Abstract

The invention relates to a fabricated guiding cap for an anchor rod. The fabricated guiding cap comprises an anchor rod body, a plug body sleeving the anchor rod body, a limiting body, a locking ring,and a guiding cap body clamped on the plug body, wherein the limiting body and the locking ring are used for fixing the plug body. According to the technical scheme, the fabricated plug body is adopted as a carrier, the plug body can be quickly fixed through the limiting body and the locking ring, then mounting can be completed by directly inserting the guiding cap body into the plug body, fabricated construction is convenient and quick, and the efficiency is very high; and a guiding ball is arranged at the tip of the guiding cap body, thus lowering and advancing in a drill hole are very easy, the guiding cap is simple in structure, and standardized mass production is easy.

Description

technical field [0001] The invention relates to an assembled guide cap for a bolt. Background technique [0002] Anchor rods are widely used in foundation pits, slopes, water conservancy, tunnels and other projects due to their good anchoring performance. The length of the anchor rod is based on the soft and hard conditions of the ground and the requirements of the engineering design bearing capacity. Generally, the short is tens of meters, and the length is as long as fifty or sixty meters, or even longer. In engineering, anchor rods are generally prestressed, so steel strands are basically used as tendons. Because the steel strand is relatively soft, it is easy to bend down and penetrate into the soil at the bottom of the borehole when it is lowered to the bolt drilling process, which not only leads to the generation of soil slag in the borehole, but also makes it difficult to lower it to the designed depth. Most of the actual projects use drilling rigs to forcibly jack ...
