Abstract
The utility model discloses a full-thread glass fiber composite hollow grouting anchor rod which comprises a grouting pipe. Multiple spiral rib steel wire lines are wound outside the grouting pipe. A connector is fixedly installed at the other end of the grouting pipe. A slurry-blocking plug is arranged on the outer side of the connector in a blocking mode. A slurry-blocking valve, a supporting plate, and a rigging core are fixedly arranged outside the multiple spiral rib steel wire lines in a sleeved mode. A rigging sleeve is arranged on the outer cone face of the rigging core in a matched mode. An expanding plug is arranged between the front portion of the grouting pipe, and the multiple spiral rib steel wire lines. The full-thread glass fiber composite hollow grouting anchor rod has the advantages of being high in strength, good in plasticity, low in flabby valve, good in unbending performance, and the like. Meanwhile, due to the fact that the thickness of a built-up arch is enlarged, load concentration degree acted on a baseplate is reduced, and therefore stress of a rock of the baseboard is reduced.
Description
Technical field
The utility model relates to the compound hollow grouting anchor of full thread glass fiber.
Background technology
Grouted anchor bar mainly is the geotechnical anchor engineering for aspects such as tunnel construction, slope treatment, foundation ditch armlet, minings.The steel strand Mine anchorage cable is comprised of steel strand, pallet, anchor cable.In the prior art, mainly there is following shortcoming in grouted anchor bar:
1, adopt sub-thread, the anchor cable supporting capacity is little, and supporting intensity is low, and the boring utilization rate is low;
2, the anchor cable diameter is less than normal, does not meet reasonably " three footpaths " matching relationship, and the annular thickness that forms after resin anchoring agent solidifies reaches more than the 6mm, and anchored force is had adverse effect,
3, the anchor cable diameter is less than normal, and the weak effect of agitating resin in installation process easily reduces anchorage cable anchoring power because resin anchoring agent packaging bag plastic sheeting wraps " Double-skin " that steel strand form, and does not have due support action; In a single day anchor cable is partially soft, bends easily under the anchor pole thrust during installation, and deviates from, because anchor cable elasticity is large, hurt sb.'s feelings easily, sometimes also can install unsuccessfully because hardening of resin causes.
The utility model content
The purpose of this utility model provides the compound hollow grouting anchor of a kind of full thread glass fiber, have the characteristics such as intensity height, good, the lax value of plasticity is low, stretching property is good, simultaneously because the increasing of built-up arch thickness, reduce so again to act on the Load concentration degree on the base plate, thereby reduce the stress of floor rock.
The technical solution of the utility model is as follows:
The compound hollow grouting anchor of full thread glass fiber, include Grouting Pipe, described Grouting Pipe is wound with many helix rib steel silk threads outward, the Grouting Pipe other end is installed with connector, stifled being equipped with in the connector outside blocked up the slurry plug, many helix rib steel silk threads are fixed suit grouting stop-valve, pallet, rigging core outward, and rigging core male cone (strobilus masculinus) is combined with the rigging cover, are provided with the expansion plug between Grouting Pipe front portion and the helix rib steel silk thread.
Be equipped with pad between described connector and the stifled slurry plug.
The beneficial effects of the utility model are as follows:
1, adopts novel spiral ribs prestress wire, material is a kind of novel deforming steel wire, its main feature is the last plastic strain drawing of semiproduct process after the calendering drawing process is processed, so that Steel Wire Surface forms 6 continuously spiral ribs of projection, spiral ribs is integrated with basic circle, jointly forms the steel wire in same cross section.Have the characteristics such as intensity height, good, the lax value of plasticity is low, stretching property is good;
2, anchor cable adopts novel hollow structure, carries Grouting Pipe, adopts reverse grouting mode, has not only eliminated the possibility that produces the air pocket cavity, guarantees that the anchoring slurries are full of boring, and has saved the special joint of stack and Grouting Pipe, has simplified working procedure.
3, after the slip casting so that act on the vertical load of top board and can effectively be delivered to two and help, the reinforcing by to side can be delivered to base plate to load again; Because the increasing of built-up arch thickness reduces so again to act on the Load concentration degree on the base plate, thereby reduces the stress of floor rock, weaken the plastic strain of base plate simultaneously, alleviate end distension; And base plate is stable, help two help stable, help in the stable situation at base plate and two, can keep again the stable of top board.
4, adopt novel retaining mechanism, have aligning function, the little and uniformity of anchor cable protruded length, the tight lock of exposed junction is reliable, non-slip, spark do not occur, does not affect the tunnel effective support.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the compound hollow grouting anchor of full thread glass fiber, include Grouting Pipe 1, be wound with many helix rib steel silk threads 2 outside the Grouting Pipe 1, Grouting Pipe 1 other end is installed with connector 3, and stifled being equipped with in connector 3 outsides blocked up slurry plug 4, many helix rib steel wire 2 lines are fixed suit grouting stop-valve 5, pallet 6, rigging core 7 outward, rigging core 7 male cone (strobilus masculinus)s are combined with rigging cover 8, are provided with expansion plug 10 between Grouting Pipe 1 front portion and the helix rib steel silk thread 2, and connector 3 and stifled slurry are equipped with pad 9 between filling in 4.
Claims (2)
1. the compound hollow grouting anchor of full thread glass fiber, include Grouting Pipe, it is characterized in that: described Grouting Pipe is wound with many helix rib steel silk threads outward, the Grouting Pipe other end is installed with connector, stifled being equipped with in the connector outside blocked up the slurry plug, many helix rib steel silk threads are fixed suit grouting stop-valve, pallet, rigging core outward, and rigging core male cone (strobilus masculinus) is combined with the rigging cover, are provided with the expansion plug between Grouting Pipe front portion and the helix rib steel silk thread.
2. the compound hollow grouting anchor of full thread glass fiber according to claim 1 is characterized in that: be equipped with pad between described connector and the stifled slurry plug.
