Description

Technical Field

[0001] This invention relates to the field of dynamic compaction construction monitoring, specifically to an automatic monitoring system and method for the number of compaction blows and compaction energy during dynamic compaction construction. Background Technology

[0002] Dynamic compaction is a foundation treatment method that uses the enormous impact energy and vibration waves generated when a heavy hammer falls freely from a height to forcefully compact the foundation soil. As a classic and cost-effective foundation treatment technology, dynamic compaction has become one of the most commonly used and economical foundation treatment methods in geotechnical engineering due to its outstanding advantages of significantly improving the bearing capacity of the foundation, accelerating soil consolidation, and effectively eliminating post-construction settlement.

[0003] Currently, in large-scale dynamic compaction construction, relying on manual supervision to ensure that thousands of compaction points are not missed and that each blow reaches the designed energy is virtually impossible. This leads to issues such as "missed compaction," "under-compaction," and "reduced compaction energy (drop height)," directly resulting in weak points in subsequent foundation treatment. Furthermore, manually controlling the drop height and recording the number of blows introduces significant subjectivity and error, making it prone to clerical mistakes, memory biases, and even the risk of retroactive recording and data tampering. This greatly diminishes the reliability of construction records as acceptance criteria. If quality problems such as uneven foundation settlement or building cracking occur later in the project, the lack of objective, continuous, and traceable original data makes it difficult to accurately pinpoint the root cause, leading to difficulties in determining responsibility and frequent disputes. To ensure project quality, owners and supervisors often invest a lot of manpower in "full-process on-site supervision," but the effect is limited and the labor cost is high. Projects often require secondary treatment of the foundation after dynamic compaction and reinforcement of the superstructure. This not only eliminates the original cost advantage, but also causes serious economic losses such as delays in construction period and significant increases in investment, and may even affect structural safety. Summary of the Invention

[0004] To address the problems mentioned in the prior art, this invention proposes an automatic monitoring system and method for the number of impacts and impact energy in dynamic compaction construction. The automatic monitoring system monitors and receives parameter information and construction feedback information during the construction process, improving supervision. The monitored parameters include impact point location, hammer drop height (impact energy), and number of impacts. This solves the problems of missed compaction, insufficient compaction, and reduced impact energy (drop distance) in the prior art, and also reduces the subjectivity and error of human supervision, avoiding the risk of clerical errors and data tampering, thus ensuring project quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This invention proposes an automatic monitoring system for the number of compaction blows and compaction energy during dynamic compaction construction, comprising: A data monitoring device is installed on the dynamic compaction machine and connected to the hammer. The data monitoring device includes a position monitoring module and a weight monitoring module, which are used to collect the position coordinates, elevation data and weight data of the compaction point. The cloud-based monitoring platform communicates with the data monitoring device to receive and process the location coordinates, elevation data, and weight data of the compaction points. The client terminal communicates with the cloud monitoring platform for remote monitoring and access to construction data; The cloud monitoring platform is configured as follows: The location coordinates are compared with preset location coordinates to determine the validity of the tamping point location; The drop height is calculated based on the preset impact energy and hammer weight, and the theoretical drop height is determined by combining the elevation data. The elevation data from the data monitoring device is compared with the theoretical drop hammer elevation in real time to determine the validity of the drop hammer height. The validity of the hammer weight is determined by comparing the weight data with the preset weight. When the tamping point location, hammer drop height, and hammer weight are all valid, the number of valid tamping blows is counted; otherwise, an alarm is triggered and the reason for invalidity is recorded. When the number of effective tamping blows reaches the preset value, a tamping completion signal is generated.

[0006] As a further improvement of the present invention, the data monitoring device is mounted on the unhooking device, which is used for detachable connection with the tamping hammer.

[0007] As a further improvement of the present invention, the location monitoring module includes a global navigation satellite system, a transmission module and an Internet of Things card, for real-time acquisition and transmission of location coordinates and elevation data; The weight monitoring module includes a tension sensor, which monitors the weight of the hammer and sends the data to a cloud monitoring platform.

[0008] As a further improvement of the present invention, the cloud monitoring platform also includes a data storage module for automatically recording data during the construction process, including the number of effective compaction blows, the number of ineffective compaction blows, and the reasons for alarms.

[0009] As a further improvement of the present invention, the client terminal includes a handheld terminal or a computer.

[0010] This invention proposes an automatic monitoring method for the number of compaction blows and compaction energy during dynamic compaction construction, applied to the aforementioned automatic monitoring system for the number of compaction blows and compaction energy during dynamic compaction construction, comprising the following steps: S1. After the dynamic compaction machine is in place, connect the data monitoring device to the hammer and use the data monitoring device to initially calibrate the position coordinates and elevation of the compaction point to obtain the calibrated coordinates and elevation. S2. Compare the calibrated coordinates with the coordinates of the preset position. If the error value is within the allowable range, the tamping point position is determined to be valid. S3. Based on the preset impact energy and hammer weight, calculate the hammer drop height and determine the theoretical hammer drop height by combining the calibrated elevation obtained by the data monitoring device. S4. During the tamping process, the position monitoring module monitors the elevation changes in real time and compares the real-time elevation with the theoretical hammer drop elevation. When they match, the hammer drop height is determined to be valid. At the same time, the weight monitoring module monitors the hammer weight in real time. When it matches the preset weight, the hammer weight is determined to be valid. S5. When the tamping point location, hammer drop height and hammer weight are all determined to be valid, count one valid tamping number; otherwise, count the invalid tamping number and trigger an alarm. S6. Repeat steps S4 to S5 until the effective number of tamping blows reaches the preset value, and determine that the tamping of the tamping point is completed.

