Description

Technical Field

[0001] The present invention relates to the technical field of bored cast-in-place pile construction, and particularly to an intelligent measuring system and construction method for the hole depth and sediment thickness of bored cast-in-place piles. Background Art

[0002] Bored cast-in-place piles have the advantages of wide application range, high single-pile bearing capacity, low construction noise, small vibration and low unit price, and have been widely used in various construction projects such as bridges and highways. Therefore, the construction quality control of cast-in-place piles is particularly important. At present, the construction of bored cast-in-place piles includes steps such as drilling, hole cleaning, placing steel reinforcement cages, and underwater pouring of concrete. During the drilling process, sediment will be generated and accumulated at the bottom of the hole. If the sediment is too thick, it will affect the bonding between the concrete and the bedrock, posing a huge potential safety hazard to the overall structure of the superstructure of the pile foundation. Therefore, usually, sediment cleaning is carried out once after drilling. However, when placing the steel reinforcement cage, the steel reinforcement cage collides with the hole wall, generating sediment again. Therefore, the sediment at the bottom of the hole is measured before pouring the concrete. If the sediment thickness at the bottom of the hole is too thick, secondary hole cleaning is required until the sediment thickness at the bottom of the hole meets the standard requirements.

[0003] At present, the commonly used method for measuring the thickness of sediment at the bottom of the hole is the heavy hammer method. The heavy hammer used at the construction site is generally a waste steel bar. The resistance of the steel bar passing through the upper slurry and the lower sediment is different. The surveyor judges the interface between the sediment and the slurry by the feel when pulling the measuring rope, so as to determine the thickness of the sediment. The measurement error is large and the measurement efficiency is low, which is not conducive to the quality control of the pile foundation.

[0004] To sum up, in the prior art, the measurement of the sediment thickness of bored cast-in-place piles depends entirely on the feel of the surveyor, resulting in low measurement efficiency, large measurement errors, and being contrary to the current trend of intelligent construction.

[0034] Please refer to Figures 1 to 3 , Figure 1 Schematic block diagram of the intelligent measurement system for the hole depth and sediment thickness of bored cast-in-place piles provided by an embodiment of the present invention; Figure 2The front view of the measuring device provided by an embodiment of the present invention; Figure 3 The top view of the measuring device provided by another embodiment of the present invention. Among them, Figure 1 It can also be understood as a schematic block diagram of the communication connection relationship between the background terminal, the measuring device and the user terminal in the intelligent measuring system for the hole depth and sediment thickness of bored cast-in-place piles provided by an embodiment of the present invention.

[0035] The intelligent measuring system for the hole depth and sediment thickness of bored cast-in-place piles provided by the embodiments of the present invention includes: a measuring device 1, a background terminal 2 and a user terminal 3; the measuring device 1 includes a weight assembly 11, a measuring rope mechanism 12, a length sensor 13 and a density sensor 14; the top of the weight assembly 11 is connected to the measuring rope 121 inside the measuring rope mechanism 12, the length sensor 13 is arranged on the measuring rope mechanism 12, and the density sensor 14 is arranged on the side wall of the weight assembly 11; the background terminal 2 is communicatively connected to the length sensor 13 and the density sensor 14 in the measuring device 1, and the background terminal 2 is also communicatively connected to the user terminal 3;

[0036] The length sensor 13 is used to measure the length data of the measuring rope 121 extending from the measuring rope mechanism 12 in real time and upload it to the background terminal 2;

[0037] The density sensor 14 is used to measure the density data of the liquid inside the formed hole of the bored cast-in-place pile to be measured in real time and upload it to the background terminal 2;

[0038] The background terminal 2 is used to obtain the first measurement data based on the length data uploaded by the length sensor 13, and obtain the hole depth according to the first measurement data and the height of the weight assembly 11; wherein, the first measurement data is the length data measured by the length sensor 13 when the weight assembly 11 is lowered from the center of the formed hole of the bored cast-in-place pile to the bottom of the hole;

[0039] The background terminal 2 is further used to, after determining that the hole depth is within the preset hole depth range, obtain the second measurement data based on the length data uploaded by the length sensor 13 and the density data uploaded by the density sensor 14, and obtain the sediment thickness according to the first measurement data and the second measurement data; wherein, the second measurement data is the length data measured by the length sensor 13 when the density data measured by the density sensor 14 changes;

[0040] The user terminal 3 is used to receive the hole depth and the sediment thickness sent by the background terminal 2.

