Technical Field

[0002] During the construction of the vertical shaft connecting passages, the existing secondary lining trolleys cannot adequately adapt to various cross-sectional dimensions due to the large number of passages and significant variations in cross-sectional dimensions. Furthermore, the formwork support system requires lengthy setup and dismantling processes and is prone to formwork slippage and grout leakage. This results in low construction efficiency and difficulty in ensuring construction quality. Summary of the Invention
[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a secondary lining support device for vertical shaft connecting passages that can adapt to various cross-sections of different sizes, has high construction efficiency, and ensures construction quality.
[0004] This utility model discloses a secondary lining support device for a vertical shaft connecting passage, comprising a horizontal beam A, a horizontal beam B, a longitudinal connecting beam A, a longitudinal connecting beam B, a horizontal brace A, a longitudinal distribution beam A, a side brace A, a longitudinal distribution beam B, a longitudinal distribution beam C, a side brace B, a longitudinal distribution beam D, a circumferential distribution beam, an I-beam column, a longitudinal connecting beam C, a longitudinal distribution beam E, a connecting plate, and end braces. The circumferential distribution beam contains the horizontal beam A, the longitudinal distribution beam A, the longitudinal distribution beam B, the longitudinal distribution beam C, and the longitudinal distribution beam D. Beam D, longitudinal distribution beam E, and connecting plate. Connecting steel bars are installed on the connecting plate. I-beam columns are connected to horizontal beam A, horizontal beam B, longitudinal connecting beam A, longitudinal connecting beam B, horizontal brace A, longitudinal connecting beam C, and longitudinal distribution beam E respectively. Horizontal beam B is connected to longitudinal distribution beam C. Horizontal brace A is connected to longitudinal distribution beam A. Side brace A is connected to horizontal brace A and longitudinal distribution beam B respectively. One end of side brace B is connected to longitudinal distribution beam D, the middle is connected to horizontal beam B, and the other end is connected to horizontal brace A. The end brace abuts against the circumferential distribution beam.
[0005] The circumferential distribution beam consists of several beams, each composed of an arc-shaped beam at the top and a vertical support beam. The arc-shaped beam is connected to the support beam by bolts.
[0006] The connecting plate is equipped with connecting steel bars.
[0007] The end bracing consists of several sections, which abut against the ground anchor steel bars.
[0008] Compared with the prior art, this utility model has significant advantages. As can be seen from the above technical solution: A horizontal beam A, a longitudinal distribution beam A, a longitudinal distribution beam B, a longitudinal distribution beam C, a longitudinal distribution beam D, a longitudinal distribution beam E, and a connecting plate are installed within the circumferential distribution beam. Connecting reinforcing bars are installed on the connecting plate. I-beam columns connect the horizontal beam A, horizontal beam B, longitudinal connecting beam A, longitudinal connecting beam B, horizontal brace A, longitudinal connecting beam C, and longitudinal distribution beam E. Horizontal beam B connects to longitudinal distribution beam C. Horizontal brace A connects to longitudinal distribution beam A. Side brace A connects to horizontal brace A and longitudinal distribution beam B. One end of side brace B connects to longitudinal distribution beam D, the middle connects to horizontal beam B, and the other end connects to horizontal brace A. The end brace abuts against the circumferential distribution beam. The I-beam connections of the circumferential distribution beam are filled and welded shut with steel plates; it is strictly forbidden for the I-beam connections of the circumferential distribution beam to become detached. The I-beams of the circumferential distribution beams are connected by bolts through connecting plates, facilitating disassembly and allowing for quick adjustment and assembly according to different construction needs, thus greatly improving construction flexibility and efficiency. At the connection between the end diagonal braces and the ground, ground anchor steel bars are used for limiting, with the anchor steel bars embedded at least 30cm into the ground. Any gaps are secured with wooden wedges. The end formwork of the straight wall section is fixed with I-beams as side diagonal braces, while the curved section of the circumferential distribution beam is fixed using pre-embedded steel bars and steel bars inserted into the stone body. The wooden planks of the operating platform are securely tied. When the cross-sectional dimensions are different, only the curvature of the circumferential distribution beam 13 and the height of the support beam 21 need to be appropriately modified to adapt to different cross-sectional dimensions in the connecting passage, stably supporting the secondary lining and ensuring construction quality. This utility model also has a significant price advantage; compared to traditional lining trolleys, it is lower in cost and more economical. In summary, this utility model can adapt to various cross-sectional dimensions, has high construction efficiency, and guarantees construction quality. Attached Figure Description

[0017] The purpose of this utility model and the solution to its main technical problem are achieved by the following technical solution:
[0018] This utility model discloses a secondary lining support device for a vertical shaft connecting passage, comprising connecting steel bars 1, horizontal beams A2 and B3, longitudinal connecting beams A4 and B5, horizontal bracing A6, longitudinal distribution beams A7, lateral bracing A8, longitudinal distribution beams B9 and C10, lateral bracing B11, longitudinal distribution beams D12, circumferential distribution beams 13, I-beam columns 14, longitudinal connecting beams C15 and E16, connecting plates 17, and end bracing 18. The circumferential distribution beams 13 are respectively equipped with horizontal beams A2, longitudinal distribution beams A7, B9, C10, D12, and E16, and connecting plates 17. Connecting steel bars 1 are installed on the connecting plates 17, and the I-beam columns 14 are respectively connected to water... A horizontal beam A2, a horizontal beam B3, a longitudinal connecting beam A4, a longitudinal connecting beam B5, a horizontal brace A6, a longitudinal connecting beam C15, and a longitudinal distribution beam E16 are included. Horizontal beam B3 connects to longitudinal distribution beam C10, horizontal brace A6 connects to longitudinal distribution beam A7, and side brace A8 connects to horizontal brace A6 and longitudinal distribution beam B9 respectively. Side brace B11 connects to longitudinal distribution beam D12 at one end, horizontal beam B3 in the middle, and horizontal brace A6 at the other end. End brace 18 abuts against circumferential distribution beam 13. There are several circumferential distribution beams 13, which are composed of an arc-shaped beam 20 with an arc-shaped upper end and a vertical support beam 21. The arc-shaped beam 20 is connected to the support 21 by bolts. Connecting steel bars 1 are installed on the connecting plate 17. There are several end braces 18, and the end braces 18 abut against ground anchor steel bars 19.
[0019] When using; see; Figure 1At the connection between the end diagonal brace 18 and the ground, ground anchor steel bars 19 must be used for limiting treatment. The ground anchor steel bars 19 must be anchored into the ground to a depth of not less than 30cm. Any gaps should be firmly wedged with wooden wedges. Thick wooden boards should be laid all over the outside of the circumferential distribution beam 13 I-beam. Thick wooden boards should also be laid on the horizontal beam A2 as a personal stepping platform. The two end diagonal braces 18 should be placed against the two ends of the circumferential distribution beam 13 respectively, and then concrete can be poured.
