Description
Technical field
The present invention relates to a kind of self-filled type total length to increase prevention and ooze joint control antiknock and rush anchor pole.
Background technology
Bolt anchorage is the engineering that geotechnical engineering field is commonly used, and serves good reinforce stabilization effect to broken rock or caving ground.
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 reinforces rear anchor bar body increasing resistance, and stressedly to concentrate 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 needs to inject chemical grout to termination point of anchor rod, there is the problems such as cost rising, complex procedures and contaminated environment, and Shi Hanzhang is little; Cartridge bag anchoring utilizes 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 ensure that anchor pole is positioned at center, and Shi Hanzhang is also very little.
Summary of the invention
The invention provides that a kind of Shi Hanzhang is large, free from environmental pollution and simple self-filled type total length of constructing increases prevention oozes joint control antiknock and rush anchor pole.
Self-filled type total length of the present invention increases prevention and oozes joint control antiknock and rush 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, and described stretch-draw termination is provided with the anchor pole aperture connected with hollow injected hole;
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 convex tooth.
Preferably, described pressure-cliping expansion anchor head expands into the horizon bar of 4 angles 90 ° under pushing effect.
Preferably, described pallet can deform under quick-fried punching effect.
The present invention utilizes pushing force to be expanded by pressure-cliping, and horizon bar that anchor head expands into 4 angles 90 ° provides anchored end, hollow injected hole is used to inject slurries in bolthole, stretching anchor rod body, grout cures strengthening with put synchronous, increase frictional resistance by anchor bar body conical elongation frictional resistance section, convex 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 permeation, pallet deformable under quick-fried punching effect is avoided destroying.
The present invention is applicable to the resistance of moisture, toxic gas stratum and blends rock-soil layer rapid reinforcement.
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.
Detailed description of the invention
As shown in Figure 1, self-filled type total length of the present invention increases prevention and oozes joint control antiknock and rush anchor pole and comprise: anchor bar body 1, pallet 6 and pressure-cliping expansion anchor head 12, hollow injected hole 10 is provided with in anchor bar body 1, anchor bar body 1 one end and pressure-cliping are expanded anchor head 12 and are adopted screw threads for fastening to be connected, anchor head 12 expands into circular discs under pushing effect, thus provides anchored end.
Anchor bar body 1 other end is provided with stretch-draw termination 11, stretch-draw termination 11 is provided with the anchor pole aperture 13 connected 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 slurries excessive, and being 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, is provided with slipmat 7 between pallet 6 and nut 8, pallet 6 deforms after class in quick-fried punching effect, prevents anchoring Rock And Soil from destroying.
Outer end, stretch-draw termination 11 is provided with dop 9.
After anchor pole puts into boring, first by anchor pole aperture 13 to hollow injected hole 10 slip casting, stretching anchor rod fastening nut 8 subsequently, grout cures strengthening with put synchronous, realize the stressed increasing prevention of anchor pole total length and ooze.
After anchor pole being inserted boring, pressure-cliping expansion anchor head 12 is in the contraction state as Fig. 3.
After hollow injected hole 10 slip casting, stretching anchor rod, puts and opens 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 increasing frictional resistance.
Anchor bar body 1 total length is provided with and increases resistance screw thread 4 and convex tooth 3, thus considerably increases the frictional resistance of anchor bar body 1 and slip casting rock-soil layer.
The present invention is operationally by after hollow injected hole 10 slip casting, utilize dop 9 and stretch-draw termination 11 stretching anchor rod, fastening nut 8, put after injecting paste material rapid solidification and open, stretching force is transmitted to anchoring stratum by the conical elongation frictional resistance section on pallet and anchor pole, convex tooth and increasing resistance screw thread, thus make anchor pole realize from slip casting and total length stressed, and increase its frictional resistance.
Such anchoring stratum compactness increases, intensity improves, and also can stop water permeation, and pallet deformable under quick-fried punching effect, avoid damaging, control anchoring Rock And Soil destroys.
The present invention is applicable to the resistance of moisture, toxic gas stratum and blends rock-soil layer rapid reinforcement.
