  冷再生机施工水稳施工常见问题
  Common problems in water stability construction of cold regenerator1.水泥平稳砂砾石农村基层施工时,务必选用流水线作业法,使各工艺流程密不可分对接。非常是要尽可能减少从搅拌到进行碾压中间的延迟时间。
  1. During the construction of cement stabilized sand gravel rural base, the production line operation method must be selected to make the process flow inseparable. It is very important to minimize the delay time between mixing and rolling.
  2.应做水泥平稳层的延迟时间对其抗压强度危害的实验,以明确适合的延迟时间。
  2. It is necessary to test the damage of delay time of cement stabilized layer on its compressive strength, so as to determine the suitable delay time.
  3.施工期的日低温度应在5℃之上。
  3. The daily low temperature in the construction period should be above 5 ℃.
  4.多雨季节施工水泥平稳层,应需注意气候问题,勿使水泥和混合料遭淋雨。降水时要终止施工,但已铺筑的水泥混合料应尽早碾压密实度。
  4. During the construction of cement stable layer in rainy season, attention should be paid to the climate problem, so as to avoid the cement and mixture from getting wet. The construction shall be terminated when dewatering, but the paved cement mixture shall be compacted as soon as possible.
  5.水泥平稳固层施工时,调料务必准确;撒水、搅拌应匀称。
  5. During the construction of stable cement layer, the seasoning must be accurate; the water spraying and mixing should be even.

  6.严控农村基层的厚度和标高,其路拱边坡坡率应与整体面层一致。
  6. The thickness and elevation of rural base should be strictly controlled, and the slope rate of road arch should be consistent with the overall surface course.
  7.应在混合料处在或略大好水分含量(气侯酷热干躁时,农村基层混合料可大1%~2%)时开展碾压,直至做到≥98%密实度(超重型击实规范),七天抗拉强度≥4MPa。
  7. Rolling should be carried out when the mixture is in or slightly higher moisture content (when the weather is hot and dry, the rural base course mixture can be 1% - 2%) until the compactness is ≥ 98% (super heavy compaction specification) and the seven day tensile strength is ≥ 4MPa.
  8.应用18t之上三轮压路机和超重型小型压路机及胶轮压路机碾压。用18~32t小型压路机碾压时,各层的夯实厚度不应超20厘米。夯实厚度超出所述要求时,应层次摊铺,各层的少夯实厚度为10厘米,下一层宜稍厚。应选用先轻形、后超重型振动压路机碾压。
  8. The above 18t three wheel roller, super heavy small roller and rubber tyred roller shall be used for rolling. When rolling with 18-32t small roller, the tamping thickness of each layer shall not exceed 20cm. When the tamping thickness exceeds the requirements mentioned above, it should be paved in layers. The less compacted thickness of each layer is 10cm, and the next layer should be slightly thicker. The light type vibratory roller shall be selected first and then the super heavy vibratory roller shall be used for rolling.
  9.禁止用层析减压法开展地面找平;
  9. It is forbidden to use chromatography decompression method to carry out ground leveling;10.务必保证潮湿,不使平稳层表层干躁,都不应忽干忽湿。
  10. Be sure to ensure that the surface of the stable layer is not dry or wet.
  11.水泥平稳农村基层未铺透层或整体面层时,除施工车子可慢速度(不超过30km/h)行驶外,严禁一切机动性机动车行驶。
  11. When the cement is stable and the rural base is not paved with prime coat or overall surface course, all mobile vehicles are strictly prohibited except that the construction vehicle can drive at a slow speed (no more than 30km / h).
  12.分双层冷再生机施工时,在摊铺顶层前,应在下一层墙顶先撒层析水泥或水泥水泥净浆。
  12. During the construction of double-layer cold regenerator, the chromatographic cement or cement paste should be sprayed on the top of the next layer of wall before paving the top layer.
