Description

Technical Field

[0001] The invention relates to the technical field, and in particular to a pile driver construction monitoring system based on a pile head. Background Art

[0002] In existing construction projects, pile drivers are usually used for drilling and piling operations. Pile drivers usually include a fixed bracket and a pile head that can move up and down. According to the type of pile foundation, pile drivers can be divided into: prefabricated pile drivers, which are used to drive prefabricated pile foundations into the ground, including concrete piles, steel piles, etc., which are suitable for medium and large foundation projects; cast-in-place pile drivers or rotary drilling pile drivers, which are used to cast pile foundations on site, including rotary drilling rigs, impact drilling rigs, etc., which are suitable for various types of foundation projects.

[0003] The full-rotation and full-casing construction method is called the SUPERTOP method in Japan. Steel casing is used to protect the wall during the drilling process. It has the characteristics of good pile quality, no mud pollution, green environmental protection, and reduced concrete filling coefficient. The full-rotation drilling rig has strong torque, pressing force and cutter head, which can complete the construction tasks in hard rock formations. During the bored pile construction process, different types and diameters of pile foundation holes can be constructed according to different geological conditions and design requirements. However, in the prior art, when the full-rotation drilling rig using the full-rotation and full-casing construction is used as a pile driver for construction, most of the pile heads that are being drilled are lacking in monitoring during the construction process, making it difficult to make corresponding judgments on the working scenes of the pile heads, and thus it is difficult to make corresponding adjustments to the operating power of the pile driver in time in the corresponding rock layer, thereby reducing its overall work efficiency. Summary of the invention

[0004] To this end, the present invention provides a pile driver construction monitoring system based on a pile head, so as to overcome the problem in the prior art that it is difficult to adjust the construction status of the pile driver in real time according to the actual working scene of the pile head.

[0005] To achieve the above object, the present invention provides a pile driver construction monitoring system based on a pile head, comprising:

[0006] A height detection module is used to monitor the real-time descending height of the pile head during the descending process and send an operation stop message when the real-time descending height reaches a preset drilling height;

[0007] A verticality detection module is used to monitor the verticality of the descending pile head and send first detection information when the pile head deviates;

[0008] A power detection module, used for monitoring the actual operating power of the pile driver in operation, determining the actual operating power according to the first operating power, and sending second detection information to the outside when the actual operating power is greater than the first operating power;

[0009] a central monitoring module, which is connected to the height detection module, the verticality detection module and the power detection module respectively, and is used to determine the real-time descent height of the pile head at the time of the first detection information and the second detection information according to a preset correction height and a preset conversion height, so as to determine subsequent early warning measures or adjustment measures;

[0010] A real-time warning module, which is connected to the central monitoring module and the height detection module, and is used to send corresponding warning information and alarm according to the determination result;

[0011] The power adjustment module is connected to the central monitoring module and the power detection module, and is used to adjust or correct the actual operating power of the pile driver according to the determination result.

[0012] Furthermore, the height detection module includes:

[0013] A height acquisition unit is used to detect the real-time descent height of the pile head in operation to obtain its actual descent height;

[0014] The fourth height determination unit has the preset drilling height arranged therein, and is connected to the height acquisition unit to determine the actual descent height according to the preset drilling height.

[0015] Furthermore, a preset vertical deviation is provided in the verticality detection module, the verticality of the descending pile head is compared with the preset verticality, and the first detection information is sent when the verticality of the pile head is greater than or equal to the preset verticality.

[0016] Furthermore, the central monitoring module includes a first height determination unit. When the central monitoring module receives the first detection information, the actual descent height of the pile head at the time of the first detection information is obtained as the first determination height, and the first determination height is determined by the first height determination unit according to the preset corrected height.

[0017] Furthermore, the first height determination unit determines the first determination height by:

[0018] If the first determined height is less than or equal to the preset correction height, it will be determined as a shallow deviation, and the first warning information will be sent out through the real-time warning module to alarm;

[0019] If the first determined height is greater than the preset correction height, it will be determined as a deep deviation, and a second warning message will be sent out through the real-time warning module to sound an alarm.

[0020] Furthermore, the central monitoring module also includes a second height determination unit. When the central monitoring module receives the second detection information, the actual descent height of the pile head at the time of the second detection information is obtained as the second determination height, and the second determination height is determined by the second height determination unit according to a preset transformation height.

[0021] Further, the second height determination unit determines the second determination height by:

[0022] If the second determined height is greater than or equal to the preset conversion height, the power adjustment module is used to control the pile driver to adjust in a first adjustment manner;

[0023] If the second determination height is less than the preset transformation height, a calculation is performed based on the second determination height and the preset transformation height to obtain a difference between the preset transformation height and the second determination height as the determination height difference.

