Problems solved by technology
[0003] In the existing technical solutions, the angle ruler is generally used to locate the drilling hole position. The practical angle ruler can only determine the approximate orientation, and it is not convenient to fix and locate the drill hole. The actual use efficiency is low. Single anchor cable, anchor rod drilling positioning The effect is low, the positioning accuracy is not high, and the construction quality is difficult to guarantee

The invention discloses a drilling orientation controller for NPR anchor cable construction, and specifically relates to the technical field of anchor cable drilling positioning. An installation convex ring is provided, and a first threaded hole is arranged inside the installation convex ring, and a vertical support rod is connected to the internal thread of the first threaded hole, and a horizontal adjustment rod is slidably connected to the inside of the slideway, and the adjustment block The other side is provided with a second threaded hole. The invention adjusts the vertical support rod left and right to closely adhere to the surrounding rock, and directly locates the drilling position. The coordinates of the adjustment block are the positioning of the drilling position, so as to realize the rapid and accurate positioning of the drilling rod on the anchor cable drilling equipment, and meet the needs of different rock formations with inclination angles. The anchor cable drilling construction standardizes the precise positioning of the anchor cable position, effectively solves the problem of irregular anchor cable construction and the penetration angle does not meet the requirements, improves the safety factor of drilling, and is simple and convenient to set up, easy to operate, and improves construction efficiency. .
Description
technical field [0001] The invention relates to the technical field of anchor cable drilling positioning, and more specifically, the invention relates to an NPR anchor cable construction drilling orientation controller. Background technique [0002] Anchor cable means that when the main cable is anchored in the side hole in the suspension bridge, the main cable should be divided into many strands of steel bundles and anchored in the anchor spindle respectively. These steel bundles are called anchor cables. The anchor cable is fixed on the slope surface through the outer end, and the other end is anchored in the stable rock mass within the sliding surface, passing through the prestressed steel strand on the sliding surface of the slope, directly generating anti-sliding resistance on the sliding surface, increasing the anti-sliding Frictional resistance keeps the structural surface in a compact state to improve the integrity of the rock mass of the slope, thereby fundamentally...
