Description
Technical field
The utility model relates to a kind of Combined hollow grouted anchor bar.
Background technology
Anchor pole refers to and gos deep into ground inside and the elongated rod body controlling ground distortion.Anchor pole is as the tensional element going deep into stratum, and one end is connected with engineering structure, and the other end gos deep in stratum, and whole anchor pole is divided into free segment and anchoring section, and free segment refers to and the pulling force at anchor pole head place is reached anchoring body region, and its function is to anchor pole Shi Hanzhang; Anchoring section refers to that the region that presstressed reinforcing steel and soil layer bond by cement slurry, its function are increased at the bonding rubbing action of anchoring body and soil layer, increases the pressure-bearing effect of anchoring body, the pulling force of free segment is reached soil body depths.
Hollow grouting anchor is mainly used in the medium good country rock of geological conditions and carries out system supporting.At hard rock, rock stratum horizontal bedding, joint fissure open folder mud or underground water grows occasion, forms preliminary bracing rapidly, deformation controlling for rock surrounding gateways, ensure adjoining rock stability, then slip casting permanent anchorage by the steel shell anchor pole that rises.Punching to the design anchor pole degree of depth with hammer drill, steel anchor head is loaded onto anchor bar body, inserts in hole, after installing stop grouting plug, backing plate, nut, the reversion anchor pole shell anchor head spreading that makes to rise catches hole wall, then carries out slip casting.The anchor bar body of hollow bolt adopts hollow design, and body of rod mesopore is as creeping into high-pressure blast aquaporin and slip casting passage, and compared with the solid body of rod, hollow lever design can obtain better rigidity and shear strength.
Easily there are some problems in hollow grouting anchor traditional at present in construction, the length of such as anchor pole is inadequate, the not full not even slip casting of slip casting, these data complete hidden rear very difficult detection in construction, defect can not be remedied by Timeliness coverage, makes focus on secondary lining by the stress of the preliminary bracing System Take such as anchor pole, causes tunnel operation namely to occur Large Area Cracking soon, be out of shape, leak, not only increase later stage operation cost, keep in repair also very difficult.And due to the working environment very severe of anchor pole, be often subject to the impact of the corrosion and close region mining exploitation etc. of the underground water being rich in various chemical composition, cause corrosion of anchor bolt even to rupture.
Utility model content
The purpose of this utility model is to solve the problem, and provides a kind of novel Combined hollow grouted anchor bar.
Combined hollow grouted anchor bar described in the utility model comprises: the hollow bolt body of rod, the screw-thread steel body of rod and branch sleeve, the external surface of this hollow bolt body of rod and the screw-thread steel body of rod is provided with the external screw thread of uniform pitch; This hollow bolt body of rod and the screw-thread steel body of rod link together by this branch sleeve; The end, one end of this screw-thread steel body of rod is provided with anchor head, the end, one end of this hollow bolt body of rod is provided with stop grouting plug, backing plate and nut, wherein backing plate is arranged between stop grouting plug and nut, the right lateral surface close contact of this stop grouting plug and described backing plate, the left-hand face close contact of this nut and described backing plate, the central part of this hollow bolt body of rod forms the Grouting Pipe of hollow, and this Grouting Pipe is connected with slurry filling machine by filling adaptor; This branch sleeve is provided with pulp passage; This branch sleeve is also provided with stack.
The described screw-thread steel body of rod is solid construction.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
Combined hollow grouted anchor bar described in the utility model inserts the Anchor Agent putting into boring by combined type lever front end screw-thread steel shank portion, realize quick anchoring, by hollow bolt slip casting, make bolt grouting full solid.Combine that to form anchor rod body overall because the hollow bolt body of rod to be connected with solid anchor rod body through special linkage section, and pulp passage is just on linkage section, the usefulness of material can be made to be not fully exerted, have larger implementary value and economic results in society.Be mainly used in the country rock supporting forever that geological conditions is weak good, degaussing supporting and other temporary linings, construction costs is low, economical rationality, by combination construction, strengthens the effect of supporting.
Accompanying drawing explanation
