Description
Technical field
The invention belongs to the ground anchorage technical field, relate to a kind of vibration balancing anchor device.
Background technology
Anchor pole, anchor cable are widely used in the anchoring engineering of side slope, underground chamber, tunnel and the foundation ditch of major workss such as railway, highway, mine, water conservancy and civilian construction.In these engineerings, there is one type of problem comparatively outstanding.Be to have such as locomotive vibration, mine in the anchoring system working range to adopt or construction blasting; The existence of these vibration sources can make anchoring system receive the effect of the load that moves in circles for a long time, the perhaps effect of transient peak stress; Cause the excessive ess-strain loss of anchor cable; Produce over-large displacement, even moment stress breakthrough anchor cable ultimate load, the anchoring failure damage caused.Jeopardize locomotive operation security, equipment, personnel's life security.
Current anchoring generally adopts anchor dish, intermediate plate and anchor cable matching and fixing paying the waist rail that protects on the soil body in advance or connecting beam and loaded plate is worked simultaneously, to reach the purpose of soil mass consolidation.Concrete sequence of construction is following:
1. set anchor hole.
2. insert anchor cable and slip casting.
3. the company's of setting beam and loaded plate are provided with hole so that pass anchor cable in the middle of the loaded plate.
4. work as the slip casting slurry and reach setting intensity; Anchor cable is passed anchor dish corresponding perforations one by one, and use intermediate plate to clamp in the hole on the anchor cable mooring anchor dish, use anchor pole stretch-draw jack; Apply certain prestressing force; And the locking intermediate plate, make intermediate plate clamp anchor cable, intermediate plate is fixed in the corresponding hole of anchor dish.
5. finish, the anchor pole system is started working, and the soil body obtains reinforcing.
This type of anchoring process receives under the vibration condition at the soil body elastic deformation takes place, through the elasticity volume expansion with shrink anchor head generation effect; Soil expansion increases the anchor head load, its moment peak stress possibly destroy anchor head (anchor cable), cause anchoring to be lost efficacy; Cause security incident, or destroy intermediate plate and produce loss of prestress, soil body elastic shrinkage can reduce anchor head prestressing force moment; This effect that continues repeatedly can destroy anchor head or cause its loss of prestress, jeopardizes engineering safety.
Summary of the invention
The objective of the invention is to propose a kind of vibration balancing anchor device, vibration controlling structure is combined with anchor cable, increase the whole shock resistance of anchor device anchor system, the cushion load sudden change improves safety, the reliability of support system to the influence of anchoring system.
The present invention accomplishes the technical scheme that its invention task taked:
A kind of vibration balancing anchor device; Be fixedly connected with pedestal connecting on the loaded plate that beam or waist rail connect firmly with prop; The top of said pedestal is the annular column sleeve of cavity structure; Being provided with top board and said top board is the cavity cylindrical structure, the annular column sleeve of said pedestal upper cavity structure be positioned at top board and relatively top board move axially; In the cavity that the annular column sleeve of pedestal combines with top board to constitute, be provided with Hough formula rubber disc; Said anchor dish fits tightly on the top board top; Described top board has and the tight adjusting bolt of giving of its one; Be positioned at the centre bore that the tight adjusting bolt of giving of top board cavity center passes pedestal, Hough formula rubber disc, have and regulate the clamp nut that bolt thread cooperates, through pedestal Hough formula rubber disc is applied pretightning force giving tight adjusting bolt lower end; Have the anchor cable hole that supplies anchor cable to pass through on the said anchor dish, an end is anchored at anchor cable in the soil layer and passes on loaded plate, pedestal, Hough formula rubber disc, the top board corresponding anchor cable hole successively and be fixedly clamped on the anchor dish by the intermediate plate in the anchor cable hole on the anchor dish.
Between the upper surface of pedestal, annular column sleeve, Hough formula rubber disc, be respectively arranged with locating ring between top board and the Hough formula rubber disc upper surface, move radially in order to prevent Hough formula rubber disc.
Said Hough formula rubber disc can be one or more.
A kind of vibration balancing anchor device that the present invention proposes; Utilize Hough formula rubber super-elasticity deformability; Cushioned the stress that causes by load sudden change or vibration destruction, adopted this vibration balancing anchor device, accomplished reinforcing supporting Foundation Treatment rock-soil layer to anchor pole; Increase the anchor pole balance because the ess-strain sudden change that the load sudden change causes causes the ability of anchor shaft anchor cable system destruction thereby reach, effectively raise safety, the reliability of bolt support system.
