[0024] In the prior art, in order to prevent rainwater and other road surface drainage from entering the tunnel and affecting driving safety and comfort, the following two water interception measures are usually adopted: a transverse road surface interception ditch with a water grate at the tunnel entrance or a transverse interception ditch with an opening. The former is to add a water-flowing cast iron grate cover plate on the basis of the transverse rectangular road surface interception ditch, which is easy to cause the vehicle to jump at the tunnel entrance, and there are problems such as high construction difficulty, poor surrounding compaction and easy settlement; the latter also has the problem of easy vehicle jumping.

[0025] The embodiment of the utility model realizes the combination of open ditch and hidden ditch by arranging water interception port, water interception ditch and drainage ditch. The water interception port and water interception ditch are open ditch and the drainage ditch is hidden ditch, thereby effectively intercepting water flowing on the road surface, overcoming the problem that vehicles are prone to jumping out of the existing water interception ditch, improving driving safety and comfort, and solving the problems of vehicles being prone to jumping out, difficult construction, loose surrounding pressure and easy settlement in related technologies.

[0026] The utility model fully combines the characteristics of the longitudinal and transverse combined slopes of the road surface, intercepts the road surface water on the combined slope, and the road surface interception ditch is set to be open, arranged obliquely, and obliquely intersects with the driving wheels, thereby avoiding the vehicle jumping phenomenon. The cutting of the road surface by a single oblique ditch affects the driving psychology of the driver, so multiple oblique interception ditches are used. Then the transverse ditch is used to collect and centrally drain to the roadside ditch, and the transverse ditch is set as a dark ditch.

[0027] According to an embodiment of the utility model, the inclination direction of the water cutoff is perpendicular to the combined slope formed by the transverse slope and the longitudinal slope along the road direction, and is used to intercept the water flow of the combined slope. The inclination angle α of the water cutoff relative to the transverse slope direction is 30°-60°. Figure 2 As shown; if the transverse slope is 1.5%, when the longitudinal slope is greater than 2.6%, the inclination angle is equal to 30°; when the longitudinal slope is less than 0.9%, the inclination angle is equal to 60°.

[0028] According to an embodiment of the utility model, the relationship between the number N of the cut-off openings and the slope β of the combined slope is: Where W is the road width, L is the length of the road slope, R is the rainfall, and k is the adjustment parameter. k is used to balance the effects of road width, slope length, rainfall, diagonal length of the cutoff, and road slope on the number of cutoffs.

[0029] According to an embodiment of the utility model, the plane line shape of the oblique opening of the water cutoff is a straight line, and the shape of the water cutoff is a rectangle, a trapezoid or a V-shaped groove. According to an embodiment of the utility model, the plane line shape of the oblique opening of the water cutoff is a curve, and the water cutoff is in an arc shape.

[0030] According to an embodiment of the utility model, the cross-sectional shape of the intercepting ditch is rectangular, circular or polygonal.

[0031] According to an embodiment of the utility model, the cross-sectional shape of the drainage ditch is rectangular, circular or polygonal.

[0032] According to an embodiment of the utility model, the surface of the water cutoff is designed to be smooth.

[0033] According to an embodiment of the utility model, the surface of the water cutoff is coated with an anti-adhesion coating to reduce the adhesion of dirt.

[0034] In the prior art, dirt is easily accumulated in the intercepting drainage ditch at the intercepting outlet. The embodiments of the utility model provide intercepting outlets and intercepting drainage ditch with specific shapes, design the surface of the intercepting outlet to be smooth, and apply an anti-adhesion coating on the surface of the intercepting outlet, which is beneficial to the smoothness and uniform distribution of water flow, reduces the friction resistance in the water flow, reduces the accumulation of dirt at the intercepting outlet, and solves the technical problem that dirt is easily accumulated in the intercepting drainage ditch at the intercepting outlet.

[0035] The beneficial effects of the utility model are as follows: the open intercepting ditch is combined with the concealed ditch, the open intercepting ditch is obliquely arranged by utilizing the characteristics of the road combined slope, and obliquely intersects with the driving wheels to overcome the vehicle jumping phenomenon, thereby improving driving safety and comfort.

[0036] The above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other changes or modifications in different forms may be made based on the following description, and these changes, modifications, substitutions and deformations derived from the principles and spirit of the present invention still fall within the scope of protection of the present invention.
