Abstract

The utility model relates to a retrievable rockbolt. The screw connection of a steel pull rod and a movable anchor head is adopted in the utility model, and a PVC water strainer is sheathed outside the steel pull rod, and the steel pull rod is made to be completely retrievable, repeatedly used, with construction cost saved, and synchronously other obstacles of engineering construction carried out in the vicinity of the utility model are eliminated. The PVC water strainer is fixed by the base of the movable anchor head, after steel pull rod is pulled out, small bores on the PVC water strainer can be mutually penetrated when cement mortar is injected in the PVC water strainer. The utility model is of much lower cost, and the utility model can be integrally produced in batches in factory.

Description

A kind of reclaiming type anchor bar entirely
Technical field
The utility model relates to a kind of anchor pole, the recoverable anchor pole that uses in particularly a kind of foundation ditch and the interim stabilization works of side slope.
Background technology
Before the present utility model, anchor pole needs reinforcement to foundation ditch and side slope etc. as a kind of that employed technology has obtained using quite widely in the middle of the engineering, its know-why is at first at the stabilization zone pore-forming, be that anchor pole is put into the hole then with reinforcing pull rod, again with cement mortar to the anchoring of being in the milk of anchor pole end, the pulling force that anchor pole bore is delivered in the cement mortar by anchor pole periphery bond stress earlier, and secondly the frictional resistance by cement mortar anchoring section and stratum is delivered in the good ground of stabilization zone.After the structure construction was finished, reinforcing pull rod was that anchor pole is just stayed in the soil layer.
This anchor pole technology can not reclaim the waste of material that is brought for interim stabilization works such as foundation ditch, side slope and anchor jacked pile is existed, the defectives such as cost of engineering construction have been increased virtually, the anchor pole of staying simultaneously in the soil layer also can influence anchor pole other engineering construction on every side, as the construction in pipeline such as coal gas, tap water, cable and places such as subway, underground store and passage, increased constructional difficulties and construction cost for these engineerings.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, design, a kind of reclaiming type anchor bar entirely of development.
The technical solution of the utility model is: a kind of reclaiming type anchor bar entirely, its major technique are characterised in that reinforcing pull rod is connected with movable anchor head spiral, socket PVC floral tube outside reinforcing pull rod.
Advantage of the present utility model and effect are that anchor pole can use repeatedly, have saved construction cost, and the while is again neighbouring later on or other construction works has on every side been got rid of obstruction, has also saved the operating expenses of these engineerings, has reduced difficulty of construction.And the utility model is simple in structure, easy to operate, does not influence current construction and quality again, also can not bring other future trouble, the protection environment.The utility model can be integrated into product, produces in batches in factory.
Description of drawings
Fig. 1---the utility model structural representation.
Fig. 2---the I-I figure among Fig. 1.
The concrete application schematic diagram of Fig. 3---the utility model in construction works.
The specific embodiment
As shown in Figure 1 and Figure 2, at first reinforcing pull rod 1 (anchor pole) end (top) is connected with movable anchor head 2 spirals, but spiral tighten, but also spiral is unscrewed until unclamping, breaking away from; In this example, movable anchor head 2 is recessed formula nut structures, and corresponding with it reinforcing pull rod 1 is protruding formula, and spiral connects, the also protruding formula nut structure of certain movable anchor head 2, with corresponding reinforcing pull rod 1 be recessed formula, spiral connects; Socket PVC floral tube 3 outside reinforcing pull rod 1, between reinforcing pull rod 1 and PVC floral tube 3, there are space or space, PVC floral tube 3 tops and movable anchor head 2 are fixing, mainly be to utilize ledge on the movable anchor head 2, ledge as protruding formula nut, one circle ledge also is set on its base plane, gets final product with fixing PVC floral tube 3.
As shown in Figure 3, in using the utility model, pore-forming 4 in ground is put into hole 4 with forming integrative-structure after reinforcing pull rod 1, movable anchor head 2, PVC floral tube 3 assembling in advance earlier, the silt particle of pouring water between PVC floral tube 3 and hole 4 then slurry makes it to form bolt anchorage system 5; After treating that interim stabilization works finishes, reinforcing pull rod 1 backpitch from movable anchor head 2 is rotated, withdraw from movable anchor head 2, thereby take out reinforcing pull rod 1, and be to take out reinforcing pull rod 1 fully, do not waste any one section or a joint reinforcing pull rod 1, make this reinforcing pull rod 1 can use cost saving repeatedly; Movable anchor head 2 bases can be made into square, have edges and corners, and rotate when pulling out so that prevent reinforcing pull rod 1, and movable anchor head 2 is also taken out of; Because reinforcing pull rod 1 is removed, avoid adding to the difficulties to other engineering construction around it.After just pull bar 1 has taken out, if necessary, also can pour into cement mortar in PVC floral tube 3, the aperture 6 on the PVC floral tube 3 helps PVC floral tube 3 inside and outside cement mortar and interpenetrates with consolidated subsoil.
