Description
Technical field
The present invention relates to assembled architecture fields, and in particular to a kind of method of batch detection grout sleeve compactness.
Background technique
Term is explained:
Box counting dimension: assuming that vibration wave signal s ∈ F, F that grout sleeve excited vibration generates are n dimension theorem in Euclid space RnAbove
Closed set.By RnIt is divided into the square grid that width as small as possible is δ, if NδBe mesh width be δ it is discrete
Spatially covering F gathers least the number of grids, we are by vibration wave s box counting dimension is defined as:
With the fast development of China's economy and urbanization, building industrialization process is also being accelerated, the cast-in-place building skill of tradition
Art has been unable to meet and sends out in building trade since resource distribution is unreasonable, mechanization of building operation degree is low, construction operation environment is poor
Exhibition demand.Assembled architecture quick, energy conservation and environmental protection, the guaranteed standard of quality as a kind of high construction efficiency developed in recent years
Change green building form, receives the attention of building trade, and obtained countries and regions building trade relevant ministries and commissions energetically
It supports to promote.
The shock resistance and integrality of assembled architecture are to restrict the important factor in order of its development, to improve assembled architecture
Shock resistance and integrality, must ensure that there is reliable connection between assembled architecture component.Common assembled architecture connection
Mode mainly realizes by using grout sleeve and connects that the integrality of assembled architecture is effectively guaranteed in the connection type,
Therefore the shock resistance for also having correspondingly improved assembled architecture, is widely used in room and builds fabricated shear wall, bridge assembled box beam
And in the building structure such as Bridge Pier.
Grout sleeve is mainly made of connection reinforcing bar with sleeve.Currently, the detection of conventional grout sleeve compaction rate
Method is to grout sleeve joint test piece using simple tension, high stress tensile compression test, large deformation tensile compression test etc. repeatedly repeatedly
Method；On lossless detection method, a system such as supercritical ultrasonics technology, Impact echo, infrared thermography and X-ray industry CT method
Column method, although the information of grout sleeve compaction rate can be accessed to a certain extent；But these methods are to batch
It is not only time-consuming and laborious when grout sleeve is detected, and the testing equipment of these methods all excessively bulky complex mostly, detection
Instrument cost is high, at the same there are also Part Methods there is also ray radiation and environmental pollutions the problems such as, if staff's long-time
To in such a case, can largely cause harm to the human body；Therefore there presently does not exist one kind can efficiently in batches
Detect the detection method of grout sleeve compactness.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of method of batch detection grout sleeve compactness,
To improve the efficiency of batch detection grout sleeve compactness.
The technical solution adopted by the present invention to solve the technical problems is: a kind of side of batch detection grout sleeve compactness
Method, including grout sleeve, the upper and lower ends of the grout sleeve are embedded with reinforcing bar respectively, and the reinforcing bar of the upper and lower ends passes through grouting
The concrete of sleeve inner is fixed；The grout sleeve is equipped with grout outlet and grouting mouth；
The method of the batch grout sleeve compactness inspection is carried out as follows:
Step 1, vibrating sensor is set in the grouting mouth of grout sleeve to be detected, and the vibrating sensor connects data
Acquire equipment；The data acquisition equipment connects computer；
Step 2, log-on data acquisition equipment, vibrating sensor and computer, and make the pulp of grout sleeve to be detected
Mouth generates exciting wave, then acquires the feedback waveform of grout sleeve to be detected；
Step 3, step 1 and step 2 are repeated, remaining grout sleeve is detected；
Step 4, calculate the box counting dimension of each grout sleeve feedback waveform with MATLAB software, and round off retain to
Then one decimal place calculates the box counting dimension average value of each grout sleeve feedback waveform again；
Step 5, the box counting dimension of each grout sleeve feedback waveform is individually subtracted with the box counting dimension average value in step 4, so
Absolute value processing is done to obtained difference afterwards；Finally the size of root absolute value covers each grouting by sequence from big to small again
Cylinder is ranked up；
Step 6, it to the grout sleeve after sequence is sequenced by step 5, is finely detected one by one in order, described is fine
Detection can be accurately obtained grout sleeve compaction rate；
Step 7, during finely being detected one by one in order to each grout sleeve, if being consecutively detected three
A grout sleeve is closely knit grout sleeve, then stops fine detection, and detected leakiness grout sleeve is this batch
Whole uncompacted grout sleeves, remaining all closely knit grout sleeve in grout sleeve.
As an improvement of the above scheme, described to be finely detected as X-ray industry CT method.
Further, the exciting wave is generated by super mangneto focus, and the super mangneto focus is fixed on the pulp of grout sleeve
Mouthful；The super mangneto focus can produce the waveform of different vibration frequencies, and the waveform is controllable；Or the exciting wave is by exciting
Hammer to grout outlet tapped and generated or.
Further, in step 1, couplant is coated on the contact surface of the vibrating sensor and grout sleeve.
Further, the couplant is butter.
The beneficial effects of the present invention are: calculating the box counting dimension that each grout sleeve exciting feeds back waveform by MATLAB, so
Afterwards by the analysis of box counting dimension, detection sequence is carried out to each grout sleeve, finally according still further to sequence one by one to grout sleeve into
Row detection, until continuously detecting three qualified grout sleeves；By this detection method to batch grout sleeve compactness
It is detected, staff is just not necessarily to finely detect whole grout sleeves, to greatly improve testing staff
Detection efficiency, finally effectively reduce operating time of the staff in the case where there is radiation environment；And testing result is compared with it
His detection method more have convincingness, more precisely, it is reliable.
