Description

TECHNICAL FIELD

[0001] The present application relates to the infrastructure technical field, especially to a combined foundation for overhead pipeline equipment. BACKGROUND

[0002] In the overhead pipeline engineering, the support rod is installed on the foundation, and the foundation supports the support rod, and the existing foundation is generally a platform for installing the support rod and a screw pile for supporting the platform. In cold weather areas, after the screw pile is inserted into the ground, due to the cold and humid climate conditions, the water in the soil will freeze at night, forming ice crystals, causing the soil volume to expand, generating an upward pulling force on the foundation, causing the foundation to move upward. When the temperature rises, the surface soil melts, the volume decreases, and the soil sinks, which will cause the foundation to move downward, affecting the stability of the foundation, and causing the foundation to collapse. SUMMARY

[0003] The purpose of the present application is to solve the problem of the existing technology that the foundation moves due to frost heaving, affecting the stability of the foundation, and a combined foundation for overhead pipeline equipment is proposed.

[0004] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0005] A combined foundation for overhead pipeline equipment is designed, which comprises a support table, a plurality of fixed parts are fixedly connected to the support table by bolts, and a plurality of support piles are fixedly connected to the lower ends of the fixed parts;

[0006] A connecting sleeve is provided on each of the support piles, a plurality of spiral leaves are fixedly connected to the connecting sleeves, an upper retaining ring is fixedly connected to one end of the support pile, and a lower retaining ring is fixedly connected to the other end of the support pile;

[0008] Preferably, a limiting groove is vertically provided in the inner wall of the connecting sleeve, a limiting block is provided in the limiting groove, and the limiting block is fixedly connected to the support pile.

[0009] Preferably, the connecting sleeve, the support pile, and the spiral leaves are made of stainless steel material.

[0010] Preferably, the anti-freeze pulling mechanism includes a movable block that penetrates the connecting shell. A first rack is fixedly connected to the movable block, a gear meshes with the first rack, a rotating shaft is fixedly connected to the gear, and a fixed lug is rotatably connected to the rotating shaft via a bearing. The fixed lug is fixedly connected to the connecting shell. A second rack meshes with the gear and is fixedly connected to the fixed post. A spring is fixedly connected to the second rack and is fixedly connected to the connecting shell.

[0011] Preferably, a connecting ring is fixedly connected to the connecting shell, and a retaining ring is fixedly connected to the connecting ring, the retaining ring abutting against the lower retaining ring.

[0012] Preferably, the support pile has an installation hole, a connecting rod is installed in the installation hole, the support pile has an installation cavity, the installation cavity is connected to the installation hole, an abutment plate is rotatably connected to the connecting rod via a bearing, the abutment plate abuts against the inner wall of the installation cavity, both ends of the abutment plate abut against the first rack, a nut is fixedly connected to the support pile, the connecting rod is threadedly connected to the nut, and a rotating block is fixedly connected to the connecting rod, the rotating block abuts against the nut.

[0015] The present invention proposes a combined foundation for overhead pipeline equipment, which has the following advantages: when the soil freezes and causes frost pull, it will cause the connecting sleeve to move.

After thawing, the connecting sleeve will automatically fall under the action of gravity and abut against the lower retaining ring. It will not act on the support pile, thus preventing the support pile from moving and ensuring the stability of the support pile, thereby ensuring the stability of the foundation and preventing it from tilting.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments.

[0027] Embodiment 1: Refer to Figures 1-5 An overhead pipeline equipment combined foundation, comprising a support table 1, a plurality of fixed parts 7 are fixedly connected on the support table 1 through bolts, and a support pile 6 is fixedly connected at the lower end of each of the plurality of fixed parts 7, and the fixed parts 7 and the support table 1 are connected through bolts.

