Construction device suitable for silty-fine sand stratum foundation pit dewatering
The invention relates to a construction device suitable for silty-fine sand stratum foundation pit dewatering, and belongs to the technical field of civil engineering. The construction device suitable for silty-fine sand stratum foundation pit dewatering is located on a foundation and comprises a supporting table and a water tank; the supporting table is located at the edge close to the foundation pit, a jet pump and a driving motor are arranged on the supporting table, a barometer is arranged on the jet pump, a water suction pipeline is fixedly connected with one end of the jet pump, and the other end of the jet pump communicates with a water collecting tank through a water outlet pipeline; a main water pumping pipe is horizontally arranged in the foundation pit, the water suction pipeline communicates with the main water pumping pipe, and the main water pumping pipe communicates with a plurality of vertically arranged water pumping pipes; water inlet holes are formed in the wall of the water pumping pipe; the water pumping pipe needs to extend below the bottom surface of the foundation pit; a grouting pipe is located on the pit wall of the foundation pit and controls the grouting flow through the driving motor; and a pore pressure meter is arranged on the water pumping pipe. The construction device suitable for silty-fine sand stratum foundation pit dewatering is reasonable in arrangement, drainage is carried out through the jet pump, and the effect is stable; and multi-directional drainage requirements can be effectively and flexibly met.
本发明涉及一种适用于粉细砂地层基坑降水的施工装置，属于土木工程技术领域。适用于粉细砂地层基坑降水的施工装置，其位于地基上布置支撑台、水箱；支撑台位于靠近基坑的基坑边缘，支撑台上设有射流泵及驱动电机，射流泵上设有气压表，射流泵的一端固接有吸水管道，射流泵的另一端通过出水管道与集水箱相连通；基坑内水平布设总抽水管，吸水管道与总抽水管相互连通，总抽水管与若干个竖向布设抽水管相互连通；抽水管管壁上设有进水孔；抽水管需深入基坑底面以下；注浆管位于基坑坑壁处，注浆管通过驱动电机控制注浆流量；所述的孔压计布置在抽水管上。本发明提供设置合理，利用射流泵进行排水，效果稳定。可以有效灵活地适应多方向的排水需求。
