Installation and construction method of ultra-long steel sheet pile three-section type anchor pulling and fixing device

The invention discloses an installation construction method of a super-long steel sheet pile three-section type anchor pulling fixing device, which comprises the steps of S1 soil layer leveling and pile sinking lineation, S2 pile sinking of a super-long steel sheet pile, S3 pile sinking of an anchorage pile, S4 steel guide beam installation, S5 anchorage pull rod device installation, S6 surface layer sand covering, stone covering, soil covering and the like. Anchor pulling and fixing between the super-long steel sheet pile and the anchorage pile are achieved through the three-section type anchorage pull rod device, the anchorage pull rod device can conduct pulling force without large deformation under additional stress, the overall stability is high, water tightness is good, and safety and reliability are achieved. 本发明公开了一种超长钢板桩三段式拉锚固定装置的安装施工方法，包括S1土层平整及沉桩划线，S2超长钢板桩的沉桩，S3锚碇桩的沉桩，S4钢导梁安装，S5锚碇拉杆装置安装，S6表层覆砂、覆石、覆土等步骤，工艺简单，通过三段式的锚碇拉杆装置实现超长钢板桩与锚碇桩之间的拉锚固定，在附加应力下锚碇拉杆装置即可传导拉力又不会产生较大变形，整体稳定性高，水密性好，安全可靠。
