[0002] With the vigorous development of housing construction and the increasing saturation of urban construction projects, the focus of newly planned domestic projects has gradually shifted to mountainous areas and other outlying areas. In some special areas, housing construction is difficult to construct. For example, the underground foundation in karst areas is unstable, and pile foundations are prone to hit caves during housing construction. In order to ensure the normal progress of housing construction in karst areas, it is necessary to treat the pile foundation caves in karst areas. Before treatment, it is necessary to use a precise positioning device to locate the position of the pile foundation caves.

[0003] However, during the use of the existing pile foundation karst cave positioning detector, the stability of the retracted and deployed suspension cable is insufficient when the detector is retracted and deployed into the pile foundation for karst cave detection, which can easily cause the pile foundation karst cave detector to shake continuously, thereby affecting the normal progress of the detection work. There is a technical problem that the suspension rope cannot be used to limit and guide the retracted and deployed detector to ensure that the device can accurately locate and detect the pile foundation karst cave. Utility Model Content
