Description
Technical field
The present invention relates to assembled architecture fields, and in particular to a kind of slurry anchor connection part with detection hole and grouting are full
It spends detection method and mends paste-making method.
Background technology
Prefabricated assembled concrete structure has construction speed as a kind of structure type meeting industrialized production
Degree is fast, labor intensity is low, noise pollution and wet construction is few and the advantages such as product quality is easy to control, it has also become domestic and international construction industry
The main flow direction of development.
In assembled arthitecutral structure, especially in prefabricated concrete structure, component connection is to ensure that structure is whole
The key node of quality.It is the common bar connecting form in prefabricated concrete structure that reinforcing bar, which starches anchor overlap joint connection, starches anchor
It overlaps and is connected as concealed work, the plumpness of strength cement-based grouting material directly influences assembly concrete knot in slurry anchor connection part
The quality and safety of structure.But may be because personnel's lack of skill, misoperation in work progress or lack a sense of responsibility,
Spillage, running pulp phenomenon is caused to happen occasionally, the appearance of this phenomenon has seriously affected grouting quality, the feelings of " filling discontented " occurs
Condition causes fatal constructional deficiency.Therefore, it the detection method of strength cement-based grouting material plumpness and is being sent out in slurry anchor connection part
Benefit paste-making method when now grouting is insufficient is building trade extensive concern and urgent problem to be solved.
The detection method of the plumpness of slurry anchor connection part grouting at present is broadly divided into member exterior nondestructive determination and inside is pre-
The method for burying sensor.
Member exterior lossless detection method is mainly supercritical ultrasonics technology, Impact echo and x-ray method.Due to slurry anchor connection
Structure replaces for multilayer dielectricity, and detection environment is complicated, and strength cement-based grouting material is relatively thin in radial thickness, generally 10 ㎜~14
㎜, although supercritical ultrasonics technology and Impact echo to a certain extent it can be found that the uncompacted situation of grouting, to grout compartment and
The interface of non-grout compartment judges not accurate enough, can't be applied to engineering practice at present.X-ray method can more clearly judge
The interface of grout compartment and non-grout compartment inside single duct, but specimen thickness when its effective detection has apparent limitation.
It is more mature at present in internal pre-buried sensor method to be detected for pre-buried sensor DAMPED VIBRATION METHOD, it is grasped in grouting
Damping vibration sensor is embedded in the bottom of slurry outlet before making, in filling process and grouting material initial set advance row amplitude with
Energy value real-time testing judges whether sensor is coated by grouting material by checking the amplitude decay situation of sensor signal,
To determine whether grouting is full closely knit.But this method has the shortcomings that following three：(1) can only qualitative detection, can not to grouting
The turgor of material carries out quantitative analysis, and difficulty is brought for the result judgement in later stage；(2) damping vibration sensor must fill
It is installed in place before slurry construction, sensor is once embedded to and cannot reuse, if complete to all slurry anchor connection parts in engineering
Portion's placement sensor, later stage are taken a sample test at random, then testing cost is excessively high, each side is difficult to receive, if before grouting construction
It arranges that a limited number of sensors, construction party learn test point in advance according to sensing station at random, will be directed to known
Test point well construction finally loses the meaning inspected by random samples at random, and has still buried security risk.(3) it is painted in progress
When construction, the sensor for stretching out wall part must be cut off, it is time-consuming and laborious to ensure the planarization of wall.
In addition, when both the above detection method carries out late detection after grouting material solidification, even if finding slurry anchor connection part
Grouting is not filled, can not also be carried out in-situ repair, can only be replaced entire prefabricated components or underproof slurry anchor connection part is picked chisel
Out reinforcement welding is used to connect, is then repaired with new concrete or strength cement-based grouting material to picking the concrete chiseled out.
This method for repairing and mending can not only result in waste of resources, and can also influence the progress of next process, cause construction delay.

Row, there are in fact following disadvantage and can lead to the erroneous judgement of testing result：(1) originally to grout sleeve (or slurry anchor connection part)
For body, four holes are added above slurry outlet for plugging four pipelines, the number of openings is excessively likely to result in grouting
The decline of sleeve (or slurry anchor connection part) mechanical property, brings major safety risks.(2) for the prefabricated components manufacturing,
The various pipes added on sleeve (or slurry anchor connection part) are excessive, and original grout lines and pulp pipeline will have the six roots of sensation in addition
Pipeline sleeve (or the slurry anchor connection part) position of centralized arrangement in prefabricated components simultaneously, if it is double sleeve (or double slurry
Anchor connector) then number of tubes will also be double, and this, which will undoubtedly vibrate to concreting, brings very big inconvenience, to influence
Production efficiency and component quality.(3) field detecting device is complicated, input liquid volume metrical instrument, output liquid volume metering
The device contexts assembly and adjustment such as instrument and water supply installation is cumbersome and inconvenient to carry.(4) quantitative detecting method is not associated with work
Cheng Shiji, there may be large errors for testing result, be easy to cause erroneous judgement；The above method by be trapped in grout sleeve (or slurry
Anchor connector) in liquid volume come judge grouting turgor, this partially liq do not crossed slurry outlet and be full of sleeve
The cavity area in cavity area and pulp pipeline in (or slurry anchor connection part) has been in the milk since grouting material viscosity is larger
Cheng Hou, grout outlet block tightly, even if the stream of slurry in sleeve (or slurry anchor connection part) is empty, in the pulp pipeline of horizontal direction
Still can there are grouting materials, but the final form of grouting material can not determine in pulp pipeline, i.e. cavity in pulp pipeline
The volume in region is unknown, and the above method is directly measured with the liquid volume being trapped in grout sleeve (or slurry anchor connection part)
The not turgor of grouting, does not consider the volume metering error that remaining grouting material is brought in pulp pipeline, it is easy to cause to miss
Sentence.(5) instead of selection will not carry out benefit slurry again after detection liquid extraction when mending slurry, be set by patching material by liquid is detected
It swaps out；When the above-mentioned repair apparatus of onsite application and method, patching material output channel stablize discharge patching material density without
Method fast and accurately detects, and the lasting benefit slurry of blindness be easy to cause the waste of grouting material, increases cost.
