The bottom end of the first mounting component 10 is detachably connected to the top end of the pre-embedded component 20, and the first mounting component 10 is tightly fitted to the top surface of the utility tunnel 2. The top end of the second mounting component 30 is detachably connected to the bottom end of the pre-embedded component 20, and the second mounting component 30 is tightly fitted to the bottom surface of the utility tunnel 2, thus sealing the measuring opening. The bottom of hole 201; with this configuration, after the sealing device 1 is installed in the measuring hole 201 of the integrated utility tunnel 2, concrete is poured into the measuring hole 201 of the integrated utility tunnel 2. After the concrete has initially set, the first installation component 10 and the second installation component 30 are removed, the pre-embedded component 20 is embedded in the concrete, and the pre-embedded component 20 is blocked with mortar. Compared with the method of using steel pipe 1112 to support the opening, this improves construction efficiency and shortens the construction period. At the same time, the first installation component 10 and the second installation component 30 can be reused, saving costs.

[0023] The bottom end of the first mounting component 10 and the top end of the pre-embedded component 20 can be connected by a thread, or the bottom end of the first mounting component 10 and the pre-embedded component 20 can be connected by a plug-in connection. This embodiment does not impose any restrictions on this.

[0024] It should be noted that the connection method between the top of the second mounting component 30 and the bottom of the pre-embedded component 20 is basically the same as the connection method between the bottom of the first mounting component 10 and the top of the pre-embedded component 20.

[0025] The usage process of the sealing device 1 for measuring openings of the integrated utility tunnel provided in this embodiment is as follows: the sealing device 1 is installed on the measuring hole 201 of the integrated utility tunnel 2, the second installation component 30 is sealed on the bottom surface of the measuring hole 201, concrete is poured into the measuring hole 201, and after the concrete has initially set, the first installation component 10 and the second installation component 30 are removed from the pre-embedded component 20, and the pre-embedded component 20 is filled with mortar.

[0036] Specifically, the pipe body 21 is inserted into the measuring hole 201 of the integrated pipe gallery 2. After concrete is poured into the measuring hole 201, the pipe body 21 is embedded in the concrete of the measuring hole 201. The water-stop plate 22 is embedded in the concrete of the measuring hole 201. During use, the center line of the pipe body 21 is set parallel to the center line of the connecting threaded rod 12. In some feasible ways, the center line of the pipe body 21 is set collinear with the center line of the connecting threaded rod 12.
