Description
Technical Field
The invention relates to the technical field of roadbed structures, in particular to an anti-settlement roadbed structure and a construction method.
Background
The roadbed is a strip-shaped structure which is used as a road foundation and is built according to a route position and a certain technical requirement, and is a linear structure built by soil or stones. When the roadbed is damaged by weather, hydrological conditions, human activities, geological movement and the like, the due firmness, stability and durability of the roadbed can be lost, the roadbed needs to be maintained frequently, time and labor are consumed, the waste of human resources is caused, the capital expenditure for roadbed maintenance is increased, the traffic and the use are hindered, and whether the roadbed can be normally used or not is directly related to roads and railways.
Aiming at the prior art, the roadbed is exposed in the external environment for a long time and is easy to be washed by rainwater, and the roadbed matrix is easy to be permeated by water and expanded or loosened to cause the instability of the roadbed. The road surface is easy to crack and sink, which is very unfavorable for driving safety. According to the technical standard of highway engineering published in 2014, roads are divided into five technical levels according to traffic volume. The vehicle speed can be divided into an expressway, an expressway and a common highway from the perspective of speed. The method is divided into national road, provincial road, county road, rural road and village road according to the administrative level. However, the settlement of the road subgrade is always a difficult problem, so that the service life of the road is greatly shortened, and a road structure for prolonging the service life of the road is improved.
Disclosure of Invention
In view of the problems in the prior art, the first object of the present invention is to provide a settlement-preventing roadbed structure with simple structure and practicality.
The second purpose of the invention is to provide a construction method of the anti-settlement road bed using the structure, which is simple to operate and use.
In order to achieve the first object, the invention adopts the following specific technical scheme:
