壓路機(jī)運行時的碾壓原則您知道是什么嗎?為了后面使用該機(jī)器更好的進(jìn)行施工,相關(guān)運行的原則就要知道,下面濟(jì)南壓路機(jī)出租人員就來講講這個問題。
Do you know what the rolling principle is when the roller is running? In order to use the machine for better construction, we need to know the relevant operation principles. Now, the taxi staff of Jinan Road Roller will talk about this problem.
1、壓路機(jī)壓路時要從公路的邊沿壓起,壓實路面逐漸向公路中間移動。前側(cè)的軋輥應(yīng)具有一定的重疊寬度,雙輥式壓路機(jī)與單輪式壓路機(jī)的交迭寬度為250~300mm,而三輪式壓路機(jī)的交疊寬度應(yīng)為主壓輪的二分之一左右。
1. When rolling, the road roller shall lift from the edge of the road, and the compacted road surface shall gradually move towards the middle of the road. The roll at the front side shall have a certain overlap width. The overlap width of the double roll roller and the single wheel roller shall be 250~300mm, while the overlap width of the three wheel roller shall be about half of the main roller.
2、壓路機(jī)碾壓技術(shù):在工作過程中,壓路機(jī)應(yīng)該在起動前啟動,而內(nèi)燃發(fā)動機(jī)應(yīng)先達(dá)到中等速度,再轉(zhuǎn)到高速。當(dāng)坡面非常陡峭的時候,須先用小型壓路機(jī)進(jìn)行預(yù)壓,然后用重型壓路機(jī)或壓路機(jī)進(jìn)行壓實。
2. Rolling technology of road roller: in the working process, the road roller should be started before starting, and the internal combustion engine should reach the medium speed first, then turn to the high speed. When the slope is very steep, a small roller shall be used for pre compaction first, and then a heavy roller or roller shall be used for compaction.
3、在直線上進(jìn)行壓實,壓實應(yīng)遵循“由輕到重、由慢到快、由邊到中(曲線段按先內(nèi)、后外)”的原則。使用1次靜壓+3-4次震動+1次靜壓的方法,運行速度以3-6/小時為宜。
3. Compaction shall be carried out on a straight line, following the principle of "from light to heavy, from slow to fast, and from edge to middle (the curve section shall be first inside and then outside)". Use the method of one static pressure+3-4 shocks+1 static pressure, and the operating speed is 3-6 km/h.
4、將壓路機(jī)盡可能的接近攤鋪機(jī),采用先輕后重的加壓方式進(jìn)行壓路,以保證混凝土在冷卻到小溫度之前能滿足密實度的要求。在碾碎新的瀝青路面時,為了降低路面的起皺和開裂,駕駛員應(yīng)先把主動輪開到新鮮的混合料場中。保證沖擊碾壓的速度是恒定的,在熱料層上不能隨意停頓、轉(zhuǎn)彎,而且起步要慢,以減少壓痕。
4. The road roller shall be close to the paver as much as possible, and the road shall be compacted in a light to heavy way to ensure that the concrete can meet the requirements of compactness before it is cooled to a low temperature. When crushing the new asphalt pavement, in order to reduce the wrinkling and cracking of the pavement, the driver should first drive the driving wheel to the fresh mixture yard. Ensure that the speed of impact rolling is constant, do not stop or turn at will on the hot material layer, and start slowly to reduce the indentation.
此外,無論是上坡還是下坡,都應(yīng)該把壓路機(jī)的傳動輪放在后方。這樣可以保證上坡時,后輪能承受斜坡和機(jī)械本身的推動力,而前輪在地面上進(jìn)行初步壓縮,從而抵抗來自驅(qū)動輪的強(qiáng)大剪切力;下坡時,由于壓路機(jī)自身重量所帶來的沖力由主動輪的剎車所抵消,而只有前車輪碾壓后的混合料具有支撐后驅(qū)動輪的剪力。
In addition, the driving wheel of the roller should be placed behind both uphill and downhill. This can ensure that the rear wheel can withstand the driving force of the slope and the machine itself when going uphill, while the front wheel is preliminarily compressed on the ground to resist the strong shear force from the driving wheel; When going downhill, the impact brought by the roller's own weight is offset by the brake of the driving wheel, while only the mixture rolled by the front wheel has the shear force supporting the rear driving wheel.
壓路機(jī)運行時的碾壓原則就是如此內(nèi)容了,希望給您好的幫助,當(dāng)然平常要注意對機(jī)器設(shè)備的保養(yǎng)維護(hù)哦。更多相關(guān)事項就來我們網(wǎng)站http://m.guixin.net.cn咨詢吧!
