Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanized hangers, in particular to a steel pipe composite pile used in an abrasive environment. Background Art

[0002] Composite piles are made of two or more materials, designed to enhance the pile's bearing capacity and improve its deformation resistance. Typically, a composite pile consists of an outer casing or shell filled with one or more materials (such as cement slurry, gravel, sand, etc.). This combination of materials effectively enhances the pile's strength and rigidity, enabling it to withstand greater loads while minimizing deformation.

[0003] A steel pipe composite pile for collapsible loess, as disclosed in an existing Chinese patent application (authorization announcement number: CN213143033U), comprises a pile foundation body, a fixed housing sleeved on the outside of the pile foundation body, the fixed housing fixedly connected to the ground, a T-shaped engaging groove formed inside the fixed housing, a movable rod movably connected inside the transverse groove of the engaging groove, a fixed plate fixedly connected inside the transverse groove of the engaging groove, the fixed plate movably connected to the movable rod, a limit block and a tensioning spring sleeved on the movable rod, the fixed housing and the engaging block sleeved on the outside of the pile foundation body, a button, an engaging groove, a rubber gasket, a limit block, a movable rod, a tensioning spring, a fixed plate, and a fixing bolt installed inside the fixed housing, and springs installed on both sides of the engaging block to facilitate installation and fixation of the pile foundation body and limit the pile foundation body to prevent tilting.

[0004] When installing existing steel pipe composite piles, it is necessary to first install the steel pipe vertically in the ground, then sink the pile body into the steel pipe, and then pour cement slurry into the steel pipe to overflow the top of the pile body, so that the steel pipe and the pile body concrete become a whole. However, during the construction process of the existing device, it is necessary to sink the pile body into the steel pipe and then pour cement slurry. As a result, during the process of pouring cement slurry, the cement slurry is easy to squeeze the pile body and cause it to deviate, thereby affecting the stability between the pile body and the steel pipe. Utility Model Content

[0005] The purpose of this application is to solve the problem that when pouring cement slurry into existing steel pipe composite piles, the pile body position is easily offset, affecting the stability of the device. This application provides a steel pipe composite pile for use in an abrasive environment.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A steel pipe composite pile for use in an abrasive environment comprises a pile body, a steel pipe is arranged on the pile body, a grouting groove is opened on the pile body, a conical block is fixedly connected to the end of the pile body, the conical block is adapted to the steel pipe, and a mounting structure is provided between the pile body and the steel pipe.

[0008] By adopting the above technical solution, when the pile body and steel pipe on the device are installed, the steel pipe is first lifted and then vertically sunk into the pile foundation. Then the pile body is lifted and vertically sunk into the steel pipe so that it is located in the center of the steel pipe. The steel pipe and the pile body are limited by the installation structure, and cement slurry is poured into the pouring groove on the pile body so that the position of the pile body does not change when the cement slurry is injected, thereby reducing the gap between the pile body and the steel pipe, making the steel pipe composite pile more stable and durable.

[0009] Furthermore, a side plate is fixedly connected to the steel pipe, a fixing column is fixedly connected to the side plate, a fixing plate is fixedly connected above the pile body, a mounting groove is opened on the fixing plate, and the mounting groove is adapted to the fixing column.

[0010] By adopting the above technical solution, the mounting groove on the fixing plate is sleeved on the fixing column. Through the cooperation of the four fixing plates, the pile body is always located in the center position of the steel pipe. Then, cement slurry is poured into the steel pipe so that the cement fills the gap between the steel pipe and the pile body, thereby forming a composite pile with an outer steel pipe and an inner pile body, which makes the position of the pile body in the composite pile more stable.

[0011] Furthermore, the fixed column is rotatably connected to a rotating column, the rotating column is slidably connected to a limiting plate, the limiting plate is fixedly connected to a pulling plate, the fixed plate is provided with a limiting slot, and the limiting slot is adapted to the limiting plate.

[0012] By adopting the above technical solution, the limit plate is pulled toward the limit block, and the rotating column is rotated to rotate it ninety degrees. Then the limit plate is loosened, and the position between the limit plate and the limit groove is limited to limit the position between the fixed plates, thereby limiting the position between the steel pipe and the pile body.

[0013] Furthermore, the end of the rotating column is fixedly connected to a limit block, and a spring is sleeved on the rotating column. Both ends of the spring are fixedly connected to the limit block and the limit plate respectively.

[0014] By adopting the above technical solution, the spring reset pushes the limit plate to move into the limit groove, so that the limit plate limits the fixed plates.

[0015] Furthermore, a diversion groove is provided on the pile body, the diversion groove is communicated with the pouring groove, an adjusting column is fixedly connected in the diversion groove, an arc plate is rotatably connected to the adjusting column, and the arc plate is adapted to the diversion groove.

[0016] By adopting the above technical solution, as the cement slurry is poured into the grouting groove, the cement slurry flows into the space between the pile body and the inner plate through the diversion groove as the pouring amount increases, and at the same time pushes the arc plate to rotate along the adjustment, so that after the cement slurry solidifies, the pile body is more stable in the cement slurry.

[0017] Furthermore, a telescopic plate is rotatably connected to the pile body, and the telescopic portion of the telescopic plate is slidably connected to the arc plate.

[0018] By adopting the above technical solution, the telescopic plate is extended as the arc plate rotates, and the rotation angle of the arc plate is limited so that it can maintain the same state when the cement slurry solidifies.

[0019] Furthermore, a fixing ring is fixedly connected to the steel pipe, the fixing ring is adapted to the pile body, and diversion ports are provided between the conical blocks.

