Description
Technical field
The present invention relates to assembled architecture fields, and in particular to a kind of half grout sleeve 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.Reinforced bar sleeve grouting connection is common bar connecting form, sleeve in prefabricated concrete structure
It is in the milk and is connected as concealed work, the plumpness of strength cement-based grouting material directly influences prefabricated concrete structure in grout sleeve
Quality and safety.But may be because personnel's lack of skill, misoperation in work progress or lack a sense of responsibility, it leads
Spillage, running pulp phenomenon is caused to happen occasionally, the appearance of this phenomenon has seriously affected grouting quality, the case where " filling discontented " occurs,
Cause fatal constructional deficiency.Therefore, in grout sleeve the detection method of strength cement-based grouting material plumpness and find be in the milk
Benefit paste-making method when insufficient is building trade extensive concern and urgent problem to be solved.
The detection method of the plumpness of sleeve grouting at present is broadly divided into inside member exterior nondestructive determination and grout sleeve
The method of pre-buried sensor.Member exterior lossless detection method is mainly supercritical ultrasonics technology and Impact echo, due to reinforced bar sleeve
Connection structure replaces for multilayer dielectricity, and detection environment is complicated, and strength cement-based grouting material is very thin in radial thickness, and generally 5 ㎜~
6 ㎜ cause existing engineering lossless detection method that can not effectively detect it.Publication No. is in CN105223344A
State's patent document proposes a kind of device and method of pre-buried sensor detection reinforced bar sleeve grouting plumpness：By damping vibration
Sensor is embedded in the bottom of reinforced bar sleeve grout outlet, and sleeve grouting construction passes through detection after the completion or after grouting material solidification
Whether the attenuation of sensor signal wave amplitude comes whether discriminating sensor is coated by grouting material, full to detect grouting material.But
Being this method has the shortcomings that following three：(1) can only qualitative detection, the turgor of grouting material can not quantitatively be divided
Analysis brings difficulty for the result judgement in later stage；(2) damping vibration sensor must be installed in place before grouting construction, sensor
Once embedment sleeve cannot be reused, if to all sleeve whole placement sensors in engineering, the later stage carries out random
It takes a sample test, then testing cost is excessively high, each side is difficult to receive, if arranging a limited number of sensors at random before grouting construction,
Construction party learns test point in advance according to sensing station, will be directed to known test point well construction, finally lose with
The meaning of machine sampling observation, and still buried security risk.(3) in progress when plastering construction, wall part will must be stretched out
Sensor is cut off, 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 sleeve grouting not
It fills, can not also carry out in-situ repair, entire prefabricated components can only be replaced or pick to dig out by underproof grout sleeve to come again
It replaces new grout sleeve or is connected using reinforcement welding, then chiseled out with new concrete or strength cement-based grouting material to picking
Concrete is repaired.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.
Publication No. is that the Chinese patent literature of CN105865568A, CN106836657A propose a kind of bar connecting use
Repair apparatus when grout sleeve non-destructive ration examining device, grouting are insufficient and method, its essence is simply in grout sleeve
On to increase patching material input pipe, patching material output channel, detection liquid input tube road, detection liquid output pipe road total
Four newly-increased pipelines are counted, input liquid volume metrical instrument, output liquid volume measuring instrument and confession are then utilized when Site Detection
Water installations, will input the volume of liquid and the volume of output liquid makes the difference and obtains the liquid volume being trapped in grout sleeve, from
And judge sleeve inner grouting material plumpness situation, if grouting is not full, pass through patching material input channel using grouter
Patching material is injected into grout sleeve, and the detection liquid displacement that will be left in grout sleeve comes out, and needs in the repairing
The outlet of material output channel is sampled at times, until patching material output channel stablizes the close of the patching material of discharge
It spends and injects the density of patching material into grout sleeve and quite or when reaching setting density stop repairing.Above-mentioned apparatus and side
Method seems simple possible, there are in fact following disadvantage and can lead to the erroneous judgement of testing result：(1) to grout sleeve itself
For, four holes are added above slurry outlet for plugging four pipelines, the number of openings is excessively likely to result in grouting set
The decline of cylinder mechanical property, brings major safety risks.(2) for the prefabricated components manufacturing, that is added on sleeve is all kinds of
Pipeline is excessive, and original grout lines and pulp pipeline will have six roots of sensation pipeline in addition while centralized arrangement is in prefabricated components
Sleeve portion, if it is double sleeve, then number of tubes will also be double, this, which will undoubtedly vibrate to concreting, brings very greatly
Inconvenience, to influence production efficiency and component quality.(3) field detecting device is complicated, input liquid volume metrical instrument, defeated
It is cumbersome and inconvenient to carry to go out the device contexts assembly and adjustment such as liquid volume metrical instrument and water supply installation.(4) quantitative inspection
Survey method is not associated with engineering reality, and there may be large errors for testing result, be easy to cause erroneous judgement；The above method passes through delay
Liquid volume in grout sleeve judges that the turgor of grouting, this partially liq have not crossed slurry outlet and be full of sleeve
Cavity area in interior cavity area and pulp pipeline, since grouting material viscosity is larger, after the completion of grouting, grout outlet blocks
Tightly, even if stream of slurry in sleeve is empty, in the pulp pipeline of horizontal direction still can there are grouting materials, but in pulp pipeline
The final form of grouting material can not determine that the volume of i.e. cavity area in pulp pipeline is unknown, and the above method is directly used
The liquid volume in grout sleeve is trapped in measure the not turgor of grouting, does not consider remaining grouting in pulp pipeline
The volume metering error that material strip comes, it is easy to cause to judge by accident.(5) it is not selection when mending slurry will again to carry out after detection liquid extraction
Slurry is mended, but is gone out by patching material by liquid displacement is detected；When the above-mentioned repair apparatus of onsite application and method, material is repaired
The density that material output channel stablizes discharge patching material can not be detected fast and accurately, and the lasting benefit slurry of blindness be easy to cause filling
The waste of slurry increases cost.