[0024] Further, the central monitoring module further comprises a third height determination unit, a preset height difference is set in the third height determination unit, and the third height determination unit determines the determined height difference according to the preset height difference;

[0025] If the determined height difference is less than or equal to the preset height difference, the pile driver is controlled by the power adjustment module to be adjusted in a first adjustment mode;

[0026] If the determined height difference is greater than the preset height difference, the power adjustment module will be used to control the pile driver to adjust in a second adjustment manner.

[0027] Furthermore, the first adjustment method is to control the pile driver to operate at a second operating power through the power adjustment module;

[0028] The second adjustment mode is to control the pile driver to run at the second operating power for a first preset adjustment period through the power adjustment module, and then control the pile driver to continue running at the first operating power.

[0029] Furthermore, the central monitoring module further includes an adjustment determination unit, in which a second preset adjustment period and a preset operating height are provided. The adjustment determination unit can obtain the descending height of the pile head in any second preset adjustment period as the actual operating height through the height detection module, and compare the actual operating height with the preset operating height through the adjustment determination unit;

[0030] If the actual operating height is greater than or equal to the preset operating height, no adjustment is required;

[0031] If the actual operating height is less than the preset operating height, the second operating power is corrected by calculating the preset operating height and the actual operating height;

[0032] Among them, P2′=[1+(hy-hs) / hy]×P2, P2′ is the corrected second operating power, hy is the preset operating altitude, hs is the actual operating altitude, and P2 is the second operating power.

[0033] Compared with the prior art, the beneficial effects of the present invention lie in that the real-time descent height of the descending pile head is acquired and monitored by the height detection module, which provides a data basis for subsequent judgment and enables the outside world to stop related operations in time when the pile head reaches the preset drilling height; the verticality detection module is used to detect the verticality of the pile head in the operation process in real time to avoid deviations during the operation as much as possible, and to issue an early warning in time when deviations occur to assist relevant personnel to correct them; the real-time operating power of the pile driver in the operation process is monitored by the power detection module, so that the system can acquire the operating status of the pile head according to the operating power of the pile driver in time, and analyze its actual working scene according to the central monitoring module, so as to make corresponding adjustments or corrections to the actual operating power of the pile driver, so that while meeting the power required by the current scene of the pile head, the resource allocation is more reasonable, thereby improving its overall work efficiency.

[0034] Furthermore, real-time monitoring and timely feedback mechanisms ensure that the drilling depth of the pile head can be effectively controlled, preventing safety accidents that may be caused by improper depth control. By precisely controlling the drilling depth of the pile head, material waste and additional costs caused by excessive drilling are avoided, which helps to reduce construction costs.

[0035] In particular, real-time warning and response are achieved through the preset vertical deviation. When the verticality deviation of the pile head reaches the preset value, the corresponding warning information is sent in time to remind the operator to take corresponding measures, so as to reduce the additional construction costs caused by the pile head deviation, such as rework and material waste.

[0036] Furthermore, by sending corresponding warning information according to different judgment results through the first height judgment unit, the system can quickly determine whether correction is needed and the correction method when correction is needed, thereby avoiding excessive or unnecessary correction operations and improving correction efficiency.

[0037] In particular, the actual descent height of the pile head when the power is increased is determined by the second height determination unit, so that the power of the pile driver can be dynamically adjusted according to the working scene of the pile head. The system can intelligently recommend adjustment measures based on the difference between the second determination height and the preset transformation height, thereby assisting operators to make more appropriate decisions and optimizing the construction process.

[0038] Furthermore, the operating power can be reasonably adjusted through corresponding adjustment methods to ensure that the pile head can be constructed with appropriate power under different geological conditions, improve the construction quality of the pile foundation, avoid pile driver overload caused by changes in geological hardness, reduce mechanical wear, and extend equipment service life.

[0039] In particular, through the setting of the third height determination unit and the preset height difference, the system can adopt different power adjustment strategies according to the distance between the pile head and the preset transformation height to achieve refined management;

[0040] Furthermore, the second operating power is dynamically corrected by adjusting the determination unit according to the comparison result between the actual operating height and the preset operating height, so as to ensure that the operating power of the pile driver can meet the working requirements of the pile head.

