Description
Technical Field
The utility model relates to an anchor rope tray technical field specifically is an anchor net cable spouts and struts suitable anchor rope tray in tunnel.
Background
In the underground roadway support of a coal mine, particularly in the roadway jointly supported by anchor net cable spraying (anchor rods, anchor cables, metal nets and guniting), because the 300 x 300mm anchor cable tray is used at present, the surface of the tray is smooth due to one-step hot rolling forming, and when the tray is matched with guniting support, slurry is not easy to adhere to the surface of the tray, so that the later-stage slurry layer is easy to adhere or fall off. After falling off, the internal support is exposed, leaked, weathered or corroded, so that the support strength is reduced, and the service life of the roadway is further reduced; the slurry layer is not firmly bonded, so that the falling risk exists, and the safety of pedestrians is threatened.
In the existing coal mine underground roadway anchor net cable-jet support, a slurry layer outer anchor cable reinforcement mode is mostly adopted, or a small tray is selected, so that the slurry layer bonding problem is solved.
The reinforcing support mode is adopted, the anchor cable is injected outside the grout layer, the effective use area of the roadway is influenced, the exposed part is influenced by the underground environment, the weathering and corrosion risks exist, the service life of the reinforcing anchor cable is easily reduced, and the service life of the roadway is further influenced; by adopting the small tray, the effective supporting area of the anchor cable can be reduced, the supporting effect is weakened, and the service life of the roadway can be influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides an anchor net cable spouts and struts anchor rope tray suitable for tunnel has solved the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the anchor cable tray suitable for the anchor net cable spraying support roadway comprises a tray, hollow holes are formed in the outer side of the tray, reinforcing ribs are arranged on the surface of the tray, and tray holes are formed in the middle of the tray.
As an optimized technical scheme of the utility model, the cross-section of strengthening rib is trapezoidal.
As an optimal technical scheme of the utility model, the limit in fretwork hole is the arc.
The utility model discloses has following useful part:
the utility model is suitable for an anchor net cable spouts supports tunnel and is suitable for anchor rope tray adopts fretwork cooperation strengthening rib setting, under the prerequisite of intensity is strutted in the assurance, changes former tray two-way bonding and for the quadriversal bonding, has promoted the adhesive force of slurry, improves the problem of tunnel service life, has reduced later stage tunnel maintenance expense.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In one embodiment, please refer to fig. 1-4, an anchor cable tray for an anchor net cable-jet supporting roadway includes a tray 1, a hollowed hole 2 is formed on an outer side of the tray 1, edges of the hollowed hole 2 are arc-shaped, so as to avoid excessive local stress, a reinforcing rib 4 is formed on a surface of the tray 1, and a tray hole 3 is formed in a middle of the tray 1. The reinforcing ribs 4 are arranged on the upper surface of the tray 1, and the cross sections of the reinforcing ribs 4 are trapezoidal, so that the reinforcing ribs 4 are better stressed.
The fully-closed form of the original anchor cable tray is changed into hollow-out arrangement so as to increase the contact area between the tray 1 and slurry and increase the adhesive force, the reinforcing ribs 4 are arranged on the surface of the tray 1 so as to guarantee the supporting strength of the tray 1, the cross sections of the reinforcing ribs 4 are arranged in a trapezoid manner, and the contact area between the reinforcing ribs 4 and the slurry is increased. The anchor cable tray 1 can adopt a hot rolling process for one time so as to guarantee the strength and deformation requirements of the tray 1.
This embodiment is at implementation in-process, and the anchor rope is beaten and is annotated the back, installation anchor rope tray 1, then the whitewashing is strutted, and the area of contact of slurry and tray 1 can greatly increased, has effectively promoted the slurry adhesion force, by original single about two-way bonding, becomes about four-way bonding from top to bottom, slurry fully wraps up tray 1, makes the slurry be difficult for droing, support intensity and service life in guarantee tunnel.
The utility model is suitable for an anchor net cable spouts supports tunnel and is suitable for anchor rope tray adopts fretwork cooperation strengthening rib 4 to set up, under the prerequisite of intensity is strutted in the assurance, changes former 1 two-way bonding of tray and for the quadriversal bonding, has promoted the adhesive force of slurry, improves the problem of tunnel service life, has reduced later stage tunnel maintenance expense.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
