Description

Technical Field

[0001] This utility model relates to the field of measurement technology, and in particular to a device for measuring the index of pile foundation mud. Background Technology

[0002] During pile foundation construction, the quality and condition of the drilling mud play a crucial role in the construction quality and stability of the pile foundation. The flow rate, density, and level of the drilling mud are key parameters for evaluating its performance. Accurately measuring these parameters is essential for ensuring the smooth progress of pile foundation construction and guaranteeing the quality of the pile foundation.

[0003] Currently, traditional methods for determining mud parameters in pile foundations often have several limitations. For example, in flow rate measurement, there is usually a lack of specialized, precise real-time monitoring devices, making it difficult to continuously and accurately control the flow rate during mud output. This results in construction personnel being unable to promptly understand the mud output situation, thus affecting the construction progress. In level detection, traditional methods may not be intuitive or precise enough, making it difficult to obtain the mud level height within the pile foundation in real time. This may prevent construction personnel from promptly grasping changes in the mud level, leading to situations where the mud level is too high or too low during construction, affecting the quality and safety of pile foundation construction. Furthermore, existing mud parameter measuring devices often lack effective integration and collaborative working mechanisms between their various measuring components. Measurement data is scattered, making it inconvenient for construction personnel to centrally view and analyze it, and also preventing timely adjustment and control of relevant mud parameters based on the measurement results, reducing construction efficiency and quality.

[0022] Please see Figures 1 to 2 This application provides a device for measuring the mud index of a pile foundation 7, including a mud output pipe 1, a flow measuring unit 2, a density measuring unit 3, a liquid level detection unit 4, and a display and control unit 5. One end of the mud output pipe 1 is connected to a mud pump, and the other end extends into the pile foundation 7. The flow measuring unit 2 is mounted on the mud output pipe 1. The density measuring unit 3 is fixed to the ground by a bracket 6, and its measuring head extends into the mud within the pile foundation 7. The liquid level detection unit 4 is fixed to the bracket 6, and its position is vertically downwards towards the mud surface of the pile foundation 7. The display and control unit 5 is electrically connected to the flow measuring unit 2, the density measuring unit 3, and the liquid level detection unit 4 via wires 8.

[0023] This invention uses a mud pump to pump mud out of the pile foundation 7 through a mud output pipe 1. A flow measurement unit 2 is installed on the mud output pipe 1 to monitor the flow rate of the mud. The density and level of the mud are measured by a density measurement unit 3 and a level detection unit 4 inside the pile foundation 7. The flow measurement unit 2, density measurement unit 3, and level detection unit 4 are electrically connected to a display control unit 5 to display various parameters of the mud. The display control unit 5 can also control the operation of the flow measurement unit 2, density measurement unit 3, and level detection unit 4.

[0024] In one embodiment, the flow measurement unit 2 includes an electromagnetic flow meter. The electromagnetic flow meter has advantages such as high measurement accuracy, good stability, and fast response speed. Using it as the flow measurement unit 2 allows for real-time and accurate acquisition of the flow rate data of the mud in the output pipe, unaffected by changes in the physical properties of the mud such as temperature, pressure, and viscosity, resulting in accurate and reliable measurement results. This helps construction personnel to understand the mud output status in a timely manner, rationally adjust the operating parameters of the mud pump, avoid construction problems caused by abnormal flow, and improve construction efficiency and quality.

[0025] In one embodiment, the density measuring unit 3 includes a tuning fork density meter. The tuning fork density meter measures the mud density by measuring the change in the vibration frequency of a tuning fork. It has the advantages of high measurement accuracy and rapid response. Construction personnel can use accurate density data to ensure that the mud performance meets the requirements of pile foundation 7 construction and prevent the bearing capacity and stability of pile foundation 7 from being affected by unsuitable mud density.

[0026] In one embodiment, the liquid level detection unit 4 includes a radar liquid level sensor. The radar liquid level sensor uses the principle of electromagnetic wave reflection to measure the liquid level, and has advantages such as high measurement accuracy, insensitivity to medium properties, and strong anti-interference ability.

[0027] Optionally, both the density measuring unit 3 and the liquid level detection unit 4 are hinged to the bracket 6 via connecting rods, allowing the density measuring unit 3 and the liquid level detection unit 4 to be rotated and adjusted in the horizontal plane. This enables the density measuring unit 3 and the liquid level detection unit 4 to be conveniently adjusted in position by rotation, greatly improving the flexibility of the density measuring unit 3 and the liquid level detection unit 4 during monitoring.

[0028] In one embodiment, the display control unit 5 includes a display module 51, a control module 52, and a central processing unit. The central processing unit receives detection information from the flow measurement unit 2, the density measurement unit 3, and the liquid level detection unit 4 in real time, as well as instruction information input by the control module 52, and controls the display module 51 to work according to the detection information and instruction information.

