Side slope damping drilling method
The invention provides a side slope damping drilling method. The side slope damping drilling method comprises the following steps that a drilling machine, a soil body drill bit, a rock mass drill bitand a combined protection pipe are provided, wherein the combined protection pipe comprises an inner-layer sleeve and an outer-layer sleeve installed on the outer circumferential surface of the inner-layer sleeve in a sleeving mode, the soil body drill bit is installed on the drilling machine, and the drilling machine is started to enable the soli body drill bit to drill an upper-layer soil body of a side slope and obtain a front section hole; then, the combined protection pipe is pressed into the front section hole; and then the rock mass drill bit is installed on the drilling machine, the drilling machine is started to enable the rock mass drill bit to penetrate through the combined protection pipe, then drill into a lower-layer rock mass of the side slope, and obtain a rear section hole, and when the accumulated depth of the front section hole and the rear section hole reaches the preset hole forming depth, construction is finished. The technical scheme is adopted, various measuresare adopted to effectively prevent the phenomenon that the holes cannot be formed due to hole collapse and chipping in the drilling process, the hole forming quality is guaranteed, the construction progress is guaranteed, disturbance to the side slope soil body or rock mass is reduced, and a foundation is laid for guaranteeing stability and reliability of ground buildings.
本发明提供一种边坡减震钻孔方法，包括以下步骤：提供钻机、土体钻头、岩体钻头和组合护管，组合护管包括内层套管和套装于内层套管外周面上的外层套管，将土体钻头安装在钻机上，启动钻机使土体钻头钻通边坡上层土体并获得前段孔，然后将组合护管压入前段孔内；再将岩体钻头安装在钻机上，启动钻机使岩体钻头穿过组合护管后钻进边坡下层岩体并获得后段孔，待前段孔与后段孔累计深度达到预设成孔深度时，施工结束。采用本发明的技术方案，采取多种措施有效防止了钻孔过程中出现塌孔、掉块以致无法成孔的现象，确保了成孔质量，保障了施工进度，减少了对边坡土体或岩体的扰动，为保障地面建筑物的稳定和可靠奠定了基础。
