無論是壓路機(jī)的任何操作控制,必須保證操作臺(tái)和座椅固定牢靠的前提下進(jìn)行,尤其是可移動(dòng)式操作臺(tái)和座椅。下面濟(jì)南壓路機(jī)出租人員就闡述一下壓路機(jī)的操作控制對(duì)路面壓實(shí)效果的影響。
Regardless of any operation control of the roller, it is necessary to ensure that the operating platform and seat are firmly fixed, especially the movable operating platform and seat. Below, Jinan roller rental personnel will elaborate on the impact of roller operation control on the compaction effect of the road surface.
壓路機(jī)的操作控制主要有:行走控制、轉(zhuǎn)向控制、振動(dòng)控制、噴水量控制,以及一些碾壓操作技巧上的控制。
The operation control of road rollers mainly includes: walking control, steering control, vibration control, water spray control, and some control techniques for rolling operations.
壓路機(jī)的行走控制
Walking control of road rollers
要保證控制手柄控操靈活且有手感,不緊不松。起步時(shí)要輕緩,不可起步過急否則驅(qū)動(dòng)輪會(huì)形成向后推移的作用力,使松鋪瀝青層造成推移現(xiàn)象,影響壓實(shí)效果。
Ensure that the control handle is flexible and tactile, not tight or loose. When starting, it should be gentle and not too fast, otherwise the driving wheel will form a backward pushing force, causing the loose asphalt layer to push and affect the compaction effect.
運(yùn)行時(shí)要保證勻速行駛,按照施工要求,初壓一般控制在1.5m/h~2Km/h,復(fù)壓控制在4m/h~5Km/h,終壓控制在2m/h~3Km/h。壓實(shí)過程中的瞬間停車不可過急,否則與急起步相同會(huì)造成松鋪瀝青層的推移現(xiàn)象。
During operation, it is necessary to ensure uniform driving speed. According to construction requirements, the initial pressure is generally controlled at 1.5m/h-2Km/h, the re pressure is controlled at 4m/h-5Km/h, and the final pressure is controlled at 2m/h-3Km/h. The instantaneous stop during the compaction process should not be too rapid, otherwise it will cause the same phenomenon as the rapid start, which will cause the loose asphalt layer to move.
壓路機(jī)的轉(zhuǎn)向控制
Steering control of roller
壓路機(jī)在碾壓轉(zhuǎn)向變幅時(shí),必須輕緩流暢,轉(zhuǎn)彎半徑不可過小,速度不可過快。否則,由于轉(zhuǎn)向時(shí)的慣性和離心力會(huì)造成瀝青混合料的擠壓推移,影響路面的壓實(shí)效果。
When rolling and turning, the roller must be gentle and smooth, with a turning radius that is not too small and a speed that is not too fast. Otherwise, due to the inertia and centrifugal force during turning, the asphalt mixture will be squeezed and pushed, affecting the compaction effect of the road surface.
壓路機(jī)的振動(dòng)控制
Vibration control of road rollers
操作過程中,我們主要要控制的是壓路機(jī)振動(dòng)的開啟和關(guān)閉時(shí)刻。壓路機(jī)的振動(dòng)只有在進(jìn)行復(fù)壓(主壓)階段才會(huì)開啟,而且必須在啟動(dòng)后開振、提前關(guān)振,切不可原地開振碾壓。
During the operation process, we mainly need to control the opening and closing times of the roller vibration. The vibration of the roller can only be started during the re compaction (main compaction) stage, and it must be started and closed in advance after starting, and cannot be rolled in place.
隨著技術(shù)進(jìn)步,許多壓路機(jī)設(shè)置了自動(dòng)開啟和關(guān)閉振動(dòng)的功能,通過一“手動(dòng)/自動(dòng)”轉(zhuǎn)換開關(guān)完成,當(dāng)速度達(dá)到某一數(shù)值時(shí)自動(dòng)開啟,當(dāng)速度低于某一數(shù)值時(shí)又自動(dòng)關(guān)閉。
With the advancement of technology, many road rollers have been equipped with automatic opening and closing vibration functions, which are completed through a "manual/automatic" conversion switch. When the speed reaches a certain value, it will automatically start and then close again when the speed is below a certain value.
壓路機(jī)鋼輪的噴水量控制
Water spray control of roller steel wheels
經(jīng)常檢查前后兩水箱的儲(chǔ)水量,及時(shí)添加。前后鋼輪上的兩排噴嘴以及濾網(wǎng)濾芯要經(jīng)常檢查清洗,保持清潔。噴灑水量的大小有操作臺(tái)上的6個(gè)控制檔位進(jìn)行選擇,一般情況選擇在4檔位置。噴灑水量過大過小都不利于壓實(shí)。過大,加快了瀝青混合料的冷卻,縮短了碾壓時(shí)間。過小,瀝青混合料由于溫度較高容易粘輪。
Regularly check the water storage capacity of the front and rear water tanks and add them in a timely manner. The two rows of nozzles and filter elements on the front and rear steel wheels should be regularly inspected and cleaned to maintain cleanliness. The amount of water sprayed can be selected from six control gears on the control console, usually in the fourth gear position. Spraying too much or too little water is not conducive to compaction. If it is too large, it accelerates the cooling of the asphalt mixture and shortens the rolling time. If it is too small, the asphalt mixture is prone to sticking to the wheel due to high temperature.
壓路機(jī)的壓實(shí)技巧
Compaction techniques of road rollers
我們按照施工技術(shù)員的施工方案、壓實(shí)工藝進(jìn)行碾壓,如:碾壓速度、壓實(shí)溫度和碾壓遍數(shù)等。其次,我們必須保證各壓路機(jī)的同步碾壓,做好碾壓的一致性。并遵守“緊跟穩(wěn)壓、由外向內(nèi)、由低往高、先慢后快”的碾壓原則。壓路機(jī)的相鄰碾壓帶應(yīng)重疊1/3~1/2輪寬。
We roll according to the construction technician's construction plan and compaction process, such as compaction speed, compaction temperature, and number of compaction passes. Secondly, we must ensure synchronous rolling of each roller and ensure consistency in rolling. And adhere to the rolling principle of "closely following the stable pressure, from the outside to the inside, from the low to the high, and from slow to fast". The adjacent rolling strips of the roller should overlap by 1/3-1/2 wheel width.
壓路機(jī)的碾壓技巧很多,必須在碾壓施工中不斷的去摸索,精益求精,才能達(dá)到更佳的壓實(shí)效果。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://m.guixin.net.cn進(jìn)行咨詢了解吧!
