Specifically, the plane where the bending section 3 is located is perpendicular to the plane where the connecting strip 2 is located, and the bending section 3 is located on the bottom wall of the connecting strip 2; in other embodiments, the plane where the bending section 3 is located and the plane where the connecting strip 2 is located can also be greater than 90 degrees and less than 180 degrees.

[0022] Reference Figure 1 and Figure 2 A connecting groove 4 is provided on the side of the preform 1 away from the corresponding connecting strip 2. The connecting groove 4 corresponds to the connecting strip 2 one by one. The width of the opening of the connecting groove 4 is adapted to the distance from the upper surface of the connecting strip 2 to the lower surface of the bending section 3. The connecting groove 4 is used for the corresponding connecting strip 2 and the bending section 3 of the adjacent preform 1 to move in or out. A groove 5 is provided on the lower inner wall of the connecting groove 4. The groove 5 is used to engage with the bending section 3 of the adjacent preform 1. When the bending section 3 abuts against the bottom wall of the connecting groove 4 of the adjacent preform 1, the bending section 3 on the connecting strip 2 is aligned with the corresponding groove 5; when the bending section 3 is engaged with the groove 5 on the adjacent preform 1, the corresponding adjacent preforms 1 abut and align.

[0023] Reference Figure 2 A mounting groove 20 is provided on the bottom wall of the connecting groove 4, and the mounting groove 20 is located above the corresponding groove 5. An abutment plate 6 is slidably penetrated in the mounting groove 20, and the sliding direction of the abutment plate 6 is parallel to the arrangement direction of the plurality of preforms 1. The abutment plate 6 is used to abut against the side of the connecting strip 2 away from the bending section 3.

[0024] When assembling and splicing the prefabricated parts 1, align the connecting strip 2 and the bending section 3 of the prefabricated part 1 with the connecting groove 4 of the adjacent prefabricated part 1, move the prefabricated part 1 where the connecting strip 2 is located in the direction close to the connecting groove 4, and at the same time, adjust the abutment plate 6 by the adjustment mechanism to move it in the installation groove 20 in the direction away from the groove 5 until the bending section 3 abuts against the bottom wall of the connecting groove 4. At this time, the bending section 3 on the connecting strip 2 is aligned with the groove 5, and then move the prefabricated part 1 where the bending section 3 is located in the direction close to the groove 5, so that the bending section 3 is clamped with the groove 5 of the adjacent prefabricated part 1. The connecting strip 2 is fitted into the groove 5, so that the side wall of the connecting strip 2 is separated from the corresponding abutment plate 6. The abutment plate 6 is adjusted by the adjustment mechanism to move toward the direction close to the groove 5, so that the abutment plate 6 abuts against the side of the connecting strip 2 away from the bending section 3, thereby realizing the alignment and fixation of two adjacent prefabricated parts 1 without repeated calibration and alignment, which helps to improve the overall construction efficiency of the tunnel; at the same time, through the clamping of the bending section 3 and the groove 5 and the limitation of the connecting strip 2 by the abutment plate 6, it is difficult for adjacent prefabricated parts 1 to slide left and right or up and down, which helps to improve the overall structural stability of the tunnel.

Arranging two connecting strips 2 relatively helps to improve the connection strength and stability between adjacent preforms 1.

[0026] Reference Figure 2 and Figure 3 In order to facilitate the adjustment of the abutment plate 6 to slide in a direction close to or away from the groove 5, the adjustment mechanism includes an adjustment spring 7 and a pulling assembly. The adjustment spring 7 is located in the mounting groove 20. The extension direction of the adjustment spring 7 is parallel to the sliding direction of the abutment plate 6. One end of the adjustment spring 7 is fixed on the corresponding abutment plate 6, and the other end is fixed on the bottom wall of the corresponding mounting groove 20. The adjustment spring 7 is used to push the corresponding abutment plate 6 to slide in a direction close to the groove 5 to abut against the side wall of the adjacent preform 1. The pulling assembly is arranged in the preform 1, and the pulling assembly is used to pull the abutment plate 6 to slide in a direction away from the groove 5.

