Construction method for removing mud in jacket steel pipe pile

A construction method for removing a mud in a jacket steel pipe pile, comprising:

• erecting a piling auxiliary platform, and performing underwater steel pipe pile sinking;
• measuring an elevation of a mud surface in an underwater steel pipe pile, and calculating a height from the mud surface in the underwater steel pipe pile to a pile top and a needed mud removing depth according to a measurement result;
• wherein the needed mud removing depth H=an elevation H1 of the mud surface in the underwater steel pipe pile—an elevation H2 of a designed mud surface in the underwater steel pipe pile;
• installing a mud removing equipment on the underwater steel pipe pile;
• and
• starting the mud removing equipment to carry out a mud removing operation, and when the needed mud removing depth is reached, pausing the mud removing equipment, and cleaning an inner wall of the underwater steel pipe pile;
• and when the mud removing operation does not reach a related elevation, repeating the mud removing operation till the mud removing operation reaches a standard;
• wherein the mud removing equipment comprises a transmission main shaft, a mud suction mechanism, a pile head support, a driving assembly, and a drill bit assembly;
• the transmission main shaft is arranged inside the underwater steel pipe pile, and the transmission main shaft is of a hollow structure;
• the mud suction mechanism is installed at a top portion of the transmission main shaft;
• a center of the pile head support is rotationally connected with the transmission main shaft, and an outer side of the pile head support is installed at an end portion of the underwater steel pipe pile;
• the drill bit assembly is installed at a bottom portion of the transmission main shaft, and the drill bit assembly comprises a mud barrel, an inner mud cutting turbine, and an outer mud cutting turbine;
• the inner mud cutting turbine is detachably connected with the transmission main shaft, the outer mud cutting turbine is arranged on an outer side of the inner mud cutting turbine, and the mud barrel is arranged between the inner mud cutting turbine and the outer mud cutting turbine;
• the driving assembly is further provided with a torque sensor, and a completed mud removing depth is obtained based on a numerical value of the torque sensor and in combination with a mud removing depth measured by a construction;
• and
• the underwater steel pipe pile is further provided a climbing device, wherein the climbing device comprises a climbing rack, a climbing gear, a climbing transmission motor, and a climbing support;
• the climbing gear is installed on the transmission main shaft through the climbing support, the climbing gear is further engaged with the climbing rack, and the climbing gear is further installed at a driving end of the climbing transmission motor;
• and the climbing rack is longitudinally installed on the underwater steel pipe pile.
