The invention provides a lossless sonar detection system and method for pile bottom karst of a cast-in-place pile. The lossless sonar detection system comprises a motion module, an inertia measurement module, a sonar detection module, a driving module and a control module, wherein the sonar detection module collects sonar data by using mud in a pile hole as a sound wave propagation and coupling medium and feeds back the sonar data to the control module; the control module is used for acquiring and processing data of the sonar detection module and then outputting a control instruction to the driving module; and the driving module is used for driving the motion module to move according to the control instruction. According to the lossless sonar detection system and method, the sonar technology is applied to pile bottom karst cave detection, slurry in the pile hole serves as the sound wave propagation and coupling medium to detect the karst cave development condition of the pile bottom, and the technical problem of how to effectively and rapidly detect the pile bottom karst cave of the cast-in-place pile is solved, so as to ensure that no karst cave exists within a range that the three-time pile diameter of the pile bottom of each pile is not smaller than 5 m.
