The invention provides a pebble stratum waterproof curtain construction method. The method comprises the following steps of S1, ascertaining geological conditions, investigating soil characteristics in a depth range, and determining whether a gravel pebble layer with relatively large thickness exists or not; S2, performing grooving through a grab bucket type grooving machine; S3, back-filling the groove with plain soil; and S4, performing stirring by a three-shaft stirring pile machine, and performing grouting to form a wall. According to the method, construction is conducted by multiple equipment together, respective advantages of the equipment are fully utilized, machine abrasion is reduced, construction difficulty is lowered, the construction period is effectively shortened, construction efficiency and construction quality are improved, and cost is saved.
本发明提出一种卵石地层止水帷幕施工方法，包括以下步骤：S1：探明地质情况，勘察该深度范围内土质特点，确定是否存在厚度较大的砾石卵石层；S2：抓斗式成槽机成槽施工；S3：槽内换填素土；S4：三轴搅拌桩机搅拌、注浆成墙。该方法采用了多设备并行施工，充分利用设备各自优势，减少机器磨损，降低施工难度，有效地缩减工期，提高施工效率和施工质量，节约了成本。
