Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and in particular to a device for measuring the pressure of deep foundation pit confined water dewatering. Background Technology

[0002] The deep foundation pit confined water dewatering pressure measuring device is a specialized piece of equipment used to measure the pressure changes of confined water in deep foundation pits. During the construction of deep foundation pit projects, the presence of confined water significantly impacts the stability of the pit. The device's basic principle is based on pressure sensor technology. By placing a pressure sensor at an appropriate location within the confined water layer, the pressure signal of the confined water is converted into an electrical signal for measurement and recording. Measuring the pressure of confined water dewatering is crucial in deep foundation pit projects. Accurately understanding the pressure changes of confined water is of great significance for ensuring the safety and stability of deep foundation pit projects.

[0003] However, existing technologies for measuring the pressure of confined aquifer dewatering in deep foundation pits present several pressing problems. Firstly, traditional measuring devices often require prolonged hand-held operation when measuring the same location over extended periods. This is not only time-consuming and labor-intensive but also prone to operator fatigue, impacting measurement accuracy and efficiency. Prolonged hand-held operation can also lead to shaking due to human error, further reducing the reliability of the measurement data. Secondly, existing measuring devices are often cumbersome to operate, requiring complex installation and debugging processes, increasing both time and labor costs. Therefore, improving and innovating deep foundation pit confined aquifer dewatering pressure measuring devices is a pressing issue that needs to be addressed. Utility Model Content

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1This utility model includes a measuring host. The front panel of the measuring host 2 is equipped with control buttons 3 and a data display screen 4. A measuring connector 5 is located on the right side panel of the measuring host 2. Connector A6 is attached to connector A6, which is connected to one end of a tensile testing wire 8. The other end of the tensile testing wire 8 is connected to one end of connector B9, and a pressure sensor probe 10 is located at the other end of connector B9. The measuring host 2 is mounted on an adjustable auxiliary bracket 1. The pressure sensor probe 10 measures the pressure of the confined water in the deep foundation pit. The pressure sensor probe 10 senses the pressure of the confined water in the deep foundation pit and converts the pressure signal into an electrical signal, which is transmitted to the measuring host 2 via the tensile testing wire 8. The measuring host 2 processes and analyzes the received electrical signal and displays the pressure data on the data display screen 4.

[0026] Furthermore, the measuring host 2 has a built-in PLC programmable logic controller. The pressure data collected by the measuring host is calculated, analyzed, and processed, and then displayed on the data display screen 4.

[0027] Reference Figure 3-4 The adjustable auxiliary support 1 described in this embodiment includes an internally threaded support cylinder 12, a screw fixing plate 13, a screw main support 14, and a metal fixing head 15. The screw fixing plate 13 is fixed to the bottom of the measuring host 2 by multiple screws. A metal fixing head 15 is welded to the center of the bottom end of the screw fixing plate 13, and a screw main support 14 is welded to the bottom end of the metal fixing head 15. The internally threaded support cylinder 12 is fitted onto the external thread of the screw main support 14. The internally threaded support cylinder 12 can rotate clockwise and counterclockwise, and its threads can act on the outside of the screw main support 14 to move upward and downward. When the measuring host needs to be operated by hand, the auxiliary support can be used as a handle. Simply hold the internally threaded support cylinder on the auxiliary support in its retracted state, providing the operator with a comfortable grip and facilitating various measurement operations.

[0028] Reference Figure 3-4In a further optional embodiment, the adjustable auxiliary support 1 further includes a tapered tip 11 and an internal thread locking sleeve 16. The internal thread of the internal thread locking sleeve 16 is sleeved on the external thread of the screw main support 14 above the internal thread support cylinder 12. The internal thread locking sleeve 16 can rotate clockwise and counterclockwise and move downward and upward outside the screw main support 14 through the action of the thread. The tapered tip 11 is welded to the bottom of the internal thread support cylinder 12, and the tip of the tapered tip 11 faces downward. This embodiment can be directly used as a fixed support. The bottom end of the internally threaded support cylinder is welded with a conical tip, with the tip pointing downwards. The conical tip can be inserted into the ground next to the foundation pit, at which point the auxiliary support acts as a fixed support. This fixing method is stable and reliable, ensuring that the measuring host will not shake or shift during the measurement process, thus guaranteeing the stability and reliability of the measurement data. At the same time, the internally threaded support cylinder of this adjustable auxiliary support is connected to the main screw support through a thread, allowing the internally threaded support cylinder to rotate clockwise and counterclockwise. Through the action of the thread on the outside of the main screw support, it can move upwards and downwards, thereby flexibly changing the overall length. This feature allows the auxiliary support to adapt to different terrains and measurement needs during use. Whether next to an uneven foundation pit or in situations where a specific height is required for measurement, the appropriate measurement height can be achieved by adjusting the position of the internally threaded support cylinder, improving the accuracy and convenience of the measurement.

[0029] Reference Figure 1 Furthermore, the right panel of the measuring host 2 is equipped with multiple data export holes 7, and a wireless transmission module is located on the panel below the data export holes 7. All data export holes 7 and the wireless transmission module are electrically connected to the PLC programmable logic controller built into the measuring host 2. The wireless transmission module can transmit the measured data to an external terminal via a wireless network, facilitating remote monitoring and data storage for users.

