  PVC盘管回填需要做一份好工作的安装完成后,所以的工作看似简单,实际上是非常熟练,如果安装不好,很容易创建水等问题,对产品质量的影响在未来,所以我们需要回填认真做自己的工作,混凝土回填为了什么?
  PVC coil backfilling needs to do a good job after the installation, so the work seems simple, but in fact it is very skilled. If the installation is not good, it is easy to create water and other problems, which will affect the product quality in the future, so we need to do our own work carefully. What is the purpose of concrete backfilling?
  1. 隐蔽工程验收合格后,应立即回填至管顶上方一管径高度。
  1. After the concealed work is accepted, it shall be backfilled immediately to a pipe diameter height above the pipe top.
  2. 从管道底部底部到管道顶部0.7m处进行人工回填,严禁使用机械推土机。
  2. Manual backfilling shall be carried out from the bottom of the pipeline to 0.7m from the top of the pipeline. Mechanical bulldozer is strictly prohibited.
  3.缠绕管顶部0.7m以上部位回填时,可同时从管轴两侧机械回填,夯实或滚压。
  3. When backfilling at the position 0.7m above the top of the winding pipe, mechanical backfilling, compaction or rolling can be carried out from both sides of the pipe shaft at the same time.
  4. 回填前将沟槽内的水沥干。不得回填淤泥、有机土或冻土。回填土不得含有边角坚硬的石块、砖块等大型物体。
  4. Drain the water in the trench before backfilling. No silt, organic soil or frozen soil shall be backfilled. The backfill shall not contain hard stones, bricks and other large objects.

  5. 回填应分层对称进行,每层回填高度不得超过0.2m,以保证绕线管无位移及检查井。
  5. Backfilling shall be carried out symmetrically in layers, and the height of each layer shall not exceed 0.2m, so as to ensure that there is no displacement of winding pipe and inspection well.
  回填材料及回填要求:
  Backfill materials and requirements:
  a、从管底到管顶0.4m范围内的沟道回填材料,可采用粒径小于40mm的砾石、中粗黄沙、粉煤灰或易夯实开挖的好土。
  a. For the trench backfill material within 0.4m from the pipe bottom to the pipe top, gravel with particle size less than 40mm, medium coarse yellow sand, fly ash or good soil easy to be compacted and excavated can be used.
  B,管道,坐落在巷道铺设施工道路曲折的管道或PVC管后软土地层和地势低洼的沼泽,该地区地下水位高,在粗砂槽回填应使用管底部腋角充满了密集的地方,再用粗砂或石屑分层回填管屋顶0.4米以上,可以良好的回填土。
  B. The pipeline is located in the soft soil layer and low-lying swamp behind the zigzag construction road or PVC pipe laid in the roadway. The underground water level in this area is high. In the coarse sand tank backfilling, the axil angle at the bottom of the pipe shall be used to fill the dense place, and then the coarse sand or stone chips shall be used to backfill the pipe roof 0.4m above in layers, which can be a good backfill.
  PVC回填的盘管,安装在变相的巩固和维护,确保产品在以后的不受外部因素的影响,导致设备损坏,从而影响生活,施工过程是不公平的,中等的,前面的每一步准备好,稍后将与人力和物质资源分配,解决这个问题的修理和维护,所以回填工作必须做得很好。
  PVC backfill coil is installed in the consolidation and maintenance of disguised phase, to ensure that the product will not be affected by external factors in the future, resulting in equipment damage, thus affecting life. The construction process is unfair, medium. Every step in front is ready, and later will be allocated with human and material resources to solve the problem of repair and maintenance, so the backfill work must be done well.
