[0009] The following describes in detail the configurations for implementing the piles relating to this application (hereinafter referred to as "embodiments"). Note that these embodiments do not limit the piles relating to this application. [Examples]

[0010] Figure 1 is a schematic diagram showing the embedded state of the pile according to the embodiment. Figure 2 is a schematic diagram of the embedded state of the pile according to the embodiment viewed from above.

[0011] (Pile configuration) As shown in Figures 1 and 2, the pile 1 of the embodiment comprises a rod-shaped member 5 that is driven into the ground, and a reinforcing member 6 that is extendable and retractable from the outer surface 4a of the embedded portion 4 of the rod-shaped member 5 that is buried in the ground. When the embedded portion 4 of the rod-shaped member 5 is buried in the ground, the upper end portion 5a of the rod-shaped member 5 is embedded so that it protrudes from the ground surface and is exposed above ground.

[0012] (Key part of the pile) Figure 3 is a schematic longitudinal cross-sectional view showing the main part of the pile 1 of the embodiment. As shown in Figure 3, the rod-shaped member 5 is formed in a cylindrical shape having a central hole 7 in which the reinforcing member 6 is housed, and for example, a metal pipe is used.

[0013] The reinforcing member 6 is formed of, for example, a metal material, and has a stem portion 11 provided along the longitudinal direction of the rod-shaped member 5 in the central hole 7, and a plurality of branch portions 12 that are folded with respect to the stem portion 11 and accommodated in the central hole 7.

[0014] A plurality of through holes 14 communicating with the central hole 7 are provided on the outer peripheral surface 4a of the rod-shaped member 5. Each folded branch portion 12 has its tip inserted into each through hole 14, and each branch portion 12 is configured to be able to project from the outer peripheral surface 4a through each through hole 14.

[0015] The stem portion 11 of the reinforcing member 6 is formed in a rod shape and is provided so as to be movable in the longitudinal direction of the rod-shaped member 5 within the central hole 7. The stem portion 11 has, for example, an end portion 11a that protrudes from the upper end portion 5a of the rod-shaped member 5 to the ground, and is moved in the longitudinal direction of the rod-shaped member 5 while holding the end portion 11a.

[0016] Each branch portion 12 of the reinforcing member 6 is a rod-shaped portion that extends from the outer peripheral surface 4a of the rod-shaped member 5 into the ground and bites into the ground. By the branch portion 12 of the reinforcing member 6 biting into the ground, the stability of the embedded state of the rod-shaped member 5 in the pile 1 is enhanced.

[0017] As an example, the proximal ends 12a of the plurality of branch portions 12 are formed integrally with the stem portion 11 and are folded by elastically deforming with respect to the stem portion 11. Further, for example, the proximal ends 12a of the plurality of branch portions 12 may be rotatably supported by the stem portion 11 and folded against the elastic force of a spring (not shown) attached to the proximal ends 12a. And the pile 1 is configured such that by pulling up the end portion 11a of the stem portion 11 from the upper end portion 5a of the rod-shaped member 5, within the central hole 7 of the rod-shaped member 5, the branch portion 12 spreads in a direction away from the stem portion 11 and can extend toward the ground through the through hole 14 of the rod-shaped member 5.

[0018] The reinforcing member 6 has a plurality of branch portions 12 provided at intervals in the longitudinal direction of the trunk portion 11. For this reason, as shown in FIG. 1, in the embedded portion 4 of the rod-shaped member 5, the plurality of branch portions 12 extend side by side in the longitudinal direction of the rod-shaped member 5 and extend into the ground. Thereby, since each branch portion 12 bites into the ground in the longitudinal direction of the rod-shaped member 5, the stability of the embedded state of the rod-shaped member 5 in the pile 1 is enhanced. Although not shown, the branch portion 12 may be formed with a protrusion that tapers in the direction opposite to the direction extending toward the ground, that is, a so-called barb, which can enhance the biting into the ground.

