Retard-bonded prestressed cast-in-situ underground diaphragm wall and construction method thereof
The invention discloses a retard-bonded prestressed cast-in-place underground diaphragm wall and a construction method thereof, and aims to provide a retard-bonded prestressed cast-in-place underground diaphragm wall which can ensure the rigidity and crack resistance of the underground diaphragm wall under the condition of reducing the use amount of reinforcing steel bars, reduce the construction cost of engineering, reduce the hoisting construction difficulty of a reinforcement cage and improve the construction efficiency. The invention discloses a retard-bonded prestressed cast-in-place underground diaphragm wall convenient for field hoisting operation of a reinforcement cage and a construction method thereof. The retard-bonded prestressed cast-in-place underground diaphragm wall comprises a reinforcement cage embedded in the underground diaphragm wall; the base is fixed on the reinforcement cage; the retard-bonded prestressed tendons are sequentially distributed in the length direction of the underground diaphragm wall, each retard-bonded prestressed tendon comprises a prestressed steel strand and a sleeve arranged outside the prestressed steel strand in a sleeving mode, and the bottom of each prestressed steel strand is anchored to the base through a lower anchorage device. And the top of the prestressed steel strand is anchored on the wall top of the underground diaphragm wall through an upper anchorage device.
本发明公开了一种缓粘结预应力现浇地下连续墙及其施工方法，旨在提供一种能够在减少钢筋用量的情况下，保证地下连续墙的刚度和抗裂性能，实现降低工程造价，减小钢筋笼吊装施工难度，便于钢筋笼现场吊装作业的缓粘结预应力现浇地下连续墙及其施工方法。缓粘结预应力现浇地下连续墙，包括：钢筋笼，钢筋笼埋设在地下连续墙内；基座，基座固定在钢筋笼上；若干缓粘结预应力筋，各缓粘结预应力筋沿地下连续墙的长度方向依次分布，缓粘结预应力筋包括预应力钢绞线及套设在预应力钢绞线外的套管，预应力钢绞线的底部通过下锚具锚固在基座上，预应力钢绞线的顶部通过上锚具锚固在地下连续墙的墙顶。
