Description
Technical field
The present invention relates to a kind of self-filled type total length increases to stop and oozes joint control antiknock and rush anchor pole.
Background technology
Bolt anchorage is a conventional engineering of geotechnical engineering field, and broken rock or caving ground have been played to good reinforce stabilization effect.
At present, common bolt often uses plain bar, indented bars or Ribbed Bar as anchor bar body, and common bolt pallet has cement pallet, wood composite pallet and steel plate pallet, and it is little that common bolt is reinforced rear anchor bar body increasing resistance, and stressed concentrated at anchor pole and pallet position, easily destroy.
Reinforcement with prestressed anchor can improve consolidation effect, mainly contains end bolt and grouting reinforcement and cartridge bag anchoring, because end slip casting anchoring need to be injected chemical grout to termination point of anchor rod, have the problems such as cost rising, complex procedures and contaminated environment, and it is little to apply prestressing force; Cartridge bag anchoring is to utilize dry powdered cement mortar and the special permeable paper bag of powder accelerator mixture to wrap up in, and through the direct anchoring of water soaking, its construction is simple, but can not guarantee that anchor pole is positioned at center, applies prestressing force also very little.
Summary of the invention
The invention provides one applies large, the free from environmental pollution and simple self-filled type total length of constructing of prestressing force and increases to stop and ooze joint control antiknock and rush anchor pole.
Self-filled type total length of the present invention increases to stop oozes joint control antiknock and rushes anchor pole and comprise:
Anchor bar body, is provided with hollow injected hole in described anchor bar body;
Stretch-draw termination, is arranged on anchor bar body one end, is provided with the anchor pole aperture connecting with hollow injected hole on described stretch-draw termination;
Pressure-cliping expansion anchor head, is connected by screw threads for fastening with the other end of anchor bar body stretch-draw termination;
Stop grouting plug, is arranged on the position in the close described anchor pole aperture of described anchor bar body, in case grouting liquid is excessive;
Pallet, is arranged on described anchor bar body by nut is adjustable, and withstands described stop grouting plug;
Slipmat, is arranged between pallet and nut;
Dop, is arranged on described stretch-draw termination outermost end.
Preferably, described anchor bar body is provided with conical elongation frictional resistance section, extending in stretch-draw effect inferior pyramidal elongation frictional resistance section; Anchor bar body total length is provided with and increases resistance screw thread and protruding tooth.
Preferably, described pressure-cliping expansion anchor head expands into the horizon bar of 90 ° of 4 angles under pushing effect.
Preferably, described pallet can deform under quick-fried punching effect.
The present invention utilizes pushing force that pressure-cliping is expanded to the horizon bar that anchor head expands into 90 ° of 4 angles anchored end is provided, use hollow injected hole to inject slurries in bolthole, stretching anchor rod body, slurries solidify strengthening synchronizes with putting, increase frictional resistance by anchor bar body conical elongation frictional resistance section, protruding tooth and increasing resistance screw thread, realize from slip casting, total length is stressed and increase resistance, anchoring stratum compactness increases, intensity improves, can stop water infiltration, pallet deformable under quick-fried punching effect is avoided destroying.
That the present invention is applicable to is moisture, the resistance of toxic gas stratum blends rock-soil layer and reinforces fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is pressure-cliping expansion anchor head ground plan;
Fig. 3 is pressure-cliping expansion anchor head contraction state structure chart;
Fig. 4 is pressure-cliping expansion anchor head expansion state structure chart.
The specific embodiment
As shown in Figure 1, self-filled type total length of the present invention increases to stop oozes joint control antiknock and rushes anchor pole and comprise: anchor bar body 1, pallet 6 and pressure-cliping expansion anchor head 12, in anchor bar body 1, be provided with hollow injected hole 10, anchor bar body 1 one end adopts screw threads for fastening to be connected with pressure-cliping expansion anchor head 12, anchor head 12 expands into circular discs under pushing effect, thereby anchored end is provided.
Anchor bar body 1 other end is provided with stretch-draw termination 11, on stretch-draw termination 11, be provided with the anchor pole aperture 13 connecting with hollow injected hole 10, stop grouting plug 5 is arranged on the position in the close anchor pole aperture 13 of anchor bar body 1, pallet 6 withstands stop grouting plug 5 and prevents that slurries are excessive, and be arranged on anchor bar body 1 by nut 8 is adjustable, pallet 6 is arranged on anchor bar body 1 by nut 8 is adjustable, between pallet 6 and nut 8, is provided with slipmat 7, pallet 6 deforms after class in quick-fried punching effect, prevents that anchoring Rock And Soil from destroying.
11 outer ends, stretch-draw termination are provided with dop 9.
Anchor pole is put into after boring, first by anchor pole aperture 13 to 10 slip castings of hollow injected hole, stretching anchor rod fastening nut 8 subsequently, slurries solidify strengthening synchronizes with putting, and realizes the stressed increasing prevention of anchor pole total length and oozes.
Anchor pole is inserted after boring to pressure-cliping expansion anchor head 12 in as the contraction state of Fig. 3.
After 10 slip castings of hollow injected hole, stretching anchor rod is put and is opened after injecting paste material rapid solidification, and pressure-cliping expansion anchor head 12 is in Fig. 2, Fig. 4 state.
Anchor bar body 1 is provided with conical elongation frictional resistance section 2, and extending in stretch-draw effect inferior pyramidal elongation frictional resistance section 2, conical elongation frictional resistance section 2 plays the effect that increases frictional resistance.
Anchor bar body 1 total length is provided with and increases resistance screw thread 4 and protruding tooth 3, thereby has greatly increased the frictional resistance of anchor bar body 1 with slip casting rock-soil layer.
The present invention passes through after 10 slip castings of hollow injected hole in the time of work, utilize dop 9 and stretch-draw termination 11 stretching anchor rods, fastening nut 8, after injecting paste material rapid solidification, put and open, stretching force transmits to anchoring stratum by the conical elongation frictional resistance section on pallet and anchor pole, protruding tooth and increasing resistance screw thread, thereby it is stressed from slip casting and total length that anchor pole is realized, and increase its frictional resistance.
Anchoring stratum compactness increase like this, intensity improve, and also can stop water infiltration, and pallet deformable under quick-fried punching effect, avoid damaging, and control anchoring Rock And Soil destroys.
That the present invention is applicable to is moisture, the resistance of toxic gas stratum blends rock-soil layer and reinforces fast.