[0019] As shown in FIG. 2, the reinforcing member 6 is provided such that a plurality of branch portions 12 extend radially toward the ground around the trunk portion 11. For example, the plurality of branch portions 12 are arranged on the outer peripheral surface 4a of the rod-shaped member 5 at intervals around the central hole 7. For this reason, in the embedded portion 4 of the rod-shaped member 5, the plurality of branch portions 12 bite radially into the surrounding ground centered on the rod-shaped member 5, so that the stability of the embedded state of the rod-shaped member 5 in the pile 1 is enhanced.

[0020] Also, each branch portion 12 is arranged to extend into the ground from a position separated from the ground surface by a predetermined depth, for example, 1 [m] or more, in the longitudinal direction (vertical direction) of the embedded portion 4 of the rod-shaped member 5, preventing changes such as the extended branch portion 12 protruding from the ground surface or the ground surface being raised by the extended branch portion 12.

[0021] Also, the branch portion 12 of the reinforcing member 6 extends obliquely from the outer peripheral surface 4a of the rod-shaped member 5 with respect to the ground surface. The branch portion 12 in the embodiment extends obliquely upward toward the ground surface, but may extend obliquely downward so as to move away from the ground surface.

[0022] The rod-shaped member 5 has a receiving portion 16 into which the branch portions 12 of the reinforcing member 6 extending from adjacent piles 1 are inserted when multiple piles 1 are embedded in the ground in a line. The receiving portion 16 is, for example, a recess formed on the outer circumferential surface 4a of the rod-shaped member 5. The receiving portion 16 has a guide surface 16a that serves as a guide portion to guide the tip of the branch portion 12 of the reinforcing member 6 (see Figure 5). The guide surface 16a of the receiving portion 16 guides the tip of the branch portion 12 that extends diagonally upward in the ground and engages with the receiving portion 16. In this way, when adjacent piles 1 are embedded with each other, the branch portions 12 and the receiving portion 16 engage with each other, connecting multiple piles 1, and thus increasing the stability of the embedded state of each pile 1.

[0023] Furthermore, the through-hole 14 has a guide surface 14a that serves as a guide to guide the direction in which the branch portion 12 of the reinforcing member 6 extends toward the ground (see Figure 5). The through-hole 14 is formed, for example, in the embedded portion 4 of the rod-shaped member 5, so as to penetrate diagonally upward from the inner surface of the central hole 7 of the rod-shaped member 5 toward the outer surface 4a. As a result, the branch portion 12 is guided toward the appropriate direction as it passes through the through-hole 14, so that, as will be described later, the branch portion 12 extending from one pile 1 to another pile 1 can be smoothly inserted into the receiving portion 16 between adjacent piles 1, and the piles 1 can be connected to each other.

[0024] (Pile embedding status) Figure 4 is a schematic diagram showing the embedded state of multiple piles 1 in an embodiment. Figure 5 is a longitudinal cross-sectional view illustrating the extension of the reinforcing member 6 in an embodiment.

[0025] As shown in Figure 4, three piles 1 are driven into the ground at predetermined intervals from each other, and the branch portions 12 of the reinforcing members 6 extending from the rod-shaped members 5 of each pile 1 intersect with each other, and the receiving portion 16 of the adjacent rod-shaped member 5 engages with the branch portion 12.

[0026] As shown in Figure 5, after the pile 1 is driven into the ground, the end 11a of the main body 11 of the reinforcing member 6 is pulled up from the upper end 5a of the rod-shaped member 5. As the main body 11 rises, each branch 12 of the reinforcing member 6, which was folded inside the central hole 7 of the rod-shaped member 5, extends into the ground through the through hole 14. As a result, each branch 12 of the reinforcing member 6 bites into the ground.

[0027] The state in which the pile 1 configured as described above is used will now be explained. Figure 6 is a schematic diagram showing the state in which a container is installed on the pile 1 of the embodiment.

