Description
Technical field
The present invention relates to roadbed concrete guardrail to recycle construction method, belongs to traffic safety protection field.
Background technology
In recent years, China's expressway construction was fast-developing, and building up and runing for highway greatly facilitates the masses
Trip and various regions on the way economic development.But with China's economy rapid growth and highway transportation cause flourish,
The volume of traffic increases rapidly, and particularly large truck increases, and directly results in highway communication facility frequency of use and load
Increase, the highway much built in early days can not adapt to the operation demand of the current volume of traffic, according to incompletely statistics,
In the highway built before 2004, about 30,000 kilometers have been enter into the reorganization and expansion stage.
At present, so needing to set substantial amounts of temporary guard rail, it is used for often using " protecting logical " policy in reconstruction and extension project
Ensure construction area safety.Temporary guard rail is divided into prefabricated and cast in situs, precast concrete guardrail foundation anchor power Shortcomings, leads
Cause guardrail barrier propterty relatively low, poor, security protection scarce capacity is protected to oversize vehicle；A point band concrete protects in cast-in-place roadbed
Column concrete foundation is connected firmly, and can reach compared with permanent protective property energy, but construction method is complex, is not easy in the case of " protecting logical "
Site operation, and it is usually that destructiveness is removed to be removed after installing, not reproducible utilization.
Based on this, propose that a kind of roadbed concrete guardrail recycles construction method.
The content of the invention
The present invention proposes that a kind of roadbed concrete guardrail recycles construction method, roadbed concrete guardrail is had cast-in-place work concurrently
The security protection performance of skill guardrail and the convenient of precasting process guardrail remove locomotive function, realize that the repetition of concrete guardrail is sharp again
With the temporary guard rail that can be applied not only in reconstruction and extension project, could be applicable to newly-built road, greatly extend the use of guardrail
In the life-span, the waste of material in engineering construction is reduced, and meet security protection demand, met " resources conservation and environmental protection "
Engineering construction theory.
To achieve the above object, technical scheme is as follows：
The roadbed concrete guardrail recycles construction method specific steps：
(1) prefabricated fabrication of concrete prefabricated section；
(2) concrete precast block is assembled, and adjustment is linear, connects longitudinal connecting component, forms temporary guard rail；
(3) when dismantling guardrail, longitudinal connecting component is first opened, is then removed concrete precast block standby；
(4) concrete precast block is recycled and is installed as in roadbed a point band guardrail；
Further, the step (1)：Guardrail reinforcing bar built in concrete precast block and longitudinally connected preburied component, when
During the two position conflict, it should ensure that preburied component position is constant, suitably adjust reinforcement location.
Further, the step (2)：Connection concrete precast block between it is longitudinally connected after lie against road surface, concrete
Prefabricated section is connectionless with road surface.
Further, the step (3)：Can not be to coagulation during opening connecting elements and removing concrete precast block
Native prefabricated section causes transition to damage with preburied component.
Further, the step (4)：After paved road basic unit, line setting installs leveling layer, and installation concrete is pre-
Clamp dog, adjustment it is linear, and complete it is longitudinally connected, concrete precast block back install cross-brace block, installation guardrail correlation it is attached
Belong to facility, highway surface layer of finally mating formation.
Further, the step (4)：After paved road basic unit, line setting, mounting groove is reserved, public affairs of mating formation afterwards
Supercrust, in installation trench bottom installation leveling layer, standby concrete precast block being positioned in mounting groove, adjustment is linear, and
Complete it is longitudinally connected, concrete precast block back install cross-brace block, finally install guardrail associated satellite facility.
Further, construction muscle should be matched somebody with somebody when the leveling layer is excessive.
Compared with prior art, beneficial effects of the present invention
The roadbed concrete guardrail of the present invention recycles construction method, increases a point band concrete guardrail in roadbed and recycles
Rate, general general work will soon grasp work progress, easy construction, cost-effective, environmental protection.
The roadbed concrete guardrail of the present invention recycles construction method, and guardrail wall body structure is not destroyed in work progress, protects
The integrality and intensity of concrete precast block are demonstrate,proved.
The roadbed concrete guardrail of the present invention recycles construction method, and concrete precast block can be used for multiple times, and use the longevity
Life length, it is easy to maintain.
The roadbed concrete guardrail of the present invention recycles construction method, and concrete guardrail prefabricated section can be used for multiple times, make
It is easy to maintain with long lifespan.
