Bridge road provided with combined side guardrails and construction method of bridge road

Abstract

The invention discloses a bridge road provided with combined side guardrails and a construction method of the bridge road, and relates to the technical field of bridge engineering construction. The bridge road comprises a beam body and the combined side guardrails; the combined side guardrails comprise a plurality of guardrail units which are sequentially connected in the bridge direction, each guardrail unit comprises an outer side guardrail and an inner side guardrail, wherein each outer side guardrail is a prefabricated guardrail of an integrated structure, at least two cantilever supportsare embedded in the outer side guardrail, and the two cantilever supports are both connected to the upper surface of the beam body in a hung manner, so that the outer side guardrail can be suspended on the side of the beam body; and each inner side guardrail is a cast-in-place guardrail, the outer side faces of the inner side guardrails are attached to the inner side faces of the outer side guardrails, the lower surfaces of the inner side guardrails are attached to the upper surface of the beam body, and the inner side guardrails are connected to the cantilever supports in wrapping and hangingmanners. According to the bridge road, a semi-prefabricated and semi-cast-in-place manner is adopted, the prefabricated outer side guardrails serve as pouring formworks of the cast-in-place inner side guardrails, the combined side guardrails are installed on the sides of the bridge road, the problem that outer formworks of the side guardrails are difficult to install is solved, and the construction efficiency is effectively improved.

Description

technical field [0001] The application relates to the technical field of bridge engineering and construction, in particular to a bridge highway equipped with combined side guardrails and a construction method thereof. Background technique [0002] Bridges and roads are designed with road side guardrails, which can be used as safety retaining walls and can also beautify the overall appearance of the bridge. At present, the general bridge road side guardrail is to install the inner and outer guardrail templates on the road bridge deck, and use the integral pouring method to make the side guardrail, or prefabricate the side guardrail in the prefabrication factory, and then install it on the road bridge deck. [0003] However, as far as the overall cast-in-place side guardrail is concerned, the positioning and installation of the outer mold need to be realized by erecting a cantilever platform or installing a hanging basket, which has slow construction and high potential safety ...

AI Technical Summary

Problems solved by technology

[0004] The embodiment of the present application provides a bridge road with a combined side guardrail and its construction method. The semi-prefabricated and semi-cast-in-place form is adopted, and the prefabricated outer guardrail is used as the pouring formwork for the cast-in-place inner guardrail. The installation of combined side guardrails solves the problem of difficult installation of the outer formwork of the side guardrails and effectively improves construction efficiency
