Description

Technical Field

[0001] This utility model belongs to the field of monitoring system technology, specifically a real-time monitoring system for grouting quality. Background Technology

[0002] In numerous fields such as water conservancy and hydropower, transportation infrastructure, mining, and construction engineering, grouting technology, as a key foundation treatment and reinforcement method, is widely used in engineering scenarios such as filling cracks in soil and rock, improving the bearing capacity of the foundation, and blocking groundwater seepage. Its construction quality directly determines the stability, safety, and durability of the engineering structure. For example, in the foundation treatment of water conservancy dams, curtain grouting forms a seepage-proof curtain, which can effectively reduce the leakage of the dam foundation and ensure the long-term safe operation of the dam. In highway subgrade reinforcement projects, pressure grouting technology can eliminate hidden dangers such as subgrade voids and looseness, avoiding subsequent pavement settlement and cracking.

[0003] However, the quality monitoring of grouting projects still faces many technical bottlenecks. Traditional monitoring methods and existing monitoring technologies are insufficient to meet the project's requirements for precise control of grouting quality, mainly in the following aspects: First, traditional grouting quality monitoring relies heavily on a "post-inspection" model, lacking real-time capabilities and process control. Currently, commonly used methods in the industry, such as core drilling and water pressure testing, must be conducted after grouting is completed. This only allows for sampling inspection of the grouting effect in localized areas and cannot reflect key parameters in real time, such as the grout diffusion range, the state of stone formation, and the dynamic matching relationship between grouting pressure and flow rate. This "post-inspection" approach not only suffers from detection delays, but also often results in wasted construction costs by the time quality problems are discovered. Furthermore, it is difficult to accurately pinpoint the specific construction stage and cause of the problem, leading to significant rework difficulties and high repair costs. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figure 1 This utility model provides a real-time monitoring system for grouting quality. By collecting and analyzing key parameters of the grouting process in real time, it enables real-time control and early warning of abnormalities in grouting quality, solves the problem of lag in traditional monitoring, and improves the quality and efficiency of engineering construction.

[0019] The real-time grouting quality monitoring system provided in this application includes a parameter acquisition unit 10, a data transmission unit 20, a data processing unit 30, a display and early warning unit 40, and a power supply unit 50. The acquisition end of the parameter acquisition unit 10 is used to be deployed corresponding to the grouting construction equipment and grouting area to ensure accurate acquisition of key parameters during the construction process. The output end of the parameter acquisition unit 10 is electrically connected to the input end of the data transmission unit 20 to realize real-time transmission of the acquired data. The output end of the data transmission unit 20 is communicatively connected to the input end of the data processing unit 30, which can be wired or wirelessly connected to ensure the stability of data transmission. The output end of the data processing unit 30 is electrically connected to the input end of the display and early warning unit 40 to facilitate real-time viewing of monitoring results by staff. The power supply unit 50 is electrically connected to the parameter acquisition unit 10, the data transmission unit 20, the data processing unit 30, and the display and early warning unit 40 respectively, providing stable working power to each unit. It can be powered by a lithium battery pack or external mains power and is equipped with a backup power module to prevent monitoring interruption due to power failure.

[0020] In actual operation, the parameter acquisition unit 10 collects pressure parameters, flow parameters, and grout diffusion parameters in real time during the grouting process. The pressure parameter reflects the stability of the grouting equipment's output pressure, the flow parameter reflects the grout injection rate, and the grout diffusion parameter determines the grout's filling range in the soil and rock mass. The data transmission unit 20 transmits the collected parameter data to the data processing unit 30 in real time. The data processing unit 30 has a built-in preset grouting quality standard parameter range and compares and analyzes the received parameter data to determine whether the current grouting quality meets the standard. For example, if the pressure parameter exceeds the preset safety range or the flow parameter shows abnormal fluctuations, it is determined that there is a risk to the grouting quality. The display and early warning unit 40 displays the various parameter data and the quality judgment results output by the data processing unit 30 in real time on the display screen. If it is determined that the grouting quality does not meet the preset standard, the display and early warning unit 40 will immediately issue an early warning signal through an audible and visual alarm to remind the staff to adjust the construction parameters in time to avoid the quality problem from escalating.

