Abstract
The utility model relates to a combined type hollow grouting anchor rod. According to an anchor rod used for underground tunnel construction in China and an existing hollow grouting anchor rod, outer surfaces are provided with threads, hollow inner surfaces do not provided with threads, wall thickness is not uniform, shearing strength is poor, seriflux outlets are only formed in drill bits, and grouting is not full. The combined type hollow grouting anchor rod comprises a hollow grouting anchor rod body A (1). The hollow grouting anchor rod body A is connected with a hollow grouting anchor rod body B through a combined type connecting sleeve (2), an anchor head (4) is installed at the end of the hollow grouting anchor rod body A, a seriflux check plug (5) is installed on the hollow grouting anchor rod body B, the seriflux check plug is connected with an arched base plate (6) which is connected with a spherical nut (7), and a seriflux plug (8) is installed at the end of the hollow grouting anchor rod body B. The combined type hollow grouting anchor rod is used for slope protection.
Description
Technical field:
The utility model relates to a kind of combined type hollow grouting anchor.
Background technology:
The domestic anchor pole of using at construction of underground tunnel, generally by anchor pole, the backing plate of the drill bit of anchor pole front end and anchor pole afterbody and clamp nut constitute, and its working procedure is to punch with special-purpose auger earlier, extracts the drilling rod grouting behind shaft or drift lining out, inserts anchor pole at last country rock is carried out anchoring.Existing hollow grouting anchor, its external surface generally has screw thread, and hollow interior surface does not have screw thread, and wall unevenness is even, and shear strength is poor, only has grout outlet on the drill bit, and slip casting is not full.
Summary of the invention:
The purpose of this utility model provides a kind of combined type hollow grouting anchor.
Above-mentioned purpose realizes by following technical scheme:
A kind of combined type hollow grouting anchor, its composition comprises: hollow grouting anchor body A, described hollow grouting anchor body A is connected with hollow grouting anchor body B by the combined type adapter sleeve, the end of described hollow grouting anchor body A is equipped with anchor head, on the described hollow grouting anchor body B stop grouting plug is installed, described stop grouting plug is connected with the arch backing plate, and described arch backing plate is connected with spherical nut, and described hollow grouting anchor body B end is equipped with stifled slurry plug.
Described combined type hollow grouting anchor, the external surface of described hollow grouting anchor body A, described hollow grouting anchor body B has screw thread.
Beneficial effect:
The utility model is selected the high-quality seamless steel pipe for use, hollow grouting anchor body A, described hollow grouting anchor body B are processed into surfaces externally and internally and are full thread, and wall thickness uniformity, make anchor pole shear strength unanimity, thereby prolong anchor pole application life, hollow bolt unites two into one the function of anchor pole and Grouting Pipe.It is Grouting Pipe during slip casting, and need not after slip casting finishes it is extracted namely becomes an anchor pole.Hollow design makes anchor pole realize the function of Grouting Pipe, and the mortar that has caused when having avoided traditional construction technology Grouting Pipe to extract runs off.Slip casting is full, and can realize slip casing by pressure, has improved workmanship.The property placed in the middle of hollow grouting anchor body A, described hollow grouting anchor body B is fine, and mortar can have been avoided the danger of corrosion with anchor pole total length parcel, reaches the purpose of long-term supporting.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment:
Embodiment 1:
A kind of combined type hollow grouting anchor, its composition comprises: hollow grouting anchor body A, piece number: 1, described hollow grouting anchor body A is by combined type adapter sleeve 2 and hollow grouting anchor body B, piece number: 3 connect, the end of described hollow grouting anchor body A is equipped with anchor head 4, on the described hollow grouting anchor body B stop grouting plug 5 is installed, described stop grouting plug is connected with arch backing plate 6, described arch backing plate is connected with spherical nut 7, and described hollow grouting anchor body B end is equipped with stifled slurry plug 8.
Embodiment 2:
According to embodiment 1 described combined type hollow grouting anchor, the external surface of described hollow grouting anchor body A, described hollow grouting anchor body B has screw thread.
Claims (2)
