When assembling two cable gallery 1, the socket 11 at one end of the cable gallery 1 is inserted into the socket 12 at one end of the other cable gallery 1. The surface of the socket 11 at one end of the cable gallery 1 and the surface of the socket 12 at the other end of the cable gallery 1 are both arranged to be uneven, so as to increase the friction between the socket 11 of the cable gallery 1 and the socket 12 of the other cable gallery 1, so that the connection between the two adjacent cable gallery 1 is more firm. A plurality of first sealing rings 13 are sleeved on the outer periphery of the socket 11 of the cable duct corridor 1. When the socket 11 of the cable duct corridor 1 is inserted into the socket 12 of another cable duct corridor 1, each first sealing ring 13 is inserted between the socket 11 of the cable duct corridor 1 and the socket 12 of another cable duct corridor 1 to fill the gap between the socket 11 of the cable duct corridor 1 and the socket 12 of the adjacent cable duct corridor 1, and cement mortar is filled between the socket 11 of the cable duct corridor 1 and the socket 12 of the adjacent cable duct corridor 1, so as to achieve a good sealing effect between the two adjacent cable duct corridors 1.
[0034] Reference Figure 3 , Figure 4 and Figure 5 The standard length of each cable corridor 1 is set to 3.0m. A waterproof layer 2 is provided at the bottom of the cable duct. After each cable duct is buried underground, the waterproof layer 2 is provided to prevent groundwater from seeping into the cable duct, thereby providing a waterproof and sealing effect on the cable duct. In order to protect the waterproof layer 2 at the bottom of the cable corridor 1, a cushion layer 3 is provided at the bottom of the waterproof layer 2. The cushion layer 3 is provided to prevent the cable corridor 1 from being damaged by the waterproof layer 2 when it is transported or buried underground.

The end corners of the prefabricated cover plate 5 are all designed with rounded corners to avoid the prefabricated cover plate 5 from being bumped during transportation and construction, resulting in missing edges and corners. In addition, in order to ensure that the prefabricated cover plate 5 is firmly installed at the top plate opening 14, a plurality of first embedded parts 51 are provided on the circumference of the prefabricated cover plate 5, and a plurality of second embedded parts 15 are provided on the cable tunnel 1 accordingly, and the plurality of the second embedded parts 15 are located on the circumference of the top plate opening 14.
