Layered detection device for road subsidence

Abstract

The invention discloses a layered detection device for road subsidence. The detection device includes a pair of support bodies, each supporting main body is provided with an extending part I used forfixing, the outer wall of each supporting main body is provided with a fixing ring, a detection main body used for subsidence detection is clamped in each fixing ring in a lifting mode, and each detection main body comprises a supporting arm I, a supporting arm II clamped on the inner side of the supporting arm I in a lifting mode and a supporting arm III clamped on the inner side of the supporting arm II in a lifting mode. The roadbed subsidence detection device has the following beneficial effects: real-time subsidence detection is carried out on roadbed supporting soil layers with differentdepths through the detection device, so that a road detection worker can discover a soil layer with a subsidence condition in time, the detection efficiency of road subsidence is improved, and the subsidence soil layer is convenient to fill and repair in time.

Description

technical field [0001] The invention relates to the technical field of road detection, in particular to a road subsidence layered detection device. Background technique [0002] The subgrade soil layer of the road is the basis for the stable support of the road. After the road is laid, the stability test of the subgrade support soil layer is the basis for judging whether the road will subside. In areas where precipitation is concentrated and near irrigation channels, due to Due to water erosion and long-term immersion, potholes will appear in the supporting soil layer of the subgrade and gradually form subsidence, which will reduce the supporting force of the subgrade supporting soil layer on the road, reduce the bearing capacity of the road, and at the same time there is a risk of road fracture. The method of on-site drilling and coring of the road soil layer is less flexible in the process of use, and because it cannot perform real-time detection, in order to understand th...

[0002] The subgrade soil layer of the road is the basis for the stable support of the road. After the road is laid, the stability test of the subgrade support soil layer is the basis for judging whether the road will subside. In areas where precipitation is concentrated and near irrigation channels, due to Due to water erosion and long-term immersion, potholes will appear in the supporting soil layer of the subgrade and gradually form subsidence, which will reduce the supporting force of the subgrade supporting soil layer on the road, reduce the bearing capacity of the road, and at the same time there is a risk of road fracture. The method of on-site drilling and coring of the road soil layer is less flexible in the process of use, and because it cannot perform real-time detection, in order to understand the subsidence of the road subgrade support soil layer, high-frequency drilling and coring is required , resulting in an increase in work intensity
