混合料佳含水量現(xiàn)場監(jiān)測辦法,一手抓起一把混合料,用力握實,然后松手讓其自由落向地面,正常會立即摔散花,里面沒有小團料。反復(fù)試驗,介于落地松散和抱團之間的臨界含水量即佳含水量,一般比試驗單上的佳含水量數(shù)值多1%-2%。
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.
作業(yè)施工冷再生機停車時一定要離開已施工或待施工水泥已攤鋪路面,以防止漏水引起的局部水大。
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.
施工車輛停放時一定要錯開第二天的第一段第一道預(yù)工作面,以防止耽誤第二天的人工水泥攤鋪,施工車輛好不要停放在已完成施工的路面上。防治破壞新建結(jié)構(gòu)和影響后期灑水養(yǎng)生。
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.
避免犯“過壓”的錯誤,即過度壓實。若達到材料的大密實度后仍然繼續(xù)碾壓,則會破壞材料,反而降低其密實度。
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.
冷再生租賃機的施工作業(yè)應(yīng)該在每天下午15:00—16:00之間結(jié)束,以便后續(xù)施工能在天黑前結(jié)束。
The construction work of the cold regeneration rental machine should end between 15:00 and 16:00 every afternoon, so that subsequent construction can be completed before dark.
每天冷再生機結(jié)束施工進行洗刀停車后,應(yīng)通知操作手仔細(xì)檢查車況并更換刀頭,以免耽誤第二天的施工進度。
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.
冷再生租賃機常見問題有哪些處理方法
What are the common problems and solutions for cold regeneration rental machines
如果混合料局部水大的話,為防止翻漿壓不住。需將水大的混合料挖出換成含水量適合的混合料(如是碾壓完成的施工段需多摻水泥)回填后,進行人工找平后壓路機碾壓。
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.
如有施工完路段,發(fā)現(xiàn)漏條或跳打現(xiàn)象,由人工在冷再生漏打的地域按比例鋪上水泥,再生機重新倒車作業(yè)重打,如是漏打的地方很小,則小應(yīng)鋪滿冷再生轉(zhuǎn)子一樣大的地方,由冷再生租賃機扣刀打一下即抬起,原則就是避免多打,破壞已完成的結(jié)構(gòu)。
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 missed mark is very small, the small mark should be covered with a place as large as the cold regeneration rotor, and the cold regeneration leasing machine should be used to lift it with just one click of the knife. The principle is to avoid excessive marks and damage to the completed structure.
如果雨季施工水泥已鋪到路上,趕上下雨,視雨水大小情況,適當(dāng)減少或停止冷再生機作業(yè)的供水,用振動壓路機迅速振動碾壓一遍后,如混合料沾輪情況嚴(yán)重,平地機迅速找平后停止光輪壓路機碾壓,用振動壓路機振動碾壓2遍后即可。
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.
