However, the sensing lines pre-buried in the channel cover plate disclosed by the prior art have low detection sensitivity.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides an it has the channel apron of sensing line to adhere to.

The utility model discloses one of them technical scheme provides a channel apron that has attached to sensing line, the channel apron is including the apron body, the bottom of apron body is attached to the sensing line, the sensing line is connected with the follow the sensing line that stretches out bottom the apron body connects, the sensing line is apart from apron body distance all around and equals.

In a further improved scheme, the sensing wire is tightly combined with the bottom of the cover plate body.

The bottom of injecing sensing line and apron body combines closely and can guarantee that the channel cover board takes place when deformation, and the sensing line can split under the effect of pulling force, and then realizes the detection to the damaged condition of channel cover board.

In a further improved scheme, the cover plate body comprises a cover plate upper part and a cover plate lower part, a reinforcing mesh is preset in the cover plate lower part, and the reinforcing mesh consists of a plurality of reinforcing mesh grids; the lower part of the cover plate is divided into a plurality of hollow grids by the reinforcing mesh, and the sensing wire connectors are positioned in the hollow grids; the sensing line is attached to the bottom of the lower portion of the cover plate.

The reinforcing mesh is arranged in the lower part of the cover plate, so that the anti-damage performance of the channel cover plate can be improved.

In a further improved scheme, the distance between the sensing wire joint and the periphery of the hollow grid is more than 0.5cm, preferably 3-5cm, and the bottom of the sensing wire joint is not higher than the bottom of the lower part of the cover plate.

The distance between the limited sensing line joint and the periphery of the hollow grid is preferably 3-5cm, so that construction is facilitated. And in order to prevent the collision of the sensing wire connector and improve the detection sensitivity, the bottom of the sensing wire connector is not higher than the bottom of the lower part of the cover plate.

In a further improved scheme, the sensing wire and the reinforcing steel bar are not arranged on the same longitudinal section.

The sensing wire should be arranged on the outer ring and cannot be arranged on the same longitudinal section with the reinforcing steel bar. When the channel cover plate is damaged, the breakage of the sensing wire can be ensured.

In a further improved scheme, the sensing line is positioned at 1/2 of the length of the outermost hollow grid around the lower part of the cover plate.

The sensitivity of the sensing line detection at this position is higher.

In a further improved scheme, the ratio of the thickness of the upper part of the cover plate to the thickness of the lower part of the cover plate is 1: 2.

In a further improved scheme, the cross section diameter of the sensing wire is 0.1-2 mm.

In a further improved scheme, the resistance of the sensing line is less than 1 omega.

The sensing wire is ensured to have high detection sensitivity by limiting the resistance value and the cross-sectional diameter of the sensing wire.

The utility model has the advantages as follows: the utility model provides a pair of channel cover plate that has the sensing line adheres to, this channel cover plate bottom adnexed sensing line has high detectivity.
