塑料检查井回填乃需注意这些事项

1.塑料检查井回填，应该在排水管线验收合格后进行，这样比较有利于回填，而且塑料检查井回填应该与管道沟槽的回填同时进行。
1. The backfilling of plastic inspection wells should be carried out after the acceptance of drainage pipelines is qualified, which is more conducive to backfilling, and the backfilling of plastic inspection wells should be carried out simultaneously with the backfilling of pipeline grooves.
2.塑料检查井回填前，最好用砂土袋、钢钎、或木棍等支撑着井座、井筒，以保持其固定，并且要及时排除基坑、沟槽内积水。
2. Before backfilling the plastic inspection wells, it is better to support the wellbore and wellbore with sand bags, steel brazing, or wooden sticks to keep them fixed, and to eliminate the water accumulation in the foundation pit and trench in time.
3.回填过程中，一般在管底基础面至管顶以上0.5m范围内的沟槽，回填材料可用碎石屑、中粗沙、或者开挖出的良质土进行回填。
3. In the backfilling process, the grooves in the range of 0.5m from the bottom of the pipe to the top of the pipe can be backfilled with debris, medium-coarse sand or excavated fine soil.
4.回填过程中，回填土一定不能采用淤泥、垃圾、或者夹带石块、硬块土进行回填。
4. Mud, garbage, or rock or hard soil must not be used for backfilling in the process of backfilling.
5.在回填过程中看，如果遇冻土深度大于等于1.0m时，在冰冻层范围内，应在井筒周围不少于100mm范围内回填中粗砂。
5. In the backfilling process, if the depth of frozen soil is greater than or equal to 1.0 m, in the frozen zone, the medium-coarse sand should be backfilled in the range of not less than 100 mm around the wellbore.
6.回填时，最好采用人工回填，尽量避免机械回填，因为机械回填，很容易造成塑料检查井井筒位移和倾斜。
6. When backfilling, it is better to use manual backfilling to avoid mechanical backfilling, because mechanical backfilling can easily cause displacement and inclination of plastic inspection wellbore.
