TH68092A - Guidelines for flood control and drainage - Google Patents

Abstract

DC60.This invention revealed a simple and easy method for flood control and with High drainage capacity The invention is a means of speeding up the drainage capacity of a river into the sea through a range of water. Up and down naturally Look like this Able to achieve results By offering the following techniques Establishment of the PTCCG between the inlet tidal limit and the coastal tangent or section Narrower than that of the microclimate; In theory PTCCG should It has been built across the river from the shore when there is danger of flooding during That flood season We can close PTCCG and prevent tidal currents entering the river when the tides are reduced. We are able to open PTCC. G again and drain the clean water stored into the sea. Usually the PTCCG is opened when not in use. This invention can bring Applicable to all microphones This PTCCG uses a natural tidal range to To control the floods in the upper streams of the river This PTCCG has Tremendous flood control ability And accelerate the speed of draining that floods into the sea.This invention reveals a simple and easy way to control floods and by having High drainage capacity The invention is a means of speeding up the drainage capacity of a river into the sea through a range of water. Up and down naturally Look like this Able to achieve results By offering the following techniques Establishment of the PTCCG between the inlet tidal limit and the coastal tangent or section Narrower than that of the microclimate; In theory PTCCG should It has been built across the river from the bank when there is danger of flooding in During the flooding season We can close PTCCG and prevent tidal currents entering the river when the tides are reduced. We are able to open PTCC. G again and drain the water. PTCCG is normally opened when not in use. This invention can be applied to all microclimate. This PTCCG uses a natural tidal range to To control the flood in the trunk Upper river water This PTCCG has Tremendous flood control ability And accelerate Of the drainage that floods into the sea

Claims (5)

1. Methods for flood control and flood drainage, including: a. Establishment of the PTCCG at a specific area within the limit. Limiting tides and between The narrower part of the estuary and / or the tangent of the estuary. And the PTCCG should be built across the river b. Shutting down the PTCCG when there is a danger of flooding in the flood season. Which is to prevent the current The tidal flow enters the inner part of the river, the re-opening of the PTCCG when the tide recedes and the flooded drainage that is stored into the sea. C. TCCG will be opened when not in use. 2. According to Clause 1 above, a unique feature is that PTCCG is able to receive Built in the narrower part of the estuary 3. According to Clause 1 above, the special feature is that P. TCCG may have been built. Up from different types of gates, such as a smooth, multi-sectional water gate 4. According to claim 1 above, a special feature is that the spread of the PTCCG covering This covering can range from 20 percent ~ 80 percent of the width of the narrower part of the microclimate. 5. According to Clause 1 above, the special feature is that during the flood season and when there is danger from flooding, the period of use of PTCCG is approximately 7 ~ 14 days.