[0041] In this embodiment, refer to Figure 1, the measuring device 1 is composed of a plumb bob assembly 11, a measuring rope mechanism 12, a length sensor 13 and a density sensor 14. Among them, a measuring rope 121 is arranged inside the measuring rope mechanism 12. The measuring rope 121 is connected to the top of the plumb bob assembly 11. The measuring rope 121 can extend out of or be retracted into the measuring rope mechanism 12. The length sensor 13 is installed on the measuring rope mechanism 12. The length sensor 13 can measure the length data of the measuring rope 121 extending out of the measuring rope mechanism 12. The length sensor 13 can upload the measured length data to the background terminal 2. Further, the length sensor 13 can also display the measured length data. Moreover, the density sensor 14 is installed on the side wall of the plumb bob assembly 11. The density sensor 14 measures the density data of the liquid inside the hole of the to-be-measured cast-in-place bored pile. Preferably, the sensing end of the density sensor 14 is flush with the bottom end of the plumb bob assembly 11.

[0042] During the application process, when the operator needs to measure the hole depth of the to-be-measured cast-in-place bored pile, the operator can activate the length sensor 13 and simultaneously slowly lower the plumb bob assembly 11 from the center of the hole of the to-be-measured cast-in-place bored pile until the plumb bob assembly 11 is lowered to the bottom of the hole of the to-be-measured cast-in-place bored pile. During the process of lowering the plumb bob assembly 11 from the center of the hole of the to-be-measured cast-in-place bored pile to the bottom of the hole, the plumb bob assembly 11 drives the measuring rope 121 to extend out of the measuring rope mechanism 12, and the length sensor 13 will measure the length data of the measuring rope 121 extending out of the measuring rope mechanism 12 in real time and upload it to the background terminal 2. The background terminal 2 obtains the length data measured by the length sensor 13 when the plumb bob assembly 11 is lowered to the bottom of the hole of the to-be-measured cast-in-place bored pile as the first measurement data. Calculating the sum of the first measurement data and the height of the plumb bob assembly 11 can obtain the currently measured hole depth of the to-be-measured cast-in-place bored pile, that is, the first measurement data plus the height of the plumb bob assembly 11 is equal to the hole depth. Among them, the height of the plumb bob assembly 11 can be pre-stored in the background terminal 2 by relevant personnel, or can be input by the operator through the user terminal 3 and uploaded to the background terminal 2, and no specific limitation is made here. In addition, after the operator views the hole depth sent by the background terminal 2 on the user terminal 3, the operator can retract the measuring rope 121 into the measuring rope mechanism 12 to facilitate subsequent measurement of the sediment thickness of the to-be-measured cast-in-place bored pile.

[0043] When the background terminal 2 determines that the obtained hole depth is within the preset hole depth range, it indicates that the hole depth of the bored cast-in-place pile to be measured meets the design requirements. Then, when the operator measures the sediment thickness of the bored cast-in-place pile to be measured, the operator can start the length sensor 13 and the density sensor 14 simultaneously, and slowly lower the weight assembly 11 from the center of the hole of the bored cast-in-place pile to be measured again. During the process of lowering the weight assembly 11 from the center of the hole of the bored cast-in-place pile to be measured again, the length sensor 13 will measure the length data of the measuring rope 121 extending from the measuring rope mechanism 12 in real time and upload it to the background terminal 2. At the same time, the density sensor 14 will measure the density data of the liquid inside the hole of the bored cast-in-place pile to be measured in real time and upload it to the background terminal 2. The background terminal 2 will monitor in real time whether the density data uploaded by the density sensor 14 changes. Since the upper part of the sediment in the bored cast-in-place pile is the prepared slurry, the density of the slurry in the upper part of the sediment is basically the same. However, when it comes to the sediment part, because most of the sediment is particulate matter, the density will change greatly. The interface between the slurry and the sediment can be determined by monitoring whether the density data uploaded by the density sensor 14 changes. When the background terminal 2 monitors that the density data uploaded by the sensor changes, it indicates that the weight assembly 11 has dropped to the interface between the slurry and the sediment. Record the length data measured by the length sensor 13 at this time as the second measurement data, and calculate the difference between the first measurement data and the second measurement data to obtain the sediment thickness of the bored cast-in-place pile to be measured, that is, the first measurement data minus the second measurement data equals the sediment thickness.

