Problems solved by technology

[0005] The intersections at both ends of the underground passage are set on the sidewalk and span more than 70 meters. The flow exchange effect between the air in the middle of the underground passage and the outside air is weak, which will lead to an increase in the concentration of carbon dioxide in the air in the underground passage, which may lead to of pedestrians feel uncomfortable

Embodiment 1

[0057] refer to figure 1 , is a municipal road disclosed by the present invention, including a channel 1 and a ventilation device 2 .

[0058] Passage 1 is located underground, and the entrances and exits at both ends of passage 1 are located on the sidewalks on both sides, and pedestrians pass through passage 1 to cross the road;

[0059] The ventilator 2 is provided above the channel 1. When the vehicle passes, the road vibrates and the vibration is transmitted downward. At this time, the ventilator 2 absorbs the vibration, thereby weakening the vibration of the channel 1, and uses the energy of the vibration to push the air flow , to realize the ventilation of channel 1, so as to reduce the discomfort of pedestrians in channel 1.

[0060] refer to figure 2 , 3 , the ventilation device 2 includes a sleeve 21 , a slider 22 and a spring 23 .

[0061] The axis of sleeve 21 is vertically arranged, and its upper and lower ends are closed, and then forms cavity in sleeve 21, ...

Embodiment 2

[0077] The difference between embodiment two and embodiment one is:

[0078] refer to Figure 7 , 8 , the axis of the sleeve 21 is set horizontally, and embedded on the partition 26, the slider 22 is slidably arranged in the sleeve 21, and divides the cavity in the sleeve 21 into two chambers 214, each chamber 214 is correspondingly provided with an air outlet 211 and an air inlet 212, and the air inlet 212 is located below the partition 26, the air outlet 211 is located above the partition 26, and the air outlet 211 and the air inlet 212 are correspondingly provided with shrapnel 24, and cover the air outlet 211 The shrapnel 24 is located outside the sleeve 21 , and the shrapnel 24 covering the air inlet 212 is located in the cavity 214 .

[0079] The implementation principle of this embodiment is: the vibration caused by the passage of the vehicle cooperates with the spring 23, so that the slider 22 moves back and forth;

[0080] When the slider 22 moves to the left, the ...

Embodiment 3

[0085] A construction method for municipal roads, comprising

[0086] S1: Excavate trenches along the width of the road and clean them up;

[0087] S2: Pouring the channel 1 in the first embodiment in the trench;

[0088] S2.1: When pouring channel 1, pre-buried pipes are placed on the side wall and top wall of channel 1 to form air channel 11,

[0089] S3: install the ventilation device 2 on the channel 1;

[0090] S3.1: The casing 25, the partition plate 26, the sleeve 21, etc. are prefabricated and covered to the upper end of the channel 1;

[0091] S3.2: install the air pipe 27 on the upper end of the housing 25;

[0092] S4: Excavate the road groove along the extension direction of the road and clean it up. The road groove is flush with the top of channel 1;

[0093] S5: Pour concrete in the road groove and above the channel 1 to lay the road base, and level it;

[0094] S6: Evenly lay asphalt on the road base.

Abstract

The invention relates to a municipal road, which includes a passage, and is characterized in that: a ventilation device is arranged in the passage, and the ventilation device includes a sleeve, a slider and a spring, and the two ends of the sleeve are closed, so that The slider is slidably embedded in the sleeve, and there is a sliding seal between the slider and the inner wall of the sleeve. The slider and the inner wall of the sleeve enclose a chamber, and the two ends of the spring are respectively connected to the slider, The sleeve, and the spring expands and contracts along the axial direction of the sleeve, and the sleeve is also provided with an air inlet and an air outlet, and the air inlet and the air outlet are connected to the chamber, and the air inlet, The air outlets are provided with one-way ventilation components, one of the air inlets or air outlets is connected to the inside of the channel, and the other is connected to the outside of the channel. In the present invention, when the vehicle passes, the slider vibrates, and the vibration energy is used to push the air flow to realize the ventilation of the passage, and at the same time, the vibration of the road is weakened, which is beneficial to reduce the discomfort of pedestrians in the passage.

Description

technical field [0001] The invention relates to the technical field of municipal facilities, in particular to a municipal road. Background technique [0002] Municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads and bridges. [0003] At the intersection, the two sides of the road are usually connected by an overpass or an underground passage, so that pedestrians can cross the road. [0004] Roads usually include motor vehicle lanes in the middle, non-motor vehicle lanes on both sides, and sidewalks on the outermost side. If it is a first-class road, a separation zone must be set up, such as...
