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 comprises the following steps: S1, forming the following arrangement structure on a roadbed: arranging continuous reinforcements at intervals along the road width direction, and arranging a plurality of local reinforcement groups along the pavement extension direction, the localreinforcing pieces in each local reinforcing piece set are arranged between the intervals of the continuous reinforcing pieces arranged at intervals in a scattered mode, the extending direction of thelocal reinforcing pieces and the extending direction of the continuous reinforcing pieces are consistent with the extending direction of the road surface, and crack inducing pieces are correspondingly placed on the local reinforcing piece sets, and each crack inducer is crossed with the local reinforcer and the continuous reinforcer; and S2, filling concrete to form a concrete pavement. In addition, the invention further provides a concrete pavement structure. The concrete pavement crack induction method has the advantages that the use amount of reinforcements can be reduced, and the cost ofthe whole project is reduced; and the sizes of the cracks are not increased, and the formed cracks are 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
