Before paving, determine the large and small paving width and set the paver accordingly.

摊铺工作同时需要与工地其它部门紧密合作，确保不间断的供料和避免供料耗时过多。料车应尽量安排合理，避免摊铺过程中走走停停。

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. The hopper car shall be arranged reasonably to avoid walking and stopping during paving.

与搅拌站保持联系，确保按计划供料。

Keep in touch with the mixing plant to ensure that the materials are supplied as planned.

经常性检查摊铺机使用状况，及时保养维护（例如，检查油位水位，电气和液压功能是否正常等）。料车的保温苫布应在即将送料时去除，这样可以避免摊铺料温度降低。接下来，就让我们一起进入今天的--摊铺层厚度设定。由于摊铺工序受到诸多因素的影响，迄今为止还没有一个精确公式能够根据预期厚度设定熨平板仰角油缸的位置。

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.). 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. 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，当使用伸缩式熨平板时，一般遵循以厘米为单位的摊铺厚度+(50 100%)的数值为摊铺机设定的摊铺厚度。此设定应在摊铺前几米时进行再次校对。摊铺机摊铺施工图解大家都知道，熨平板只提供预压实，终的密实度应由压路机压实实现。而压路机的压实深度(W)即为摊铺厚度(H)与预期摊铺厚度(S)之间的差值，此数值也应在设定熨平板时提前进行考虑。

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. As we all know, the screed only provides pre-compaction, and the final 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.

摊铺机开始摊铺施工前的注意事项由于熨平板处于浮动模式下，只有经过一段时间的摊铺才能达到预期的摊铺厚度，因此建议将熨平板停放在垫木或者均匀撒布的材料上起步。摊铺仰角的设定为摊铺厚度(H)+ (50 100%)，可通过仰角油缸上的刻度进行设置。鱼尾板在其标准位置。另外，应在开始摊铺时及时检查摊铺层厚度，以便需要时能够及时校正仰角油缸的位置。

Precautions before the paver starts paving construction Since the screed is in floating mode, the expected paving thickness can only be achieved after a period of paving, it is recommended to park the screed on the skid or evenly distributed material to start. 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.

经过压路机压实后，必须检查预期摊铺厚度。如果与预期值不符，应及时校对使之达到预期摊铺厚度。

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.
