Abstract
A kind of flat anchor rod drawing instrument, including flat hollow hydraulic jack, intermediate plate, oil pressure pump, petroleum pipeline, drawing backing plate, single hole anchor device, it is characterized in that, it is made up of piston, sealing ring, hollow plunger and cylinder body inside flat hollow hydraulic jack, at flat hollow hydraulic jack hollow space, single hole anchor device is installed, in single hole anchor device, the anchor pole to be tested according to different-diameter places matched intermediate plate, intermediate plate protrudes from flat hollow jack termination 0 10cm, to ensure to clamp anchor pole to be tested；Two oil transportation mouths of flat hollow hydraulic jack top side face are connected with oil pressure pump by petroleum pipeline；The base plate shear-face angle of hollow plunger is consistent with intermediate plate oblique angle.Flat anchor rod drawing instrument of the present utility model, can be good at solving, on conventional anchor Hubbing method, anchor pole is exposed deficiency, the problem causing cannot be carried out pull-out test, it has simple, economic, practical feature, to suppressing and stop to use inferior materials and turn out substandard goods to play an important role.
Description
Technical field
This utility model relates to during a kind of tunnel, colliery, foundation ditch or slope project reinforce, anchor bolt construction or quality testing
Flat anchor rod drawing instrument.
Background technology
Anchor pole tension pull out force is the important means of inspection anchor bolt construction quality.At present, existing anchor rod drawing is tested or executes
In work, it is desirable that and test anchor pole is reserved certain length, to ensure the enforcement of drawing.Length in reserve is too short or does not reserves, the most not
Possess test and execution conditions, it is impossible to carry out the drawing of anchor pole.The most just because of this, the random inspection of anchor bolt construction quality, just become
One empty verbiage.Overwhelming majority unit in charge of construction utilizes this drawback, would be required to anchor pole to be checked or the anchor cable of reserved detection length, carves
Meaning is higher than requiring that standard is constructed, and defective situation did not almost occur in testing result.The detection of anchor pole and construction, the most impossible
100% can reserve sufficient length, and therefore anchor bolt construction phenomenon of using inferior materials and turning out substandard goods is the most rampant.The construction quality of anchor pole, is to ensure tunnel
One of essential condition of road country rock and stability of slope.A kind of assay device of design, can be on the premise of without length in reserve, it is achieved with
Machine and representative sampling drawing detection are frights and stop the jerry necessary means of anchor bolt construction.
Summary of the invention
The purpose of this utility model is just to provide and a kind of the anchor pole that protruded length is too short can be carried out drawing and testing inspection
Flat anchor rod drawing instrument.
Flat anchor rod drawing instrument of the present utility model, including flat hollow hydraulic jack, intermediate plate, oil pressure pump, oil transportation
Pipe, drawing backing plate, single hole anchor device, it is characterised in that by piston, sealing ring, hollow plunger inside flat hollow hydraulic jack
Form with cylinder body, according to different-diameter in flat hollow hydraulic jack hollow space installs single hole anchor device, single hole anchor device
Anchor pole to be tested places matched intermediate plate, and intermediate plate protrudes from flat hollow jack termination 0-10cm, permissible to ensure
Clamp anchor pole to be tested；Two oil transportation mouths of flat hollow hydraulic jack top side face are connected with oil pressure pump by petroleum pipeline；In
The base plate shear-face angle of void column plug is consistent with intermediate plate oblique angle.
Flat anchor rod drawing instrument of the present utility model, if anchor pole to be measured is without protruded length, then needs along anchor pole periphery to be measured
Dig a bowl-shape test surfaces, dig out about 10cm and clamp anchor pole to be measured for intermediate plate.During test, by drawing backing plate pad country rock with
Between flat hollow hydraulic jack, then single hole anchor device is put in flat hollow hydraulic jack, intermediate plate is passed through single hole
Anchorage installation is on anchor pole to be tested, by with manually or electrically oil pressure pump jack, making intermediate plate be pressed from both sides by anchor pole to be tested
Tightly, continuing pressurization, can be shown by oil gauge, until pulling to design pulling capacity, simultaneously test drawing elongation, drawing is complete
Become, unclamp throttle.
Flat anchor rod drawing instrument of the present utility model, it is possible to well solve on conventional anchor Hubbing method outside to anchor pole
Dew deficiency, the problem causing cannot be carried out pull-out test, it has simple, economic, practical feature, to suppressing and stopping to slack off
Material reducing plays an important role.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
1, flat hollow hydraulic jack, 2, intermediate plate, 3, oil transportation mouth, 4, petroleum pipeline, 5, oil pressure pump, 6, oil gauge, 7, draw
Pull out backing plate, 8, anchor pole to be tested, 9, hollow plunger, 10, single hole anchor device, 11, sealing ring, 12, piston.
Detailed description of the invention
A kind of flat anchor rod drawing instrument, including flat hollow hydraulic jack 1, intermediate plate 2, oil pressure pump 5, petroleum pipeline 4, draws
Pull out backing plate 7, single hole anchor device 10, it is characterised in that flat hollow hydraulic jack 1 is internal by piston 12, sealing ring 11, hollow posts
Plug 9 and cylinder body composition, install single hole anchor device 10 at flat hollow hydraulic jack 1 hollow space, according to not in single hole anchor device 10
Placing matched intermediate plate 2 with the anchor pole to be tested 8 of diameter, intermediate plate 2 protrudes from flat hollow jack 1 termination 0-
10cm；Two oil transportation mouths 3 of flat hollow hydraulic jack 1 side are connected with oil pressure pump 5 by petroleum pipeline 4；Hollow plunger 9
Base plate shear-face angle consistent with intermediate plate 2 oblique angle.
