Land leveler leveling and fine leveling construction method in roadbed construction
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.
本发明公开了一种路基施工中平地机铲平精平施工方法，涉及路基施工技术领域。该路基施工中平地机铲平精平施工方法，具体操作如下：S1、将土方运至路基处，摊铺其上；S2、在公路双车道每十米一断面，在路基的下层上做带有松铺系数的梯形土堆四个，沿着路基左路肩、路中心两侧、右路肓布置，然后在梯形土堆边侧放样设圆柱形标尺(坚固且有刻度)。该路基施工中平地机铲平精平施工方法，通过使用平地机沿着垂直路基中心线的方向进行铲刮，克服了传统纵面刮面的重复调整刮板，容易产生纵向刮缝处标高产生波浪线的缺点，使单幅路基平速度基本达到99％，达到了优质路基的要求。
