Description

Technical Field

[0001] The utility model embodiment relates to the technical field of drainage wells, and in particular to a drainage well structure for a water supply network. Background Art

[0002] The pipeline system for delivering and distributing water to users in water supply projects is also called water supply network. It includes water delivery canals, water distribution networks, booster pump stations, water towers, pools and network ancillary facilities. The canals from the water source to the water plant only serve to deliver water, which is called water delivery network. The layout of the water network has two basic forms: branch and ring. The former has distinct main pipes and branch pipes, forming a tree-like shape; the latter has pipes connected vertically and horizontally to form a ring. The water network is composed of many water pipes, and the water network is connected to a drainage well.

[0003] A sluice well is a facility used to discharge water, usually located in low-lying areas of a city to maintain the hygiene and health of the city; the working principle of a sluice well is to collect water from the sewer into the well and then discharge it into a natural water body through a drain pipe, which is usually located at the bottom of the well, which can effectively discharge water into a natural water body, thereby reducing pollution and water quality problems. The design and construction of a sluice well needs to take into account factors such as water quantity, water quality and environmental protection to ensure that it can effectively discharge water and protect the environment;

[0004] The above-mentioned drainage well structure is shown in a drainage well structure with prior art application number 202120285193.5.

The opening of the box is lower than the bottom of the inlet pipe, and a plurality of through holes are provided on the box. By setting a collecting box in the technical scheme, the sludge in the collecting box can be processed, thereby reducing the accumulation of sludge in the drainage well, which has the effect of reducing the accumulation of sludge in the drainage well.

[0005] However, the following problem still exists in this technical solution: this technical solution periodically cleans the impurities inside the box. If the cleaning is not sufficient or the impurities are not cleaned in time, the impurities will block the through holes, thereby preventing water from draining. Utility Model Content
