Pile opening protection method for cast-in-place pile hole
The invention discloses a pile opening protection method for a cast-in-place pile hole, which comprises the following steps: a, a pile opening protection device is manufactured, wherein the pile opening protection device comprises an upper positioning cylinder and a lower supporting cylinder, and the upper positioning cylinder sleeves the upper end of the lower supporting cylinder; b, the lower supporting cylinder of the supporting device manufactured in the step a is arranged in the pile hole, and the upper end of the lower supporting cylinder protrudes out of the ground; c, the upper positioning cylinder is overturned outwards to be attached to the ground, and then the upper positioning cylinder is fixed to the ground through a fixing device; and d, the lower supporting cylinder and the hole wall of the pile hole are pressed and fixed through a plurality of fixing devices. According to the supporting device, the design of the upper positioning cylinder and the lower supporting cylinder is adopted, the lower supporting cylinder is arranged in the pile hole and is fixedly supported, the upper positioning cylinder supports the pile opening in the top end of the pile hole, and therefore the upper end hole wall and the lower end hole wall of the pile hole can be effectively supported through the upper positioning cylinder and the lower supporting cylinder to prevent the pile opening from collapsing.
本发明公开了一种灌注桩桩孔的桩口防护方法，包括如下步骤：a、制作桩口防护装置，其包括上定位筒和下支护筒，上定位筒套设于下支撑筒的上端；b、将步骤a中制作的支撑装置的下支撑筒装设于桩孔内，且其上端凸出于地面；c、将上定位筒向外翻转至与地面贴合，再通过固定装置固定在地面上；d、通过多个固定装置将下支撑筒与桩孔孔壁压紧固定。本发明的支撑装置采用上定位筒和下支撑筒的设计，将下支撑筒装设于桩孔内并固定支护，上定位筒于桩孔顶端桩口支护，进而可有效通过上定位筒和下支撑筒对桩孔的上端和下端孔壁进行支护防止桩口出现坍孔。
