在開始攤鋪工作前,關(guān)于攤鋪層厚度設(shè)定的準(zhǔn)備工作。
Preparations for paving layer thickness setting before paving work.
開始攤鋪工作前,應(yīng)確定大和小攤鋪寬度,并對(duì)攤鋪機(jī)做相應(yīng)設(shè)定。
Before paving, determine the large and small paving width and set the paver accordingly.
攤鋪工作同時(shí)需要與工地其它部門緊密合作,確保不間斷的供料和避免供料耗時(shí)過多。
At the same time, the paving work needs to work closely with other departments on the site to ensure uninterrupted supply of materials and avoid excessive supply time.
料車應(yīng)盡量安排合理,避免攤鋪過程中走走停停。
The hopper car shall be arranged reasonably to avoid walking and stopping during paving.
與攪拌站保持聯(lián)系,確保按計(jì)劃供料。
Keep in touch with the mixing plant to ensure that the materials are supplied as planned.
經(jīng)常性檢查攤鋪機(jī)使用狀況,及時(shí)保養(yǎng)維護(hù)(例如,檢查油位水位,電氣和液壓功能是否正常等)。
Regularly check the use condition of the paver and timely maintain it (for example, check whether the oil level and water level, electrical and hydraulic functions are normal, etc.).
料車的保溫苫布應(yīng)在即將送料時(shí)去除,這樣可以避免攤鋪料溫度降低。
The thermal insulation tarpaulin of the hopper car shall be removed when the material is about to be delivered, so as to avoid the temperature reduction of the paving material.
接下來,就讓我們一起進(jìn)入今天的重點(diǎn)——攤鋪層厚度設(shè)定。由于攤鋪工序受到諸多因素的影響,迄今為止還沒有一個(gè)精確公式能夠根據(jù)預(yù)期厚度設(shè)定熨平板仰角油缸的位置。
Next, let's enter today's focus - paving layer thickness setting. Because the paving process is affected by many factors, so far there is no accurate formula to set the position of the screed elevation cylinder according to the expected thickness.
因此,當(dāng)使用伸縮式熨平板時(shí),一般遵循以厘米為單位的攤鋪厚度+(50 至 100%)的數(shù)值為攤鋪機(jī)設(shè)定的攤鋪厚度。此設(shè)定應(yīng)在攤鋪前幾米時(shí)進(jìn)行再次校對(duì)。
Therefore, when using the telescopic screed, generally follow the paving thickness in cm+(50 to 100%) value as the paving thickness set by the paver. This setting should be checked again a few meters before paving.
大家都知道,熨平板只提供預(yù)壓實(shí),的密實(shí)度應(yīng)由壓路機(jī)壓實(shí)實(shí)現(xiàn)。而壓路機(jī)的壓實(shí)深度(W)即為攤鋪厚度(H)與預(yù)期攤鋪厚度(S)之間的差值,此數(shù)值也應(yīng)在設(shè)定熨平板時(shí)提前進(jìn)行考
As we all know, the screed only provides pre-compaction, and the compactness should be achieved by the roller compaction. The compaction depth (W) of the roller is the difference between the paving thickness (H) and the expected paving thickness (S). This value should also be considered in advance when setting the screed
由于熨平板處于浮動(dòng)模式下,只有經(jīng)過一段時(shí)間的攤鋪才能達(dá)到預(yù)期的攤鋪厚度,因此建議將熨平板停放在墊木或者均勻撒布的材料上起步。
Since the screed is in floating mode, the expected paving thickness can only be achieved after a period of paving, so it is recommended to park the screed on the skid or evenly distributed material to start.
攤鋪仰角的設(shè)定為攤鋪厚度(H)+ (50 至100%),可通過仰角油缸上的刻度進(jìn)行設(shè)置。魚尾板在其標(biāo)準(zhǔn)位置。另外,應(yīng)在開始攤鋪時(shí)及時(shí)檢查攤鋪層厚度,以便需要時(shí)能夠及時(shí)校正仰角油缸的位置。
The setting of paving elevation is paving thickness (H)+(50 to 100%), which can be set by the scale on the elevation cylinder. The fishplate is in its standard position. In addition, the thickness of the paving layer should be checked in time when paving is started, so that the position of the elevation cylinder can be corrected in time when necessary.
經(jīng)過壓路機(jī)壓實(shí)后,必須檢查預(yù)期攤鋪厚度。如果與預(yù)期值不符,應(yīng)及時(shí)校對(duì)使之達(dá)到預(yù)期攤鋪厚度。
After compaction by the roller, the expected paving thickness must be checked. If it is inconsistent with the expected value, it shall be checked in time to make it reach the expected paving thickness.
