Underwater drilling and coring detection method and underwater drilling and coring device
The invention relates to an underwater drilling and coring detection method and an underwater drilling and coring device, and belongs to the technical field of underwater drilling and coring. The underwater drilling coring detection method comprises the steps of protecting pipe mounting, drilling machine positioning, casing pipe sinking, hole cleaning, pile top standard penetration test, coring, pile bottom supporting layer standard penetration test and core sample strength and deformation modulus detection. According to the underwater drilling coring detection method, a standard penetration test is carried out in the coring process, the standard penetration test and drilling coring can share one drilling hole, meanwhile, a drilling core sample is used for carrying out strength and deformation modulus tests, three tasks are completed through one-time drilling, the workload can be reduced, the construction period can be shortened, the detection efficiency can be improved, and the overall cost can be reduced; moreover, according to the method, through a pile top standard penetration test, a pile bottom bearing layer standard penetration test and detection of strength data and deformation modulus data of a core sample, comprehensive quality detection can be conducted on the pile to be detected, and the method is suitable for drilling and coring detection work of the underwater DCM pile.
