A road surface structure near water and its construction method

Abstract

The invention discloses a near-water pavement structure and a construction method thereof, comprising an asphalt surface layer, a porous drainage base layer is arranged under the asphalt surface layer, a concrete layer is arranged under the porous drainage base layer, and a concrete layer is arranged under the concrete layer There is a first waterproof layer, and a gravel cushion is arranged under the first waterproof layer; a plurality of water-passing round culvert pipes are arranged in the sand-gravel cushion, and the leaking pipes are connected with the water-passing round culvert pipes. A concave filter screen is arranged in the ring; a top ball is fixedly arranged on the side of the push rod close to the concave filter screen, and a floating ball is fixedly installed on the side of the push rod close to the water passing circular culvert pipe. The invention provides a near-water road surface structure, which can timely guide the accumulated water passing through the road surface and road section, and can automatically trigger the early warning device when the water level is too high or the water-passing round culvert pipe is blocked by mud, which attracts the attention of maintenance personnel. The invention also discloses a construction method based on the near-water pavement structure, which is easy to operate and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of pavement construction, in particular to a near-water pavement structure and a construction method thereof. Background technique [0002] In the prior art, the application number is "201720747310.9", a crack-resistant and waterproof pavement base, including a limestone-gravel mixture sub-base, a cement-stabilized graded gravel base, and a synchronous gravel base that are successively laid on the roadbed from bottom to top. Sealing layer, AC-25C asphalt concrete lower layer, high-viscosity modified asphalt stress-absorbing layer, AC-13C modified asphalt concrete upper layer, the high-viscosity modified asphalt stress-absorbing layer is covered with polyester oil-impregnated reinforced cloth , the cement-stabilized graded macadam base used in the anti-cracking and waterproof pavement base has good stress dispersion performance, shear resistance and rutting resistance, temperature insulation, moisture insulat...

AI Technical Summary

Problems solved by technology

[0003] However, there are still relatively obvious defects in its use: 1. The base layers of the above-mentioned road surface are all arranged in parallel, which is very unfavorable for water diversion, and it is easy to cause water to accumulate on the road surface and cause erosion on the road surface and damage, over time it will significantly reduce the skid resistance of the road surface and affect driving safety; 2. There is no water round culvert pipe in the base layer of the above road surface, so that the cross section of the water inlet will always be eroded by accumulated water and cannot be effectively diverted. It will erode the overall stability of the pavement; 3. The water-conducting and waterproof performance of each base layer of the pavement will gradually decrease with the service life. The above-mentioned pavement structure lacks relevant early warning devices, and the pavement may suddenly crack and scour, causing great hidden dangers; 4. In the hot summer, the concrete layer will be crushed or arched at the edge due to the rise in temperature, while in the cold winter, the concrete layer will shrink irregularly due to the drop in temperature. The above pavement structure lacks the necessary response Buffer structure, which will cause deformation of the road surface
