Dropper guardrail based on communicating vessel principle

Abstract

The invention discloses a dropper guardrail based on the communicating vessel principle. The dropper guardrail comprises a guardrail body, a water storage stand column I and a water storage stand column II. The water storage stand column I and the water storage stand column II are arranged on the two sides of the guardrail body in the length direction respectively. The water storage stand column I is provided with a water storage cavity I and a balance cavity I. The balance cavity I is communicated with the external environment through a balance hole I. The water storage stand column II is provided with a water storage cavity II and a balance cavity II, and the balance cavity II is communicated with the external environment through a balance hole II. The guardrail body is provided with a water pipe for communicating the water storage cavity I with the water storage cavity II, and the water pipe is connected with a drip irrigation head capable of being controlled to be opened and closed; the water injection pipe is arranged on the water storage stand column I and / or the water storage stand column II; the water injection pipe is provided with a water injection port communicated to the water pipe; the drip irrigation guardrail can be improved, the water storage function is achieved, meanwhile, effective drip irrigation can be achieved when the water level is low, warning is conducted when the water level is low, water injection is conducted in time, and continuous and effective irrigation for greening is achieved.

Description

technical field [0001] The invention relates to the field of road greening and irrigation, in particular to a dropper guardrail based on the principle of a communicating device. Background technique [0002] There are often artificial green lawns beside urban roads, and it is necessary to hire a special person for watering. In order to save manpower, the ground water pipes for watering are often buried underground, and then the water pipes are turned on regularly for watering. This method has a disadvantage: maintenance is difficult, and the water pipes are damaged. It is not easy to find; there is also a common equipment guardrail next to the road, which has a single function and mainly prevents traffic accidents caused by vehicles and people rushing to the road. [0003] In the prior art, the patent of Patent Bulletin No. CN2383881 discloses a road greening drip irrigation guardrail, which is composed of concrete piles, guardrail metal frames, and drip irrigation pipes.

Problems solved by technology

[0002] There are often artificial green grasslands next to urban roads, and it is necessary to hire a special person to water them. In order to save manpower, the ground water pipes for irrigation are often buried underground, and then the water pipes are turned on regularly for watering. This method has a disadvantage: maintenance is difficult, and the water pipes are damaged. It is not easy to find; there is also a commonly used equipment guardrail beside the road, which has a single function and mainly prevents traffic accidents caused by vehicles and people grabbing the road

[0003] In the prior art, the patent of patent notification number CN2383881 discloses a road greening drip irrigation guardrail, which is composed of concrete piles, guardrail metal frames, and drip irrigation water pipes. There are holes on the concrete piles that can pass through the drip irrigation water pipes, and the drip irrigation water pipes are installed through the holes. On the concrete piles, the guardrail metal frame is also installed on the concrete piles, and there are drip irrigation heads on the water pipes; therefore, this scheme can not only prevent vehicles and people from grabbing the road, play a role in diverting traffic, reduce the occurrence of traffic accidents, but also Drip irrigation can be carried out on the green land, killing two birds with one stone; the above-mentioned technical solution solves the problems in the prior art to a certain extent, but in actual use, it has no water storage function, and it needs to be connected to the water source to perform drip irrigation, and there is a problem when the water level is low. Insufficient pressure and thus unable to carry out effective drip irrigation
