Problems solved by technology

[0003] The device used for paving cement pavement in the prior art is relatively heavy and cannot be adjusted according to the width of the pavement; in the process of laying the pavement, it is necessary to evenly distribute the cement concrete accumulated in the middle of the pavement, so that the two sides of the pavement and the middle of the pavement The height of the cement concrete is consistent, and the cement concrete needs to be leveled to reduce the hollowing phenomenon in the cement concrete; the road surface needs to be smoothed according to the height of the road surface

Abstract

The invention relates to the technical field of road and bridge construction and especially relates to a pavement cement paving device for road and bridge construction. The device comprises ground beam seats which are symmetrically paved on two sides of a road surface. Bottom plates are arranged at the tops of the ground beam seats. Cases are welded to the tops of the bottom plates. The bottom ofa main rod extends below a main plate block and is welded with an E-shaped frame; a vertical plate is mounted at a front end of the E-shaped frame; a flow guide block for pushing cement concrete towards two sides of the road surface is fixed in the middle of the front end of the vertical plate; two L-shaped square pipes are arranged in the middle of the bottom of the main plate block; rake teeth for raking cement concrete are uniformly arranged at the bottom of the L-shaped square tube; and inner rods are elastically installed at the bottom of an outer pipe, a paving plate is jointly installedat the bottoms of the two inner rods, and pressure applying cylinders are evenly arranged at the top of the paving plate. The device is ingenious in structure, the cement concrete stacked in the middle of a road surface is pushed to the two sides of the road surface through the arrangement of the flow guide block, and the road surface is flattened through the arrangement of the rotating L-shapedsquare pipes; and the road surface is flattened through the paving plate so that a pavement paving effect is good.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a pavement cement paving device for road and bridge construction. Background technique [0002] Existing highway pavement is generally cement pavement or asphalt pavement, and cement concrete pavement refers to a pavement with cement concrete as the main material for the surface layer, referred to as concrete pavement. Also known as rigid pavement, commonly known as white pavement, it is a high-grade pavement. With the development of my country's transportation industry and the continuous improvement of road performance, the requirements for road surface roughness are getting higher and higher for road construction. Road surface roughness is the most important indicator of road performance. [0003] The device used for paving cement pavement in the prior art is relatively heavy and cannot be adjusted according to the width of the pavement; in the process of ...