[0028] As shown in Figure 6, multiple piles 1 are driven into the ground, and after the reinforcing members 6 of each pile 1 extend into the ground, stabilizing the embedded state of each pile 1, a container 18 is installed on the upper end 5a of each rod-shaped member 5 located above ground, for example, via a base 17. For example, the bottom of the container 18 is fastened to the base 17, which is positioned across the upper end 5a of each pile 1, by fixing fittings (not shown). The container 18 can house, for example, information storage devices such as network servers or storage tanks for ammonia, but the objects to be housed in the container 18 are not limited.

[0029] In this embodiment, by installing the container 18 on the pile 1, the container 18 can be firmly fixed to the ground via the pile 1, thereby increasing the stability of the fixed state, compared to when the container 18 is installed directly on the ground.

[0030] Furthermore, the multiple containers 18 installed on the pile 1 of this embodiment may be connected to each other, thereby increasing the stability of the fixed state of the multiple containers 18. Also, the pile 1 of this embodiment is not limited to containers 18, but may be applied to install various structures on the ground.

[0031] As described above, the pile 1 of the embodiment comprises a rod-shaped member 5 that is driven into the ground, and a reinforcing member 6 that is extendable and retractable from the outer surface 4a of the embedded portion 4 of the rod-shaped member 5 that is buried in the ground. As a result, the embedded state of the embedded portion 4 of the pile 1 becomes stronger, and stability can be improved when it is driven into the ground.

[0032] Furthermore, the reinforcing member 6 in the pile 1 of this embodiment has a rod-shaped portion (branch portion 12) that extends into the ground from the outer circumferential surface 4a of the rod-shaped member 5 and bites into the ground. This allows the rod-shaped portion to smoothly bite into the ground when the reinforcing member 6 extends into the ground.

[0033] Furthermore, in the embodiment of the pile 1, the reinforcing member 6 extends diagonally from the outer circumferential surface 4a of the rod-shaped member 5 toward the ground surface. This allows the reinforcing member 6 to be driven into the ground along the longitudinal direction (vertical direction) of the embedded portion 4 of the rod-shaped member 5, thereby strengthening the embedded state of the embedded portion 4.

[0034] Furthermore, the rod-shaped member 5 in the pile 1 of this embodiment has a receiving portion 16 into which a reinforcing member 6 extending from another adjacent pile 1 is inserted. As a result, the reinforcing member 6 and the receiving portion 16 engage with each other, connecting the piles 1, thereby strengthening the embedded state of each pile 1 and improving stability when driven into the ground.

[0035] Furthermore, the receiving portion 16 of the rod-shaped member 5 in the pile 1 of this embodiment is a recess formed on the outer circumferential surface 4a of the embedded portion 4 of the rod-shaped member 5. This allows the receiving portion 16 to be formed simply without hindering the rod-shaped member 5 from digging into the ground when the pile 1 is driven into the ground.

[0036] Furthermore, in the pile 1 of this embodiment, a guide surface 16a is formed on the receiving portion 16 of the rod-shaped member 5 to guide the reinforcing member 6. This allows the reinforcing member 6 and the receiving portion 16 to engage smoothly.

[0037] Furthermore, in the pile 1 of this embodiment, the rod-shaped member 5 is formed in a cylindrical shape having a central hole 7 in which the reinforcing member 6 is housed. The reinforcing member 6 has a main body 11 provided along the longitudinal direction of the rod-shaped member 5 within the central hole 7, and branch portions 12 that are folded relative to the main body 11 and housed within the central hole 7, with the branch portions 12 extending into the ground from the outer circumferential surface 4a of the embedded portion 4 of the rod-shaped member 5. This makes it possible to easily realize a structure in which the reinforcing member 6 extends into the ground from the embedded portion 4 of the rod-shaped member 5.

