Description
Technical field
The invention belongs to technical field of road construction, and in particular to a kind of track that errant vehicle can be made slowly to slow down
Construction method.
Background technology
The one of the main reasons for causing major traffic accidents to lose control of one's vehicle, especially tell travelled on highway when, car
Fast general in 100-120km/h or so, vehicle is once out of hand in the state of such high speed will to lead to serious consequence.
Typically mainly caused to lose control of one's vehicle by blowing out with two kinds of reasons of brake failure, for blowing out, if driver's driving experience is rich
Richness, takes appropriate emergency operation still to reduce certain injury, and for brake failure this failure, driver is only
Vehicle can be waited to slow down naturally, or utilize emergency lane emergency deceleration.Traditional emergency lane be typically all by sandstone accumulation and
Into, vehicle enters after emergency lane, and the kinetic energy of car body is absorbed using the mobility of sandstone, so that vehicle deceleration, however,
In actual applications, gravel car road is poured under vehicle high-speed state still can produce larger instant impact, its buffering effect
It is limited, it is difficult to ensure the personal safety of driver, and sandstone track can make vehicle cause larger damage, vehicle is absorbed in sandstone
It is difficult to haul out, is that the processing of follow-up accident is made troubles.Errant vehicle can be made by devising one kind for this present inventor
The track slowly slowed down, thus also to have corresponding construction method matched.
The content of the invention
It is an object of the invention to provide efficient, the reliable track construction method of one kind, for car out of control can be made to one kind
The track slowly slowed down is constructed.

The through hole buried on girder steel (35) is corresponded, then the bottom surface of stopper slot (17) and the top surface of girder steel (35) are welded and fixed；
Step 9：Jack (16) and supporting plate (15) are installed on the girder steel (35) on the outside of stopper slot (17), and lay hydraulic tube
Road, fluid pressure line remains for the quick union of interim feed flow in advance；
Step 10：The install housing (18) on the outside of stopper slot (17).
2. the construction method in the track according to claim 1 that errant vehicle can be made slowly to slow down, it is characterised in that：Institute
