Description

Technical Field

[0001] This application relates to the field of prefabricated building construction, and in particular to a tracking and monitoring device and intelligent control method for sleeve-combined grouting. Background Technology

[0002] In prefabricated construction, when installing wall panels onto floor slabs, sleeves are used to fit the reinforcing bars on the bottom of the wall panels and the reinforcing bars on the floor slab. The sleeves have an outlet and an inlet for grout. An air compressor and a grout tank are placed on the floor slab. The grout tank is connected to the inlet of the sleeve, and the tank stores grout material. The air compressor is used to deliver the grout material from the grout tank into the inlet of the sleeve. Generally, multiple sleeves are used when connecting wall panels to floor slabs, and the grout material is always injected from the same inlet of the same sleeve.

[0003] There is a pouring cavity between the wall panel and the floor slab. After grout is poured into the sleeve, the grout first flows downwards to fill the pouring cavity. After the pouring cavity is filled, the grout gradually fills the sleeve. During the process of the grout gradually filling the sleeve, the grout will squeeze out the air in the sleeve. The air is discharged from the grout outlet of the sleeve. Therefore, it is necessary to control the rising speed of the grout inside the sleeve. If the rising speed of the grout inside the sleeve is too fast, a situation may occur where the grout inside the sleeve is higher than the grout outlet before the air inside the sleeve has been discharged.

[0004] However, since the sleeve is inside the wall panel, construction workers cannot see the rising speed of the grout inside the sleeve. Therefore, they need to rely on their experience to control the air pressure of the air compressor to adjust the rising speed of the grout, which increases the difficulty of sleeve grouting. Summary of the Invention

[0005] To facilitate the adjustment of the rising speed of the grout inside the sleeve, this application provides a tracking and monitoring device and intelligent control method for sleeve combined grouting.

[0006] This application provides a tracking and monitoring device and intelligent control method for sleeve-combined grouting, which adopts the following technical solution:

[0007] A tracking and monitoring device for sleeve-type combined grouting includes a float inside the sleeve and a distance sensor outside the sleeve. A suspension rope is connected between the float and the distance sensor, and the suspension rope is used to pass through the grout outlet of the sleeve. The weight of the float is greater than that of the distance sensor, and the size of the float is smaller than that of the grout outlet of the sleeve. The distance sensor is electrically connected to a controller. The distance sensor is used to generate distance information based on the lifting height and send it to the controller. The controller controls the grouting speed based on the distance information.

[0008] By adopting the above technical solution, after the grout enters the sleeve, the float rises due to the buoyancy of the grout, causing the distance sensor to descend. The controller obtains the rising speed of the grout inside the sleeve based on the descent speed of the distance sensor. The controller then adjusts the grouting speed according to the rising speed of the grout inside the sleeve, thus facilitating the adjustment of the grout's rising speed within the sleeve.

[0009] When the grout inside the sleeve is about to be filled, the float is removed from the sleeve for reuse, thus saving resources.

[0010] Optionally, the distance sensor is provided with a slide rail, the slide rail is vertically arranged, the distance sensor is mounted on the slide rail for lifting and sliding, the slide rail is fixedly installed with a fixing tube, the fixing tube is damped and inserted into the paddle outlet of the sleeve, and the suspension rope is threaded through the fixing tube.

[0011] By adopting the above technical solution, the slide rail facilitates the lifting and sliding of the distance sensor, while reducing the occurrence of the distance sensor shaking due to wind, thereby improving the accuracy of detecting the rising speed of the grouting material inside the sleeve.

[0012] Optionally, a slurry guide pipe is also included, which passes through the slurry outlet of the sleeve. A plug is fixedly installed on the body of the slurry guide pipe to block the slurry outlet of the sleeve. A detection pipe is connected to one end of the slurry guide pipe outside the slurry outlet of the sleeve. The detection pipe is vertically arranged, and a push plate is slidably arranged inside the detection pipe. A pressure sensor is fixedly installed at the top of the detection pipe. A spring is fixedly installed between the pressure sensor and the push plate. The spring is used to drive the push plate to move downward. The pressure sensor is electrically connected to the controller. The pressure sensor is used to generate a pressure signal based on the pressure from the spring and send it to the controller. The controller determines whether the sleeve is full based on the pressure signal.

