冷再生機施工工藝之整形、碾壓注意事項

來源:http://www.szwif.com/ 日期:2023-07-07
整形
plastic
(1)混合料拌和平均后,應立刻用平地機初步整形。在直線段,平地機由兩側向路中心停止刮平;在平曲線段,平地機由內側向外側停止刮平。
(1) After the mixture is evenly mixed, it shall be preliminarily shaped with a Grader immediately. In the straight section, the Grader stops scraping from both sides to the road center; In the flat curve section, the Grader stops scraping from the inside to the outside.
(2)用輪胎壓路機立刻在初平的路段上快速碾壓一遍,以暴露潛在的不平整。
(2) Immediately use a tire roller to quickly roll over the initially flat road section to expose potential unevenness.
(3)再用平地機按本條第1款停止整形,整形前應用齒耙將輪跡低洼處表層5cm以上耙松,并按本條第2款再碾壓一遍。
(3) Then use the Grader to stop shaping according to paragraph 1 of this article. Before shaping, use the tooth harrow to loosen the surface of the low-lying part of the wheel track for more than 5cm, and roll it again according to paragraph 2 of this article.

碾壓
Rolling
(1)整形后,當混合料的含水量為佳含水量(+1%~+2%)時,應立刻用壓路機在構造層全寬內停止碾壓。直線和不設超高的平曲線段,由兩側路肩向路中心碾時,應堆疊1/2輪寬,后輪必需超越兩段的接縫處,后輪壓完路面全寬時,即為一遍。普通需碾壓4~6遍。
(1) After shaping, when the moisture content of the mixture reaches the optimal moisture content (+1%~+2%), the roller should immediately stop rolling within the full width of the construction layer. When rolling straight and flat curved sections without superelevation from the shoulders on both sides to the center of the road, they should be stacked with a width of 1/2 of the wheel width. The rear wheel must exceed the joint of the two sections. When the rear wheel has pressed the full width of the road surface, it is considered as one pass. Normally, it needs to be rolled 4-6 times.
(2)嚴禁壓路機在已完成的或正在碾壓的路段上調頭或急剎車,應保證改進土層外表不受毀壞。
(2) It is strictly prohibited for road rollers to turn around or brake sharply on completed or rolling sections, and it is necessary to ensure that the surface of the improved soil layer is not damaged.
(3)碾壓過程中,水泥改進土的外表應一直堅持潮濕,如水分蒸發過快,應及時補撒少量的水,但嚴禁灑大水碾壓。
(3) During the rolling process, the surface of cement modified soil should always be moist. If the water evaporates too quickly, a small amount of water should be sprinkled in a timely manner, but it is strictly prohibited to sprinkle large amounts of water for rolling.
(4)冷再生機租賃人員認為,經過拌和、整形的水泥改進土,宜在水泥初凝前并應在實驗肯定的延遲時間內完成碾壓,并到達請求的密實度,同時沒有明顯的輪跡。
(4) The leasing personnel of the cold recycling machine believe that the cement improved soil after mixing and shaping should be compacted before the initial setting of the cement and within the confirmed delay time in the experiment, and reach the requested compactness without obvious wheel marks.
(5)在碾壓完畢之前,用平地機再終平一次,使其縱向順適,路拱和超高契合設計請求。終平應認真停止,必需將部分高出局部刮除并掃出路外;關于部分低洼之處,不再停止找補,可留待下層施工時處置。
(5) Before the completion of rolling, use a Grader for final leveling again to make it longitudinally smooth, and the crown and superelevation meet the design requirements. The final leveling should be stopped seriously, and it is necessary to scrape off the parts that are higher than the original ones and sweep them out; Regarding some low-lying areas, repair will no longer be stopped and can be left for disposal during lower level construction.
