Municipal water accumulation prevention road structure and construction method thereof

Abstract

The invention discloses a municipal water-accumulation-preventing road structure and a construction method thereof, relates to road construction, and aims to solve the problem that the service life of a road structure is shortened due to the fact that rainwater left on a waterproof bonding layer for a long time immerses into a base layer, the strength of the base layer is reduced, and the key point of the technical scheme is that the municipal water-accumulation-preventing road structure comprises the base layer, the waterproof bonding layer and a pavement layer, the top face of the base layer is provided with two inclined faces, the heights of the two inclined faces are gradually reduced from the middle of the base layer to the side edges, the waterproof bonding layer is attached to the two inclined faces and comprises two flow guide faces parallel to the inclined faces, the pavement layer is seamlessly laid above the flow guide faces, and the two sides of the base layer are each provided with a plurality of prefabricated drainage ditches. The side edge of the diversion face communicates with the inner side face of the prefabricated drainage ditch. By arranging the flow guide face, rainwater cannot be accumulated, and the rainwater can be quickly gasified and cannot permeate into the base layer, so that the structure of the base layer is effectively protected, and the service life of the municipal road is prolonged.

Description

technical field [0001] The present invention relates to highway construction, more specifically, it relates to a municipal road structure for preventing water accumulation and a construction method thereof. Background technique [0002] As the most important infrastructure in land transportation, roads and bridges can improve people's travel conditions and help the regional economy to develop accordingly. [0003] The existing municipal waterlogging prevention road structure often includes a base layer, a waterproof bonding layer and a pavement layer. During construction, a cement concrete layer (base layer) is poured on the road surface, and then a waterproof bonding layer is laid on the base layer. The asphalt mixture is paved on the waterproof bonding layer to form a pavement layer, thereby forming a rigid-flexible composite structure. The disease caused by the road structure has a great relationship with the failure and damage of the waterproof bonding layer. The design...

AI Technical Summary

Problems solved by technology

[0003] Existing municipal anti-flooding road structure often comprises base, waterproof bonding course and pavement layer, during construction, one deck cement concrete layer (base) is poured on road surface, then paving waterproof binding layer on base, then The asphalt mixture is paved on the waterproof adhesive layer to form a pavement layer, thereby forming a rigid-flexible composite structure. The disease of the road structure has a lot to do with the failure and destruction of the waterproof adhesive layer. The design of the junction layer and the selection of materials directly affect the service life of the road structure, and even affect the safety and durability of the road structure. Performance and life play a decisive role. Water is one of the most direct and important causes of road structure damage. After the existing waterproof adhesive layer encounters rainfall, the rainwater will stay on the top of the waterproof adhesive layer in large quantities. Until the water vaporizes and evaporates, the rainwater left on the waterproof adhesive layer for a long time will soak into the base layer, reducing the strength of the base layer, thereby shortening the service life of the road structure
