The invention discloses a method for detecting, treating and reinforcing the scouring form of a pile foundation. The method comprises the following steps that the form of a scouring pit is detected through scouring pit form detection equipment; the volume of backfilled sandy soil is budgeted; sandy soil is backfilled; pile positions, number and pile length are designed; piling and grouting consumables are calculated; and scheme implementation is reinforced. A scouring form detection and treatment method system effectively applied to actual pile foundation scouring engineering is provided, the problem that the restraining capacity of a soil body on the pile foundation is reduced due to the fact that the soil body around the pile foundation is lost is effectively solved, scouring pit monitoring and scouring pit treatment are closely combined, the volume of sandy soil needing to be backfilled is budgeted and treated, and therefore, the method can be directly applied to actual engineering and solves economic and feasible problems.
Description
technical field [0001] The invention relates to the technical field of pile foundation scour control and reinforcement, in particular to a method for pile foundation scour form detection, control and reinforcement. Background technique [0002] The offshore pile foundation is an important part of offshore wind power. The erosion of waves will damage the subsea soil foundation around the pile foundation, and the soil will form scour pits after being carried away by the water flow. The formation of scour pits will weaken the restraint of the soil on the pile foundation, which will lead to the risk of foundation overturning. Therefore, it is necessary to carry out shape detection and treatment and reinforcement of the scour pits around the pile foundation. [0003] The current protection and treatment methods for scour pits mainly include active protection, passive protection, sand filling treatment, grouting treatment, etc. There are many methods for scour pit shape detection,...
