Description
Technical field
The utility model relates to highway emergency lane technical field more particularly to a kind of novel buffer type hedging vehicles
Road.
Background technique
Emergency lane refers to that adds on the outside of the runway of long sharp decline section sails for speed runaway (brake failure) vehicle
From the dedicated Lanes that main track slows down safely, emergency lane should have there are two effect: first is that shunting errant vehicle from main line, keep away
Exempt to interfere main line vehicle；Second is that errant vehicle is made steadily to stop, should not occur casualties, vehicle it is badly damaged and dress
The phenomenon that loading object is seriously scattered.
Road Design specification regulation: emergency lane should be arranged on straight line, drive into enable the vehicle to high-speed secure, before entrance
It should ensure that enough sighting distances.Emergency lane (braking slope bed) starting point is thick using 0.1m, with 30m length gradual change to slope aggregate total thickness
Degree.The discrete materials such as crushed-gravel, gravel, sand, beans gravel can be used in slope aggregate, with a thickness of 0.3~0.9m, brake slope bedside degree
Not less than 4.5m, service road width is not less than 3.5m, and anchor bolt of recovering interval is not preferably greater than 90m, and compulsive slowdown device can be used
Sand pocket or damaged tire are piled up, and are highly 1.2~1.5m.Emergency lane is big upward slope dead end highway, and length is according to main line descending row
It sails (table 1) depending on speed, emergency lane longitudinal slope and slope aggregate.
1. emergency lane geometrical characteristic of table
According to available data introduction, domestic some emergency lanes, which are all not provided with, leads the way.It leads the way and plays connection main line and keep away
The effect in dangerous road can provide the sufficient reaction time to errant vehicle driver, and enough spaces are safely driven into along leading the way
Emergency lane is reduced because panic to driver's bring to lose control of one's vehicle.According to U.S.'s years of researches, the emergency lane of multilane
The length led the way be no less than 310m.
To guarantee brake failure vehicle secure parking before emergency lane end, the minimum length of emergency lane should be out of control
Minimum range needed for lorry parking.For upper shelving emergency lane, errant vehicle entrance velocity, emergency lane slope can be passed through
The coefficient of rolling friction etc. that degree, emergency lane gather materials, is calculated using kinematics formula.
L=V2/ [254 (i+Di)]
In formula, V drives into speed for vehicle；I is the gradient；Di is coefficient of rolling resistance, is shown in Table 2.
Coefficient of rolling resistance value between 2. tire of table and a variety of materials
| Material | Di value | Material | Di value |
| Portland cement concrete (PCC) | 0.01 | Loose rubble | 0.05 |
| Bituminous concrete | 0.012 | Loose gravel | 0.1 |
| The gravel of compacting | 0.015 | Sand | 0.15 |
| Loose soil containing sand | 0.037 | Beans molding sand gravel | 0.25 |
| Glass reinforced plastic pipe | 0.87 |
Present situation is that the emergency lane that the country is repaired can play the work for shunting errant vehicle from main line mostly
With, but the minor accidents such as the not guaranteed safety for driving into emergency lane driver, including scratch, cargoes from scattering and driver cause
The major accidents such as residual or dead all happen occasionally.
