Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] Such as figure 1 figure 2 and image 3 The shown seamless water-stop face dam includes a coplanar concrete support surface formed by extruded side walls 1 and plinth 2 and an integral water-stop layer 3 arranged on the concrete support surface. A surface protective concrete panel 4 is arranged on the waterproof layer 3 , and a cover plate of the toe board 2 is arranged at the toe board 2 .

[0017] This application abandons the seam sealing scheme that has been used in the prior art, and adopts a "sandwich structure" in which an integral water sealing is provided between the concrete panel and the extruded side wall 1, fully utilizing the advantages of different materials, and eliminating the gap between the panels. The vertical joints and the peripheral joints between the panel and the plinth improve the integrity of the water stop system, simplify the construct...

Abstract

The invention discloses a seamless water-stopping panel dam and particularly discloses the seamless water-stopping panel dam which relates to the field of water-power engineering panel dam construction. The seamless water-stopping panel dam comprises a coplanar concrete supporting face and an integral water-stopping layer, wherein the coplanar concrete supporting face is composed of an extrusion side wall and toe boards, the integral water-stopping layer is arranged on the concrete supporting face and is provided with a surface layer protection concrete panel, and toe-board cover boards are arranged at the toe boards. According to the seamless water-stopping panel dam, by means of a sandwich structure formed by the concrete panel, the water stopping and the extrusion side wall, a seamlessand integral water-stopping panel is formed, the water leakage risk of the panel is lowered, and the difficulty of the panel in design, seam splitting, construction and maintenance is lowered; and theflexible water stopping is integrally seamless, as long as the connection with the toe board is properly handled, the ability of a sandwich panel to adapt to deformation is also relatively strong.

Description

technical field [0001] The invention relates to a seamless water-stop face dam, in particular to a seamless water-stop face dam in the field of hydropower project face dam construction. Background technique [0002] Among the existing water conservancy and hydropower damming technologies, face rockfill dams are widely used because of their good adaptability to topographic and geological conditions, small dam body cross-section, and good economy. Existing face dam construction technology mainly adopts reinforced concrete face plate, vertical joints, and the anti-seepage of the dam body is mainly composed of reinforced concrete face plate and joint water stop. Seam seals generally include peripheral seams and vertical seams, and top water seals, inter-seam water stops, and bottom water seals are set according to the displacement of the seams. The design and construction quality of the water stop are directly related to the anti-seepage and seepage safety of the dam body. At t...
