Barrier-free base construction method for urban roads

Abstract

The invention discloses a barrier-free base construction method for urban roads. The construction process of the barrier-free base construction method comprises the following steps: preparation before construction, construction-parameter determination, spreading, rolling, treatment of an inspection well, joint treatment, maintenance and traffic control. The barrier-free base construction method disclosed by the invention has the advantages that the construction is convenient, and the construction effect is good; the same height of the inspection well and a road bed in spreading is ensured, so that no barrier exists on the road in spreading; simultaneously, the continuous supplying is adopted, so that the construction efficiency is greatly improved; the adopted technology is advanced, the safe and reliable effects can be achieved, and the economic benefit and the social benefit are obvious, so that the barrier-free base construction method is worthy of being promoted and applied.

Description

technical field [0001] The invention relates to a construction method, in particular to an urban road barrier-free base construction method. Background technique [0002] With the improvement of urbanization level, the expansion of city scale, the increasing number of urban drainage pipes and inspection wells, the drainage problem in cities has become more and more concerned. The existence of inspection wells directly affects the integrity of roads, structural stability and At the same time, it also has a great impact on the service life and comfort of the road. The problems in the construction and use of inspection wells have become the current concerns. Improper construction causes uneven settlement of the road surface and leads to damage. On the other hand, during construction If its characteristics are not fully utilized, the construction efficiency will be reduced and the cost will be increased. At the same time, with the acceleration of urbanization and the improvemen...

Problems solved by technology

[0006] 2. Damage to the road surface around the well: There are horizontal and vertical cracks in different degrees on the road around the inspection well, and the cracks spread to the surroundings and gradually break down. Exacerbating potholes in the road

[0008] In view of the above-mentioned problems of the inspection well, in addition to the inspection well itself, the more important thing is the defect of the road construction method. During the paving construction of the traditional urban road base, in order to ensure that the inspection well is not damaged, the height of the inspection well is built at one time. , which leads to the protruding inspection well that hinders the work of the paver and the rolling machine when paving the road. At the same time, the mixture around the inspection well cannot be compacted by the rolling machine and needs to be tamped manually , but the degree of compaction of the manual tamping pair is difficult to meet the requirements, resulting in wheel sinking around the inspection well. During the paving process, the machine keeps shutting down and starting up, causing waves to form on the road, which can easily cause driving bumps, damage the road surface and reduce construction efficiency
