Fixed catheter traction sensor and method of use

Abstract

The invention provides a fixed conduit traction sensor and a use method thereof, including a wind power pipe pile, a ship, a solidified soil conveying device, a ship traction device, and a sounding sensor; The conveying device transports the solidified soil in the ship to the scour pit of the pile foundation of the wind power pipe pile. The depth-sounding sensor is installed on the ship's traction device, and the depth-sounding sensor is used to measure the depth of the scour pit. Therefore, taking advantage of the characteristics of high fluidity of the solidified soil, the solidified soil can be pumped to the designated position by using the on-board deployment and direct pumping process, covering the whole area, and can be operated on a large scale, which greatly shortens the working time at sea. The ship traction device does not need to be close to the pile foundation during construction, which can greatly reduce the accidental damage caused by the collision of pile foundation and submarine cable during construction. The safety protection is reliable and guaranteed, and the normal operation of the wind farm will not be affected during construction.

Description

technical field [0001] The invention relates to the field of wind power pile foundation scour pit treatment, in particular to a fixed conduit traction sensor and a use method. Background technique [0002] Wind power pipe piles or piers of cross-sea and river-crossing bridges will be deeply buried in the seabed, and sea water will wash away wind power pile foundations or bridge pier pile foundations, which will form scour pits around the pile foundations, which will lead to unstable pile foundations and potential safety hazards , so it is necessary to control the scour pit. [0003] Existing treatment methods for scour pits include dumping and filling (including sandbags, riprap, prefabricated concrete components, etc.), geotextile compaction, bionic aquatic weed treatment, reserved scour length and solidified soil dredging and filling. When the solidified soil is blown and filled, due to the waves, the position of the ship is difficult to stabilize, which is likely to caus...
