Specific Embodiments

[0038] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments of the present invention fall within the scope of protection of the present invention.

[0039] Embodiment:

[0040] As Figures 1-8 shown, the civil engineering foundation connection structure for a substation project provided in this embodiment includes a base 100, an installation pipe 200, an installation frame 300, and a ground plug 400 with a tip, wherein:

[0041] The base 100 is provided with a casting cavity 110 inside. The casting cavity 110 penetrates through the bottom end of the base 100. A through hole communicating with the casting cavity 110 is formed on the top surface of the base 100. The installation pipe 200 is inserted through the through hole and integrally formed with or welded to the base 100. The installation pipe 200 communicates with the casting cavity 110. In this way, part of the concrete entering the installation pipe 200 will flow into the above-mentioned casting cavity 110. The upper part of the installation pipe 200 is located above the base 100. The section of the installation pipe 200 located above the base 100 forms an embedded section. Optionally, the above-mentioned installation pipe 200 is a vertically arranged square pipe, and the above-mentioned through hole is a square hole adapted to the square pipe;

[0042] The mounting bracket 300 is provided with a connecting part 310 for mounting electrical equipment. For example, the connecting part 310 is a wire rack capable of passing through wires. The bottom end of the mounting bracket 300 is integrally formed with or welded to a base 320. A groove is formed at the bottom end of the base 320. The shape and size of the groove are adapted to the outer contour of the above-mentioned embedded section. A fixing block 330 is fixedly provided in the groove. The shape and size of the fixing block 330 are adapted to the inner hole of the above-mentioned embedded section. The mounting bracket 300 is provided with a main casting hole 340 penetrating through the bottom end of the fixing block 330, that is, the above-mentioned main casting hole 340 penetrates through the above-mentioned mounting bracket 300 and the above-mentioned fixing block 330. It can also be understood that the mounting bracket 300 and the fixing block 330 are respectively provided with a first casting hole and a second casting hole, and the first casting hole and the second casting hole communicate to form the above-mentioned main casting hole 340.

[0043] The ground plug 400 is slidably installed in the installation pipe 200. A gap for the concrete to pass through is formed between the ground plug 400 and the pipe wall of the installation pipe 200, that is, the ground plug 400 cannot completely block the above-mentioned installation pipe 200. The tip of the ground plug 400 faces downward.

[0044] During assembly, the embedded section is inserted into the groove, so that the fixing block 330 is inserted into the embedded section. And when the fixing block 330 is inserted into the embedded section, the fixing block 330 pushes the ground plug 400 downward, causing the tip of the ground plug 400 to extend out of the installation pipe 200 and the base 100.

[0045] With the above-mentioned connecting part 310, this connecting structure can install power equipment. When installing this connecting structure, first place the base 100 on the civil engineering foundation, and then insert the above-mentioned embedded section into the groove so that the embedded section is docked with the base 320. At this time, the fixing block 330 will synchronously insert into the inner hole of the embedded section, thereby pushing down the ground plug 400 so that the tip of the ground plug 400 extends out of the installation pipe 200 and the base 100. The tip of the ground plug 400 extending out of the base 100 will be inserted into the civil engineering foundation. Subsequently, pour concrete into the main pouring hole 340. Since the fixing block 330 is placed in the installation pipe 200, the concrete entering the main pouring hole 340 will flow into the installation pipe 200. Since the installation pipe 200 is connected to the pouring cavity 110 of the above-mentioned base 100, the concrete entering the installation pipe 200 will flow into the pouring cavity 110. Since the pouring cavity 110 penetrates the bottom surface of the base 100, the concrete entering the pouring cavity 110 will be directly stacked on the civil engineering foundation. After the concrete solidifies, the base 100 will be connected to the civil engineering foundation. Together with the ground plug 400 inserted into the civil engineering foundation, the base 100 will be firmly connected to the ground of the civil engineering foundation. Of course, the main pouring hole 340 and the installation pipe 200 will also be filled with concrete. After this part of the concrete solidifies, the installation frame 300 will be firmly connected to the base 100.

[0046] Through the above structure, the civil engineering foundation connecting structure provided by the present invention only needs to adopt a plugging method to dock the installation frame 300 and the base 100 and make the ground plug 400 insert into the ground of the civil engineering foundation. Moreover, this connecting structure makes the installation frame 300 and the base 100 fixedly connected by pouring concrete and makes the base 100 fixedly connected to the ground of the civil engineering foundation. In this way, this civil engineering foundation connecting structure does not need to use bolts during assembly and installation, the assembly and installation are simple and convenient, and after installation, it can be stably placed on the civil engineering foundation. With the installation part of the installation frame 300, it is convenient to install power equipment on it.

