Description

Method for manufacturing a base 【0001】 The present invention relates to a method for manufacturing a base. 【0002】 Conventionally, as a foundation for buildings and structures, a method of driving piles into the ground and installing a structure thereon has been widely used. By this, the strength of the ground can be reinforced and the stability of the structure can be ensured. In particular, in the case of large structures such as wind turbines, a strong base is required, and a method of driving a plurality of piles is adopted to increase the strength of the ground. 【0003】 Japanese Unexamined Patent Application Publication No. 2018-096076 【0004】 In the conventional technology, a method of driving a plurality of piles is performed to increase the strength of the ground, but there is room for improvement in manufacturing a stronger and more stable base. 【0005】 The method for manufacturing a base according to the embodiment aims to manufacture a strong and stable base. 【0006】 The method for manufacturing a base according to the embodiment includes an excavation step, a first embedding step, a first insertion step, a driving step, a second insertion step, and a second embedding step. The excavation step digs holes at two different depths from the ground. The first embedding step pours a binder so that a predetermined ratio of the holes is filled. The first insertion step inserts a first reinforcing device into the holes into which the binder has been poured. The driving step drives a plurality of piles from the holes into the ground. The second insertion step inserts a second reinforcing device into the first reinforcing device. The second embedding step pours a binder so that the holes are filled. 【0007】 The method for manufacturing a base according to the embodiment can manufacture a strong and stable base. 【0008】Figure 1A is a plan view showing the first process of the foundation manufacturing method according to the embodiment.

Note that the foundation manufacturing method according to the present application is not limited by these embodiments. Furthermore, the same parts will be denoted by the same reference numerals in each of the following embodiments, and redundant explanations will be omitted. 【0010】 The foundation manufacturing method according to this embodiment is a method for manufacturing a strong and stable foundation. This foundation manufacturing method includes an excavation step of digging holes at two different depths from the ground; a first burying step of pouring a binder into the holes so that a predetermined percentage of the holes are filled; a first insertion step of inserting a first reinforcing device into the holes into which the binder has been poured; a driving step of driving a plurality of piles into the ground from the holes; a second insertion step of inserting a second reinforcing device into the first reinforcing device; and a second burying step of pouring a binder into the holes so that the holes are filled. 【0011】 For example, in the excavation process, a convex-shaped hole can be dug, which is like two disc-shaped holes overlapping. In the excavation process, a convex-shaped hole can be dug such that the deeper of the two disc-shaped holes from the ground becomes the convex part. In the first burying process, concrete can be poured in as a binder. In the first insertion process, a stabilizer, which is a device for stabilizing the structure to be installed, can be inserted as the first reinforcing device. In the driving process, multiple piles can be driven around the first reinforcing device, and multiple piles can also be driven in from the top of the first reinforcing device through holes provided in the first reinforcing device. In the second insertion process, a central pillar, which is a device for forming the central axis of the structure to be installed, can be inserted as the second reinforcing device. As a result, the foundation manufacturing method can produce a strong and stable foundation. 【0012】 This disclosure will be described in the following order of items: 1. Embodiments 2. Other Embodiments 【0013】 (1. Embodiments) Figures 1A to 7B are explanatory diagrams for illustrating the base manufacturing method according to the embodiment. The base manufacturing method according to the embodiment will be explained using Figures 1A to 7B. Figures 1A, 2A, 3A, 4A, 5A, 6A, and 7A each show a plan view of each process, and Figures 1B, 2B, 3B, 4B, 5B, 6B, and 7B each show a cross-sectional view of each process. 【0014】 Figures 1A and 1B show the first process of a foundation manufacturing method according to an embodiment. The first process is an excavation process to dig a hole 1. As shown in Figures 1A and 1B, a hole 1 is dug to a certain depth from the ground. The hole 1 is, for example, disc-shaped. The hole 1 is not limited to a disc shape. The entire disc-shaped hole 1 becomes the foundation, and a structure 9 (which may be a building) is installed on top of it. The hole 1 is dug using an appropriate excavation method selected according to the hardness and geology of the ground. The hole 1 is dug perpendicular to the ground using an excavator (such as a hydraulic excavator or drill). 【0015】In the excavation process for drilling hole 1, a disc-shaped hole 1 is drilled at two different depths (h1 and h2) from the ground. Hole 1 includes a first hole 1a at depth h1 and a second hole 1b at depth h2. The first hole 1a is located in the center of the entire hole 1 and is the deepest from the ground. The second hole 1b is located around the first hole 1a and is shallower than the first hole 1a. 