[0049] See also Figure 1 , which is a system framework diagram of a pile driver construction monitoring system based on a pile head in this embodiment;

[0050] Specifically, this embodiment provides a pile driver construction monitoring system based on a pile head, the system comprising:

[0051] A height detection module is used to monitor the real-time descending height of the pile head during the descending process, and to send an operation stop message when the real-time descending height reaches a preset drilling height;

[0052] A verticality detection module is used to monitor the verticality of the descending pile head and send first detection information when the pile head deviates;

[0053] A power detection module, used for monitoring the actual operating power of the pile driver in operation, determining the actual operating power according to the first operating power, and sending second detection information to the outside when the actual operating power is greater than the first operating power;

[0054] a central monitoring module, which is connected to the height detection module, the verticality detection module and the power detection module respectively, and is used to determine the real-time descent height of the pile head at the time of the first detection information and the second detection information according to a preset correction height and a preset conversion height, so as to determine subsequent early warning measures or adjustment measures;

[0055] A real-time warning module, which is connected to the central monitoring module and the height detection module, and is used to send corresponding warning information and alarm according to the determination result;

[0056] The power adjustment module is connected to the central monitoring module and the power detection module, and is used to adjust or correct the actual operating power of the pile driver according to the determination result.

[0057] The height detection module is used to obtain and monitor the real-time descent height of the descending pile head, which provides a data basis for subsequent judgment and enables the outside world to stop related operations in time when the pile reaches the preset drilling height; the verticality detection module is used to detect the verticality of the pile head in real time during operation to avoid deviations as much as possible, and to issue timely warnings when deviations occur to assist relevant personnel to correct them; the power detection module is used to monitor the real-time operating power of the pile driver during operation, so that the system can obtain the operating status of the pile head according to the operating power of the pile driver in time, and analyze its actual working scene according to the central monitoring module to make corresponding adjustments or corrections to the actual operating power of the pile driver, so that it can meet the power required by the current scene of the pile head while making resource allocation more reasonable, thereby improving its overall work efficiency.

[0058] Specifically, the height detection module includes:

[0059] A height acquisition unit is used to detect the real-time descent height of the pile head in operation to obtain its actual descent height;

[0060] The fourth height determination unit has the preset drilling height arranged therein, and is connected to the height acquisition unit to determine the actual descent height according to the preset drilling height.

[0061] The preset drilling height is the required bored pile depth determined according to engineering requirements, and the height acquisition unit may be a non-contact depth detection device with ultrasonic or radar detection elements.

[0062] Real-time monitoring and timely feedback mechanisms ensure that the drilling depth of the pile head can be effectively controlled, preventing safety accidents that may be caused by improper depth control. By precisely controlling the drilling depth of the pile head, material waste and additional costs caused by excessive drilling are avoided, which helps to reduce construction costs.

[0063] Specifically, a preset vertical deviation is set in the verticality detection module, the verticality of the descending pile head is compared with the preset verticality, and the first detection information is sent when the verticality of the pile head is greater than or equal to the preset verticality.

[0064] The preset verticality should be selected and set according to the required pile length of the bored pile foundation. According to the search, in general bored pile foundation operations, the vertical inclination requirement of bored piles is that the inclination does not exceed 1% of the hole depth and is not greater than 500 mm. If the pile length is 40 meters, the maximum vertical deviation allowed is 0.4 meters. The verticality deviation percentage is converted into an angle by trigonometric calculation.

[0065] in, If we substitute the pile length of 40 meters and the vertical deviation of 0.4 meters, we get

[0066] Real-time warning and response are achieved through the preset vertical deviation. When the verticality deviation of the pile head reaches the preset value, the corresponding warning information is sent in time to remind the operator to take corresponding measures to reduce the additional construction costs caused by the pile head deviation, such as rework and material waste.

[0067] Please continue reading Figure 2 and Figure 3 ,in, Figure 2 This is a structural framework diagram of the central monitoring module of this embodiment. Figure 3 This is a logic diagram for determining the subsequent warning mode by the central monitoring module of this embodiment;

[0068] Specifically, the central monitoring module includes a first height determination unit. When the central monitoring module receives the first detection information, the actual descent height of the pile head at the time of the first detection information is obtained as the first determination height, and the first determination height is determined by the first height determination unit according to the preset correction height.

[0069] That is, when the verticality detection module detects that a pile head in operation has deviated, the first height determination unit arranged in the central monitoring module will be used to determine the actual descent height of the pile head under the current circumstances when the deviation occurs, so as to determine whether it can be directly corrected by equipment such as a pile grinder, and to send corresponding early warning information based on the determined result to remind relevant external personnel to promptly take corresponding measures to correct the deviation.

