Embodiment 1

[0104] According to the construction drawing of the concrete road (road) surface slab, mark the position corresponding to the slit of the surface slab and the center of the slab on the base. The layout points A and B are respectively marked on the outer side of the road between the cuts of the near road surface and the middle of the two adjacent road surface cuts. The distance between B and the cuts is 5cm. Mark A1, A2, A3, B1, B2, and B3 at 15cm respectively as the preset hole positions of the steel column for the installation position of the three-axis deformation monitoring device.

[0105] Inorganic binder stabilized materials are used as the material of the concrete road (road) surface base, and the construction thickness is 20cm. After the construction and maintenance of the concrete road (road) surface base is completed, according to the pre-set installation position of the triaxial deformation monitoring device, the reinforcement column For the layout of the holes, use...

Abstract

The invention relates to the field of road engineering, in particular to a cement concrete pavement early deformation monitoring structure and method. The early deformation monitoring structure for the cement concrete pavement comprises a pavement body. The pavement body comprises a surface layer, a base layer and a pavement kerf positioned on the surface layer; and the plurality of three-axis displacement monitoring devices are uniformly arranged at intervals. The XY surface of the three-axis displacement monitoring device is arranged on the plane where the junction of the surface layer and the base layer is located, and the three-axis displacement monitoring device is at least partially arranged on the outer side of the pavement main body. According to the early deformation monitoring structure and method for the cement concrete pavement, the deformation condition of the cement concrete pavement in the initial operation stage can be monitored in real time. Therefore, pavement structural damage and potential safety hazards possibly caused by excessive deformation at the initial stage of pavement operation are monitored in time, and the effect of precaution is achieved.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a monitoring structure and method for early deformation of cement concrete pavement. Background technique [0002] With the development of highway and airport construction in our country, the construction scale is constantly expanding, and the requirements for highways (runways) are also increasing. The early deformation of the road (road) surface can often reflect the damage trend of the road (road) surface in the long-term operation state, which is extremely important for the normal operation of the runway. If the early deformation of the road (road) surface is large, it may mean that with the increase of running time, the degree of deformation of the road (road) surface will increase seriously, which may cause bumps in the driving process and affect driving stability. It poses a serious threat to the operational safety of the road (road). [0003] At present, the commonly use...
