Flexible multifunctional gutter inlet sewage intercepting bag and catch basin

Abstract

The invention discloses a flexible multifunctional gutter inlet sewage intercepting bag and a catch basin, and relates to the technical field of drainage. Comprising a flexible sewage intercepting bag which is mainly made of fabric, and the sewage intercepting bag is composed of a flow guide area, an overflow sewage intercepting area and a sediment filtering storage area which are connected in sequence. The diversion area is provided with an inclined diversion surface, and the bag opening is provided with a reinforcing ring; a plurality of overflow ports are formed in the circumferential direction of the overflow trash holding area; the end, away from the overflow trash holding area, of the sediment filtering storage area is closed. The sewage intercepting bag is installed in the catch basin through a hanging part arranged on the inner wall of the catch basin or the rainwater grate. The sewage intercepting bag can efficiently intercept various pollutants and reduce non-point source pollution while the water passing capacity of the gutter inlet is ensured; clogging of the drainage system is prevented, and dredging workload is reduced; mosquitoes and flies are prevented from breeding, and urban environmental sanitation is improved. The method can be used for construction of various types of gutter inlets and transformation of existing gutter inlets, and then a novel method which is simple, convenient, practical, efficient in operation and low in cost is provided for construction management of the gutter inlets.

Description

technical field [0001] The invention relates to the technical field of environmental protection and outdoor drainage engineering, in particular to a flexible multifunctional rainwater intercepting bag and a rainwater well. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The rainwater outlet refers to the water inlet structure that the outdoor drainage pipe collects rainwater on the ground. It is generally a well with a water inlet grate, which is used for outdoor drainage projects such as municipal roads, squares, and residential areas. Before entering the storm water outlet, the rainwater flows through the roof and the ground, forming surface runoff, washing away the accumulated garbage, soil, dust, oil, organic matter, heavy metals and other pollutants on the surface, and then carrying the pollutants into the drainage pipes through the ...

AI Technical Summary

Problems solved by technology

However, the existing technical solutions mainly have the following problems: 1. The main structure of the sewage interception and its fixing device is generally made of rigid materials or partly made of flexible materials, or the structure is too simple, the function is single, and the sewage interception effect is very poor; Either it is composed of complex structures and devices, but it can only remove certain pollutants or the removal efficiency is low, and the pollution interception effect is not satisfactory

2. It is difficult to balance the functions of sewage interception and drainage, and the drainage capacity of the rainwater outlet is affected to a certain extent, which affects drainage safety

3. It is inconvenient to install, disassemble, transport, clean up and maintain sewage interception and its fixing devices, and the overall cost or maintenance cost is relatively high

[0006] Among them, some technical schemes adopt sewage intercepting devices such as sewage intercepting baskets, trash racks, sewage intercepting net pockets, and filter net pockets. Due to the unreasonable shape and opening method of the main structure of sewage interception, when rainwater flows through, only coarse floating objects can be treated. For interception, fine particles and oil pollution and other pollutants are easy to penetrate the interception device, and the interception capacity is low

Part of the technical scheme uses complex suspension isolation devices, diversion devices, overflow devices and sewage interception devices such as sedimentation and filtration to combine. The structure is generally composed of rigid or flexible components. It is difficult to balance the effects, and it is very inconvenient to install and clean

At the same time, the existing technical solutions generally do not have enough storage space for pollutants, and water blocking is prone to occur with the accumulation of pollutants

[0007] The existence of the above problems has seriously restricted the popularization and application of existing technical solutions, making the problem of rainwater management a pain point and difficulty in the operation and maintenance of urban drainage systems and water ecological environment management.