【0016】 The excavation process to dig hole 1 creates a first disc-shaped hole 1a with a depth h1 and a second disc-shaped hole 1b with a depth h2, resulting in a convex disc-shaped hole 1 where the two disc-shaped holes 1a and 1b overlap. A convex disc-shaped hole 1 is created where the first hole 1a becomes the convex part. 【0017】 A device called a stabilizer 2 (corresponding to the first reinforcing device) for stabilizing the structure 9 is inserted into the first hole 1a at a depth h1 (described later in the third process). The depth h1 may be adjusted to allow the stabilizer 2 to be inserted to an appropriate degree. The depth h1 may be determined according to the height of the stabilizer 2 and the size (weight, height, width, etc.) of the structure 9 installed on top. 【0018】 The diameter d1 of the first hole 1a with a depth h1 may be adjusted to a size that allows the stabilizer 2 to be inserted to an appropriate degree. The diameter d1 may be determined according to the diameter of the stabilizer 2, the size of the structure 9 installed on top, etc. 【0019】 The diameter d2 of the second hole 1b, which has a depth of h2, is at least greater than the diameter d1. The diameter d2 may be determined according to the size of the structure 9 to be installed on top. 【0020】 Furthermore, a slope-shaped hole 3 is dug along with the disc-shaped hole 1 (corresponding to the diagonal lines in the diagram). The slope-shaped hole 3 is a hole through which vehicles transporting equipment and other materials can pass. The slope-shaped hole 3 is a hole through which vehicles can pass so that equipment and other materials can be transported to the disc-shaped hole 1. The slope-shaped hole 3 is dug so as to be directly connected to the disc-shaped hole 1. The vehicles may be transport vehicles such as trucks that transport the excavated soil and equipment, and the excavated soil and equipment may be transported out of the site through the slope-shaped hole 3 and processed at an appropriate disposal site. 【0021】 The slope-shaped hole 3 is deepest from the ground at one end, which is directly connected to the second hole 1b, reaching a depth of approximately h2. The depth of the slope-shaped hole 3 may be determined according to the depth of the second hole 1b. The other end of the slope-shaped hole 3 is dug so as to be directly connected to the ground. The other end of the slope-shaped hole 3 is shallowest from the ground and gradually becomes deeper towards the end that is directly connected to the disc-shaped hole 1. 【0022】 Figures 2A and 2B show the second process of the foundation manufacturing method according to the embodiment. The second process is an embedding process (first embedding process) in which concrete 4 is poured. Similar to Figures 1A and 1B, the diagonal lines in the figures indicate slope-shaped holes 3. As shown in Figures 2A and 2B, concrete 4 (an example of a binder) is poured into the disc-shaped holes 1 dug in the first process. 【0023】 In the embedding process where concrete 4 is poured, concrete 4 is poured so that a predetermined proportion of the entire disc-shaped hole 1 is filled. For example, concrete 4 is poured so that about one-quarter of the entire disc-shaped hole 1 is filled. The concrete 4 is poured so that it is evenly distributed in all directions of the disc-shaped hole 1. The concrete 4 is poured to the extent that the first hole 1a at a depth of h1 is no longer visible. The concrete 4 is poured to the extent that it minimally covers the entire second hole 1b at a depth of h2. The concrete 4 is poured so as not to erode the slope-shaped hole 3. A frame is installed at the connection between the slope-shaped hole 3 and the disc-shaped hole 1 to prevent concrete 4 from flowing into the slope-shaped hole 3. The poured concrete 4 corresponds to the dot pattern in the figure. 【0024】Figures 3A and 3B show the third process of the foundation manufacturing method according to the embodiment. The third process is the step of inserting the stabilizer 2 (first insertion step). Similar to Figures 1A and 1B, the diagonal lines in the figures indicate slope-shaped holes 3, and similar to Figures 2A and 2B, the dotted patterns in the figures indicate poured concrete 4. As shown in Figures 3A and 3B, the stabilizer 2 (corresponding to the vertical lines in the figures) is inserted before the concrete 4 poured in the second process dries. The stabilizer 2 is a device for stabilizing the structure 9, and by inserting the stabilizer 2, the durability of the structure 9 is increased, resulting in a more robust structure 9. 【0025】 In the process of inserting the stabilizer 2, the stabilizer 2 is lifted to a sufficient height using the crane 5 and inserted perpendicularly into the first hole 1a as shown in Figures 3A and 3B. The stabilizer 2 is inserted into the first hole 1a, which is filled to a depth h1 of concrete 4. The stabilizer 2 is slowly inserted from one end using the crane 5. Throughout the insertion process, the stabilizer 2 is slowly inserted while always maintaining a perpendicular orientation to the hole. 