Description

Cistern

technical field

The utility model relates to the technical field of municipal water supply and drainage pipeline equipment, in particular to a water storage tank.

Background technique

The overflow pipe of the cistern is a device that must be installed in the cistern, and it is a measure to ensure the safe operation of the cistern. When the pool is full and the water intake is greater than the water output, the excess flow will be released from the overflow pipe to prevent the top plate from bearing the supporting force. The diameter of the overflow pipe is generally the same as that of the water inlet pipe, and the end of the pipe is a bell mouth, and no valve shall be installed on the pipe. In order to meet the anti-floating requirements of the reservoir, avoid direct sunlight on the top of the pond, keep the water temperature free from external influences as much as possible, and meet the heat preservation requirements, the top of the pond should be covered with soil; according to the national standard map-reservoir, the top of the pond should be covered with soil There are two types of thickness, 0.5m and 1.0m. In cold regions, it should be thickened appropriately according to the local frozen soil depth. The outlet of the pool overflow pipe is generally connected to the urban sewer system. In order to prevent reptiles in the sewer system from entering the pool along the overflow pipe, the standard diagram adopts that the overflow pipe first passes through the overflow well and then drains to the drainage well to avoid contamination of clean water.

In recent years, it is not uncommon for most cities in the country to experience waterlogging. Even if the design is in accordance with the national standard, the overflow weir in the overflow well is 0.3m higher than the ground. Over the overflow weir, pour back into the reservoir, pollute the clean water. In addition, for some reservoirs whose overflow water level is less than 0.3m above the design ground level, the possibility of being polluted by ground rainwater is greater. How to ensure that the clear water in the reservoir is not polluted by ground rainwater and ensure water quality safety has always been one of the key issues considered by the majority of engineering and technical personnel.