[0044] The intelligent measuring system for the hole depth and sediment thickness of bored cast-in-place piles provided by the embodiments of the present invention can automatically obtain the hole depth and sediment thickness of bored cast-in-place piles based on the length data measured by the length sensor 13 and the density data measured by the density sensor 14. It does not need to rely on the sense of touch to judge the interface between the sediment and the slurry, and does not need to manually read the measurement data, making the measured data more accurate, ensuring the quality during the pile foundation construction process. At the same time, the measurement efficiency is high, which can significantly improve the construction efficiency of bored cast-in-place piles and make the construction more industrialized, green and intelligent. Moreover, by intelligently obtaining the measurement data through the length sensor 13 and the density sensor 14 and uploading it to the background terminal 2, the intelligent management level of pile foundation construction is improved, and the authenticity of the data throughout the process is ensured. Relevant personnel such as construction personnel and supervisors can view the data in the background, simplifying the acceptance process. At the same time, technical experts can view the real-time measured data through the background terminal 2 for remote guidance.

[0045] In a more specific embodiment, the weight assembly 11 includes a connecting block 111 and a cone 112; the connecting block 111 is arranged at the top of the cone 112, the top of the connecting block 111 is connected to the measuring rope 121, and the density sensor 14 is arranged on the side wall of the connecting block 111.

[0050] In this embodiment, referring to Figure 2 , a second fixing ring 114 for fixing the density sensor 14 is disposed on the side wall of the connecting block 111, so that the density sensor 14 is installed between the second fixing ring 114 and the side wall of the connecting block 111. Preferably, the first fixing ring 113 is a U-shaped ring.

[0051] In a more specific embodiment, the connecting block 111 is of a cuboid structure, the length of the connecting block 111 is equal to the width of the connecting block 111, the value range of the length of the connecting block 111 is [10 cm, 15 cm], and the value range of the height of the connecting block 111 is [3 cm, 5 cm].

[0052] In this embodiment, referring to Figure 2 and Figure 3, the connecting block 111 is in a cuboid structure, and the length of the connecting block 111 is equal to the width of the connecting block 111, that is, the cross-section of the connecting block 111 is square.

[0055] An intelligent measuring system for the hole depth and sediment thickness of bored cast-in-place piles provided by an embodiment of the present invention can automatically obtain the hole depth and sediment thickness of bored cast-in-place piles based on the length data measured by the length sensor and the density data measured by the density sensor, improving the efficiency of measuring the hole depth and sediment thickness of bored cast-in-place piles, and the measured data is accurate, making the construction more industrialized, green and intelligent.

[0056] As Figure 4 shown, Figure 4 is a schematic flow chart of a construction method based on an intelligent measuring system for the hole depth and sediment thickness of bored cast-in-place piles provided by an embodiment of the present invention. An embodiment of the present invention also provides a construction method based on the intelligent measuring system for the hole depth and sediment thickness of bored cast-in-place piles described in any of the foregoing embodiments, and this construction method includes steps S11 to S19.

[0057] S11. Start the length sensor and lower the weight assembly from the center of the hole of the bored cast-in-place pile to be measured.

[0058] In this embodiment, when the operator needs to measure the hole depth of the bored cast-in-place pile to be measured, the operator can start the length sensor and at the same time slowly lower the weight assembly from the center of the hole of the bored cast-in-place pile to be measured until the weight assembly is lowered to the bottom of the hole of the bored cast-in-place pile to be measured.

[0059] S12. When the weight assembly is lowered from the center of the hole of the bored cast-in-place pile to be measured, the length sensor measures the length data of the measuring rope extending from the measuring rope mechanism in real time and uploads it to the background terminal.

[0060] In this embodiment, during the process of lowering the weight assembly from the center of the formed hole of the bored cast-in-place pile to be measured to the bottom of the hole, the weight assembly drives the measuring rope to extend out from the measuring rope mechanism, and the length sensor will measure the length data of the measuring rope extending out from the measuring rope mechanism in real time and upload it to the background terminal.

