Description
Technical field
The utility model relates to rearmounted body of rod formula anchor structure.
Background technology
Bolt support is a kind of its support reinforcement mode often adopted in the earth's surface engineerings such as side slope, ground deep foundation ditch and the underground construction such as tunnel, stope.Existing anchor rod construction method is first holed at pre-anchorage point, the aperture of boring is generally 90-200mm, then metalwork, wooden piece, polymer member or other material are made anchor rod body and be placed in boring, common anchor rod body is reinforcing bar or steel strand, and bottom Grouting Pipe being deep into boring with anchor rod body is with to slip casting in boring.Existing this anchor rod construction method Problems existing is: because the aperture of boring is general less, and the anchor pole being placed in boring in advance can take certain space, this just causes the caliber of Grouting Pipe can not be too large, Grouting Pipe is not by concrete slurry that granularity is larger, the combination slurries such as mortar slurry, thus cause in existing anchor rod construction method, slurry eventually to injection in boring can only be the cement paste slurry that granularity is less, cement paste forms combination anchor rod body and borehole wall being solidified into integrative-structure, but due to the combination limited strength of grout cures, compressive strength can not be obtained for anchor rod body and supporting body provide enough large, thus reduce the pulling test strength of anchor pole.Cause combination and borehole wall and the adhesion between combination and anchor pole very limited, finally cause the strength deficiency of whole anchor structure, there is certain potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of rearmounted body of rod formula anchor structure, causes anchor rod body to occupy the problem of borehole space to solve in prior art because first putting anchor rod body.
In order to solve the problem, in the utility model, the technical scheme of rearmounted body of rod formula anchor structure is:
Comprise boring, combination slurry is marked with in boring, rearmounted body of rod formula anchor structure also comprises rear-mounted anchor pole, rear-mounted anchor pole comprises the rear-mounted anchor rod body for inserting from outside to inside in use in described combination slurry, and described rear-mounted anchor rod body is consolidated into integrative-structure by combination slurry and described borehole wall.
Described combination slurry is concrete slurry or mortar slurry.
Described rear-mounted anchor rod body is rigidity or rods structure, and rear-mounted anchor rod body lower end is provided with supporting body, and the lower end periphery face of supporting body is that diameter becomes large taper surface gradually from the bottom to top.
Described rear-mounted anchor rod body is provided with in the top of described supporting body for the centering locating support with described borehole wall location fit, and the outer peripheral face of centering locating support comprise that diameter from top to bottom becomes large gradually upper conical section, from the bottom to top diameter become large inferior pyramidal section and the cylindricality righting section between upper and lower conical section gradually.
The aperture of described boring is 80 ~ 600mm.
The beneficial effects of the utility model are: the utility model adopts rear-mounted anchor pole, after first injecting combination slurry in the borehole again by rear-mounted anchor rod body from outside to inside be placed to combination slurry, like this in slip casting process, rear-mounted anchor rod body can not occupy the space of boring, in combination slurry injection hole that can be higher by structural strength larger for granularity, thus ensure that the combination slurry after solidification has enough large compressive strength, substantially increase the pulling test strength of anchor pole.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of rearmounted body of rod formula anchor structure in the utility model.
Detailed description of the invention
The embodiment of rearmounted body of rod formula anchor structure is as shown in Figure 1: comprise boring 5, boring aperture 250mm, combination slurry 3 is marked with in boring, in the present embodiment, combination slurry is concrete slurry, there is in concrete slurry the large grain aggregate that granularity is larger, large grain aggregate is stone, and the granularity of this kind of large grain aggregate is often at more than 5mm, and the total intensity therefore after solidification is better.Rearmounted body of rod formula anchor structure also comprises rear-mounted anchor pole, rear-mounted anchor pole comprises the rear-mounted anchor rod body 1 for inserting from outside to inside in use in combination slurry, rear-mounted anchor rod body upper end is provided with anchor head, and rear-mounted anchor rod body 1 is consolidated into integrative-structure by combination slurry 3 and borehole wall.In the present embodiment, rear-mounted anchor rod body is made up of the reinforcing bar of rigid rod structure, rear-mounted anchor rod body can be made to be inserted in combination slurry from outside to inside by vibratory equipment, rear-mounted anchor rod body lower end is provided with supporting body 4, the lower end periphery face of supporting body 4 is that diameter becomes large taper surface gradually from the bottom to top, the upper surface of supporting body is the plane that bearing of trend is vertical with above-below direction, the lower surface outer peripheral face structure of supporting body is conducive to the lower smoothly of rear-mounted anchor pole and inserts, and the upper end surface structure of supporting body is conducive to the bearing capacity ensureing rear-mounted anchor pole.Rear-mounted anchor rod body is provided with in the top of supporting body for the centering locating support 2 with borehole wall location fit, spacing between two centering locating supports is 1500 ~ 2000mm, and the outer peripheral face of centering locating support comprise that diameter from top to bottom becomes large gradually upper conical section, from the bottom to top diameter become large inferior pyramidal section and the cylindricality righting section between upper and lower conical section gradually.The rearmounted anchor pole that refers in the utility model is placed in combination slurry after slip casting.
In other embodiment of this rearmounted body of rod formula anchor structure: boring aperture can also be other value beyond 80mm, 100mm, 200mm, 250mm, 500mm, 600mm or 80 ~ 600mm; Concrete slurry can also be replaced by mortar slurry, cement paste slurry or other combination slurry; Supporting body also can not be established, and the parcel now between dependence anchor rod body and combination slurry ensures the bonding strength between rear-mounted anchor rod body and combination slurry; Rear-mounted anchor rod body can also be steel strand, carbon fiber etc., because steel strand are softer, so rear-mounted anchor rod body is being placed in conjunction with in slurry process, need by drilling tool, such as drilling tool is arranged on supporting body (Follow-up type supporting body), steel strand are connected on supporting body, drilling tool in the process piercing combination slurry by anchor rod body band people in combination slurry, rear-mounted anchor rod body is inserted in combination slurry with supporting body, when after arrival designated depth, propose drilling tool, rear-mounted anchor rod body has just been stayed in combination slurry; The hole depth of boring both can have been carved and extended along the vertical direction, also can extend in the horizontal direction, can also be inclined to certain angle extend with horizontal direction.
