The utility model discloses during the construction, prefabricated section can regard as the exterior sheathing of the cast-in-place partial construction of guardrail, the integrative prefabricated delivery pipe backup pad in prefabricated section outside, and the lamp pole basis is done concurrently to the guardrail, has reduced the space and has occured on the bridge, has saved delivery pipe support installation process, can reduce construction cost for the construction progress.
Description
Technical Field
The utility model belongs to the technical field of the concrete bridge construction, the construction of the affiliated facility of design bridge floor, concretely relates to multi-functional bridge anticollision barrier.
Background
The bridge deck auxiliary facilities comprise crash barriers, street lamp posts, cable pipelines, water supply (drainage) pipes and the like. The above-described sub facilities are usually constructed separately, involving a plurality of processes. The anti-collision guardrail is constructed by adopting reinforced concrete cast-in-place, an operation platform installation template needs to be erected outside the bridge in the construction process, and overhead edge operation has certain risks; the lamp posts on the bridge are required to be embedded and installed according to the designed positions, and part of the space on the bridge is occupied; the cable pipe and the water supply (discharge) pipe need to be erected with special supports, which occupies a large amount of labor resources and equipment resources in construction and increases construction cost.
Disclosure of Invention
The utility model aims at providing a multi-functional bridge anticollision guardrail to the current situation that current bridge floor subsidiary facility construction process is many, the construction risk is big, occupation space is many, with the integration of multiple subsidiary facility on the guardrail, reduce and occupy the bridge floor space to simplify construction process, reduce construction cost.
The technical scheme of the utility model as follows:
the utility model provides a multi-functional bridge anticollision barrier which characterized in that: the guardrail is provided with a prefabricated section facing the outer side of the bridge and a cast-in-place section facing the inner side of the bridge; the lower part of the inner side of the prefabricated section is supported on a bridge flange plate, and the outer side of the prefabricated section is provided with a water supply pipe supporting plate integrally cast with the prefabricated section; the bottom of the cast-in-place section is poured on a bridge flange plate, the cast-in-place section and the prefabricated section are poured into a whole, and a cable pipe is arranged between the prefabricated section and the cast-in-place section along the bridge direction; the top of the prefabricated section and the top of the cast-in-place section are provided with embedded bolts and are connected with a street lamp pole through the embedded bolts.
The utility model reduces the high-altitude edge construction risk and the construction cost by prefabricating the guardrail part and using the prefabricated part as the outer template for the construction of the guardrail cast-in-place part; the outer side of the guardrail is provided with the water supply pipe supporting plate which is integrally cast with the prefabricated part of the guardrail, so that the construction process of a water supply pipe mounting bracket is reduced, and the construction progress can be accelerated; the guardrail is also used as a lamp post foundation, and the cable pipe is embedded in the guardrail, so that the space occupation on the bridge is reduced.
Drawings
FIG. 1 is a cross-bridge elevation of the present invention;
fig. 2 is a schematic view of the construction state of the present invention on a bridge.
Detailed Description
As shown in fig. 1, the multifunctional bridge anti-collision guardrail provided by the utility model is a prefabricated section 1 facing the outside of the bridge and a cast-in-place section 2 facing the inside of the bridge; the lower part of the inner side of the prefabricated section 1 is supported on a bridge flange plate 3, and the outer side of the prefabricated section is provided with a water supply pipe support plate 4 integrally cast with the prefabricated section; the bottom of the cast-in-place section 2 is poured on a bridge flange plate, the cast-in-place section and the prefabricated section are poured into a whole, and a cable pipe 5 is arranged between the prefabricated section 1 and the cast-in-place section 2 along the bridge direction; the top of the prefabricated section and the top of the cast-in-place section are provided with embedded bolts 6 which are connected with a street lamp pole 7 through the embedded bolts.
As shown in fig. 2, the construction process of the present invention is as follows:
(1) when the construction flange plate 3 is constructed, a guardrail cast-in-place section steel bar 8 is arranged at the same time;
(2) prefabricating a guardrail prefabricating section 1 in an yard, prefabricating a water supply pipe supporting plate 4 integrally outside the prefabricating section, embedding connecting steel bars 9 in the prefabricating section, and arranging 2 street lamp pole embedding bolts 6 at the top corresponding to each street lamp position;
(3) hoisting the prefabricated section 1 onto a bridge flange plate 3, fixing the prefabricated section with a cast-in-place section steel bar 8 on the flange plate through a connecting steel bar 9 on the inner side of the prefabricated section, and using the prefabricated section as an outer side template for the subsequent cast-in-place section construction;
(4) a PVC cable pipe 5 used for supplying power to a street lamp and the like is arranged between the prefabricated section and the cast-in-place section;
(5) erecting a template at the inner side of the cast-in-place section, casting the cast-in-place section 2, positioning the top of the cast-in-place section through 2 lamp post connecting bolts on the prefabricated section during casting, and embedding another 2 lamp post embedded bolts 6;
(6) after the strength of the cast-in-place section concrete reaches the design strength, a light pole 7 is installed at the top of the guardrail, and a water supply pipeline 10 is installed on the water supply pipe supporting plate 4.
Therefore, the utility model discloses a construction of multi-functional guardrail is accomplished. Compare current bridge floor auxiliary structure construction, saved guardrail exterior sheathing, saved light pole installation space, still saved delivery pipe support and installation procedure.
