Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] see figure 1 , the present invention provides a technical solution: a construction method for leveling and leveling with a grader in roadbed construction, the specific operations are as follows:
[0020] S1. Transport the earthwork to the roadbed and pave it;
[0021] S2. In the double-lane highway with a cross-section every ten meters, four trapezoidal mounds with a loose paving coefficient are made on the lower layer of the roadbed, arranged along th...

The invention discloses a land leveler leveling and fine leveling construction method in roadbed construction, and relates to the technical field of roadbed construction. The land leveler leveling andfine leveling construction method in roadbed construction comprises the following specific operation steps: S1, earthwork is transported to a roadbed and paved on the roadbed; and S2, four trapezoidal mounds with loose paving coefficients are made on the lower layer of the roadbed every ten-point one-meter section of two lanes of the highway and are arranged along the left shoulder, two sides ofthe center and the right shoulder of the road, and then cylindrical scales (firm and graduated) are arranged on the sides of the trapezoidal mounds in a lofting manner. The land leveler is used for shoveling and scraping in the direction perpendicular to the center line of the roadbed, the defect that the elevation of a longitudinal scraping seam is prone to generating wavy lines due to repeated adjustment of a scraping plate of a traditional longitudinal scraping face is overcome, the leveling speed of a single roadbed basically reaches 99%, and the requirement of a high-quality roadbed is met.
Description
technical field [0001] The invention relates to the technical field of roadbed construction, in particular to a construction method for shoveling and fine-leveling by a grader in roadbed construction. Background technique [0002] In the prior art, the main construction technology of highway engineering subgrade construction is: soil filling-primary leveling-rough compaction-finish leveling-compacting to the required degree of compaction. The construction technology and mechanical parameters of the subgrade directly determine the forming quality of the subgrade. The quality inspection items of the subgrade mainly include: degree of compaction, flat speed, transverse slope, center deviation, etc. Flatness is especially important in the process of subgrade construction, which directly affects the layer thickness control of each filling layer. If the flatness is not well controlled, there will be places where the compaction is not in place, or spring phenomena will occur. The ...
