Integrated Drain Gate Seawall System

Abstract

The Integrated Drain Gate Seawall System (IDGSS) was designed to mitigate flooding due to rising sea water, severe rain and storm damages at costal area or other various waterfront properties like riverbanks, bay, beach, ocean, lake, marsh and low lying areas. The IDGSS has incorporated two functions simultaneously by separating water and land with a flood resilient fixed water barrier wall, but more importantly, has an automatic drainage system, especially for an unexpected severe and prolonged storms; to address the unintended consequence of trapping water inside the pre-existing water barrier walls. Unfortunately, during these severe storms, the trapped water has created a bathtub like scenario by the manmade fixed wall barriers, and causing an insult to an injury to an already devastated storm conditions, due to a lack of drainage systems. To mitigate this type of severe drainage problem, IDGSS was created with a characteristics of a concrete wall blocks, which includes a one-way valve or flap drain gate inside as a single unified structure, with an adjustable one-way valve or flap drain gate specification; with a various shape, sizes, materials and configurations for both one-way valve or flap gate and wall blocks; and adaptable retrofitting mechanisms to meet the site specific topography and special drainage needs. To protect the one-way valve or flap gate drainage system and to allow for an efficient drainage pathway system, the wall blocks are built to withstand severe wind and unpredictable weather conditions to become storm resilient, pressure reducing mechanism within the unlimited combinations of geometrical wall shape and size arrangements. Thus, the IDGSS is a reinforced wall system that can adapt to a specific drainage problem by allowing the trapped water to be returned back to where it came from as long as the water recedes by gravity.

The invention claimed is: 
     
         1 . An Integrated Drain Gate Seawall System (IDGSS) wall structure for protecting land or low-lying, marsh area inside the water barrier wall from flooding like a bathtub by the bodies of trapped water coming from above, side and below like severe rain, splashing storm surge and storm drainage backup, comprising:
 a. A wave, wind, water pressure force blocking barrier wall(s) and/or column block placed between the bodies of water and land/marsh.   b. An integrated including one-way valve or flap drainage gate placed facing the land or low-lying, marsh area with gravity, hydrostatic pressure operated   c. At least 2 or more grid screens; one inside, placed in front of the flap drain gate facing the land, others are facing near the bodies of water where trapped water will exist.   d. An emergency shut-off door placed towards the wall facing near the land or marsh.   
     
     
         2 . The IDGSS construction of  claim 1  in which water barrier walls and columns comprising plurality of wall block units, wall facing shapes, configurations, shapes, size, material, arrangements and geometric combinational formations between the lateral and adjacent walls. 
     
     
         3 . The IDGSS construction of  claim 2  in which water barrier walls and columns comprising plurality of meeting the existing walls, topography and project site specific location. 
     
     
         4 . The IDGSS construction of  claim 1  comprising a plurality of flap drainage gate unit, shape, size, material and design. 
     
     
         5 . The IDGSS construction of  claim 1  comprising a plurality of grid screen units, configurations, shapes, size, material and design. 
     
     
         6 . The IDGSS construction of  claim 1  comprising a plurality of emergency shut-off door unit, shape, size, material and design. 
     
     
         7 . A IDGSS method for protecting land or low-lying, marsh area inside the water barrier wall from flooding like a bathtub by the bodies of trapped water coming from above, side and below like severe rain, splashing storm surge and storm drainage backup, comprising
 a. Providing a customized wave, wind, water pressure blocking barrier wall(s) and/or column(s) to protect the one-way valve or flap gate system and to provide drainage as the wall guides the trapped water laterally as it exits automatically from the bathtub to the water outside like the sea or where it came from. When the water level is higher inside the wall than the level outside of the wall, the one-way valve or flap gate will open by itself and begin to drain.   b. Providing a customized configuration of the geometrical shape wall blocks that meets the not only for new constructions, but an existing walls or topography.   c. Providing a customized wave, wind, water pressure blocking barrier wall(s) to protect the site specific one-way valve or flap gate drainage system project.   d. Providing an IDGSS as needed by retrofitting the existing wall(s), or added on at a later time to meet further drainage needs due to climate changes and overflow drainage needs, or as a proactive measure to mitigate flooding
