Abstract

A construction method for removing mud in a jacket steel pipe pile includes: erecting a piling auxiliary platform, and performing underwater steel pipe pile sinking; measuring an elevation of a mud surface in the underwater steel pipe pile, and calculating a height from the mud surface in the pile to a pile top and a needed mud removing depth according to the measurement result; installing mud removing equipment on the steel pipe pile; starting the mud removing equipment to carry out mud removing operation, and in a case that the mud removing depth is reached, pausing the mud removing equipment, and cleaning an inner wall of the steel pipe pile; and in a case that the mud removing operation is not reach the related elevation, repeating the mud removing operation till the mud removing operation reaches a standard.

Abstract

The present application discloses a construction device implementing ex-situ solidification and anti-scouring of fluidized solidified soil in offshore wind power, comprising: a first stirring module, a feeding module, a second stirring module, an auxiliary material feeding module, and a transportation module. The feeding module is connected to the first stirring module and the second stirring module, the auxiliary material feeding module is connected to the second stirring module, and the transportation module is connected to the second stirring module. The present application can make the construction method continuous, standardized, efficient, etc., and effectively solves the problem that existing construction is rough; and by means of continuous stirring and continuous transportation, the field construction window period is shortened.

Abstract

A construction method for cleaning mud in a jacket steel pipe pile, comprising: setting up a pile driving auxiliary platform (M1), and performing pile sinking of an underwater steel pipe pile (5); measuring the elevation of a mud surface in the underwater steel pipe pile (5), and calculating the height from the mud surface in the pile to the pile top and the depth required for mud cleaning according to the measurement result; mounting a mud cleaning device (M7) on the steel pipe pile (5); starting the mud cleaning device (M7) to perform a mud cleaning operation, and if the mud cleaning depth is reached, pausing the mud cleaning device (M7) and cleaning the inner wall of the steel pipe pile (5); and if the mud cleaning operation does not reach the designed elevation, repeating the mud cleaning operation until the mud cleaning operation reaches the elevation.