[0013] By employing the above technical solution, after the grout overflows from the outlet of the sleeve, the construction personnel insert a guide pipe into the outlet of the sleeve. Subsequently, when the sleeve is filled with grout, the grout inside the sleeve flows from the guide pipe into the detection tube. The grout inside the detection tube drives the push plate upward, compressing the spring and increasing the pressure detected by the pressure sensor. After grouting stops, the controller repeatedly acquires the pressure detected by the pressure sensor. If the pressure detected by the pressure sensor drops, there may be leakage of grout inside the sleeve, requiring the construction personnel to replenish the grout, thus helping to maintain a full grout level inside the sleeve.

[0014] Optionally, an intelligent control method for sleeve combination grouting includes the following steps during the grouting process:

[0015] Acquire first distance information, which is the initial height of the distance sensor before grouting;

[0016] Acquire second distance information, which is the current height of the distance sensor;

[0017] Determine if the first distance information is greater than the second distance information; if yes, prompt to block the slurry inlet of the sleeve; if no, return to obtain the second distance information.

[0018] After reminding the sealing sleeve to open the grout inlet, the third distance information is obtained, which is the current height of the distance sensor;

[0019] The rising information is obtained based on the first distance information and the third distance information. The rising information is the height of the float rising and the difference between the first distance information and the third distance information.

[0020] Obtain the rise threshold, which is the height at which the float needs to be removed from the sleeve;

[0021] Determine if the rising information is greater than the rising threshold; if so, prompt the blocking of the slurry outlet of the sleeve and disconnect the electrical connection of the distance sensor corresponding to the rising information, then return to obtain the third distance information; if not, return to obtain the third distance information.

[0022] By adopting the above technical solution, when the grout inside the sleeve rises close to the grout outlet and inlet of the sleeve, the controller reminds the construction personnel to seal it, thus facilitating timely sealing of the grout outlet and inlet of the sleeve and reducing grout waste. After sealing the grout outlet of the sleeve, the controller disconnects the electrical connection with the corresponding distance sensor of the sleeve, thereby reducing the need for repeated activation of the distance sensor for detection and thus achieving energy saving.

[0023] Optionally, before determining that the rising information is less than the rising threshold and returning to obtain the third distance information, the following steps are also included:

[0024] Acquire speed information, wherein the speed information is the rising speed of the float;

[0025] Obtain a first speed threshold and a second speed threshold, wherein the first speed threshold is a preset maximum rising speed of the floating block, and the second speed threshold is a preset minimum rising speed of the floating block;

[0026] Adjust the rising speed of the float between the first and second speed thresholds based on the speed information, and then return to obtain the third distance information.

[0027] By adopting the above technical solution, the rising speed of the grout inside the sleeve is adjusted to be between the first speed threshold and the second speed threshold, which facilitates the timely discharge of air inside the sleeve and thus facilitates the filling of the sleeve with grout.

[0028] Optionally, adjusting the rising speed of the float between a first speed threshold and a second speed threshold based on the speed information includes the following steps:

[0029] Acquire amplitude adjustment information, which is the amplitude of each adjustment to the grouting pressure;

[0030] Determine if the speed information is greater than the first speed threshold; if so, reduce the grouting pressure according to the amplitude adjustment information and return to obtain the speed information; if not, determine if the speed information is less than the second speed threshold.

[0031] After determining whether the speed information is less than the second speed threshold, if so, the grouting pressure is increased according to the amplitude adjustment information, and the speed information is returned; if not, the third distance information is returned.

[0032] By adopting the above technical solution, the grouting pressure is gradually reduced or increased, so that the rising speed of the grouting material inside the sleeve falls between the first speed threshold and the second speed threshold, thereby facilitating the adjustment of the rising speed of the grouting material inside the sleeve.

[0033] Optionally, obtaining speed information includes the following steps:

[0034] Obtain the detection interval, which is a preset time interval;

[0035] After waiting for the detection interval, the fourth distance information is obtained. The fourth distance information is the height change of the distance sensor corresponding to the maximum rise information during the detection interval.

[0036] Speed ​​information is obtained based on the fourth distance information and the detection interval, wherein the speed information is the fourth distance information excluding the detection interval.

[0037] By adopting the above technical solution, the distance sensor calculates the rising speed of the grout inside the sleeve by measuring the distance change within the detection interval, thus facilitating the monitoring of the rising speed of the grout inside the sleeve.

