Construction method of shallow tunnel integrated system for improving quality of water environment

Abstract

The invention discloses a construction method of a shallow tunnel integrated system for improving the quality of the water environment. A river bottom is involved, a surge bottom regulation and storage channel box is arranged below the river bottom, an upper joint and a lower joint of the surge bottom regulation and storage channel box are located in high positions, and a sewage flowing port in the middle of the surge bottom regulation and storage channel box is located in a low position so that sewage can naturally flow into the surge bottom regulation and storage channel box. A water delivering pipe of an underground overlapping dual-pipeline co-well structure can deliver water of the sewage flowing port to a sewage treatment plant, and a water conveying pipe can send the treated water back to the midstream of a river. A through-flow section is arranged below the river bottom, and in this way, the land occupation area can be greatly reduced; meanwhile, since upper pipe sets constituting the water conveying pipe and lower pipe sets constituting the water delivering pipe are formed by construction in the same excavating well, the construction time can be greatly shortened, the occupied area of two banks along the river is reduced, and the enclosure area of a road is small, and the influence on the life of residents along the river is small. A coffer wall is adopted for waterproof isolation, various negative influences brought by closure can be avoided, and the method is used for treatment of black and odorous water.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to the field of treatment of black and odorous water bodies in rivers. Background technique [0002] Urban water bodies refer specifically to rivers, lakes, reservoirs and various landscape water bodies within the urban radiation range. As the carrier of the environment and an important resource, rivers have shown irreplaceable significance in the ecological construction of cities and the expansion of economic development space. On the one hand, it has the functions of water quality conservation and water and soil conservation, and on the other hand, it also plays a positive role in improving the urban microclimate and the living environment of residents. [0003] River management is often supported by government financial allocations. Due to historical reasons, there are often residential buildings and factories on both sides of the river.

Problems solved by technology

[0003] River management is often supported by government financial allocations. Due to historical reasons, there are often residential buildings and factories on both sides of the river. When building water conservancy facilities, a large amount of land needs to be occupied, which involves land acquisition, The problem of road enclosure construction, the culvert scheme adopted by the existing technology, the land acquisition and enclosure area is large, which brings huge pressure on finances and has a great impact on the lives of residents along both sides of the river

[0004] Due to various reasons, such as the high cost of land acquisition in the downstream, and the construction of sewage treatment plants in the middle reaches of the river in the early years, it is no longer possible or suitable for the construction of sewage treatment plants in the downstream, which will lead to the inability of the downstream of this river section. Complete the treatment of black and odorous water bodies
