Common sewage-interception hanging basket and mounting method

Abstract

The invention discloses a common sewage-interception hanging basket and a mounting method. The common sewage-interception hanging basket comprises a sewage-interception hanging basket body, a rectangular opening is formed in the top of the sewage-interception hanging basket body, and a long edge of one side of the rectangular opening corresponds to a long edge curved surface side wall; a long edgeof the other side corresponds to a long edge plane side wall, and the side walls, corresponding to the two short edge sides, of the rectangular opening are short edge plane side walls; the bottoms ofthe long edge curved surface side wall, the long edge plane side wall and the short edge plane side walls are connected to a basket bottom; vertical drainage holes are formed in the long edge plane side wall and the short edge plane side wall, no hole is formed in the middle of the long edge plane side wall, and a vertical drainage hole is formed in the upper portion of the long edge plane side wall; a water draining hole is formed below each drainage hole. According to the hanging basket, the rainfall runoff impurities can be effectively intercepted, and the large-grain-size solid suspensionsubstances are precipitated; a buckle device and a plug device are arranged at the outer edge of the top of the sewage-interception hanging basket, and the sewage-interception hanging basket can be conveniently fixed to the lower portion of a rainwater grate and is convenient to detach, clean and maintain and suitable for all types of rainwater ports.

Description

technical field [0001] The invention relates to the technical field of rainwater interception and sewage, in particular to a general-purpose sewage interception hanging basket and an installation method. Background technique [0002] A large number of research results show that urban non-point source pollution is the main source of pollutants in urban construction areas, and the concentration of pollutants in road rainwater runoff generally exceeds the national surface water environmental quality standard V, and is even far higher than the concentration of urban sewage. In addition, due to the randomness and extensiveness of urban non-point source pollution, the reduction and control of urban non-point source pollution has become a major problem restricting the improvement of urban water environment and water ecological quality. The stormwater outlet is the entrance for the surface runoff to enter the stormwater pipeline, and it is also an important link in the control of th...

Problems solved by technology

[0004] The invention patent with the application number CN200810112073.4 discloses an environment-friendly stormwater outlet filter bucket; the sewage intercepting hanging basket is fixed inside the stormwater outlet by placing an additional bracket at the bottom. There are two main problems in this method: one is Due to the differences in the internal size and shape of different rainwater outlets, the size of the sewage intercepting hanging basket must be customized separately, so the versatility is insufficient; the second is that the structure, material, size and connection method of the bracket are not given, and the degree of standardization is low, and Machining and installation of brackets will add extra work

[0005] Moreover, the bottom of the sewage intercepting hanging basket has no holes, so it has the effect of sedimentation in the rainwater runoff, but since there is no discharge outlet for the runoff, after the rainfall ends, a part of the rainwater runoff will be stored at the bottom, causing the water body to deteriorate and breed Problems such as mosquitoes can easily cause secondary pollution

In addition, most of the similar sewage intercepting hanging baskets have holes at the bottom. Although there is no series of problems caused by the later storage of rainwater runoff, it also loses the sedimentation effect

[0006] It can be seen that most of the existing sewage intercepting hanging baskets are part of the environmental protection gullies, designed and processed together with the environmental protection gullies, and fixed inside the gullies. Poor versatility, not suitable for the renovation needs of existing rainwater outlets

Moreover, most of the existing sewage intercepting hanging baskets have openings at the bottom, which can only filter large-sized debris. Functionally, it is only an enhancement of the filtering effect of rain grates, and lacks the filtration and precipitation of small-sized pollutant particles. effect
