Alternatives sandbags for flooding to prevent basement storm

Overview of the Development, Promotion and Application of "Water Blocking" Flood Control and Disaster Relief Water Absorption and Expansion Bags [also called Rapid Expansion and Leakage Stopping Bags] - Instant sandbag and self-inflating sandbag.



In the past, there have been phenomena such as slow rescue speed, high difficulty, high manpower usage, high investment, and unclear effectiveness in flood control engineering rescue, which have caused significant losses to flood control engineering. To solve the above problems, a flood prevention and rescue special "water blocking" flood prevention and disaster relief water absorption and expansion bag with simple operation, convenient carrying, fast expansion speed when encountering water, and fast weight increase is available. It can be widely used in flood prevention, rescue, dike loopholes, overflow rescue, temporary elevation of flood control dams, construction of temporary waterproof walls, slope protection and erosion prevention, Engineering closure, blockage of underground ditches and tunnels, etc.




The rapid expansion leak stoppage bag - spill control sandbags is a non-toxic, tasteless, non melting, difficult burning polymer artificially synthesized with "super absorbent resin", which has high water absorption. The expansion agent is packed in an outer bag made of non-woven fabric with good water permeability. When contacting with water, the resin swells and gelatinizes in a short time, Rapid expansion of volume and rapid increase in weight, The expansion speed of the expansion bag reaches the maximum expansion volume in 2-3 minutes, which can reach 80-100 times the original volume. Based on the characteristics of small volume, light weight, convenient carrying, and rapid expansion of the expansion bag in flood prevention and rescue before encountering water, we conducted two experiments to compare it with embankment leakage blocking and cofferdam closure.
