DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] See also Figure 1-11 As shown, an embodiment of the present invention provides an installation device for an earth pressure box in a side wall pipe of an anti-sliding pile, the installation device comprising a main pipe 1, a travel push pipe 2, an earth pressure measurement assembly 3, a guide rod 4 and a plurality of positioning support assemblies 5, wherein: In order to ensure the centering of the entire device, the main tube 1 includes a first tubular body 11 and a second tubular body 12 which are coaxially connected, and the soil pressure measurement assembly 3 is limitedly installed inside one end of the second tubular body 12; the travel push tube 2 is limitedly sleeved on the first tubular body 11 to provide a relative movement mechanism for the positioning support assembly 5.

[0019] In order to prevent the displacement of the earth pressure box during the installation process, for example, if the initial position of the earth pressure box is not stable enough, the subsequent pre-pressure may be affected. For this reason, in the initial stage of installation, in this embodiment, a plurality of positioning support components 5 are evenly arranged on the outer circumference of the main pipe 1, and the side of the positioning support component 5 away from the main pipe 1 is supported on the inner wall of the reserved pipe (not shown in the figure), and the other side is suitable for circumferential positioning on the outer circumferential wall of the main pipe 1 and the travel push pipe 2; the positioning support component 5 is suitable for adjusting the positioning reference of the main pipe 1, thereby limiting the vertical plane position of the earth pressure measurement component 3. In this way, the positioning reference of the main pipe 1 is adjusted by the positioning support component 5, thereby limiting the vertical plane position of the earth pressure measurement component 3. As the installation process proceeds, even if the reserved pipe may have a certain degree of irregular shape or a small amount of debris inside, the positioning support component 5 can ensure that the earth pressure measurement component 3 is always in a precise vertical plane position through its own adjustment adaptability, thereby ensuring the accuracy of subsequent earth pressure measurement.

[0020] As the installation process proceeds, the guide rod 4 is threadedly arranged in the main tube 1 along one end of the first tubular body 11 away from the second tubular body 12, and the guide rod 4 is suitable for being screwed in to push the earth pressure measurement assembly 3 out of the second tubular body 12 to the soil position, and applying the same pre-pressure relative to the corresponding layout point to the earth pressure measurement assembly 3. By rotating the guide rod 4 to make it gradually screwed into the main tube 1, this process can smoothly push out the earth pressure measurement assembly 3. Since the guide rod 4 is a threaded connection, its movement is stable and controllable, and it will not cause sudden impact or position displacement to the earth pressure measurement assembly 3, ensuring the stability of the earth pressure measurement assembly 3 during the ejection process.

[0021] In addition, after the earth pressure measuring assembly 3 is pushed out to the soil, by accurately controlling the screwing degree of the guide rod 4, a uniform and appropriate pre-pressure can be applied to the earth pressure measuring assembly 3 according to predetermined requirements. Accurate application of pre-pressure can ensure a good contact state between the earth pressure measuring assembly 3 and the surrounding soil, so that it can truly reflect the changes in soil pressure.

[0022] Therefore, the soil pressure box installation device in the side wall tube of the anti-sliding pile can effectively ensure the positioning accuracy, stable installation and accurate pre-pressure application of the soil pressure measurement component 3 during the installation process, which is of great significance for improving the accuracy of soil pressure measurement in anti-sliding pile construction.

[0023] It should be pointed out that the reserved pipe has an irregular shape or has debris inside, and the traditional fixing method may not be able to adapt to these situations. In the actual anti-slip pile construction environment, the reserved pipe may be slightly deformed due to minor errors in the early construction or the initial effect of soil pressure. The positioning support component 5 can be fine-tuned in time according to the actual shape of the inner wall of the reserved pipe, so that the main pipe 1 maintains a stable axial position, thereby ensuring the initial position accuracy of the soil pressure measurement component 3 during the installation process.

