Pavement slab

Abstract

The invention discloses a pavement slab. The pavement slab comprises a base layer and a protective layer which is covered on the base layer, wherein the base layer is formed by combining a plurality of supporting plates in the same plane; connecting pieces matched with each other are arranged on at least one group of corresponding sides of the supporting plates; and two adjacent supporting plates are fixedly connected with each other. The pavement slab is laid on the road, and the pavement bearing capacity is improved; the pressure acting on the pavement slab can be uniformly dispersed through the pavement slab, the phenomenon that the ground is extruded to be damaged due to the stress at a single position is avoided, and the using cost is reduced; the hardness of the pavement is improved, and the horizontal driving vehicle speed is improved; and moreover, because the pavement slab comprises the base layer and the protective layer, the protective layer has the function of effectively preventing the base layer from being damaged, and the using cost of the base layer plate is reduced.

Description

technical field [0001] In particular the invention relates to a paving slab for laying on the ground. Background technique [0002] Due to the frequent productive operations of traditional agricultural production machine-plowed roads, the soil is generally soft, and deep ruts are often left when the locomotive is running, especially in rainy days. The rut formation is more obvious when the soil becomes hard after the weather is dry , Often can make the unevenness of the road surface, affect driving, and cause corresponding safety hazards. [0003] Generally, on some lake defense dams, due to the uneven hardness of the soil, the depth of the ruts formed is different, and the locomotive will shake when it is running, resulting in a greater possibility of overturning. [0004] In addition, after laying road slabs on the road surface, it is difficult to re-cultivate the machine-plowed roads on which the slabs are laid, and the cost of re-cultivation is high, especially for some...

AI Technical Summary

Problems solved by technology

[0002] Due to the frequent productive operations of traditional agricultural production machine-plowed roads, the soil is generally soft, and deep ruts are often left when the locomotive is running, especially in rainy days. The rut formation is more obvious when the soil becomes hard after the weather is dry , often creates unevenness on the road surface, which affects driving and causes corresponding safety hazards

[0003] Generally, on some lake defense dams, due to the uneven hardness of the soil, the depth of the ruts formed is different, and the locomotive will shake when it is running, resulting in a greater possibility of overturning.

[0004] In addition, after laying road slabs on the road surface, it is difficult to re-cultivate the machine-plowed roads on which the slabs are laid, and the cost of re-cultivation is high, especially for some roads paved by temporary operations, it is difficult to remove the slabs after the project is completed. waste of land resources

[0005] In order to avoid the problem of potential safety hazards caused by unsatisfactory roads when locomotives are running, a paving slab that can strengthen the bearing strength of the ground and ensure driving safety is urgently needed.