[0070] Specifically, the process of determining the first determination height by the first height determination unit includes:

[0071] If the first determined height is less than or equal to the preset correction height, it will be determined as a shallow deviation, and the first warning information will be sent out through the real-time warning module to alarm;

[0072] If the first determined height is greater than the preset correction height, it will be determined as a deep deviation, and a second warning message will be sent out through the real-time warning module to sound an alarm.

[0073] The preset correction height is the drilling depth that can be directly corrected by a pile grinder or other equipment during normal construction. For general grouting projects, the height that can be directly corrected by a pile grinder or other equipment generally does not exceed 5m, so the maximum value of the preset correction height should not exceed 5m.

[0074] That is, when the first determined height is less than or equal to the preset correction height, it means that the actual descending height of the pile head when the current deviation occurs is still within the height that can be directly corrected by using equipment such as a pile grinder, so it is determined that the deviation occurs in the shallow layer, and relevant warning information is sent out to notify relevant personnel to use equipment such as a pile grinder to correct the deviation in time;

[0075] When the first determination height is greater than the preset correction height, it means that the actual descending height of the pile head at the time of the current deviation has exceeded the height that can be directly corrected by equipment such as a pile grinder, so it is determined that the deviation occurs at a deeper layer, and relevant warning information needs to be sent out in time to notify relevant personnel to perform corresponding correction operations;

[0076] Among them, when a full-rotation drilling rig with full-rotation and full-casing construction is used as a pile driver for construction, the correction operation made in response to the second warning information can be backfilling sand or clay into the hole, and simultaneously pulling up the pile head casing while filling the soil, until the pile head is lifted to the place where it passed the last inspection, and then the pile head is straightened, and its verticality is checked before re-pressing the drill.

[0077] By sending corresponding warning information according to different judgment results through the first height judgment unit, the system can quickly determine whether correction is needed and the correction method when correction is needed, avoiding excessive or unnecessary correction operations and improving correction efficiency.

[0078] Please continue reading Figure 4 , which is a logic diagram for determining the subsequent adjustment method of the central monitoring module in this embodiment;

[0079] Specifically, the central monitoring module also includes a second height determination unit. When the central monitoring module receives the second detection information, the actual descent height of the pile head at the time of the second detection information is obtained as the second determination height, and the second determination height is determined by the second height determination unit according to the preset transformation height.

[0080] That is, when the power detection module detects that the actual operating power of the running pile driver suddenly increases, the actual descending height of the pile head when the power increases will be determined by the second height determination unit arranged in the central monitoring module to determine whether it has actually reached the preset power conversion height, so as to make corresponding adjustment measures in time according to the determined result, so that the operating power of the pile driver can match the working scene of the pile head and improve its working efficiency.

[0081] Specifically, the determination process of the second determination height by the second height determination unit includes:

[0082] If the second determined height is greater than or equal to the preset conversion height, the power adjustment module is used to control the pile driver to adjust in a first adjustment manner;

[0083] If the second determination height is less than the preset transformation height, a calculation is performed based on the second determination height and the preset transformation height to obtain a difference between the preset transformation height and the second determination height as the determination height difference.

[0084] That is, when the second determination height is greater than or equal to the preset conversion height, it means that the actual descending height of the pile head under the current situation when the power is increased has reached the preset power conversion height, that is, the reason for the increase in power at this time is that the actual working scene of the pile head has changed from the soft soil layer to the hard soil layer, and the actual operating power of the pile driver should be changed accordingly to match it with the actual working scene of the pile head;

[0085] When the second judgment height is less than the preset conversion height, it means that the actual descent height of the pile head when the power is increased in the current situation has reached the preset power conversion height, which means that the actual descent height of the pile head when the power is increased in the current situation has not reached the preset descent height when the power is converted, which means that it may encounter certain obstacles in the current working scenario, and its operating power should be appropriately adjusted to assist the pile head to pass through the current obstacle layer as soon as possible, and by comparing the difference between its distance and the preset conversion height, its specific adjustment measures should be determined.

[0086] The actual descent height of the pile head when the power is increased is determined by the second height determination unit, so that the power of the pile driver can be dynamically adjusted according to the working scene of the pile head. The system can intelligently recommend adjustment measures based on the difference between the second determination height and the preset transformation height, assisting operators to make more appropriate decisions, thereby optimizing the construction process.

[0087] Specifically, the central monitoring module further includes a third height determination unit, in which a preset height difference is set, and the third height determination unit determines the determined height difference according to the preset height difference;

[0088] If the determined height difference is less than or equal to the preset height difference, the pile driver is controlled by the power adjustment module to be adjusted in a first adjustment mode;

[0089] If the determined height difference is greater than the preset height difference, the power adjustment module will be used to control the pile driver to adjust in a second adjustment manner.

