accumulate but will be washed directly to the drainage pipe, so that the sediment bucket will not be able to drain due to the sediment accumulation blocking the drainage hole and causing waterlogging. the

When there is less silt in the sediment bucket and the inflow of water is large, all the drainage holes under the water surface will participate in the drainage to improve the drainage speed. the

The sedimentation bucket should be inspected at a certain time to remove the silted sediment and other sundries to ensure its normal function. the