[0011] As a further improvement to the present invention, the formula for calculating the theoretical drop height in S3 is as follows:

[0012] In the formula: E This refers to the single-point impact energy of dynamic compaction. M For hammer weight; g It is the acceleration due to gravity; h This represents the drop height of the hammer.

[0013] As a further improvement of the present invention, the alarm in S5 includes sending the recorded reason for ineffective impact to the client terminal.

[0014] As a further improvement of the present invention, the initial calibration in S1 includes correcting the position coordinates and elevation data to eliminate errors.

[0015] As a further improvement of the present invention, it also includes remote access to and monitoring of construction data through a client terminal, wherein the client terminal includes a handheld terminal or a computer, and receives real-time data through a cloud monitoring platform.

[0016] Compared with the prior art, the present invention achieves the following technical effects: This invention, through its client-side interface, cloud-based monitoring system platform, and data monitoring module, enables real-time monitoring of construction data. The system automatically records and identifies the location of compaction points, compaction energy, and the number of compactions, effectively avoiding problems caused by human factors such as missed compaction, insufficient compaction, and inadequate compaction energy during dynamic compaction construction, thus improving the reliability and controllability of the construction process. Furthermore, this invention receives and monitors the construction process via a handheld terminal, allowing for real-time remote viewing and analysis of the reasons for ineffective compaction through data recorded on the cloud-based monitoring system platform. This enables real-time rectification of deficiencies in the construction process, ensuring the quality of dynamic compaction construction. Simultaneously, the construction data automatically recorded by the cloud-based monitoring system platform is accurate and reliable, and the monitoring data can be easily analyzed and traced by all participating personnel.

[0017] This invention uses an automatic monitoring method to automatically alarm and correct ineffective compaction during the compaction process. That is, the system will alarm in real time for abnormal data (such as parameters that do not meet design requirements) and push rectification plans. At the same time, the entire construction process data of each compaction point will be automatically recorded and stored to form a complete electronic archive, so as to achieve full life-cycle quality traceability of construction data.

[0029] like Figure 5 As shown in the figure, this embodiment proposes an automatic monitoring system for the number of tamping blows and tamping energy during dynamic compaction construction, including: A data monitoring device is installed on the dynamic compaction machine and connected to the hammer. The data monitoring device includes a position monitoring module and a weight monitoring module, which are used to collect the position coordinates, elevation data and weight data of the compaction point. The cloud-based monitoring platform communicates with the data monitoring device to receive and process the location coordinates, elevation data, and weight data of the compaction points.

The elevation data from the data monitoring device is compared with the theoretical drop hammer elevation in real time to determine the validity of the drop hammer height. The validity of the hammer weight is determined by comparing the weight data with the preset weight. When the tamping point location, hammer drop height, and hammer weight are all valid, the number of valid tamping blows is counted; otherwise, an alarm is triggered and the reason for invalidity is recorded. When the number of effective tamping blows reaches the preset value, a tamping completion signal is generated.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] The system in this embodiment can be physically divided into a front-end data acquisition layer, a cloud-based data processing layer, and a user interaction layer. Data acquisition includes a data monitoring device 5, which is directly installed on the unhooker 4 of the dynamic compaction machine 1, enabling the unhooker 4 to move together with the hammer 6. In this embodiment, the data monitoring device 5 integrates a position monitoring module and a weight monitoring module. Specifically, the position monitoring module is a Global Navigation Satellite System 7 (GNSS) receiver with centimeter-level differential correction capability, capable of acquiring the three-dimensional coordinates and elevation data of the unhooker 4's location in real time with high precision. The weight monitoring module is specifically a tension sensor 3, installed on the wire rope 2 of the unhooker 4, used to sense the tension borne by the wire rope when the hammer 6 is lifted in real time. The data collected by the position monitoring module and the weight monitoring module can be transmitted to the cloud monitoring platform 8 via a wireless network (such as 4G / 5G) through the device's internal transmission module and IoT card. In this embodiment, the cloud monitoring platform 8 receives the data from the data monitoring device 5 and compares it with the construction parameters pre-input by engineers. The construction parameters specifically include the design coordinates of each compaction point, the required single-point compaction energy, and the theoretical weight of the tamping hammer 6. Therefore, before the dynamic compaction machine 1 is in place and the tamping hammer 6 is ready to begin operation, the system performs calibration. At this time, the position monitoring module continuously collects a set of position coordinates and elevation data, and determines the coordinates and elevation data of this point as the initial benchmark. Simultaneously, the tension sensor 3 is zeroed to eliminate the influence of initial tension, such as the weight of the equipment itself and the steel wire rope. When the compaction operation begins, each hammer lifting and lowering process is a complete cycle of data acquisition, judgment, and recording. Specifically, the system verifies whether the dynamic compaction machine 1 is accurately located at the predetermined compaction point by comparing the coordinates monitored in real-time by the position monitoring module with the preset position coordinates. If the deviation is within the allowable tolerance range (preferably a few centimeters), the compaction point position is deemed valid.