[0038] Optionally, after reminding the blockage sleeve to open the slurry outlet and disconnecting the electrical connection of the distance sensor corresponding to the rising information, before returning to obtain the third distance information, the following steps are included:

[0039] Acquire first pressure information, which is the current pressure detected by the pressure sensor;

[0040] Obtain a first pressure threshold, which is a preset pressure detected by the pressure sensor after the sleeve is filled, and the first pressure threshold is lower than the actual pressure detected by the pressure sensor after the sleeve is filled.

[0041] Determine whether the first pressure information is greater than the first pressure threshold; if yes, return to obtain the third distance information; if no, return to obtain the first pressure information.

[0042] By employing the above technical solution, once the pressure detected by the pressure sensor exceeds the first pressure threshold, the grouting material inside the sleeve has been filled. The controller then returns to retrieve the third distance information, facilitating the adjustment of the grouting material rising speed inside the other sleeve.

[0043] Optionally, the following steps may be included after grouting is stopped:

[0044] Acquire the second pressure information, which is the initial pressure detected by the pressure sensor after the sleeve grouting is completed;

[0045] Obtain a second pressure threshold, which is a preset threshold;

[0046] Acquire third pressure information, which is the pressure currently detected by the pressure sensor;

[0047] Determine whether the difference between the second pressure information and the third pressure information is less than the second pressure threshold; if yes, return to obtain the third pressure information; if no, alert that the grouting material inside the sleeve corresponding to the third pressure information is leaking.

[0048] By adopting the above technical solution, after grouting is stopped, the pressure changes before and after the pressure sensor are compared, which makes it easy to determine whether the grout inside the sleeve is leaking, and thus makes it easier for construction personnel to replenish the leaking sleeve.

[0049] Optionally, after obtaining the second pressure information of the sleeve, the following steps are also included:

[0050] Displays information for each second pressure level;

[0051] Obtain instruction information, which includes executing the next step or returning to the previous step;

[0052] Determine if the instruction information indicates the next step; if yes, proceed to obtain the second pressure threshold; otherwise, return to obtain the second pressure information.

[0053] By adopting the above technical solution, construction workers can check whether each sleeve is filled with grout by gradually increasing the second pressure information. After the construction workers detect the first sleeve that is filled with grout, the testing of other sleeves is stopped, thereby reducing the workload of the construction workers.

[0054] In summary, this application includes at least one of the following beneficial technical effects:

[0055] The grout enters the sleeve, causing the float to rise and the distance sensor to fall. The distance sensor detects the height in real time and sends it to the controller. The controller calculates the rising speed of the grout inside the sleeve based on the falling speed of the distance sensor. Then, the controller adjusts the grouting pressure according to the rising speed of the grout inside the sleeve, thus making it easy to adjust the rising speed of the grout inside the sleeve.

[0056] After the grout overflows from the outlet of the sleeve, the guide pipe and plug are placed into the outlet of the sleeve. After grouting is completed, the grout enters the detection pipe from the guide pipe. Then the grout pushes the push plate upward, the push plate compresses the spring, and the controller records the pressure detected by the pressure sensor to form the initial pressure. After the grout leaks inside the sleeve, the spring returns to its original state and drives the push plate to move downward. The pressure detected by the pressure sensor decreases. The controller can easily determine whether the sleeve is leaking based on the pressure changes detected by the pressure sensor, and thus facilitate the construction personnel to replenish the leaking sleeve.

[0068] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0069] This application discloses a tracking and monitoring device and intelligent control method for combined grouting of sleeve 1.

[0070] Reference Figure 1 , Figure 2 , Figure 3 The grouting process typically involves multiple sleeves 1 positioned on the bottom side of the floor slab. Each sleeve 1 has a grout outlet 2 and a grout inlet 3. A pouring cavity 4 exists between the wall panel and the floor slab. The reinforcing bars on the bottom side of the wall panel and the reinforcing bars of the floor slab are inserted into the sleeves 1.

[0071] An air compressor 5 and a grout tank 6 are placed on the floor slab. The grout tank 6 is connected to the grout inlet 3 of the sleeve 1, and the grout tank 6 stores grout material. The air compressor 5 is used to deliver the grout material from the grout tank 6 into the grout inlet 3 of the sleeve 1. When the air compressor 5 is started, it delivers the grout material from the grout tank 6 into the grout inlet 3 of the sleeve 1. The grout material first fills the casting cavity 4, and then gradually fills the sleeve 1.