[0028] A plurality of support piles 6 are sleeved with a plurality of connecting sleeves 2, a plurality of helical blades 3 are fixedly connected to the plurality of connecting sleeves 2, the helical blades 3 increase the contact area with the ground, which is beneficial to improve the stability, one end of the plurality of support piles 6 is fixedly connected with an upper retaining ring 8, and the other end is fixedly connected with a lower retaining ring 13, the upper retaining ring 8 and the lower retaining ring 13 are used to limit the connecting sleeve 2, so that the connecting sleeve 2 can only move between the upper retaining ring 8 and the lower retaining ring 13, when the soil freezes and produces frost heaving, the connecting sleeve 2 is driven to move upward, and since the support pile 6 is not affected, the support pile 6 will not be affected by frost heaving, after melting, the connecting sleeve 2 automatically falls under the action of gravity and abuts against the lower retaining ring 13, and the support pile 6 is not affected, so that the support pile 6 will not move, ensuring the stability of the support pile, thereby ensuring the stability of the foundation, and the situation of tilting will not occur.

[0029] The connecting sleeve 2, the support pile 6 and the helical blade 3 are made of stainless steel material, which prevents rusting, and other metal materials can also be made of stainless steel material.

[0030] In example 1, when the support pile 6 is driven into the ground, the connecting sleeve 2 is subjected to the force of the soil and moves upward to abut against the upper retaining ring 8 instead of the lower retaining ring 13, which causes the connecting sleeve 2 to be subjected to frost heaving and exert an upward force on the support pile 6, affecting the stability of the support pile 6, and Figures 1-9 , as another preferred embodiment of the present application, based on example 1.

[0031] A plurality of connecting sleeves 2 are fixedly connected with a plurality of connecting shells 4, two connecting ears 28 are fixedly connected to the plurality of connecting shells 4, a fixing column 19 is penetratingly arranged on the two connecting ears 28, a fixing hole 20 is formed on the support pile 6, the fixing column 19 is located in the fixing hole 20, and the fixing column 19 is moved out of the fixing hole 20 through the anti-frost heaving mechanism, when the connecting sleeve 2 is rotated and driven into the ground, the fixing column 19 is connected with the fixing hole 20, so that the connecting sleeve 2 abuts against the lower retaining ring 13 after entering the ground, preventing the connecting sleeve 2 from abutting against the upper retaining ring 8, and the connecting sleeve 2 is connected with the support pile 6 at all times without freezing, increasing the contact area with the soil, which is beneficial to stability and prevents sinking.

[0032] A limiting groove 21 is vertically formed on the inner wall of the connecting sleeve 2, a limiting block 9 is arranged in the limiting groove 21, and the limiting block 9 is fixedly connected to the support pile 6, the limiting block 9 and the limiting groove 21 are matched, so that the connecting sleeve 2 can only move in the vertical direction on the support pile 6, which is beneficial to prevent the fixing column 19 and the fixing hole 20 from deviating, and ensures that the fixing column 19 can enter the fixing hole 20 after being reset.

[0033] The anti-freeze pulling mechanism includes a movable block 11 that penetrates the connecting shell 4. A first rack 15 is fixedly connected to the movable block 11, and a gear 16 meshes with the first rack 15. A rotating shaft 18 is fixedly connected to the gear 16, and a fixed ear is rotatably connected to the rotating shaft 18 via a bearing. The fixed ear is fixedly connected to the connecting shell 4. A second rack 17 meshes with the gear 16 and is fixedly connected to a fixed post 19. A spring 14 is fixedly connected to the second rack 17 and is fixedly connected to the connecting shell 4. When the soil freezes, the expansion of the soil will cause the movable block 11 to move closer to the axis of the support pile 6. Block 11 pushes the first rack 15 to move, the first rack 15 drives the gear 16 to rotate, the gear 16 drives the second rack 17 to move, the spring 14 is compressed, causing the second rack 17 to drive the fixed column 19 to move, moving the fixed column 19 out of the fixed hole 20. When subjected to frost pull-out force, the connecting sleeve 2 disengages from the support pile 6, causing the connecting sleeve 2 to move upward, while the support pile 6 does not move upward, ensuring that when driven into the ground, the fixed column 19 is located in the fixed hole 20, playing a connecting role. When subjected to frost pull-out force, the fixed column 19 disengages from the fixed hole 20, and the connecting sleeve 2 is affected by the frost pull-out force, avoiding any impact on the support pile 6.

