[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-4The utility model provides a shield segment with pre -buried channel structure, including segment body 1, is seted up with sealing strip groove 4 on segment body 1, is seted up with opening 2 on segment body 1, and the other end of segment body 1 is fixedly set up with pre -buried frame 51, and the inner wall of pre -buried frame 51 is fixedly installed with limit rail 52, and the sliding installation of limit rail 52 has adjusted block 54, and the inclined setting of screw groove 57 is seted up on adjusted block 54;

[0022] The segment body 1 is provided with a screw hole 3 in communication with the opening 2;

[0023] Wherein reference Figure 2 When two segments are connected together, the screw hole 3 of the left segment cooperates with the screw groove 57 of the right segment, and in the actual installation process, due to errors and other factors, the screw hole 3 and the screw groove 57 are often difficult to align, and there is a partial misalignment, so in the installation process, the screw rod is inserted into the screw hole 3, and then hammered to be inserted into the screw groove 57, and at this time, the violent entry of the screw rod can damage the segment and cause the segment to burst, so when the screw hole 3 and the screw groove 57 are not completely aligned due to errors and other factors, a smaller rod can be inserted into the screw hole 3 and in contact with the adjusted block 54, the position of the adjusted block 54 can be slidably adjusted, so that the screw groove 57 on the adjusted block 54 and the screw hole 3 are aligned, and the angles of the screw groove 57 and the screw hole 3 are consistent, so that the screw rod can be easily inserted into the screw hole 3 and the screw groove 57 to connect the two segments.

[0024] In another embodiment of the utility model: the pressure block 55 is slidably installed in the screw groove 57;

[0025] When the screw rod is inserted into the screw groove 57, the screw rod is tightened, and as the screw rod moves in the screw groove 57, it will press the pressure block 55, so that the pressure block 55 moves downward until the pressure block 55 abuts against the pre-buried frame 51, and the movement between the adjusted block 54 and the pre-buried frame 51 is limited, so as to avoid the movement of the adjusted block 54.

[0026] In another embodiment of the utility model: the pre-buried frame 51 is provided with an extrusion groove 53;

[0027] The extrusion groove 53 is provided with a bevel, and the bevel is opposite to the pressure block 55, so that when the pressure block 55 slides downward from the screw groove 57, the flat end of the pressure block 55 is completely pressed on the bevel to increase the friction.

[0028] In another embodiment of the utility model: the bottom end of the pressure block 55 is fixedly installed with a rubber pad 56;

[0029] The friction between the pressing block 55 and the extrusion groove 53 is increased by the rubber pad 56, thereby preventing the adjustment block 54 from moving. At the same time, the rubber pad 56 will be compressed to a certain extent when being squeezed, thereby exerting a reaction force on the pressing block 55 and the screw, thereby increasing the pressure between the screw and the screw groove 57, thereby playing an anti-loosening role.

[0030] In another embodiment of the present invention: the cross section of the limiting rail 52 is T-shaped, and a gap is provided between one end of the limiting rail 52 and the inner side wall of the embedded frame 51;

[0031] The adjustment block 54 is provided with a limiting groove that matches the size of the limiting rail 52. The limiting rail 52 and the limiting groove facilitate the movement of the adjustment block 54. At the same time, the gap makes it easy to install the adjustment block 54 on the limiting rail 52.

[0032] In another embodiment of the present invention, a pre-buried pipeline channel 61 is fixedly provided inside the segment body 1. The pre-buried pipeline channel 61 is bent. A connecting plate 62 is provided at the end of the pre-buried pipeline channel 61. A connecting piece 63 is fixedly installed on the connecting plate 62. A connecting groove 64 is formed on both the connecting plate 62 and the pre-buried pipeline channel 61.

[0033] The connecting groove 64 can be used to install screws to connect the connecting plate 62 and the embedded pipeline channel 61;

[0034] A wire hole is provided in the connecting piece 63, so that the cable can pass through the connecting piece 63 again when passing through the embedded pipeline duct 61. By installing the connecting piece 63 on the two pipe segments, not only can the cable pass through for protection, but the connecting piece 63 can also strengthen the connection tightness between the two pipe segments.

[0035] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
