The utility model discloses an it can increase the effective length of stock to add long anchor rod, can draw the experiment to the stock that awaits measuring of reserving insufficient length to ensure engineering quality, reduced safety accident's emergence.
Description
Technical field
The utility model belongs to Tunnel Engineering technical field, is specifically related to a kind of tunnel anchor pole pull-out test counterforce device.
Background technology
In the structural concrete reinforcing engineerings such as highway subgrade slope reinforcing, the supporting of tunnel surrounding initial stage, Tunnel Second Lining concrete strengthening, bridge, anchor pole can increase the concrete cohesive force of post-reinforcing effectively, increase slip resistance and supporting capacity, therefore the anchor force of anchor pole is very important data, in order to the anchor force of testing inspection crotch anchor pole, general application drawing instrument screw block carries out pull-out test detection.
In existing anchor pole pull-out test, generally all require the reserved certain length (about 30cm) of test anchor shaft anchor cable, to ensure the enforcement of pull-out test. Pre-allowance is too short, does not just possess test conditions, cannot carry out the testing inspection of anchor pole drawing. In order to accomplish the random inspection to anchor bolt construction quality, a lot of unit in charge of construction utilizes the drawback of this length in reserve, by the anchor shaft anchor cable to be checked of length in reserve, strictly constructs on request, and detected result is complete qualified existing; And the anchor shaft anchor cable of non-length in reserve, then to use inferior materials and turn out substandard goods, the construction quality extreme difference of anchor shaft anchor cable, makes pull-out test implement, and seriously affects the quality of tunnel surrounding and side slope.
Practical novel content
In view of this, the purpose of this utility model is to provide a kind of tunnel anchor pole pull-out test counterforce device, to solve the problem that cannot carry out effective pull-out test and cause seriously affecting tunnel surrounding and side slope quality that prior art exists owing to anchor pole length in reserve is not enough.
The purpose of this utility model is achieved through the following technical solutions:
A kind of tunnel anchor pole pull-out test counterforce device, comprise the ground tackle that can act on anchor pole by drawing force and ground tackle is applied the screw block of drawing force, also comprise the lengthening anchor pole being connected and fixed by adapter sleeve and anchor pole and the support set supported by screw block, described lengthening anchor pole passes the hole of crossing arranged on support set, screw block successively and is connected with ground tackle fastening, support set, screw block, ground tackle is pressed on together on tunnel surrounding.
Further, described support set is the cylindrical steel cylinder that one end open one end is closed, and is provided with protecting sheet between its opening end and tunnel surrounding, and described screw block acts on the outer face of blind end.
Further, between described adapter sleeve with anchor pole and lengthening anchor pole, all employing is threaded.
Further, the axis of described lengthening anchor pole overlaps with the axis of support set and screw block.
The beneficial effects of the utility model are:
The utility model can increase the useful length of anchor pole by lengthening anchor pole, the anchor shaft anchor cable to be measured of length in reserve deficiency can be carried out effective pull-out test, guaranteeing construction quality, in farthest preventing tunnel surrounding or slope project to reinforce, the phenomenon of using inferior materials and turning out substandard goods of anchor shaft anchor cable occurs; Meanwhile, also solve, by support set, the difficult problem that tunnel anchor pole pulling test screw block not easily fixes.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model. Target of the present utility model and other advantages can be realized by specification sheets below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is the structural representation of a kind of tunnel of the utility model anchor pole pull-out test counterforce device.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail. It is to be understood that preferred embodiment is only in order to illustrate the utility model, instead of in order to limit protection domain of the present utility model.
As shown in the figure, a kind of tunnel anchor pole pull-out test counterforce device of the present embodiment, comprise the ground tackle 2 that drawing force can be acted on anchor pole 8 and the screw block 3 that ground tackle 2 is applied drawing force, also comprise the lengthening anchor pole 1 being connected and fixed by adapter sleeve 5 and anchor pole 8 and the support set 4 supported by screw block 3, described lengthening anchor pole 1 is successively through support set 4, the hole of crossing arranged on screw block 3 is connected fastening with ground tackle 2, it is beneficial to support set 4, screw block 3, ground tackle 2 is pressed on tunnel surrounding 7 together, carry out pull-out test, when specifically implementing, by support set 4, the hole of crossing of screw block 3 is arranged on respective center, even if the axis lengthening anchor pole 1 overlaps with the axis of support set 4 and screw block 3, make drawing force proportionality action in lengthening on anchor pole, obtain result accurately.
By lengthening, former anchor pole can effectively be lengthened the present embodiment by anchor pole, the anchor shaft anchor cable to be measured of length in reserve deficiency can be carried out effective pull-out test, can guaranteeing construction quality, in farthest preventing tunnel surrounding or slope project to reinforce, the phenomenon of using inferior materials and turning out substandard goods of anchor shaft anchor cable occurs; Meanwhile, also solve, by support set, the difficult problem that tunnel anchor pole pulling test screw block not easily fixes.
In the present embodiment; the cylindrical steel cylinder that described support set 4 is closed for one end open one end; tensile strength is higher; bearing capacity is strong; being provided with protecting sheet 5 between its opening end and tunnel surrounding 7, described screw block acts on the outer face of blind end, and protecting sheet 5 increases and tunnel surrounding contact area; reduce footprint pressure, it is to increase the accuracy of its bearing capacity and experiment.
In the present embodiment, all adopt between described adapter sleeve 5 with anchor pole 8 and lengthening anchor pole 1 and it is threaded, being threaded relatively, other flexible connection can be shorter, the risk that minimizing cannot be tested, simultaneously, it is possible to carry out the regulation of length of thread, raising can test rate, meanwhile, also fast and easy connects, it is to increase conventional efficient.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to better embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, and not departing from objective and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
