Municipal bridge construction concrete pavement pouring forming process

Abstract

The invention relates to a municipal bridge construction concrete pavement pouring forming process. The process uses filling equipment, the filling equipment comprises a base, a stirring device, a joint filling device and an adjusting device. The municipal bridge construction concrete pavement pouring forming process concretely comprises the steps that: the stirring device is placed on the upper surface of the base, the joint filling device is arranged at the left side of the lower surface of the stirring device, and the adjusting device is arranged at the lower part of the inner cavity of thejoint filling device. According to the filling equipment, an acceleration motor is started, so that a push rod moves back and forth in the inner cavity of a fixed box, a joint is filled by the jointfilling device, and an overturning motor is started to drive a scraping shaft to rotate, so a scraping plate scrapes off concrete pasted on an arc-shaped rotating plate; and through control over rotation of a two-way threaded rod, a moving block on the two-way threaded rod moves, and then filling is conducted according to different widths of gaps generated in a concrete pavement.

Description

technical field [0001] The invention relates to the field of pavement pouring, in particular to a concrete pavement pouring molding process for municipal bridge construction. Background technique [0002] Urban bridges refer to bridges built on rivers, road and road overpasses, overpasses and pedestrian bridges where roads cross railways within the city limits, including permanent bridges and semi-permanent bridges, excluding temporary bridges, railway bridges, and culverts; [0003] Concrete pavement refers to the pavement with cement concrete slab as the surface layer. It refers to the pavement structure composed of cement concrete slab as the surface layer, base layer and cushion layer, also known as rigid pavement; [0004] Due to the long-term effect of the external environment on the concrete pavement, the aging of the material, or due to the thermal expansion of the slab, the pavement will appear cracked and cracked. It is restored to level and is convenient for pede...

AI Technical Summary

Problems solved by technology

[0005] (1) Since the gaps on the concrete pavement are being filled, the ratio of the amount of concrete lowered by the general filling device when concrete blanking is easy to make the amount of concrete lowered too much, making it difficult to fill the gaps;

[0006] (2) Since the concrete is viscous, it is easy to cause adhesion at the discharge port, and the concrete cannot fall completely, which will affect the use of the caulking device over time;

[0007] (2) Due to the different degrees of damage on the road surface, the width of the gaps in the concrete pavement is also different, and the filling devices on the market cannot fill up the width of the gaps;
