Description
Technical field
It is more particularly to a kind of to can be used for the new road anti-collision facility construction of underground space ventilation the present invention relates to build,
Municipal Road Engineering anti-collision facility is combined as a whole with underground space engineering vented construction.
Background technology
At present, China is for the specification of road engineering anti-collision facility structure construction《Highway traffic safety facilities design is advised
Model》(JTG D81) and《Highway traffic safety facilities design detailed rules and regulations》(JTG/T D81), two kinds of specifications define four kinds of roads
Anticollision guardrail structure form, be respectively：Armored concrete wall, post and beam stiff safety fence, metal post and beam semi-rigidity rail, group
Box-like guardrail.Defined in specification in the case of four kinds of anticollision barrier specific constructive forms only account for meeting collision prevention of vehicle function
Structure structural form, do not consider the other functions purposes in addition to automobile collision preventing function is met.
Process and the continuous development of infrastructure construction with urbanization, especially in some underground spaces using preferable
Region, ground space resource is very limited, needs rationally to utilize ground space in road reformation, by constructing for the underground space
Thing is built together with road affiliated facility, therefore proposes requirement higher to the feature of road anti-collision facility.
In No. 7 line municipal administration conveyance system Wu Hou main roads overbridge engineerings of the subway that Chengdu is carried out, just encounter this
Situation.Because power pipe ventilation shaft is placed exactly under road center anticollision barrier, cause central anticollision barrier and ventilation shaft
Position conflicts, if by this section of ventilation shaft closing in region, ventilation shaft certainly will be caused to cause power channel ventilation to dissipate apart from excessive
Heat is bad.Therefore, also needed except to consider in addition to allowing anticollision barrier to meet collision prevention function when approach road section anticollision barrier is designed
Meet the ventilation and heat function of power channel.
Technical scheme
The technical problem to be solved in the present invention is to provide a kind of new road anti-collision facility that can be used for underground space ventilation
Construction, is met with having automobile collision preventing and underground space ventilation, two kinds of functions of radiating, and anti-collision level, ventilation and heat-sinking capability concurrently
Associated specifications requirement.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
The technical scheme that present invention solution above-mentioned technical problem is used is as follows：
A kind of new road anti-collision facility that can be used for underground space ventilation is constructed, including fixed underground space supply and exhaust are logical
The ordinary road anti-collision facility of road both sides, it is characterized in that：It is logical in underground space supply and exhaust between the ordinary road anti-collision facility
Road is fixedly installed steel construction anti-collision wall, and the steel construction anti-collision wall is in length direction by least two anti-collision facility unit spliceds
Into；Profile of the anti-collision facility unit on cross section is in herringbone, has rainproof ventilation from top to down in the height direction