[0024] In addition, when monitoring the soil pressure of anti-sliding piles, soils at different depths have different characteristics such as density and water content, and the corresponding deployment points require different pre-pressures to ensure accurate measurement of the soil pressure box. Through the precise control of the guide rod 4, the device can accurately apply the corresponding pre-pressure to each deployment point, thereby adapting to the complex underground soil environment and improving the reliability of the entire anti-sliding pile monitoring system.

[0025] Specifically, see Figure 2 , 4 As shown, in the embodiment of the present invention, each positioning support assembly 5 includes a tube wall support plate 51, a first support rod 52, a second support rod 53, two first protrusions 54 and a second protrusion 55 and a roller 56, wherein: The two first protrusions 54 are respectively hinged at the two ends of the first support rod 52, one of the first protrusions 54 is fixed on the outer circumference of the travel push tube 2, and the other first protrusion 54 is fixed on one side of the inner wall of the tube wall support plate 51. The second protrusion 55 and the roller 56 are respectively hinged at the two ends of the second support rod 53, and the second protrusion 55 is fixed on the outer circumferential wall of the first tubular body 11. The other side of the inner wall of the tube wall support plate 51 is provided with a guide rail 511 extending in a direction parallel to the axis of the main tube 1, and the roller 56 is suitable for limited sliding in the guide rail 511. The first support rod 52 and the second support rod 53 are arranged in parallel and staggered.

[0026] During operation, each positioning support assembly 5 realizes flexible and stable positioning support for the main pipe 1 through its unique structure. The pipe wall support plate 51 is a component that directly contacts the inner wall of the reserved pipe, and one side of the inner wall is connected to the first support rod 52, while the other side of the outer wall is supported on the inner wall of the reserved pipe. When the position of the main pipe 1 needs to be adjusted, the first support rod 52 and the second support rod 53 are arranged in parallel and staggered manner and are cleverly connected through protrusions and rollers 56 and other components. They can automatically adjust the angle and the degree of tightening according to the shape of the inner wall of the reserved pipe and the stress condition of the main pipe 1, ensuring that the main pipe 1 always maintains a stable position in the reserved pipe, effectively preventing the main pipe 1 from shaking or deflecting during installation and measurement, thereby ensuring the measurement accuracy of the soil pressure measurement assembly 3.

[0027] When the travel push tube 2 moves relative to the main tube 1, the first support rod 52 will be subjected to the force from the first protrusion 54, thereby driving the second support rod 52 and the roller 56 to move together, and then driving the tube wall support plate 51 to move accordingly. The roller 56 slides in the guide rail 511 of the tube wall support plate 51, and the direction of the guide rail 511 is parallel to the axis of the main tube 1. In this way, the movement of the roller 56 is along the axial direction of the main tube 1, and the radial movement of the tube wall support plate 51 realizes the tightening or loosening action. In this way, through the linkage of the support rod and the roller, the tube wall support plate 51 can be stably supported on the inner wall of the reserved tube, thereby ensuring the stability and position accuracy of the main tube 1 in the axial direction.

[0028] Considering that the position of the earth pressure measurement assembly 3 is determined by the main pipe 1, and the stability of the main pipe 1 depends on the positioning support assembly, if the positioning support assembly 5 can accurately support the inner wall of the reserved pipe, the axis position of the main pipe 1 can be ensured to be stable, thereby ensuring the vertical plane position accuracy of the earth pressure measurement assembly 3.

[0029] Therefore, through the linkage of the support rod, roller and guide rail, the inner wall of the reserved tube is adaptively tightened, the stability and accuracy of positioning are improved, and at the same time friction and wear are reduced, and the service life is extended.

