Dam section foundation pit drainage and dam foundation pouring method for concrete dam
The invention provides a concrete dam section foundation pit drainage and dam foundation pouring method applied to the field of dam manufacturing. The concrete dam section foundation pit drainage and dam foundation pouring method specifically comprises the following steps that S1, drainage ditches are arranged; s2, multiple sets of auxiliary water collecting wells and main water collecting wells are arranged; s3, a steel sinking cylinder is arranged in the main water collecting well, a water pumping system is further arranged in the foundation pit and comprises a water pump, a drainage pipe is arranged at the output end of the water pump, and an impurity removing mechanism and a water pressing mechanism are further arranged on the drainage pipe; according to the method, impurities are automatically separated through water flow impulsive force generated when the water pump operates, the water pressing mechanism is driven by buoyancy of a balancing weight to move up and down as a whole, the phenomenon of empty suction of the water pump is effectively prevented, the water pumping service life of the water pump is prolonged while energy consumption is reduced, and the service life of the water pump is prolonged. And the water drainage efficiency of the foundation pit of the dam section of the concrete dam is improved.
本发明提供了应用于大坝制造领域的一种混凝土大坝坝段基坑排水及其坝基浇筑方法，具体包括以下步骤：S1、设置排水沟；S2、设置多组副集水井和主集水井；S3、在主集水井内设置钢沉筒，基坑内还设置有泵水系统，泵水系统包括水泵，水泵的输出端设有排水管，排水管上还设有除杂机构和压水机构；S4、利用压水机构和除杂机构，完成基坑排水动作，本申请利用水泵运行时的水流冲力自动分离杂质，利用配重块的浮力驱动压水机构整体上下位移，有效防止了水泵出现空吸的现象，达到降低能耗的同时，增加了水泵泵水寿命，提升了混凝土大坝坝段基坑的排水效率，具有市场前景，适合推广应用。
