[0002] Pipe jacking is a trenchless construction method for underground projects, widely used in the construction of various obstacles such as roads, rivers or buildings. In the process of pipe jacking, the most critical part is the initial exit and reception of the tunnel, which will largely determine the success or failure of the pipe jacking construction. When the pipe jacking machine is received and retracted, it is usually necessary to use lifting equipment to disassemble the upper and lower shells of the pipe jacking and rotate them before retracting. However, due to the large space occupied by the large-section pipe jacking machine itself and the small space in some station structures, it is impossible to set up lifting equipment. Therefore, it is impossible to use conventional methods to receive and retract the pipe jacking machine. Even if lifting equipment is set up, the lack of space may cause the pipe jacking machine or the lifting equipment to conflict with the station structure, causing mechanical injuries to personnel and greatly affecting construction safety.

[0017] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0018] like Figure 1 、 2 As shown, a receiving and retracting structure of a large-section rectangular pipe jacking machine under non-hoisting conditions includes a pipe jacking machine 1, a receiving rotating platform 2, a lifting bracket 3, a vertical jack 4, a track 5, a first rail clamp 6, a second rail clamp 7, a horizontal jack 8 and a rotating jack 9.

[0019] The pipe jacking machine 1 is located on the receiving rotary platform 2. The pipe jacking machine 1 includes an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 are detachably connected together by spacers and bolts.

[0020] Four jacking brackets 3 are provided, and the four jacking brackets 3 are symmetrically arranged on the left and right sides of the upper shell 11 of the pipe jacking machine 1.

[0021] The number and position of the vertical jacks 4 correspond to the jacking brackets 3. The vertical jacks 4 are fixed on the receiving rotary platform 2 and are used to press on the jacking brackets 3 to lift the pipe jacking machine 1 as a whole or the upper shell 11.

[0022] Two tracks 5 are provided, and the two tracks 5 are arranged in parallel on the receiving rotating platform 2 .

[0023] Two first rail clamps 6 and two horizontal jacks 8 are provided, and the two first rail clamps 6 and the two horizontal jacks 8 are symmetrically arranged on the two rails 5. The first rail clamps 6 are adjustable on the rails 5, and the horizontal jacks 8 are detachably mounted on the first rail clamps 6. The horizontal jacks 8 can press against the upper shell 11 or the lower shell 12 of the pipe jacking machine 1 with the first rail clamps 6 as a fulcrum to push the upper shell 11 or the lower shell 12 to move horizontally along the rails 5.

[0024] Two second rail clamps 7 and two rotary jacks 9 are provided, and the two second rail clamps 7 and the two rotary jacks 9 are staggered and arranged on the two rails 5. The second rail clamps are adjustably mounted on the rails 5, and the rotary jacks 9 are detachably mounted on the second rail clamps 7. The rotary jacks 9 can press against the upper shell 11 or the lower shell 12 of the pipe jacking machine 1 with the second rail clamps 7 as a fulcrum to push the upper shell 11 or the lower shell 12 to rotate horizontally at an angle of 90 degrees.

[0025] The above structure can realize the lifting, translation and rotation operations of the pipe jacking machine 1, so as to realize the receiving and retraction of the pipe jacking machine 1. The specific operation steps are as follows: when the pipe jacking machine 1 arrives on the receiving rotating platform 2, first remove the pads and bolts of the upper shell 11 and the lower shell 12 of the pipe jacking machine 1; then lift the upper shell 11 through the vertical jack 4 to separate the upper shell 11 and the lower shell 12; then push the lower shell 12 to translate through the cooperation of the first rail clamp 6 and the horizontal jack 8. During the pushing process, when the horizontal jack 8 reaches the maximum stroke, the first rail clamp 6 is disassembled and moved to another position on the track 5 for installation, and then the horizontal jack 8 is pushed again, and this is repeated to push the lower shell 12 away from the receiving rotating platform 2; after the lower shell 12 is pushed away, the vertical jack 4 is retracted to make the upper shell 11 fall to the receiving Collect on the rotating platform 2; then, through the cooperation of the second rail clamp 7 and the rotary jack 9, push the upper shell 11 to rotate horizontally. During the rotation process, when the rotary jack 9 reaches the maximum stroke, the second rail clamp 7 is disassembled and moved to another position on the track 5 for installation, and then the rotary jack 9 is re-pushed, and this is repeated to rotate the upper shell 11 90 degrees. After the rotation, the cross-sectional size of the upper shell 11 is smaller than the cross-sectional size of the formed pipe segment, so that the upper shell 11 can retreat through the formed pipe segment. After the rotation of the upper shell 11 is completed, the first rail clamp 6 and the horizontal jack 8 are installed in reverse, pushing the upper shell 11 to translate in the opposite direction of the lower shell 12 to realize the split reception and retreat of the pipe jacking machine 1.
