Abstract

The invention relates to a ground subsidence measuring device, which relates to the technical field of road measurement, and comprises a hollow sleeve placed at a subsidence part, and is characterizedin that the hollow sleeve is rotatably connected with a plurality of support arm structures for supporting the hollow sleeve on the ground around the subsidence part; supporting structures for fixingthe corner of the supporting arm structure are arranged between the supporting arm structures of the hollow sleeve, and the top end of the hollow sleeve is provided with a depth measuring structure for measuring the depth of the sinking position and a diameter measuring structure for measuring the inner diameter of the sinking position. A driving mechanism for driving the depth measuring structure and the diameter measuring structure to move in the vertical direction is arranged at the top end of the hollow sleeve, and transmission structures for transmitting power of the driving mechanism are fixedly connected to the depth measuring structure and the diameter measuring structure. The volume of the subsidence position is calculated by measuring the depth and the width of the subsidence position, and the device has the effect of calculating the material required by the subsidence position.

Description

technical field [0001] The present application relates to the technical field of road measurement, in particular to a ground subsidence measurement device. Background technique [0002] The impact of road drop subsidence on the safety of vehicles running at high speed has gradually been paid attention to. At present, the measurement of road subsidence in the industry is usually carried out by professional surveyors operating civil engineering measuring instruments such as theodolite and level. Measure in a working way to obtain the drop subsidence situation and drop subsidence value of each road section. [0003] With the development of science and technology, the road measurement equipment is also constantly developing and improving. Among them, the road subsidence measurement device is also widely used, but the road subsidence measurement device on the market is still complicated in structure, and it is very troublesome to measure and carry. The measurement cannot be comp...
