Abstract

The invention belongs to the technical field of highway bridge deck pavement construction, particularly relates to a bridge deck pavement surface crack control method, and solves problems that bridgeconstruction quality is seriously influenced, construction cost is increased and construction efficiency is reduced due to pavement layer surface cracking caused by defects of a traditional bridge deck pavement construction process. The invention comprises a claim 1 and the like. The method comprises the following steps that S1, bridge deck scum is removed, and residual concrete is chiseled away;S2, a reinforcing mesh protective layer is controlled; S3, concrete pouring control is performed; S4, surface finishing control is performed; S5, concrete covering and curing are performed; S6, linesare carved; and S7, false seam cutting is performed. Cracks generated on the pavement surface are effectively controlled, rework is not needed, the bridge construction quality is improved, the construction cost is greatly reduced, and the construction efficiency is improved; and flatness and overall appearance quality of bridge deck pavement are also ensured.

Description

technical field [0001] The invention belongs to the technical field of expressway bridge deck pavement construction, and in particular relates to a method for controlling surface cracks of bridge deck pavement. Background technique [0002] Bridge deck paving is to first pour a layer of cast-in-place concrete, then pave a layer of bridge deck waterproof material on top of the cast-in-place concrete, and finally pave a layer of asphalt concrete, and lay a layer of steel mesh when pouring concrete To form a protective layer of reinforced mesh, the distance between the reinforced mesh and the top surface of the cast-in-place concrete is the thickness of the upper layer L2, and the distance from the bottom surface of the cast-in-place concrete is the thickness of the lower layer L1 (such as figure 2 shown). [0003] When pouring a layer of cast-in-place concrete, the most common construction defect is the appearance of cracks of varying degrees on the surface after the construc...
