Abstract
The utility model discloses a recyclable end support ground anchor, which comprises an anchor rod, wherein the lower end of the anchor rod is in threaded connection with a concrete anchor solid poured in rock soil, and the threaded surface of the lower end of the anchor rod is covered with an organic or inorganic isolated layer. The anchor rod is led to have larger fixing force and mainly exerts resistance of the rock soil end, and the anchor rod can be conveniently dismounted and recycled. The use cost is saved. As the structure is simple, the production cost is also saved, and the recyclable end support ground anchor has the good popularization value.
Description
Technical field
The utility model relates generally to the geotechnical engineering field; Be specifically related to the design improvement of supporting with anchor pole; Can be widely used in short engineering of cycles such as slope retaining, pattern foundation pit supporting structure, foundation pile engineering, also can be used for the counter-force anchoring system of the static load test of foundation pile, ground, composite foundation.
Background technology
In the existing various earth anchor technology, the on-disconnectable anchor pole that removes formula is fixed in being of using often, and it also is bar side friction-type that idol has the detachable anchor pole of minority, its carrying form.The frictional force that provided of ground system still is less after all, during like the bigger anchored force of needs, only can just can satisfy instructions for use by increasing anchor bar body diameter and length and quantity, and the cost that causes like this is wasted bigger.
Also have a kind of earth anchor, its structure is: the concrete anchoring body that anchor pole end and is embedded in underground cast is fixedly connected, and anchor pole not only can receive the collateral resistance effect from ground like this, also can receive the effect of its end resistance, increases the anchored force between anchor pole and the ground.
But need the occasion of interim earth anchor for some, above-mentioned earth anchor is just not too suitable, after life cycle is accomplished, can not remove anchor bar body, not only raises the cost, but also possibly stay obstacle to ground.
The utility model content
The utility model technical problem to be solved just provides a kind of end and holds earth anchor, and after construction was accomplished, anchor pole also can be recovered, in order to recycle.
Solve the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of recyclable end holds earth anchor; Comprise anchor pole, the concrete anchoring body of pouring into a mould in described anchor pole lower end and the ground is threaded, and the thread surface of described anchor pole lower end covers the separation layer of organic or inorganic matter.
Described concrete anchoring body is located at reaming place in the rock-soil layer in whole or in part, and so ground produces further end resistance to the concrete anchoring body, further strengthens anchored force.
Described screw thread is the width screw thread, mainly is the comprehensive matching of considering the very low tension of the performance of drawing, press, cutting that steel are higher and concrete anchoring body, cutting ability, and it is convenient to remove anchor pole.
Described concrete anchoring body is an inverted round platform, also can make inverted hemispherical, turbination, frustum etc., increases the suffered end resistance of concrete anchoring body and saves material simultaneously.
During making; At first in the separation layer of the width thread surface brushing organic or inorganic thing of anchor pole lower end; Be positioned over to be drilled into certain depth in advance and to bore and expand in reaming place of rock-soil layer, concreting, treat that hardening of concrete reaches certain intensity after; Anchor bar body is formed with the enlarged body concrete be threaded, the performance end is made usefulness.
Beneficial effect:
1, the utility model is mainly used in provisional anchorage element, contacts through the concrete anchoring body of building in screw thread and the ground, and scribbles separation layer on its contact surface; After construction is accomplished, can anchor pole be screwed out, anchor pole can be recycled repeatedly; Cut the waste, practiced thrift cost greatly, in addition; Anchor pole is in time removed, and does not influence the follow-up construction in place, and is more convenient;
2, the utility model is simple in structure, and cost of production is low, has excellent popularization and is worth.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is the user mode figure of the preferred embodiment of the utility model.
The specific embodiment
As shown in Figure 1; Steel anchor pole 1 is positioned over to be drilled into certain depth in advance and to bore expands, which is provided with width screw thread 2 in reaming place of rock-soil layer, convenient during dismounting; And on screw thread 2 the pre-coated separation layer 3 that is stamped; Build concrete anchoring body 4 then with closely knit, make the moulding of concrete anchoring body, treat to come into operation after concrete anchoring body semi-finals degree reaches designing requirement.Concrete anchoring body 4 is an inverted round platform in the present embodiment; Also can make inverted hemispherical, turbination, frustum etc.; Integral body is located at reaming place in the rock-soil layer; Certainly also can be other different shapes, above face area is good greater than the lower surface, and so not only increasing the suffered end resistance of concrete anchoring body saves material simultaneously.
This moment, anchor pole not only can receive the collateral resistance effect from the concrete anchoring body of ground, cast, also can receive the effect of its end resistance, and in general the end resistance of geotechnical body is much larger than side friction.
When not needing anchor pole, press the rotation direction of screw thread and rotate anchor bar body 1, because the width thread surface on the anchor bar body 1 is provided with separation layer 3; Can make anchor pole 1 screw out concrete anchoring body 4 smoothly; From boring, take out anchor bar body 1 again and reclaim, only stay concrete anchoring body 4 in reaming, anchor bar body 1 can be recycled.
The utility model not only can make anchor pole have bigger bed knife, and (the utility model both can be used as end and has held anchor pole and make resistance to plucking usefulness, also can the upper-lower position of anchoring body be exchanged, and increased bolt diameter; Also can be used as the compressive pile use that end holds); And anchor pole can conveniently remove and recycle, and not only saved use cost, and it is simple in structure; Saved cost of production equally, had excellent popularization and be worth.
