Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure sensor technology, specifically to an installation structure and a pressure sensor used for construction monitoring. Background Technology
[0002] During the construction of the foundation pit, in order to monitor the interaction force between the support structure and the surrounding soil in real time, and to ensure construction safety and the stability of the surrounding environment, a vibrating wire earth pressure gauge (also known as an earth pressure cell) is usually installed on the back side of the support structure to obtain the magnitude of the actual earth pressure and its distribution along the depth.
[0003] Currently, most earth pressure cells are rigidly fixed to the support structure (such as diaphragm walls, pile banks, etc.) via screws or connecting lugs located on the side furthest from the sensing end to ensure the stability of the sensor during construction. However, in actual engineering projects, due to soil deformation, displacement of the support structure, or inadequate backfill compaction, a "vacuum" phenomenon (i.e., partial or complete separation between the two) can easily occur between the support structure and the surrounding soil, forming gaps. Once this void occurs, the sensing surface of the earth pressure cell will not be able to effectively contact the soil, causing it to fail to accurately reflect the actual earth pressure, or even output an abnormally low pressure signal close to zero, seriously affecting the reliability of the monitoring data.
[0004] In existing technologies, determining whether a void has occurred mainly relies on manual periodic checks of pressure sensor data output. Even if the monitoring system can identify "pressure anomalies," it can only indicate that the value deviates from the normal range, failing to definitively indicate the specific condition of "void," still requiring on-site inspection by construction personnel. Furthermore, due to factors such as obstruction by the support structure, the small size of the void, or limited observation angles, manual judgment is often delayed, subjective, and uncertain, making rapid and accurate fault identification difficult.
[0005] In addition, although some earth pressure devices have been designed with adjustable functions in their installation structures, which can adjust the relative position between the sensor and the support structure after voiding occurs to make the sensing surface re-fit the soil, this adjustment operation usually requires clear confirmation of voiding. Without reliable voiding criteria, blind adjustment may not only interfere with normal monitoring, but may also introduce additional errors, which is obviously inconvenient in operation. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides an installation structure and a pressure sensor for construction monitoring. When the support structure becomes detached from the soil, a color-coded warning is issued, allowing the detachment to be observed directly with the naked eye.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a mounting structure located outside the sensor housing, the mounting structure comprising:
[0008] The screw secures the sensor housing to the external support structure.
[0009] An annular contact element that can conform to the soil;
[0010] The second elastic element can drive the annular contact element to always be in contact with the soil after the sensor housing is separated from the soil.
[0011] The indicator element changes color as it is driven by the second elastic element to adhere to the soil.
[0012] Furthermore, it also includes a support component that can support the prompt and change the orientation of the prompt.
[0013] Furthermore, it also includes an elastic component that can support the second elastic element, and the elastic component can also drive the annular contact element, the second elastic element, and the indicator element to reset after the sensor housing comes into contact with the soil.
[0014] Furthermore, it also includes at least two slide rails that can restrict the direction of movement of the elastic component.
[0015] Furthermore, the elastic component includes a first annular plate and a first elastic member. The inner wall of the first annular plate is slidably connected to the outer wall of the sensor housing. The two sides of the first annular plate are respectively fixedly connected to one end of the prompting member and one end of the first elastic member. The end of the first elastic member away from the first annular plate is connected to the support component.
[0016] Furthermore, the surface of the prompting element near the first annular plate is provided with several color indicator labels of different colors, and the end of the prompting element away from the first annular plate is fixedly connected to the side of the annular contact element away from the soil.
[0017] Furthermore, the support assembly includes a second annular plate and an annular column. The inner wall of the second annular plate is fixedly connected to the outer wall of the sensor housing. The two sides of the second annular plate are fixedly connected to the first elastic element and the second elastic element, respectively. The end of the second elastic element away from the second annular plate is fixedly connected to the side of the annular contact element away from the soil. The annular column is a hollow column. The side of the second annular plate close to the first elastic element is fixedly connected to one end of the annular column. The other end of the annular column is located at the corner of the indicator element.
[0018] Furthermore, the inner wall of the annular contact is provided with at least one second sliding groove, the inner wall of the first annular plate is provided with at least one first sliding groove, the outer wall of the sensor housing is fixedly connected to the slide rail, and the second sliding groove and the first sliding groove are slidably connected to the two slide rails respectively.