[0072] Reference Figure 4 A tracking and monitoring device for grouting assembly using a sleeve 1 includes a float 7 disposed inside the sleeve 1 and a distance sensor 8 disposed outside the sleeve 1. A suspension rope 9 is connected between the float 7 and the distance sensor 8, and the suspension rope 9 is used to pass through the grout outlet 2 of the sleeve 1. The weight of the float 7 is greater than that of the distance sensor 8. The distance sensor 8 is electrically connected to a controller 18.

[0073] As the grout gradually fills the sleeve 1, the float 7 moves upward under the buoyancy of the grout, causing the distance sensor 8 to descend. The distance sensor 8 generates distance information based on the height change and sends it to the controller 18. The controller 18 calculates the rising speed of the float 7 based on the height change of the distance sensor 8, and thus obtains the rising speed of the grout inside the sleeve 1.

[0074] Reference Figure 4The size of the float 7 is smaller than the grout outlet 2 of the sleeve 1. After the grout overflows from the grout outlet 2 of the sleeve 1, the hoisting rope 9 is pulled to remove the float 7 from the sleeve 1 for recycling, thus saving resources. The size of the distance sensor 8 is larger than the grout outlet 2 of the sleeve 1, thereby reducing the possibility of the distance sensor 8 entering the inside of the sleeve 1 under the influence of the float 7.

[0075] Reference Figure 4 The distance sensor 8 is mounted on a slide rail 10, which is vertically positioned. The distance sensor 8 is slidably mounted on the slide rail 10. A fixing pipe 11 is fixedly installed on the slide rail 10, and the fixing pipe 11 is damped and inserted into the paddle outlet of the sleeve 1. The suspension rope 9 is threaded through the fixing pipe 11. The distance sensor 8 slides inside the slide rail 10, thereby reducing the swaying of the distance sensor 8 under wind conditions.

[0076] Reference Figure 5 It also includes a grout guide pipe 12, which passes through the grout outlet 2 of the sleeve 1. A plug 13 is fixedly installed on the body of the grout guide pipe 12, and the plug 13 is tightly pressed against the outer wall of the grout guide pipe 12 and the inner wall of the grout outlet 2 of the sleeve 1. A detection pipe 14 is fixedly connected to one end of the grout guide pipe 12 located outside the grout outlet 2 of the sleeve 1, and the detection pipe 14 is vertically arranged.

[0077] A push plate 15 is installed inside the detection tube 14, allowing it to slide vertically. A pressure sensor 16 is fixedly installed at the top of the detection tube 14. A spring 17 is fixedly installed between the pressure sensor 16 and the push plate 15, and the spring 17 is used to drive the push plate 15 to move downward. The pressure sensor 16 is electrically connected to the controller 18.

[0078] After the float 7 is removed from the sleeve 1, the feed pipe and the plug 13 are inserted into the grout outlet 2 of the sleeve 1. Then, the grout inside the sleeve 1 enters the detection pipe 14 through the feed pipe. The grout pushes the push plate 15 upwards, compressing the spring 17, thereby increasing the pressure detected by the pressure sensor 16. The pressure sensor 16 generates a pressure signal based on the detected pressure and sends it to the controller 18.

[0079] After grouting stops, the controller 18 acquires the pressure detected by the pressure sensor 16 to form the initial pressure. Subsequently, during the solidification process of the grout inside the sleeve 1, if there is a leak, the pressure detected by the pressure sensor 16 decreases. The controller 18 uses the pressure changes before and after the pressure sensor 16 to easily monitor whether the sleeve 1 is leaking, thus facilitating timely replenishment of any leaking sleeve 1 by construction personnel.

[0080] Reference Figure 6 A smart control method for combined grouting with sleeve 1, applied to a tracking and monitoring device for combined grouting with sleeve 1 in the embodiments of this application, includes the following steps during the grouting process:

[0081] S1. Obtain the first distance information. Then proceed to step S2.

[0082] Before grouting begins, each distance sensor 8 detects the distance to the floor slab and sends it to the controller 18, thereby enabling the controller 18 to acquire first distance information. The first distance information is the initial height of the distance sensor 8 before grouting.

[0083] S2, Obtain the second distance information.

[0084] Each distance sensor 8 detects the height of the distance from the floor and sends it to the controller 18, thereby enabling the controller 18 to obtain the second distance information.

[0085] S3. Determine whether the first distance information is greater than the second distance information; if yes, proceed to step S4; if no, return to step S2.

[0086] S4. Remind the user to seal the slurry inlet 3 of sleeve 1. Then proceed to step S5.

