Concrete Pavement Crack Induction Method and Concrete Pavement Structure

Abstract

The invention relates to a concrete construction method, and discloses a concrete pavement crack induction method, which includes the following steps: S1, forming the following arrangement structure on the roadbed: arranging continuous reinforcements at intervals along the road width direction, and arranging multiple groups along the road surface extension direction a group of local reinforcements, wherein the local reinforcements in each group of local reinforcements are distributed between intervals of continuous reinforcements arranged at intervals, and the extension direction of the local reinforcements and the continuous reinforcements is consistent with the extension direction of the road surface, Crack inducers are correspondingly placed on each group of local reinforcements, and each crack inducer intersects with the local reinforcement and the continuous reinforcement; S2, filling concrete to form a concrete pavement. In addition, the invention also provides a concrete pavement structure. The method for inducing cracks on concrete pavement of the present invention can reduce the amount of reinforcing parts and reduce the cost of the whole project; the size of cracks and gaps will not be increased, and the cracks and gaps formed are relatively uniform.

Description

technical field [0001] The invention relates to a concrete construction method, in particular to a concrete pavement crack induction method. In addition, the invention also provides a concrete pavement structure. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. It is prepared according to a certain proportion by gel material, granular aggregate (also known as aggregate), water and, if necessary, admixtures and admixtures. It is a kind of artificial stone made by stirring, compacting and curing. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothe...

Problems solved by technology

Moreover, the location where cracks occur is a weak load area, and uncontrollable cracks will gradually widen or break under heavy traffic, affecting aesthetics and traffic

[0004] The method commonly used in the prior art to solve the above problems is to install crack inducers at appropriate positions in the concrete structure, and to arrange steel bars under the crack inducers. However, the methods provided in the prior art require a large number of steel bars, and the cost is relatively high, and The cracks formed are less uniform If the use of steel reinforcement is reduced, the cracks in the concrete pavement will increase