[0030] Furthermore, the wireless transmission module is a Bluetooth module or a USB wireless module, which can transmit the data measured by the measuring host 2 to an external terminal via a wireless network.

[0031] Furthermore, a charging port is provided on the left side panel of the measuring host 2, and the charging port is electrically connected to the PLC programmable logic controller built into the measuring host 2. Charging can be performed through the charging port.

[0032] Furthermore, the control buttons 3 are located below the data display screen 4 and consist of multiple physical push-button buttons.

[0033] Furthermore, the top and bottom of the measuring host 2, perpendicular to both sides of the data display screen 4, are both blunted into an arc shape.

[0034] Furthermore, the measuring connector 5 is located on the lower panel of the wireless transmission module, and the measuring connector 5 is electrically connected to the PLC programmable logic controller built into the measuring host 2.

[0035] Furthermore, a transparent protective film is affixed to the outer wall of the data display screen 4 to protect the screen.

[0036] like Figure 1 and Figure 2 As shown, when using this deep foundation pit confined water dewatering pressure measuring device, first check whether all components of the measuring device are intact, including the measuring host 2, pressure sensor probe 10, tensile measuring wire 8, etc., and ensure that the measuring host 2 has sufficient power. It can be charged through the charging port. Connect the connector A6 to the measuring connector 5 on the lower side of the center of the right end of the measuring host 2, ensuring that the tensile measuring wire 8 is stably connected. Then install the pressure sensor probe 10 onto the connector B9 at the other end of the tensile measuring wire 8. Then press the control button 3 on the measuring host 2 to turn on the measuring host 2, grasp the tensile measuring wire 8 and drop the pressure sensor probe 10 into the foundation pit water body to be measured, and then slowly release the tensile measuring wire 8 so that the pressure sensor... The probe 10 can slowly descend into the water and reach the required measurement depth. At this time, the measuring host 2 begins to receive the signal transmitted by the pressure sensor probe 10, processes and displays it. The user needs to observe the data display screen 4 on the measuring host 2 to read the current pressure data of the confined water in the deep foundation pit. At the same time, the user can receive the measurement data sent by the wireless transmission module through an external terminal for remote monitoring and analysis. If it is necessary to export the measurement data for further analysis or storage, the user can connect to an external device to export the data through the multiple data export holes 7 inside the upper side of the center on the right end of the measuring host 2. After the measurement is completed, press the control button 3 on the measuring host 2 to turn off the measuring device, remove the pressure sensor probe 10 from the measurement position, and properly store the measuring device.

[0037] like Figure 1 , Figure 3 and Figure 4As shown, an adjustable auxiliary support 1 is provided at the bottom of the measuring host 2. The adjustable auxiliary support 1 includes an internally threaded support cylinder 12, a screw fixing plate 13, a screw main support 14, and a metal fixing head 15. The screw fixing plate 13 is fixed to the bottom of the measuring host 2 by multiple screws. A metal fixing head 15 is welded to the center of the bottom end of the screw fixing plate 13. The screw main support 14 is welded to the bottom end of the metal fixing head 15. The internally threaded support cylinder 12 is threaded onto the outside of the screw main support 14. The screw fixing plate 13 is fixed to the bottom of the measuring host 2 by multiple screws, providing a solid connection foundation for the entire auxiliary support. The welding connection of the metal fixing head 15 further enhances the connection strength between the various components of the auxiliary support, ensuring that no problems occur during use. In case of loosening or detachment, the adjustable auxiliary support 1 also includes a tapered tip 11 and an internal thread locking sleeve 16. The internal thread locking sleeve 16 is threaded onto the outside of the screw main support 14 and is located on the upper side of the internal thread support cylinder 12. The tapered tip 11 is welded to the bottom end of the internal thread support cylinder 12, with the tip of the tapered tip 11 pointing downwards. The design of the tapered tip 11 allows the auxiliary support to be easily inserted into the ground, providing stable fixed support for the measuring host 2. At the same time, when it is necessary to operate the measuring host 2 by hand, the operator can hold the internal thread support cylinder 12 on the auxiliary support in the stored state. At this time, the auxiliary support acts as a handle for convenient operation. This diversified fixing method meets the needs of different measurement scenarios.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, the internally threaded support cylinder 12 can rotate clockwise and counterclockwise, allowing it to move upwards and downwards on the outside of the screw main support 14 through the action of the thread. Similarly, the internally threaded locking sleeve 16 can rotate clockwise and counterclockwise, allowing it to move downwards and upwards on the outside of the screw main support 14 through the action of the thread. The threaded engagement between the internally threaded support cylinder 12 and the screw main support 14 allows the height of the auxiliary support to be flexibly adjusted according to actual measurement needs. Whether measuring next to pits of different depths or adapting to the height and operating habits of different operators, the optimal measurement position and angle can be achieved by adjusting the height of the auxiliary support, improving the accuracy and convenience of the measurement. The internally threaded locking sleeve 16 further enhances the stability of the auxiliary support. After adjusting the height of the internally threaded support cylinder 12, the locking action of the internally threaded locking sleeve 16 can effectively prevent the internally threaded support cylinder 12 from moving due to external forces or vibrations during the measurement process, ensuring the stability and reliability of the measurement data.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
