[0031] Embodiment
[0032] See Figure 1 , this embodiment provides a grouting plate, which includes an upper sealing plate 1, a lower sealing plate 2, a partition plate 3 and a pressure-bearing steel pipe 4. The upper sealing plate 1 and the lower sealing plate 2 are arranged in parallel, and the partition plate 3 is arranged between the upper sealing plate 1 and the lower sealing plate 2; a plurality of partition plates 3 are provided, and the plurality of partition plates 3 are arranged at intervals and form a plurality of cavities for accommodating the pressure-bearing steel pipe 4 in combination with the upper sealing plate 1 and the lower sealing plate 2; a side sealing plate 9 is further included, the first end of the side sealing plate 9 is connected to the end of the upper sealing plate 1, and the second end of the side sealing plate 9 is connected to the end of the lower sealing plate 2.
[0033] The pressure-bearing steel pipe 4 includes a rectangular steel pipe 4.1 and a circular steel pipe 4.2. The rectangular steel pipe 4.1 is a grouting channel, and the rectangular steel pipe 4.1 is arranged in the cavity at the middle position of the grouting plate; the circular steel pipe 4.2 is a grease channel, and the circular steel pipe 4.2 is arranged in the cavities on both sides of the rectangular steel pipe, and the circular steel pipe 4.2 is preferably a seamless steel pipe.
[0034] In this embodiment, see Figure 1 , three partition plates 3 are provided, and the three partition plates 3 form four cavities for accommodating the pressure-bearing steel pipe 4 in combination with the upper sealing plate 1 and the lower sealing plate 2; there are two rectangular steel pipes 4.1 and two circular steel pipes 4.2. The two rectangular steel pipes 4.1 are arranged in the two cavities at the middle position of the grouting plate, and the two circular steel pipes 4.2 are respectively arranged in the cavities on both sides of the two cavities accommodating the rectangular steel pipes 4.1.
[0035] See Figure 2 and Figure 3, a plurality of observation holes 4.1.1 are provided along the length direction of the rectangular steel pipe 4.1. A through hole 2.1 is provided at a position on the lower sealing plate 2 corresponding to the observation hole 4.1.1. The inner diameter dimension of the observation hole 4.1.1 is smaller than the inner diameter dimension of the through hole 2.1. A cover plate 5 is provided on the observation hole 4.1.1. The cover plate 5 includes a plugging portion 5.1 and a connecting portion 5.2, and the plugging portion 5.1 is connected to the connecting portion 5.2. The outer contour dimension of the plugging portion 5.1 matches the inner diameter dimensions of the observation hole 4.1.1 and the through hole 2.1. A sealing member 6 is provided at the portion where the plugging portion 5.1 contacts the rectangular steel pipe 4.1. Since there may be a gap between the lower sealing plate 2 and the rectangular steel pipe 4.1, by setting the inner diameter dimension of the observation hole 4.1.1 to be smaller than the inner diameter dimension of the through hole 2.1 and using the cover plate 5 and the sealing member 6 in cooperation, it is possible to prevent the slurry from leaking from around the observation hole 4.1.1 during grouting.
[0036] In this embodiment, the connecting portion 5.2 of the cover plate 5 is detachably connected to the lower sealing plate 2. Preferably, bolt fastening connection is adopted, which is convenient for disassembling the cover plate 5 to check whether there is a blockage problem in the rectangular steel pipe 4.1.
[0037] See Figure 4 and Figure 5 , in this embodiment, a plurality of openings 4.2.1 are provided on the circular steel pipe 4.2. The positions of the plurality of openings 4.2.1 correspond to the cavity positions between the tail brush of the shield and the segment. A through hole 2.2 is provided at a position on the lower sealing plate 2 corresponding to the opening 4.2.1. A connecting pipe 7 is provided between the opening 4.2.1 and the through hole 2.2. The first end of the connecting pipe 7 is flush with the inner surface of the circular steel pipe 4.2 at the opening 4.2.1, and the second end of the connecting pipe 7 is flush with the outer surface of the lower sealing plate 2 at the through hole 2.2. Setting the connecting pipe can prevent the grease from flowing into the shield machine interior from the gap between the circular steel pipe and the lower sealing plate. Preferably, sealant can also be applied to the connecting parts of the connecting pipe 7 with the opening 4.2.1 and the through hole 2.2 to further prevent grease leakage. When the shield machine is tunneling, the seamless steel pipe serves as a grease passage, and the grease flows into the cavity between the tail brush of the shield and the segment through the connecting pipe 7 to prevent the slurry at the tail of the shield machine from entering the shield machine interior.
[0038] To prevent grease leakage, a plug 8 is welded to the tail of the seamless steel pipe.
[0039] In this embodiment, the assembly process of the grouting plate is as follows: Weld two side sealing plates 9 to both ends of the upper sealing plate 1 respectively, and weld the partition plates 3 to the upper sealing plate 1. The spacing distance of the partition plates 3 is determined by the dimensions of the rectangular steel pipes 4.1 and the circular steel pipes 4.2; The three partition plates 3 separate four cavities, and two rectangular steel pipes 4.1 and two circular steel pipes 4.2 are placed respectively to form two grouting channels and two grease channels. Finally, weld the lower sealing plate 2 to the two side sealing plates 9 to complete the welding and assembly of the grouting plate.
[0040] For the grouting plate provided by the utility model, the upper sealing plate 1, the lower sealing plate 2, the partition plates 3 and the side sealing plates 9 adopt a welded combination structure. The rectangular steel pipes 4.1 are used as the grouting channels, and seamless steel pipes are used as the grease channels. There are no key welds on the whole grouting plate, and no complex drilling processing technology is required, which reduces the processing difficulty of the grouting plate, shortens the processing cycle, and thus reduces the manufacturing cost.
[0041] This embodiment provides a shield machine, which includes the grouting plate as described above. The grouting plate is arranged in the shield tail shell and is used for grouting the gap between the tunnel and the segment, and providing grease for the cavity between the shield tail brush and the segment; The grouting plate adopts rectangular steel pipes 4.1 and seamless steel pipes, which can effectively prevent the leakage of slurry or grease during the construction process and improve the construction safety.
[0042] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. For those skilled in the art, the utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
