Abstract

The invention relates to an expanded head composite anchor device. The expanded head composite anchor device comprises an anchor cable body, a cushion platform, a base plate and an anchor plate. The cushion platform and the base plate are both provided with anchor cable holes. The top end of the anchor cable body sequentially penetrates through the anchor cable holes of the cushion platform and the base plate and is connected with the anchor plate together. A cable structure which is composed of steel wires distributed in a layered step mode is arranged on the lower portion of the anchor cable body. A water-resistant cylindrical explosive filled with a detonator is clamped between the outer layer and the inner layer of each step. An anchoring section of the anchor cable body is anchored into a cone-frustum-shaped grouting body. The cone-frustum-shaped grouting body is formed by grouting of cone-frustum-shaped anchor holes. Meanwhile, the invention discloses an anchoring method of the expanded head composite anchor device. According to the expanded head composite anchor device and the anchoring method thereof, the structure is simple, construction is convenient, cost is low, huge anchored force can be provided, the anchoring effect is improved, and the progress of work can be accelerated obviously.

Description

technical field [0001] The invention relates to rock-soil mass reinforcement and support technology, in particular to a composite anchoring of an enlarged head and an anchoring method thereof. Background technique [0002] Over the past few decades, landslide prevention methods and technologies have been developed rapidly, especially the anchoring technology, which tightly interlocks the strata through anchor cables buried in the strata, and has been used in mines, water conservancy, hydropower, highways, etc. , railway, municipal, urban construction, geology, military and other fields have been widely used, and play a key role in the construction of major national economic projects. However, the existing anchoring technology has limited anchoring force, unsatisfactory reinforcement effect, high cost, difficult construction, complex process and other problems, which seriously restrict its further popularization and application. Contents of the invention [0003] The techn...