[0027] Reference Figure 2 and Figure 3In order to facilitate the sliding of the abutment plate 6 in the direction away from the groove 5, a sliding cavity 15 is provided in the preform 1, and the sliding cavity 15 corresponds to the abutment plate 6 one by one. The sliding cavity 15 is located above the corresponding abutment plate 6 and is located on the side of the mounting groove 20 in the preform 1 close to its own connecting strip 2. The pulling component includes a sliding block 8 and a transmission member. The sliding block 8 corresponds to the abutment plate 6 one by one. The sliding block 8 is slidably arranged in the corresponding sliding cavity 15. The sliding direction of the sliding block 8 is perpendicular to the splicing direction of the plurality of preforms 1. Specifically, the sliding block 8 slides in the vertical direction; the transmission member is arranged on the sliding block 8, and the transmission member is used to pull the abutment plate 6 to slide in the direction away from the groove 5 when the sliding block 8 slides in the direction away from the corresponding abutment plate 6. An adsorption member for driving the sliding block 8 to move is provided on the sliding block 8 located above the pipeline in the preform 1, and a connecting member for making the two sliding blocks 8 move synchronously is provided between the two sliding blocks 8 of the preform 1.

[0028] Reference Figure 2 and Figure 3 In order to facilitate the sliding block 8 to slide in the direction away from the corresponding abutment plate 6 and pull the abutment plate 6 to slide in the direction away from the groove 5, an installation cavity 21 is opened in the preform 1, the installation cavity 21 corresponds to the abutment plate 6 one by one, and the installation cavity 21 is located below the corresponding sliding cavity 15, and the installation cavity 21 is located on the side of the corresponding installation groove 20 close to the connecting strip 2, and the transmission member includes a roller 9, a first drum 10, a first pull rope 11, a second drum 12 and a second pull rope 13, the roller 9 corresponds to the abutment plate 6 one by one, and the roller 9 is rotatably arranged in the corresponding installation cavity 21, and the rotation axis of the roller 9 is perpendicular to the plurality of preforms 1 Arrangement direction, specifically, the rotation axis of the roller 9 is arranged in the horizontal direction; the first drum 10 is fixedly sleeved on the roller 9, one end of the first pull rope 11 is wound on the first drum 10, and the other end slides through the preform 1 to extend into the sliding cavity 15 and connects to the bottom wall of the corresponding sliding block; the second drum 12 is fixedly sleeved on the roller 9, one end of the second pull rope 13 is wound on the second drum 12, and the other end slides through the preform 1 to extend into the installation groove 20 and is fixed to the side of the abutment plate 6 away from the groove 5; the first pull rope 11 and the second pull rope 13 are wound in opposite directions, and the diameter of the first drum 10 is smaller than the diameter of the second drum 12. When the sliding block 8 abuts against the bottom wall of the corresponding sliding cavity 15, the first pull rope 11 and the second pull rope 13 are both in tension, and the side of the abutment plate 6 away from the adjustment spring 7 is flush with the outer wall of the corresponding side of the preform 1.

[0029] Reference Figure 2 and Figure 3In order to facilitate the movement of the sliding block 8, the adsorption member includes a magnet 14, which is fixed on the top wall of the sliding block 8 located above the inner pipeline of the preform 1. The magnet 14 is used to be adsorbed and connected with the external magnetic block. The adsorption force between the magnet 14 and the external magnetic block is greater than the sum of the elastic forces of the upper and lower adjustment springs 7. The sliding cavity 15 located above the inner pipeline of the preform 1 passes through the upper end of the preform 1. A non-magnetic material layer 16 is fixed in the sliding cavity 15 located above the inner pipeline of the preform 1. The non-magnetic material layer 16 seals the sliding cavity 15. The non-magnetic material layer 16 can be one of a plastic plate, a glass sheet, etc. A protective plate 17 is detachably provided in the sliding cavity 15 located above the inner pipeline of the preform 1 by means of screws, bolts, etc. The protective plate 17 is located on the side of the non-magnetic material layer 16 away from the sliding block 8, and the protective plate 17 and the preform 1 are sealed, which can effectively protect the non-magnetic material layer 16.

