Embodiment Construction
[0044] In this embodiment, an underground pedestrian passage based on the inner and outer ring structures, such as figure 1As shown, the underground pedestrian passage is composed of a variable speed passage 1, a constant speed passage 2 and a load-bearing structure 3; the outer side of the load-bearing structure 3 is provided with the uniform speed passage 2 along a ring; the outer side of the uniform speed passage 2 is provided with a variable speed passage 1 along a ring ; thus forming an inner and outer ring structure with co-direction transmission; the total width of the channel is 11m-13m, which are respectively composed of a 4m wide speed change channel 1, a 6m wide uniform speed channel 2 and a 1m wide load-bearing structure 3. The overall height of the channel is 4m, and the length depends on the specific situation depends. The load-bearing structure 3 is composed of a load-bearing wall with a width of 1m and a height of 4m, and the material is reinforced concrete. Th...
