[0046] The construction method of the jacking pipe construction auxiliary device in the present application comprises the following steps:

[0047] Step one: a back wall is arranged on the inner wall of the inner bottom of the working well, the back wall corresponds to the position of the to-be-drilled hole on the inner wall of the working well, and a hoisting device is arranged at the top end of the working well;

[0048] Step two: the guide rail 2 and the back seat wall 1 are placed on the inner bottom of the working well through hoisting equipment, and the position of the guide rail 2 is assembled and adjusted;

[0049] Step three: the back seat wall 1 is fixed on the side of the back wall, the guide rail 2 is installed on the connecting rod 12, the connecting plate 3 is turned over by the worker, and the reinforcing block 17 on the guide rail 2 is connected through the mounting barrel 19 and the adjusting rod 20 on the connecting plate 3;

[0050] Step four: the worker rotates the adjusting rod 20, and adjusts the spacing between the two guide rails 2 at different positions through the scale bar 24 on the outer wall of the adjusting rod 20;

[0051] Step five: the worker connects and fixes the connecting plate 3, the guide rail 2 and the bottom plate 13 through the supporting rod 22, and replaces the base 14 according to the use condition, so that the top of the two guide rails 2 at different positions is kept at a horizontal height, and the base 14 is fixed on the inner bottom of the working well;

[0052] Step six: the worker installs the back seat jack 8, and places the pipe jacking machine on the two guide rails 2 through hoisting equipment, so that the back seat jack 8 can drive the pipe jacking machine to move, and the pipe jacking machine can drill the inner wall of the working well.

[0053] In use, the worker places the two guide rails 2 and the back seat wall 1 on the inner bottom of the working well through the hoisting machine, and the worker pours cement on the inner wall of the working well in advance to form a back wall corresponding to the position to be drilled on the inner wall of the working well. The worker rotates the connecting plate 3 in the placing groove 4 on the side of the back seat wall 1, so that the connecting plate 3 rotates around the connecting rod 12 at the bottom end of the connecting plate 3 until the connecting plate 3 is perpendicular to the back seat wall 1. The worker fixes the back seat wall 1 on the surface of the back wall through the fixing bolt and the mounting hole 15 on the inner wall of the placing groove 4, so that the side of the back seat wall 1 close to the connecting plate 3 faces the direction of the position to be drilled on the inner wall of the working well.

[0054] The staff lays several bottom plates 13 on the side of the back wall 1 in the working well in advance, and installs two guide rails 2 on the two sides of the connecting plate 3, and the guide rails 2 are located on the top of the several bottom plates 13. In use, the staff can adjust the position of the bottom plate 13, so that the bottom plate 13 corresponds to the reinforcing block 17 on the side of the guide rail 2, and the end of the two guide rails 2 close to the back wall 1 is located in the groove 11 on the side of the back wall 1. The position of the two guide rails 2 in the groove 11 is slidingly installed on the two ends of the connecting rod 12. In use, the connecting rod 12 can not only connect and position the connecting plate 3, but also install and support the two guide rails 2. Because the guide rail 2 is slidingly installed on the connecting rod 12, the guide rail 2 and the back wall 1 are perpendicular to each other in use, and the guide rail 2 can better support the back wall 1. Meanwhile, the staff can replace the guide rail 2 at any time according to the use condition. Because the end of the guide rail 2 and the connecting plate 3 close to the back wall 1 is installed on the connecting rod 12, the connecting rod 12 can limit the horizontal position of the guide rail 2 and the connecting plate 3, which is more convenient for the staff to connect and fix the guide rail 2 and the connecting plate 3.

[0055] When the staff finishes installing the guide rail 2, the staff can rotate the several installation cylinders 19 in the protection groove 18 on the two sides of the connecting plate 3, so that the installation cylinder 19 rotates around the fixed rod 25 thereon. The staff rotates the adjusting rod 20 on the installation cylinder 19 according to the required distance between the two guide rails 2. Because the end of the adjusting rod 20 close to the connecting plate 3 is threadedly installed in the installation cylinder 19, the adjusting rod 20 can rotate and move in the installation cylinder 19 when rotating, and the staff can adjust the moving distance of the adjusting rod 20 according to the scale bar 24 on the adjusting rod 20.

