This application relates to a ventilation system for underground civil air defense projects, which includes several groups of brackets suspended on the top of the wall and several outer and inner pipes arranged at intervals, and the adjacent outer pipes and the inner pipes are connected end to end connected, and the end of the outer tube is sleeved on the end of the inner tube, the outer tube is erected on two adjacent brackets, and the bracket is located at the junction of the outer tube and the inner tube; the outer tube and the The connection between the inner pipes is provided with several horizontal pipes, and several of the horizontal pipes are arranged on the two side walls of the outer pipe and the two side walls of the inner pipe; the connection between the outer pipe and the inner pipe is provided with Two insertion rods located on both sides of the outer tube and parallel to each other, the insertion rods are passed through the ends of several horizontal tubes protruding from the outer tube. The present application has the effect of improving the installation efficiency of the ventilation system.
Description
technical field [0001] The present application relates to the field of civil air defense engineering, in particular to a ventilation system for underground civil air defense engineering. Background technique [0002] Civil air defense projects are also called civil air defense fortifications, which refer to underground protective buildings built separately to protect personnel and material shelters, civil air defense command, and medical rescue in wartime, as well as basements that can be used for air defense in wartime when combined with ground buildings. The ventilation system of the underground civil air defense project ensures the air circulation of the underground protective building and the quality of the indoor air environment, and the ventilation duct is the main component of the ventilation system, so the reasonable design and installation of the ventilation duct is particularly important. [0003] In related technologies, ventilation ducts generally have a pluralit...
