Description

[0001] Drainage Device Having Front Waterproof Wall [

The present invention relates to a concrete drainage pipe having a front catchment, and more particularly, to control drainage amount or water level according to necessity or rice growing condition, Which can prevent a hole or the like from being pierced through the front surface of a concrete drainage pipe.

Generally, when a farmhouse needs to dry a rice field or a rice paddy when it is necessary to dry rice paddies, a rice paddle is shoveled to drain the water in the rice paddy so that it becomes drainage. When the drainage is completed and the rice paddy is no longer necessary, I have been repeating how to recover.

This conventional method is often accompanied by a waste of water caused by the neglect of management and the collapse of the restored rice paddies, and the difficulty of aging rural manpower is increasing.

Therefore, in order to solve these problems, a water pipe made of plastic or the like has been installed in a rice paddy field, but it has not been robust and has a short life after being installed in a lightweight structure.

In addition, there was a lot of difficulty in achieving the purpose of the watercraft installation, as the watercress around the watercount had been pierced with holes made of crab or cowl and the watercress around them had to be repaired.

The patent documents which are the background of the invention disclose a method for controlling water level from paddy fields or preventing the escape of crabs or snails.

In the case of Patent Document 1, the length of the bottom of the rice paddle can be adjusted according to the width of the rice paddy, and a floating paddle having a simple supporting plate of a narrow size is inserted and detached. However, in the case of Patent Literature 1, it can not be used at all when the width of the rice paddle is larger than the maximum length of the maximum length of the paddy pipe extending the flow channel, and the pipe connection shape for further joining the drain pipe of the drain pipe, ), There is a disadvantage that it is very difficult to apply to an actual rice field.

The watercock of Patent Document 2 has a configuration in which a catchment film is assembled and attached to the side and bottom surface of the body, but it is disadvantageous in that it can be installed only by the installation method corresponding to the watercourse, and the construction is somewhat difficult.

In addition, the watercraft body of Patent Document 2 has a step protruded so as to have the same width and height along a center line crossing the right and left sides of the side surface of the body, and a concrete structure having a complicated structure There are many difficulties in manufacturing economics due to the demand for a mold. In addition, the aquatic membrane of Patent Document 1 is placed in the inside of the pond as a form simply inserted into the aphospheric membrane inserting groove. However, when the rice paddy containing a large amount of water is collapsed, .

In addition, since the body of the billet of Patent Document 2 is provided with a circular opening formed integrally as a concrete material and a drain port formed integrally with the opening so as to extend vertically outward from the outer surface, It is a very difficult situation in the production economy to make it.

In addition, the drain hole of Patent Document 2 is formed integrally with the body, so that the drain hole can not be detached and attached, and the body itself must be manufactured in accordance with various drain hole standards. Further, the drain hole of Patent Document 2 has a problem in that when the drain hole is partially broken or cracked, the entire body must be separated and reinstalled from the rice paddy.

In addition, although a relatively large size drain hole is required to maximize drainage in case of heavy rainfall, the drain hole of the integrated body of Patent Document 2 is detached from the concrete body and replaced with a large drain hole There is a drawback that can not be.

Further, in the case of Patent Document 2, since the drain hole is formed on the back side of the body, the drain hole around the drain hole is disposed at an excessively downward position from the position of the water hole, or the drain hole is formed right below the water hole It is very difficult to transfer the water that has flowed horizontally out of the watercourse to the drainage pipe. When the pipe member is excessively bent as a separate pipe member is installed for water delivery, water in the watercourse smoothly flows to the drainage channel It is very difficult to make it.

In addition, the water height adjusting plate of Patent Document 2 is inserted into the water height adjusting plate groove extending in the vertical direction in a fitting manner, so that the flow force of the water in the horizontal direction is directly transmitted to the water height adjusting plate, Since the water height adjustment plate is fixed in the water height adjustment plate groove, deformation occurs in the water height adjustment plate, and it is very inconvenient to use the excessive user force when adjusting the water height.
