Bridge construction method

Abstract

The invention relates to a bridge construction method, and relates to the field of bridge construction, wherein the bridge construction method comprises the following steps: S1, carrying out on-site investigation; S2, precast slab pouring: adopting concrete for conduct casting forming on precast slabs; S3, bridge pier pouring: carrying out pouring forming on a bridge pier by adopting a reinforced concrete structure; S4, laying of the precast slabs: laying the precast slabs through a tower crane; S5, pouring a concrete layer; and S6, laying an asphalt layer: laying the asphalt layer on the surface of the concrete layer. In the step S5, pouring of the concrete layer specifically comprises the following steps that: S5.1, fixing steel bars are mounted on the precast slabs, then a steel wire mesh is laid on the precast slabs, the steel wire mesh is flush with the surface of the concrete layer, and the steel wire mesh is fixed to the fixing steel bars; S5.2, concrete is poured on the surface of the precast slabs to form the concrete layer, and the concrete layer is flush with the top face of the steel wire mesh; and S5.3, the concrete layer is cured. The construction method has the effects that galling operation on the concrete layer before the asphalt layer is laid is avoided, and the construction efficiency of a bridge is improved.

Description

technical field [0001] The present application relates to the field of bridge construction, in particular to a bridge construction method. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas. They are structures that vehicles and pedestrians can pass through smoothly. In order to adapt to the modern high-speed development of the transportation industry, the current bridges are also extended to cross mountains, bad geology or meet other traffic needs. More convenient buildings. [0003] The existing Chinese patent whose publication number can be referred to is CN110886235A discloses a bridge construction method, which is characterized in that: comprising the following steps: a. site survey; b. pouring prefabricated slab; c. prefabricated slab maintenance; d. Fixing the reinforcement cage; e. Pouring the bridge pier; f. Installing the tower crane: installing the tower crane on the top of the two bridge piers; the tower arms o...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that before the asphalt layer is laid on the upper surface of the concrete layer of the bridge deck, it is necessary to use a concrete roughening machine to roughen the upper surface of the concrete layer of the bridge deck, which makes the construction process of the bridge very inconvenient and seriously reduces the improved construction efficiency
