Roadbed earthwork reinforcing method for highway engineering

Abstract

The invention discloses a roadbed earthwork reinforcing method for expressway engineering, which comprises the following steps of: 1, uniformly paving an earthwork mixed material at the upper end of aroadbed bottom platform, covering clay at the upper end of the paved earthwork after the earthwork is paved; then the clay being continuously laid on the two sides of the earth-rock laying position to form an oblique wave structure for reinforcing the earth-rock; 2, an accurate angle measuring instrument being used for building an oblique wave angle laid by clay into an oblique angle of 45 degrees, then concrete being poured at the starting end and the tail end of the oblique wave structure, then a grounding pile being transversely installed outside the oblique wave, and an embedded pit needed for installing the grounding pile being dug in a roadbed bottom table in advance. According to the highway subgrade reinforcing structure, the effect of reinforcing a highway subgrade by adopting earthwork materials is achieved, the firmness and weather resistance of the subgrade are effectively improved, and the problem that the subgrade is eroded by sandstorm after being exposed to the naturalenvironment for a long time is solved.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a roadbed earthwork reinforcement method for expressway engineering. Background technique [0002] Highway engineering refers to the investigation, measurement, design, construction, maintenance and management of highway structures. Highway engineering structures include: subgrades, road surfaces, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring, early construction, Maintenance work is generally done with simple tools and manpower or animal power. With the development of the machinery industry, power machinery such as steam engines and internal combustion engines are widely used in construction, and various single-purpose machinery and combined operation machinery appear. Among the road cons...

AI Technical Summary

Problems solved by technology

[0003] The existing expressway engineering roadbed has poor firmness and weather resistance during the construction process. The roadbed will be eroded by wind and sand if it is exposed to the natural environment for a long time, which will affect the service life of the expressway roadbed. For this reason, we provide a high-speed Roadbed Earthwork Reinforcement Method for Highway Engineering
