水泥就地冷再生施工注意事项

水泥就地冷再生施工注意事项
Precautions for construction of cement local cold recycling
(一)控制要点
(1) Control points
1、混合料佳含水量现场监测办法,一手抓起一把混合料,用力握实,然后松手让其自由落向地面,正常会立即摔散花,里面没有小团料。反复试验,介于落地松散和抱团之间的临界含水量即佳含水量,一般比试验单上的佳含水量数值多1%-2%。
1. The on-site monitoring method for the moisture content of mixtures is as follows: grasp a handful of mixtures with one hand, firmly hold them, and then let them fall freely to the ground. Normally, flowers will be scattered immediately, and there is no small mass inside. Through repeated tests, the critical water content between the ground loose and the agglomerated is the optimal water content, which is generally 1%-2% more than the optimal water content on the test sheet.
2、作业施工水罐车停车时一定要离开已施工或待施工水泥已摊铺路面,以防止漏水引起的局部水大。
2. When the construction water tanker stops, it must leave the paved road surface of the cement that has been constructed or to be constructed, so as to prevent large local water caused by water leakage.
3、施工车辆停放时一定要错开二天的一段一道预工作面,以防止耽误二天的人工水泥摊铺,施工车辆好不要停放在已完成施工的路面上。防治破坏新建结构和影响后期洒水养生。
3. When parking construction vehicles, it is necessary to stagger a section of a pre working face for two days to prevent delaying the artificial cement paving for two days. Construction vehicles should not be parked on the road surface that has been completed. Prevent and destroy the new structure and affect the later watering and curing.
4、避免犯“过压”的错误,即过度压实。若达到材料的大密实度后仍然继续碾压,则会破坏材料,反而降低其密实度。
4. Avoid the mistake of "overpressure", i.e. over compaction. If the rolling is continued after reaching the high compactness of the material, the material will be damaged, but its compactness will be reduced.
5、冷再生机的施工作业应该在每天下午15:00—16:00之间结束,以便后续施工能在天黑前结束。
5. The construction of the cold regenerator shall be completed between 15:00 and 16:00 every afternoon so that the subsequent construction can be completed before dark.
6、每天冷再生租赁机结束施工进行洗刀停车后,应通知操作手仔细检查车况并更换刀头,以免耽误二天的施工进度。
6. After the construction of the cold regeneration rental machine is completed every day and the tool is washed and stopped, the operator shall be notified to carefully check the vehicle condition and replace the tool head to avoid delaying the construction progress of the next day.
