Combined and improved gutter inlet equipment

Abstract

The invention discloses combined and improved gutter inlet equipment. The combined and improved gutter inlet equipment comprises gutter inlet equipment bodies which are arranged in greenbelts on two sides of city roads and sidewalk areas in a scattered manner and are in open communication with peripheral hydrological systems and is characterized in that each gutter inlet equipment body comprises acatch basin, a filter layer, a settling basin, a discharge pipe and a buffer discharge outlet, the catch basin is used for collecting and distributing runoff rainwater, the filter layer is used for filtering and purifying the runoff rainwater, the catch basin, the filter layer and the settling basin are sequentially adjacently arranged and sequentially communicated, the settling basin is communicated into discharged water through the discharge pipe, the buffer discharge outlet is arranged at the outlet of the discharge pipe, and the width of the buffer discharge outlet is larger than the pipediameter of the discharge pipe. The combined and improved gutter inlet equipment is capable of supplementing underground water and surface water and capable of repairing the hydrological systems andrecycling rainwater.

Description

technical field [0001] The invention relates to a combined improved rainwater device, which belongs to the technical field of municipal engineering. Background technique [0002] my country is rich in water resources, but the per capita water resources are relatively low, and the geographical distribution is uneven, especially in large cities with a large population, and local water sources are far from meeting the needs of water for life and economic activities. Water resources have become a key issue in today's society. Rainwater, as a valuable water resource, has long been valued in developed countries. However, in my country, the concept of resource utilization of rainwater started relatively late. Most areas are still dominated by the concept of fast drainage, and rainwater resources have not been fully utilized. At the same time, the rapid discharge of runoff rainwater has led to the isolation of the connection between surface water and groundwater in the hydrological s...

[0002] my country is rich in water resources, but the per capita water resources are relatively low, and the geographical distribution is uneven, especially in large cities with a large population, and local water sources are far from meeting the needs of water for life and economic activities. Water resources have become a key issue in today's society

Rainwater, as a valuable water resource, has long been valued in developed countries. However, in my country, the concept of resource utilization of rainwater started relatively late. Most areas are still dominated by the concept of fast drainage, and rainwater resources have not been fully utilized. At the same time, the rapid discharge of runoff rainwater has led to the isolation of the connection between surface water and groundwater in the hydrological system, and groundwater cannot be replenished.

[0003] The current solution is to build rainwater purification and utilization facilities. After the runoff rainwater is treated, the groundwater will be replenished through infiltration, and the uninfiltrated rainwater will be discharged into the urban water body to replenish the surface water body, realize the resource utilization of rainwater, and restore the hydrological system. ; However, the cost of this solution is relatively high, and the treated rainwater is discharged in a centralized manner, which has a certain impact on the water quality of the receiving water body; while some decentralized treatment equipment only considers rainwater purification treatment, and the treated rainwater still enters the rainwater pipeline system. It cannot be consumed and utilized on the spot, and groundwater cannot be replenished, and the purified rainwater enters the rainwater pipeline, and there is a risk of secondary pollution
