Description

Technical Field

[0001] The present invention relates to the technical field of shield construction, and in particular to a construction quality control device, a rapid detection device and a method for a segment waterproof sealing pad. Background Art

[0002] Pipe segment waterproofing materials are generally pasted with single-component adhesives. After the adhesive is applied, it needs to cure for 5 to 10 minutes before the waterproofing material is pasted, and then the sealing gasket is manually knocked to make it firmly adhered. However, the curing time of the adhesive will change due to the influence of season, temperature, etc., and improper pasting timing will affect the bonding effect. In addition, the construction personnel of waterproofing materials on the construction site are highly mobile, and the waterproofing construction operation is highly subjective. It is often difficult to accurately grasp the timing of pasting waterproof materials, and the quality of waterproofing construction is often uneven. The current specifications only stipulate the bonding strength of waterproof adhesives, and lack on-site construction control standards and rapid detection methods for waterproofing materials, which makes it difficult to control the construction quality of waterproofing materials. If the quality of waterproofing construction is poor, the pipe segments are prone to falling off during assembly, and accumulation occurs at the corners, which can easily lead to leakage in the pipe segment joints, affecting the durability of the tunnel.

[0003] The search found:

[0004] The Chinese invention patent application publication number CN115165673A discloses a test device and a test method capable of testing the viscosity of an adhesive, and the implementation steps thereof include: step one, applying the adhesive to be tested on the test area on the upper surface of the test substrate; step two, manually pressing the limit block so that the first return spring is compressed, the push-pull column slides toward the position close to the test ball placement assembly, and the driving connecting rod is pushed by the push-pull column to rotate, so that the movable half ring rotates, and the distance between the lower ends of the fixed half ring and the movable half ring is widened, so that the test ball slides downward along the upper surface of the test substrate; step three, based on step two, the test ball slides downward along the upper surface of the test substrate to the adhesive to be tested on the test area, and at the same time, the photoelectric sensor switch detects and senses the test ball; step four, based on step three, the photoelectric sensor switch senses the test ball. The electric sensor switch senses the test ball and transmits a switch signal to control the timer to start timing; step five, based on step four, when the photoelectric sensor switch senses the test ball, the start timer starts timing, and when the photoelectric sensor switch cannot sense the test ball, the stop timer stops timing; step six, based on step five, the time that the test ball is retained on the test area due to the viscosity of the adhesive being tested is measured, and the viscosity between different adhesives being tested is determined by different retention times. However, this patent still has the following problems: 1) There is no measure to control the thickness of the glue, and it is difficult to consider the effect of the glue thickness on the adhesion; 2) The effect of the glue curing time is not considered, and adhesion tests at different times cannot be carried out; 3) The effect of different temperatures on adhesion is not considered, and the test results are affected by temperature differences.

[0005] The Chinese invention patent application publication number CN112461750A discloses a device for testing the initial adhesion performance of an adhesive and a method for testing the initial adhesion performance of an adhesive, which is used to test the initial adhesion performance of an adhesive, comprising: a base; a first clamping mechanism, comprising a substrate clamp and a lifting unit, wherein the substrate clamp is fixed at the lifting unit, and the substrate clamp is fixed to clamp the first substrate and can be lifted and lowered at a specified speed along the longitudinal direction of the base by the lifting unit; a second clamping mechanism, comprising a test plate and a translation unit connected to each other, wherein the test plate is clamped to clamp the second substrate and can be translated along a transverse direction orthogonal to the longitudinal direction by the translation unit, wherein a plurality of transverse directions are provided on the test plate. The test points are arranged in parallel and at intervals, and the second substrate forms test surfaces that are bonded to the first substrate through the test points; wherein, the first clamping mechanism also includes a pressure unit, which is arranged on the upper part of the substrate clamp and applies a specified pressure when the test surfaces of the first substrate and the second substrate are bonded to each other; and a testing mechanism. This patent can repeatedly test the initial adhesion of the adhesive under different temperatures, pressures and different bonding times. However, this patent still has the following problems: 1) There is no measure to control the thickness of the brushed glue, and it is difficult to consider the influence of the brushed glue thickness on the adhesion; 2) For flexible materials such as sealing gaskets, the clamping may cause deformation, affecting the adhesion test results.