[0087] After the distance sensor 8 descends, the first distance information will be greater than the second distance information, and grout will enter the sleeve 1. Therefore, construction personnel need to check the grout inlet 3 of the sleeve 1 where the first distance information is greater than the second distance information. Grout overflowing from the grout inlet 3 of the sleeve 1 should be promptly sealed to reduce grout waste. When the distance sensor 8 has not descended, the first distance information is equal to the second distance information, and the amount of grout entering the sleeve 1 is small or has not yet entered, so construction personnel do not need to observe the grout inlet 3 of the sleeve 1.

[0088] S5. Obtain the third distance information. Then proceed to step S6.

[0089] The distance sensor 8 corresponding to the sleeve 1, which has been sealed at the grout inlet 3, detects the height of the distance from the floor slab and sends it to the controller 18, thereby enabling the controller 18 to obtain the third distance information.

[0090] S6. Obtain ascent information based on the first distance information and the third distance information. Then proceed to step S7.

[0091] The rise information is used to indicate the height at which the float 7 rises. The height at which the float 7 rises is equal to the height at which the distance sensor 8 falls. The controller 18 calculates the difference between the first distance information and the third distance information, thereby enabling the controller 18 to acquire the rise information.

[0092] S7. Obtain the rising threshold. Then proceed to step S8.

[0093] The rising threshold is the value pre-entered by the construction personnel into the controller 18. The rising threshold is the height at which the float 7 needs to be removed from the sleeve 1. Generally, the rising height of the float 7 is close to the slurry outlet 2 of the sleeve 1.

[0094] Reference Figure 7 S8. Determine whether the rising information is greater than the rising threshold; if yes, proceed to step S9; if no, proceed to step S13.

[0095] S9. Remind the user to stop the slurry outlet 2 of the sealing sleeve 1 and disconnect the electrical connection of the distance sensor 8 corresponding to the rising information. Then proceed to step S10.

[0096] Once the float 7 rises above the rising threshold, the grout inside the sleeve 1 will be filled. The controller 18 promptly alerts the construction personnel to remove the float 7 corresponding to the rising information exceeding the rising threshold from the sleeve 1. Afterward, the construction personnel wait for the grout to overflow from the outlet 2 of the sleeve 1, and then use the guide pipe and plug 13 to seal the outlet 2 of the sleeve 1, reducing the need for the construction personnel to repeatedly check whether there is any grout overflow from the outlet 2 of the sleeve 1.

[0097] S10. Obtain the first pressure information. Then proceed to step S11.

[0098] The first pressure information is the current pressure detected by the pressure sensor 16 and sent to the controller 18, so that the controller 18 can obtain the first pressure information.

[0099] S11. Obtain the first pressure threshold. Then proceed to step S12.

[0100] The first pressure threshold is the preset pressure detected by the pressure sensor 16 after the sleeve 1 is filled. The first pressure threshold is lower than the actual pressure detected by the pressure sensor 16 after the sleeve 1 is filled.

[0101] S12. Determine whether the first pressure information is greater than the first pressure threshold; if yes, return to step S5; if no, return to step S10.

[0102] When the first pressure information is greater than the first pressure threshold, the inside of sleeve 1 will be filled, thus returning to step S5, which facilitates the adjustment of the rising speed of the grouting material inside other sleeves 1.

[0103] When the first pressure information is less than the first pressure threshold, there is less grout inside the sleeve 1, which makes it easier to maintain the rising speed of the grout inside the sleeve 1, and thus makes it easier for the grout to fill the sleeve 1.

[0104] S13. Obtain speed information. Then proceed to step S14.

[0105] The speed information is the rising speed of float 7.

[0106] Reference Figure 8 Step S13 includes the following steps:

[0107] S131. Obtain the detection interval. Then proceed to step S132.

[0108] The detection interval is a preset time interval.

[0109] S132. After waiting for the detection interval, obtain the fourth distance information. Then proceed to step S133.

[0110] The distance sensor 8 corresponding to the maximum rise information sends the front and rear heights between detection intervals to the controller 18, and the controller 18 forms the fourth distance information based on the front and rear height differences of the distance sensor 8.

[0111] S133. Obtain speed information based on the fourth distance information and the detection interval. Then proceed to step S14.

[0112] Speed ​​information is the fourth distance information excluding the detection interval.

[0113] Reference Figure 7 S14. Obtain the first speed threshold and the second speed threshold. Then execute step S15.

