Description

Technical Field

[0001] This invention relates to the field of underwater concrete pouring technology, specifically to a scanning and monitoring device and method for the entire process of underwater concrete pouring in deep holes or trenches. Background Technology

[0002] In existing deep-hole and deep-trench concrete construction technologies, it is usually impossible to observe the internal state of the concrete during underwater concrete pouring, and it is also impossible to accurately assess the state of slag and silt at the bottom of the hole (trench). Furthermore, it is impossible to monitor emergencies such as slag inclusion caused by hole wall collapse during concrete pouring in real time. In addition, the existing technology, which uses measuring ropes, suffers from poor environmental conditions and low measurement efficiency due to rope contamination during each measurement and depth measurement operation. Summary of the Invention

[0003] The purpose of this invention is to provide a scanning and monitoring device and method for underwater concrete pouring in deep holes or trenches, so as to solve the problems mentioned in the background art.

The outer gear of the adjusting gear meshes with the long gear. When the screw part of the square-headed lead screw is driven by the rotation of the adjusting gear, the square cap limits the rotation of the square-headed lead screw, thus converting the rotational motion of the adjusting gear into linear motion.

[0008] In a preferred embodiment, a groove is provided on the inner wall of the top of the submersible's upper shell for installing a sealing ring to prevent water from entering the submersible's interior. A square cap at the upper end of the square-headed screw is placed in the top groove of the submersible's upper shell, and a retaining plate is provided at the lower part of the groove to restrict the square-headed screw inside the submersible's upper shell. A positioning inner cover is provided on the top of the submersible's bottom shell, and the square-headed screw passes through the center of the positioning inner cover and extends into the submersible's core shell.

[0009] In a preferred embodiment, a lower scanner is provided at the center of the bottom of the submersible's bottom hull, a horizontal step is provided on the outer wall of the submersible's bottom hull, the lower end of the submersible's upper hull corresponds to the position of the horizontal step, and multiple sets of specific gravity adjustment receivers and specific gravity adjustment control transmitters are provided on the lower end of the submersible's upper hull and the horizontal step, and parallel scanners are provided around the bottom hull of the submersible at the edge of the horizontal step.

[0013] In a preferred embodiment, the outer wall of the submersible's bottom hull is provided with a dial, and the submersible actuator is wrapped with a polytetrafluoroethylene corrugated sealing jacket. Multiple sealing rings are provided between the outer wall above the horizontal step of the submersible's bottom hull and the inner wall of the submersible's upper hull.

[0014] This invention also provides a method for full-process scanning and monitoring of underwater concrete pouring in deep holes or trenches, comprising the following steps:

[0015] S1. Adjust the specific gravity of the submersible actuator to 1.0~1.2t / m 3 The submersible actuator is lowered into a deep hole or trench by pulling a rope, and the submersible actuator is continuously lowered by increasing its specific gravity. At the same time, a submersible scanning operation is performed to obtain the stability of the deep hole or trench wall and the condition of sediment and silt at the bottom of the deep hole or trench before concrete pouring.

[0016] S2. During underwater concrete pouring, adjust the specific gravity of the submersible actuator to 1.2–1.8 t / m. 3 Between, and keep the submersible actuator at the interface between mud and concrete, start pouring concrete, and the interface gradually rises. At this time, the position information is transmitted to the ultrasonic position receiver through the submersible head position transmitter. The ultrasonic position receiver sends the position information to the control terminal, and the control terminal sends the position information to the user terminal, thereby measuring the height of the concrete liquid level in real time and dynamically.

[0017] S3. Continue to adjust the specific gravity of the submersible actuator to be greater than 1.8t / m. 3 The weight of the submersible actuator is continuously increased to make it descend continuously. At the same time, a submersible scanning operation is performed to check whether there is any soil from the hole wall collapsing into the concrete during the concrete pouring process, which could cause slag inclusion.

[0018] S4. After completing the above operations, when the submersible actuator needs to surface, adjust the specific gravity of the submersible actuator to less than 1.0 t / m. 3 ;

[0019] The specific gravity adjustment process of the submersible actuator includes: the control terminal sends an instruction, the programming module receives the instruction, controls the servo motor to start, the servo motor drives the long gear to rotate through the power output shaft, the long gear drives the adjusting gear to rotate, the internal thread of the adjusting gear drives the square head screw to move up and down in the vertical direction, and the square head screw drives the upper shell of the submersible to move up and down, thereby adjusting the specific gravity of the submersible actuator by changing the volume of the cavity between the bottom shell and the upper shell of the submersible.

