Description

Technical Field

[0001] This application belongs to the technical field of geotechnical engineering construction equipment, and in particular relates to a high-pressure jet grouting construction grouting data monitoring system. Background Technology

[0002] In the process of high-pressure jet grouting, pressure and flow rate are crucial construction parameters. Traditional construction processes often rely on manual experience for control, following the principle of "low-pressure drilling and high-pressure lifting." However, precise control of pressure plays a decisive role in the quality of pile formation.

[0003] However, existing technologies have the following significant shortcomings: First, when the distance between the piling machine and the grouting station is large, considering only the pressure at the grouting station end cannot accurately reflect the actual grouting pressure, which will inevitably have a negative impact on the quality of pile formation. Second, in terms of flow monitoring, there is a lack of effective real-time statistical methods, making it difficult to accurately determine whether the cement usage over a period of time is reasonable, and supervisors cannot promptly detect whether construction workers are abusing cement on site. Third, existing control methods are mostly one-way transmissions, only transmitting on-site construction data to the backend, lacking the ability to adjust on-site equipment in real time, resulting in anomalies such as overpressure or insufficient flow often only being discovered after defects in pile formation quality have occurred. Utility Model Content

[0004] In view of this, this application aims to propose a high-pressure jet grouting construction grouting data monitoring system to solve problems such as unstable pile quality, material abuse and equipment wear and tear.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: This application provides a high-pressure jet grouting construction grouting data monitoring system, including a grouting data acquisition module, an integrated controller, a data transmission module, and a remote monitoring system connected together; The grouting data acquisition module is used to collect grouting pressure data and grouting flow rate data. The integrated controller is used to receive the grouting pressure data and the grouting flow rate data, and send the data to the remote monitoring system through the data transmission module; The remote monitoring system is used to compare the received data with preset standard data and to provide alarm prompts for abnormal data.

[0006] Furthermore, the grouting data acquisition module includes a grouting pressure acquisition module and a grouting flow rate acquisition module; The grouting pressure acquisition module is installed on the grout pipeline near the jet grouting machine to collect grouting pressure data at the end of the machine. The grouting flow acquisition module is installed on the pipeline between the grout tank and the booster pump to collect grouting flow data in the pipeline.

[0007] Furthermore, the grouting flow acquisition module uses an electromagnetic flow meter.

[0008] Furthermore, the integrated controller consists of a 12V regulated power supply and a data controller. The regulated power supply is electrically connected to the grouting pressure acquisition module, the grouting flow acquisition module, and the data controller to provide power to each module.

[0009] Furthermore, the data transmission module adopts a DTU wireless data transmission unit, which is electrically connected to the data controller via a serial port.

[0010] Furthermore, the remote monitoring system includes a data receiving unit, a data analysis module, and a display terminal; The data receiving unit is used to receive the data sent by the data transmission module and transmit it to the data analysis module. The data analysis module compares the received grouting pressure data and grouting flow rate data with the preset standard grouting pressure value and the marked grouting flow rate value. The display terminal is used to display the comparison results.

[0011] Furthermore, it also includes an audible and visual alarm unit, which is used to provide alarm prompts for abnormal results.

[0012] Compared with existing technologies, the high-pressure jet grouting construction grouting data monitoring system described in this application has the following advantages: (1) Real-time monitoring: Through the coordinated work of the grouting pressure acquisition module, grouting flow acquisition module, integrated controller, data transmission module and remote monitoring system, real-time monitoring of grouting pressure and flow is realized, providing construction personnel with timely and accurate information to facilitate timely adjustment of construction parameters.

[0013] (2) Ensure grouting pressure: By comparing the grouting pressure acquisition module installed on the pile driver side with the high pressure pump pressure gauge at the grouting station end, the pressure loss along the way can be obtained. When the distance between the pile driver and the grouting station is far, the grouting station can be notified to increase or decrease the pressure based on the real-time monitoring value of the grouting pressure.

[0014] (3) Ensure construction safety: It can detect and correct grouting pressure in a timely manner, effectively avoiding damage to the booster pump caused by excessive pressure and pile quality problems caused by insufficient grouting flow.

[0015] (4) Remote real-time feedback control: The two-way communication and feedback control function of the on-site monitoring and remote monitoring platform allows the back-end management personnel to monitor the changes in grouting pressure and flow rate in real time on the platform, and remotely adjust the construction parameters when the data is abnormal, so as to realize closed-loop control of the whole process.

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0019] Please see Figure 1 As shown, this embodiment provides a grouting data monitoring system for high-pressure jet grouting construction, including a grouting data acquisition module, an integrated controller, a data transmission module, and a remote monitoring system connected to each other; The grouting data acquisition module is used to collect grouting pressure data and grouting flow rate data. The integrated controller is used to receive grouting pressure data and grouting flow data, and sends the data to the remote monitoring system through the data transmission module; The remote monitoring system is used to compare the received data with preset standard data (it should be noted that, considering the on-site grouting construction situation, the specific value of the standard data can be flexibly adjusted according to the actual situation, and this embodiment does not make specific limitations) and to provide alarm prompts for abnormal data.

