Fresh air duct and emergency evacuation exit combined construction structure for subway
The invention discloses a fresh air duct and emergency evacuation exit combined construction structure for a metro, relates to the technical field of fresh air duct structures, solves the technical problem that in the prior art, a metro fresh air duct needs to independently go out of the ground, and consequently the occupied area is large, and comprises an emergency evacuation exit independently going out of the ground, and an open staircase is arranged in the emergency evacuation exit. The fresh air duct is adjacent to the open staircase and arranged on the side close to the second stair, and a top plate of the fresh air duct is lower than the ground; a partition wall is arranged between the fresh air duct and the open staircase; a fresh air opening is formed in the position, located above the second stair, of the partition wall and provided with a first safety protection net. The effective air inlet area of the fresh air opening is at least 12 m < 2 >, and the effective air inlet area of the open staircase is larger than or equal to the effective air inlet area of the fresh air opening. According to the combined construction structure, the influence on the landscape around the urban main road is reduced, and the land acquisition difficulty is also reduced.
本发明公开了一种地铁用新风道与紧急疏散口合建结构，涉及新风道结构技术领域，解决现有技术中地铁新风道需要单独出地面导致占地面积较大的技术问题，包括独立出地面的紧急疏散口，所述紧急疏散口内设置有敞开楼梯间，其中，所述新风道与所述敞开楼梯间相邻，且设置在靠近第二跑楼梯的一侧，所述新风道的顶板低于地面；所述新风道与所述敞开楼梯间中间设置有分隔墙；所述分隔墙上位于所述第二跑楼梯以上的位置设置有新风口，所述新风口设置有第一安全防护网；所述新风口的有效进风面积至少为12m2，所述敞开楼梯间的有效进风面积大于等于所述新风口的有效进风面积；所述合建结构减少了对城市主干道周边景观的影响，也降低了征地难度。
