Water conservancy project foundation pit tube well and light well point combined dewatering and drainage method
The invention provides a water conservancy project foundation pit tube well and light well point combined dewatering and drainage method, which belongs to the technical field of water conservancy projects, and comprises the following steps: considering waterproof boundary conditions around a foundation pit, establishing a water flow supply function, virtually arranging a plurality of light well points on the periphery of the foundation pit, and establishing a water flow loss function; the water flow supply function and the water flow loss function are combined into a complete calculation function of water flow connection inside and outside the pit; the number of the light well points needing to be arranged is calculated through the complete calculation function; calculating the deepest water level depth of the foundation pit and the burying depth of the suction well point of the foundation pit through a water seepage flow field function; calculating the number of pumping well points of the foundation pit based on the total water inflow; and carrying out dewatering and drainage system construction according to the number of the light well points, the number of the suction well points and the burying depth of the suction well points, so that the dewatering and drainage construction scheme of the water conservancy project meets the requirements of the optimization target.
本发明提出了水利工程基坑管井结合轻型井点降排水方法，属水利工程技术领域，考虑基坑四周的隔水边界条件，建立水流补给函数，在基坑外周边虚拟布置多个轻型井点，建立水流流失函数；水流补给函数和水流流失函数组合成为坑内外水流联系的完整计算函数；通过完整计算函数计算需要布置的轻型井点的数量；通过渗水流场函数计算基坑最深水位深度和基坑抽吸井点的埋设深度；基于总涌水量，计算基坑抽吸井点的数量；按照轻型井点的数量、抽吸井点的数量以及抽吸井点的埋设深度进行降排水系统施工，使水利工程的降排水施工方案满足优化目标的要求。
