Highways have different regulations in different countries, times and scientific research and academic fields. According to the Chinese road engineering technology Standard (JTG B01-2014): the highway is a multi-lane highway which is specially used for cars to drive in different directions and lanes and completely control the entrance and exit. The annual average daily designed traffic volume of the highway is preferably more than 15000 passenger cars, and the designed speed is 80-120 kilometers per hour. And at high speed, passing overpasses or overpasses, or height limiting devices or toll stations are arranged at intervals.

The trees in the central separation zone of the highway can play a role in preventing dizziness for drivers driving on the highway, and also have a role in beautifying the environment, and the trees are important components of the highway. Meanwhile, the existing urban expressway and main road also have a greening structure similar to that of the expressway.

The inventor finds that in the existing highway maintenance system, the green plants of the central separation zone of the highway are maintained by adopting a sprinkling truck sprinkling irrigation mode, the maintenance mode is relatively simple and easy to master, but the green plant planting soil of the central separation zone of the highway is generally positioned on a highway subgrade and is not connected with the soil of the ground, so the large water sprinkling irrigation method has the advantages of wide coverage, frequent operation, poor irrigation effect and difficulty in controlling the irrigation water consumption; in addition, the spray irrigation operation on the expressway with high speed and large traffic flow can easily cause rear-end accidents or vehicle pressing, and when the spray irrigation water flows to a traffic lane, the vehicles running at high speed can easily slip, thereby causing serious traffic accidents.

The following describes the specific arrangement of the present embodiment in detail with respect to the green belt 3 of the road surface 1 having a specific end as a work object. Referring to fig. 1, a green belt 3 of a road surface 1 at one end is selected, the green belt 3 of the road surface 1 is a horizontal road section, a section of the green belt 3 of the road surface 1 is penetrated by a road bridge 2, the height of the road bridge 2 relative to the road surface 1 of the expressway is 5.5m, the length of the green belt 3 of the road surface 1 is 2km, the width of the green belt is 3m, and the planted plants 31 are dragon juniper, crape myrtle and wintergreen.

One end of the pipe fitting 5 is positioned at the roadside of the highway, one section of the pipe fitting 5 is fixedly connected with the overpass 2, the pipe fitting 5 is laid below the ground surface of the green belt 3 on the road surface 1, and the height of the overpass 2 is 5.5m, so the pipe fitting 5 has a self-flowing function, and after water enters the pipe fitting 5, the water flows through the pipe section connected with the overpass 2, has gravitational potential energy and can automatically flow to the tail end of the pipe fitting 5.

The pipe in this embodiment is simultaneously connected to a plurality of tanks 7, but in other embodiments, one tank 7 may be connected, and the connection of one tank 7 may occur in a very short road surface 1 green belt 3 section. The length of greenbelt 3 in this embodiment is 2.2km, arranges a jar body 7 every 0.5m, then in this embodiment needs 4400 jar bodies 7, 4400 jar bodies 7 bury respectively in the side of one or more green plant 31 plant root systems to supply water directly to the root system of plant.

The beginning of pipe fitting 5 can connect water supply source, the end connection discharge valve of pipe fitting 5 to avoid the pipe fitting 5 flatulence that air pressure in the aquatic caused.

It will be appreciated that the water supply source in this embodiment may be a water supply device such as a sprinkler, emergency water supply 4 or fire hydrant which can conveniently pump water into the pipe 5.

The water baffle 6 is connected to the inner wall of the pipe fitting 5, and the height of the water baffle 6 is smaller than or equal to the radius of the pipe fitting 5; at the same time, the pipe 5 is inclined downwards with respect to the ground surface of the green belt 3 of the road surface 1.

In order to further ensure that each tank 7 can obtain a sufficient water source, the pipe 5 in this embodiment is inclined downwards relative to the ground surface of the green belt 3 of the road surface 1.

It will be appreciated that each tank 7 is connected to the pipe 5 by a tee.

In order to ensure that each tank 7 stores enough water, the rear section (front and rear in relation to the direction of water flow) of the pipe section where the pipe 5 communicates with the tank 7 is provided with a water baffle 6, and the water baffle 6 is used for blocking the flow of water, that is, when the flow rate of water is small, such as when the actual flow rate of water is one tenth of the maximum flow rate of water, because the pipe 5 is inclined, the water baffle 6 can accumulate a part of water, so that the accumulated water flows into the tank 7.

The tank body 7 is a cylindrical tank body 7.

The aperture of the small hole 71 is smaller than 0.1mm, and when the aperture of the small hole 71 is within the range, powder and gravel in soil can be isolated, and only water can permeate through the small hole.

when the water content of the soil is higher than 100%, the water in the soil can permeate into the tank body 7.

It is understood that in the specific environment described in example 1, the specific steps of the irrigation method disclosed in this example when the water content of the soil is less than 100% are as follows:

1) calculating the water supply amount to ensure that each tank body 7 can be filled with water;

2) supplying water to the pipe 5 using the water supply cart 4;

3) after the water is filled, the water supply cart 4 stops supplying water to the pipe 5.

When the water content of the soil is higher than 100%, the condition usually occurs after flood irrigation or raining, and at the moment, water in the soil can permeate into the tank body 7 through the wall of the tank body 7, so that rainwater is accumulated in the tank body 7, and when the water content of the soil is reduced, water can permeate out of the tank body 7.

Example 4

Embodiment 4 discloses a road green belt irrigation method based on the system of embodiment 2, wherein the pipe fitting can be connected with a water source, and water flows into the tank body and permeates into soil through the small holes.
