Description

Technical Field

[0001] This utility model relates to the field of shield tunnel portal construction, and in particular to a tie-in device for a split-type portal water-stop flap. Background Technology

[0002] Currently, during shield tunnel construction, the shield launching at the tunnel portal typically employs a water-stopping device consisting of a water-stopping flap and a water-stopping curtain, with the water-stopping flap located on the side of the water-stopping curtain furthest from the tunnel portal.

[0003] Traditional water-stop flaps are integral flaps with multiple mounting holes on the top horizontally. A portal steel ring is located on the side of the tunnel entrance, with threaded holes corresponding to the mounting holes. The water-stop curtain has mating holes corresponding to the mounting holes. Bolts pass through the threaded holes, mating holes, and mounting holes simultaneously. During the installation of the water-stop flap, the misalignment of the bolt holes on the portal steel ring makes the overall installation of the flap difficult. Therefore, split-type water-stop flaps have appeared on the market, which are spliced ​​together from multiple narrower unit flaps. Each unit flap includes an installation part fixed to the portal steel ring and a water-stop part rotatably connected to the installation part. When the tunnel boring machine enters the tunnel entrance, the water-stop part is pushed and squeezed by the tunnel boring machine, thus forming a water-stop structure.

[0004] The aforementioned split-type water-stop flaps are prone to uneven stress on the overall water-stop flaps due to their separate installation. The structural stability and sealing reliability of the overall water-stop flaps need to be improved, and the water-stopping effect of the overall water-stop structure needs to be improved.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a tie-in device for a split-type portal water-stop flap.

[0029] Reference Figure 1-5The tying device of the split-type portal water-stop flap includes a clamping channel steel 1, a tying bolt 2, a tying nut 3, and a connecting component 4. The clamping channel steel 1 is set on the mounting part 91, which has a locking hole 912 and a locking hole 913. The bolt of the tying bolt 2 passes through the locking hole 912 and the locking hole 913. The tying nut 3 is threadedly connected to the tying bolt 2. An annular abutment washer 12 is provided between the tying nut 3 and the clamping channel steel 1. The bolt of the tying bolt 2 passes through the abutment washer 12. The clamping channel steel 1 is a C-shaped steel with its opening facing away from the mounting part 91. An annular clamping washer 13 is installed inside the clamping channel steel 1. Multiple clamping washers 13 are arranged, and these washers 13 abut against each other and against the inner wall of the clamping channel steel 1. The thread of the tie bolt 2 passes through the clamping washer 13. The clamping washer 12, in conjunction with the clamping washer 13, improves the connection performance of the tie bolt 2 and the tie nut 3 between the clamping channel steel 1 and the mounting part 91.

[0030] The mounting portions 91 of multiple consecutive unit flaps 9 are fixed by the same clamping channel steel 1. In this embodiment, a water-stop flap includes two unit flaps 9, and the mounting portions 91 of the two unit flaps 9 are fixed by the same clamping channel steel 1.

[0031] Locking hole 2 913 is oblong, which makes it easy to accommodate the offset of mounting hole 911 on mounting part 91.

[0032] Two adjacent clamping channel steels 1 are connected and fixed together by a connecting assembly 4. The connecting assembly 4 includes a connecting plate 41, a connecting bolt 42, and a connecting nut 43. Both ends of the connecting plate 41 extend into the two adjacent clamping channel steels 1. The mounting part 91 has a first connecting hole 914, the clamping channel steel 1 has a second connecting hole 11, and the connecting plate 41 has a third connecting hole 411. The thread of the connecting bolt 42 passes through the first connecting hole 914, the second connecting hole 11, and the third connecting hole 411. The connecting nut 43 is threaded onto the connecting bolt 42. An annular clamping washer 3 14 is provided between the connecting nut 43 and the clamping channel steel 1, and the thread of the connecting bolt 42 passes through the clamping washer 3 14. The clamping washer 3 14 improves the locking performance of the connecting bolt 42 and the connecting nut 43 on the clamping channel steel 1, the mounting part 91, and the connecting plate 41.

[0033] Both connecting hole 2 11 and connecting hole 3 411 are oblong holes, which facilitates the offset of connecting hole 1 914 on the mounting part 91.

[0034] By installing and fixing the clamping channel steel 1, the tie bolts 2 and the tie nuts 3, the overall strength of the multiple unit flaps 9 is improved to form a water-stop flap. Then, by connecting the two adjacent clamping channel steels 1 through the connecting component 4, the overall structural stability and sealing reliability of all water-stop flaps are improved, the overall stress performance of the split water-stop flap is enhanced, and the water-stopping effect of the overall water-stopping structure is improved.

[0035] The mounting part 91 is also provided with a limiting plate 5. One end of the limiting plate 5 is fixedly connected to the mounting part 91 through the fixing component 6, and the other end of the limiting plate 5 abuts against the water-stopping part 92. The fixing component 6 includes a fixing bolt 61 and a fixing nut 62. The limiting plate 5 is provided with a limiting hole 51 that aligns with the mounting hole 911 of the mounting part 91. The screw of the fixing bolt 61 passes through the threaded hole 71 of the portal steel ring 7, the mating hole 81 of the water-stopping curtain 8, the mounting hole 911 of the mounting part 91, and the limiting hole 51 of the limiting plate 5. The fixing nut 62 is threadedly connected to the fixing bolt 61.

[0036] An annular clamping washer 621 is provided between the fixing nut 62 and the limiting plate 5, and the screw of the fixing bolt 61 passes through the clamping washer 621. The clamping washer 621 improves the locking performance of the fixing bolt 61 and the fixing nut 62 on the limiting plate 5, the mounting part 91, the water-stop curtain 8 and the portal steel ring 7.

[0037] The setting of the limiting plate 5 prevents the water-stopping part 92 from tilting away from the water-stopping curtain 8, thereby improving the water-stopping effect.

[0038] The implementation principle of the tie-up device for a split-type portal water-stop flap in this application embodiment is as follows:

[0039] First, connect the unit flap 9 to the water-stop curtain 8 and the portal steel ring 7. When connecting, pass the screw of the fixing bolt 61 through the threaded hole 71 of the portal steel ring 7, the mating hole 81 of the water-stop curtain 8, the mounting hole 911 of the mounting part 91 and the limiting hole 51 of the limiting plate 5. Then, place the four abutting washers 621 on the fixing bolt 61 and then thread the fixing nut 62 onto the fixing bolt 61 so that the fixing nut 62 and the four abutting washers 621 are pressed together.

[0040] Then, press the clamping channel steel 1 onto the mounting part 91 of the two unit flaps 9, then pass the screw of the tie bolt 2 through the locking hole 1 912, the abutment washer 2 13 and the locking hole 2 913, then place the abutment washer 12 on the tie bolt 2, and then thread the tie nut 3 onto the tie bolt 2, so that the tie nut 3 and the abutment washer 12 are pressed together, so that the multiple unit flaps 9 of a water-stop flap are connected and fixed to form a water-stop flap.

[0041] Finally, insert both ends of the connecting plate 41 into the two adjacent clamping channel steels 1, then pass the screw of the connecting bolt 42 through the connecting hole 914, the connecting hole 11, and the connecting hole 411. Then place the clamping washer 314 on the connecting bolt 42, and then thread the connecting nut 43 onto the connecting bolt 42, so that the connecting nut 43 and the clamping washer 314 are pressed together, so that all the clamping channel steels 1 are connected and fixed, thereby fixing all the water-stop flaps.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
