An underground pedestrian passage based on inner and outer ring structures

Abstract

The invention discloses an underground pedestrian passageway based on an inner-outer-ring structure. The underground pedestrian passageway consists of a variable-speed passageway, a constant-speed passageway and a load bearing structure; the constant-speed passageway is circumferentially arranged at the outer side of the load bearing structure; the variable-speed passageway is circumferentially arranged at the outer side of the constant-speed passageway, so that a co-rotating transmission inner-outer-ring structure is formed; the variable-speed passageway consists of three automatic pedestrian passageways of different speeds and a safety walking passageway; the constant-speed passageway consists of an automatic rapid pedestrian passageway; an isolation guard railing and an emergency guard railing are arranged between the variable-speed passageway and the constant-speed passageway, and the emergency guard railing is provided with an emergency switch; a plurality of axial-flow fans and fire smog detectors are arranged in the passageways. The underground pedestrian passageway is more environment-friendly, high-efficient and convenient, so that the short-distance traffic jam problem can be relieved by utilizing the least land resource and the lowest economic cost, the middle-short-distance traveling time is shortened, and the traveling efficiency is improved.

Description

technical field [0001] The invention relates to a walkway, in particular to an underground walkway based on inner and outer ring structures. Background technique [0002] With the development of the times, the population has risen sharply, accompanied by a sharp increase in traffic flow. The construction of viaducts is increasing day by day, and the number of private cars is also increasing crazily. Both the government and the society are advocating common transportation, and the construction of subway (light rail) and dedicated bus lanes is also vigorously developed. Although these transportation facilities and travel tools provide great convenience in our lives, they also have some negative effects. [0003] Disadvantages of viaduct: 1. The establishment of viaduct will occupy the driving passage under the bridge. 2. The viaduct is too circuitous, and the positions of the upper and lower viaducts are relatively fixed. [0004] Disadvantages of private cars: 1. The incr...

AI Technical Summary

Problems solved by technology

[0003] Disadvantages of viaduct: 1. The establishment of viaduct will occupy the driving channel under the bridge

2. The viaduct is too circuitous, and the position of the upper and lower viaducts is relatively fixed

[0004] Disadvantages of private cars: 1. The increase of private cars will lead to increased traffic congestion

2. The increase of private cars also has an adverse effect on air quality

[0005] Disadvantages of subway light rail: 1. Drilling and digging a large underground space, high construction cost; 2. Long construction period, due to the need to dig tunnels, lay rails, install equipment and various debugging work in the early stage

[0006] Disadvantages of public transportation: 1. In densely populated cities, the speed of buses is greatly reduced, and sometimes it is not as fast as that of bicycles

2. Due to the uncertainty of urban traffic, the arrival time of buses has also become an uncertain factor

[0009] 2) The increase in the number of ground traffic carrying facilities at the same time leads to ground traffic congestion due to space constraints;

[0010] 3) The development of the subway has facilitated people's travel to a certain extent, but the shortcomings of the subway, such as long construction period, many maintenance times, and many restrictions on the location of the entrance and exit stairs, cannot be ignored.

[0011] 4) For viaducts, road sections that require a short distance up and down and road sections that have already built multiple viaducts cannot be constructed

[0014] Through research, it is found that the comparative document CN 104278606 A only sets slopes at intersections, allowing vehicles to pass on the slopes, and pedestrians to pass through the passages at the bottom of the slopes, and does not really improve the traffic speed by changing the traffic flow on the ground, especially This structural setting determines that the slope of the slope cannot be too large, and the height is limited, which increases the length of the entire slope, and if it is used on a large scale, it will also lead to a waste of resources
