Description
Technical field
The present invention relates to Geotechnical Engineering field, is related specifically to a kind of measurement for expanding control anchoring-bolt broaching diameter
Method.
Background technology
At present, after engineering measures drilling and reaming in practice bore diameter method, mainly using sensing device and
The combination of signal processing system measures the diameter after pore-forming, and this method has complex operation and costly in practice in engineering
The shortcomings that, it is primarily used for measuring the diameter of final pore-forming, it is thus, using in actual applications and few, and this side
Method controls the measurement of the counter bore diameter of anchor pole to be less applicable for this expansion.
Many indefinite factors be present for the research of expansion control anchor pole, expansion controls the reaming under bolt action straight
The problems such as change in footpath, there is presently no measurement of the related scholar to the counter bore diameter to propose simple effective method.
Expansion control anchor pole makes termination reaming constantly increase under external force, the measurement to diameter after this pore-forming,
It is always the problem of numerous experts compare concern that can have a kind of operational and practical and cheap method, pin of the present invention
These problems are proposed with a kind of method that can measure expansion control anchoring-bolt broaching diameter.
A similar invention is retrieved in China State Intellectual Property Office patent consulting system：Measurement bore state is
The system and method for system and method, particularly check borehole final diameter（Application number 201180021262.0）.This method is main
Feature is to be used for check borehole final diameter, and using sensing device, measurement result precision is higher.Major defect is to cannot be used for surveying
The change of real-time diameter of the amount drilling during counter bore diameter, and operation is complex, utilizes remote measurement sensing device cost
It is higher, it is not suitable for measuring the counter bore diameter of this expansion control anchor pole in practice in engineering.
On November 18th, 2009, the GB Patent Application No. GB 2460096 as disclosed in Wajid et al. disclosed reaming
Device and the caliper tool with aperture measurement device.In the application, the instrument both has hole expansion function, and and can measurement is bored
Bore dia.Being still needs to utilize sensing device and professional expansion element, is not intended to this expansion control anchoring-bolt broaching diameter
Measurement.
At present, the phase of " method of measurement expansion control anchoring-bolt broaching diameter " is not inquired in SooPAT patent retrievals
Close patent；And paper, periodical and books without correlation etc. control measuring this expansion the counter bore diameter of anchor pole to propose row
Effective method.
The content of the invention
The object of the invention purpose is to provide a kind of measuring method for expanding control anchoring-bolt broaching diameter.Its purpose one is：
The change of reaming diameter in whole process of expansion can be measured using this method；Its purpose two is：Make up existing counter bore diameter
Weak point in method for measurement.
To achieve the above object, the technical scheme is that：
A kind of measuring method for expanding control anchoring-bolt broaching diameter, it is characterised in that：Methods described follows these steps to carry out：
1st, assembling device：Expansion gear is fitted into soil compaction device first, forms specific anchoring section, then by anchoring section and power transmission
Mechanism is connected, and expansion controlling organization is connected with gas tube, is finally connected force transmission mechanism with anchor slab, and fixed with nut；
2nd, the connection of line is measured：Graduated measurement line is marked into outer surface, along gas tube through soil compaction device in, and by swollen
The outside of swollen device, it measures the radian of line and is consistent with the steel disc radian on soil compaction device, and the end for measuring line is glued to
On the arc steel conduit welded on the inside of soil compaction the bottom of the device；
3rd, actual measurement：The expansion assembled control anchor pole is sent into tested hole, line surface smear lubricant will be measured, and
Through the space between soil compaction device and expansion gear, lead to outside anchor rod system, and tense measurement line, until there is no displacement
When, then measurement line is unclamped, the scale measured at hole on line is recorded, by expanding controlling organization through gas tube, to expansion gear
0.04-0.05Mpa is inflated to, stops inflation and waits 3-5 minutes, 0.05-0.1 Mpa/s speed is pressed after stable gas pressure, is continued
Expansion gear is inflated, during inflation, maximum pressure is no more than 5 Mpa；
4th, data record：During being inflated to expansion gear, measurement line can be with the expansion of air bag, and is gradually pulled in air bag
In, the scale on hole measurement line of 5 seconds records, the scale that line is measured by recording hole changes, so as to obtain
Reaming girth value added and perimeter change trend, using girth and the conversion relation of diameter, convert drilling diameter, draws bore dia
With time and the rule filled air pressure change and changed.
Compared with prior art, the positive effect of the present invention is：
1st, this method is closed expansion control anchor pole with the graduated measurement knot of surface mark and is used in conjunction with, and can measure reaming and entirely expand
The change of diameter during, without the use of complex appts such as the sensors in conventional method；
2nd, line being measured in this method to form by stock processing and fabricating of carbon fiber, this high telescopic variation of the strength of materials is small,
Have lubricant because carbon fiber self-strength is high and measures line surface smear, measure line will not break because air bag expands or
It is stuck between air bag and outside plate；
3rd, this method is without the use of the slide calliper rule in conventional method to measure final aperture, but with the scale on carbon fiber measurement line
Substitute slide calliper rule, by the relation of round girth and diameter, converse the variable quantity of counter bore diameter；
4th, not only simple possible cost is low for this method, can also measure the change of expansion control anchoring-bolt broaching diameter, make up to expansion
Control the deficiency of anchor pole research.
