Road paving method

Abstract

The invention discloses a road paving method, which comprises the following steps: proofreading road building standard steel plates used as guard boards on both sides, adjusting to make it compatible with the horizontal line, and checking whether the thickness of the guard boards is consistent with the standards; installing a roller type road beam on the upper side of the guard board on the road paving starting position; blending a concrete slurry, pouring concrete on the position with height not more than 10 cm, and leveling with a shovel after pouring, wherein the pouring thickness is 2-4 cm higher than the guard board and pouring length is 0.5-1.5 m each time; rolling the road forwards with the road beam, then rolling backwards, and then rolling forwards; and before coagulation of the concrete pavement, using a dragging pressing plate of 2 cm thick and having a same width with the pavement to drag forward along the road direction. The method uses the low position pouring and reciprocating rolling to make the road strong and uniform in strength; the road treated by the dragging pressing plate is very smooth, so as to eliminate concave and convex potholes, prevent pavement damage, prolong the pavement life, and avoid slipping in heavy rain to ensure driving safety.

Description

technical field [0001] The invention relates to a building technology, in particular to a method for paving roads. Background technique [0002] During the road construction process, after the subgrade is completed, the road surface needs to be paved. At present, the usual practice is to wash down the concrete slurry at a certain height after the concrete is adjusted, in order to achieve a solid effect, and then use feet or sticks to poke or use vibrating plates to vibrate the concrete in order to increase the compactness of the concrete , Before the concrete sets, use a roller machine to make the road surface firm. However, after being washed down at a higher height, materials such as denser and larger stones will settle to the bottom, resulting in uneven concrete materials, resulting in insufficient hardness and strength of the surface layer, and reducing the quality of the road surface. The use of sticks to poke not only consumes a relatively large amount of labor, but ...

Problems solved by technology

However, after being washed down at a higher height, materials such as denser and larger stones will settle to the bottom, resulting in uneven concrete materials, resulting in insufficient hardness and strength of the surface layer, and reducing the quality of the road surface

Using sticks to poke not only consumes a lot of labor, but also leaves poking holes after poking, leaving pits on the surface, resulting in uneven road surfaces, and small pits are prone to appear later and soaked in accumulated water to damage the road surface

The vibration process of the vibrating plate and the rolling process of the roller machine can make the road surface stronger, but after the concrete is shaken, the road surface will always be uneven, easy to accumulate water, and it is also easy to cause bumps to passing vehicles, and the bumps and vibrations of the vehicles The reaction produces an impact on the road surface, thereby accelerating the damage to the road surface and reducing the service life of the road surface
