Embodiment 1

[0015] Example 1: see figure 2 , the present invention is provided with left and right sides approach 1 and transverse aisle 2, is provided with ladder or slope 3 at the junction of approach 1 and approach 1 and transverse aisle 2. On the right approach road, a drainage member 4 is arranged, and the drainage member 4 is arranged in the middle part of the inner side of the approach road by the roadside, and the drainage member 4 is trapezoidal.

Embodiment 2

[0016] Example 2: see image 3 , the present invention is provided with left and right sides approach 1 and transverse aisle 2, is provided with ladder or slope 3 at the junction of approach 1 and approach 1 and transverse aisle 2. Two drainage components 51 and 52 are arranged on the right approach, and the drainage components 51 and 52 are respectively arranged on the right approach at the connection between the right approach and the upper and lower sides of the transverse aisle 2, and the drainage component 4 is a right-angled trapezoid.

Embodiment 3

[0017] Embodiment 3: see Figure 4 , similar to Embodiment 1, the difference is that the drainage member 6 is triangular in shape, and the two sides of the triangle are arc-shaped. The location of the steps or slopes at the junction of the right approach road 1 and the transverse aisle 2 and figure 2 different. exist Figure 4 , the design of the ladder or ramp 3 of the left approach 1 is the same as figure 2 same.

Abstract

An asymmetry type underground passage for guiding the natural wind to convect, relates to a design or a layout of the road, which is provided with a left and a right approach and a cross runway. The approach is equipped with a ladder or a grade, and at least a approach is provided with a conduction component. If one approach is equipped with a conduction component, the conduction component can be arranged on the approach inside middle part near the roadside, or the conduction component is arranged on the approach connected with the cross runway. If two approaches are provided on the conduction component, the conduction component can be arranged respectively on two approaches connected with the cross runway, wherein the joint of the approach and the cross runway is provided with a ladder or a grade. The conduction method is adopted to guide the air for orientation flow in the cross runway, to make the cross runway ventilative, which effectively eliminates the moisture and the peculiar smell in the cross runway, prolongs the service life of the relative apparatus and the equipment in the runway.

Description

technical field [0001] The invention relates to a road design, in particular to an asymmetrical underground passage which can guide natural wind convection. Background technique [0002] In urban road construction, in order to reduce the impact of pedestrians crossing the road on traffic, in addition to setting up zebra crossings and pedestrian bridges, building underground passages is a safer measure. Usual underground passage in the city is provided with left and right sides approach road 1 and transverse aisle 2, all is provided with ladder or slope on the approach road, what have also is provided with step or slope 3 at the junction of approach road and transverse passage (referring to figure 1 ). However, due to the unreasonable structural design of the existing underground passages, the air circulation in the approach passages, especially the transverse passages, is poor, and the humidity in the transverse passages is high, often having peculiar smell. [0003] The i...
