[0001] The utility model relates to the technical field of utility tunnels, in particular to a ventilation opening structure of a utility tunnel. Background Technique

[0002] A utility tunnel is a structure and ancillary facilities built underground in a city for accommodating two or more types of urban engineering pipelines. The main structure of the underground utility tunnel is mainly arranged underground. In order to enable the internal of the tunnel to have a good operation environment, air vents connected to the outside of the tunnel are provided, which are called ventilation openings of the utility tunnel.

[0003] After retrieval, in the application with the patent publication number CN212027271U, a ventilation opening structure of a utility tunnel is disclosed, which includes a plurality of installation walls and an installation roof. The upper part of the installation wall is provided with louvers, the top of the installation wall is provided with a top frame, the bottom of the installation wall is provided with a bottom frame, and the two side edges of the installation wall are respectively provided with a lock convex edge frame and a lock groove frame. The installation walls are installed through connecting columns, and the side wall of the connecting column is provided with a convex edge connecting end and a groove connecting end, so that the utility tunnel can have good waterproof and fireproof performances.

[0004] However, due to the setting of the installation wall and the connecting column, the column is formed by pouring concrete, which leads to inconvenient overall installation of the device, resulting in low construction speed. At the same time, due to the setting of the installation wall and the louvers, rainwater from the outside is likely to enter the utility tunnel through the louvers, with low waterproof performance. The closing of the louvers also requires manual operation by workers, with a large amount of labor and inconvenience in closing the louvers.

[0005] Therefore, we propose a ventilation opening structure of a utility tunnel. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a ventilation opening structure of a utility tunnel, which solves the problems of low installation and construction efficiency and low waterproof performance of the existing device.

A ventilation opening body adapted to the position and specification of the collecting pipe is fixedly installed on the top surface of the ground. Uniformly distributed ventilation holes are opened on the outer wall of the ventilation opening body;

[0009] The collecting pipe penetrates through the through-hole and protrudes above the ground. A filter screen with a matching specification is assembled on the top surface of the collecting pipe. The connecting pipe is L-shaped, and the right end of the connecting pipe is connected to the outer wall of the collecting pipe. There is a distance of 30 cm between the bottom of the collecting pipe and the connection part of the connecting pipe.

[0010] Preferably, there is a distance of 40 cm between the ventilation hole and the ground, which can prevent the water on the ground from flowing into the interior of the ventilation port body through the ventilation hole, improving the waterproof ability.

[0011] Preferably, a seat with a matching specification is fixedly installed on the top surface of the ventilation port body, which can facilitate people to sit on the ventilation port body to rest, improving the practicability and aesthetic degree.

[0012] Preferably, the cross-section of the seat is trapezoidal, and the included angle between the side surface of the seat and the horizontal plane is 115 degrees, which can improve the comfort of people sitting on the ventilation port body.

[0013] Preferably, a sulfoaluminate cement waterproof material is assembled on the contact surface between the collecting pipe and the ground, which can improve the stability of the collecting pipe and also improve the sealing performance between the collecting pipe and the ground.

[0014] Preferably, a sealing gasket is fixedly installed on the contact surface between the ventilation port body and the ground, which can improve the sealing performance between the ventilation port body and the ground and prevent the outside rainwater from entering the ventilation port body.
