Protective wall of manual hole digging pile and construction method of protective wall of manual hole digging pile
The invention provides a retaining wall of a manual hole digging pile and a construction method of the retaining wall of the manual hole digging pile, and relates to the technical field of manual hole digging pile construction.The retaining wall of the manual hole digging pile is characterized in that in the process that the retaining wall is installed in a pile hole, a fore shaft ring (10) is arranged at the top of the pile hole, and the outer diameter of a standard knot (20) can be matched with the inner diameter of the fore shaft ring (10); in the pile hole excavation process, each standard knot (20) is installed by being arranged in the locking ring (10) in a sleeved mode, the previous standard knot (20) is automatically connected with the next standard knot (20) in a clamped mode under the action of vertical force, the standard knots (20) integrally move downwards under the action of the vertical force, the lowermost standard knot (20) is made to make contact with the hole bottom of the pile hole all the time, and therefore the pile hole is excavated. It is guaranteed that the lap joint distance between the top of the uppermost standard knot (20) and the bottom of the locking ring (10) is not smaller than the preset lap joint amount, automatic clamping alignment is good, and the hole forming perpendicularity of a pile hole can be guaranteed.
本发明提供了一种人工挖孔桩的护壁及人工挖孔桩的护壁的施工方法，涉及人工挖孔桩施工技术领域，该人工挖孔桩的护壁包括：在护壁安装在桩孔的过程中，锁口圈(10)设于桩孔的顶部，标准节(20)的外径与锁口圈(10)的内径能够相匹配，在开挖桩孔的过程中，每一节标准节(20)均通过套设于锁口圈(10)内进行安装，且使得上一节标准节(20)在竖向力的作用下与下一节标准节(20)自动卡接在一起，标准节(20)在竖向力作用下整体向下移动，使得最下面一节标准节(20)始终接触于桩孔的孔底，保证最上面一节标准节(20)的顶部与锁口圈(10)的底部的搭接距离不小于预设搭接量，自动卡接对位好，能够保证桩孔的成孔垂直度。
