The invention discloses a foundation trench backfilling construction method for protecting a basement exterior wall waterproof layer, and relates to the technical field of basement exterior wall foundation trench backfilling construction. Two layers of plastic cloth are laid between a coiled material waterproof layer and a waterproof protective layer polystyrene board of the basement outer wall, the first layer of plastic cloth is flatly pasted outside the coiled material waterproof layer of the basement outer wall, and the second layer of plastic cloth is provided with wrinkles and is wrapped and covered between the first layer of plastic cloth and an extruded polystyrene board; in the process of backfilling, rolling and tamping the foundation pit, backfilling soil sinks to drive the polystyrene board to move downwards, due to the fact that friction force between the plastic cloth is small, and the second-layer plastic cloth reserves expansion amount wrinkles, when the polystyrene board moves downwards, relative movement between the polystyrene board and the second-layer plastic cloth is small, and mainly, the second-layer plastic cloth and the first-layer plastic cloth slide relatively, and the expansion amount wrinkles are reduced. The reserved folds are stretched, friction on the surface of the coiled material waterproof layer is avoided, the resistance reducing and lubricating effects are achieved, the coiled material waterproof layer is effectively prevented from being torn, and the effect of preventing leakage of the basement outer wall is achieved.
本发明公开了一种用于保护地下室外墙防水层的基槽回填施工方法，涉及地下室外墙基槽回填施工技术领域。本发明通过在地下室外墙的卷材防水层与防水保护层聚苯板之间铺设两层塑料布，第一层塑料布平整粘贴在地下室外墙的卷材防水层外，第二层塑料布留有褶皱和起包敷盖在第一层塑料布和挤塑聚苯板之间；在进行基坑回填碾压夯实过程中回填土下沉带动聚苯板下移，因塑料布间摩擦力较小，且第二层塑料布预留伸缩量褶皱，因此聚苯板下移时，聚苯板与第二层塑料布相对移动较小，主要是第二层塑料布与第一层塑料布产生相对滑动，拉伸预留褶皱，避免卷材防水层表面发生摩擦，起到了减阻润滑作用，有效防止卷材防水层撕裂，达到防止地下室外墙渗漏的效果。
