Construction method of river bottom regulation and storage channel box

Abstract

The invention discloses a construction method of a river bottom regulation and storage channel box. A construction area is demarcated on a river bottom, two groups of cofferdam walls are built at intervals on the demarcated construction area and extended in the flow direction of the river, and two support rods are arranged between the cofferdam walls, with each end connected with a cofferdam wallaside, thereby blocking the upstream and the downstream of the cofferdam walls and forming a working space between the cofferdam walls. The water in the working space is pumped out, and the working space is excavated. A through-flow section is built with reinforced concrete, the backfill is piled above the through-flow section, and the support rods and the cofferdam walls are removed. Arranging the through-flow section on the river bottom can greatly reduce the occupation of the land along the river banks, the influence on the residents and the factories along the river banks, and the projectcost by avoiding the complicated pipelines originally arranged along the river banks. The construction method of the through-flow section in the construction method can avoid river closure, and has the advantages of short construction period and low cost. The construction method is used to treat black and odorous water.

Description

technical field [0001] The invention relates to the field of underground water pipelines, 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, and due to historical reasons, there are often residential buildings and factories on both sides of the river, and the construction of wat...

AI Technical Summary

Problems solved by technology

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