Description

Self-advancing hollow grouting resin anchor rod

Technical Field

The utility model relates to a tunnel geotechnical engineering anchor bolt support field specifically is a from advancing formula cavity slip casting resin stock.

Background

The anchor bolt support is characterized in that one end of an anchor bolt is anchored in a surrounding rock body, axial pre-tightening force is applied to the anchor bolt outside the rock body, and deformation separation, crushing expansion and slippage dislocation of the surrounding rock are restrained through supporting components such as a tray and the like. The anchor bolt support is used as a safe and efficient main support mode of tunnel engineering, and is popularized and applied in large area in tunnel engineering and coal mine roadway support in China.

In present tunnel engineering, often can pass through the area of poisonous and harmful gas, wherein gas is the biggest to tunnel excavation danger coefficient, though there is strict gas monitoring facility and system, nevertheless because the gas concentration of every district all is different in the tunnel, can't detect the gas concentration condition in all areas in whole tunnel, but anchor bolt support is as the extremely wide supporting mode of cover face in a tunnel, if can play the effect of supporting, and monitor the inside gas concentration in tunnel, can reduce cost by a wide margin, and all have very big help to workman's life and property safety and the smooth of engineering.

On the other hand, if conventional processes are used for bolting, the surrounding rock is required to have better structural integrity, the bolt can be drilled for installing the drill hole, and the complete drill hole structure and shape are reserved after the drill hole is drilled and the drill rod is withdrawn. However, the underground is very complex, and not only a large amount of soft rock strata exist, but also a large amount of geological structures such as folds, faults and the like exist in the stratum. Such surrounding rocks are often poor in structural integrity, forming a fractured rock mass. The hole wall is easy to collapse when the drill rod is withdrawn after the hole is drilled in the broken rock body, and particularly when the hole is influenced by mining dynamic pressure, the anchor rod is more difficult to install the drilled hole, and the construction quality and speed of anchor rod support are seriously influenced.

After the self-propelled grouting drill rod is used for grouting, the surrounding rock is broken to form a complete force transmission structure, the structural integrity can be obviously improved, and conditions are created for anchor bolt support construction. In view of the application conditions of several existing anchor rods, the anchor rods have the defects, such as full-length bonding anchor rods, and the anchor rods cannot continuously complete drilling, anchoring and grouting in one-time construction; the anchor rod can be enlarged along with the deformation of surrounding rocks and is quickly broken in high ground stress tunnels and underground engineering; the metal anchor rod is inconvenient to machine and high in cost.
