Assembly-type kerb capable of automatically discharging water of asphalt pavement and construction method of kerb

Abstract

The invention relates to the technical field of kerb construction, and discloses an assembly-type kerb capable of automatically discharging water of an asphalt pavement and a construction method of the kerb. The kerb comprises an impermeable base plate and impermeable kerbstone, a permeable layer of a pore structure is arranged at the portion, in the longitudinal direction of the kerb, of the upper surface of the base plate, and the upper surface of the permeable layer is lower than the upper surface of the kerbstone to form a flow guide corner for gathering pavement accumulation water; a preformed hole which is distributed in the longitudinal direction of the kerb is arranged at the portion, close to the kerbstone, of the junction of the permeable layer and the base plate, and runs through mounting faces at the two ends of the kerb, a flexible permeable pipe is arranged in the preformed hole, and vertical flowing water and transverse flowing water permeating the permeable layer flow into the flexible permeable pipe to be discharged. The kerb has the advantages that the pavement accumulation water is automatically and quickly discharged, accumulation water in the asphalt pavement is effectively discharged, and connection and mounting are stable. The construction method is simple, and the asphalt pavement has a discharge effect after adopting kerb construction.

Description

technical field [0001] The invention relates to the technical field of curb stone construction, in particular to a curb stone for an assembled self-draining asphalt pavement and a construction method thereof. Background technique [0002] Curb stones are strip structures that separate road surfaces and shoulders in road engineering, such as figure 1 As shown, the separation of the asphalt pavement layer and the road shoulder by the curb is beneficial to the respective division of labor between the pavement and the road shoulder on the road. Asphalt pavement is widely used in road engineering because of its good driving feeling and fast maintenance speed. The road shoulder is located on the outer edge of the roadway and the edge of the roadbed, and the road shoulder has a certain width of the belt structure, including hard shoulders and soil shoulders. The role of the shoulder is mainly to protect the stability of the roadway, provide lateral margins for driving safety, and...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to address the deficiencies in the prior art, to provide a curb stone of assembled self-draining asphalt pavement and its construction method, which has the effects of good drainage of the road surface, stable driving on the road surface, and satisfying the separation function, etc., and solves the existing problems. The slow drainage of the curb stones in the technology leads to the soaking of the road surface, the extrusion of the water in the asphalt pavement layer by the vehicle load affects the service life of the asphalt pavement, and the connection of the curb stones by plastering cement mortar is easy to cause cracks in the joint joints, which is not conducive to drainage other difficult questions