【0026】 The stabilizer 2 has a cylindrical portion 2a and a disc portion 2b, and is inserted from the cylindrical portion 2a. More precisely, it is the cylindrical portion 2a of the stabilizer 2 that is inserted into the concrete 4. More precisely, the depth h1 may be adjusted to a depth that allows the cylindrical portion 2a of the stabilizer 2 to be inserted to an appropriate degree. More precisely, the diameter d1 may be adjusted to a size that allows the cylindrical portion 2a of the stabilizer 2 to be inserted to an appropriate degree. 【0027】 Figures 4A and 4B show the state after the third process of the foundation manufacturing method according to the embodiment. Similar to Figures 1A and 1B, the diagonal lines in the figures indicate slope-shaped holes 3, similar to Figures 2A and 2B, the dotted patterns in the figures indicate poured concrete 4, and similar to Figures 3A and 3B, the vertical lines in the figures indicate stabilizers 2. Figures 4A and 4B show the state in which the stabilizer 2 is inserted into the first hole 1a with a depth of h1 by the third process of the foundation manufacturing method according to the embodiment. 【0028】 Figures 5A and 5B show the fourth process of the foundation manufacturing method according to the embodiment. The fourth process is a driving process in which piles 6 are driven into the ground. Similar to Figures 1A and 1B, the diagonal lines in the figures indicate slope-shaped holes 3, similar to Figures 2A and 2B, the dotted patterns in the figures indicate poured concrete 4, and similar to Figures 3A and 3B, the vertical lines in the figures indicate stabilizers 2. As shown in Figures 5A and 5B, before the concrete 4 poured in the second process has completely dried, piles 6 (corresponding to stakes) are driven into the ground around and on top of the stabilizers 2 inserted in the third process. 【0029】 In the pile driving process, multiple (or many) piles 6 are driven around and above the stabilizer 2. The piles 6 driven into the top of the stabilizer 2 penetrate the stabilizer 2. More precisely, holes are provided in the stabilizer 2 (more precisely, the disc portion 2b of the stabilizer 2) for the piles 6 to pass through, and the piles are driven in through these holes. The piles 6 that penetrate the stabilizer 2 may also be driven into the concrete 4 below the disc portion 2b of the stabilizer 2. 【0030】 The piles 6 driven around the stabilizer 2 are driven into the concrete 4 in all directions (concrete 4 portion) of the second hole 1b at a depth of h2. For example, they are driven so that they are uniformly distributed in all directions of the second hole 1b at a depth of h2. For example, they are driven so that they are uniformly distributed at predetermined intervals. For example, they are driven so that they are uniformly distributed at predetermined intervals in a disc shape depending on the shape of the first hole 1a at a depth of h1 or the second hole 1b at a depth of h2. The piles 6 driven around the stabilizer 2 are driven into the concrete 4 that has spread in all directions of the second hole 1b at a depth of h2. 【0031】 The pile 6 is driven perpendicularly into a second hole 1b dug to a certain depth from the ground. The pile 6 driven into the upper part of the stabilizer 2 is driven perpendicularly through a hole provided in the stabilizer 2. The pile 6 may be connected to other piles 6, etc., with connecting members. 【0032】Figures 6A and 6B show the fifth process of the foundation manufacturing method according to the embodiment. The fifth process is the insertion process of the central pillar 7 (second insertion process). Similar to Figures 1A and 1B, the diagonal lines in the figures indicate slope-shaped holes 3, similar to Figures 2A and 2B, the dotted lines in the figures indicate poured concrete 4, and similar to Figures 3A and 3B, the vertical lines in the figures indicate stabilizers 2. As shown in Figures 6A and 6B, the central pillar 7 (corresponding to the second reinforcing device: corresponding to the horizontal lines in the figures) is inserted into the cylindrical portion 2a of the stabilizer 2 inserted in the third process. The central pillar 7 is, for example, a device for constructing the most durable foundation 8 when manufacturing the foundation 8 according to the embodiment, and the central axis of the structure 9 may be formed on the upper part of the central pillar 7. 【0033】 In the insertion process of the central pillar 7, similar to the insertion of the stabilizer 2, the central pillar 7 is lifted to a sufficient height using the crane 5 and inserted perpendicularly to the cylindrical portion 2a of the stabilizer 2. The central pillar 7 is slowly inserted from one end using the crane 5, so that the other end of the central pillar 7 protrudes to an appropriate extent from the cylindrical portion 2a of the stabilizer 2. Throughout the insertion process, the central pillar 7 is slowly inserted while always maintaining a perpendicular orientation to the cylindrical portion 2a of the stabilizer 2. 【0034】 During the insertion process of the central pillar 7, a portion of the central pillar 7 protrudes from the disc portion 2b of the stabilizer 2. The height of the central pillar 7 may be adjusted so that it protrudes from the stabilizer 2 to an appropriate extent when inserted into the stabilizer 2. The diameter of the central pillar 7 may be adjusted to be small enough to be inserted into the stabilizer 2. 