冷再生机施工期间的控制要点与问题处理
来源:https://www.sddhfjx.com/ 日期:2023-06-02
(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 optimal moisture content of the mixture is to grab a handful of the mixture with one hand, firmly grip it, and then release the hand to let it fall freely to the ground. Normally, it will immediately scatter flowers without any small lumps inside. Repeated experiments have shown that the critical moisture content between loose ground and clumping is the optimal moisture content, which is generally 1% -2% higher than the optimal moisture content value on the test sheet.
2、作业施工冷再生机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 parking the cold recycling machine during operation, it is necessary to leave the road surface that has been constructed or the cement has been paved to prevent local water leakage.
3、施工车辆停放时一定要错开第二天的段道预工作面,以防止耽误第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 the first section of the first pre working surface of the next day to prevent delaying the manual cement paving of the next day. Construction vehicles should not be parked on the completed road surface. Prevention and control of damage to new structures and impact on later watering and health preservation.
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 making the mistake of "over compaction", that is, over compaction. If the material continues to be compacted after reaching its high density, it will damage the material and instead reduce its density.
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 work of the cold regeneration machine should end between 15:00 and 16:00 every afternoon, so that subsequent construction can be completed before dark.
6、每天冷再生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,以免耽误第二天的施工进度。
6. After the construction of the cold regeneration machine is completed and the knife is washed and stopped every day, the operator should be notified to carefully check the condition of the vehicle and replace the knife head to avoid delaying the construction progress of the next day.

三、冷再生机租赁厂家再来讲讲常见问题的处理方法
3、 Let's talk about the common problem solving methods for cold regeneration machine rental manufacturers again
1、如果混合料局部水大的话,为防止翻浆压不住。需将水大的混合料挖出换成含水量适合的混合料(如是碾压完成的施工段需多掺水泥)回填后,进行人工找平后压路机碾压。
1. If there is a large amount of water in the local area of the mixture, in order to prevent it from boiling and not being compressed. The mixture with high water content needs to be excavated and replaced with a mixture with suitable water content (such as adding more cement to the compacted construction section) for backfilling, and then manually leveled and rolled by a roller.
2、如有施工完路段,发现漏条或跳打现象,由人工在冷再生漏打的地域按比例铺上水泥,再生机重新倒车作业重打,如是漏打的地方很小,则小应铺满冷再生转子一样大的地方,由再生机扣刀打一下即抬起,原则就是避免多打,破坏已完成的结构。
2. If there is a section of the road that has been constructed and any missing bars or skip marks are found, the area where the cold regeneration missed marks is manually laid with cement in proportion, and the regeneration machine is reversed to start the operation again. If the skip marks are very small, the small area should be covered with the same size as the cold regeneration rotor, and the regeneration machine should be used to lift it up after hitting it with a knife. The principle is to avoid excessive hitting and damaging the completed structure.
3、如果雨季施工水泥已铺到路上,赶上下雨,视雨水大小情况,适当减少或停止冷再生机作业的供水,用振动压路机迅速振动碾压一遍后,如混合料沾轮情况严重,平地机迅速找平后停止光轮压路机碾压,用振动压路机振动碾压2遍后即可。还有什么问题就来我们网站https://www.sddhfjx.com咨询!
3. If the construction cement has been paved on the road in rainy season, and it rains, the water supply for cold recycling machine operation shall be appropriately reduced or stopped according to the size of the rain. After the vibratory roller is used to quickly vibrate and roll once, if the mixture is seriously stained with wheels, the grader shall quickly level it, and then stop the smooth wheel roller rolling, and the vibratory roller can be used to vibrate and roll twice.
