Abstract
The invention relates to an expressway medial strip concrete barrier transformation device which comprises two symmetrical concrete barrier bodies. Longitudinal beams are respectively arranged at top ends of the two symmetrical concrete barrier bodies. Positioning blocks are arranged on the inner sides of the longitudinal beams and located between the concrete barrier bodies. A cross support is arranged between the two symmetrical positioning blocks on the inner sides of the two concrete barrier bodies. The longitudinal beams and the positioning blocks are of an integrated structure. The problems that protection grade of the original barrier decreases because of rising of the surface of the expressway and protection requirements after reconstruction and expansion of the expressway cannot be met in the project of reconstruction and expansion of the expressway are solved. The expressway medial strip concrete barrier transformation device has the advantages of being convenient to process, convenient to install, cost-saving, capable of improving progress of works and lowering construction difficulties, suitable for transforming the medial strip concrete barrier in the project of reconstruction and expansion of the expressway and capable of effectively meeting protective requirements of the barrier.
Description
Technical field
The present invention relates to a kind of Expressway Central Strip concrete guardrail device for modifying.
Background technology
Need in Expressway Extension Project original express highway pavement is overlayed cover, and the road surface overlays the above highly reduction in road surface that cover makes original median strip concrete guardrail, protective capacities declines to a great extent before transforming, and is not enough to satisfy improved protection requirements.And the general construction period of Expressway Extension Project is comparatively nervous, if former median strip concrete guardrail is removed, can affect the road surface and overlay the cover construction, for construction organization and the higher reconstruction and extension project of schedule requirement and inapplicable, if former concrete guardrail integral cast-in-situ, guardrail dismounting difficulty is larger, and expense is high, length consuming time.
Therefore, keep former guardrail motionless, the median strip concrete guardrail device for modifying that only improves height more than the guardrail road surface by the mode that increases member on former guardrail top just seems very important.
Summary of the invention
The purpose of this invention is to provide a kind of Expressway Central Strip concrete guardrail device for modifying, reduce to overcome present existing guardrail grade that the difficulty such as the dismounting that brought and cast in situs are large, length consuming time, the high deficiency of expense.
The objective of the invention is to be achieved through the following technical solutions:
A kind of Expressway Central Strip concrete guardrail device for modifying, the concrete guardrail body that comprises two symmetries, the concrete guardrail body top of described two symmetries is equipped with longeron, the longeron inboard is provided with locating piece, locating piece is provided with stull between the inboard symmetrical locating piece of described two concrete guardrail bodies between two concrete guardrail bodies; Described longeron and locating piece are the integral type structure.
Further, the described longeron outside and the domatic smooth-going overlap joint of concrete guardrail body.
Further, described stull and longeron are the integral type frame construction.
Preferably, be provided with resistance outside described longeron and climb bank.
Preferably, described stull and longeron are separate type, and described stull is independent concrete prefabricated wedge structure.
Beneficial effect of the present invention is: can not satisfy the problem of reorganization and expansion rear protecting demand thereby the invention solves in Expressway Extension Project because road rises causes original guardrail degree of protection to descend, that this device has is easy to process, it is convenient to install, save cost, improve programming, reduce the characteristics of difficulty of construction, be specially adapted to that speedway is remodeled and expand in engineering original median strip concrete guardrail and transform, can effectively satisfy a kind of device of guardrail protection requirements.
