Water retaining dam structure

Abstract

The invention discloses a water retaining dam structure. The water retaining dam structure is characterized in that concrete column piers are arranged by every other 4-6 m; concrete arch plates are arranged between the adjacent concrete column piers; the concrete arch plates adopt precast slabs; T-shaped ribs are embedded in the concrete arch plates; water leakage holes are formed in the concrete arch plates; concrete arch beams are arranged on the concrete arch plates; the outer sides of the concrete arch beams are leveled with the outer sides of the concrete arch plates; backing columns are arranged from the concrete column piers by 0.8-1.1 m; continuous walls are arranged between the concrete column piers and the backing columns, and are vertically provided with concrete continuous beams by every other 1.5-2.5 m; backing walls are arranged between the adjacent backing columns; the backing walls are built by adopting blocks or bricks; the backing columns and the backing walls are connected by tension ribs; the backing walls are vertically provided with backing wall beams by every other 1.5-2.5 m; multiple rib walls are arranged between the backing walls and the concrete arch plates; the rib walls and the concrete arch plates are connected by T-shaped ribs; the rib walls are vertically provided with concrete rib beams by every other 1.5-2.5 m; and sandy soil or clay is filled between the concrete arch plates and the backing walls.

Description

technical field [0001] The invention relates to a retaining dam structure and relates to the field of water conservancy. Background technique [0002] Traditional retaining dams are excavated to the bottom and then poured concrete or masonry retaining walls. This method is prone to earthwork collapse during construction. If the construction is to be smooth, a special support structure is required. If no special support structure is used, it will obviously save a lot of cost and shorten the construction period. In addition, the cost of traditional gravity retaining dam is relatively high. Therefore, if a reasonable retaining dam structure can not only ensure safety but also save cost, it is a problem faced by engineering personnel. Contents of the invention [0003] The invention provides a water retaining dam structure, which solves the problems of earthwork collapse and high engineering cost during the construction process of the water retaining dam. [0004] In the pr...
