Description
Technical field
The utility model belongs to tunnel construction scene and carries out detection technique field to anchor rod drawing power, and in particular to one
Kind tunnel bends anchor pole anti-pulling force checking device.
Background technique
In Tunnel Engineering, for the firm country rock body excavated, the means generallyd use are that anchor pole is passed through soft stratum,
Competent bed is anchored to be reinforced.It, need to be to the drawing of anchor pole in order to verify whether the anchoring ability of anchor pole reaches design requirement
Power is detected.The method of currently used drawing experiment are as follows: anchor pole one end is passed through into jacking oil pump, after being fixed with anchorage,
It is pressurizeed by hydraulic hand-pump to drawing instrument, according on reading table as a result, determining anchor pole anti-pulling ability.But it is existing
Drawing instrument and anchorage are usually only applicable to that anchor pole is upright, the metope state vertical with anchor pole, due to worker operation carelessness and
The complexity of tunnel construction technology condition, in tunnel anchor pole originally reserved often due to collision, squeeze and bend, it is difficult to cover
Drawing experiment is carried out into drawing instrument hydraulic press, and anchor pole and the face of reinforcing are not exclusively vertical, the drawing direction of drawing instrument cannot be with anchor
Bar installation direction is completely the same, increases the difficulty of test of pulling capacity.
To there are mainly two types of this currently used methods: 1. amputate the bending part of anchor pole, then drawing instrument is inserted in directly
Outside apeak bar, drawing experiment is carried out after inclination angle reinforcing bar or plank leveling, but this method requires the exposed 300mm of remaining anchor pole, wave
Take material, and is limited by the limitation of field material size using the method for temporary backing；2. macropore is inserted on bending part top
In the hollow pipe of diameter, applies bending stress, break straight anchor pole, then tested.This method is when carrying out drawing experiment, due to material
Expect the fatigue damage of itself, can be often broken at former curved position.Meanwhile the pulling capacity that drawing instrument generates cannot be transmitted to anchor pole
With the part of rock contact so that pulling capacity can not be examined.
Summary of the invention