[0047] An optional implementation manner of this embodiment is as follows: An air-filled balloon 500 is installed in the above-mentioned embedded section. The air-filled balloon 500 is located above the above-mentioned ground plug 400. When the fixing block 330 inserts into the embedded section, the fixing block 330 squeezes the air-filled balloon 500 to make the air-filled balloon 500 expand downward, and the downward-expanded air-filled balloon 500 pushes the ground plug 400 to move downward. In this way, when the fixing block 330 just enters the embedded section, it will squeeze the above-mentioned air-filled balloon 500 to make the air-filled balloon 500 start to expand downward and squeeze the ground plug 400 downward. Therefore, with the help of the above-mentioned air-filled balloon 500, the ground plug 400 can move downward when the fixing block 330 just enters the embedded section. When the fixing block 330 is completely inserted into the embedded section, the air-filled balloon 500 is squeezed and broken by the fixing block 330.

[0048] An alternative implementation of this embodiment is as follows: The above-mentioned ground plug 400 includes a connecting column 410 and a plug rod 413, where:

[0049] The plug rod 413 is fixedly connected to the bottom end of the connecting column 410. The tip of the ground plug 400 is located at one end of the plug rod 413 away from the connecting column 410. A slider 414 is connected to the top end of the above-mentioned connecting column 410. A guide rail 600 is fixedly provided on the inner wall of the middle part of the above-mentioned installation pipe 200. The above-mentioned slider 414 is slidably installed on the above-mentioned guide rail 600 up and down. The above-mentioned air-filled balloon 500 is located above the slider 414. When the fixing block 330 is inserted into the above-mentioned embedding section, the above-mentioned air-filled balloon 500 is in contact with the top end of the slider 414. When the air-filled balloon 500 is squeezed by the fixing block 330 and expands and deforms downward, the downward-expanded air-filled balloon 500 pushes the above-mentioned slider 414 downward, so that the connecting column 410 and the plug rod 413 move downward synchronously.

[0050] Optionally, the number of the above-mentioned ground plugs 400 is multiple. The multiple ground plugs 400 are evenly divided into two groups. The connecting columns 410 of each group of ground plugs 400 are connected to the same slider 414. The number of the above-mentioned guide rails 600 is two. The two guide rails 600 are symmetrically distributed on the inner wall of the middle part of the installation pipe 200. Two sliders 414 are respectively slidably installed on the two above-mentioned guide rails 600. And the number of the above-mentioned air-filled balloons 500 is also two. The two air-filled balloons 500 are respectively located above the two sliders 414. That is, the two air-filled balloons 500 are respectively used to push the two sliders 414. A gap for the concrete to pass through is provided between the two above-mentioned air-filled balloons 500 and between the two above-mentioned sliders 414. In this way, the concrete can smoothly enter the lower part of the installation pipe 200. When multiple ground plugs 400 are inserted into the ground of the civil engineering foundation, the connection force generated is greater.

[0051] More preferably, the above-mentioned connecting column 410 includes a push rod 411 and a diameter-expanded rod 412 with an outer diameter larger than that of the push rod 411. The diameter-expanded rod 412 is fixedly provided between the push rod 411 and the plug rod 413. Both the push rod 411 and the diameter-expanded rod 412 are straight rods, and the push rod 411 and the diameter-expanded rod 412 are coaxially arranged. At this time, the above-mentioned push rod 411 is located above the diameter-expanded rod 412, and the diameter-expanded rod 412 is located above the plug rod 413. A receiving groove 4121 is formed on the top surface of the above-mentioned diameter-expanded rod 412. Because the concrete can smoothly enter the middle and lower parts of the installation pipe 200, the section of the installation pipe 200 where the above-mentioned push rod 411, the diameter-expanded rod 412, and the plug rod 413 are located will also be filled with concrete. And part of the concrete will enter the above-mentioned receiving groove 4121 to increase the weight of the ground plug 400. And when the concrete is injected, a certain impact effect will be generated at the top end of the diameter-expanded rod 412, so that the ground plug 400 can further move downward, and further the ground plug 400 can be inserted deeper into the civil engineering foundation. It should be noted that the above-mentioned plug rod 413 is a solid rod.