[0020] The descent scanning process includes: the control terminal issuing a descent scanning command, the lower scanner and the parallel scanner performing scanning operations and transmitting image scanning information to the control terminal, the control terminal sending the image scanning information to the user terminal, and the user terminal drawing a scanned image based on the received image scanning information.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention. Example

[0031] like Figures 1 to 5 As shown, the preferred embodiment of the present invention provides a full-process scanning and monitoring device for underwater concrete pouring in deep holes or trenches, comprising: a submersible actuator 1, a traction rope 2, a ground support 3, and a control terminal 4. The submersible actuator 1 is connected to the ground support 3 via the traction rope 2, with one end of the traction rope 2 attached to the submersible actuator 1 and the other end attached to the ground support 3. If the submersible actuator 1 malfunctions during operation and cannot automatically surface for recovery, it can be pulled out of the water surface via the traction rope 2. The submersible actuator 1 extends into the deep hole or trench, and the control terminal 4 is signal-connected to the submersible actuator 1. The submersible actuator 1 includes a bottom shell 11 and an upper shell 12. The bottom shell 11 is inserted into the upper shell 12. The bottom shell 11 and the upper shell 12 can slide relative to each other. A cavity is provided between the bottom shell 11 and the upper shell 12. The specific gravity of the submersible actuator 1 can be adjusted by changing the volume of the cavity.

[0032] Furthermore, a submersible core shell 13 is provided inside the submersible bottom shell 11. A square-headed lead screw 14 is fixedly installed at the center of the inner wall of the submersible upper shell 12. The square-headed lead screw 14 extends into the submersible core shell 13. A servo motor 17 is provided on one side of the square-headed lead screw 14. A reducer module 18 is connected to the upper part of the servo motor 17. One end of the power output shaft 19 is connected to the output end of the reducer module 18. The other end of the power output shaft 19 is connected to one end of a long gear 15. The other end of the long gear 15 is connected to a gear shaft seat 16 fixed on one side of the inner wall of the submersible core shell 13. The long gear 15 is vertically installed in the gear shaft seat 16. The servo motor 17 can drive the long gear to rotate. Two adjusting bearing seats 20 are spaced apart on the inner wall of the other side of the submersible core shell 13. A square-headed lead screw 14 passes vertically through the round hole of the adjusting bearing seat 20. An adjusting gear 21 is arranged between the two adjusting bearing seats 20. The function of the adjusting bearing seats is to provide horizontal positioning for the square-headed lead screw 14 and the adjusting gear 21. The center of the adjusting gear 21 is a hollow internal thread structure. The upper end of the square-headed lead screw 14 is a square cap, and the lower end is a standard screw. The screw of the square-headed lead screw 14 passes vertically through the center of the adjusting gear 21 and is threadedly connected to the adjusting gear 21. The outer gear of the adjusting gear 21 meshes with the long gear 15. When the screw part of the square-headed lead screw 14 is driven by the rotation of the adjusting gear 21, the square cap limits the rotation of the square-headed lead screw 14, thus converting the rotational motion of the adjusting gear 21 into linear motion. The square cap at the upper end of the square-headed lead screw 14 is set in the top groove of the upper shell 12 of the submersible. A retaining plate 22 is provided at the lower part of the groove to restrict the square-headed lead screw within the upper shell 12. A positioning inner cover 23 is provided on the top of the bottom shell 11 of the submersible. The square-headed lead screw 14 extends into the core shell 13 of the submersible through the center of the positioning inner cover 23. Driven by the long gear 15, the adjusting gear 21 rotates (the square-headed lead screw 14 does not rotate). The rotational motion is converted into linear motion through the threaded connection between the lead screw 14 and the square-headed lead screw 14, pushing the lead screw 14 upward (or downward), thereby driving the upper shell 12 of the submersible to move upward (or downward), thus changing the internal volume of the submersible actuator.

[0033] Furthermore, a lower scanner 24 is provided at the center of the bottom of the submersible's bottom shell 11, and a horizontal step is provided on the outer wall of the submersible's bottom shell 11. The lower end of the submersible's upper shell 12 corresponds to the position of the horizontal step, and multiple sets of specific gravity adjustment receivers 26 and specific gravity adjustment control transmitters 25 are provided on the lower end of the submersible's upper shell 12 and on the horizontal step. Multiple parallel scanners 27 are provided around the submersible's bottom shell 11 at the edge of the horizontal step. The lower scanner 24 and the parallel scanners 27 can scan the surrounding material according to the instructions of the control terminal 4 and send the scan information to the control terminal 4.

[0034] Furthermore, the submersible's core shell 13 also houses a programming module 31 and a battery 32. The programming module 31 is connected to the servo motor 17 via a signal cable 33, and the battery 32 is connected to the servo motor 17 via a power cable 34. The programming module 31 is also connected to the control terminal 4. A scale 41 is provided on the outer wall of the submersible's bottom shell 11. The scale 41 can be used to calibrate the specific gravity of the submersible actuator 1. Taking underwater concrete pouring as an example, the specific gravity of concrete is 1.8 t / m³, and the specific gravity of mud slurry is 1.0–1.2 t / m³. 3 When it is necessary to monitor the concrete pouring height, the specific gravity of the submersible actuator should be adjusted to 1.2–1.8 t / m. 3 When it is necessary to submerge in concrete for ultrasonic scanning, the specific gravity of the submersible actuator should be adjusted to be greater than 1.8 t / m. 3 When the submersible actuator needs to surface, the specific gravity of the submersible actuator should be adjusted to less than 1.0 t / m. 3 The specific gravity adjustment receiver 26 and the specific gravity adjustment control transmitter 25 are responsible for feeding back position information when the submersible actuator 1 is adjusting its specific gravity. The programming module 13 calculates the overall specific gravity of the submersible actuator 1 based on the distance between the specific gravity adjustment receiver 26 and the specific gravity adjustment control transmitter 25.

