Truck escape ramp

Abstract

The invention discloses a truck escape ramp, and aims to provide the truck escape ramp which can be constructed in a complex terrain to improve the traffic safety. The truck escape ramp includes a tunnel type brake lane penetrating a mountain body, wherein the entrance of the brake lane is connected with a traffic lane through an approach road, the exit of the brake lane extends out of the mountain body and is then connected to a service lane on the outer surface of the mountain body, and the service lane extends along the surface of the mountain body and is then connected onto the approach road. Through a reasonable structural design, the tunnel type truck escape ramp can be arranged at a location of the complex terrain in a mountainous area where common truck escape ramps cannot be arranged, so as to greatly improve the traffic safety of the complex terrain in the mountainous area, reduce as many traffic accidents as possible, effectively protect the personal safety of a driver and passengers, and lessen the financial losses caused by driving faults.

Description

technical field [0001] The invention relates to the technical field of highway construction, in particular to an escape lane. Background technique [0002] China's mountains and hills account for about 43% of the country's land area, and mountain roads overcome the height difference and inevitably have continuous downhill. Accident statistical analysis shows that no matter it is a general road or an expressway, the continuous downhill road section has a high incidence of accidents, and serious and extremely serious accidents account for a relatively high proportion. Although the traffic accidents on mountainous roads account for a small proportion of national traffic accidents, there are many serious traffic accidents involving mass casualties and mass injuries. [0003] In particular, the terrain and geological conditions in the plateau mountainous area are complex, and the ecological environment is greatly restricted. The long and downward slope is a relatively common lin...

Problems solved by technology

In the current design, the safe-haven lanes at home and abroad are all set on the subgrade section, avoiding bridges and tunnels and other structures, and at the same time need to be set on the side of the mountain, but the complex terrain of mountainous areas often leads to no place for setting where it needs to be set and conditions, resulting in the failure of construction in some areas that need to set up escape lanes, and there are potential safety hazards
