Overlap joint device between water retaining curtains

Abstract

The invention discloses an overlap joint device between water retaining curtains, and relates to a curtain overlapping process for solving the problems in overlapping and fixing between adjacent water retaining curtains and the problem of water leakage, and the process refers to that curtains and anchor blocks are distributed in the edge positions of adjacent curtains in a staggered manner. The overlap joint device provided by the invention is used for water retaining below large scale water surfaces. The overlap joint device is composed of two curtains and two anchor blocks, the curtains are connected with the anchor blocks through two cables respectively, the curtains adopt water-stopping structures, the cables are connected with the curtains, and one ends of the cables are fixed on the anchor blocks. Adjacent curtains are overlapped in a crossing manner in edge positions, and the overlap joint between the curtains is achieved through the fixing of the anchor blocks and the cables. After the mounting, under the effect of water flow, the two curtains cling to each other mutually, no clearance is left, water flow passing is stopped, and the purpose of treating low temperature water is achieved. According to the process, no component is required to be added on the curtains, the construction is convenient and quick, the operation is simple, impacts on a power station putting into running are small, and construction and maintenance costs are low.

Description

Technical field [0001] The invention relates to a curtain lap process which can solve the problems of lap fixation and water leakage between adjacent water-retaining curtains. The curtains and piers are arranged alternately at the edge of adjacent curtains. Used for retaining water under large water surfaces. Background technique [0002] After the reservoir built on the river course is impounded, the water depth in the reservoir area will increase significantly, and obvious water temperature stratification will occur. Generally, the water temperature of the surface layer (water depth above 5m) changes significantly with air temperature; the water temperature of the bottom layer (water depth below 120m) is basically constant throughout the year between 8℃~10℃; the water depth between 5m and 120m is a variable temperature layer, of which 5m to 80m The gradient of water temperature change is relatively large in time, which is a thermocline, and the gradient of water temperature ch...
