Problems solved by technology
[0003] During the construction process of drilling the slope surface of the foundation pit, due to the steep slope, it is difficult for the construction personnel to perform accurate construction. The position is shifted during the drilling process, and the vibration of the drilling machine causes the drilling accuracy to be low
[0004] To this end, a guide device for horizontal drilling on ultra-high and steep slopes and a method for high-precision horizontal drilling are provided to solve the problem of positioning and accuracy of horizontal drilling on slopes of foundation pits

The invention relates to the technical field of horizontal drilling on a foundation pit slope, in particular to a guide device for horizontal drilling on a super-high steep slope and a method for high-precision horizontal drilling, including a steep foundation pit slope, and a pile foundation column is vertically inserted into the steep foundation pit slope, The upper end of the pile foundation column close to the pile foundation column is fixed by the upper connecting rod, the lower end of the other side of the pile foundation column is slidably installed with a tilting frame, the pile foundation column is vertically slidably installed with a guide device, and the upper connecting rod is provided with a motor The driven double-headed support with a pair of upper and lower symmetrical take-up rollers has the beneficial effects of: by setting the laser and the receiver to achieve precise level adjustment, and at the same time by setting the cooperation of the motor-driven cam and the support screw, so as to achieve The position of the height-adjusted guide device and the drilling device is fixed, thereby providing stable horizontal feed drilling and improving the accuracy and stability of drilling.
Description
technical field [0001] The invention relates to the technical field of horizontal drilling on foundation pit slopes, in particular to a guiding device for horizontal drilling on ultra-high steep slopes and a method for high-precision horizontal drilling. Background technique [0002] With the construction of high-rise buildings, the higher the number of high-rise layers, the deeper the foundation pit needs to be excavated during the construction process. In order to improve the protection of the foundation pit, it is usually necessary to drill horizontally on the slope surface of the foundation pit, and connect an external protective frame. , thereby preventing collapse. [0003] During the construction process of drilling the slope surface of the foundation pit, due to the steep slope, it is difficult for the construction personnel to carry out accurate construction. When the existing automatic drilling device is installed in the air, it is difficult to fix the position and...
