Municipal road and construction operation method

Abstract

The invention provides a municipal road and a construction operation method. The municipal road is characterized in that the municipal road is provided with a road body structure, the left and right sides of the road body structure are provided with guardrail grooves, the guard grooves are used for mounting retractable road guardrails, the inner sides of the guardrails are provided with arc drainage grooves, and drainage filter devices are mounted in the arc drainage grooves. The municipal road of the invention has the advantages of simple overall structure, high safety factor, good comprehensive bearing capacity of the road surface and the like. In addition, for specific implementation, the municipal road and the construction operation method of the invention have the advantages of shortimplementation cycle, simple construction process and good construction effect.

Description

technical field [0001] The invention relates to a municipal road, in particular to a municipal road and a construction operation method. Background technique [0002] Pavement materials often used in road construction are mixtures of cement, sand, etc., and water. The construction of pavement materials is generally stopped under low temperature conditions below 5°C, because in this case, the water and sand materials in the pavement materials are easy to condense. , although the compressive strength and tensile capacity of the pavement material are increased to a certain extent, but once the temperature rises, the condensation in it dissipates, making the strength of the pavement material significantly lower; and a series of problems will also appear in pavement construction under low temperature The problem is that due to the rapid temperature loss, the pavement is difficult to pave and compact due to the large internal void ratio and large water seepage coefficient of the p...

Problems solved by technology

However, since urban roads are generally paved with concrete, the road surface is prone to water accumulation in rainy days, and the interconnected cover plates block the drainage channels, resulting in a large amount of water accumulation on the road surface

[0007] For municipal roads, the free water in the cracks of the pavement will generate considerable hydrodynamic pressure under the action of the driving load, and the pressure water will continuously wash away the fine materials in the base material, and the fine material slurry will be gradually squeezed out of the cracks. Once the fine slurry is pumped out, the asphalt surface will sink along the cracks, and at the same time, new cracks will be caused on both sides of the cracks, resulting in cracks on both sides of the pavement cracks, and gradually Causes extensive damage to the road surface, thereby shortening the service life of the road and being easily damaged by expansion

[0008] In addition, as far as the existing municipal road structure is concerned, the structural construction is difficult and the comprehensive performance is poor. At present, there are few researches on the design and construction technology of road reconstruction and expansion in China, and most of them only stay at the level of technical analysis of the construction of a single project
