A farmland irrigation and drainage system includes: a water inlet pool, the water inlet pool being provided in a piece of farmland, and the water inlet pool being made with a water-filtering material; and, a water outlet pool, the water outlet pool being provided at an interval to the water inlet pool in the farmland, a water overflow being provided on the sidewall of the water outlet pool The water outlet pool is communication with the farmland via the water overflow, and a predetermined water level of the farmland is controlled by controlling the height of the water overflow. The technical solution of the present application solves the problem that automatic irrigation and drainage could not be implemented by a farmland irrigation and drainage system in prior approaches.

A subsurface irrigation system for a sports field includes a substantially water impermeable layer, a compacted subgrade below the water impermeable layer, a plurality of water distribution boards positioned on top of the water impermeable layer, a porous layer overlaying the plurality of water distribution boards, and a sports field layer on top of the porous layer. The porous layer is configured to move water from the plurality of water distribution boards upwards to the sports field layer using capillary action to keep it damp. The sports field layer may be sand, dirt, clay, or a combination thereof. In addition, the system may include a water control basin in fluid communication with at least one water distribution board of the plurality of water distribution boards and configured to control the flow of water to the plurality of water distribution boards.

The present invention relates to a water resource utilization structure that collects and stores water resources penetrating the ground, such as rainwater or melted snow, and distributes and utilizes the stored water resources for various purposes such as housing, vegetation, trees, industry, and fire. 1. It is a structure that utilizes water resources to respond to global environmental disasters and climate change with a focus on water circulation, water storage, and water supply. 2. In other words, it is a water resource utilization structure for sustainable green growth in response to global climate change.

A water retention assembly for retaining water around a plant includes a barrier that includes a first ring portion integrated into to a second ring portion. The first ring portion can be inserted into ground having the second ring portion surrounding a plant. The barrier is comprised of a fluid impermeable material to retain water around the plant when the plant is watered. Additionally, the barrier has a feed passage extending therethrough to accommodate a supply pipe of a water drip system. In this way to the water drip system can automatically water the plant surrounded by the second ring portion.

A soil irrigation and restoration system comprises a water transmitting device having a water containing tank, a water pumping element, and a pipe. The water containing tank has a containing space formed therein. The water pumping element is disposed in the containing space and has at least one water inlet, a water outlet, and an overflow portion. The water outlet is spaced apart from the at least one water inlet. The overflow portion is disposed between the at least one water inlet and the water outlet, and is disposed at a position higher than that of the at least one water inlet and the water outlet. The pipe has a connecting end connected to the water outlet. A portion of the pipe away from the connecting end extends downwardly and is buried in the soil layer. A soil irrigation and restoration method executed with syphon effect is also provided.

A lawn sprinkler head protector that is made with a hardened concrete material. The shape of the sprinkler protector creates a housing for the sprinkler head to reside in. The hardened concrete material provides the proper weight for the sprinkler head protector to not be dug up out of the ground by a dog. The round shape of the sprinkler head protector is made in a polymer cast. This round shape makes it more difficult for a dog to dig up when buried in dirt.

An object of the present invention is to provide a layer for suppressing permeation of soil moisture that has a low environmental load and can be easily constructed, and a method of forming the same. The method of forming a layer for suppressing permeation of soil moisture comprises a step of spraying coagulant for a natural rubber latex over a target soil and then spraying a natural rubber latex over the target soil, and repeating the step twice or more.

The present invention provides a water-retaining layer for retaining water in soil, the water-retaining layer being composed of a coagulated natural rubber latex; a greening system having the water-retaining layer provided; and a construction method of the greening system, comprising: an exposing step of removing surface soil in a construction target land and exposing underground soil, a spraying step of spraying a natural rubber latex on an exposed surface of soil, a coagulation step of coagulating the natural rubber latex to form a water-retaining layer, and a covering step of covering the water-retaining layer with the removed surface soil.
