Roadbed filling construction method

Abstract

The invention relates to a roadbed filling construction method. The roadbed filling construction method comprises the following steps that S1, base treatment is performed, specifically, an original ground is cleaned, leveled and compacted; S2, filling and compacting are performed; S21, a dumper unloads soil according to the soil piling distance calculated according to the vehicle capacity; S22, a bulldozer is used for paving and primary leveling, then a land leveler is used for leveling in cooperation with manual work, and finally the land leveler is used for final leveling; the land leveler comprises a rack, a scraper and wheels, the wheels comprise front wheels and rear wheels, and the scraper is located between the front wheels and the rear wheels; a plurality of sliding rods are fixedly arranged on the machine frame and arranged in a staggered mode in the horizontal direction, one end of each sliding rod is fixedly connected with the machine frame, the other end of each sliding rod extends downwards, the scraper is in sliding connection with the sliding rods in the length direction of the sliding rods, and a plurality of supporting wheels used for supporting the scraper are arranged on the lower portion of the scraper. The supporting wheels are located on the side, away from the soil scraping side, of the scraper, and the walking track of each supporting wheel is located within the scraping range of the scraper.

Description

technical field [0001] The present application relates to the field of road construction technology, in particular to a roadbed filling construction method. Background technique [0002] The roadbed is the foundation of the road surface, which is excavated or filled and compacted on the original ground; the roadbed is divided into filled roadbed, excavated roadbed and half-filled and half-dug roadbed according to the cross-sectional form; the top surface of the roadbed is higher than the original ground The filled embankment is called embankment, which is a common form of road cross-section in road construction of transportation projects. [0003] Subgrade filling is usually divided into: preparation stage, construction stage, and renovation stage; four sections: filling, leveling, rolling, and inspection; eight processes: construction preparation, base treatment, layered filling, paving leveling, watering or drying, and rolling Organize the construction of the construction...

AI Technical Summary

Problems solved by technology

[0004] Filling paving is leveled using a bulldozer for initial leveling, then using a grader to level manually, and then using a grader for final leveling. There is no obvious local unevenness on the control layer; However, when the grader is working, because the surface of the roadbed is inevitably uneven, it is inevitable that the grader will bump during driving, which will affect the leveling work on the surface of the roadbed.