[0032] Based on the preset impact energy E and hammer weight M, the cloud monitoring platform can calculate the theoretically required hammer drop height h using the following formula:

[0033] In the formula: E This refers to the single-point impact energy of dynamic compaction. M For hammer weight; g It is the acceleration due to gravity; h This represents the drop height of the hammer.

[0034] Specifically, since the release device 4 and the tamping hammer 6 are rigidly connected, the height difference between their bottoms is a fixed value. Based on this, the system does not need to directly measure the height of the bottom of the tamping hammer 6, but indirectly calculates the actual hammer drop height by subtracting the initial reference elevation from the highest point elevation reached by the position monitoring module on the release device 4.

[0035] When the actual drop height reaches or exceeds the theoretical calculation value, the system determines that the drop height is valid. Simultaneously, the force monitored by the tension sensor 3 is converted into the actual weight of the tamping hammer 6 and compared with the preset theoretical weight. If they match, the weight of the tamping hammer 6 is determined to be valid. When both conditions are met, it indicates that the energy applied in this tamping operation meets the design requirements.

[0036] In this embodiment, the cloud monitoring platform 8 will only record a tamping impact as valid and record the valid count of the tamping point when all three conditions—position valid, height valid, and weight valid—are met simultaneously. If any one of the conditions is not met, such as excessive positional deviation, insufficient hammer lifting height, or abnormal weight detected, the system will immediately record the tamping impact as invalid and trigger an alarm mechanism. The alarm information will indicate which condition was not met and will also be pushed to the user interaction layer in real time via the wireless network.

[0037] The user interaction layer mainly includes a handheld terminal 9 or a computer. The handheld terminal 9 can be a handheld smartphone, tablet, or other device. Through the client terminal 10, operators can view the entire construction progress in real time anytime and anywhere.

[0038] See Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This embodiment proposes an automatic monitoring method for the number of impacts and impact energy during dynamic compaction construction: First, the construction site is cleaned and leveled, compaction points are marked, and the compaction positions are determined. Then, the dynamic compaction machine 1 is positioned. The compaction point positions can be arranged according to the shape of the foundation bottom surface, using equilateral triangles, isosceles triangles, or squares.

[0039] After the dynamic compaction machine 1 is in place, connect the unhooking device 4 to the hammer 6, tighten the unhooking device wire rope 2, and complete the preparations for dynamic compaction.

[0040] The data monitoring device 5 uses the receiver of the global navigation satellite system 7 to perform initial value calibration of the positioning coordinates and elevation of the unhooker 4 to obtain centimeter-level tamping point positioning coordinates and elevation data, and at the same time, it performs initial value zeroing calibration of the tension sensor 3.

[0041] The calibration coordinate data obtained by the data monitoring device 5 is compared with the pre-input coordinate information through the cloud monitoring system platform 8. When the error value is within the allowable range, the compaction point position is valid and meets the construction requirements, and the next step of dynamic compaction construction work for that compaction point can be carried out.

[0042] Simultaneously, the initial elevation of the unhooker 4 is determined by the correction elevation data obtained by the data monitoring device 5. The hammer drop height is calculated by the pre-set impact energy and hammer weight 6 in the cloud monitoring system platform 8. Then, the theoretical hammer drop elevation is automatically calculated by the cloud monitoring system platform 8 based on the hammer drop height and the initial elevation, and the hammer is lifted for impact.

[0043] The cloud monitoring system platform 8 compares the real-time elevation of the unhooker 4 with the calculated theoretical elevation. When the elevations match, the cloud monitoring system platform 8 automatically determines that the hammer drop height of this tamping is valid. At the same time, the force sensor 3 monitors the force on the unhooker 4. When the force on the unhooker 4 matches the theoretical weight of the hammer 6, the cloud monitoring system platform 8 automatically determines that the weight of the hammer 6 is valid.

[0044] When the cloud monitoring system platform 8 determines that the tamping point location, hammer drop height, and hammer weight are all valid, the cloud monitoring system platform 8 determines that the tamping is valid and counts one valid tamping count. Otherwise, it counts one invalid tamping count, issues an alarm for the invalidity, and records the reason for the invalid tamping until the tamping of the tamping point is completed.

[0045] During the dynamic compaction construction process, the cloud monitoring system platform 8 transmits real-time data of the construction process to the handheld terminal 9 or client 10 through the transmission module. All participating units in the construction process can view and monitor the data of the construction process online, and analyze the reasons for ineffective compaction automatically recorded by the cloud monitoring system platform 8 to rectify the construction process and ensure construction quality.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the scope of the invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