[0038] Furthermore, in the pile 1 of this embodiment, the reinforcing member 6 has multiple branches 12 provided at intervals along the longitudinal direction of the main body 11. As a result, multiple branches 12 extend into the ground along the longitudinal direction of the embedded portion 4 of the rod-shaped member 5, thereby strengthening the embedded state of the pile 1 and improving the stability of the pile 1 driven into the ground.

[0039] Furthermore, in the pile 1 of this embodiment, the reinforcing member 6 is provided with multiple branches 12 that extend radially into the ground from the main trunk 11. As a result, the multiple branches 12 extend into the ground from around the embedded portion 4 of the rod-shaped member 5, thereby strengthening the embedded state of the pile 1 and improving its stability when driven into the ground.

[0040] Furthermore, the rod-shaped member 5 in the pile 1 of this embodiment has a through hole 14 through which the branch portion 12 of the reinforcing member 6 passes, and a guide surface 14a is formed in the through hole 14 to guide the direction in which the branch portion 12 extends into the ground. As a result, the branch portion 12 of the reinforcing member 6 can be extended in the appropriate direction into the ground, so that the branch portion 12 can be properly driven into the ground and the stability of the pile 1 driven into the ground can be improved.

[0041] Furthermore, in the embodiment, a container 18 is installed on the upper end 5a of the rod-shaped member 5 of the pile 1 that is exposed to the ground. This improves the stability of the installed state of the container 18.

[0042] Furthermore, the reinforcing member 6 may extend its branches 12 themselves relative to the main trunk 11, causing the branches 12 to penetrate the ground. For example, the branches 12 may be driven by a motor to extend and penetrate the ground.

[0043] This disclosure includes the following aspects:

[0044] (Note) The pile system according to an embodiment of the present invention is a pile system for stably installing a container on the ground. This pile system has a rod-shaped member that is driven into the ground and a reinforcing member that is extendable and retractable from the side of the pile buried in the ground. This pile system is stabilized by the reinforcing member gripping the soil, and the container can be firmly installed. Furthermore, the reinforcing member extends diagonally across the ground surface, making it difficult for the pile to come out of the ground. In addition, the reinforcing member can extend to other nearby piles and be inserted into receiving parts provided on those other piles, thereby fastening the piles together and making them stronger. For example, the pile system has a rod-shaped member that is driven into the ground. This rod-shaped member has a reinforcing member that is extendable and retractable from the side of the portion buried in the ground. The reinforcing member stabilizes the pile by gripping the soil. For example, the reinforcing member can extend diagonally across the ground surface. This makes it difficult for the pile to come out of the ground. In addition, the reinforcing member can extend to other nearby piles and be inserted into receiving parts provided on those other piles. This fastens the piles together and makes them stronger. This makes the container installation more stable and improves safety. The pile system allows for a more secure installation of the container.

[0045] The pile system according to this embodiment comprises a rod-shaped member and a reinforcing member. The rod-shaped member is driven into the ground. The rod-shaped member is made of a strong material such as steel or concrete. By being driven into the ground, the rod-shaped member forms the foundation of the pile. The reinforcing member is extendable and retractable from the side of the portion of the rod-shaped member that is buried in the ground. The reinforcing member is made of a metal arm or frame, for example. The reinforcing member stabilizes the pile by gripping the soil. For example, the reinforcing member can firmly grip the soil underground. Also, since the reinforcing member is extendable and retractable, it can be adjusted to an appropriate length depending on the conditions underground. Furthermore, by gripping the soil underground, the reinforcing member makes it difficult for the pile to come out of the ground. For example, the reinforcing member improves the stability of the pile by firmly biting into the soil underground. As a result, the pile is stabilized by the reinforcing member gripping the soil.

