Description
Technical field
The present invention relates to a kind of bolt support technology, is specifically a kind of three hole fillet supports for the anchoring of trapezoidal roadway bolt
Disk and application method.
Background technology
After roadway excavation, roadway surrounding rock produces displacement with destroying, and high levels collection particularly occurs at the fillet of tunnel
In and cause destruction at first.For deformation controlling for rock surrounding gateways, ensure section requirement, keep adjoining rock stability, suspension roof support is as a kind of
Universal and important active support mode, be widely used underground coal mine.
Anchor rod pallet board plays key effect as a component in Bolt System in Bolt System, but
Currently used butterfly pallet and V-arrangement pallet can not all be installed in tunnel fillet, so as to can not be led to tunnel fillet
Dynamic supporting；Limited plus due to space near at the fillet of tunnel and pallet specification, following some problems can be brought：Trapezoidal lane
Road fillet is easy to stress concentration occur but is not reinforced, so as to be easier that failure by shear occurs, is caving country rock；Lane
Influence each other when the pallet of portion of side and top plate is installed at road fillet, construction is very not convenient；Top plate and portion of side at the fillet of tunnel
Pallet is not connected with each other, and supporting effect is undesirable.
To solve the above-mentioned problems, propose the present invention, to carrying out anchor pole active support at the fillet in trapezoidal tunnel, drop significantly
The low plastically deforming area of tunnel fillet, prevents occurring failure by shear at fillet, and multipurpose tray is simple in structure, has a style of one's own,
Convenient construction, avoids top plate and influence mutual during portion of side installation anchor rod pallet board installation at the fillet of tunnel, by tunnel shoulder
Top plate and the anchor rod pallet board in portion of side are connected as a single entity at angle, improve the globality of anchor rod anchored country rock body, reduce trapezoidal tunnel
The deformation failure of country rock at fillet.
