Description
Technical field
The present invention relates to a kind of road guard body of wall, particularly to a kind of concrete road guardrail body of wall and use this guardrail body of wall
Road guard.
Background technology
In recent years, along with highway in China construction and the fast development of transportation cause, mileage in highway open to traffic and vehicle population
Having had bigger growth, wherein large car ratio is continuously increased, and the situation is tense for Exploration on Train Operation Safety.At current China road traffic
In accident, vehicles traverse median strip is sailed into and is easily bumped against with opposed vehicle to track, causes the pernicious friendship on the dead group of group
Interpreter's event, is known as one of the most serious vehicle accident form both at home and abroad, brings greatly infringement to people life property safety.
And anticollision barrier is as a kind of safety devices, in terms of road traffic safety, play important protective action, for central strip
For band guardrail, anticollision barrier should possess higher degree of protection.
At present, widely used median barrier form includes corrugated beam barrier and concrete guardrail two kinds.The lowest etc.
Level corrugated beam barrier is limited for large car protective capacities, the most repeatedly occur a point band corrugated beam barrier in vehicles traverse sail into to
Track, cause the serious accident that the dead group of group hinders.If making corrugated beam barrier possess relatively high-protection level, steel using amount must be increased, build
Being set as this general to increase considerably, and later period maintenance replacing amount is relatively big, maintenance cost is higher, and cost performance is poor.And concrete protects
Hurdle is as stiff safety fence, and protective capacities is high and builds under the conditions of same degree of protection and maintenance cost is below steel guard rail, property
Valency is relatively good.But, in actual applications owing to its outward appearance is basically identical, moulding is stiff, the most penetrating, landscape effect and driving
Comfortableness is poor, easily causes driving fatigue, unfavorable to traffic safety, should improve its landscape effect.
General, prefabricated installation concrete guardrail respectively saves/section between connection mainly include that shaped steel connects, tongue and groove connects and power transmission
Bar (screw rod) connects.Its Shaped Steel connect, dowel steel (screw rod) type of attachment add guardrail install location and the later stage more
Change difficulty, simultaneously because use steel construction, be chronically exposed in external environment, be especially in the presence of and use winter Snow Agent to remove the snow
Region, the Steel section member that leaks outside easily is corroded, and largely effects on its mechanical property, reduces the integral protection ability of guardrail, and
And guardrail landscape effect can be destroyed further owing to the rust water after corrosion flows out.Tongue and groove is connected by tenon and embeds and contain tenon
Caulking groove in the form of connection, owing to being limited by barrier wall body thickness, general tenon and contain the chi of caulking groove of tenon
Very little can not be very big, cause its structural strength limited, become the weak link in guard bar structure, be normally only applicable to low protection etc.
The concrete guardrail structure of level, for the guardrail of high-protection level, owing to needed for guardrail, bearing capacity is relatively big, tongue and groove coupling part
Easily cause damage, destroy guardrail globality, make guardrail not reach Target Protection requirement.Execute additionally, tongue and groove connects to also exist
Work installation difficulty, damage after the not practical problem such as easy-maintaining.
