The difference between a culvert and a channel, and what is the difference between a culvert and a t

1. Tunnel: Tunnel is an engineering building buried in the stratum, which is a form of human use of underground space.

2. Culvert: Culvert refers to the drainage channel (water channel) built below the road surface under the roadbed in order to make the highway pass smoothly through the canal without hindering traffic in the construction of highway engineering, and the water can flow under the highway through this structure. It is used to drain floodwater across natural valleys and depressions, or to cross large and small roads as an override for people, livestock and vehicles, or to irrigate farmland as a canal.

The culvert is mainly composed of the cave body, foundation, end and wall, etc., which is built according to the principle of the communicator, and is commonly built with materials such as brick, stone, concrete and reinforced concrete. Generally, the aperture is small, and the shape is tube-shaped, box-shaped and arch-shaped, etc., and the bridge and culvert are technically divided by the span diameter. Generally, more than 5 meters (exclusive) is called a bridge, and the following is called a culvert.

However, the round pipe culvert and the box culvert are called culverts regardless of the aperture and span. But in fact, the main difference between a culvert and a bridge is that there is generally a fill on the culvert, while the track is laid directly on the bridge. From the side, the culvert looks like a hole dug in the roadbed, which is broken off at the bridge.

3. Difference: The tunnel is open to traffic at both ends, the culvert is open to water, the tunnel is a hole through the mountain, under the soil layer, for vehicles to exercise, the culvert is to cross the valley, etc., the span is less than 5m, below the roadbed, usually as a drainage or pedestrian passage, more than 5m, less than 20m is called a small bridge, because of its simple structure, so it is classified with a culvert.

Culverts are designed to span ravines, etc., with a span of less than 5 m, under the roadbed, and are usually used as drainage or pedestrian passages.

Passages refer to walkways that can be passed, such as tunnels, culverts, etc., which belong to passages.

My personal understanding is actually about the same, in essence, most of them are reinforced concrete cover culverts. It's just that the objects that pass through below are different. Culverts mostly refer to water, and passages mostly refer to people, livestock, motorcycles, etc.

Difference Between Culvert and Tunnel:

1. Different road signs.

Culvert. <>

Tunnel. <>

2. Different uses.

The tunnel is a hole through the mountain, under the soil layer, for vehicles to travel. The culvert is open to water, and is designed to span ravines, etc., with a span of less than 5m, under the roadbed.

3. The construction location is different.

Culvert refers to the drainage channel (water passage) built below the road surface under the roadbed in order to make the highway pass through the canal smoothly without hindering traffic in the construction of highway engineering. A tunnel is an engineering building buried in the ground and is a form of human use of underground space.

Summary. The difference between culvert and tunnel is: culvert refers to the drainage channel that is built below the road surface under the roadbed in order to make the highway pass smoothly through the canal without hindering traffic in highway engineering construction, and the tunnel is an engineering building buried in the stratum, which is a form of human use of underground space.

The difference between culvert and tunnel is: culvert refers to the construction of the road in the construction of the public liquid quiet road project, in order to make the highway pass smoothly through the canal and not hinder the traffic, the drainage channel under the roadbed is built to let Qing Qing below the road surface, and the tunnel is an engineering building buried in the stratum, and the slag is a form of human use of underground space.

Culvert: refers to the drainage hole built below the road surface under the roadbed in order to make the highway pass smoothly through the canal without hindering traffic, and the water can flow through the bottom of the highway through this structure. It is used to drain floodwater across natural valleys and depressions, or to cross large and small roads as a pedestrian road for people, livestock and vehicles, or to irrigate farmland as a canal.

A tunnel is an engineering building buried in the ground and is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

The structure of the tunnel consists of two parts: the main building and the auxiliary equipment. The main building is composed of the cave body and the slag door of the cave source, and the auxiliary equipment includes the Mengzhou car cave, fire fighting facilities, emergency communication and anti-drainage facilities, and the long tunnel also has special ventilation and lighting equipment.

In the construction of traffic engineering, culverts and tunnels are often used. Culverts and tunnels are both passages through obstacles, but they are different in nature.

Definition and characteristics of culverts.

A culvert, as the name suggests, is a structure that "covers the cave". In layman's terms, it is a pipeline built under the traffic routes such as rivers, railways, and highways to ensure the smooth flow of traffic. The characteristics of the culvert are:

It is mostly used for the design of traffic pipelines on flat surfaces.

The main function is to cross obstacles such as roads and solve problems such as water on the road.

There is no need for too high exploration and construction costs.

The structure is simple, and the decoration and other work are relatively easy to complete.

Definition and characteristics of tunnels.

Tunnels are tunnels excavated underground, which are more difficult to construct than culverts, and have a wider range of applications. The characteristics of the tunnel are:

It is mostly used in traffic engineering on vertical and horizontal planes, such as highways, railways, etc.

The main function is to connect the areas with different geological and topographic conditions on both sides.

The construction period is long and the construction cost is high.

The structure is complex, and the decoration and other work are difficult.

The difference in construction between the two.

There are also some differences between the culvert and the tunnel during construction:

The construction of culverts can generally be carried out without affecting traffic, and the construction time is relatively short; The tunnel construction period is long, and traffic restrictions need to be imposed during the construction process.

Culverts are usually constructed with closed pipes, and tunnels should be excavated in different ways according to their needs, and the construction technology is also different.

The construction cost of the tunnel is generally higher than that of the culvert, mainly because the tunnel needs to be specially designed according to the geology, terrain and other conditions, and the construction of high-strength materials is used.

The scope of application of both.

There are also some differences in the practical scope of application of culverts and tunnels:

Culverts are mainly used in water-wading projects (such as railways, highways and rivers) to solve problems such as water and drainage on the road.

The tunnel is mainly used in the construction of municipal facilities such as traffic engineering, tap water, and electric power, and is used to break through topographic obstacles and connect areas with different conditions such as transportation, water supply, and power supply on both sides.

In short, although culverts and tunnels are indispensable facilities for building related objects and traffic projects, there are obvious differences in their nature, characteristics, construction differences and application scope, and the selection should be considered according to actual needs.

People occasionally see culverts and tunnels on traffic roads, so let's understand the difference between culverts and tunnels.

First, the difference in shape

Subject 1 can distinguish between culverts and tunnels in the following way: the culvert is like a hump bridge with extensions on both sides, while the tunnel is like a door, and on the traffic road, the signs of the two are also different.

Second, the difference in role

Culverts are designed to cross ravines, etc., underneath the roadbed, and are usually used as drainage or pedestrian passages. The tunnel is a hole through the mountain, under the soil layer, for vehicles to travel. Culverts are used to drain floodwater across natural valley depressions, or to cross large and small roads as standways for people, livestock and vehicles, or to irrigate farmland as canals.

Third, the classification is different

Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. The structure of the tunnel consists of two parts: the main building and the ancillary equipment. The culvert is mainly composed of the cave body, the foundation, the end and the wall.

The culverts used in the construction of highway projects are the most box culverts. The world's longest two-hole one-way road tunnel. It starts from Qingcha in Chang'an District, Xi'an in the north, and reaches Yingpan Town, Zhashui County, under the jurisdiction of Shangluo City in the south, with a total length of kilometers and a design speed of 80 kilometers per hour, and people can drive 15 minutes to cross the Qinling Mountains, which is the dividing line between the north and south of China.
