Description

Riverbed withdrawal horizontal and vertical tunnel device and method {Apparatus and method for gathering river bed water}

The present invention relates to a riverbed intake apparatus and method, and more particularly, to a device for stably collecting high-quality purified water using a riverbed bottom tunnel and vertical horizontal shaft from a water intake source such as a valley, a river, a river, a dam and a reservoir. And method.

Recently, the shortage of water due to population growth and environmental pollution is intensifying. To solve this problem, the development of new water sources and the efficiency of water treatment are emphasized as important tasks.

Normally, tap water is provided as drinking water after being physicochemically treated in a water purification plant using raw water such as rivers, rivers, lakes and dams as raw water.

However, as the environmental pollution progresses, the water quality of raw water also tends to deteriorate, and although many investments are made, such as advanced treatment, the reality is that the people still have low confidence in tap water.

In addition, although water consumption is increasing due to industrial development and improved living standards, some local cities do not have large reservoirs or rivers where water is easily secured, and it is difficult to secure water supply. The demand for water is also on the rise, and riverside filtered water purification plants are on the rise.

However, in the case of such a water purification facility, there is a problem in that it is difficult to apply practically because there is an economic disadvantage such as high equipment cost and excessive operating cost.

For example, drinking water supplied through tap water is supplied to a user by purifying and filtering the water taken in a predetermined place.

Such water purification and filtration facilities are equipped with a water intake device for water intake, and such a water intake device excavates underground and installs a water intake pipe, and then uses a pump or the like to collect water from a mountain valley. After forming a predetermined water intake space by filling it with a filter medium such as gravel and sand, there is a method of water intake to connect the pipe through the bottom of the water intake.

However, these intake facilities are inadequate to be used as drinking water supplied with muddy water due to the inflow of muddy water during the rainy season with heavy rainfall, and most of all, there is a lack of water in the future to traverse the river to trap water like the Four Major Rivers Project. When the beam is installed, the water can be retained (secured), but it is difficult to secure a large amount of stable and good quality water, such as that the water quality may deteriorate compared to the relatively flowing water.

Accordingly, the present invention has been devised in view of the above, and the construction of various intake tunnels according to the location of intake sources such as valleys, rivers, rivers, dams and reservoirs, and the large intake pipes around the intake tunnels By constructing a new type of water intake system to collect water from the riverbed by constructing a small filtration pipe, etc. There is a purpose.

A casing fixedly supported on the surface and filled with sand therein, and arranged concentrically in the inner center of the casing, and having a lower end penetrating through the intake tunnel and extending to the inside of the tunnel to purify purified water. It consists of carbon perforated pipes that lead to It is characterized by being able to take water roughly.

In addition, another example of the riverbed intake horizontal and vertical tunnel device provided by the present invention to achieve the above object is a device for taking in the best water quality in a large amount, the horizontal construction along the riverbed in the basement of the bottom of the water intake source, worker or perforated Tunnels having a diameter enough to fit the equipment, intake pipes installed side by side along the interior of the tunnel, radially extending from the intake pipes through the tunnel to the lower bed, the upper end is in contact with the lower bed It has a structure in communication with the intake pipe and includes a plurality of carbon perforated pipes to guide the purified water to the inside of the intake pipe, it is characterized in that it is possible to reliably roughly intake the naturally purified water.
