Problems solved by technology

[0003] At the same time, in the hot season, due to the long-term direct sunlight, the temperature of the highway surface rises sharply, which not only reduces the service life of the highway, but also causes vehicle tire bursts due to high temperature; and in winter, snow and ice on the road are difficult to Removal, it also brings great inconvenience to the normal driving of vehicles, and often causes serial rear-end collision accidents due to road ice accumulation, which is not conducive to ensuring the safety of people's lives and property

Embodiment Construction

[0033] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0034] Such as figure 1 with Figure 7 Shown, a kind of expressway maintenance method of the present invention, this method comprises the following steps:

[0035] S1, spray a layer of hydrophobic material on the road surface of the expressway, and the hydrophobic material can prevent rainwater from soaking into the expressway;

[0036] S2, on the basis of S1, install the drainage device on the car, and the car carries the drainage device to clean up the accumulated water on the highway;

[0037] S3, in hot weather, on both sides of the expressway, set water wells at equal intervals along the length of the expressway, use water pumps to pump out groundwater and spray it on the road surface;

[0038] S4, on the basis of S3, on both sides of the ...

Abstract

The invention relates to the technical field of road maintenance, in particular to an expressway maintenance method. The method realizes the smoothness of the expressway by setting water wells on bothsides of the expressway, then cooling the pavement or heating the water through the water, and melting snow and ice through the hot water. By installing the drainage device on the vehicle, the methodcan realize timely drainage of the accumulated water on the low-lying pavement of the expressway, thereby avoiding rainwater infiltration and prolonging the service life of the expressway.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to a highway maintenance method. Background technique [0002] The expressway is a high-grade highway, which can adapt to the speed of 120 km / h or higher. The road surface has a width of more than 4 lanes, with a divider in the middle, using asphalt concrete or cement concrete high-grade pavement, with complete signs, Markings, signals and lighting devices, the drainage system in the expressway is particularly important. When the drainage pipe is blocked, the rainwater is easy to accumulate on the road surface, and the rainwater soaks into the road surface for a long time, making the road surface soft. This makes the road surface here lower and lower relative to the surrounding road surface, which has a greater impact on the highway road surface. [0003] At the same time, in the hot season, due to the long-term direct sunlight, the temperature of the highway surface rises...
