不同壓路機在瀝青路面的應(yīng)用
來源:http://guixin.net.cn/ 日期:2023-05-22
一般在現(xiàn)場,我們?yōu)榱藟簩崟r瀝青混合料要一直保持較高的溫度,目的是為了保證壓實后達到密度的要求。常規(guī)上分類,壓路機主要有三種:鋼輪壓路機、膠輪壓路機和振動式鋼輪壓路機。而目前后面的兩種壓路機在施工中運用的比較多一些。
Generally, on site, we maintain a high temperature of the asphalt mixture during compaction to ensure that it meets the density requirements after compaction. Traditionally, there are three main types of rollers: steel wheeled rollers, rubber wheeled rollers, and vibrating steel wheeled rollers. At present, the latter two types of rollers are more commonly used in construction.
濟南壓路機出租人員提醒您,壓路機的主要目的有兩個:一是為了達到規(guī)定的密度要求;二是壓出整平的路面。而壓實總共包括初壓,復(fù)壓和終壓三種形式。
Jinan roller rental personnel remind you that the main purposes of rollers are twofold: firstly, to meet the specified density requirements; The second is to press out the leveled road surface. And compaction includes three forms: initial compaction, re compaction, and final compaction.
為了去除壓路機的痕跡,是路面保持平整,不能忽略的一步,并且是采用鋼輪壓路機。當(dāng)然,要是初壓可以滿足密度要求,就不需要復(fù)壓了,不過實際在現(xiàn)場,絕大部分情況還是保持著這三步。
In order to remove the traces of the roller, it is a step that cannot be ignored to maintain a smooth road surface, and a steel wheeled roller is used. Of course, if the initial compaction can meet the density requirements, there is no need for re compaction, but in reality, in most cases, these three steps are still maintained on site.
初壓一般用鋼輪壓路機,但會出現(xiàn)推移現(xiàn)象,即滾筒前側(cè)的混合料受壓力進行橫向移動,在壓實后有可能產(chǎn)生裂縫。
Steel wheel rollers are generally used for initial compaction, but there may be displacement, where the mixture on the front side of the drum moves laterally under pressure, which may cause cracks after compaction.
也有用膠輪進行初壓的,但因為初壓時溫度較高,混合料容易粘附在輪胎上,而且留下的痕跡不容易去除,所以膠輪進行復(fù)壓的機會比較多。
Rubber wheels are also used for initial pressure, but due to the high temperature during initial pressure, the mixture is easy to adhere to the tire and the traces left are not easy to remove, so there are more opportunities for rubber wheels to be re pressed.
此外要了解一些注意事項,比如:
In addition, it is important to understand some precautions, such as:
在進行路面作業(yè)時,壓路機前后輪的刮板,應(yīng)保持平整良好。碾輪灑水機刮泥人員應(yīng)與操作手密切配合,必須跟在碾壓輪行走的后方,要注意壓路機轉(zhuǎn)向。
When carrying out road surface operations, the scrapers on the front and rear wheels of the roller should be kept flat and in good condition. The scraping personnel of the roller sprinkler should closely cooperate with the operator and must follow behind the roller when walking. Attention should be paid to the turning direction of the roller.
在改變行駛方向、減速或停駛前應(yīng)先停止振動。起振和停振必須在壓路機行走時進行;在堅硬路面行走時候嚴禁振動。碾壓松軟路基。
Stop the vibration before changing the direction of travel, slowing down, or stopping. Starting and stopping vibration must be carried out while the roller is running; Vibration is strictly prohibited when walking on hard roads. Rolling the soft roadbed.
應(yīng)先在不振動的情況下碾壓1-2遍,然后再振動碾壓。換向離合器、起振離合器和制動器的調(diào)整,必須在主離合器脫開后進行,不得在急轉(zhuǎn)彎時用快速檔;嚴禁在尚未起振情況下調(diào)節(jié)振動頻率。
Rolling should be carried out 1-2 times without vibration, followed by vibration rolling. The adjustment of the reversing clutch, starting clutch, and brake must be carried out after the main clutch is disengaged, and fast gear cannot be used during sharp turns; It is strictly prohibited to adjust the vibration frequency before the vibration has started.
壓路機操作人員必須充分考慮到機械的視線死角,嚴厲禁止存在盲目現(xiàn)象和僥幸心理駕駛機械。還有什么不懂得地方隨時來咨詢我們http://guixin.net.cn!
Roller operators must fully consider the blind corners of the machine's line of sight, and strictly prohibit driving the machine with blind or lucky mentality. If there is anything else you don't understand, feel free to consult us at any time http://guixin.net.cn !
