Pore pressure static sounding probe capable of reducing upward pulling force
The invention relates to a pore pressure static sounding probe capable of reducing uplift force, which comprises a detection rod and a conical tip, a cavity is arranged in the detection rod, a pore pressure filter ring is arranged between the detection rod and the conical tip, an air delivery pipe, a waterproof ring, a detection device, a one-way valve and a controller are arranged in the cavity, the waterproof ring is arranged at the upper end of the cavity, and the detection device is arranged in the cavity. The end, penetrating through the waterproof ring, of the air conveying pipe is connected with an air source, the other end of the air conveying pipe is connected with an exhaust pipe and an air hole, and the exhaust pipe is communicated with the air hole which is formed in the ring face of the pore pressure filtering ring. The detection device comprises an electronic vacuum gauge, the electronic vacuum gauge is electrically connected with a controller, the controller is electrically connected with a one-way valve, and the one-way valve is arranged between the exhaust pipe and the gas conveying pipe. The air delivery pipe, the detection device, the one-way valve and the controller are arranged, air is automatically delivered into the hole through the air hole to destroy the negative pressure environment of the hole when the negative pressure condition occurs when the detection rod is pulled out, so that the suction force of the negative pressure to the conical tip is eliminated, and the effect of easily pulling out the detection rod is achieved.
本发明涉及一种可降低上拔力的孔压静力触探探头，包括探测杆和锥尖，探测杆内部开设有空腔，探测杆与锥尖之间设置有孔压过滤环，空腔内设置有输气管、防水圈、检测装置、单向阀门和控制器，防水圈设置于空腔上端，输气管穿过防水圈一端连接有气源，另一端连接有排气管和透气孔，排气管与透气孔连通，透气孔开设于孔压过滤环的环面位置；检测装置包括电子真空计，电子真空计电性连接控制器，控制器电性连接单向阀门，单向阀门设置于排气管与输气管之间。本发明设置输气管、检测装置、单向阀门和控制器在探测杆上拔出现负压情况时通过透气孔向孔洞内自动输气破坏孔洞的负压环境以此消除负压对锥尖的吸力，达到探测杆轻便拔出的效果。
