Description
Technical field
The utility model relates to a kind of test devices, and in particular to a kind of anchor pole drawing group experiment displacement measurement system.
Background technique
Geotechnical engineering anchorage technology enables ground anchorage to give full play to strengths of rock and soil using anchor pole as technical measures, increases
Add the self-stable ability of precipice body, to mitigate works self weight significantly, saves engineering material, it is ensured that construction safety and engineering stability.
Suspension roof support has developed into the main support form of underground engineering, in mine, traffic, building, water conservancy and hydropower, military people's air defense etc.
It is had been more and more widely used in engineering.Occupy indispensable indispensable status in geotechnical engineering and underground engineering.
Therefore, the detection of anchor bolt construction quality plays an important role to guarantee engineering safety.
China has " rock soil anchor (rope) technical regulation " (CECS22 2005), " Technique Code for Building Slope Engineering " (GB
50330-2013), a series of rule such as " rock soil anchor and concrete spraying support engineering legislation " (GB 50086-2015)
Model has made related request, test of the anchor rod drawing test as evaluation anchor pole bearing capacity, in anchor to the detection of construction quality of anchor pole
Very important effect is played in the evaluation of bar construction quality.In the fundamental test and acceptance test of anchor pole, it is required to anchor pole position
Shifting amount measures, and is one of the important parameter for evaluating anchor bolt construction quality.Common displacement measurement side in anchor rod drawing test
Method is to be fixed on dial gauge on bracket by gauge stand, and dial indicator measuring head directly withstands on the enterprising line position shift measurement of anchor pole head.?
It is found in actual tests, in loading procedure, leaves initial position since anchor pole head deflects, the shape of dial indicator measuring head head space
Condition happens occasionally.This method has biggish limitation in detecting at the scene, does not meet the development trend of industry.
Therefore, in the test of existing anchor rod drawing common displacement measuring device there are anchor pole head deflect leave it is initial
Position, measurement error are big.
Utility model content
It is drawn the purpose of the utility model is to provide a kind of anchor pole and dials experiment displacement measurement system, there is measurement error
Small feature.
The technical solution of the utility model includes: a kind of anchor pole, which is drawn, dials experiment displacement measurement system, including tripod, on tripod
It is fixed in side slope by fixing bolt, wedge block is bonded with the inclined-plane of side slope and is set to the middle part of tripod, on wedge block
It is disposed with backing plate, jack, jack piston, sleeve, anchor pole and fixes sleeve, the top of fixes sleeve and fixing bolt
Between be provided with lining rope.
Anchor pole above-mentioned, which is drawn, dials experiment displacement measurement system, is provided with intermediate plate between the sleeve and anchor pole.
Anchor pole above-mentioned, which is drawn, dials experiment displacement measurement system, is provided with fixed screw in the fixes sleeve.
Anchor pole above-mentioned, which is drawn, dials experiment displacement measurement system, and the tripod is equilateral triangle frame.
Anchor pole above-mentioned, which is drawn, dials experiment displacement measurement system, and the anchor pole is consistent with the axis of jack.
The utility model has the beneficial effects that compared with prior art, the utility model structure is simple, convenient test is installed,
The angle that wedge block is mainly used for adjusting between slope surface and anchor pole axis is subtracted with guaranteeing that axis is overlapped with anchor pole axis
Because of measurement error caused by deflecting in few anchor pole loading procedure, overcoming existing measurement method cannot survey when anchor pole shifts
The shortcomings that amount；The measuring system only deflects in measurement in anchor pole, when non-displacement, because the distance measured is constant, actually stretches
Long amount is zero, effectively rejects the displacement generated by rotation, keeps measurement result more true and reliable, overcome existing measurement method compared with
The problem of big limitation.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.A kind of anchor pole drawing group experiment displacement measurement system, is constituted as shown in Figures 1 to 3, including tripod 1, three feet
It is fixed in side slope 13 on frame 1 by fixing bolt 2, wedge block 3 is bonded with the inclined-plane of side slope 13 and is set in tripod 1
Portion is disposed with backing plate 4, jack 5, jack piston 6, sleeve 7, anchor pole 8 and fixes sleeve 9, fixing sleeve on wedge block 3
Lining rope 12 is provided between the top and fixing bolt 2 of cylinder 9.
Intermediate plate 11 is provided between the sleeve 7 and anchor pole 8.Intermediate plate 11 is conical by its shape, and pulling force is bigger, mentions to anchor pole 8
The bond stress of confession is bigger.
Fixed screw 10 is provided in the fixes sleeve 9.
The tripod 1 is equilateral triangle frame.Tripod 1 is equilateral triangle frame, convenient for coordinates computed point, between points
Distance.
The anchor pole 8 is consistent with the axis of jack 5.In order to guarantee the accuracy of measurement, displacement measurement errors are reduced.
Working principle of the utility model is:
The utility model relates to a kind of anchor rod drawings to test displacement measuring device, including tripod 1, pass through on tripod 1
Fixing bolt 2 is fixed in side slope 13, and wedge block 3 is bonded with the inclined-plane of side slope 13 and is set to the middle part of tripod 1, wedge block
Backing plate 4, jack 5, jack piston 6, sleeve 7, intermediate plate 11, anchor pole 8, fixes sleeve 9, fixed screw are disposed on 3
10 and lining rope 12.Its principle is that the length of 10 lining ropes 12 of fixing bolt is arrived by measurement fixes sleeve 9, calculates fixes sleeve 9
The coordinate at tip, to calculate 8 displacement of anchor pole.
Steps are as follows for its application method: installation fixed triangle frame 1, and measurement fixing bolt 2 arrives the distance of anchor pole 8, successively pads
Plate 4, jack 5, jack piston 6, sleeve 7, anchor pole 8 and fixes sleeve 9, between the top and fixing bolt 2 of fixes sleeve 9
It is provided with lining rope 12.It is adjusted when backing plate 4 is installed with wedge block 3, to guarantee that 8 axis of anchor pole is consistent with 5 axis of jack.
According to 12 length computation coordinate of lining rope and further calculates displacement the specific method is as follows:
Tripod 1 is equilateral triangle, side length 2a.Using the centroid of triangle as origin, wherein a line is x-axis, mistake
For origin perpendicular to the rectangular coordinate system that the axis of triangle projective planum is that z-axis is established, calculation formula is as follows:
By 1. -2.:
By 1.+2.:
By 1.+2.+3.:
5. and 6. in conjunction with:
It is obtained by Pythagorean theorem:
After tripod 1 is installed, before jack 5, the distance l that fixing bolt 2 arrives 8 exposure root of anchor pole is first measured10、
l20、l30, and the coordinate (x of the point is calculated accordingly0,y0,z0).During loading, measurement fixing bolt 2 arrives fixes sleeve 9
The distance l on top1、l2、l3, the coordinate (x, y, z) on vertex in loading procedure is calculated accordingly.Calculate point (x0,y0,z0) and point (x,
The distance between y, z), and and compare the variation of the distance to get the displacement of anchor pole 8 is arrived.
