Broken line type dam joint structure and construction method thereof

Abstract

The invention relates to a broken line type dam joint structure and a construction method thereof. The invention is aimed at solving the technical problem of providing a broken line type dam joint structure and a construction method thereof to solve the problem of designing the dam joint structure under conditions of urban drainage pipes embedded in side slopes, a large area of dwelling houses, man-made slag heaps, small tributary import and the like in accordance with the requirements of structural stress, basic seepage prevention and seepage around the dam of the dam joint structure. For solving the problem, the method adopts a technical proposal that: the broken line type dam joint structure comprises dam concrete gate piers, built bridge concrete piers, a road masonry retaining wall and a built road, and is characterized in that a concrete retaining wall is built between the dam concrete gate piers and the concrete piers, that each structural seam of the concrete retaining wall is sealed by a waterproof sheet copper and that the inner side of the road masonry retaining wall, one end of the concrete retaining wall and one end of the built road have concrete thorn walls. The broken line type dam joint structure and the construction method thereof are applicable to water conservancy and hydropower projects and urban flood control projects.

Description

technical field [0001] The invention relates to a broken-line dam joint structure and a construction method thereof. It is suitable for water conservancy and hydropower projects and urban flood control projects. Background technique [0002] The structural design of dam joints in water conservancy and hydropower projects plays a very important role in engineering safety. Generally, the structural foundation of the dam joint is directly inserted into the bedrock surface of the bank, which can better meet the requirements of dam foundation seepage prevention and seepage around the dam. However, in the case of construction of pivotal projects near cities or counties, the shore conditions are extremely complex, and it becomes very difficult to design conventional dam joint structures, such as urban sewage pipes buried in the slope, large residential houses, and artificial slag piles In the face of such shore and foundation conditions, not only the construction is difficult, bu...

Problems solved by technology

[0003] In order to overcome the difficulties in the design of the dam joint structure under complex slope conditions, the present invention proposes a broken-line dam joint structure and its construction method to solve the problem of urban sewage pipelines, large residential houses, artificial slag piles, and small dam joints buried in the slope. Difficulties in the structural design of dam joints such as tributary confluence, to meet the requirements of dam joint structure stress, foundation anti-seepage and seepage around the dam
