水泥就地冷再生施工常見的問題:

Common problems in the construction of on-site cold recycling of cement:

1、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(jìn)行人工找平后壓路機(jī)碾壓。

1. If the local water of the mixture is large, in order to prevent the grout from boiling. It is necessary to excavate the mixture with large water content and replace it with a mixture with suitable water content (if the construction section is rolled, more cement shall be added). After backfilling, it shall be leveled manually and rolled with a roller.

2、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(jī)重新倒車作業(yè)重打，如是漏打的地方很小，則應(yīng)鋪滿冷再生轉(zhuǎn)子一樣大的地方，由再生機(jī)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)。

2. If there is a section of road that has been constructed and the phenomenon of missing or skipping is found, cement shall be paved manually in proportion in the area where the cold recycling missing is found, and the recycling machine shall back up again. If the missing area is very small, the place as large as the cold recycling rotor shall be paved, and it shall be lifted after the recycling machine buckles the knife. The principle is to avoid repeated drilling to damage the completed structure.

3、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(jī)作業(yè)的供水，用振動(dòng)壓路機(jī)迅速振動(dòng)碾壓一遍后，如混合料沾輪情況嚴(yán)重，平地機(jī)迅速找平后停止光輪壓路機(jī)碾壓，用振動(dòng)壓路機(jī)振動(dòng)碾壓2遍后即可。

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 depending on 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 smooth wheel roller shall be stopped after the grader quickly leveling, and then the vibratory roller can be used to vibrate and roll twice.