DETAILED DESCRIPTION

[0060] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several variations and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0061] Reference Figure 1 , is a structural diagram of a device for controlling the construction quality of a pipe segment waterproof sealing pad provided by an embodiment of the present invention, combined with Figure 2-4The device includes an inclined panel 7, a leg mechanism, a glue coating plate 8, a heating device 9, a temperature measuring device 10, a sealing gasket fixing device 17, a ball chute base 4, multiple sets of ball chutes 1, a baffle and a controller 3, wherein: the inclined panel 7 serves as the operating platform of the device, and a lower panel 13 is provided below the inclined panel 7. Specifically, a glue brushing area is provided in the middle of the inclined panel 7, and the glue brushing area is a concave structure on the inclined panel 7. The lower panel 13 is located below the glue brushing area. The inclined panel 7 is connected to the lower panel 13 to form an integral structure to increase the inclined panel. The overall strength of the panel 7; the leg mechanism is located below one end of the inclined panel 7, so that the inclined panel 7 is in an inclined state; the glue-coating plate 8 is located on the glue-brushing area of ​​the inclined panel 7, and the temperature measuring device 10 is provided on the surface of the glue-coating plate 8 for real-time monitoring of the temperature of the glue-coating plate 8; the sealing gasket fixing device 17 is provided on the inclined panel 7, and the sealing gasket fixing device 17 is used to fix the waterproof sealing gasket 16 (i.e., sealing gasket) between the inclined panel 7 and the sealing gasket fixing device 17; the glue-coating plate 8 and the sealing gasket fixing device 17 are respectively located on the glue-brushing area of ​​the inclined panel 7, and the glue-coating plate 8 and the sealing gasket fixing device 17 correspond to two different test conditions, which are selected for use according to different test conditions. When the sealing gasket fixing device 17 is used, the height difference between the waterproof sealing gasket 16 and the surface of the inclined panel 7 is the glue-brushing control thickness; a height adjusting device 15 is provided below the glue-brushing area, and the height adjusting device 15 is used to adjust the height of the glue-coating plate 8 or the sealing gasket fixing device 17 to achieve the adjustment of the glue-brushing thickness; a heating device 9 is provided below the glue-brushing area for heating the glue-coating plate 8 or the sealing gasket fixing device 1 7; a ball chute base 4 is located on the upper surface of one end of the inclined plate 7; multiple sets of ball chutes 1 are located on the upper surface of the ball chute base 4. The ball chutes 1 are structures opened on the surface of the ball chute base 4 and are used to release the balls at different time points; a baffle 2 is used to fix the balls in their initial position; a controller 3 is used to control the falling time of the balls to test the rolling distance of the balls on the rubber-coated plate 8 at different times. The controller 3 can independently control the baffle 2 of each ball chute 1 to cause the balls to fall at different times. The balls fall from a height and are accelerated by the ball chute 1 to ensure that the balls move parallel to the sliding direction. The adhesive decelerates the balls as they pass through the rubber-coated plate 8. The adhesive performance of the adhesive can be measured by measuring the sliding distance.

[0062] In the above embodiment, by setting up multiple groups of ball chutes 1, balls of the same specification can be launched at different time points, the adhesive adhesion effect can be judged by the rolling distance of the balls, the quality of the adhesive can be quickly tested by the constant temperature test, and the optimal curing time of the adhesive can be determined by the same conditions test at the work site, providing guidance for the on-site construction of waterproof materials.

[0063] In the above embodiment, the adhesive coating plate 8 and the gasket fixture 17 correspond to two different test conditions. The operation using the adhesive coating plate 8 is relatively simple, allowing for rapid execution of multiple tests to quickly test the adhesive's adhesion. The gasket fixture 17 (corresponding to the gasket condition) is primarily used to simulate the actual surface adhesion of the gasket during application, thereby providing guidance for on-site gasket application.

[0064] In some embodiments, the balls are cast by concrete, which can better reflect the bonding strength between the adhesive and the concrete interface and is more in line with actual working conditions.