[0020] The high-pressure jet grouting construction grouting data monitoring system described in this embodiment achieves real-time monitoring of grouting pressure and flow rate through the coordinated operation of the grouting data acquisition module, integrated controller, data transmission module, and remote monitoring system. This provides construction personnel with timely and accurate information, facilitating timely adjustment of construction parameters. Simultaneously, back-end management personnel can monitor changes in grouting pressure and flow rate in real time on the platform and remotely adjust construction parameters when data anomalies occur, achieving closed-loop control throughout the entire process.

[0021] Specifically, in this implementation, the grouting pressure acquisition module uses a high-pressure resistant wireless grouting pressure acquisition device, installed on the grout pipeline near the jet grouting machine. As the cement grout flows through the pipeline, it monitors the grout pressure in real time and sends the monitored pressure value to the data controller. The grouting flow acquisition module uses an electromagnetic flow meter, installed between the grout tank and the booster pump pipeline. As the cement grout flows through the pipeline, it monitors the grout flow rate in real time and sends the monitored flow rate value to the data controller.

[0022] The integrated controller consists of two parts: a 12V regulated power supply and a data controller. (It should be noted that the integrated controller described in this embodiment is a product actually purchased by the department and is not considered an improvement to this embodiment; therefore, it will not be described in detail further.) The 12V regulated power supply powers the data controller, the grouting pressure acquisition module, and the grouting flow acquisition module. The data controller receives data measured by the grouting pressure module and the grouting flow acquisition module in real time and transmits it to the DTU wireless data transmission unit through its port.

[0023] Data transmission module and remote monitoring system: The data transmission module uses wireless transmission technology (4G or 5G) to quickly and stably transmit grouting flow rate and grouting pressure data to the remote monitoring system. The remote monitoring system includes a data receiving module, a data analysis module, and a display terminal. The data receiving module receives the data sent by the data transmission module and transmits it to the data analysis module. The data analysis module performs real-time analysis of the received data and compares it with pre-set grouting flow rate and standard grouting pressure construction standards.

[0024] When the data exceeds the standard range, the system immediately activates the alarm mechanism, issuing abnormal prompts to construction personnel through audible and visual alarms; at the same time, the display terminal displays the changes in grouting flow and pressure in real time in an intuitive chart format, allowing construction personnel to keep track of the construction status at any time.

[0025] The specific setup process of the system in this embodiment during practical application is as follows: (I) System Composition and Installation 1. Installation of grouting pressure acquisition module A high-pressure grouting pressure wireless acquisition device was selected and installed on the grout pipeline near the jet grouting machine to ensure that the actual grouting pressure at the end of the pile driver could be directly obtained.

[0026] 2. Installation of Grouting Flow Acquisition Module An electromagnetic flow meter is used and installed on the pipeline between the slurry tank and the booster pump to accurately monitor the flow rate of the cement slurry.

[0027] 3. Integrated controller deployment The integrated controller consists of a 12V regulated power supply and a data controller. Connect the 12V regulated power supply to the data controller to ensure a stable power supply to the data controller, grouting pressure acquisition module, and grouting flow acquisition module.

[0028] 4. Data transmission module and remote monitoring system setup The data transmission module uses 4G or 5G wireless transmission technology to achieve fast and stable data transmission. The remote monitoring system includes a data receiving module, a data analysis module, and a display terminal. Properly connecting and debugging each component ensures the system operates normally.

[0029] (II) Data Acquisition and Transmission Process 1. Pressure data acquisition and transmission When cement grout passes through a pipeline equipped with a wireless grouting pressure acquisition device, the device monitors the grout pressure in real time and sends the grouting pressure value to the data controller in real time.

[0030] 2. Traffic data collection and transmission The cement slurry flows through the electromagnetic flow meter, and the grouting flow acquisition module monitors the flow rate in real time and transmits the flow rate value to the data controller in real time.

[0031] 3. Centralized Data Processing and Transmission The data controller receives pressure and flow data in real time and transmits the data to the data wireless transmitter (DTU) via the port.

[0032] (III) Remote monitoring and feedback control 1. Data reception and analysis The data transmission module sends data to the data receiving device of the remote monitoring system, which then transmits the data to the data analysis module. The data analysis module performs real-time analysis on the received data and compares it with the pre-set grouting flow and pressure construction standards.

[0033] 2. Abnormal alarm handling If the data exceeds the standard range, the system will immediately activate the alarm mechanism and issue an abnormality warning to the construction personnel through audible and visual alarms.

[0034] 3. Visual display of construction status The display terminal shows the changes in grouting flow and pressure in real time in an intuitive chart format, making it convenient for construction personnel to keep track of the construction status at any time.

[0035] 4. Pressure regulation feedback When the distance between the piling rig and the grouting station is relatively far, the real-time pressure value monitored by the wireless grouting pressure acquisition device on the piling rig side is compared with the pressure gauge value of the high-pressure pump at the grouting station end to determine the pressure loss along the grouting path. Based on the loss result, the grouting station is notified to perform pressurization or depressurization operations to ensure the accuracy of the grouting pressure.
