Description

Technical Field

[0001] The utility model belongs to the field of building construction, and specifically relates to a lighting and ventilation assembly for a tunnel. Background Art

[0002] With the rapid progress of urban infrastructure construction, more and more cities are seeing the emergence of underpass and overpass structural projects. In the process of urban underground tunnel construction, energy conservation, environmental protection and smart construction have been elevated to a very new level. Due to the uniqueness of tunnel engineering, which is a large-volume confined space, sufficient various infrastructures need to be configured to ensure the normal operation of the tunnel. The existing technology is to set up an inspection layer inside the tunnel during tunnel construction, and install ventilation and lighting equipment inside the inspection layer. Due to the closed nature of the tunnel itself, the tunnel requires auxiliary lighting and ventilation equipment during construction and subsequent use to assist in the normal construction and use of the tunnel. At present, the installation of ventilation and lighting systems in tunnels is often carried out after the overall construction of the tunnel is completed. Temporary ventilation systems such as temporary lighting and blowers are used during construction, which have low reliability and low lighting and ventilation efficiency. The ventilation and lighting systems cannot be well integrated into the overall construction process of the tunnel, and secondary construction is required inside the tunnel, which prolongs the construction period. Summary of the Invention

[0003] In order to solve the problem that a temporary lighting and ventilation system needs to be used for temporary ventilation and lighting during tunnel construction, the ventilation and lighting effects are poor, and the ventilation and lighting systems need to be installed after the tunnel construction is completed, resulting in a long construction period, the utility model proposes a lighting and ventilation assembly for tunnels to solve the above problems.

[0004] A lighting and ventilation assembly for a tunnel comprises an outer shell, which provides sufficient installation space inside. The inner surface of the outer shell is provided with a fixing groove, which provides a fixed notch for the connection of internal components to ensure a stable connection. The fixing grooves are evenly distributed along the inner surface of the outer shell. The outer shell is provided with an installation opening on the side away from the installation surface to provide a reserved position for equipment connection and controller installation. The installation opening is equipped with an equipment mounting frame, which is mainly made of steel and is bolted to the inside of the shell and firmly connected to the shell to provide an installation fulcrum for lighting equipment and ventilation equipment. A sealing plate is installed at one end of the outer shell, and an air duct and a reserved pipe are installed inside the outer shell.

[0005] Furthermore, an air duct is provided inside the air duct, and a fixing block is provided on the contact surface between the air duct and the inner surface of the shell, and the fixing block cooperates with the fixing groove on the inner surface of the shell; a connector with a reserved notch shape is welded around the entire air duct to ensure that the air duct is firmly connected to the inner surface of the shell.

[0006] Furthermore, the outer surface of the reserved tube is provided with a fixing block, and the fixing blocks are evenly distributed along the outer surface of the reserved tube. The reserved tube includes a plurality of tubes, and connecting pieces are installed between adjacent reserved tubes, and the connecting pieces cooperate with the fixing blocks;

[0007] Furthermore, a plurality of the reserved tubes are combined to form a multi-channel reserved tube, and a cavity is provided in the center of the multi-channel reserved tube.

[0008] Furthermore, a baffle is provided inside the equipment mounting frame, and the surface of the baffle can adjust the size of the reserved holes for the upper and lower outlets according to the relevant requirements of the internal reserved pipelines to facilitate the installation of equipment pipelines. An opening is provided on the outer surface of the equipment mounting frame, and the opening is facing the air duct and the reserved pipe. The opening is mainly used to pass through the upper and lower lines to connect multiple air ducts and the reserved pipe.

[0009] Furthermore, the shell includes multiple shells, and the multiple shells are installed end to end, with a sealing plate installed at the head end of the shell and a sealing plate installed at the tail end of the shell; a plurality of connection ports are opened on the surface of the sealing plate, and the connection port openings correspond one by one to the inlets and outlets of the air duct and the reserved pipe respectively; the positions of the openings on the surface of the sealing plates at the head end and the tail end are adjusted according to the positions of the air duct and the reserved pipe in the shell to achieve mutual correspondence, ensuring that the air inlet and outlet of the air duct will not be obstructed, ensuring that the reserved pipe can transport the cable internally smoothly, and avoiding uneven openings causing damage to the cable sheath; the main material of the sealing plate is the same as that of the shell, and the remaining openings inside the shell can be set by yourself according to the conditions of the device connected at the end.

[0010] Furthermore, the air duct and the reserved pipe are symmetrically distributed along the central axis of the installation opening.

[0011] Furthermore, the blocking plate is welded to the outer shell, and the air duct and the reserved pipe are arranged in parallel.

[0012] Furthermore, the shell is formed by welding steel plates, the seams are fully welded and subjected to fireproofing and anti-corrosion treatment; the cost is low and the production is easy.
