Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
The first embodiment is as follows: the TBM pressure casting type concrete test device comprises a shield body and a grouting head which is arranged in the shield body and used for pressure casting concrete, wherein an annular space between the shield body and the grouting head needs to be sealed.
As shown in the attached drawings 1-4, the TBM pressure injection type concrete test device sealing assembly arranged in the TBM pressure injection type concrete test device and used for realizing sealing between an imitation shield body and a grouting head comprises a plurality of pressing plates 1, a plurality of lip-shaped sealing press rings 2 and a plurality of fastening components. The platen 1 and the lip seal ring 2 are alternately stacked to form a stacked structure. Typically, the number of pressure plates 1 is 1 greater than the number of lip-sealing pressure rings 2, so that both ends of the laminated structure are formed by the pressure plates 1. In this embodiment, 3 pressure plates 1 and 2 lip-shaped sealing rings 2 are provided, each of which has a circular ring shape, and the axial direction of the laminated structure formed after lamination is the left-right direction in fig. 2, and based on this, two axial ends of the laminated structure are defined as the inner end and the outer end, respectively, so that the inner end corresponds to the left end in fig. 2 and the outer end corresponds to the right end in fig. 2. The outer end of the pressure plate 1 is thicker than the other two pressure plates 1.
The laminated structure formed by the pressure plate 1 and the lip-shaped sealing press ring 2 is fixedly connected through a fastening assembly. The fastening components are uniformly distributed on the laminated structure in an annular mode, and each layer of the laminated structure comprises each pressing plate 1 and each lip-shaped sealing pressing ring 2 which are correspondingly provided with fastening holes matched with the fastening components. The fastening component comprises a compression screw rod 3 and a nut 4 matched with the compression screw rod 3, and can also comprise a seamless steel pipe 5 which is sleeved on the compression screw rod 3 and is pressed on the side part of the pressing plate 1 positioned at the inner end of the laminated structure by the nut 4. An annular groove 6 for accommodating the screw head of the compression screw 3 is formed in the pressure plate 1 at the outer end of the laminated structure. Therefore, the compression screw 3 sequentially penetrates through each layer of the laminated structure and the corresponding steel pipe 5 from the pressing plate 1 at the right end, and is finally compressed layer by the nut 4. A rubber sealing gasket can be arranged between the screw head of the compression screw 3 and the bottom of the groove 6 of the outer end pressing plate 1.
In the above scheme, the pressing plate 1 can be formed by splicing a plurality of (such as 12) same pressing plate 1 units, and each pressing plate 1 unit is arc-shaped.
The sealing assembly of the TBM pressure injection type concrete test device is particularly important for realizing the sealing of the TBM pressure injection type concrete test device, the problem of large eccentricity of the installation position is solved through lip sealing, and the lip structure has good follow-up property and is suitable for occasions with large eccentricity. It is one-way sealed, can seal the muddy water of its outer end. And the device can be quickly disassembled and assembled, and has lower requirements on structure manufacturing and structure form.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
