Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like figure 1 As shown, an automatic post-construction settlement monitoring system for expressways includes a reference column 1, a settlement column, and a scale line is marked on the settlement column; the settlement column includes a subgrade toe settlement column 2, a shoulder settlement column 3, and a subgrade centerline settling column 4;

[0028] The reference column 1 is set at point A on one side of the subgrade, and the side of the reference column 1 facing the settlement column 2 at the foot of the subgrade is provided with a groove I5 with a horizontal opening, and a measuring box is installed in the groove I5; point A The position is the datum point, which is the point that does not settle or settles slowly.

[0029] The subgrade slope toe settlement column 2 is arranged at point B of the subgrade slope toe, and the side of the subgrade slope to...

Abstract

The invention discloses an automatic monitoring system and method for expressway post-construction settlement. The system comprises a datum column arranged on a datum point, and settlement columns arranged on a roadbed slope foot, a road shoulder and a roadbed center line correspondingly, wherein scale lines are marked on the settlement columns. Measurement boxes are arranged in the datum column and the settlement columns arranged on the roadbed slope foot and the road shoulder. Each measurement box comprises a high-precision laser locating lamp, a wireless transmission camera, a power sourcetimer and a high-energy storage battery. The laser locating lamps in the measurement boxes shine on the corresponding settlement columns marked with the scales, and meanwhile photograph the light spotcorresponding scales to be transmitted to a could server, the server calculates relative settlement of all measurement points and accumulates the settlement to obtain the settlement amount of the road surface relative to the set base point. The automatic monitoring system for post-construction settlement is easy to install and operate, the cost needed by the equipment is low, maintaining is convenient, batteries in the measurement boxes only need to be replaced regularly, the number of externally-connected circuits is reduced, the service life is prolonged, the stability is high, and real-time monitoring can be carried out for a long term conveniently.

Description

technical field [0001] The invention relates to an automatic monitoring system and method for expressway post-construction settlement, belonging to the technical field of highway settlement monitoring. Background technique [0002] With the development of modern society and economy, the construction of highways is increasing, and highways have very high requirements for foundations. At present, the foundation soil in my country's coastal areas has the characteristics of high water content, high compressibility and low strength. Therefore, the construction of highways in my country's coastal areas Subsidence and differential settlement diseases of roadbed are common in expressways. Post-construction settlement, especially uneven settlement, will inevitably cause unevenness of the road surface, resulting in many diseases on the road surface, mainly manifested as road arch deformation, structural layer cracking, floor voiding, pavement dislocation, muddying, potholes, cracks, an...