[0046] The pile system according to this embodiment comprises a rod-shaped member and a reinforcing member. The rod-shaped member is driven into the ground. The rod-shaped member is made of a strong material such as steel or concrete. Steel has high tensile strength and durability, and concrete has excellent compressive strength, so using these materials makes the foundation of the pile very strong. The rod-shaped member becomes the foundation of the pile when driven into the ground. When driving it in, a special driving machine is used to ensure that it is inserted deep into the ground. The depth and angle of driving are adjusted according to the characteristics of the ground and the design of the building. The reinforcing member is extendable and retractable from the side of the portion of the rod-shaped member that is buried in the ground. The reinforcing member is made of a metal arm or frame, for example. The metal arm has high rigidity and durability and can withstand long-term use underground. The reinforcing member stabilizes the pile by gripping the soil. Specifically, the reinforcing member can firmly grip the soil underground. Since the reinforcing member is extendable and retractable, it can be adjusted to an appropriate length according to the conditions underground. For example, if the soil underground is soft, the reinforcing member is extended to grip the soil over a wide area, ensuring the stability of the pile. On the other hand, if the soil underground is hard, the reinforcing member is shortened to allow it to firmly penetrate the soil. Furthermore, by gripping the soil underground, the reinforcing member makes it difficult for the pile to come loose. For example, the reinforcing member improves the stability of the pile by firmly penetrating the soil underground. Because the pile is stabilized by the reinforcing member gripping the soil, the pile will not move even when subjected to external forces such as earthquakes or strong winds, ensuring the safety of the building. In addition, since the reinforcing member is made of a material that is resistant to moisture and chemical substances in the soil, it can maintain its function over a long period of time. As a result, the pile is stabilized by the reinforcing member gripping the soil, and the foundation of the building becomes stronger.

[0047] The reinforcing member can extend diagonally from the side of the rod-shaped member toward the ground surface. For example, by extending diagonally toward the ground surface, the reinforcing member makes it more difficult for the pile to come loose from the ground. For example, by extending diagonally toward the ground surface, the reinforcing member improves the stability of the pile. Furthermore, by extending diagonally toward the ground surface, the reinforcing member makes it more difficult for the pile to come loose from the ground. For example, by extending diagonally toward the ground surface, the reinforcing member improves the stability of the pile. This makes it more difficult for the pile to come loose from the ground as the reinforcing member extends diagonally toward the ground surface.

[0048] The reinforcing member can extend to other nearby piles and be inserted into receiving portions provided on those other piles. For example, by extending the reinforcing member to other nearby piles and inserting it into receiving portions provided on those other piles, the piles are fastened together. The reinforcing member, for example, by extending to other nearby piles and inserting it into receiving portions provided on those other piles, improves the stability of the piles. Furthermore, the reinforcing member can extend to other nearby piles and be inserted into receiving portions provided on those other piles, fastening the piles together. For example, by extending the reinforcing member to other nearby piles and inserting it into receiving portions provided on those other piles, the stability of the piles is improved. As a result, the piles are fastened together by the insertion of the reinforcing member into the receiving portions provided on other piles, making them stronger.

[0049] The reinforcing member is expandable and expandable, and can stabilize the pile by gripping the soil underground. The reinforcing member is, for example, expandable and expandable, and can stabilize the pile by gripping the soil underground. The reinforcing member is, for example, expandable and expandable, and can improve the stability of the pile by gripping the soil underground. Furthermore, the reinforcing member is expandable and can stabilize the pile by gripping the soil underground. For example, the reinforcing member is expandable and expandable, and can improve the stability of the pile by gripping the soil underground. Thus, the reinforcing member is expandable and expandable, and can stabilize the pile by gripping the soil underground.

[0050] The piles are for installing containers, and the reinforcing members grip the soil, allowing the containers to be firmly installed. For example, the piles are for installing containers, and the reinforcing members grip the soil, allowing the containers to be firmly installed. For example, the piles are for installing containers, and the reinforcing members grip the soil, improving the stability of the containers. Furthermore, the piles are for installing containers, and the reinforcing members grip the soil, allowing the containers to be firmly installed. For example, the piles are for installing containers, and the reinforcing members grip the soil, improving the stability of the containers. This allows the containers to be firmly installed by the reinforcing members gripping the soil.