【0035】Figures 7A and 7B show the sixth process of the foundation manufacturing method according to the embodiment. The sixth process is the burying process (second burying process) in which concrete 4 is poured. Similar to Figures 1A and 1B, the diagonal lines in the figures indicate slope-shaped holes 3, similar to Figures 2A and 2B, the dotted patterns in the figures indicate poured concrete 4, and similar to Figures 3A and 3B, the vertical lines in the figures indicate stabilizers 2. 【0036】 After the insertion of the central pillar 7 in the fifth process, concrete 4 is poured so that it is evenly distributed in all directions of the disc-shaped hole 1, similar to the first process. Unlike the first process, concrete 4 is poured so that the entire disc-shaped hole 1 is completely filled. Concrete 4 is poured so that the entire first hole 1a at depth h1 and the second hole 1b at depth h2 are completely filled. Concrete 4 is also poured so that the inside of the central pillar 7 is completely filled. Enough concrete 4 is poured so that the entire disc-shaped hole 1 is completely filled. Enough concrete 4 is poured so that the entire disc-shaped hole 1 is completely filled, including the inside of the central pillar 7. 【0037】 The burying process in the sixth process completely obscures the stabilizer 2 inserted in the third process, and also completely obscures the pile 6 driven in during the fifth process. 【0038】 In the first process, during the burying step, the frame installed at the connection point between the slope-shaped hole 3 and the disc-shaped hole 1 is removed, and the slope-shaped hole 3 is completely filled with soil 4a (corresponding to the black-painted pattern in the figure). The slope-shaped hole 3 may also be filled with concrete 4, and concrete 4 may be poured in until the slope-shaped hole 3 is completely hidden. 【0039】 Figures 7A and 7B show the state in which the entire disc-shaped hole 1 is filled with concrete 4 by the sixth process of the base manufacturing method according to the embodiment. The figures show the state in which concrete 4 is poured into the entire disc-shaped hole 1 and the entire disc-shaped hole 1 is completely closed. 【0040】 In the sixth process, the burying step completely fills the entire disc-shaped hole 1, leaving a portion of the central pillar 7 protruding from the ground. Concrete 4 is poured to completely fill the inside of the central pillar 7, so the protruding portion is also covered with concrete 4. The central axis of the structure 9 is formed on the upper part of the protruding portion of the central pillar 4. 【0041】 The above describes the processes of the foundation manufacturing method according to the embodiment. Through these processes, the foundation 8 manufactured according to the foundation manufacturing method according to the embodiment is produced. The following describes how to connect the foundation 8 manufactured according to the foundation manufacturing method according to the embodiment to the structure 9. The following description will use the case where the structure 9 is a wind turbine 9 and the foundation 8 manufactured according to the foundation manufacturing method according to the embodiment is connected to the wind turbine 9 as an example, but the structure 9 is not limited to a wind turbine 9. 【0042】 After the burial process of the fifth process, the base 8 manufactured in the fifth process and the wind turbine 9 to be installed on top of the base 8 are connected. 【0043】 For example, in the process of connecting the base 8 and the wind turbine 9, multiple bolts and nuts (bolts, etc. 10) are used (multiple bolts are inserted into nuts that act as donut-shaped plates) to connect the base 8 manufactured in the fifth process with the wind turbine 9 to be installed on top of the base 8. Multiple bolts, etc. 10 are used along the wind turbine 9 to connect the base 8 and the wind turbine 9. The bolts, etc. 10 are tightened with appropriate torque so that the base 8 and the wind turbine 9 are firmly fixed together. The connection between the base 8 and the wind turbine 9 may be made by bolting or by welding. 【0044】FIG. 8 is a diagram showing a connection method using the base 8 manufactured by the base manufacturing method according to the embodiment. FIG. 8 shows a state in which the windmill 9, which is a structure 9 to be installed, is connected to the base 8 manufactured by the base manufacturing method according to the embodiment. The windmill 9 and the other end side of the central pillar 7 are connected using a plurality of bolts or the like 10, and the windmill 9 and the concrete 4 are connected using a plurality of bolts or the like 10. The central pillar 7 is at the center of the base 8, and the other end side of the central pillar 7 appears to protrude from the ground, so that the windmill 9 and the base 8 can be firmly fixed using the bolts or the like 10 while accurately confirming the position. 【0045】 A variation of the base manufacturing method according to the embodiment will be described. In the above embodiment, a method of manufacturing the base 8 by inserting the stabilizer 2 in the third process and inserting the central pillar 7 in the fifth process has been described. In the above embodiment, a method of manufacturing the base 8 by separately inserting the stabilizer 2 and the central pillar 7 in different processes has been described. However, in the process of inserting the stabilizer 2 in the third process, the central pillar 7 may be inserted simultaneously. For example, in the third process, a device in which the stabilizer 2 and the central pillar 7 are integrated may be inserted. 