[0030] Reference Figure 2 and Figure 3 In order to facilitate the synchronous movement of the sliding blocks 8 on the upper and lower sides of the preform 1, the connecting member includes a connecting rope 18 arranged between the two sliding blocks 8 in the preform 1. The connecting rope 18 slides through the preform 1 and extends into the sliding cavities 15 on the upper and lower sides respectively. When the upper and lower sliding blocks 8 are in contact with the bottom walls of the corresponding sliding cavities 15, the connecting rope 18 is in a tensioned state. The connecting rope 18 is located on the side of the pipeline mounting frame in the preform 1, which helps to protect the pipeline on the mounting frame to ensure that the pipeline is not easy to fall from the mounting frame.

[0031] When the preform 1 is in the initial state, the abutment plate 6 extends out of the corresponding installation groove 20 to the connecting groove 4 under the thrust of the adjusting spring 7, and the side of the abutment plate 6 away from the adjusting spring 7 is flush with the outer wall of the corresponding side of the preform 1; during the movement of the abutment plate 6 in the direction away from the adjusting spring 7, the second pull rope 13 will be pulled, and the second pull rope 13 will pull the second reel 12 to drive the roller 9 to rotate, so that the roller 9 drives the first reel 10 to rotate and reel up the first pull rope 11, so that the sliding block 8 abuts against the bottom wall of the corresponding sliding cavity 15.

[0032] When assembling the prefabricated parts 1, align the connecting strip 2 of the prefabricated part 1 with the connecting groove 4 of the adjacent prefabricated part 1, and move the prefabricated part 1 where the connecting strip 2 is located in the direction close to the connecting groove 4. At this time, the connecting strip 2 will abut against the abutment plate 6 of the adjacent prefabricated part 1, and push the abutment plate 6 to move into the installation groove 20 in the direction away from the groove 5, compress the adjustment spring 7, until the bending section 3 abuts against the bottom wall of the connecting groove 4. At this time, the bending section 3 on the connecting strip 2 is aligned with the groove 5, and then move the prefabricated part 1 where the bending section 3 is located in the direction close to the groove 5, and align the bending section 3 with the groove 5 of the adjacent prefabricated part 1. The snap-fitting makes the connecting strip 2 disengage from the side of the abutment plate 6, and then the compressed adjusting spring 7 pushes the abutment plate 6 to move in the direction close to the groove 5, so that the abutment plate 6 abuts against the side of the connecting strip 2 away from the bending section 3. At this time, the abutment plate 6 and the connecting strip 2 fill the connecting groove 4, thereby realizing the alignment and fixation of two adjacent prefabricated parts 1, without the need for repeated calibration and alignment, which helps to improve the overall construction efficiency of the tunnel; at the same time, through the snap-fitting of the bending section 3 and the groove 5 and the limiting of the connecting strip 2 by the abutment plate 6, the overall structure of the tunnel can be ensured not to be easily loosened by vibration during long-term use.

[0033] When the pipe gallery is aged, or the design of the pipe gallery needs to be changed or new pipelines are added due to urban development, the pipe gallery needs to be disassembled, and the protection plate 17 is removed from the top of the prefabricated part 1 to expose the non-magnetic material layer 16. Then, an external magnetic block is used to absorb the magnet 14 on the sliding block 8 across the non-magnetic material layer 16, so that the magnet 14 drives the sliding block 8 to move upward, and the sliding block 8 pulls the sliding block 8 located below to move synchronously through the connecting rope 18, so that the two sliding blocks 8 pull the corresponding first pull rope 11, and the first pull rope 11 pulls the corresponding first reel 10 and the roller 9 to rotate, so that the roller 9 drives the second reel 12 to rotate and reel the second pull rope 13, so that the second pull rope 13 pulls the abutment plate 6 to slide in the direction close to the installation groove 20, so that the abutment plate 6 is separated from the corresponding connecting strip 2, and then the prefabricated part 1 where the connecting strip 2 is located is moved upward to separate the bending section 3 from the groove 5, and then the prefabricated part 1 is moved in the direction away from the connecting groove 4 of the adjacent prefabricated part 1, so that the adjacent prefabricated parts 1 can be separated, which is simple and convenient.