[0061] S13. The background terminal obtains the first measurement data based on the length data uploaded by the length sensor, and obtains the formed hole depth according to the first measurement data and the height of the weight assembly; wherein, the first measurement data is the length data measured by the length sensor when the weight assembly is lowered from the center of the formed hole of the bored cast-in-place pile to be measured to the bottom of the hole.

[0062] In this embodiment, the background terminal obtains the length data measured by the length sensor when the weight assembly is lowered to the bottom of the bored cast-in-place pile to be measured as the first measurement data, and calculates the sum of the first measurement data and the height of the weight assembly to obtain the currently measured formed hole depth of the bored cast-in-place pile to be measured, that is, the first measurement data plus the height of the weight assembly is equal to the formed hole depth. Among them, the height of the weight assembly can be pre-stored in the background terminal by relevant personnel, or can be input by the operator through the user terminal and uploaded to the background terminal, which is not specifically limited here. In addition, after the operator views the formed hole depth sent by the background terminal on the user terminal, the measuring rope can be recovered into the measuring rope mechanism to facilitate the subsequent measurement of the sediment thickness of the bored cast-in-place pile to be measured.

[0063] In one embodiment, after step S13, it further includes:

[0064] If the background terminal determines that the formed hole depth is not within the preset hole depth range, it generates a result that the hole depth does not meet the standard, and sends the formed hole depth and the result that the hole depth does not meet the standard to the user terminal.

[0065] In this embodiment, when the background terminal determines that the obtained formed hole depth is not within the preset hole depth range, it means that the formed hole depth of the bored cast-in-place pile to be measured has not yet reached the design requirement. The background terminal then generates a result that the hole depth does not meet the standard, and sends the formed hole depth and the result that the hole depth does not meet the standard to the user terminal. The operator can view the formed hole depth and the result that the hole depth does not meet the standard through the user terminal, and then can notify the construction site that the hole opening operation needs to continue. After completing the corresponding hole opening construction, it is necessary to return to execute step S11 until the formed hole depth meets the design requirement. Further, after the background terminal generates the result that the hole depth does not meet the standard, it can also generate hole opening construction plan information according to the formed hole depth, the preset hole depth range and the preset hole opening recommendation strategy. Among them, the hole opening construction plan information can include information such as construction depth and construction operations, so that the operator can perform corresponding construction according to the hole opening construction plan information, so as to quickly make the formed hole depth of the bored cast-in-place pile to be measured meet the design requirement and quickly complete the hole opening operation.

[0066] S14. If the background terminal determines that the hole depth is within the preset hole depth range, it generates a hole depth compliance result and sends the hole depth and the hole depth compliance result to the user terminal.

[0067] In this embodiment, when the background terminal determines that the obtained hole depth is within the preset hole depth range, it indicates that the hole depth of the to-be-tested bored cast-in-place pile meets the design requirements. The background terminal then generates a hole depth compliance result and sends the hole depth and the hole depth compliance result to the user terminal to notify the operator that the hole depth of the current to-be-tested bored cast-in-place pile meets the design requirements and subsequent measurement operations for the sediment thickness of the to-be-tested bored cast-in-place pile can be carried out.

[0068] S15. Start the length sensor and the density sensor, and lower the weight assembly again from the center of the hole of the to-be-tested bored cast-in-place pile.

[0069] S16. When the weight assembly is lowered again from the center of the hole of the to-be-tested bored cast-in-place pile, the length sensor measures the length data of the measuring rope extending from the measuring rope mechanism in real time and uploads it to the background terminal.

[0070] S17. When the weight assembly is lowered again from the center of the hole of the to-be-tested bored cast-in-place pile, the density sensor measures the density data of the liquid inside the hole of the to-be-tested bored cast-in-place pile in real time and uploads it to the background terminal.

[0071] In this embodiment, when the operator measures the sediment thickness of the to-be-tested bored cast-in-place pile, the operator can start the length sensor and the density sensor simultaneously and slowly lower the weight assembly again from the center of the hole of the to-be-tested bored cast-in-place pile. During the process of the weight assembly being lowered again from the center of the hole of the to-be-tested bored cast-in-place pile, the length sensor measures the length data of the measuring rope extending from the measuring rope mechanism in real time and uploads it to the background terminal, and at the same time, the density sensor measures the density data of the liquid inside the hole of the to-be-tested bored cast-in-place pile in real time and uploads it to the background terminal.