【0046】 In this variation, in the insertion process of the third process, the crane 5 is used to lift the device in which the stabilizer 2 and the central pillar 7 are integrated to a sufficient height, and the device in which the stabilizer 2 and the central pillar 7 are integrated is inserted in the vertical direction with respect to the first hole 1a, similar to the case shown in FIGS. 3A and 3B. The device in which the stabilizer 2 and the central pillar 7 are integrated is inserted into the first hole 1a having a depth h1 into which the concrete 4 is poured. The device in which the stabilizer 2 and the central pillar 7 are integrated is slowly inserted from one end side using the crane 5. During the insertion, the device in which the stabilizer 2 and the central pillar 7 are integrated is slowly inserted while always maintaining the vertical direction with respect to the first hole 1a. 【0047】The device in which the stabilizer 2 and the central pillar 7 are integrated has a cylindrical portion 2a of the stabilizer 2 into which the central pillar 7 is inserted, a disk portion 2b of the stabilizer 2, and a portion of the central pillar 7 protruding from the stabilizer 2. 【0048】 In the driving step of the fourth process, a plurality of piles 6 are driven around and above the disk portion (corresponding to the disk portion 2b of the stabilizer 2) of the device in which the stabilizer 2 and the central pillar 7 are integrated. A hole for passing the pile 6 is provided in the disk portion of the device in which the stabilizer 2 and the central pillar 7 are integrated, and the pile is driven through this hole. 【0049】 In this variation, the insertion step of the fifth process is omitted, and in the embedding step of the sixth process, concrete 4 is poured so that the entire disk-shaped hole 1 is completely filled, as in the case shown in FIGS. 7A and 7B. Thereby, a base 8 similar to that of the above embodiment is manufactured. That is, a strong and stable base 8 can be manufactured. 【0050】 (2. Other embodiments) Hereinafter, other forms for implementing the base manufacturing method according to the present application will be described in detail. Note that the base manufacturing method according to the present application is not limited by this embodiment. 【0051】The foundation manufacturing method according to this embodiment is a method for manufacturing a strong and stable foundation. This foundation manufacturing method includes an excavation step of digging a hole to a certain depth from the ground; a driving step of driving one end of a plurality of piles into the ground from the hole and driving one end of a steel column into the ground; a connecting step of connecting the other ends of the plurality of piles and the other end of the steel column with a connecting member; an burying step of pouring a binder into the hole to fill the hole; and a fixing step of fixing the other end of the steel column to the binder. For example, in the excavation step, a disc-shaped hole can be dug. In the driving step, a steel column can be driven into the center of a plurality of piles. In the connecting step, the other ends of the plurality of piles can be connected to the connecting member and the other end of the steel column can be connected to the connecting member. In the burying step, concrete can be poured as a binder. In the fixing step, the other end of the steel column protruding from the binder can be fixed to the binder. The depth to which a hole is dug from the ground is, for example, about 100 mm. This allows the foundation manufacturing method to produce a strong and stable foundation. 【0052】The foundation manufacturing method according to this embodiment comprises an excavation step, a driving step, a connecting step, an burying step, and a fixing step. The excavation step involves digging a hole to a certain depth from the ground. The excavation step involves, for example, digging a hole perpendicular to the ground using an excavator. The excavation step can also involve selecting an appropriate excavation method according to the hardness and geological conditions of the ground. Furthermore, the excavation step can be set to, for example, an excavation depth of about 100 mm. The driving step involves driving one end of a plurality of piles into the ground from the hole, and driving one end of a steel column into the ground. The driving step involves, for example, driving the piles into the ground using a pile driver. Furthermore, the driving step can also involve, for example, positioning the steel column between the piles and driving them in simultaneously. Furthermore, the driving step can be performed while precisely adjusting the positions of the piles and steel columns. The connecting step involves connecting the other ends of the plurality of piles and the other ends of the steel columns with connecting members. The connecting step involves fixing the piles and steel columns using connecting members. Furthermore, the connection process allows for the selection of the material and shape of the connecting members, for example. Additionally, the connection process allows for the fixing of the connecting members with bolts and nuts. The burying process involves pouring a binder into the hole to fill it. The burying process allows for the filling of the hole using concrete, for example. The burying process also allows for the adjustment of the amount of binder poured, for example. Furthermore, care can be taken to ensure that the binder is evenly distributed during the burying process. The fixing process involves fixing the other end of the steel column to the binder. The fixing process supports the steel column, for example, until the binder hardens. The fixing process can also fix the steel column after the binder has completely hardened. Furthermore, the fixing process can utilize reinforcing materials for fixing, for example. Thus, the foundation manufacturing method according to this embodiment can produce a strong and stable foundation. 