[0052] In addition, the above-mentioned insertion rod 413 can also be a pipe body connected to the above-mentioned accommodation groove 4121, with the tip provided at the bottom end of the pipe body. In this way, the insertion rod 413 can not only be inserted into the ground of the civil engineering foundation, but also the concrete entering the accommodation groove 4121 will enter the interior of the insertion rod 413 and finally flow out from the inner hole of the insertion rod 413 into the civil engineering foundation, better playing a fixing role.

[0053] Optionally, the above-mentioned insertion rod 413 is a bent pipe. In this way, when the insertion rod 413 moves downward, the tip does not insert straight down into the ground of the civil engineering foundation, but inserts obliquely downward into the ground of the civil engineering foundation, so that it can be more easily inserted into the ground of the civil engineering foundation 400. Specifically, the radian of the above-mentioned bent pipe is 5-15°, for example, the radian of the bent pipe is 5° or 6° or 7° or 8° or 9° or 10° or 11° or 12° or 13° or 14° or 15°.

[0054] Of course, the above-mentioned ground plug 400 can also include a straight rod and a hollow sliding frame. The hollow sliding frame is adapted to the inner hole of the above-mentioned installation pipe 200, and the hollow sliding frame is slidably installed in the inner hole of the installation pipe 200. The straight rod is fixedly connected to the bottom end of the hollow sliding frame, and the bottom end of the straight rod is provided with a tip. At this time, the above-mentioned air-filled balloon body 500 is located above the hollow sliding frame and is in contact with the top surface of the hollow sliding frame. In this way, when the air-filled balloon body 500 expands and deforms downward, it will push the hollow sliding frame and the straight rod to move downward synchronously, so that the tip of the straight rod extends out of the above-mentioned installation pipe 200 and the base 100 and inserts into the ground of the civil engineering foundation.

[0055] An optional implementation manner of this embodiment is as follows: The bottom surface of the above-mentioned installation pipe 200 is flush with the bottom surface of the base 100. In this way, when the tip of the ground plug 400 extends out of the bottom surface of the installation pipe 200, it will also extend out of the base 100 at the same time. However, when the bottom surface of the base 100 is in contact with the ground of the civil engineering foundation, the bottom surface of the installation pipe 200 will also be in contact with the ground of the civil engineering foundation, which is not conducive to the concrete flowing from the installation pipe 200 into the above-mentioned pouring cavity 110. Therefore, a slurry flow hole 210 is also opened on the pipe wall of the installation pipe 200, and the slurry flow hole 210 communicates the pouring cavity 110 and the inner hole of the installation pipe 200, so that the concrete can smoothly flow from the installation pipe 200 into the above-mentioned pouring cavity 110.

[0056] Of course, the bottom surface of the above-mentioned installation pipe 200 can also be arranged above the bottom surface of the base 100. When the bottom surface of the base 100 is in contact with the ground, the bottom surface of the installation pipe 200 is not in contact with the ground.

[0057] An alternative implementation of this embodiment is as follows: A guiding block 700 is further fixedly provided in the above-mentioned installation pipe 200. The guiding block 700 is provided with an arc-shaped through hole 710 adapted to the elbow pipe. The elbow pipe 400 is slidably inserted into the arc-shaped through hole 710. In this way, it can play a guiding role in the up-and-down movement of the ground plug 400. Moreover, when the fixing block 330 is not inserted into the embedding section, the arc-shaped through hole 710 can also play a certain supporting role for the elbow pipe, so that the ground plug 400 can overcome its own gravity and be placed in the above-mentioned installation pipe 200. The guiding block 700 is located below the slurry flow hole 210, or the guiding block 700 is aligned with the slurry flow hole 210 and the thickness of the guiding block 700 is less than the aperture of the slurry flow hole 210, that is, the slurry flow hole 210 will not be blocked by the guiding block 700, so that the concrete can smoothly enter the above-mentioned pouring cavity 110 from the installation pipe 200 through the slurry flow hole 210.

[0058] An alternative implementation of this embodiment is as follows: A secondary pouring hole 350 communicating with the main pouring hole 340 is provided in the lower side wall of the fixing block 330. After the fixing block 330 is inserted into the embedding section, a small gap will be formed between the outer wall of the fixing block 330 and the inner wall of the embedding section. The setting of the above-mentioned secondary pouring hole 350 enables the concrete in the main pouring hole 340 to pass through the secondary pouring hole 350 and enter the gap between the outer wall of the fixing block 330 and the inner wall of the embedding section. After the concrete in this part solidifies, the fixing block 330 will be firmly connected in the embedding section, so that the mounting frame 300 is more firmly connected to the base 100.

[0059] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
