Kilometer level bedrock mark building construction method for controlling hole inclination
The invention discloses a kilometer level bedrock mark building construction method for controlling hole inclination. A series of new technologies such as inverted vertical hole drilling, mark post vertical control, slurry wall protection and vacuum mark fixing are adopted. The method mainly comprises the following steps that A, a site in an engineering area is leveled; b, drilling rig equipment is vertically installed, stability debugging is conducted, and mud pumping is conducted; c, the large-aperture drilling tool slightly presses, slowly rotates and conducts inverted vertical drilling, and hole inclination is monitored in time; d, adopting a vacuum standard fixing technology and novel wall protection slurry; e, the small-aperture drilling tool drills holes at variable drilling pressure and variable drilling speed; f, mounting a steel annular tray at the bottom of the drill hole; g, mounting the marker post, correcting the hole depth and controlling the hole inclination; and H, main and auxiliary headers are installed, protective exterior decoration is constructed, and relative settlement of the bedrock mark, the wall protection pipe and the protection room is observed through a differential pressure type static leveling instrument. Kilometer level bedrock marks are rare at home and abroad, discussion is carried out on site leveling, building construction, hole deviation control, level gauge installation and the like, and precious experience can be provided for follow-up construction.
本发明公开了一种控制孔斜的千米级水准基岩标建标施工方法，采用了倒垂孔钻进、标杆垂直控制、泥浆液护壁和真空固标等一系列新技术。主要包括以下步骤：A、工程区域内场地平整；B、钻架设备垂直安装、稳定性调试及泥浆泵送；C、大孔径钻具轻压慢转倒垂钻进并及时监测孔斜；D、采用真空固标技术和新型护壁泥浆液；E、小孔径钻具变钻压变钻速钻孔；F、钻孔底部钢质环装托盘安装；G、标杆安装、孔深校正及孔斜控制；H、主副标头安装，保护型外饰建设，利用压差式静力水准仪观测基岩标、护壁管及保护房相对沉降。千米级水准基岩标在国内外均为罕见，针对其场地平整、建造施工、孔斜控制及水准仪安装等进行讨论，可为后续施工提供宝贵经验。