【0053】The excavation process involves digging a hole to a certain depth from the ground. For example, the excavation process involves using an excavator to dig a hole perpendicular to the ground. Specifically, excavators include hydraulic shovels and drills, and these machines are selected according to the hardness and geological conditions of the ground. The excavator is installed perpendicular to the ground, and an operator controls the machine to dig the hole. The excavation depth is set according to the design drawings, usually around 100 mm, but can be adjusted as needed. In the excavation process, an appropriate excavation method can be selected depending on the hardness and geological conditions of the ground. For example, in hard ground, a drill is used for excavation, while in soft ground, a hydraulic shovel is used. Furthermore, in the excavation process, the angle of the excavator's cutting edge and the rotation speed can be adjusted to ensure efficient excavation. After excavation is complete, a leveling operation is performed using specialized tools to flatten the bottom of the excavated hole. This prepares the area for the accurate installation of piles or steel columns in the subsequent driving process. Furthermore, during the excavation process, the transportation and disposal methods for the excavated soil are also considered in order to properly handle it. The excavated soil is transported off-site using transport vehicles such as trucks and processed at an appropriate disposal site. This ensures cleanliness and safety at the excavation site. 【0054】The driving process involves driving one end of multiple piles into the ground through holes, as well as driving one end of a steel column. The driving process involves, for example, using a pile driver to drive the piles into the ground. Specifically, hydraulic or pneumatic pile drivers are used; these machines possess powerful impact force, allowing the piles to be driven deep into the ground. In the driving process, it is crucial to precisely adjust the position of the piles during driving. The pile positions are precisely set based on design drawings, and their positions are confirmed using laser measuring instruments or GPS. After the piles are positioned correctly, a pile driver is used to drive them into the ground. During driving, care is taken to ensure the piles are driven vertically, and their positions are fine-tuned as needed. Similarly, steel columns are placed between the piles and driven into the ground using a pile driver. The position of the steel columns is also precisely adjusted, so that the piles and steel columns work together to form a strong foundation. The driving process allows for precise adjustment of the positions of the piles and steel columns during driving. This ensures the strength and stability of the foundation. Furthermore, during the driving process, the driving depth and impact force are adjusted to ensure appropriate driving according to the hardness and geological conditions of the ground. After the driving is complete, the positions of the piles and steel columns are checked again, and fine adjustments are made as needed. This prepares the structure for accurately connecting the piles and steel columns in the next connection process. 【0055】The connection process involves connecting the other ends of multiple piles to the other ends of steel columns using connecting members. For example, the connection process involves fixing the piles and steel columns using connecting members. Specifically, metal plates or brackets are used as connecting members, and these members are designed to firmly fix the piles and steel columns. The connecting members are selected based on the design drawings, and their material and shape are determined considering the strength and durability of the foundation. The connecting members are attached to the other ends of the piles and steel columns and secured using bolts and nuts. The bolts and nuts are tightened to the appropriate torque to ensure that the connecting members are securely fixed. During the connection process, the mounting position and angle of the connecting members are precisely adjusted so that the piles and steel columns form a strong, integrated foundation. After the installation of the connecting members is complete, the fixing status of the connecting members is checked, and tightening is performed again if necessary. This ensures that the connecting members are securely fixed, and the strength and stability of the foundation are ensured. Furthermore, the material and shape of the connecting members can be selected during the connection process. For example, highly corrosion-resistant stainless steel or high-strength alloy steel may be used as connecting members. This improves the durability of the foundation and allows it to maintain a stable state over a long period of time. 