Method for constructing cast-in-place concrete pile at high altitude
The invention discloses a method for high-altitude construction of a cast-in-place concrete pile. The method comprises the steps that an opening is chiseled in a trestle in a foundation pit; paving two roadbed boxes on the trestle, wherein the two roadbed boxes are arranged on two opposite sides of the hole; erecting a pile machine on the two roadbed boxes; a drilling rod of the pile machine is lowered to the bottom of the foundation pit through the hole to drill to form a pile hole, during drilling construction of the pile machine, a mud box is installed at the bottom of the foundation pit, a small mud pit is arranged, a large mud pit is arranged at the top of the foundation pit, mud in the pile hole flows into the small mud pit, and the mud in the small mud pit is pumped into the mud box through a mud pump; then the slurry in the slurry box is pumped into the large slurry pool through the slurry pump, and finally the slurry in the large slurry pool is pumped to the pile machine to be recycled. Pouring a cast-in-place concrete pile in the pile hole; and blocking the hole in the trestle. The problem that a pile machine cannot enter the foundation pit for construction operation due to the limitation of a trestle, a support and other components when a cast-in-place concrete pile is additionally arranged in the foundation pit is solved.
本发明公开了一种高空施工混凝土灌注桩方法，包括于基坑内的栈桥上凿开洞口；于栈桥上铺设两块路基箱，两块路基箱设置于洞口的相对两侧；于两块路基箱上架设桩机；桩机的钻杆经由洞口下放至基坑的底部钻进形成桩孔，在桩机钻孔施工中，于基坑的底部安装泥浆箱并布设小型泥浆池，并于基坑的坑顶布设大型泥浆池，桩孔内的泥浆流入小型泥浆池内，通过泥浆泵将小型泥浆池内的泥浆抽入泥浆箱内，再通过泥浆泵将泥浆箱内的泥浆抽入大型泥浆池，最后将大型泥浆池内的泥浆泵送至桩机循环利用；于桩孔内浇筑混凝土灌注桩；封堵栈桥上的洞口。本发明解决了基坑内增设混凝土灌注桩，由于栈桥和支撑等构件限制，导致桩机无法进入基坑内部施工作业的问题。
