Abstract

A shell is provided with a containing cavity and a receding hole communicating with the containing cavity, a transducer is located in the containing cavity, the excitation face of the transducer faces the receding hole, and a first connecting part and a second connecting part are connected with the shell. And two adjacent transducer units can be connected through the first connecting part of one transducer unit and the second connecting part of the other transducer unit. The invention further discloses a karst cave detector, a plurality of transducer units are connected with one another to form a transducer assembly, and the collector is provided with a plurality of cable sockets so as to transmit signals collected by the transducer units to the host. Due to the fact that every two adjacent transducer units can be connected through the corresponding first connecting part and the corresponding second connecting part, the adjacent transducer units can be expanded, the use requirements of pile foundations with different diameters are met, the amount of data collected by a karst cave detector formed after the transducer units are expanded meets the requirements, and the accuracy of karst cave detection is improved.

Description

technical field [0001] The present application relates to the technical field of geological exploration, in particular to a transducer unit and a cave detector. Background technique [0002] The geological stability of the karst cave area has seriously affected the safe construction of roads and bridges in the lava area. Usually, it is necessary to detect the internal structure of the cave to determine the three-dimensional shape and size of the cave, and then construct the pile foundation. Due to the huge difference in the size of the caves, the ever-changing shapes, and the extremely irregular cross-section shapes, it has brought great difficulties to the design and construction of pile foundations in the cave area. It is difficult to accurately design the bearing capacity of the pile foundation when the development of karst caves is not proven. At the same time, when constructing cast-in-situ piles in the stratum with developed karst caves, there is a high possibility of...
