Station plate wall synchronous side wall construction method based on cover and excavation top-down construction
The invention discloses a station board wall synchronous side wall construction method based on cover and excavation top-down, and aims to solve the technical problem of serious water leakage in the prior art. The construction method comprises the steps that after excavation is conducted to the bottom of the small formwork, a water stop steel plate is pre-buried, and a cushion layer is poured; the top plate and the middle plate are constructed through a small formwork, and the height of the small formwork ranges from 1.5 m to 2 m; concrete pouring holes are preset in the top plate and the middle plate, and vibrating holes are preset in the side walls; after the upper side plate and the lower side plate are completed, waterproof structures are constructed among the top plate, the middle plate and the side walls for water prevention, then a large steel formwork is adopted to be matched with a sky pump or/and a ground pump for side wall concrete pouring between the plates, and vibration is conducted through the vibration holes; and after side wall concrete is poured to the vibrating hole, the side wall concrete is sealed by a template in time, and the concrete is vibrated through the pouring hole, so that the side wall joint and the concrete in the pouring hole are compact. The waterproof function of the side wall construction structure is guaranteed through combination of the water stop steel plate and grouting pouring, and the construction efficiency is greatly improved.
本申请公开了一种基于盖挖逆作的车站板墙同步侧墙施工方法，旨在解决现有技术渗漏水严重的技术问题。所述施工方法为：开挖至小模架底部后，预埋止水钢板，浇筑垫层；然后采用小模架施工顶板与中板，所述小模架高度为1.5‑2m；在所述顶板和中板上预设砼浇筑孔，并在侧墙上预设振捣孔；待上下两侧板完成后，在所述顶板、中板与侧墙之间施作防水结构进行防水，然后采用大钢模板配合使用天泵或/和地泵进行板与板之间的侧墙砼浇筑，并通过所述振捣孔进行振捣；侧墙砼浇筑至振捣孔后及时采用模板封住，并通过浇筑孔振捣混凝土，使侧墙接缝与叫浇筑孔内的混凝土密实。利用止水钢板与注浆浇筑相结合保证侧墙施工结构的防水功能，并极大地提高施工效率。
