Soft foundation soil layer ultra-deep foundation pit excavation equipment and construction method
The invention provides soft foundation soil layer ultra-deep foundation pit excavation equipment which comprises an excavator body, the output end of the excavator body is connected with a mechanical arm, and an excavator bucket is hinged to the end of the mechanical arm; the excavator bucket comprises an arc-shaped bucket plate hinged to the mechanical arm, and a penetrating type mounting groove is formed in the side wall of the arc-shaped bucket plate. In the process of excavating a soft soil base layer, when the edge of a pile foundation is excavated, two arc-shaped extension plates are made to slide towards the two sides of a mounting groove along the mounting groove through a driving mechanism, two side bucket plates are driven to move, the distance between the two side bucket plates is adjusted, an opening of an excavator bucket is enlarged, and the pile foundation is excavated. The distance between the side bucket plate of the excavator bucket and the mechanical arm is increased, at the moment, the two movable bucket teeth move, one movable bucket tooth and the fixed bucket tooth are located on the two sides of the pile foundation correspondingly, soil on the side, away from the excavator body, of the pile foundation can be directly excavated, the position of the excavator body does not need to be adjusted, and the working efficiency is improved; and the excavation efficiency of the ultra-deep foundation pit of the soft foundation soil layer is improved.
本发明提供一种软基土层超深基坑开挖设备，包括挖掘机本体，挖掘机本体输出端连接有机械臂，机械臂端部铰接有挖斗；所述挖斗包括铰接在机械臂上的弧形斗板，弧形斗板侧壁开设有贯穿式安装槽。本发明在对软土基层挖掘过程中，当挖掘到桩基边缘处时，通过驱动机构使得两个弧形延伸板分别沿安装槽向安装槽两侧进行滑动，带动两个侧斗板进行移动，对两个侧斗板之间间距进行调节，使得挖斗的开口变大，使得挖斗的侧斗板与机械臂之间间距增加，此时，两个移动斗齿位移，使得其中一个移动斗齿与固定斗齿分别位于桩基的两侧，即可对桩基远离挖掘机本体一侧泥土直接挖掘，不需要调整挖掘机本体自身位置，提高工作效率，提高对软基土层超深基坑挖掘效率。
