Abstract

The invention discloses a device and a method for monitoring the height of a soil core in a tubular pile. The device comprises a first pulley, a second pulley, a winding drum assembly, a concentric cable, a resistance tester, a winding drum control all-in-one machine, a computer and a heavy ball, wherein the heights of the first pulley and the second pulley are set to be the same ; the winding drum assembly comprises a winding drum, a torque sensor and a driving device; the winding drum control all-in-one machine is electrically connected with the torque sensor and the driving device; the heavy ball is connected with the concentric cable; the concentric cable sequentially bypasses the first pulley and the second pulley and then is connected with the winding drum; the concentric cable comprises a third cable and a metal hose; the metal hose is insulated from the first pulley and is electrically connected with the second pulley; the second pulley is electrically connected with the resistance tester through a first cable; the other end of the third cable is electrically connected with the resistance tester through the second cable; and the computer is connected with the winding drum control all-in-one machine and the resistance tester. The device and the method solve the problems that an existing soil core height measuring device and method are difficult to collect the soil core height and the safety risk is high.

Description

technical field [0001] The invention belongs to the technical field of marine geotechnical engineering and pile foundation engineering, and in particular relates to a monitoring device and a monitoring method for the height of the inner soil core of a pipe pile. Background technique [0002] Prefabricated pipe piles such as steel pipe piles and prestressed concrete pipe piles are common pile foundation types for buildings, bridges, port terminals, and offshore wind power projects. Prefabricated pipe piles are usually sunk into the foundation soil by means of impact, vibration and static pressure. The tip of the prefabricated pipe pile is generally open or semi-closed. During the process of penetrating into the soil layer, the interior of the pipe pile will be filled with the soil core. Due to the frictional resistance between the soil core and the inner wall of the pipe pile and the influence of the soil arch effect, the pipe pile may be blocked during the pile sinking proc...