[0030] Specifically, see Figure 2 , 4As shown, in the embodiment of the present invention, the travel push tube 2 includes a push tube body 21 and a flange 22 which are coaxially connected in sequence, and the push tube body 21 and the flange 22 are sleeved on the first tubular body 11. This coaxial design ensures the stability of the travel push tube 2 during movement and avoids shaking or jamming caused by eccentricity. The flange 22 is located on the side away from the second tubular body 12. The inner diameter of the push tube body 21 and the flange 22 is larger than the outer diameter of the first tubular body 11, and the outer diameter of the push tube body 21 is smaller than the outer diameter of the flange 22. This not only ensures the smooth movement of the travel push tube 2, but the larger outer diameter of the flange 22 can provide sufficient support and connection interface when needed, so that the travel push tube 2 can play the maximum function in a limited space and meet the needs of anti-slip pile installation and soil pressure measurement.

[0031] Specifically, see Figure 2 , 4 As shown, in an embodiment of the present invention, the travel push tube 2 also includes a hexagonal nut 23, and a first external thread 113 is provided on the outer circumference of one side of the first tubular body 11 away from the second tubular body 12, and the hexagonal nut 23 is suitable for being threadedly connected to the first external thread 113 to axially limit the travel push tube 2 on the first tubular body 11.

[0032] During installation and use, the hexagonal nut 23 is threadedly connected to the first external thread 113 on the first tubular body 11, so that the travel push tube 2 can be stably axially limited on the first tubular body 11. This limiting method is simple and reliable, and can effectively prevent the travel push tube 2 from unnecessary movement or falling off in the axial direction. During the installation of the soil pressure measurement component 3 or during the construction of anti-sliding piles, the entire device will be affected by various external forces, such as soil pressure, the gravity of the device itself, and the impact force generated during operation. The tightening effect of the hexagonal nut 23 can ensure that the travel push tube 2 always remains in the correct position and will not be displaced due to external forces, thereby ensuring the stability and reliability of the entire device.

[0033] Specifically, see Figure 1 , 6 As shown, in an embodiment of the present invention, the guide rod 4 includes a guide rod body 41, a second external thread 42 is provided on the outer circumference of one side of the guide rod body 41 close to the second tubular body 12, and a first internal thread 111 is provided on the inner circumference of one side of the first tubular body 11 close to the second tubular body 12, and the first internal thread 111 is threadedly connected with the second external thread 42 in a matching manner.

[0034] When the earth pressure measuring assembly 3 needs to be ejected from the second tubular body 12 to the soil position, the extension length of the guide rod 4 can be accurately controlled by rotating the guide rod 4 and utilizing the transmission characteristics of the thread, thereby realizing accurate ejection of the earth pressure measuring assembly 3. At the same time, after the earth pressure measuring assembly 3 is ejected, the guide rod 4 is continuously rotated, so that the same pre-pressure relative to the corresponding arrangement point can be applied to the earth pressure measuring assembly 3. The application of such pre-pressure can also be ensured to be consistent through the precise control of the thread, ensuring a good contact state between the earth pressure measuring assembly 3 and the surrounding soil, thereby improving the accuracy of earth pressure measurement.

[0035] Specifically, see Figure 1 , 2 As shown, in the embodiment of the present invention, the earth pressure measurement assembly 3 includes an earth pressure box compartment 31, an earth pressure box 32 and a first locking member 33, wherein: The earth pressure box bin 31 is axially limited on the inner hole of the second tubular body 12. This limiting method can ensure the stable position of the earth pressure box bin 31 in the axial direction. The earth pressure box bin 32 is installed in the earth pressure box bin 31. The earth pressure box bin 31 includes a bin body 311. A plurality of first locking holes 313 are evenly opened on the outer circumference of the bin body 311. The first locking member 33 is suitable for being threadedly connected in the first locking holes 313 to circumferentially position the earth pressure box 32 in the earth pressure box bin 31. This arrangement enables the earth pressure box 32 to be accurately positioned at a predetermined position during installation, and measurement errors will not be caused by shaking or displacement during installation.