[0114] The construction workers input the required speed range for the rising grout inside sleeve 1 into controller 18. Controller 18 then generates a first speed threshold and a second speed threshold based on this speed range. The first speed threshold is the preset maximum rising speed of float 7, and the second speed threshold is the preset minimum rising speed of float 7.

[0115] S15. Adjust the rising speed of float 7 between the first speed threshold and the second speed threshold based on the speed information. Then return to step S5.

[0116] The rising speed of the float 7 is adjusted between the first speed threshold and the second speed threshold, so that the rising speed of the grout inside the sleeve 1 is also between the first speed threshold and the second speed threshold, thereby reducing the situation where the rising speed of the grout inside the sleeve 1 is too fast and air is not expelled.

[0117] Reference Figure 9 Step S15 includes the following steps:

[0118] S151. Obtain amplitude modulation information. Then proceed to step S152.

[0119] The amplitude adjustment information refers to the magnitude of each adjustment to the grouting pressure.

[0120] S152. Determine whether the speed information is greater than the first speed threshold; if yes, proceed to step S153; if no, proceed to step S154.

[0121] S153. Adjust the grouting pressure according to the amplitude adjustment information. Then return to step S13.

[0122] When the speed information exceeds the first speed threshold, the grout material inside the sleeve 1 rises rapidly. The controller 18 reduces the pressure pumped by the air compressor 5 based on the amplitude modulation information, thereby reducing the rising speed of the grout material inside the sleeve 1.

[0123] S154. Determine whether the speed information is less than the second speed threshold; if yes, proceed to step S155; if no, return to step S5.

[0124] S155. Increase the grouting pressure according to the amplitude adjustment information. Then return to step S13.

[0125] When the speed information is less than the second speed threshold, the grout material inside the sleeve 1 rises slowly. The controller 18 increases the pressure pumped by the air compressor 5 according to the amplitude modulation information, thereby increasing the rising speed of the grout material inside the sleeve 1.

[0126] Reference Figure 10 After grouting is stopped, the following steps are included:

[0127] S16. Obtain the second pressure information. Then proceed to step S17.

[0128] After grouting stops, the controller 18 acquires the pressure detected by each pressure sensor 16, thereby forming second pressure information. The second pressure information corresponds one-to-one with each pressure sensor 16.

[0129] S17. Display the information for each second pressure. Then proceed to step S18.

[0130] Construction workers use the second pressure information to check whether each sleeve 1 is filled with grout in stages, from low to high. Once the construction workers detect the first sleeve 1 that is filled with grout, the testing of other sleeves 1 is stopped, thereby reducing the workload of the construction workers.

[0131] S18. Obtain instruction information. Then proceed to step S19.

[0132] The instruction information includes either "Execute the next step" or "Return to the previous step." After the construction personnel check whether sleeve 1 is filled with grout, if any sleeve 1 is not filled with grout, the construction personnel will add grout and then input "Return to the previous step" to the controller 18. If each sleeve 1 is filled with grout, the construction personnel will input "Next step" to the controller 18.

[0133] S19. Determine if the instruction information is to execute the next step; if yes, execute step S20; if no, return to execute step S16.

[0134] After replenishing the unfilled sleeve 1, the controller 18 returns to step S16, thereby updating the second pressure information.

[0135] S20. Obtain the second pressure threshold. Then proceed to step S21.

[0136] The second pressure threshold is a preset value.

[0137] S21. Obtain the third pressure information. Then proceed to step S22.

[0138] The third pressure information is the pressure currently detected by pressure sensor 16.

[0139] S22. Determine whether the difference between the second pressure information and the third pressure information is less than the second pressure threshold; if yes, return to step S21; if no, proceed to step S23.

[0140] S23. A reminder that the grouting material inside sleeve 1 corresponding to the third pressure information is leaking.

[0141] When the pressure change detected by pressure sensor 16 exceeds the second pressure threshold, the construction personnel replenish the sleeve 1 corresponding to the third pressure information to keep the grouting material inside each sleeve 1 full. When the grouting material inside the sleeve 1 has initially set, the pouring cylinder and the plug 13 are removed from the grout outlet 2 of the sleeve 1.

[0142] The implementation principle of the tracking and monitoring device and intelligent control method for combined grouting of sleeve 1 in this application embodiment is as follows: After the grout enters the sleeve 1, the grout drives the float 7 to move upward, and then the distance sensor 8 moves downward. The controller 18 calculates the rising speed of the grout inside the sleeve 1 based on the rising and falling speed of the distance sensor 8.
