Abstract

The water inlet of urban rainwater pipes is usually a rectangle with a width of 25-30mm. Due to its relatively large size, relatively large debris such as branches, leaves, and small stones can also enter the drainage pipe directly. The debris accumulates in a certain position of the drainage pipe, and then The accumulation of sediment may completely block the drainage pipe. Since sediment and other substances with a specific gravity larger than water are easy to settle, they are at the bottom of the water flow, and it is the force of the water flow that makes them move forward. Larger substances may be deposited in the rectangular box, thereby reducing the sediment entering the drainage pipe and reducing the burden on the sedimentation well of the drainage pipe.

Description

Mud box design

technical field

The design of the mud settling box of the utility model relates to the field of municipal construction, in particular to drainage engineering.

Background technique

The water inlet of urban rainwater pipes is usually a rectangle of 25-30 mm. Because it is relatively wide, relatively large debris such as branches, leaves, and small stones can also enter the drainage pipe directly, although the drainage pipes are equipped with sediment wells at certain distances. , but the sediment will not completely settle in the sedimentation well. Because the specific gravity of leaves, branches and other sundries is equal to that of water, the settlement effect is not good, and it is easy to accumulate in a certain position of the drainage pipe, and then the sediment continues to accumulate here , the strength of large debris plus the compactness of the sediment may completely block the drainage pipe.

Contents of the invention

The main purpose of the utility model is to reduce silt entering the drainage pipe.

The technical scheme of the utility model for sediment entering the drainage pipe is: because sediment and other substances with a larger specific gravity than water are easy to settle, they are at the bottom of the water flow, and it is the force of the water flow that prompts them to move forward. In the low-lying place, the sediment and other substances with a higher specific gravity than water may settle in the low-lying place, thereby reducing the sediment entering the drainage pipe.

The beneficial effect of the utility model is that because the sediment entering the drainage pipe is reduced, the burden on the sedimentation well of the drainage pipe is reduced, the risk of blockage of the drainage pipe is reduced, water and soil loss is reduced, and water quality is partially purified.

Description of drawings

Figure 1 is a schematic diagram of a sedimentation box.

Among them, 1, 10mm round holes, 2, 3mm round holes.

specific implementation plan

Design a rectangular box without a sealing cover. Since it is not sealed, in order to avoid pedestrians’ feet getting injured, the width should not be too large. The recommended box width is 25-30mm. If a relatively large rectangular box is required, a sealing cover with a grid must be added, and the grid size is preferably 25-30mm. Urban roads are generally designed to have a slightly lower edge. The sedimentation box is mainly placed on the edge of the road where rainwater flows, with a length of 150-200mm. Some road edges are paved with strip cement blocks. In this case, the length can be consistent with the width of the cement block. Two 10mm round holes (1) are used to hang the hook to take out the sediment box, and the 3mm round hole (2) is located at the bottom, the function is to infiltrate the water trapped in the box into the ground after the rain stops, so as to keep the sediment in the box relatively Dry to avoid breeding mosquitoes, flies and other pests.

Claims (1)

1. The sedimentation box is a rectangular box, its features are: width 25-30mm, length 150-200mm; two 10mm round holes; 3mm round holes at the bottom.
