水泥就地冷再生施工注意事項
Precautions for construction of cement local cold recycling
（一）控制要點
（1） Control points
1、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%。
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、作業(yè)施工水罐車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。
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、施工車輛停放時一定要錯開二天的一段一道預(yù)工作面，以防止耽誤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。
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“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。
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。
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、每天冷再生租賃機結(jié)束施工進行洗刀停車后，應(yīng)通知操作手仔細檢查車況并更換刀頭，以免耽誤二天的施工進度。
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.
