Construction method for ultra-deep and ultra-thick underground diaphragm wall in complex stratum
The invention discloses a complex stratum ultra-deep and ultra-thick underground diaphragm wall construction method which comprises the following construction steps: S4, grooving construction: selecting proper grooving equipment and grooving process according to a soil layer structure, ensuring grooving of an underground diaphragm wall, and reinforcing a groove wall at the same time. The device can adapt to grooving of different stratums, the grooving construction difficulty is reduced, grooving stability is good, the application range is wider, single holes are dug at intervals, partition walls are dug out, excavation is finer, deviation is corrected at any time, the excavation effect is better, sediment is dug out, follow-up construction is convenient and fast, the waterproof effect of joints is improved by wrapping grout stop iron sheets and backfilling clay and gravel, and the construction efficiency is improved. And through double-machine lifting, the herringbone truss and the diagonal draw bar are additionally arranged, so that the reinforcement cage is more stable and not prone to deformation, and the construction effect of the whole underground diaphragm wall is improved.
本发明公开了一种复杂地层超深超厚地下连续墙施工方法，包括如下施工步骤：S4、成槽施工，根据土层结构选择合适的成槽设备和成槽工艺，确保地下连续墙成槽，同时进行槽壁加固，本发明根据地层的结构情况，选择合适的成槽方式，能够适应不同地层成槽，降低成槽施工的难度，成槽稳定性好，适用范围更广，间隔挖出单孔，在挖去隔墙，开挖更加精细，随时纠偏，使挖掘的效果更好，且对沉渣进行挖除，后续施工便捷，通过包裹止浆铁皮，回填黏土和碎石，提升接头处防水效果，保证接头质量，通过双机抬吊，增设人字形桁架和斜拉杆，使钢筋笼更加稳定，不易变形，从而提升整个地下连续墙施工效果。
