Abstract

PURPOSE:To prevent the intrusion of foreign matters into the air supply and discharge systems by a method in which the inside of the film dam is provided with a partition wall to divide it into two compartments vertically, an air supply tube is connected to the upper compartment, and the lower compartment is connected with the upstream side of the film dam through an opening. CONSTITUTION:The inside of a rubber dam 1 is divided into upper and lower compartments 3 and 4 by a partition wall 2, an air supply tube 13 from which air is supplyed or discharged is connected to the upper compartment 3, and an exhaust pipe 15 with an exhaust valve 16 on the tip of its mid-branched portion is provided to the pipe 13. The lower compartment 4 is provided with another opening 25 connected to a drain pipe 26 with a drain valve 27. When raising the rubber dam 1, the exhaust pipe 16 and the drain valve 27 are closed and air is charged into the dam 1 through the compartment 3 by means of the blower 14. Also, when falling down the dam 1, the exhaust valve 16 and the drain valve 27 are both opened manually. By this, the intrusion of foreign matters, e.g., water, soil, sand, etc., into the air supply and discharge systems can be completely prevented.

[Detailed Description of the Invention] This invention relates to a flexible membrane weir, and in particular, the weir height is adjusted by raising the weir by supplying air and allowing water to enter while discharging the air. Regarding membrane weirs.

Flexible membrane weirs, commonly referred to as rubber weirs, which expand or contract when fluids such as air or water are injected or discharged, are easy to construct and inexpensive, and are useful for agricultural water intake and seawater damming at estuaries. It is becoming widely used. These membrane weirs are roughly divided into air type and water type depending on the type of fluid enclosed. The pneumatic type does not require a water tank to store the incoming liquid, has less friction loss to the supply and exhaust pipes during injection and discharge, and has a small mass, so it is cheaper and takes less time to drain and supply water than the liquid type. It has the advantage of being short.

However, the pneumatic membrane weir has a drawback in that a V-shaped notch is formed between the membrane weir main body in the middle and the inclined parts on both sides along the slope. In order to compensate for this drawback, a hybrid or semi-aqueous membrane weir has been proposed in which water is partially allowed to enter the pneumatic membrane weir. By opening the bottom of the membrane dam to the upstream side in a compromise system such as this, a water tank and water injection pump are not required, and an increase in cost can be prevented.

'However, in such a semi-water type membrane weir, water enters as air is discharged, increasing the amount of water inside the membrane weir. There is a danger that this water may enter the air supply and exhaust pipes and even reach the blower, damaging the book. In addition, water and dirt and foreign matter enter the membrane weir, and this deposits at the bottom of the membrane weir or floats on the water surface. In extreme cases, there is a problem that foreign matter may enter the supply/exhaust pipe 5 and cause the supply/exhaust valve to malfunction.

The present invention is a flexible membrane weir that eliminates these drawbacks.
In a flexible membrane weir that rises when fluid is injected and collapses when fluid is discharged, a partition wall is provided within the membrane weir to partition the interior into two upper and lower spaces, and a constriction pipe is installed in the space above the partition wall. This relates to a flexible membrane weir characterized in that when connected, the lower space is communicated with the upstream side of the membrane weir through an opening, and its purpose is to:
The purpose is to prevent water and foreign matter from entering air supply and exhaust systems such as supply and exhaust pipes and valves.

As mentioned above, this invention has two partitions inside the membrane weir, one above and below, by a partition wall.
Since the lower space is connected to the upstream side of the membrane weir through an opening, water is prevented from entering the upper space by the partition wall. Therefore, water or foreign matter will not enter the air supply/exhaust system connected to the upper space. Therefore, it is possible to provide a highly reliable flexible membrane dam without causing the prower or the supply/exhaust valve to become inoperable due to water or foreign matter.

As described above, the rubber ring 1 is raised and collapsed, and in this case, the upper space 3 and the lower space 4 of the rubber ring 1 are completely partitioned by the partition wall 2.
Therefore, water does not enter the upper space 3. Therefore, water is completely prevented from entering the supply/exhaust pipe 13 and furthermore reaching the blower 14. Also, dirt and foreign matter that have entered the rubber dam along with water 1 are blocked by the partition wall 2 and do not reach the air supply and exhaust system. Therefore, the supply and exhaust system is activated.
It doesn't make you incapacitated.
