Abstract

A township road with road edge barrier in mountainous area relates to the field of lane design, especially the design of carriageway in rural lane. As township roads are relatively narrow and mostly built in high mountains and lofty hills, one vehicle is unable to give another the right of way, and is prone to having an accident. In order to reduce the accidents during back off of vehicles on a township road and enhance driving safety, the invention designs the township road with road edge barrier in mountainous area. A technical scheme is as below: two sides of the carriageway are provided with road edge barriers in arc surface with preferable curvature radius R of 30cm; and lay-by positions are arranged at wide spaces at intervals. The edge of the curved surface is preferably provided with a rectangular barrier of 20cm wide and 50cm high; and the rectangular barrier, the arc surface and the carriageway are integrated into a whole. The invention has the following beneficial effects: barriers at road edges can effectively prevent the wheels from slipping off the road, so as to reduce traffic accidents; as the vehicle giving the way performs a slow speed, the arc barriers facilitate guiding the vehicle to keep a right marching direction; and the lay-by positions are helpful to increase the efficiency of the vehicles.

Description

A kind of have a mountain area township road that the limit stops

Technical field

The present invention relates to the design of the runway in lane design field, particularly country lane.

Background technology

Township road, i.e. backroad, general width in the 3M left and right, is the guarantee that the rural area leads to each place, and constructional materials is dark asphalt or cement road, and thickness is approximately 8CM, and township road is the junction that is built in each village mostly.

Township road can't be realized giving another the right of way due to narrower and small, and the township road great majority are based upon between high and steep mountains, and geological stability is relatively poor, and hazards are more; When two cars over against the time, the position that must have a car will move backward and can give another the right of way, the handling and observability during reversing is more very different than moving ahead, and easily meets accident.

Summary of the invention

For reducing the contingency of mountain area township road reversing, strengthen the safety of driving, the present invention designs a kind of mountain area township road that the limit stops that has.

The present invention realizes that the technical scheme that goal of the invention adopts is: a kind of have a mountain area township road that the limit stops, comprise runway, it is characterized in that: have the limit to stop on the both sides of runway, the limit, road stops and is arcwall face, preferred curvature radius R=30cm, material are reinforced concrete; At interval of certain distance, in wrong parking stall, broader position.The rectangle that preferably has wide 20cm, a high 50cm at the edge of arcwall face stops, rectangle stops, arcwall face and runway are integral, and is poured into a mould by reinforced concrete.

The invention has the beneficial effects as follows: stopping of limit, road can effectively stop wheel to skid off runway, reduces traffic accident; The speed of a motor vehicle that gives way due to reversing is slower, and arc stops that being conducive to guided vehicle keeps correct direct of travel; The position of giving another the right of way is conducive to improve the efficient of giving another the right of way.

Description of drawings

Fig. 1 has the mountain area township road schematic diagram that the limit stops.

Fig. 2 is that A-A ' is to the vertical profile schematic diagram.

Wherein, 1, runway, 2, the limit, road stops, 3, the position of giving another the right of way.

The specific embodiment

Having the mountain area township road that the limit stops, is to have the limit to stop 2 on the both sides of runway 1, at interval of certain distance, in broader position wrong parking stall 3.

The limit, road stops 2 for arcwall face, and preferred curvature radius R=30cm, the rectangle that preferably has wide 20cm, a high 50cm at the edge of arcwall face stop (dotted portion in Fig. 2), and rectangle stops, arcwall face and runway are integral, by cement casting.

Claims

1. one kind has the mountain area township road that the limit stops, comprises runway, it is characterized in that: have the limit to stop on the both sides of runway, the limit, road stops and is that arcwall face, material are reinforced concrete; At interval of certain distance, in wrong parking stall, broader position.

2. a kind of mountain area township road that the limit stops that has according to claim 1, is characterized in that: the arcwall face that the limit, road stops, preferred curvature radius R=30cm.

3. a kind of mountain area township road that the limit stops that has according to claim 1 is characterized in that: have the rectangle of wide 20cm, a high 50cm to stop at the edge of arcwall face, rectangle stops, arcwall face and runway are integral, and is poured into a mould by reinforced concrete.
