Suspension bridge large-diameter secant pile gravity type anchorage foundation enclosure structure and construction method
The invention discloses a suspension bridge large-diameter secant pile gravity type anchorage foundation enclosure structure and a construction method. The suspension bridge large-diameter secant pile gravity type anchorage foundation enclosure structure comprises a plurality of I-stage secant piles and a plurality of II-stage connecting piles, the I-stage secant piles and the II-stage connecting piles are sequentially and circularly connected and enclose to form a circular enclosure, and a plurality of dewatering wells are arranged in a foundation pit in the enclosure; and waterproof curtains are arranged at the joints of the outer walls of the I-stage secant piles and the II-stage connecting piles. According to the design, the structure is simple, the lining does not need to be constructed through a reverse construction method in the excavation process, therefore, construction procedures are reduced, the construction period is shortened, damage to the enclosure structure caused by lining construction is prevented, and the application range of the suspension bridge is widened. The invention further discloses a corresponding construction method of the suspension bridge large-diameter secant pile gravity type anchorage foundation enclosure.
本发明公开一种悬索桥大直径咬合桩重力式锚碇基础围护结构及施工方法，包括若干Ⅰ期咬合桩和若干Ⅱ期连接桩，所述Ⅰ期咬合桩和Ⅱ期连接桩依次循环连接并围蔽形成圆形的围护，所述围护内的基坑设有若干降水井，所述Ⅰ期咬合桩和Ⅱ期连接桩的外壁连接处设有止水帷幕。本设计结构简单，实现在开挖过程中无需采用逆作法施工内衬，从而减少施工工序，缩短施工工期，防止了内衬施工而引起围护结构的损坏，扩大了悬索桥的应用范围。本发明还公开了相应的一种悬索桥大直径咬合桩重力式锚碇基础围护施工方法。