[0034] After melting, the connecting sleeve 2 will reset under the action of gravity. When the fixing post 19 is aligned with the fixing hole 20, the second rack 17 will move under the action of the restoring force of the spring 14, so that the fixing post 19 can be re-inserted into the fixing hole 20, and the connecting sleeve 2 and the support pile 6 can be reconnected. When the connecting sleeve 2 moves, soil may easily accumulate on the lower retaining ring 13, resulting in a height difference between the fixing hole 20 and the fixing post 19, making it difficult to align. The connecting shell 4 is fixedly connected to the connecting ring 5, and the connecting ring 5 is fixedly connected to the retaining ring 12. The retaining ring 12 abuts against the lower retaining ring 13. By using the retaining ring 12 and the connecting ring 5 to seal, soil is prevented from entering between the lower retaining ring 13 and the connecting shell 4, ensuring that there is no height difference between the fixing post 19 and the fixing hole 20 after the connecting sleeve 2 is reset, so that the fixing post 19 can be re-inserted into the fixing hole 20.

[0035] Example 3: In Example 2, since one end of the movable block 11 is located outside the connecting shell 4, when the support pile 6 is installed, the movable block 11 is squeezed and limited by the soil by rotary drilling, causing the movable block 11 to move. This causes the second rack 17 to move the fixed column 19, moving the fixed column 19 out of the fixing hole 20, detaching the connection between the connecting sleeve 2 and the support pile 6. Under the action of soil resistance, the connecting sleeve 2 moves upward until it abuts against the upper retaining ring 8. Therefore, when subjected to frost pull-out force, it is still easy to directly act on the support pile 6. (Refer to...) Figures 1-9 As another preferred embodiment of the present invention, based on embodiment 2.

[0036] A mounting hole 23 is provided on the support pile 6, and a connecting rod 10 is installed inside the mounting hole 23. A mounting cavity 24 is provided on the support pile 6, and the mounting cavity 24 is connected to the mounting hole 23. An abutment plate 22 is rotatably connected to the connecting rod 10 via a bearing. The abutment plate 22 abuts against the inner wall of the mounting cavity 24. The two ends of the abutment plate 22 abut against two first racks 15 respectively. A nut 25 is fixedly connected to the support pile 6, and the connecting rod 10 is threadedly connected to the nut 25. A rotating block 27 is fixedly connected to the connecting rod 10, and the rotating block 27 abuts against the nut 25. The abutment plate 22 and the first racks 15 are connected by abutment. The five-phase abutment limit the first rack 15, preventing the movable block 11 from moving inward due to soil compression during installation. This ensures that the fixing post 19 remains within the fixing hole 20 during installation. After installation, the rotating block 27 is turned with a wrench, causing the connecting rod 10 to rotate and rise, which in turn raises the abutment plate 22, creating a height difference between the abutment plate 22 and the first rack 15. This releases the limitation on the first rack 15, ensuring that the movable block 11 can move during frost heave but cannot move during installation.

[0037] The bearing is a thrust ball bearing. The mounting cavity 24 is used to limit the abutment plate 22, preventing the abutment plate 22 from rotating. The abutment plate 22 will be subjected to upward or downward forces, so a thrust ball bearing capable of axial force load is used.

[0038] Example 4: In Example 3, because the support pile 6 is installed by rotation and the connecting rod 10 is connected by a threaded connection, the connecting rod 10 is prone to rotation when the support pile 6 rotates, causing the position of the abutment plate 22 to change. (Refer to...) Figure 7 In another preferred embodiment of the present invention, based on embodiment 3, the rotating block 27 is provided with a retaining groove, and a hinge block 26 is provided in the retaining groove. The hinge block 26 is hinged to the fixed part 7. By using the hinge block 26 to cooperate with the retaining groove, the connecting rod 10 and the fixed part 7 can rotate synchronously, avoiding relative rotation, thereby avoiding the situation where the position of the abutment plate 22 changes during installation. After the support pile 6 is driven into the ground, the limit on the rotating block 27 is released by rotating the hinge block 26. Rotating the rotating block 27 causes the connecting rod 10 to rise, driving the abutment plate 22 to rise, releasing the limit on the first rack 15. When the abutment plate 22 abuts against the top wall of the mounting cavity 24, it will encounter great resistance when rotating the rotating block 27. The wrench can be stopped. Finally, the support platform 1 and the fixed part 7 are connected by bolts.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