[0029] Specifically, the display module 51 can intuitively and clearly display the detection information of various components such as the flow measurement unit 2, density measurement unit 3, and liquid level detection unit 4, allowing construction personnel to view various parameters of the mud in real time without having to check the data of each measuring component separately, thus improving operational convenience and work efficiency. Furthermore, construction personnel can input command information through the control module 52 to control the operation of each measuring component, such as starting or stopping measurement, adjusting measurement parameters, etc., achieving flexible control of the measurement process. The central processing unit, as the core of the display control unit 5, can receive detection information and command information in real time and perform rapid processing and analysis.

[0030] The display module 51 can be a display screen, and the control module 52 can be a control button.

[0031] In one embodiment, a viscosity measuring unit is also included. The viscosity measuring unit is mounted on a support 6, and its measuring end is located in the mud within the pile foundation 7. The viscosity measuring unit is electrically connected to a display and control unit 5 via a wire 8. Viscosity is one of the important indicators of mud performance, directly affecting the mud circulation and wall protection effects. Adding a viscosity measuring unit to the device and placing its measuring end in the mud within the pile foundation 7 allows for real-time and accurate measurement of the mud viscosity. By electrically connecting the viscosity measuring unit to the display and control unit 5, construction personnel can visually view the mud viscosity data on the display and control unit 5 and promptly understand changes in mud viscosity. Specifically, the viscosity measuring unit can be a rotational viscometer.

[0032] In one embodiment, an alarm light 9 is also included. The alarm light 9 is disposed on the top of the bracket and is electrically connected to the display control unit 5 via a wire. When the mud density, viscosity, liquid level, and other indicators received by the display control unit 5 are normal, the display control unit 5 controls the alarm light 9 to illuminate green. When the mud density, viscosity, liquid level, and other indicators received by the display control unit 5 exceed the normal threshold, the display control unit 5 controls the alarm light 9 to illuminate red. When the mud density, viscosity, liquid level, and other indicators received by the control unit 5 fluctuate within a certain range, the display control unit 5 controls the alarm light 9 to illuminate yellow.

[0033] This invention monitors the flow rate, liquid level, viscosity, and density of the mud in the foundation pile through a flow measurement unit, a liquid level detection unit, a viscosity measurement unit, and a density measurement unit, respectively. The monitoring data is transmitted (via wired or wireless transmission) to the display and control unit. After processing by the central processor, the data is displayed on the display module as a curve of the data changing over time, thereby realizing functions such as viscosity monitoring and early warning, density monitoring and early warning, liquid level change monitoring and early warning, collapse flow calculation and volume accumulation, collapse early warning SMS emergency notification, trend prediction and evaluation, dynamic curve numerical dual display and abnormal recording.

[0034] Specifically, the display and control unit is electrically connected to each measuring unit, receiving and processing detection information from the flow rate measuring unit, density measuring unit, and level detection unit in real time. The central processing unit (CPU), as the core processing unit, integrates, analyzes, and processes the data. After processing by the CPU, each data point is displayed as a curve showing its change over time on the display module. This dynamic curve display method allows operators to intuitively understand the changing trends of various mud parameters, facilitating timely detection of anomalies.

[0035] When the mud viscosity exceeds the preset range, the central processing unit will trigger a viscosity monitoring warning to remind operators to pay attention to changes in mud properties. Similarly, when the mud density exceeds the normal range, a density monitoring warning will also be triggered. The principle of flow rate monitoring warning is similar.

[0036] The liquid level detection unit monitors the mud level in real time. When the liquid level drops beyond the preset collapse threshold, it determines that a collapse is imminent within the pile. The central processing unit triggers a liquid level change monitoring and early warning system and may remotely notify relevant personnel via SMS to allow for timely measures to prevent the collapse. This enables emergency collapse warning SMS notifications. When a collapse occurs within the pile, the central processing unit automatically records the cumulative mud flow rate at the time of the collapse to calculate the cumulative volume of the collapsed flow.

[0037] In addition, the central processing unit automatically generates reports based on existing data curves, including monitoring data and analysis results of various indicators such as mud flow rate, liquid level, viscosity, and density, providing strong support for construction management.

[0038] The central processing unit can also evaluate the changes of various values ​​over time, predict the trend of mud performance changes, and provide a basis for construction adjustments to conduct trend prediction and evaluation.

[0039] The central processing unit (CPU) can record abnormalities in various mud parameters, including the time and value of the abnormality, providing data support for subsequent accident analysis and handling. It simultaneously displays dynamic curves and current values ​​on the display module, allowing operators to more intuitively understand the real-time status and trends of mud performance. This enables dual-display abnormal recording of dynamic curve values.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