[0056] When the staff finishes adjusting the position of the adjusting rod 20, the staff can rotate the installation cylinder 19 again, so that the installation cylinder 19 drives the connecting block 21 to rotate through the adjusting rod 20, until the installation cylinder 19 and the adjusting rod 20 are perpendicular to the connecting plate 3. The staff pushes the two guide rails 2 to move towards the connecting plate 3, and when the guide rail 2 moves, the end of the guide rail 2 close to the back wall 1 can slide on the connecting rod 12. In use, the staff can adjust the position of the guide rail 2 until the connecting block 21 on the adjusting rod 20 moves into the fixed groove 27 on the reinforcing block 17 on the side of the guide rail 2.

[0057] When the connecting block 21 is moved to the inside of the fixing groove 27, the position of the guide rail 2 can be finely adjusted until the connecting hole 23 on the connecting block 21 corresponds to the connecting hole 23 on the reinforcing block 17, and the connecting hole 23 corresponds to the adjusting hole 26 on the bottom plate 13. In use, the top of both ends of the bottom plate 13 is provided with a plurality of adjusting holes 26, and the positions of the plurality of adjusting holes 26 correspond to different distances and different models between the two guide rails 2. Therefore, when the specified size of the top pipe is installed, the connecting hole 23 on the connecting block 21 and the reinforcing block 17 corresponds to the adjusting hole 26 at the specified position on the bottom plate 13.

[0058] The staff inserts the supporting rod 22 into the connecting hole 23, which can connect and fix the connecting block 21 and the reinforcing block 17 in use. The supporting rod 22 can connect and support the connecting plate 3 and the guide rail 2 in use. One end of the connecting plate 3 is installed on the connecting rod 12, and the plurality of mounting barrels 19 can support the two sides of the connecting plate 3 through the fixing rod 25. In use, it can prevent the connecting plate 3 from shaking or moving in use, making the connecting plate 3 more stable.

[0059] The bottom end of the supporting rod 22 is located in the adjusting hole 26 on the bottom plate 13 in use, which can fix the position of the guide rail 2 and the bottom plate 13 in use, prevent the bottom plate 13 and the guide rail 2 from moving in use, and make the distance between the two guide rails 2 not change in use. The ends of the bottom plate 13 can support the connecting plate 3 in use, and the two ends can support the two guide rails 2 respectively. The bottom end of the reinforcing block 17 abuts against the top of the bottom plate 13 in use, so that the connecting position of the guide rail 2 and the bottom plate 13 always remains vertical, making the guide rail 2, the bottom plate 13 and the connecting plate 3 more stable in use.

[0060] When the staff installs and adjusts the guide rail 2, the staff can install the mounting plate 7 provided with the rear seat jack 8 in the mounting groove 5 on the side of the rear seat wall 1, and in use, the staff can adjust the number of the rear seat jacks 8 according to the use. In use, the limiting plate 6 on the inner wall of the mounting groove 5 can better support and limit the position of the mounting plate 7. The staff places the pipe jacking machine on the top of the two guide rails 2 through the hoisting machine, and then the staff can push the pipe jacking machine to slide on the top of the two guide rails 2 through the rear seat jacks 8, so that the pipe jacking machine moves to the position of the hole to be drilled on the inner wall of the work well and drills the hole. When the staff uses the guide rail 2, the staff can disassemble the rear seat wall 1 and the supporting rod 22, so that the connecting plate 3, the guide rail 2 and the bottom plate 13 are disconnected, the staff rotates the mounting cylinder 19, so that the mounting cylinder 19 and the adjusting rod 20 are rotated to the inside of the protection groove 18 on the side of the connecting plate 3, the connecting plate 3 is rotated, so that the connecting plate 3 is rotated to the inside of the placing groove 4 on the side of the rear seat wall 1, and the guide rail 2 is slid off from the connecting rod 12. In use, the staff can quickly disassemble the guide rail 2 and the rear seat wall 1, and the staff can use more conveniently.

[0061] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