[0021] In an optional embodiment of this example, the parameter acquisition unit 10 includes a pressure sensor 11, a flow sensor 12, and a diffusion monitoring component 13. The acquisition end of the pressure sensor 11 is connected to the grout output pipeline of the grouting construction equipment to collect grout delivery pressure data. The flow sensor 12 is connected in series in the grout output pipeline to collect grout flow data in real time. The diffusion monitoring component 13 includes multiple humidity sensors embedded in the soil and rock mass of the grouting area. These multiple humidity sensors are arranged at intervals along a preset path for grout diffusion. By detecting changes in the humidity of the soil and rock mass, the diffusion range of the grout is determined, thereby obtaining grout diffusion parameters. By using a combination of multiple types of sensors, key parameters of the grouting process can be comprehensively collected, providing sufficient data support for quality judgment.

[0022] In an optional embodiment of this example, the data transmission unit 20 includes a wired transmission module 21 and a wireless transmission module 22. The wired transmission module 21 uses an RS485 communication bus and is connected to the parameter acquisition unit 10 and the data processing unit 30 respectively. It is suitable for scenarios where the wiring conditions in the monitoring area allow, and has the advantages of stable transmission and strong anti-interference ability. The wireless transmission module 22 uses LoRa wireless communication technology and is set in parallel with the wired transmission module 21. When the wired transmission fails, it automatically switches to the wireless transmission mode to ensure the continuity of data transmission and avoid monitoring failure due to transmission interruption.

[0023] In an optional embodiment of this example, the data processing unit 30 includes a data storage module 31, a data analysis module 32, and a standard parameter configuration module 33. The data storage module 31 stores historical parameter data and quality judgment results transmitted by the data transmission unit 20, facilitating subsequent project review and quality traceability. The data analysis module 32 compares and analyzes the real-time collected parameter data with the preset standard parameter range in the standard parameter configuration module 33, calculates the parameter deviation value, and determines the grouting quality level based on the magnitude of the deviation value, classifying it into three levels: qualified, warning, and unqualified. The standard parameter configuration module 33 allows staff to manually modify the preset standard parameter range according to different project types (such as grouting of water conservancy hub dam foundations and grouting of highway subgrades), improving the applicability of the system.

[0024] In an optional embodiment of this example, the display and warning unit 40 includes a touch screen 41, an audible and visual alarm 42, and a warning signal output interface 43. The touch screen 41 is used to display parameter data, quality judgment results, and a historical data query interface, allowing staff to retrieve monitoring data for different time periods via touch operation. The audible and visual alarm 42 includes a red alarm light and a buzzer. When a warning signal is issued, the red alarm light flashes, and the buzzer emits an intermittent alarm sound, ensuring that staff can quickly detect the warning in complex construction environments. The warning signal output interface 43 can be connected to the control system of the grouting construction equipment. While issuing the warning signal, it outputs a control signal to the construction equipment control system to achieve automatic adjustment of construction parameters. For example, when the pressure is too high, it automatically reduces the output pressure of the grouting equipment, improving the system's automated control capabilities.

[0025] In an optional embodiment of this example, the power supply unit 50 includes a main power supply module 51, a backup power supply module 52, and a power monitoring module 53. The main power supply module 51 is powered by 220V AC mains power, and the voltage is converted into the DC voltage required by each unit through a power adapter. The backup power supply module 52 is a lithium battery pack connected in parallel with the main power supply module 51. When the main power supply module 51 is powered off, the backup power supply module 52 automatically switches to power supply to ensure that the system continues to work for at least 4 hours, meeting the monitoring requirements under temporary power outage conditions. The power monitoring module 53 is connected to both the main power supply module 51 and the backup power supply module 52, and monitors the power supply voltage and current status in real time. It transmits the power supply status data to the display and early warning unit 40 for display. When the main power supply is abnormal or the backup power supply module 52 is low on power, it issues an early warning to remind staff to handle the situation in a timely manner.

[0026] The real-time grouting quality monitoring system collects key parameters of the grouting process in real time through a parameter acquisition unit, transmits them to a data processing unit for analysis and judgment through a data transmission unit, and finally presents the results and provides anomaly warnings through a display and early warning unit. This breaks away from the traditional "post-event detection" model and enables real-time monitoring and process control of grouting quality. Furthermore, through multi-sensor acquisition, dual-transmission mode backup, and backup power supply design, the system's stability and applicability are improved. It effectively reduces engineering rework costs, ensures grouting construction quality, and is suitable for grouting engineering monitoring scenarios in multiple fields such as water conservancy and hydropower, and transportation infrastructure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
