Low-influence foundation pit excavation equipment and method
The invention discloses a low-influence foundation pit excavation device and method, and relates to the technical field of foundation pit excavation, the low-influence foundation pit excavation device comprises a moving trolley, the top of the moving trolley is fixedly connected with a first pump, and one end of the first pump is provided with a suction pipe. A first rotating roller and a second rotating roller can rotate at set intervals, so that a filter screen is wound on the outer side of the second rotating roller, then an inlet pipe and a switch valve corresponding to the second rotating roller are opened, a second pump machine discharges clean water into a rotating joint, the clean water enters a driving box through a hose, and the clean water enters a liquid cavity through the opened inlet pipe; the water is sprayed to the outer side of the filter screen through the spraying pipe, when water flows into the inlet pipe in the driving box, the water pushes the fan blades to move, the cleaned silt water is discharged to the outside, the filter screen can be cleaned synchronously during water pumping and filtering, and the influence of the blocked filter screen on the water pumping and filtering efficiency is reduced.
本发明公开了一种低影响性的基坑挖掘设备及方法，涉及基坑挖掘技术领域，包括移动车，所述移动车的顶部固定连接有第一泵机，所述第一泵机的一端安装有吸管，该低影响性的基坑挖掘设备及方法，通过设置有喷管、清理槽与开关阀，能够每隔一段时间，第一转辊与第二转辊转动，使得滤网缠绕在第二转辊的外侧，然后第二转辊对应的进管与开关阀打开，第二泵机将清水排入至旋转接头内部，通过软管进入至驱动箱内部，通过打开的进管进入至液腔内部，通过喷管喷在滤网的外侧，水在驱动箱内部向进管内部流动时，水推动扇叶移动，将清洗下来的泥沙水，排出至外界，能够在进行抽水过滤时，同步对滤网进行清理，降低堵塞的滤网对抽水过滤的效率的影响。
