US 2002/0157583 A1 · METHOD AND DEVICES FOR FORESTATION AND FLOOD PREVENTION

Abstract

With the present invention, sand storm disasters will no longer occur in Beijin and the Hubui province in China and the water of the Yellow River will be clear; soil erosion due to flood in the United States and Europe will decrease. The invention utilizes the sand, soil and gravel of the earth to cure its illness. Such normally useless natural materials are filled in plastic bags to form flexible soft sand bricks, and they are laid on the ground to stabilize sand for growing vegetation or to prevent soil depletion due to water erosion. With the present method, sand and soil are stabilized to the condition similar to that grass has already grown on them for five years and trees have already grown in them for ten years. It can thus be used surely for carrying out forestation all over the world; forestation may even be carried out in barren area in the United States so as to have rich forests throughout the country; and the area around the Wufoo water dam will recover to its past beauty. The tree planting bullet of this invention may be used with planting guns firing them from the air or with water guns firing them on land to facilitate tree planting, such that corporations in the forest industry will no longer hesitate to carry out reforestation in regions destroyed by forest fires, due to the devaluation of their company shares. The invention may be used to change the environment of the Middle East to favorable for living so that it may have ever lasting peace. The soft sand bricks of the present invention may be used to grow vegetation in the desert for conquering the normal difficulty in its forestation. Forestation is important since it can mitigate flood disaster, drought, and sand storm in the desert; and it can be realized inexpensively with the use of the soft sand bricks and the planting bullets of the present invention. Therefore, it can prevent the further deterioration of the earth. The countries and regions indicated above are for illustration only.

Dependent claims

In order to maintain the existence of the earth, the land must coexist with vegetation to maintain its stability. The characteristics of the invention includes:

Using thin sheet plastic bags to hold sand, soil and gravel to make a building material, i.e. soft sand and soil bricks, in cube shape, elongated shape, or large rectangular shape for protecting and stabilizing the ground and for saving water in the ground.
The soft bricks are fabricated with vacuum packing, or seal packing, and opening are formed in the package.
The machine for making the soft sand bricks has means for wrapping a continuous belt of plastic sheet into various shapes to form bags at a station which includes filling the bags with sand and gravel and heat sealing them. It includes using a single roll of plastic sheet which has a series of bag openings and connected together to form a continuous belt It also may feed a flat belt, in a flowing water manner, through a shape forming tube to form and seal the belt into an elongated round tube after placing sand from its left and right sides.
The machine has a device for filling the bags with sand, soil and gravel and it has an electrically controlled device for heat sealing the plastic bags
The above described tree planting process includes the following special characteristics:
using gun bullet heads having tree seeds or seedling enclosed in them.
using a sealed or tent like housing with breathing provisions or an opened housing to grow tree. Vegetation may also be grown in a trench with the lower portion of the housing extending into the trench. Optical fiber is used for conducting sun light to underground trench or hole.

4 more elements

A system according to claim 1 including a sealed plastic tent-like housing normally maintain in an upstanding erected condition by supporting rods. Sand is provided at the bottom of the housing for anchoring it on the ground and the interior of the housing is used for growing a plant. A first opening is formed at the top of the housing for admitting air into the housing when wind blows across this first opening. Reverse air flow preventing means is provided at this first opening. A second opening is formed at the top of the housing to provide another breathing opening which operates to expel air from the housing when the housing is subject to outside pressure. Reverse air flow preventing means is also provided in this second opening. An third opening is formed in the housing which communicate with a water storage tank provided outside the housing. A floatable ball valve controls the flow of water from the water storage tank through this third opening into the housing for feeding the plant.

A system according to claim 19 including two wings mounted adjacent to the first opening operated by outside wind for drawing outside air into the housing, an inlet air control valve coupled to the first opening by an air duct, an air balloon located in said duct, and the air balloon being connected to an evaporation dish located in the housing, the air balloon being operative by the vapor generated from the evaporation dish to block the air duct when outside air is hot during the day time, also a steel ball being located in the air duct and being operative to block the air duct when too large amount of air is flowing through the air duct.