[0051] The system according to the embodiment is not limited to the example described above, and various modifications are possible, for example, as follows.

[0052] The container installation system can also be equipped with a vibration absorber. The vibration absorber absorbs vibrations generated when the container is installed, improving the stability of the container. For example, the vibration absorber can absorb vibrations using rubber pads. The rubber pads are placed between the bottom of the container and the top of the pile to effectively absorb vibrations. Alternatively, the vibration absorber can absorb vibrations using springs. The springs are placed between the bottom of the container and the top of the pile to mitigate vibrations. Furthermore, the vibration absorber can absorb vibrations using dampers. The dampers are placed between the bottom of the container and the top of the pile to reduce vibrations. Thus, the vibration absorber can absorb vibrations using any of the methods—rubber pads, springs, or dampers—improving the stability of the container.

[0053] The container installation system may also be equipped with a temperature control unit. This unit adjusts the temperature inside the container, allowing items to be stored at an appropriate temperature. For example, the temperature control unit can cool the inside of the container using a cooling device. The cooling device is installed inside the container and lowers the internal temperature by circulating a refrigerant. Alternatively, the temperature control unit can heat the inside of the container using a heating device. The heating device is installed inside the container and raises the internal temperature using an electric heater or hot water. Furthermore, the temperature control unit can maintain a constant temperature inside the container using insulation. Insulation is installed on the walls of the container to protect the interior from external temperature fluctuations. Thus, the temperature control unit can adjust the temperature inside the container using any of the following methods—cooling, heating, or insulation—enabling proper storage of items.

[0054] The container installation system can also be equipped with a security unit. The security unit provides functions to protect the contents of the container from theft and unauthorized access. For example, the security unit can monitor the area around the container using surveillance cameras. The surveillance cameras are installed on the outside of the container, record video in real time, and sound an alarm if an anomaly is detected. The security unit can also lock the container door using an electronic lock. The electronic lock controls opening and closing using a PIN code or card key, preventing unauthorized access. Furthermore, the security unit can also detect anomalies inside the container using sensors. The sensors detect anomalies such as temperature, humidity, and vibration, and sound an alarm if an anomaly occurs. Thus, the security unit can protect the contents of the container using any of the following methods: surveillance cameras, electronic locks, or sensors.

[0055] The container installation system may also include a communication unit. The communication unit provides functions for remotely monitoring and controlling the container's status. For example, the communication unit can transmit the container's status to a remote location using a wireless communication device. The wireless communication device is installed inside the container and transmits data such as temperature, humidity, and vibration in real time. The communication unit can also monitor the container's status via the internet. Using an internet connection, the container's status can be checked remotely and controlled as needed. Furthermore, the communication unit can track the container's location using GPS. A GPS device is installed in the container and provides real-time location information. This allows the communication unit to remotely monitor and control the container's status using wireless communication, internet connection, or GPS.

[0056] The container installation system can also be equipped with an energy supply unit. This unit provides power to the equipment and devices inside the container. For example, the energy supply unit can use a solar power generator. The solar power generator is installed on the container's roof and converts sunlight into electricity to power the internal equipment. Alternatively, the energy supply unit can use a wind power generator. The wind power generator is installed around the container and converts wind power into electricity to power the internal equipment. Furthermore, the energy supply unit can store power using batteries. The batteries store the power supplied by the generators and supply it to the internal equipment as needed. Thus, the energy supply unit can power the equipment inside the container using solar power, wind power, or batteries.