[0065] In some embodiments, the position of the ball chute 1 is adjustable. Specifically, a chute positioning device 11 is provided at one end of the inclined plate 7. The chute positioning device 11 fixes the ball chute 1 at different heights, thereby changing the rolling distance of the ball. Preferably, the chute positioning device 11 uses positioning bolts, which are spaced from the end of the inclined plate 7. By tightening the positioning bolts at different positions, the ball chute 1 is fixed at the corresponding position height. Since the position of the ball on the ball chute base 4 is fixed, adjusting the position of the ball chute base 4 can change the potential energy of the ball's descent, thereby changing the rolling distance of the ball.

[0066] In some embodiments, the leg mechanism includes a leg 5 and an adjustable pier 6, one end of the leg 5 is fixedly connected to the inclined panel 7, and the other end of the leg 5 is threadedly connected to the adjustable pier 6. By rotating the adjustable pier 6, the overall height of the leg mechanism can be adjusted to change the potential energy of the ball; at the same time, the heights of both sides of the inclined panel 7 can be ensured to be consistent to prevent the ball from sliding down during the rolling process.

[0067] In some embodiments, the glue plate 8 can be replaced to quickly carry out multiple sets of tests. Figure 2-3 , the glue-coating plate 8 is lower than the inclined panel 7, and a groove 14 is formed between the glue-coating plate 8 and the inclined panel 7. The plane size of the glue-coating plate 8 is the same as the plane size of the groove 14. The groove 14 serves as a control structure for the thickness of the adhesive coating. The height adjustment device 15 is a circle of bolts arranged below the glue-coating plate 8. The glue-coating plate 8 is a movable plate. By adjusting the height of the glue-coating plate 8 by the bolts, the thickness of the groove 14 can be adjusted, thereby facilitating the control of the glue thickness. The height difference between the glue-coating plate 8 and the inclined panel 7 is the height of the groove 14, which is also the glue thickness control value. After the glue is applied, the glue is scraped flat with a scraper, and the final glue surface height is level with the inclined panel 7. The heating device 9 is a heating tube arranged at the bottom of the glue-coating plate 8, which heats the glue-coating plate 8 through the heating tube. The temperature measuring device 10 adopts a temperature sensor, which uses the temperature sensor to monitor the temperature of the glue-coating plate 8 in real time. The heating device 9 adjusts the heating power according to the monitored temperature to keep the glue-coating plate 8 at a preset temperature.

[0068] In some embodiments, the heating device 9 is provided with an insulation device 12 at the positions in contact with the glue-coated plate 8 and the inclined plate 7 respectively. The insulation device 12 is used to heat the glue-coated plate 8 using the intermediate air, and the insulation device 12 ensures that the glue-coated plate 8 is heated evenly.

[0069] In some embodiments, the sealing gasket fixing device 17 is a rectangular structure. According to the size of the upper structure of the sealing gasket, the sealing gasket fixing device 17 is provided with a slot at the corresponding position, and the sealing gasket is placed in the slot. A top counterweight is provided above the sealing gasket fixing device 17. After the waterproof sealing gasket 16 is installed on the sealing gasket fixing device 17, the top counterweight is squeezed to make the glue surface of the waterproof sealing gasket 1 smooth. The sealing gasket fixing device 17 is customized according to the size of the sealing gasket and can fix the sealing gasket in reverse. Figure 4 As shown, the height of the sealing gasket fixing device 17 is adjusted by the height adjusting device 15 to adjust the thickness of the brushed glue.

[0070] In some implementations, the controller 3 adopts a PLC controller. Of course, in other implementations, other types of controllers may also be adopted, and the embodiment of the present invention does not specifically limit this.

