Embodiment Construction

[0024] Such as figure 1 , figure 2 Shown, a kind of composite anchoring, it comprises anchor cable body 4 and pad platform 6, backing plate 7 and anchor plate 8. Both the pad 6 and the backing plate 7 are provided with anchor cable holes 9; the top of the anchor cable body 4 passes through the anchor cable holes 9 of the pad 6 and the backing plate 7 in sequence and is connected to the anchor plate 8; the lower part of the anchor cable body 4 It is a cable structure composed of steel wires 11 distributed in layered steps, and a water-resistant cylindrical explosive 12 equipped with a detonator 10 is sandwiched between the outer layer and the inner layer of each step.

[0025] Wherein: the lengths of the steel wires 11 of each layer in the anchor cable body 4 are different, and the outer layer is short, the inner layer is long, and the central axis is the longest.

[0026] There is a grouting hole 13 on the backing plate 7 .

[0027] The anchoring method of this composite a...

Abstract

The invention relates to composite anchor which comprises an anchor cable body as well as a cushion table, a cushion plate and an anchor plate; and an anchor cable hole is formed in each of the cushion table and the cushion plate. the top end of the anchor cable body sequentially passes through the anchor cable hole of the cushion table and the anchor cable hole of the cushion plate to connect with the anchor plate; the lower part of the anchor cable body is equipped with a cable structure which consists of steel wires in layered step distribution; and waterproof cylindrical explosives with detonators are sandwiched between the outer layer of each step and the inner layer of each step. Meanwhile, the invention further discloses an anchoring method for the composite anchorage. The composite anchorage is simple in structure, is convenient to construct, is low in cost, can provide great anchorage force, improves the anchorage effect, and can remarkably quicken project progress.

Description

technical field [0001] The invention relates to rock soil reinforcement and support technology, in particular to a composite anchor and an anchor method. 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 technical problem to be solved by the presen...
