Description

Technical Field

[0001] This invention belongs to the field of concrete jacking technology, and more specifically, it relates to an in-pipe collaborative device for corrugated steel frame and reinforcing bar and its working method. Background Technology

[0002] Concrete pipe jacking is a type of pipe made of reinforced concrete that is constructed underground using trenchless technology. It is widely used in municipal drainage, sewage, and farmland irrigation systems. Corrugated steel frames and reinforcing bars are installed in concrete pipe jacking to enhance the integrity and durability of the structure.

[0003] The following problems still exist after corrugated steel frames are connected to reinforcing bars: 1. The lack of auxiliary straightening structures makes it inconvenient for workers to adjust the concentricity of the corrugated steel frames; 2. They usually do not have welding auxiliary functions, which means that the outer wall of the longitudinal reinforcing bars cannot fully contact the corrugated steel frames, affecting the welding accuracy; 3. When the bottom of the corrugated steel frames and longitudinal reinforcing bars is not equipped with a support structure, the corrugated steel frames and longitudinal reinforcing bars cannot be completely embedded in the concrete, and the corrugated steel frames and longitudinal reinforcing bars are prone to movement in the forming mold, which cannot guarantee the concentricity of the corrugated steel frames and the forming mold. Summary of the Invention

[0004] This disclosure relates to an in-pipe coordination device for corrugated steel reinforcement and reinforcing bars, and its working method. The device comprises a coordinating force-bearing section, a concentric adjustment section, a welding auxiliary section, a multi-purpose support section, and a support detection section. When a row of U-shaped limiting frames slides simultaneously with a row of arc-shaped connecting plates, the concentric adjustment rod provides all-around auxiliary straightening for the corrugated steel reinforcement. This facilitates the longitudinal reinforcing bars to be welded approaching the concentric adjustment rod, allowing the outer wall of the longitudinal reinforcing bars to fully contact the corrugated steel reinforcement, thus ensuring the welding quality between the corrugated steel reinforcement and the longitudinal reinforcing bars. When the lower set of support detection sections is not connected to the corrugated steel reinforcement, the corrugated steel... The corrugated steel frame tilts to one side under the action of the two multi-purpose support rods below, prompting the staff to connect the two sets of support detection parts to the corrugated steel frame. When the length direction of the four multi-purpose support rods is perpendicular to the axis of the corrugated steel frame, the outer wall of the four multi-purpose support rods can contact the inner wall of the forming mold, ensuring that the corrugated steel frame and the forming mold are always concentric. This solves the problems of inconvenience for staff to adjust the concentricity of the corrugated steel frame, the inability of the outer wall of the longitudinal reinforcement to fully contact the corrugated steel frame, the inability of the corrugated steel frame and the longitudinal reinforcement to be completely embedded in the concrete, and the easy movement of the corrugated steel frame and the longitudinal reinforcement in the forming mold.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

Furthermore, since two rows of irregularly shaped connecting frames 202 are fixedly installed on a row of arc-shaped connecting plates 201, and a row of U-shaped limiting frames 203 are fixedly installed on the two rows of irregularly shaped connecting frames 202, the row of U-shaped limiting frames 203 can slide simultaneously with the row of arc-shaped connecting plates 201. Also, since the concentric adjustment rod 204 is inserted into the row of U-shaped limiting frames 203, and the outer wall of the concentric adjustment rod 204 contacts the corrugated steel frame 101 and the row of U-shaped limiting frames 203, it plays an auxiliary straightening role on the corrugated steel frame 101 at the row of U-shaped limiting frames 203, which is conducive to improving the concentricity of the corrugated steel frame 101. When the row of U-shaped limiting frames 203 slides simultaneously with the row of arc-shaped connecting plates 201, the concentric adjustment rod 204 plays an all-round auxiliary straightening effect on the corrugated steel frame 101.

On the one hand, it positions the longitudinal rebar 102 to be welded, improving the positioning efficiency of the longitudinal rebar 102; on the other hand, it facilitates the longitudinal rebar 102 to be welded approaching the concentric adjusting rod 204, allowing the longitudinal rebar 102 to move closer to the concentric adjusting rod 204, thus improving the positioning efficiency of the longitudinal rebar 102. The outer wall of 2 can fully contact the corrugated steel frame 101, ensuring the welding quality between the corrugated steel frame 101 and the longitudinal steel bar 102; and because the four movable positioning blocks 303 are slidably installed on the two steel bar positioning frames 301, and the four helical springs a304 are installed inside the two steel bar positioning frames 301, and the inner ends of the four helical springs a304 are in contact with the outer sides of the four movable positioning blocks 303, they play an elastic limiting role for the longitudinal steel bar 102.