[0071] Another embodiment of the present invention provides a method for controlling the construction quality of a pipe segment waterproof sealing gasket, which is implemented using the above-mentioned pipe segment waterproof sealing gasket construction quality control device. The method includes:

[0072] S1, using the heating device 9 to make the temperature of the glue-coated plate 8 reach the standard temperature (25°C); those skilled in the art will understand that in this step, it is necessary to first adjust the position of the ball chute 1 and the height of the leg mechanism to level the entire frame, that is, the heights of both sides of the inclined plate 7 are consistent, and clean the ball chute 1 and the glue-coated plate 8 to facilitate the test;

[0073] S2, applying a preset thickness of adhesive on the coating plate 8 and smoothing it with a scraper to ensure a uniform coating thickness; in this step, the coating plate 8 is positioned by adjusting the height adjustment device 15 to control the coating thickness;

[0074] S3, placing the ball at the initial position, fixing it with baffle 2, and setting the ball falling time with controller 3;

[0075] S4, measuring the rolling distance of the ball on the adhesive plate 8 at different times, and by changing the thickness of the adhesive, obtaining the bonding performance of adhesives of different thicknesses at different times, and plotting the bonding force curve of the adhesive under standard test conditions; measuring the rolling distance of the ball on the adhesive plate at different times, and using the rolling distance to represent the bonding effect of the adhesive;

[0076] This step conducts an indoor standard test. Through a large number of repeated tests, the adhesion performance curve of the sealant is preliminarily obtained to provide a reference for the thickness of the sealant glue. Specifically, by adjusting the height of the glue-coating plate 8, the thickness of the groove 14 (i.e., the glue coating thickness) is adjusted, and the test is repeated. Through multiple tests, the adhesion performance of adhesives of different thicknesses at different times can be obtained, and the adhesion force curve of the adhesive under the test conditions can be drawn. At the same time, after determining the performance parameters, as a reference for subsequent sealant quality control, the performance of the glue is quickly tested on materials entering the site from different batches. Thus, different batches of adhesives can be tested, the adhesion performance of the adhesives can be analyzed, and adhesives with abnormalities can be further inspected.

[0077] S5, placing the waterproof sealing gasket 16 on the sealing gasket fixing device 17, and making the sealing gasket brushing surface flat by using the top counterweight;

[0078] This step conducts a field test under the same conditions, testing the gasket's adhesive properties under actual on-site construction conditions. The thickness range for this set of adhesive is roughly determined based on the curve obtained during the aforementioned standard test. This step primarily considers factors such as temperature, thickness, and setting time to determine the actual on-site construction control indicators.

[0079] S6, place the sealing gasket fixing device 17 on the glue brushing area. The height difference between the sealing gasket and the inclined plate 7 is the glue brushing control thickness (i.e., glue brushing thickness), which is determined according to the bonding force curve under the standard test conditions. Adjust the height adjustment device 15 to make the sealing gasket glue brushing surface flat;

[0080] S7, placing the entire device in the waterproof material construction area and leaving it to stand until the device test temperature is close to the actual temperature;

[0081] It should be noted that the current construction plan is generally to let it stand for 24 hours after pasting. This value is the minimum value for on-site control. The longer the standing time, the more conducive the glue will be to solidifying, which can improve the bonding quality for a certain period of time. However, due to site limitations, if the storage time is too long, additional construction sites will be required. Therefore, the appropriate standing time can be determined according to the specific situation.

[0082] S8, placing the ball at the initial position, fixing it with the baffle 2, and setting the ball falling time with the controller 3;

[0083] S9, test the rolling distance of the ball at different times to obtain the relationship between the adhesive on the surface of the sealing gasket and time, so as to determine the optimal glue brushing thickness and curing time under the construction conditions.

[0084] The above step S4 performs a constant temperature standard test and obtains the corresponding standard value; step S9 continues to perform the same condition test and obtains the corresponding control value. Specifically, in step S9, the height difference between the sealing gasket fixing device 17 and the waterproof sealing gasket 16 is changed to control the thickness of the glue brushing, and 10 to 14 are repeated to test the rolling distance of the ball at different times. Through multiple groups of experiments, the relationship between the adhesive on the surface of the sealing gasket and time is studied to determine the optimal glue brushing thickness and curing time under the construction conditions, providing guidance for the on-site waterproof material construction. It is also possible to re-conduct the adhesive quality and bonding test (i.e., the above-mentioned pipe segment waterproof sealing gasket construction quality control method) according to the changes in the on-site construction conditions to guide the actual construction.

