Earth and rockfill dam slope protection structure and construction method
The invention belongs to the technical field of earth and rockfill dam construction, and particularly relates to an earth and rockfill dam slope protection structure and a construction method. The slope protection structure comprises a dam body with a trapezoidal cross section, a special-shaped concrete protection slope with a trapezoidal cross section and a transition inverted filter material, and the transition inverted filter material is arranged between the dam body and the special-shaped concrete protection slope. According to the construction method, the length b of the lower bottom is calculated according to the length a of the upper bottom, the height c and the downstream side slope ratio n of the special-shaped concrete protection slope and the slope ratio m of a preset dam slope, the special-shaped concrete protection slope is cast in situ at the preset position according to the calculation result, the dam body is filled, and the transition inverted filter material is filled between the special-shaped concrete protection slope and the dam body; after the built dam body and the transition inverted filter material are as high as the cast-in-place special-shaped concrete slope protection, the previous construction procedure is repeated until the dam body construction is completed; and then the earth and rockfill dam protection slope is built by cutting the special-shaped concrete protection slope in the vertical direction according to a preset interval. The dam material waste is reduced, the dam body filling quality is ensured, and the construction progress is accelerated.
本发明属于土石坝建筑技术领域，具体涉及一种土石坝护坡结构及构造方法。本发明包括横截面为梯形的坝体、横截面为梯形的异形混凝土护坡和过渡反滤料；过渡反滤料置于坝体与异形混凝土护坡之间。本发明按异形混凝土护坡的上底长度a、高度c及下游侧坡比n及预设的坝坡的坡比m，计算出下底长度b，根据计算结果在预定位置现浇异形混凝土护坡、填筑坝体、在异形混凝土护坡与坝体之间填筑过渡反滤料；当修筑的坝体以及过渡反滤料与现浇的异形混凝土护坡同高后，重复前面的施工程序，直至坝体施工完成；之后按照预设间隔、沿上下方向将异形混凝土护坡割开的步骤筑成土石坝护坡。本发明减少了坝料浪费、确保了坝体填筑质量、加快了施工进度。
