Surveying and mapping device provided with multi-point measuring structure and used for detecting foundation pit subsidence

Abstract

The invention belongs to the technical field of engineering surveying and mapping devices and relates to a surveying and mapping device provided with a multi-point measuring structure and used for detecting foundation pit subsidence. The surveying and mapping device comprises a transmission assembly, a subsidence instrument assembly and an inductance sensor; a lifting assembly is fixedly connectedat the upper portion of the transmission assembly and comprises a shell; a damping support is fixedly connected to the interior of the shell; a motor is fixedly connected to the upper portion of thedamping support; a driving shaft is fixedly connected to the right side of the motor; the subsidence instrument assembly is fixedly connected to the lower portion of the lifting assembly; and a protection assembly is arranged outside the subsidence instrument assembly. According to the surveying and mapping device, the surveying and mapping device is arranged to be a multi-connector connecting device; the device can perform subsidence degree detection on different positions in the using process, achieves multi-line detection, compares and analyzes detected numerical values, and measures the overall subsidence degree of a foundation pit; and the detection precision and the detection efficiency of the surveying and mapping device can be improved through multi-point comparison.

Description

technical field [0001] The invention relates to the technical field of engineering surveying and mapping devices, in particular to a surveying and mapping device for foundation pit subsidence detection with a multi-point measuring structure. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. If the excavation is not deep, you can use the method of setting the side slope to stabilize the soil slope. The slope size is determined according to the relevant construction regulations. If the excavation is deep and there are buildings nearby, you can use the method of foundation pit wall support, shotcrete retaining method, and large-scale excavation. The foundation pit even adopts methods such as underground diaphragm wall and column-type bored pile interlocking to protect the outer soil layer from collapsing. There is no influence on nearby buildings. The well point...
