Embodiment Construction

[0026] like figure 1 , figure 2 , image 3 As shown, the present embodiment has the concrete pier 3 of the dam concrete pier 2, the built bridge, the road masonry retaining wall 5 and the built road 14, and the feature of the present embodiment is that the dam concrete pier 2 and the concrete pier 2 A concrete retaining wall 1 is set between the piers 3, and each structural joint of the concrete retaining wall is sealed by a water-stopping copper sheet 7; on the inner side of the road masonry retaining wall 5, one end of the concrete retaining wall 1 is connected to the built road 14 Concrete thorn wall 4 is set at one end.

[0027] In terms of water sealing, the structural joint between the concrete retaining wall 1 and the concrete pier 2 of the dam is treated with water sealing copper sheet 7. For the structural joints between the built bridge 15 concrete pier 3 and the concrete retaining wall 1 adopt mechanical structure sealing water treatment, see Figure 4 , the me...

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...