[0072] S18. The background terminal obtains second measurement data based on the length data uploaded by the length sensor and the density data uploaded by the density sensor, and obtains the sediment thickness according to the first measurement data and the second measurement data; wherein, the second measurement data is the length data measured by the length sensor when the density data measured by the density sensor changes.

[0073] S19. The user terminal receives the sediment thickness sent by the background terminal.

[0074] In this embodiment, during the process of measuring the sediment thickness of the bored cast-in-place pile to be measured, the background terminal will monitor in real time whether the density data uploaded by the density sensor changes. Since the upper part of the sediment in the bored cast-in-place pile to be measured is the prepared slurry, the density of the slurry in the upper part of the sediment is basically the same. However, when it comes to the sediment part, because most of the sediment is particulate matter, the density will change greatly. The interface between the slurry and the sediment can be determined by monitoring whether the density data uploaded by the density sensor changes. When the background terminal monitors that the density data uploaded by the sensor changes, it means that the heavy hammer assembly has dropped to the interface between the slurry and the sediment. Record the length data measured by the length sensor at this time and use it as the second measurement data. Calculate the difference between the first measurement data and the second measurement data to obtain the sediment thickness of the bored cast-in-place pile to be measured, that is, the first measurement data minus the second measurement data equals the sediment thickness. When the background terminal obtains the sediment thickness, it will send the sediment thickness to the user terminal, and the user terminal receives the sediment thickness sent by the background terminal so that the operator can view the current sediment thickness of the bored cast-in-place pile to be measured.

[0075] In one embodiment, after step S18, it further includes:

[0076] The background terminal determines whether the sediment thickness is within a preset thickness range;

[0077] If the background terminal determines that the sediment thickness is within the preset thickness range, it generates a sediment compliance result and sends the sediment compliance result to the user terminal.

[0078] In this embodiment, when the background terminal obtains the sediment thickness, it will determine whether the sediment thickness is within a preset thickness range to judge whether the sediment thickness meets the design requirements. If the background terminal determines that the sediment thickness is within the preset thickness range, it means that the sediment thickness has met the design requirements, then it generates a sediment compliance result and sends it to the user terminal to notify the operator that the current sediment thickness has met the design requirements.

[0079] In one embodiment, after the step where the background terminal determines whether the sediment thickness is within a preset thickness range, it further includes:

[0080] If the background terminal determines that the sediment thickness is not within the preset thickness range, it generates a sediment over-thickness result and sends the sediment over-thickness result to the user terminal.

[0081] In this embodiment, if the background terminal determines that the sediment thickness is not within the preset thickness range, indicating that the sediment thickness does not meet the design requirements, it generates a result of excessive sediment thickness and sends it to the user terminal. The operator can view the result of excessive sediment thickness through the user terminal, notify the construction site to continue the hole cleaning operation, and after completing the corresponding hole cleaning construction, it is necessary to return to execute step S15 until the sediment thickness meets the design requirements. Further, after generating the result of excessive sediment thickness, the background terminal can also generate hole cleaning construction plan information according to the sediment thickness, the preset thickness range, and the preset hole cleaning recommendation strategy. Among them, the hole cleaning construction plan information can include information such as the sediment cleaning thickness and hole cleaning operation, so that the operator can perform corresponding construction according to the hole cleaning construction plan information, thereby quickly making the sediment thickness of the bored cast-in-place pile to be measured meet the design requirements and quickly completing the hole cleaning operation.

[0082] The construction method provided by the embodiment of the present invention based on the intelligent measurement system for the hole depth and sediment thickness of the bored cast-in-place pile described in any one of the foregoing embodiments can automatically obtain the hole depth and sediment thickness of the bored cast-in-place pile based on the length data measured by the length sensor and the density data measured by the density sensor, improving the efficiency of measuring the hole depth and sediment thickness of the bored cast-in-place pile, and the measurement data is accurate, making the construction more industrialized, green and intelligent.

Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention.
