The invention discloses lateral soil pouring equipment for a height limiting space in a foundation pit and a foundation pit earth excavation method. The equipment comprises a pressure-bearing pile, a bearing frame, a belt conveyor and a locking structure; the outer diameter of the pressure-bearing pile is gradually increased from top to bottom; the bearing frame is arranged opposite to the pressure-bearing pile and is provided with a cross beam; the belt conveyor is provided with an input end and an output end which are opposite to each other, the input end is arranged above the pressure-bearing pile, the output end is arranged below the cross beam, a first lug plate is formed at the input end, a vertical through hole aligned to the pressure-bearing pile is formed in the first lug plate, a second lug plate is formed at the output end, a length-adjustable sling is connected to a position between the second lug plate and the cross beam; and the locking structure is installed in the vertical through hole, an inserting opening with the adjustable caliber is formed in the locking structure, and the pressure-bearing pile is movably sleeved with the inserting opening of the locking structure. The equipment solves the problems that under the condition of ultra-low clearance height, a large excavator cannot be adopted for deep foundation pit earth excavation, but only a small excavation machine can be adopted for deep foundation pit earth excavation, and the excavation efficiency is seriously affected.
本发明公开了一种基坑内的限高空间侧向倒土设备及基坑土方开挖方法,该设备包括:承压桩,其外径自上而下逐渐增大;与承压桩相对设置的支承架,设有横梁;带式输送机,具有相对的一输入端和一输出端,输入端设置于承压桩的上方,输出端设置于横梁的下方,输入端形成有第一耳板,第一耳板开设有对准于承压桩的竖向贯孔,输出端形成有第二耳板,第二耳板与横梁之间连接有长度可调的吊索;以及锁合结构,安装于竖向贯孔内,锁合结构内形成有口径可调的插口,锁合结构的插口可活动地套设于承压桩。本发明解决了在超低净空高度的情况下,深基坑土方开挖无法采用大型挖机,而只能采用小型开挖机械严重影响开挖效率的问题。
