Description

A grouting sleeve grouting fullness detection device, detection system and detection method

technical field

The invention belongs to the technical field of prefabricated buildings, and in particular relates to a grouting sleeve fullness detection device, a detection system and a detection method.

Background technique

In recent years, with the vigorous development of prefabricated buildings, grouting sleeve connection, as the main connection method of prefabricated building steel members, has been increasingly used in the field of structural engineering. This method realizes the connection of steel bars by injecting grout into the sleeve connecting the steel bars at both ends. The fullness of grouting in the sleeve directly affects the structural connection strength. During the construction process, the grouting sleeve is not full due to improper operation, accidental grout leakage and other reasons, which greatly damages the safety of the building structure. Therefore, the detection of grouting fullness is of great significance to the quality assurance of prefabricated buildings at this stage.

At present, some scholars have proposed X-ray detection method, pre-embedded steel wire drawing method, air pressure detection method, etc. for the detection of grouting fullness of grouting sleeve. Among them, the X-ray detection method is difficult to be applied in engineering practice due to the complexity of the detection device, and X-ray itself is a kind of ionizing radiation that is highly harmful to the human body.

Pre-embedded steel wire drawing method, during the grouting process, place a steel wire on the sealing plug of the grout hole of the sleeve to be tested, wait for 3 days of grouting maintenance, and then perform a steel wire drawing test on the test sleeve. Use the puller to connect with the embedded steel wire and pull out the steel wire completely, record the ultimate pullout load value, and finally substitute the recorded data into the formula to judge whether the fullness of the sleeve grouting is qualified. Although the detection results of this method can provide an effective reference for judging the fullness of grouting, the defects of the detection method are as follows:

1. When the number of testing sleeves is large in the actual project, installing steel wires one by one for the sealing plug of the grouting hole of each sleeve to be tested will greatly increase the construction workload during the grouting process;

2. When performing steel wire drawing inspection, the steel wire drawing load must be kept continuous and uniform, and the drawing speed must be controlled at 0.15kN/s～0.50kN/s, which is difficult to operate;

3. The detection process needs to record the ultimate pulling load value, and the detection result judgment needs to substitute the recorded data into the formula to calculate whether the grouting fullness is qualified, and the detection process is cumbersome;

4. The detection sleeve needs to be maintained for 3 days after grouting, which is inefficient; and it can only be inspected once after the grouting material has finally set. If grouting is required after the inspection, it will be difficult to carry out subsequent inspections.

And air pressure detection method, as publication number is CN108801843A Chinese invention patent application discloses grouting sleeve grout compactness detection device and detection method thereof, this detection device comprises: sealing assembly, pressurization device, pressure vessel, pressure indicating gauge, the first A valve and a second valve. This patent is theoretically feasible in the detection of the grouting compactness performance of the grouting sleeve, but the defects of the detection method are as follows:

1. The detection process needs to record the pressure value of the pressure vessel every 30 minutes until the pressure value is stable or reaches 4 hours, the operation process is cumbersome and time-consuming;

2. The test results need to be calculated through formulas to judge the fullness of grouting, which is inefficient;

3. The air pressure value measured by the detection device is easily affected by the environment, and the detection error is relatively large.

The Chinese invention patent application with publication number CN107328921A discloses a device and method for detecting the fullness of grouting sleeve grouting material. The device includes a barometer, a hydraulic gauge, an automatic metering grouting pump, a pump connector and a control module. Although this device can detect the fullness of the grouting material after grouting to a certain extent, and find out the situation of inconsistency in time, the defects of the detection device are as follows:

1. High-precision instruments such as barometers, hydraulic gauges, automatic metering grouting pumps, and control modules are used, and the device cost is high;

2. Since the device uses a hydraulic gauge to detect the hydraulic pressure value of the grouting material, the invention can only detect the grouting material before the initial setting, and cannot detect the grouting material after the final setting;

3. The detection process needs to record the volume of the injected grout and the value of the hydraulic gauge after the grout is injected, and the operation process is cumbersome;

4. The detection results need to be calculated through complex calculation formulas, and the recorded data needs to be substituted many times to calculate the grouting fullness (grouting defect volume), which is inefficient.

Therefore, for the current field of prefabricated buildings, it is urgent to develop an efficient and reliable grouting sleeve grouting fullness detection device.

The method for detecting the grouting fullness of the grouting sleeve according to claim 8 or 9, characterized in that, in the sixth step, if the grouting defect volume of the grouting sleeve (71) measured is larger than that of the volume control air chamber (3 ) internal volume, the volume of the second volume area is greater than that of the first volume area, and after step 5 is completed, the pressure in the second volume area will be lower than the first volume area, so the position indicating piston (21) in the display tube (2) Affected by the air pressure difference between the two volume areas, it will deviate to the side of the second air pipe tee joint (52), that is, the position indicating piston (21) is biased to the side of the "×" symbol mark (26) on the display tube (2), that is, Indicates that the grouting fullness is unqualified; similarly, if the volume of the grouting defect in the grouting sleeve (71) is smaller than the internal volume of the volume control air chamber (3), after step five is completed, the position indicating piston (21) is biased toward the display tube (2) The "√" symbol marks one side of (24), which means that the grouting fullness is qualified.
