Description
Technical Field
The utility model relates to an reinforcing abrupt slope top field of vision device belongs to town road facilities technical field.
Background
The access & exit and the great highway section of mountain area road fluctuation of underground parking garage, the ubiquitous abrupt slope, navigating mate when the abrupt slope from top to bottom, the blind area in vehicle the place ahead is more showing at gentle highway section and is increasing, on the road surface on a large scale in vehicle the place ahead, navigating mate can't see, not only has great traffic safety hidden danger, also causes very big psychological pressure for the navigating mate in addition. Traffic accidents caused by steep slopes up and down sometimes occur, and personal injury and property loss are caused. For how to improve the traffic safety of the steep slopes up and down, the prior art mainly adopts measures of limiting the speed of a vehicle, reminding a driver of driving cautiously and the like, but cannot fundamentally solve the traffic safety hidden trouble. The above disadvantages are urgently needed to be improved.
Disclosure of Invention
An object of the utility model is to overcome the not enough of existence among the prior art, provide a reinforcing abrupt slope top field of vision device, come the supplementary navigating mate and observe the place ahead road surface, can in time know the road surface condition of vehicle the place ahead blind area scope through the sight glass, reduce because of the traffic accident that vehicle the place ahead blind area caused, also slowed down navigating mate's psychological pressure.
According to the utility model provides a technical scheme: the utility model provides an strengthen abrupt slope top field of vision device, includes basis, support, denoter and sight glass, the basis is installed underground, sets up the support on the basis, install denoter and sight glass on the support.
Further, the support is L-shaped, and comprises an upright rod fixedly connected with the foundation and a cross rod horizontally arranged on the upright rod, and the sign board and the observation mirror are arranged on the cross rod.
Furthermore, the observation mirror is a convex spherical mirror, and the mirror body is made of plastic materials or glass materials.
Further, the material of the bracket is a metal material or a composite material.
Compared with the prior art, the utility model, have following advantage:
through setting up the sight glass in abrupt slope top, navigating mate can in time know the road surface condition of vehicle the place ahead blind area scope through the sight glass when the abrupt slope from top to bottom, reduces the traffic accident because of vehicle the place ahead blind area causes, has also slowed down navigating mate's psychological pressure.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the device for enhancing the top view of the steep slope comprises a foundation 1, a support 2, a sign board 3 and an observation mirror 4, wherein the foundation 1 is installed underground, the support 2 is arranged on the foundation 1, and the sign board 3 and the observation mirror 4 are installed on the support 2. The foundation 1 is a buried part of a facility and is used for fixing the support 2, and the foundation 1 can be cast in place or prefabricated for concrete; the bracket 2 can be made of metal materials or composite materials;
the support 2 is L-shaped, and comprises a vertical rod fixedly connected with the foundation 1 and a cross rod horizontally arranged on the vertical rod, and the signboard 3 and the observation mirror 4 are arranged on the cross rod.
The observation mirror 4 is a convex spherical mirror, and the mirror body is made of plastic materials or glass materials.
The utility model discloses an installation method of position, including following step:
(1) surveying the terrain near a steep slope, including vertical curves of a longitudinal slope and a variable slope of a road; referring to fig. 2 and 3, in the present embodiment, the width of the garage exit road is 4m, the longitudinal slope of the exit road is 20%, the slope of the ground road is 0%, and the vertical curve of the slope changing point is 0.
(2) Surveying vehicles passing through roads, and determining the size and the passing clearance of the vehicles according to the selected vehicle type; in this embodiment, the underground garage is special for the use of resident private car, and the vehicle is passenger train. According to the relevant specifications, the external porch dimensions of a passenger car: the total length is not more than 6m, the total height is not more than 2m, and the total width is not more than 1.8 m; the minimum clear height of the ramp is 2.2 m.
(3) Simulating the conditions of the vehicle when the vehicle passes through a flat slope and a steep slope, and determining a blind area in front of the vehicle and the visual field of a driver in the vertical direction; in the present embodiment, referring to fig. 4 and 5, the flat slope is about 2.5m, and the steep slope is about 8 m; the driver's field of view is in the vertical direction, which is about 25 to 35 degrees.
(4) Determining the proper position of the observation mirror 4 and the installation angle of the observation mirror 4 according to the simulation result;
(5) calculating the position of the bracket 2 according to the position of the observation mirror 4, and further determining the position of the foundation 1;
(6) and installing facilities on site and debugging the angle of the observation mirror 4 so as to meet the use requirement of a driver and meet the requirement of road passing clearance. After comparison and selection, see fig. 6 and 7, it can be determined that the observation mirror is in the air 3m in front of the slope change point and 3m away from the ground. The height H =3m of the horizontal support, the height H of the lower edges of the observation mirror 4 and the signboard 3 should meet the requirement of road clear height, and the distance D between the outer edge of the support 2 and the roadside should meet the requirement of road clear width.
The way of simulating the situation of the vehicle when passing through a flat slope and a steep slope can be manual drawing on a drawing or computer-assisted drawing or field test.
It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