Its specific functions are as follows: Since the four circular connecting shafts 401 are rotatably installed on the corrugated steel frame 101, and the four multi-purpose support rods 402 are fixedly installed on the outer wall of the four circular connecting shafts 401, when a ring of longitudinal steel bars 102 is welded to the corrugated steel frame 101, the workers align the length direction of the four multi-purpose support rods 402 with the axial direction of the corrugated steel frame 101, which is conducive to the workers rotating the corrugated steel frame 101; and since the eight circular support shafts 501 are inserted into the corrugated steel frame 101, and the eight arc-shaped connecting bars 502 are fixedly installed on the eight circular support shafts 501, four of the circular support shafts 501 provide support for the corrugated steel frame 101, ensuring that the corrugated steel frame 101 and a ring of longitudinal steel bars 102 are all in the concrete; Furthermore, since the eight circular positioning blocks 406 are fixedly installed on the four movable supports 404, and the inner ends of the eight circular positioning blocks 406 are inserted into the corrugated steel frame 101, when the lower set of support detection parts 500 is not connected to the corrugated steel frame 101, the corrugated steel frame 101 tilts to one side under the action of the two lower multi-purpose support rods 402, which can prompt the operator to connect the two sets of support detection parts 500 to the corrugated steel frame 101; and since the eight limit detection plates 503 are fixedly installed on the outside of the eight circular support shafts 501, and the inner sides of the eight limit detection plates 503 are connected to the corrugated steel frame 101, the corrugated steel frame 101 tilts to one side under the action of the two lower multi-purpose support rods 402, which can prompt the operator to connect the two sets of support detection parts 500 to the corrugated steel frame 101. When the corrugated steel frame 101 is in contact with the eight circular support shafts 501, the operator needs to rotate the four multi-purpose support rods 402 ninety degrees so that the length direction of the four multi-purpose support rods 402 is perpendicular to the axis of the corrugated steel frame 101. Otherwise, the four multi-purpose support rods 402 will affect the movement of the eight limit detection plates 503. When the length direction of the four multi-purpose support rods 402 is perpendicular to the axis of the corrugated steel frame 101, the outer wall of the four multi-purpose support rods 402 can contact the inner wall of the forming mold, ensuring that the corrugated steel frame 101 and the forming mold are always concentric.

[0027] This invention provides a method for operating an in-pipe coordination device for corrugated steel reinforcement and steel bars, comprising the following steps: 1) Insert the concentric adjustment rod 204 into a row of U-shaped limit brackets 203, and then rotate the concentric adjustment rod 204 so that the concentric adjustment rod 204 rotates around the corrugated steel frame 101 one revolution; 2) Insert the longitudinal steel bar 102 to be welded into the two steel bar positioning frames 301, and then weld the longitudinal steel bar 102 to the corrugated steel frame 101; 3) Pull the four movable supports 404 outwards, and then rotate the four multi-purpose support rods 402 ninety degrees so that the length direction of the four multi-purpose support rods 402 is perpendicular to the axis of the corrugated steel frame 101. 4) Insert eight circular support shafts 501 into the corrugated steel frame 101.

[0028] The specific usage and function of this embodiment are as follows: In use, the concentric adjustment rod 204 is first inserted into a row of U-shaped limiting brackets 203, which assists in straightening the corrugated steel ribs 101 at the row of U-shaped limiting brackets 203, thus improving the concentricity of the corrugated steel ribs 101. Then, the concentric adjustment rod 204 is rotated, causing it to rotate one full circle around the corrugated steel ribs 101. When the row of U-shaped limiting brackets 203 slides simultaneously with the row of arc-shaped connecting plates 201, the concentric adjustment rod 204 provides all-around assist in straightening the corrugated steel ribs 101. When welding the longitudinal reinforcing bars 102 to the corrugated steel ribs 101, the worker aligns the length direction of the four multi-purpose support rods 402 with the axial direction of the corrugated steel ribs 101, which facilitates the worker's rotation of the corrugated steel ribs 101. The longitudinal reinforcing bars 102 to be welded are inserted into the two reinforcing bar positioning frames 301. On the one hand, this positions the longitudinal reinforcing bars 102, improving their positioning efficiency. On the other hand, it allows the longitudinal reinforcing bars 102 to approach the concentric adjustment rod 204, ensuring that the outer wall of the longitudinal reinforcing bars 102 can fully contact the corrugated steel frame 101, thus guaranteeing the welding quality between the corrugated steel frame 101 and the longitudinal reinforcing bars 102. Then, the longitudinal reinforcing bars 102 are welded to the corrugated steel frame 101. When the longitudinal reinforcing bars 102 are connected to or separated from the two reinforcing bar positioning frames 301, the four movable positioning blocks 303 automatically slide outward under force, allowing the corrugated steel frame 101 and a ring of longitudinal reinforcing bars 102 to be welded together. The internal workings of the concrete jacking pipe work together to enhance the structural strength and stability; utilizing the compressive, bending, and impact resistance of the corrugated steel frame 101 and the tensile strength of the longitudinal reinforcement 102, a highly efficient and reliable load-bearing system is formed; four movable supports 404 are pulled outward, and four multi-purpose support rods 402 are rotated 90 degrees so that the length direction of the four multi-purpose support rods 402 is perpendicular to the axis of the corrugated steel frame 101; eight circular support shafts 501 are inserted into the corrugated steel frame 101, of which four circular support shafts 501 provide support for the corrugated steel frame 101, ensuring that the corrugated steel frame 101 and a ring of longitudinal reinforcement 102 are all embedded in the concrete; when the lower set of support detection parts 500 is not connected to the corrugated steel frame 101... When connected, the corrugated steel frame 101 tilts to one side under the action of the two multi-purpose support rods 402 below, which prompts the operator to connect the two sets of support detection parts 500 to the corrugated steel frame 101. When the eight circular support shafts 501 are connected to the corrugated steel frame 101, the operator needs to rotate the four multi-purpose support rods 402 ninety degrees so that the length direction of the four multi-purpose support rods 402 is perpendicular to the axis of the corrugated steel frame 101. Otherwise, the four multi-purpose support rods 402 will affect the movement of the eight limit detection plates 503. When the length direction of the four multi-purpose support rods 402 is perpendicular to the axis of the corrugated steel frame 101, the outer wall of the four multi-purpose support rods 402 can contact the inner wall of the forming mold, ensuring that the corrugated steel frame 101 and the forming mold are always concentric.