[0085] Another embodiment of the present invention further provides a device for quickly detecting the construction quality of a pipe segment waterproof sealing gasket, the device comprising a detection mechanism and the above-mentioned pipe segment waterproof sealing gasket construction quality control device, Figure 5-6 , wherein: the pipe segment waterproof sealing gasket construction quality control device is used to determine the optimal glue brushing thickness and curing time under construction conditions, and the waterproof sealing gasket 16 is pasted on the pipe segment body 22 according to the optimal glue brushing thickness and curing time determined by the pipe segment waterproof sealing gasket construction quality control device; the detection mechanism includes a panel 18, a lower tray 20 and a vertical rod 19, the panel 18 is sleeved on the waterproof sealing gasket 16, and the panel 18 is fixedly connected to the waterproof sealing gasket 16 by fastening bolts 24, so that the detection device is suspended and fixed on the waterproof sealing gasket 16; the lower tray 20 is arranged below the panel 18 and is used to place a counterweight block 21; the vertical rod 19 is used to connect the lower tray 20 and the panel 18.

[0086] In some preferred embodiments, the centerline of the vertical rod 19 coincides with the fastening bolt 24 to improve the stability of the device's fixation. An adjustable leg 23 is provided between the segment annulus and the vertical rod. The adjustable leg 23 is perpendicular to the vertical rod 19. The entire detection device is rigidly connected, and the adjustable leg 23 is rigidly connected to the vertical rod 19. After the detection mechanism is fixed, the adjustable screw at the end of the adjustable leg 23 near the vertical rod 19 is adjusted to make the adjustable leg 23 contact the segment annulus. Since the overall height difference of existing shield tunnel segment sealing gaskets is small (no more than 1 cm), the requirements can be met by slightly changing the telescopic length of the adjustable leg 23, thereby supporting the adjustable leg 23 on the segment and preventing the entire device from overturning.

[0087] In the prior art, sealing gaskets are tested after application, as long as they do not fall off during transportation. The device for rapidly testing the construction quality of segment waterproof sealing gaskets in the above embodiment tests the adhesive properties of waterproof sealing gaskets by changing the counterweight 21, enabling rapid testing of the gasket's adhesive properties. Compared to the prior art, this device can effectively control the construction quality of waterproof materials.

[0088] Another embodiment of the present invention further provides a method for quickly detecting the construction quality of a pipe segment waterproof sealing gasket, which is used to detect the construction quality (i.e., the pasting quality) of the waterproof sealing gasket, and is implemented using the above-mentioned device for quickly detecting the construction quality of a pipe segment waterproof sealing gasket. The method includes:

[0089] S1, according to the optimal glue thickness and curing time under the construction conditions, affix the waterproof sealing gasket 16 to the segment body 22 and let it stand for 24 hours;

[0090] S2, put the panel 18 on the waterproof sealing gasket 16, so as to suspend and fix the detection device on the waterproof sealing gasket 16, and adjust the fastening bolts 24 to fix it;

[0091] S3, placing a counterweight 21 on the lower tray 20 and gradually increasing the weight of the counterweight 21 until the waterproof gasket 16 partially falls off, and determining the average load-bearing value of the adhesive force of the waterproof gasket 16; specifically, performing counterweight tests multiple times at different locations, and after eliminating abnormal data from the multiple tests, determining the average load-bearing value of the gasket;

[0092] S4, customizing the corresponding matching weight block according to the average load-bearing value of the waterproof sealing gasket 16;

[0093] S5, after the waterproof sealing gasket 16 is attached, let it stand for 24 hours, fix the panel 18 on the waterproof sealing gasket 16, and place the matching counterweight on the lower tray 20;

[0094] S6. Determine the adhesive strength of waterproof gasket 16 based on cracking conditions at the adhesive area of ​​waterproof gasket 16. Specifically, if the gasket is peeling off and cracking from the groove, the adhesive strength at that location is considered unsatisfactory. The gasket needs to be removed in whole or in part, cleaned, and re-applied and measured to ensure that the adhesive strength meets the stress level after the gasket is adhered, thereby ensuring adhesive quality.