[0036] Specifically, see Figure 2 , 6 As shown, in the embodiment of the present invention, a plurality of evenly distributed limiting grooves 121 are provided on the inner hole of the second tubular body 12, and a plurality of bosses matching the limiting grooves 121 are correspondingly provided on the outer circumference of the earth pressure box 31, and the bosses are matchingly connected with the limiting grooves 121.

[0037] When installing the earth pressure measurement assembly 3, the boss on the outer circumference of the earth pressure box 31 is matched with the limit groove 121 on the inner hole of the second tubular body 12. This arrangement can accurately position the earth pressure box 31 circumferentially to prevent it from rotating during installation and measurement.

[0038] It is understandable that, in the construction of anti-sliding piles, the circumferential position of the earth pressure box 31 is crucial to the accuracy of the measurement data, because the direction and magnitude of the earth pressure are often closely related to the distribution of the soil and the stress state of the anti-sliding piles. Through this limiting structure, it can be ensured that the earth pressure box 31 always maintains the correct circumferential position, thereby ensuring the accuracy of the earth pressure measurement.

[0039] Specifically, see Figure 1 , 7 As shown in Figure 9, in an embodiment of the present invention, a conical groove 312 is provided at the center of one end of the magazine body 311 facing the second tubular body 12, and the guide rod 4 also includes a conical head 43 arranged at the center of the end of the guide rod body 41, and the conical head 43 is suitable for being inserted into the conical groove 312.

[0040] Therefore, this conical structure can provide precise centering and guiding functions to ensure the coaxiality between the guide rod 4 and the earth pressure box chamber 31. During the ejection process, the cooperation between the conical head 43 and the conical groove 312 can guide the earth pressure box 32 to move in the correct direction, avoiding the earth pressure box 32 from tilting or deflecting during the ejection process, thereby ensuring that the earth pressure box 32 can accurately reach the predetermined measurement position.

[0041] Specifically, see Figure 1 , 2 As shown, in the embodiment of the present invention, the guide rod 4 further comprises a hexagonal nut head 44 disposed at one end of the guide rod body 41 away from the conical head 43 , and the hexagonal nut head 44 is suitable for a torque wrench to apply torque to the guide rod 4 .

[0042] The hexagonal nut head 44 is designed at the end of the guide rod body 41 away from the conical head 43, providing a standard hexagonal interface for the torque wrench, so that the construction personnel can use the torque wrench to accurately apply torque to the guide rod 4. In the process of ejection and pre-pressure application, accurate torque control is very important, which directly affects the ejection distance and pre-pressure of the earth pressure box 32. By using a standard torque wrench, it can be ensured that the guide rod 4 is accurately screwed in or out according to the design requirements, thereby achieving accurate ejection of the earth pressure box 32 and accurate application of pre-pressure. See also Fig.12 As shown, an embodiment of the present invention further provides an installation method for an anti-sliding pile side wall in-pipe earth pressure box installation device, the installation method comprising the steps of: Step S 1 : Position the earth pressure box 32 in the earth pressure box bin 31 in cooperation with the first locking member 33, and slide the earth pressure box bin 31 along the limiting groove 121 in the second tubular body 12 to install one end of the main body tube 1; Step S 2 : Taking the main tube 1 as a reference, a plurality of positioning support components 5 are evenly arranged in the circumferential direction of the main tube 1, the travel push tube 2 and the reserved tube; Step S 3: Control the travel push tube 2 to push toward the end close to the soil pressure box 32, so that the first support rod 52 and the second support rod 53 cross to support the pipe wall support plate 51, and during the supporting process, the roller 56 is always in contact with the rear of the guide rail 511 until the pipe wall support plate 51 is completely circumferentially positioned on the inner wall of the reserved pipe, and the hexagonal nut 23 is fastened to the first external thread 113 of the main pipe 1; Step S 4 : Use the torque wrench to control the guide rod 4 to screw into the main pipe 1, push the earth pressure box 32 along the main pipe 1 toward the soil position, and apply a preset pressure to the earth pressure box 32 Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
