[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , the sleeve mold in the pipe well in this embodiment prefabricates a combined sleeve in advance, including a mold body 1 and a sleeve body 2. A connecting component is installed on the mold body 1, and a fixing component is installed on the mold body 1.

[0024] It should be noted that an opening with the same size as the sleeve body 2 is provided inside the mold body 1, and the number of openings is several. The mold body 1 can fix the precise position and spacing of the sleeve body 2, with simple processing and a relatively small probability of error.

[0025] Embodiment 1: The connecting component includes a steel bar framework 3 fixedly installed on the top of the mold body 1. A slab surface steel bar 4 is fixedly connected inside the steel bar framework 3. Both the steel bar framework 3 and the slab surface steel bar 4 are fixedly connected to the outer side of the sleeve body 2. A fixed block 5 is fixedly installed on the top of the mold body 1, and two connecting columns 6 are fixedly installed on the top of the fixed block 5.

[0026] Among them, a mounting block 7 is fixedly installed inside the two connecting columns 6. Threaded rods 8 are threadedly connected inside both mounting blocks 7. Threaded holes are provided inside the mounting blocks 7, and threaded grooves are engraved on the outer side of the threaded rods 8. The threaded rods 8 are threadedly connected to the mounting blocks 7 through the threaded grooves and threaded holes, which is convenient for the user to rotate the threaded rods 8, so that the threaded rods 8 move out of the inside of the connecting columns 6, adjust the distance between the threaded rods 8 and the two sleeve bodies 2, and fixedly connect them to the two sleeve bodies 2, further improving the connection effect of the sleeve body 2.

[0027] In addition, extension holes are provided on the opposite sides of the two connecting columns 6. The threaded rods 8 pass through the extension holes to the outside of the connecting columns 6. Limit discs 9 are fixedly installed at the opposite ends of the two threaded rods 8. By installing the limit discs 9, it is convenient for the user to prevent the threaded rods 8 from moving out of the inside of the connecting columns 6 when rotating the threaded rods 8.

[0028] It should be noted that for the inner casing of the pipe shaft, prefabricated modular casings are used with a mold in advance. Through the installed connection components, the casing body 2 can be quickly and accurately positioned for pouring, enabling the casing body 2 to be installed on a vertical line from bottom to top, improving the construction quality and efficiency, greatly saving labor costs, and shortening the construction period.

[0029] Specifically, for the inner casing of the pipe shaft, prefabricated modular casings are used with a mold in advance. The casing body 2 to be poured is placed inside the opening in the mold body 1. Subsequently, a suitable steel bar framework 3 is fixedly welded to the mold body 1. The steel bar framework 3 is used to reinforce all the casing bodies 2 in the same area together. At the same time, manually rotate the two ejector rods 8 so that the ejector rods 8 rotate in a threaded manner inside the mounting block 7 and move out of the connecting column 6 to fix and limit the space between the two casing bodies 2, further improving the connection effect of the casing body 2, and then forming a combined device. During construction, use a laser verticality instrument to accurately position the specific position of the combined device, and then fixedly connect the slab steel bars 4 to the steel bar framework 3 that reinforces the casing body 2 to further reinforce the casing body 2 and improve the installation and fixation efficiency of the casing body 2.

[0030] Embodiment 2: Please refer to Figure 1 , on the basis of Embodiment 1, a fixing component is further installed on the mold body 1. The fixing component includes connecting blocks 10 that are slidably connected to both sides of the mold body 1, and the number of connecting blocks 10 is four.

[0031] On the opposite sides of the two groups of connecting blocks 10, sliding blocks 11 are fixedly installed. Sliding grooves are opened on both sides of the mold body 1, and the sliding blocks 11 are slidably connected to the mold body 1 through the sliding grooves, facilitating the user to move the connecting blocks 10.

[0032] Among them, bolts 12 are threadedly connected to the tops of the two groups of sliding blocks 11, positioning pins 13 are inserted into the two groups of connecting blocks 10, through holes are opened in the two groups of connecting blocks 10, and the positioning pins 13 extend to the outside of the connecting blocks 10 through the through holes.

[0033] It should be noted that for the inner casing of the pipe shaft, prefabricated modular casings are used with a mold in advance. By installing a fixing component, it is convenient to position and fix the mold body 1, making the placement of the mold body 1 more stable, improving the pouring and installation quality of the casing body 2, and improving the construction quality.

[0034] Specifically, for the inner casing of the pipe shaft, prefabricated modular casings are used with a mold in advance. During use, the connecting blocks 10 are slidably connected to the mold body 1 through the sliding blocks 11, and then the sliding blocks 11 are limited and fixed by the bolts 12. After the specific position of the combined device is accurately positioned by the laser verticality instrument, the mold body 1 is positioned and fixed by the positioning pins 13, making the placement of the mold body 1 more stable and improving the pouring and installation quality of the casing body 2.

[0035] The working principle of the above embodiments is as follows:

[0036] (1) The inner casing of the pipe shaft uses a mold to prefabricate a combined casing in advance. Place the casing body 2 to be poured inside the opening in the mold body 1. Subsequently, fix and weld a suitable steel bar framework 3 on the mold body 1. Use the steel bar framework 3 to reinforce all the casing bodies 2 in the same area together. At the same time, manually rotate the two ejector rods 8 so that the ejector rods 8 rotate in a threaded manner inside the mounting block 7 and move out of the connecting column 6 to fix and limit the space between the two casing bodies 2, further improving the connection effect of the casing body 2, and then forming a combined device. During construction, use a laser verticality instrument to accurately position the specific position of the combined device, and then fixedly connect the slab steel bars 4 with the steel bar framework 3 that reinforces the casing body 2 to further reinforce the casing body 2 and improve the installation and fixation efficiency of the casing body 2.

[0037] (2) The inner casing of the pipe shaft uses a mold to prefabricate a combined casing in advance. During use, slidably connect the connecting block 10 with the mold body 1 through the slider 11, and then limit and fix the slider 11 through the bolt 12. After accurately positioning the specific position of the combined device with a laser verticality instrument, position and fix the mold body 1 through the positioning pin 13 to make the placement of the mold body 1 more stable and improve the pouring and installation quality of the casing body 2.
