 2.2 Hebei Five Star Electric Equipment Co., flood control expansion of the bag Cofferdam closure test 
 2.2.1 Closure of expansion of the production of bags 
 Long 65cm wide and 40cm of sacks, the inner sleeve of absorbent non-woven cotton two layers sewn into a rectangular bag containing 150g of high absorbent resin can be. 
 2.2.2 using the method 
 The first flood control expansion bag span the dangerous condition of the place of opening the package, into the water, then remove, laying Cofferdam. 
 2.2.3 The test passed 
 In the tributaries of the Yellow River, the water flow is 17 m wide and 0.5 m deep, flow rate of 150m3 / s, 20 Qiang Hu players use expansion bags, 20 use of traditional soil bags (bags of the same size and expansion). The team first flood control expansion bag came through the test points to open the package into the water, then remove and laying Cofferdam. Yards high layer, layer 2 yards wide, shared the 1120 expansion bag, the water was completely cut blocking. The use of traditional woven installed the Land Reclamation Dam, five players with bags loaded in the point 200 meters from the test soil, and then stacked by 15 players back to the pilot sites, code 6 floors, Layer 2 yards wide, common soil bags 760 , water flow is completely cut-off block. 
 Expansion of the bag 20 players, 10 minutes Cofferdam retaining successful, woven bags of soil 20 players, 90 minutes the Cofferdam retaining success. Trial found that use of Hebei Five Star Electric Equipment Co., flood control expansion of the bag closure Cofferdam than the use of traditional soil bag retaining a simple, easy to save on labor, the most important is to gain time for the rescue, that is, within the same time, traditional methods handle a dangerous situation, Hebei Five Star Electric Equipment Co., flood control expansion of the bag can handle 9 danger, and also to solve the practical difficulties of the traditional soil bags in operation, and general flood season is dangerous in the rainy weather, is full of mud, The soil is very difficult in this case, the use of flood control inflation bags do not have to worry about this situation, this should be widely applied method of water flood.