【0056】 The burying process involves pouring a binder into the hole to fill it. For example, the burying process involves filling the hole with concrete. Specifically, a concrete mixer is used to mix the binder to create concrete with the appropriate viscosity and strength. The concrete is then poured into the hole using a concrete pump truck, with care taken to ensure even distribution. The amount of binder poured can be adjusted during the burying process. Vibrators and tapping tools are used to evenly distribute the concrete to ensure the binder is evenly distributed. This ensures that the binder fills the gaps without creating any gaps, forming a strong foundation. The burying process allows for careful attention to ensure even distribution of the binder. Even distribution of the binder improves the strength and stability of the foundation, allowing it to maintain a stable state over a long period. Furthermore, the burying process takes into account the hardening time of the binder. Proper curing is carried out until the binder is completely hardened to ensure even hardening. This maximizes the strength of the binder and improves the durability of the foundation. 【0057】 The fixing process involves securing the other end of the steel column to the connector. The fixing process supports the steel column, for example, until the connector hardens. Specifically, supports are used with posts and clamps to ensure the steel column is securely fixed to the connector. The posts and clamps are adjusted to ensure the steel column stands vertically and stabilize it until the connector hardens. The fixing process allows the steel column to be fixed after the connector has fully hardened. After the connector has hardened, the posts and clamps are removed to confirm that the steel column is securely fixed to the connector. Reinforcement materials can be used for fixing if necessary. Metal plates and brackets are used as reinforcement, and these components further strengthen the connection between the steel column and the connector. The fixing process involves precisely adjusting the mounting position and angle of the reinforcement materials to ensure the steel column is securely fixed to the connector. After the reinforcement materials are installed, their fixation is checked and tightened again if necessary. This ensures the steel column is securely fixed and the strength and stability of the base are ensured. Furthermore, reinforcing materials can be used during the fixing process. These reinforcing materials may include highly corrosion-resistant stainless steel or high-strength alloy steel. This improves the durability of the foundation, allowing it to maintain a stable state over a long period. 【0058】 The excavation process can dig a disc-shaped hole. The excavation process, for example, uses a disc-shaped excavator to dig the hole. Furthermore, the excavation process, for example, can improve the stability of the foundation by digging a disc-shaped hole. In addition, the excavation process, for example, can ensure that the binder is evenly distributed by digging a disc-shaped hole. This improves the stability of the foundation by digging a disc-shaped hole. 【0059】The driving process allows for the steel column to be driven into the center of multiple piles. For example, the driving process can precisely adjust the arrangement of the piles and drive the steel column into the center. Furthermore, the driving process can be performed while precisely adjusting the positions of the piles and the steel column. Moreover, by precisely adjusting the positions of the piles and the steel column during the driving process, the strength of the foundation can be improved. Thus, driving the steel column into the center of multiple piles improves the strength of the foundation. 【0060】 The connection process can connect the other ends of multiple piles to the connecting members, and also connect the other end of a steel column to the connecting members. The connection process can, for example, fix the piles and steel columns using the connecting members. Furthermore, the connection process can, for example, select the material and shape of the connecting members. In addition, the connection process can, for example, fix the connecting members with bolts and nuts. As a result, the integrity of the foundation is improved by connecting multiple piles and steel columns with connecting members. 【0061】 The burying process can involve pouring concrete as a binder. For example, the burying process can involve filling the hole with concrete. Furthermore, the burying process can involve adjusting the amount of binder poured. Additionally, care can be taken to ensure the binder is evenly distributed. This improves the strength of the foundation by using concrete as a binder. 【0062】 The fixing process can secure the other end of the steel column protruding from the connecting member to the connecting member. The fixing process supports the steel column, for example, until the connecting material hardens. Alternatively, the fixing process can secure the steel column after the connecting material has completely hardened. Furthermore, the fixing process can utilize reinforcing materials for fixing. This improves the stability of the base by securing the connecting member and the steel column. 【0063】 The system according to the embodiment is not limited to the example described above, and various modifications are possible, for example, as follows. 【0064】The foundation manufacturing system also includes a vibration analysis unit.

