Concrete dam section foundation pit drainage and dam foundation pouring method
The invention discloses a concrete dam section foundation pit drainage and dam foundation pouring method. The method comprises the steps of 1, construction preparation; 2, construction of a concrete dam section foundation pit drainage system; 3, dam foundation pouring of a concrete dam section and foundation pit drainage; and 4, backfill pouring of the concrete dam section foundation pit drainage system. The concrete dam section foundation pit drainage system is arranged for conducting water diversion type drainage on a dam section foundation pit, the water pumping and drainage position is fixed, the construction difficulty is effectively lowered, the construction progress is accelerated, meanwhile, the water accumulation problem of a foundation pit concrete pouring work face can be effectively relieved, cement paste losses during concrete pouring are reduced, and the dam foundation concrete construction quality is guaranteed; and in addition, after dam foundation pouring is finished, concrete backfill in the system is conducted, the dam foundation stability is guaranteed, the backfill effect is good, and usage and popularization are convenient.
本发明公开了一种混凝土大坝坝段基坑排水及其坝基浇筑方法，包括步骤：一、施工准备；二、混凝土大坝坝段基坑排水体系的施工；三、混凝土大坝坝段的坝基浇筑并进行基坑排水；四、混凝土大坝坝段基坑排水体系回填浇筑。本发明通过设置混凝土大坝坝段基坑排水体系对坝段基坑进行引水式排水，抽排水位置固定，在有效地降低施工难度、加快施工进度的同时能够有效缓减了基坑混凝土浇筑工作面的积水问题，减少混凝土浇筑时水泥浆的流失，以保证大坝基础混凝土施工质量，此外在大坝基础坝体浇筑完成后进行体系内部的混凝土回填，保证大坝基础的稳定性，回填效果好，便于推广使用。
