Description
Technical field
The present invention relates to Geotechnical Engineering fields, are related specifically to a kind of measurement of expansion control anchoring-bolt broaching diameter
Method.
Background technique
Currently, 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 exists complicated for operation and costly in practice in engineering
The shortcomings that, it is primarily used for measuring the diameter of final pore-forming, thus, it is using in practical applications and few, and this side
Method is less applicable in for the measurement of the counter bore diameter of this expansion control anchor pole.
For the research for controlling anchor pole is expanded there are many indefinite factors, the reaming that expansion controls under bolt action is straight
The problems such as variation of diameter, there is presently no related scholars to propose simple effective method to the measurement of the counter bore diameter.
Expansion control anchor pole increases end reaming constantly under external force, the measurement to diameter after this pore-forming,
There can be a kind of operability and practical and cheap method is always the problem of numerous experts compare concern, needle of the present invention
A kind of method that can measure expansion control anchoring-bolt broaching diameter is proposed to these problems.
A similar invention is retrieved in China State Intellectual Property Office patent consulting system: measure bore state is
The system and method (application number 201180021262.0) of system and method, especially check borehole final diameter.This method is main
Feature is for check borehole final diameter, and using sensing device, measurement result precision is higher.Major defect is to cannot be used for surveying
The variation of real-time diameter of amount drilling during counter bore diameter, and complicated operation, utilizes telemetering 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 caliper tool with aperture measurement device.In the application, the tool not only has hole expansion function, but also is capable of measuring brill
Bore dia.It is still and needs to be not intended to this expansion control anchoring-bolt broaching diameter using sensing device and professional expansion element
Measurement.
Currently, not inquiring the phase of " method of measurement expansion control anchoring-bolt broaching diameter " in SooPAT patent retrieval
Close patent；And row is proposed to the counter bore diameter for measuring this expansion control anchor pole without relevant paper, periodical and books etc.
Effective method.
Summary of the invention
The object of the invention is designed to provide a kind of measurement method of expansion control anchoring-bolt broaching diameter.Its purpose one are as follows:
The variation of reaming diameter in entire process of expansion is capable of measuring using this method；Its purpose two are as follows: make up existing counter bore diameter
Shortcoming in method for measurement.
To achieve the above object, the technical solution of the present invention is as follows:
A kind of measurement method of expansion control anchoring-bolt broaching diameter, it is characterised in that: the method follows these steps to carry out:
1, expansion device: being fitted into soil compaction device by assembling device first, forms specific anchoring section, then by anchoring section with
Force transmission mechanism is connected, and expansion control mechanism is connected with gas tube, finally connect force transmission mechanism with anchor slab, and solid with nut
It is fixed；
2, it measures the connection of line: graduated measurement line is marked into outer surface, along gas tube through in soil compaction device, and lead to
The outside of expansion device is crossed, the radian of measurement line is consistent with the steel disc radian on soil compaction device, measures the end glue of line
It connects on the arc steel conduit welded on the inside of soil compaction the bottom of the device；
3, actual measurement: assembled expansion control anchor pole is sent into tested hole, and lubrication is smeared on measurement line surface
Agent, and through the gap between soil compaction device and expansion device, it leads to outside anchor rod system, and tense measurement line, until there is no position
When moving generation, measurement line is unclamped again, records the scale measured on line at hole, by expansion control mechanism through gas tube, to swollen
Swollen device is inflated to 0.04-0.05Mpa, stops inflation and waits 3-5 minutes, the speed of 0.05-0.1 Mpa/s is pressed after stable gas pressure
Rate continues to inflate expansion device, and when inflation, maximum pressure is no more than 5 Mpa；
4, data record: during inflating to expansion device, measurement line can gradually be pulled in the expansion of air bag
In air bag, the scale on line is measured every hole of 5 seconds records, is changed by the scale that record hole measures line, thus
Reaming perimeter value added and perimeter change trend are obtained, using the conversion relation of perimeter and diameter, convert drilling diameter, must portal
Diameter at any time and fills air pressure change and the rule that changes.
Compared with prior art, the positive effect of the present invention are as follows:
1, this method is marked graduated measurement knot conjunction expansion control anchor pole with surface and is used in conjunction with, and is capable of measuring reaming whole
The variation of diameter in a process of expansion, without the use of complex appts such as sensors in conventional method；
2, it measures line in this method to form by basic material processing and fabricating of carbon fiber, this high telescopic variation of the strength of materials
It is small, it is coated with lubricant since carbon fiber self-strength is high and measures line surface, measuring line will not break because air bag expands
Or it is stuck between air bag and outside plate；
3, this method measures final aperture without the use of the slide calliper rule in conventional method, but on carbon fiber measurement line
Scale replaces slide calliper rule to converse the variable quantity of counter bore diameter by the relationship of round perimeter and diameter；
4, not only simple possible is at low cost for this method, can also measure the variation of expansion control anchoring-bolt broaching diameter, make up pair
The deficiency of expansion control anchor pole research.