The unit can control cooling and heating devices to keep the binder temperature within an appropriate range. Furthermore, the unit can adjust the curing time according to the temperature changes of the binder, providing optimal curing conditions.

The vibration process is performed after the burying process and involves applying vibration to ensure that the binder is evenly distributed. For example, by using a vibrator to vibrate the binder, the density of the binder can be increased and air can be removed. This improves the strength of the binder and further enhances the stability of the foundation. The vibration process must be performed before the binder hardens, and it is important to apply vibration at the appropriate time. The type of vibrator and the intensity of the vibration are selected according to the type and amount of binder. By performing the vibration process, air remaining inside the binder is expelled, and the binder is evenly distributed. This improves the strength and durability of the foundation and allows it to maintain a stable state over a long period of time. Furthermore, the vibration process also has the effect of shortening the hardening time of the binder, contributing to a shorter construction period. 【0070】 The foundation manufacturing method may include a temperature control process in addition to the excavation, driving, joining, burying, and fixing processes. The temperature control process is a process to maintain an appropriate temperature during the curing process of the binder. For example, if the ambient temperature is low when the binder is curing, a heater can be used to raise the temperature of the binder. Conversely, if the ambient temperature is high, a cooling device can be used to lower the temperature of the binder. By performing the temperature control process, the curing of the binder proceeds uniformly, and its strength is improved. The temperature control process involves setting an appropriate temperature according to the type of binder and the construction environment, and monitoring the temperature using a temperature sensor. By performing the temperature control process, curing defects of the binder can be prevented, and the strength and durability of the foundation can be ensured. Furthermore, the temperature control process also has the effect of optimizing the curing time of the binder, contributing to a reduction in the construction period. 【0071】The foundation manufacturing method may include a humidity control process in addition to the excavation, driving, joining, burying, and fixing processes. The humidity control process is a process to maintain appropriate humidity during the curing process of the binder. For example, if the external humidity is low when the binder is curing, a humidifier can be used to increase the humidity around the binder. Conversely, if the humidity is high, a dehumidifier can be used to decrease the humidity around the binder. By implementing the humidity control process, the curing of the binder proceeds uniformly, and its strength is improved. The humidity control process involves setting an appropriate humidity according to the type of binder and the construction environment, and monitoring the humidity using a humidity sensor. By implementing the humidity control process, curing defects of the binder can be prevented, and the strength and durability of the foundation can be ensured. Furthermore, the humidity control process also has the effect of optimizing the curing time of the binder, contributing to a reduction in the construction period. 【0072】 The foundation manufacturing method may include a pressure management process in addition to the excavation, driving, connecting, burying, and fixing processes. The pressure management process is a process to maintain appropriate pressure during the hardening process of the binder. For example, if there is insufficient external pressure when the binder hardens, a pressurizing device can be used to apply pressure to the binder. Conversely, if the pressure is excessive, a depressurizing device can be used to reduce the pressure on the binder. By performing the pressure management process, the hardening of the binder proceeds uniformly, and its strength is improved. The pressure management process involves setting an appropriate pressure according to the type of binder and the construction environment, and monitoring the pressure using a pressure sensor. By performing the pressure management process, hardening defects of the binder can be prevented, and the strength and durability of the foundation can be ensured. Furthermore, the pressure management process also has the effect of optimizing the hardening time of the binder, contributing to a reduction in the construction period. 【0073】The foundation manufacturing method may include a surface finishing process in addition to the excavation, driving, joining, burying, and fixing processes. The surface finishing process is performed to smooth the surface of the foundation after the binder has hardened. For example, after the binder has hardened, the surface of the foundation can be polished using a grinding machine to achieve a smooth finish. Performing the surface finishing process makes the surface of the foundation uniform, facilitating the installation of the superstructure. The surface finishing process is carried out while checking the hardening state of the binder, and an appropriate grinding method is selected. The type of grinding machine and the grit size of the abrasive are selected according to the material of the foundation and the required finish. Performing the surface finishing process makes the surface of the foundation smooth, stabilizes the installation of the superstructure, and improves the overall construction quality.