[0019] This utility model also provides the following technical solution: a pressure sensor for construction monitoring, including a sensor housing, a cavity formed inside the sensor housing, all the components required for the pressure sensor are located inside the cavity, and the pressure sensor has a detection end facing the soil.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] This type of installation structure and pressure sensor used for construction monitoring allow construction personnel to directly observe the void phenomenon and its degree with the naked eye through the color change of the indicator, without relying on monitoring data or professional tools. This solves the problems of lag and subjectivity in existing technologies that rely on manual periodic data checks, and achieves real-time and intuitive identification of voids.
[0022] This type of installation structure and pressure sensor used for construction monitoring allows the elastic component to automatically drive the annular contact, indicator, and second elastic component to reset after the detachment is repaired, eliminating the need for manual adjustment, reducing human error, lowering maintenance costs, and simplifying operation.
[0023] This type of installation structure and the pressure sensor used for construction monitoring indicate that the color change of the indicator directly corresponds to the specific working condition of "voiding out," rather than a vague numerical abnormality signal. This solves the problem of not being able to clearly identify the fault type in existing technologies, enabling construction personnel to quickly locate the voiding fault and avoid additional errors caused by blind adjustments.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0039] Please see Figures 1-6 A mounting structure located outside the sensor housing 100, the mounting structure comprising:
[0040] A screw, which secures the sensor housing 100 to the external support structure;
[0041] Annular contact element 200, which can conform to the soil;
[0042] The second elastic element 700 can drive the annular contact element 200 to always be in contact with the soil after the sensor housing 100 is separated from the soil.
[0043] The indicator 300 is capable of changing color during the process of the second elastic element 700 driving the annular contact 200 to adhere to the soil.
[0044] It also includes a support component 600, which can support the prompting component 300 and can also change the direction of the prompting component 300;
[0045] Specifically, by setting a screw on the outside of the sensor housing 100 and using a nut, the sensor housing 100 can be fastened to the support structure, thereby ensuring that the end of the sensor housing 100 away from the screw (i.e. the detection end) can be attached to the soil surface, thereby monitoring the soil pressure (soil refers to the soil on the surface around the foundation pit).
[0046] In addition, by adding an annular contact 200, a second elastic element 700 and a prompting element 300 to the outside of the sensor housing 100, when a gap occurs between the soil and the support structure, the second elastic element 700 can push the annular contact 200 to always adhere to the soil surface, thereby driving the prompting element 300 to change color, so that construction personnel can directly observe the gap phenomenon with the naked eye.
[0047] Furthermore, in order to ensure that the annular contact 200 can both enclose the sensor housing 100 and be displaced under the drive of the second elastic member 700, the shape of the annular contact 200 can be as follows: Figures 1-5 As shown, it is a hollow cylinder, and the side of the cylinder away from the detection end of the sensor housing 100 is open, so that the second elastic element 700 can push the annular contact 200 to move through this opening.
[0048] Furthermore, in order for the second elastic element 700 to drive the annular contact 200 to move, the second elastic element 700 can be a spring. Thus, when a gap occurs between the sensor housing 100 and the soil, the second elastic element 700 can push the annular contact 200 to continue to adhere to the soil surface. Moreover, after the gap occurs and is repaired by the construction personnel (e.g., by pushing the screw and sensor housing 100 back to the soil surface), the second elastic element 700 can retract into the outside of the sensor housing 100 in conjunction with the annular contact 200 without manual adjustment.
[0049] Furthermore, in addition to the screw, annular contact 200, second elastic element 700, and indicator 300, the installation structure also includes an elastic component 500. The elastic component 500 can support the second elastic element 700, and the elastic component 500 can also drive the annular contact 200, the second elastic element 700, and the indicator 300 to reset after the sensor housing 100 comes into contact with the soil.
[0050] To achieve the function of the aforementioned elastic component 500, as a preferred embodiment of this utility model, please refer to... Figure 4 and Figure 5 The elastic component 500 includes a first annular plate 510 and a first elastic member 520. The inner sidewall of the first annular plate 510 is slidably connected to the outer wall of the sensor housing 100. The two sides of the first annular plate 510 are respectively fixedly connected to one end of the prompting member 300 and one end of the first elastic member 520. The end of the first elastic member 520 away from the first annular plate 510 is connected to the support component 600.