[0057] The pile system can also be equipped with a sensor unit. The sensor unit can monitor the soil conditions underground in real time. For example, the sensor unit can measure soil humidity, temperature, and pressure. This allows the system to automatically adjust the expansion and contraction of the reinforcing members in response to changes in the underground environment. For example, if the underground humidity increases, the soil may become softer, potentially reducing the stability of the pile. In this case, the sensor unit can detect the change in humidity and adjust the reinforcing member by extending it to firmly grip the soil. Also, if the underground temperature decreases, the soil may freeze, potentially reducing the stability of the pile. In this case, the sensor unit can detect the change in temperature and adjust the reinforcing member by shortening it to firmly penetrate the soil. Furthermore, the sensor unit can measure the underground pressure and detect anomalies such as earthquakes and ground subsidence. If an anomaly is detected, the sensor unit can issue an alarm to prompt a quick response. As a result, the pile system automatically adjusts in response to changes in the underground environment, ensuring that the container is always installed in the optimal condition.

[0058] The pile system can also be equipped with an energy supply unit. The energy supply unit provides power to electrically control the expansion and contraction of the reinforcing members. For example, the energy supply unit can be equipped with solar panels or wind turbines and can supply power using renewable energy. This allows the pile system to operate using environmentally friendly energy. Solar panels can generate electricity using sunlight during the day and store it in a battery. Wind turbines can generate electricity using wind power and supply the power necessary for the expansion and contraction of the reinforcing members. The energy supply unit can select the optimal energy source according to weather and environmental conditions and supply power efficiently. For example, solar panels can be mainly used on sunny days, and wind turbines can be mainly used on windy days. This ensures that the pile system always receives a stable power supply and can reliably control the expansion and contraction of the reinforcing members.

[0059] The pile system may also be equipped with a communication unit. The communication unit provides communication functions for remotely monitoring and controlling the status of the pile system. For example, the communication unit may be equipped with a wireless communication module and be able to transmit data to a remote administrator via the internet. This allows the administrator to monitor the condition of the soil underground and the expansion and contraction of the reinforcing members in real time. For example, the administrator can use a smartphone or tablet to check the status of the pile system and remotely control the expansion and contraction of the reinforcing members as needed. The communication unit can also issue an alarm and notify the administrator if an abnormality is detected. For example, if an abnormality such as an earthquake or ground subsidence is detected, the communication unit can send an emergency notification to the administrator to prompt a quick response. This enables remote monitoring and control of the pile system, allowing for more efficient and safer operation.

[0060] The pile system can also be equipped with an automated diagnostic unit. The automated diagnostic unit periodically diagnoses the operating status of each part of the pile system and detects any abnormalities. For example, the automated diagnostic unit can monitor the operating status of the expansion / contraction mechanism of the reinforcing member and the sensor part, and issue an alarm if an abnormality is detected. This makes maintenance of the pile system easier and enables early detection and response to failures. For example, if an abnormality occurs in the expansion / contraction mechanism of the reinforcing member, the automated diagnostic unit can identify the location of the abnormality and notify the administrator of the part that needs repair. The automated diagnostic unit can also monitor the operating status of the sensor part and detect sensor failures or malfunctions. This maintains the accuracy of the sensors and provides accurate data. Furthermore, the automated diagnostic unit can record periodic diagnostic results and manage past diagnostic history. This allows for understanding the long-term operational status of the pile system and planning preventive maintenance.

[0061] The pile system can also be equipped with an environmental adaptation unit. The environmental adaptation unit optimizes the operation of the pile system according to the environmental conditions in the ground. For example, the environmental adaptation unit can detect the type of soil, moisture content, temperature, etc., in the ground and adjust the expansion and contraction of the reinforcing members and the driving depth of the piles based on this. This allows the pile system to adapt to various ground conditions and maintain an optimal installation state. For example, in sandy or clayey soils, the expansion and contraction of the reinforcing members can be adjusted to ensure that the piles firmly penetrate the soil. In wetlands and arid areas, the length of the reinforcing members can be adjusted according to the moisture content to ensure the stability of the piles. Furthermore, the environmental adaptation unit can optimize the material and structure of the piles in response to changes in the ground temperature. For example, in cold regions, the pile material can be selected and the expansion and contraction of the reinforcing members adjusted considering the expansion of the soil due to freezing. This allows the pile system to adapt to various environmental conditions and always install containers in an optimal state.
