[0029] See also Figure 1 , Figure 2 and Figure 3 , showing the shield hand hole sealing device of the utility model, wherein Figure 1 The schematic diagram of the structure of one embodiment of the shield hand hole sealing device of the utility model is shown. Figure 2 Shows Figure 1 A front view of an embodiment, Figure 3 Shows Figure 1 Cross-sectional view of an embodiment.

[0030] like Figure 1 As shown, the shield handhole sealing device 10 is a triangular trapezoidal structure, which extends into the shield handhole of a triangular cross-section for sealing and filling. The shield handhole sealing device 10 includes a front bottom surface 11 and a rear bottom surface 14 abutting against the two bottom surfaces of the shield handhole, and a first side surface 12 and a second side surface 13 abutting against the two side surfaces of the shield handhole. The first side surface 12 and the second side surface 13 are located on both sides of the front bottom surface 11 and the rear bottom surface 14. A top surface 15 exposing the shield handhole is provided between the rear ends of the front bottom surface 11 and the rear bottom surface 14. At least one accommodating groove for accommodating a connector (such as a bolt head or other fixing parts, etc.) in the shield handhole is provided between the front ends of the front bottom surface 11 and the rear bottom surface 14, so that an accommodating space for the connector is provided after installation, so that the shield handhole sealing device 10 can be better filled in the shield handhole.

[0031] Among them, the shield handhole sealing device 10 is made of rubber material, preferably hard rubber. This material can provide sufficient support for the rubber wheel, increase the friction of the wheel here, reduce wheel wear, and ensure smooth rolling of the wheel.

[0032] Therefore, through the structure of the utility model, the shield hand hole can be filled, the product fits the shield hand hole, provides sufficient support when the wheel passes, and provides sufficient friction to reduce the wear of the rubber wheel and ensure smooth rolling of the wheel. The product has excellent wear resistance, pressure resistance, aging resistance, and compression permanent deformation.

As shown in the figure, the groove areas of the first groove 18, the second groove 19 and the third groove 20 gradually increase to form a step structure that is progressive in sequence. This step structure can ensure the accommodation of the shield hand hole connector. The three-stage groove can better fit the screw gasket, nut and screw head in the connector, thereby providing extremely effective support. Moreover, since support parts are formed on both sides of the first groove 18, the second groove 19 and the third groove 20, respectively, this sequential continuous support part also provides lateral support strength, so that effective support for the wheel is guaranteed when the wheel passes over. This step structure has better strength and longer service life than a single groove or depression.

These two arc transitions make the utility model consistent with the hand hole structure, easy to install, and provide effective support.

[0038] Among them, the front bottom surface 11 and the top surface 15 are connected by a first connecting surface 21 perpendicular to the front bottom surface 11, and the rear bottom surface 14 and the top surface 15 are connected by a second connecting surface 22 perpendicular to the rear bottom surface 14. The first connecting surface 21 and the second connecting surface 22 can better adapt to the structure and shape of the shield hand hole and provide a better filling effect.

[0039] like Figure 4 and Figure 5 As shown, another embodiment of the utility model is shown. In this embodiment, Figure 1The difference between the embodiment in FIG. 1 and FIG. 2 is that the front bottom surface 11 of the embodiment ， is an arc surface, Figure 1 The embodiment is a plane, wherein the front bottom surface 11 ， and the first side 12 ， and the second side 13 ， They are directly connected through an arc surface, where the size of the arc surface is R5000~R6000mm.

[0040] The top surface 15 is formed with mesh-like grooves or protrusions (or other similar structures) so as to reduce the contact area with the wheel and reduce the friction resistance.

[0041] Among them, the specific dimensions of the utility model are: 135×165×106mm or 113×164×108mm (thickness×width×height according to the front view), where the thickness is Figure 3 The horizontal dimensions, width and height are Figure 2 The horizontal and vertical dimensions of the .

[0042] It can be seen that the utility model has the following advantages:

[0043] 1. The structure fits better with the shield hand hole, providing sufficient support when the wheels pass through, reducing wheel wear and ensuring smooth wheel rolling.

[0044] 2. Made of rubber material with patterns on the surface, the friction between the wheel and the tire is greater than the friction between the concrete tunnel wall and the tire, providing better driving performance and sealing function, effectively improving service life and ensuring construction efficiency.