[0051] Specifically, by setting a first elastic element 520 (which can be a spring), this spring is in a compressed state during normal detection, and the elastic force of the first elastic element 520 is less than that of the second elastic element 700. In this way, when the sensor housing 100 is separated from the ground, the second elastic element 700 can push the annular contact 200 to move, and the first elastic element 520 is stretched at this time. After the construction personnel have dealt with the separated area (whether by adjusting the distance by moving the screw or filling the separated area with soil, concrete, etc.), the annular contact 200 is reset. At this time, the second elastic element 700 is compressed, and the first elastic element 520 can pull back the first annular plate 510 and the indicator 300 connected to the other side of the first annular plate 510, so as to wait for the next separation to issue an indicator.
[0052] By setting the first annular plate 510, which can connect the prompting member 300 and the first elastic member 520, the prompting member 300 and the first annular plate 510 can be displaced together when the annular contact member 200 is displaced, and the first elastic member 520 is stretched at the same time. After the annular contact member 200 is reset, the first elastic member 520 will pull the first annular plate 510 and the prompting member 300 back because the second elastic member 700 is compressed.
[0053] Furthermore, in order to enable the indicator 300 to change color during the process of the second elastic member 700 driving the annular contact 200 to adhere to the soil, as a preferred embodiment of this utility model, please refer to [link to relevant documentation]. Figures 1-6 The surface of the prompting element 300 near the first annular plate 510 is provided with several color indicator labels 301 of different colors, and the end of the prompting element 300 away from the first annular plate 510 is fixedly connected to the side of the annular contact element 200 away from the soil.
[0054] Specifically, by setting several color indicator labels 301 of different colors (e.g., colorless under normal circumstances, but changing from small to large color after a gap occurs: green, yellow, red, etc.) at one end of the indicator 300 near the first annular plate 510, the color indicator labels 301 of different colors can provide different prompts when the annular contact 200 pulls the indicator 300 and causes displacement, so as to remind the construction personnel of the size of the gap.
[0055] Furthermore, in addition to the screw, annular contact 200, second elastic element 700, prompting element 300, and elastic component 500, the mounting structure also includes at least two slide rails 400, which can limit the movement direction of the elastic component 500.
[0056] To achieve the function of the slide rail 400 described above, as a preferred embodiment of this utility model, please refer to... Figures 1-5The inner wall of the annular contact 200 is provided with at least one second sliding groove 201, the inner wall of the first annular plate 510 is provided with at least one first sliding groove 511, the outer wall of the sensor housing 100 is fixedly connected to the slide rail 400, and the second sliding groove 201 and the first sliding groove 511 are slidably connected to the two slide rails 400 respectively.
[0057] Specifically, by providing a second groove 201 and a first groove 511 on the inner walls of the annular contact 200 and the first annular plate 510, and cooperating with the slide rail 400 on the outer wall of the sensor housing 100, the annular contact 200 and the first annular plate 510 can only move in the direction of the groove and the slide rail 400, and will not "twist".
[0058] Furthermore, in addition to the screw, annular contact 200, second elastic element 700, indicator 300, elastic component 500, and slide rail 400, the installation structure also includes a support component 600, which can support the indicator 300 and can also change the direction of the indicator 300.
[0059] To achieve the function of the aforementioned support component 600, as a preferred embodiment of this utility model, please refer to... Figures 3-5 The support assembly 600 includes a second annular plate 610 and an annular column 620. The inner wall of the second annular plate 610 is fixedly connected to the outer wall of the sensor housing 100. The two sides of the second annular plate 610 are fixedly connected to the first elastic member 520 and the second elastic member 700, respectively. The end of the second elastic member 700 away from the second annular plate 610 is fixedly connected to the side of the annular contact member 200 away from the soil. The annular column 620 is a hollow column. The side of the second annular plate 610 close to the first elastic member 520 is fixedly connected to one end of the annular column 620. The other end of the annular column 620 is located at the corner of the prompting member 300.
[0060] Specifically, by setting the second annular plate 610, support can be provided for the first elastic member 520 and the second elastic member 700, ensuring that one end of the first elastic member 520 and the second elastic member 700 cannot move.
[0061] By setting a hollow annular column 620, firstly, its hollow shape does not hinder the normal operation of the first elastic element 520; secondly, as... Figure 4 As shown, because the end of it away from the second annular plate 610 is pressed against the corner of the prompting element 300, the prompting element 300 can be turned in this way, and the prompting element 300 can also be guaranteed not to collapse.
[0062] This utility model also provides the following technical solution: a pressure sensor for construction monitoring, including a sensor housing 100, with a cavity formed inside the sensor housing 100, and all the components required for the pressure sensor are located inside the cavity. The pressure sensor has a detection end facing the soil.
[0063] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