[0090] The preset height difference should be selected according to the first preset adjustment period, and its maximum value should not exceed the distance that the pile head can travel after running at the second preset operating power for the preset first preset adjustment period. The first preset adjustment period should be selected according to the actual drilling speed of the pile head. Generally speaking, in order to make the determination more accurate, the duration of the selected first preset period should be selected between the time required for the pile head to actually drop by 0.5 meters to 1 meter.

[0091] That is, when it is determined that the height difference is less than or equal to the preset height difference, it means that the distance between the pile head and the preset change height is less than the distance traveled by the pile head after the first preset adjustment cycle is run at the second operating power. In order to avoid repeated replacement, it can be directly adjusted in the second adjustment mode;

[0092] When it is determined that the height difference is greater than the preset height difference, it means that the distance between the pile head and the preset change height is still greater than the travel distance of the pile head after running the first preset adjustment cycle at the second operating power. Whether the pile head has passed through the obstacle layer can be determined by judging whether the actual operating power of the pile driver after running the first preset cycle at the second operating power is still greater than the first operating power. If it is still greater than the first operating power, it means that the obstacle layer has not been passed through. The first detection information will be sent again through the power detection unit for judgment and adjustment in the next cycle. If it passes, no subsequent adjustment is required to assist the pile head to pass through the obstacle layer as quickly as possible while reducing the waste of resources, so that the system can adaptively adjust the operating power of the pile driver according to the actual construction situation, optimize resource allocation, and improve energy utilization efficiency.

[0093] Specifically, the first adjustment method is to control the pile driver to operate at a second operating power through the power adjustment module;

[0094] The second adjustment mode is to control the pile driver to run at the second operating power for a first preset adjustment period through the power adjustment module, and then control the pile driver to continue running at the first operating power.

[0095] Among them, the first operating power, the second operating power and the preset transformation height should all be selected according to the possible working scene of the pile head detected before the start of construction in the current construction site. It can be divided into soft soil layer and hard soil layer in the general direction. In actual work, it can be selected and set accordingly according to the actual distribution of rock layers detected. The first operating power is the operating power that the pile driver should have when the pile head is working in the soft soil layer, and the second operating power is the operating power that the pile driver should have when the pile head is working in the hard soil layer. The preset transformation height is the height at which the pile head reaches the hard soil layer from the soft soil layer.

[0096] The operating power can be reasonably adjusted through corresponding adjustment methods to ensure that the pile head can be constructed with appropriate power under different geological conditions, improve the construction quality of the pile foundation, avoid pile driver overload caused by changes in geological hardness, reduce mechanical wear and extend equipment service life.

[0097] Specifically, the central monitoring module also includes an adjustment determination unit, in which a second preset adjustment period and a preset operating height are set. The adjustment determination unit can obtain the height of the pile head falling in any second preset adjustment period as the actual operating height through the height detection module, and compare the actual operating height with the preset operating height through the adjustment determination unit;

[0098] If the actual operating height is greater than or equal to the preset operating height, no adjustment is required;

[0099] If the actual operating height is less than the preset operating height, the second operating power is corrected by calculating the preset operating height and the actual operating height;

[0100] Among them, P2′=[1+(hy-hs) / hy]×P2, P2′ is the corrected second operating power, hy is the preset operating altitude, hs is the actual operating altitude, and P2 is the second operating power.

[0101] Wherein, the second preset adjustment period should not be less than the first preset adjustment period, and the preset operating height is the distance that the pile head can travel after running at the second preset operating power for the second preset adjustment period under normal circumstances;

[0102] That is, when the actual operating height is greater than or equal to the preset operating height, it means that the distance traveled by the pile head after running the second preset adjustment period at the current operating power meets the normal travel distance, so it means that the current power can meet its working requirements, and there is no need to adjust the actual operating power of the pile driver;

[0103] When the actual operating height is less than the preset operating height, it means that the distance traveled by the pile head after running the second preset adjustment cycle at the current operating power cannot meet the travel distance it should have under normal circumstances, that is, the current operating power of the pile driver cannot meet the working requirements of the pile head, and the actual operating power of the pile driver needs to be corrected so that it can meet the working requirements of the pile head.

[0104] By setting the third height determination unit and the preset height difference, the system can adopt different power adjustment strategies according to the distance between the pile head and the preset change height to achieve refined management; and by adjusting the determination unit according to the comparison result between the actual operating height and the preset operating height, the second operating power is dynamically corrected to ensure that the pile driver operating power can meet the pile head working requirements.