[0034] Reference Figure 2 and Figure 3 A sealing gasket 19 is fixed on the side of the abutment plate 6 away from the adjustment spring 7. The sealing gasket 19 is used to abut against the end surface of the adjacent prefabricated member 1. The provision of the sealing gasket 19 helps to improve the sealing between the adjacent prefabricated members 1. Sealing layers (not shown in the figure) are fixed on both upper and lower sides of both ends of the prefabricated member 1. The connecting groove 4 or the connecting strip 2 at each end is located between the two sealing layers at the corresponding end. The sealing layers between the adjacent prefabricated members 1 abut against each other to improve the waterproof performance of the pipe gallery.

[0035] The implementation principle of the BIM-based prefabricated underground integrated pipeline corridor in the embodiment of the present application is: when the prefabricated component 1 is in the initial state, the abutment plate 6 extends out of the corresponding installation groove 20 under the thrust of the adjusting spring 7 and extends into the connecting groove 4, and the side of the abutment plate 6 away from the adjusting spring 7 is flush with the outer wall of the corresponding side of the prefabricated component 1. At this time, the sliding block 8 abuts against the bottom wall of the corresponding sliding cavity 15.

[0036] When assembling the prefabricated parts 1, align the connecting strip 2 of the prefabricated part 1 with the connecting groove 4 of the adjacent prefabricated part 1, and move the prefabricated part 1 where the connecting strip 2 is located in the direction close to the connecting groove 4. At this time, the connecting strip 2 will abut against the abutment plate 6 of the adjacent prefabricated part 1, and push the abutment plate 6 to move in the direction away from the groove 5 until the bending section 3 abuts against the bottom wall of the connecting groove 4. At this time, the bending section 3 on the connecting strip 2 is aligned with the groove 5, and then move the prefabricated part 1 where the bending section 3 is located in the direction close to the groove 5, so that the bending section 3 is aligned with the groove of the adjacent prefabricated part 1. 5 is engaged and matched, so that the side of the connecting strip 2 and the abutment plate 6 are separated, and then the compressed adjustment spring 7 pushes the abutment plate 6 to move in the direction close to the groove 5, so that the abutment plate 6 abuts against the side of the connecting strip 2 away from the bending section 3, thereby realizing the alignment and fixation of two adjacent prefabricated parts 1, without the need for repeated calibration and alignment, which helps to improve the overall construction efficiency of the pipe gallery; at the same time, through the engagement of the bending section 3 with the groove 5 and the limitation of the connecting strip 2 by the abutment plate 6, it helps to ensure that the overall structure of the pipe gallery is not easily loosened due to vibration during long-term use.

[0037] The present application also discloses a construction method of the above-mentioned BIM-based prefabricated underground comprehensive pipe gallery. The BIM-based prefabricated underground comprehensive pipe gallery construction method comprises the following steps: Step 1: Conduct data survey on the underground and surface of the construction site to obtain underground and surface data; Step 2: Building a BIM 3D model based on the 3D model of the prefabricated component 1 and the underground and surface survey data; Step 3: According to the BIM three-dimensional model, the actual size, overall structure and number of prefabricated parts 1 required are worked out; Step 4: Produce the prefabricated component 1 and transport it to the construction site; Step 5: Splice and fix multiple prefabricated parts 1 to each other at the construction site, wherein the connecting strip 2 of the prefabricated part 1 is aligned with the connecting groove 4 of the adjacent prefabricated part 1, and the prefabricated part 1 where the connecting strip 2 is located is moved in the direction close to the connecting groove 4, and the connecting strip 2 abuts the abutment plate 6 in the adjacent prefabricated part 1, driving the abutment plate 6 to move in the direction away from the groove 5 until the bending section 3 is aligned with the groove 5, and then the prefabricated part 1 where the bending section 3 is located is moved in the direction close to the groove 5, and the bending section 3 is engaged with the groove 5 of the adjacent prefabricated part 1, so that the side wall of the connecting strip 2 and the abutment plate 6 is disengaged, and the abutment plate 6 is moved in the direction close to the groove 5 under the push of the adjusting spring 7, so that the abutment plate 6 abuts against the side of the connecting strip 2 away from the bending section 3, and the sealing gasket 19 abuts against the end face of the adjacent prefabricated part 1; then concrete is sealed at the joint of the two prefabricated parts 1 to fix the two prefabricated parts 1, and then the above operation is repeated to complete the connection of multiple prefabricated parts 1.
