Description

A assembled direction cap for stock

Technical Field

The utility model belongs to the technical field of the stock, specifically speaking is an assembled direction cap that is used for stock suitable for a large amount of materials.

Background

The anchor rod is widely applied to projects such as foundation pits, side slopes, water conservancy projects, tunnels and the like due to good anchoring performance of the anchor rod. The length of the anchor rod is generally dozens of meters in short and fifty-six meters in long according to the soft and hard conditions of the stratum and the bearing capacity requirement of the engineering design, and is even longer. In engineering, the anchor rod generally applies prestress, so that the steel strand is basically adopted as a rib body. Because the steel strand wires are softer, when putting down to the stock drilling in-process, easily the downwarping pierces the drilling bottom soil body in, not only leads to producing the soil sediment in the drilling, is difficult to transfer to the design degree of depth moreover. In actual engineering, most of the anchor rods are forcibly jacked to the designed depth by a drilling machine, so that the construction efficiency is extremely low, and certain potential safety hazards are caused to the engineering. In large-scale engineering, occasionally, a guide device with a certain function is arranged at the bottom of the anchor rod rib body, but simple devices such as a cone and the like are processed by temporarily welding sheet iron. Despite a certain positive effect compared to not mounting the guide, the following is clearly established: (1) the components are temporarily processed, so that the manufacturing error is large and the manufacturing efficiency is low; (2) the rib body and the rib body are mainly connected and fixed in a welding way, so that the installation is very troublesome; (3) the manufacturing and installation efficiency is low, and the manufacturing cost is very high.
