Pile foundation construction equipment adjacent to existing tunnel and construction method of pile foundation construction equipment
The invention relates to the field of constructional engineering, and discloses pile foundation construction equipment adjacent to an existing tunnel and a construction method of the pile foundation construction equipment adjacent to the existing tunnel. Comprising a movable rotary excavating drilling mechanism used for drilling a pile hole, a splicing type pile casing inserted into the pile hole, a drilling bottom detection mechanism detachably connected to the bottom end of the splicing type pile casing and a rotating mechanism used for rotating the splicing type pile casing. Large stones appearing in the pile hole drilling process can be detected in real time through the drill hole bottom detection mechanism, the situation that a pile casing is directly inserted into the ground under strong pressure and collides with the large stones to be damaged can be effectively reduced, and the drill hole bottom detection mechanism can be clamped on the large stones in the contact process; and the large stone is extruded to the outside of the drilling hole bottom detection mechanism through tangential force generated by rotary motion, so that the drilling efficiency is efficiently improved.
本发明涉及建筑工程领域，公开了一种紧邻既有隧道的桩基施工设备及其施工方法，其中，一种紧邻既有隧道的桩基施工设备，包括用于钻设桩孔的移动式旋挖钻孔机构、插设于桩孔内的拼接式护筒、可拆卸式连接在拼接式护筒底端的钻孔底部探测机构以及用于旋转拼接式护筒的旋转机构；本发明可通过钻孔底部探测机构进行实时探测桩孔钻进过程中出现的大型石块，可有效的降低护筒在强压下直插地下与大型石块的碰撞损伤，且钻孔底部探测机构可在接触过程中卡设在大型石块上，并通过旋转运动产生切向力来将大型石块挤压至钻孔底部探测机构外部，从而高效的提高钻进效率。
