The invention discloses a method for trench backfilling of a plastic pipe. The method comprises the following steps that stone chips are adopted to be mixed with cement of 3% for backfilling, throughthe comparison with a test section, the compaction effect obtained is consistent with the effect of medium coarse sand backfilling, the requirements of design specifications can be met, the price is low, and the price is lower than the price of medium coarse sand adopted for trench backfilling in original design by more than at least 1/3; and from the perspective of a source of goods, the source of goods is sufficient and not restricted by the national environmental protection, waste recycling can be achieved, the whole process is simple in operation, complex processes and processes do not exist, and the construction progress and efficiency are improved.
本发明公开了一种塑料管道沟槽回填的方法，采用石屑掺3%水泥回填，经过试验段对比，取得的压实效果与中粗砂回填的效果一致，能够满足设计规范要求，价格便宜，比原设计沟槽回填采用的中粗砂价格至少便宜1/3以上，从货源的角度上考虑的话，货源充足，不受国家环保的制约，可废物重新利用，整个过程操作简单，没有复杂的工序、流程，提高施工进度与效率。
