Hollow anchor bolt manufacturers discuss common problems in the entire process of anchor rod construction, and some difficulties encountered in the entire process of anchor rod construction.

　　Xinben recommends to talk about common problems in the whole process of bolt construction:

　　1. The anchor rod bursts. The high support form on the south side of the construction project is horizontally separated from the adjacent construction site by 24-26m. During the anchor hole opening, two anchor rods are blasted to the adjacent construction site to form an outflow of the slurry body. The selection method is grouting for the adjacent construction site to repair leakage. Choose the angle adjustment method for the anchor rod or the explosion position, increase the inclination of the anchor rod to prevent explosion, and pay attention to the construction in the same position as the second anchor rod. Hollow grouting anchor

　　2. The anchor rod repels. At the second anchor rod construction site, the opening collided with the pre-stressed anchor cable on the adjacent construction site. Because the adjacent construction site anchor rods are separated by 1.2m, the construction project is 1.5m, and it is inevitable that it will be stumbling. Select the method to make up the leakage of the hole, adjust the position and restart the opening construction. Before construction, you can choose to view the construction drawings overlaid with the stumbling, and adjust the position of the stumbling. Hollow bolt manufacturers

　　3. The anchor rod root pressing experiment is only carried out in the southwest. Before the construction of the anchor rod, the anchor rod root pressure test was carried out on the southwest side. The ultimate pull-out bearing capacity of the related anchor rod and the anchor rod axial tensile strength index value define the inclusions. The tensile force exceeds the axial tensile strength index value during the field experiment. , I feel that it meets the requirements.

　　The specific experiment recognized the ultimate pull-out bearing capacity of the bolt. Dividing the ultimate load-bearing capacity of the bolt by the index value 2, is the characteristic value of the bolt pull-out bearing capacity matrix. When the anchor rod was constructed in other directions, the reference value of the anchor rod tensile strength could not meet the requirements of the overall planning. The overall planning company adjusted the tensile strength value and the approved value, and reconfirmed the plan.
