Intelligent monitoring system for tunnel power supply

Abstract

The invention discloses an intelligent monitoring system for tunnel power supply. The intelligent monitoring system comprises a cavity detection unit used for collecting length information of a cavity; a first judgment unit used for screening and marking the cavity detection units located in the cavities influencing the concrete structure according to a first preset condition; a second judgment unit used for screening and marking the cavity detection units located in the cavities influencing the concrete structure according to a second preset condition; and a concrete supplement amount calculation unit used for acquiring the position information of the cavity detection units in the marked cavity detection unit set on the tunnel lining template and calculating the concrete supplement amount. The cavity detection unit is supplied with power to detect whether a cavity exists in concrete and whether the cavity affects the structural strength of the lining concrete layer, the position of the cavity is positioned, the concrete is supplemented and filled in time to make up defects, and the cavity affecting the structural strength of the lining concrete layer is avoided.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, more specifically, it relates to an intelligent monitoring system for tunnel power supply. Background technique [0002] After the excavation of the tunnel, the original balance of the strata around the tunnel is destroyed, causing the tunnel to deform or collapse. In order to protect the stability of the surrounding rock and ensure the safety of driving, the tunnel must have a supporting structure with sufficient strength, that is, the tunnel lining. Tunnel lining is a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body in order to prevent the deformation or collapse of the surrounding rock. [0003] Such as figure 1 Shown is a construction schematic diagram of tunnel lining concrete pouring in the prior art. A plurality of tunnel lining formworks 102 are supported by formwork brackets 101 to form an arched structure...

Problems solved by technology

[0003] like figure 1 Shown is a construction schematic diagram of tunnel lining concrete pouring in the prior art. A plurality of tunnel lining formworks 102 are supported by formwork brackets 101 to form an arched structure, and a gap is formed between the tunnel lining formwork 102 and the inner wall of the tunnel. Several work windows 103 are arranged on the top, and concrete is poured into by the work windows 103; figure 2 As shown, the thickness of the tunnel lining concrete pouring is relatively large, and it is easy to produce cavities in the poured concrete, and the large cavities will affect the structural strength of the lining concrete layer