[0035] Furthermore, a submersible head position transmitter 29 and a lifting ring 30 are provided on the top outer wall of the submersible upper shell 12. The submersible head position transmitter 29 is used to send the elevation information of the submersible actuator 1 to the ultrasonic position receiver 35 of the ground support 3. The lifting ring 30 is located at the center of the top outer wall of the submersible upper shell 12.

[0036] Furthermore, the ground support 3 includes a vertically arranged support rod 36 and a horizontally arranged support beam 37. An ultrasonic position receiver 35 is installed at the bottom of one end of the support beam 37, and a foot pedal assist device 38 is installed on the support rod 36. The ground support 3 is inserted into the soil around the deep hole or deep trench through the support rod 36, which has a pointed end, to fix the pull rope 2 and the ultrasonic position receiver 35.

[0037] Furthermore, the submersible actuator 1 is encased in a polytetrafluoroethylene corrugated sealing jacket 40 to prevent liquids or sediment from entering the interior of the submersible actuator 1 and affecting its operation. Multiple sealing rings 39 are provided between the outer wall above the horizontal step of the submersible bottom shell 11 and the inner wall of the submersible upper shell 12. Example

[0038] The method flow of the present invention is described below:

[0039] Step S1: Before underwater concrete pouring, obtain information on the stability of the deep hole or trench wall and the condition of sediment and silt at the bottom of the deep hole or trench:

[0040] First, adjust the submersible actuator to a suitable specific gravity, since the specific gravity of the mud is 1.0–1.2 t / m³. 3 At this point, adjust the specific gravity of the submersible actuator 1 to 1.0–1.2 t / m. 3 The submersible actuator 1 is lowered into the deep hole or trench by pulling rope 2, and the specific gravity of the submersible actuator 1 is continuously increased to make the submersible actuator 1 descend continuously. At the same time, a submersible scanning operation is performed to obtain the stability of the deep hole or trench wall and the condition of sediment and silt at the bottom of the deep hole or trench before concrete pouring in real time.

[0041] Step S2: During underwater concrete pouring, the height of the concrete level is measured in real time and dynamically.

[0042] Because the specific gravity of concrete is 1.8t / m³ 3 During underwater concrete pouring, the specific gravity of the submersible actuator should be adjusted to 1.2–1.8 t / m. 3 The submersible actuator 1 is positioned between the mud and concrete, ensuring that it remains at the interface between the mud and concrete. Once the concrete begins to be poured, the interface gradually rises. At this time, the submersible head position transmitter 29 transmits position information to the ultrasonic position receiver 35, which then sends the position information to the control terminal 4. The control terminal 4 then sends the position information to the user terminal, thereby enabling real-time monitoring of the concrete pouring height.

[0043] Step S3: During the underwater concrete pouring process, check for any soil from the borehole wall collapsing into the concrete, causing slag (mud) inclusions.

[0044] Continue to adjust the specific gravity of the submersible actuator to be greater than 1.8 t / m. 3 The weight of the submersible actuator 1 is continuously increased, causing it to descend continuously. At the same time, a submersible scanning operation is performed to check whether there is any problem of soil from the hole wall collapsing into the concrete during the concrete pouring process, resulting in slag (mud) inclusion.

[0045] Step S4: After completing the above operations, when the submersible actuator needs to surface, adjust the specific gravity of the submersible actuator to less than 1.0 t / m. 3 .

[0046] Specifically, the gravity adjustment process of the submersible actuator:

[0047] The control terminal 4 issues a command, and the programming module 31 receives the command and controls the servo motor 17 to start. The servo motor 17 drives the long gear 15 to rotate through the power output shaft 19. The long gear 15 drives the adjusting gear 21 to rotate. The internal thread of the adjusting gear 21 drives the square-headed lead screw 14 to move up and down in the vertical direction. The square-headed lead screw 14 drives the upper shell 12 of the submersible to move up and down. The specific gravity of the submersible actuator 1 is adjusted by changing the volume of the cavity between the bottom shell 11 and the upper shell 12 of the submersible. The specific gravity adjustment receiver 26 and the specific gravity adjustment control transmitter 25 are used to provide position information when the specific gravity of the submersible actuator 1 is adjusted. The programming module 31 calculates the overall specific gravity of the submersible actuator 1 based on the distance between the specific gravity adjustment receiver 26 and the specific gravity adjustment control transmitter 25.

[0048] Submersible scanning process:

[0049] The control terminal 4 issues a dive scan command, and the lower scanner 24 and the parallel scanner 27 perform scanning operations and transmit image scanning information to the control terminal 4. The control terminal 4 sends the image scanning information to the user terminal, and the user terminal draws the scanned image based on the received image scanning information.