[0020] By adopting the above technical solution, the cement slurry overflowing from the diversion port will directly fill the bottom between the pile body and the steel pipe, which makes the cement slurry between the pile body and the steel pipe in the device more firmly fixed.

[0021] Furthermore, an inner plate is fixedly connected to the inner wall of the steel pipe, and a contact groove is opened on the inner plate, and the contact groove is arranged in a threaded manner.

[0022] By adopting the above technical solution, the capacity of the cement slurry is expanded by filling the contact groove, so that the inner plate and the pile body are better fixed together.

[0023] In summary, this application has at least one of the following beneficial effects:

[0024] 1. In the present application, when installing the steel pipe composite pile, the steel pipe is first lifted and then vertically sunk into the pile foundation. Then the pile body is lifted and also vertically sunk into the steel pipe so that it is located in the center of the steel pipe, and the installation groove on the fixed plate is set on the fixed column. Then the limit plate is pulled toward the limit block, and the rotating column is rotated to rotate it ninety degrees. Then the limit plate is loosened so that the spring resets and pushes the limit plate to move into the limit groove, so that the limit plate limits the fixed plates, thereby limiting the steel pipe and the pile body, and through the cooperation of the four fixed plates, the pile body is always in the center position of the steel pipe. Then cement slurry is poured into the steel pipe so that the cement fills the gap between the steel pipe and the pile body, thereby forming a composite pile with an outer steel pipe and an inner pile body, which makes the position of the pile body in the composite pile more stable and improves the stability of the device.

[0025] 2. In the present application, when cement slurry is poured into the pile body, as the cement slurry is poured into the pouring groove, the cement slurry flows into the space between the pile body and the inner plate through the diverter groove as the pouring amount increases, and at the same time pushes the arc plate to rotate along the adjustment, and pulls the telescopic plate to extend as the arc plate rotates, and limits the rotation angle of the arc plate, so that after the cement slurry solidifies, the pile body is more stable in the cement slurry, and the capacity of the cement slurry is expanded by filling the contact groove, so that the inner plate and the pile body are better fixed together, and the cement slurry overflowing from the diverter port will directly fill the bottom between the pile body and the steel pipe, which makes the cement slurry between the pile body and the steel pipe in the device more firmly fixed, and the setting of the inner plate also makes the device have better anti-abrasion effect.

[0035] When installing the pile body 1 and the steel pipe 2 on the device, the steel pipe 2 is first lifted and then vertically sunk into the pile foundation. Then the pile body 1 is lifted and also vertically sunk into the steel pipe 2 so that it is located at the center of the steel pipe 2. The steel pipe 2 and the pile body 1 are limited by the installation structure, and cement slurry is poured into the pouring groove on the pile body 1 so that the position of the pile body 1 does not change when the cement slurry is injected, thereby reducing the gap between the pile body 1 and the steel pipe 2, making the steel pipe 2 composite pile more stable and durable.

[0036] Reference Figure 1 and Figure 2 The steel pipe 2 is fixedly connected to a side plate 3, and a fixed column 4 is fixedly connected to the side plate 3.

[0037] After the pile body 1 is in the center of the steel pipe 2, the steel pipe 2 is lifted and then vertically sunk into the pile foundation. Then the pile body 1 is lifted and vertically sunk into the steel pipe 2 so that it is located in the center of the steel pipe 2, and the installation groove 17 on the fixing plate 8 is sleeved on the fixing column 4. Then the limiting plate 11 is pulled to move toward the limiting block 10, and the rotating column 9 is rotated to make it rotate ninety degrees. Then the limiting plate 11 is loosened, so that the spring 13 is reset and pushes the limiting plate 11 to move into the limiting groove 18, so that the limiting plate 11 limits the position between the fixing plate 8, thereby limiting the position between the steel pipe 2 and the pile body 1, and through the cooperation of the four fixing plates 8, the pile body 1 is always in the center position of the steel pipe 2, and then cement slurry is poured into the steel pipe 2 so that the cement fills the gap between the steel pipe 2 and the pile body 1, thereby forming a composite pile with the pile body 1 inside the outer steel pipe 2, which makes the position of the pile body 1 in the composite pile more stable and improves the stability of the device.

Then loosen the limit plate 11, so that the spring 13 resets and pushes the limit plate 11 to move to the limit groove 18, so that the limit plate 11 limits the fixed plate 8, thereby limiting the position between the steel pipe 2 and the pile body 1, and through the cooperation of the four fixing plates 8, the pile body 1 is always in the center position of the steel pipe 2, and then pour cement slurry into the steel pipe 2 so that the cement fills the gap between the steel pipe 2 and the pile body 1, thereby forming a composite pile with the pile body 1 inside the outer steel pipe 2, which makes the position of the pile body 1 in the composite pile more stable and improves the stability of the device.

[0041] When cement slurry is poured into the pile body 1, as the cement slurry is poured into the pouring groove, the cement slurry flows into the space between the pile body 1 and the inner plate 5 through the diversion groove as the pouring amount increases, and at the same time pushes the curved plate 14 to rotate along the adjustment, and pulls the telescopic plate 16 to extend as the curved plate 14 rotates, limiting the rotation angle of the curved plate 14, so that after the cement slurry solidifies, the pile body 1 is more stable in the cement slurry, and the capacity of the cement slurry is expanded by filling the contact groove 6, so that the inner plate 5 and the pile body 1 are better fixed together, and the cement slurry overflowing from the diversion port will directly fill the bottom between the pile body 1 and the steel pipe 2, which makes the cement slurry between the pile body 1 and the steel pipe 2 in the device more firmly fixed, and the setting of the inner plate 5 also makes the device have a better anti-abrasion effect.
