Abstract
The utility model relates to a recoverable end support type anchor rod in the field of geotechnical engineering anchoring, which comprises an anchor head (1), an anchor rope (2) and an anchor rope casing (3), wherein the rope casing is sleeved outside the anchor rope (2); the anchor rope (2) and the anchor rope casing (3) are bent; two ends of the anchor rope (2) are positioned at the same end of the anchor rod; and the anchor rope (2) is connected with an anchor head (1). In the recoverable end support type anchor rod, the anchoring force is provided by the anchor head (1); when the anchor rod is used, one end of the bent anchor rope (2) is released and a pull force is applied at the other end of the anchoring rope for recovering; since the anchor rope casing (3) is sleeved outside the anchor rope (2) which can slide relative to the anchor rope casing (3), so that the anchor rope (2) is convenient to recover with high recovery rate and the anchor rod has low cost and reliable quality.
Description
Technical field
The present invention relates to geotechnical engineering anchoring field.
Background technology
Along with engineering construction developing rapidly of underground space development particularly, demand to anchor pole in engineering constructions such as bracing of foundation pit, slope retaining increases day by day, and cause contiguous place underground space development difficulty owing to often leave over the body of rod after the anchor pole use at present in adjacent domain, limited the application of anchor pole to a great extent.In order to realize the recovery of anchor bar body, existing callable anchor pole mainly contains construction technologies such as various anchor poles by the mechanical whorl connection, the detachable anchor pole of U type.The nearest documents of callable anchor pole is a Chinese patent 01234117.7, this technology and other recoverable anchor rod technology all are to adopt the link technique of screw thread-like, mechanical movement by the body of rod makes deviates from the never recyclable body of the callable beaer of anchor pole after using, thereby reaches the purpose that reclaims the body of rod.There is following defective in this technology: one, and with recyclable body and can not recovery body connect, manufacture craft is complicated, the cost height by mechanical connection manner for prior art; They are two years old, behind the anchor bolt construction, because anchor pole is difficult to keep original linear state in drilling construction, deadweight and loading process, thereby the motion modes such as rotation of anchor pole when reclaiming is difficult to realize, engineering experience confirms, when anchor pole is longer (as the soil nailing in the present soil nailing wall foundation pit support), be difficult to realize the purpose that reclaims, so such callable anchor pole is difficult to wide popularization and application in field of civil engineering.The second class recoverable anchor rod is the detachable anchor pole of U-shaped, this technology is that high strength steel strand is curved U-shaped, then U shaped steel twisted wire is positioned in the armature boring, is used to complete the back by discharging an end of U-shaped steel strand, and apply pulling force at the other end, steel strand are pulled out recovery by force.The shortcoming of this technology is: the first, this technology in use, the suffered distributed force of steel strand direction along the line is little and inhomogeneous; The second, pulling force is big during recovery, and recovery difficult is big; The 3rd, this technique building technology complexity, cost height.Because above defective though this technology has occurred for many years, still is difficult to promote so far.
The content of invention
First purpose of the present invention is to provide a kind of callable end to hold the formula anchor pole, this callable end holds the formula anchor pole can provide bigger anchored force, and can realize the recycling of anchor bar body, reduce the influence of anchor pole to peripheral underground space development, enlarge the application of anchor pole, reduce engineering cost significantly.
This callable end holds the formula anchor pole and comprises that anchor head, anchor cable and anchor cable sleeve pipe three parts form, the anchor cable casing pipe sleeve outside anchor cable, anchor cable and anchor cable casing buckling, the anchor cable two ends are positioned at the same end of anchor pole, anchor cable is connected with anchor head.
Second purpose of the present invention is to provide the callable end of a kind of pressure dispersing type to hold the formula anchor pole, the callable end of this pressure dispersing type holds the formula anchor pole can provide bigger anchored force, and can realize the recycling of anchor bar body, reduce the influence of anchor pole to peripheral underground space development, enlarge the application of anchor pole, reduce engineering cost significantly.
The callable end of this pressure dispersing type holds the formula anchor pole and is included in the different extension position of burying and arranges that two covers or the above callable end of two covers hold the formula anchor pole, the callable end of every cover holds the formula anchor pole and comprises anchor head, anchor cable and anchor cable sleeve pipe three parts composition, the anchor cable casing pipe sleeve is outside anchor cable, anchor cable and anchor cable casing buckling, the anchor cable two ends are positioned at the same end of anchor pole, and anchor cable is connected with anchor head.
Because callable end of the present invention holds the anchor cable of formula anchor pole and is with the anchor cable sleeve pipe outward, when utilizing anti-pulling of anchor bar, can the anchor cable two ends of bending are fixing simultaneously, utilize anchor head that anchored force is provided, after anchor pole is finished using, one end of the anchor cable of bending can be discharged, applying pulling force at the other end of anchor cable reclaims anchor cable, because of anchor cable is with the anchor cable sleeve pipe outward, can slide relatively between anchor cable and the anchor cable sleeve pipe, so that anchor cable reclaims is convenient, rate of recovery height, the anchor pole cost is low, provides anti-pulling of anchor bar by anchor head, the anchor pole reliable in quality.

Fig. 1 holds formula anchor structure schematic diagram for callable end of the present invention.
The specific embodiment
Hold an embodiment of formula anchor pole as callable end of the present invention, at first in the soil body, hole, as shown in Figure 1 callable end is held the formula anchor pole put into boring, in boring, inject cement paste then, after treating that cement slurry solidifies, callable end is held the two ends of the anchor cable (2) of formula anchor pole and carry out stretch-draw and fixing simultaneously, the anchor head (1) that can utilize callable end to hold the formula anchor pole provides anti-pulling capacity, after finishing using, to be positioned at an end constraint relief of the anchor cable (2) that callable end holds the formula anchor pole, the other end at anchor cable (2) applies pulling force, and under the effect of anchor cable sleeve pipe (3), cement slurry does not contact with anchor cable (2) and produces bond stress, therefore anchor cable (2) can be reclaimed easily, the recovery pulling force is little, and it is convenient to reclaim, rate of recovery height.In the present embodiment, two covers or the above above-mentioned callable end of two covers are held the different depths that the formula anchor pole places boring, just formed the callable end of pressure dispersing type and held the formula anchor pole.
This patent includes but not limited to other job practicess of the alternative use of professional person in this area.
