Quick-setting concrete prefabricated hollow composite board and application method thereof in flood-fighting and emergency rescue

Abstract

The invention discloses a quick-setting concrete prefabricated hollow composite board and an application method thereof in flood-fighting and emergency rescue. The quick-setting concrete prefabricatedhollow composite board is composed of a water-resistant degradable paper layer, a sodium silicate layer, a calcium oxide layer and a steel reinforcement framework layer, wherein the steel reinforcement framework layer is positioned at the center; the calcium oxide layer wraps the periphery of the steel reinforcement framework layer; the sodium silicate layer wraps the periphery of the calcium oxide layer; and the water-resistant degradable paper layer wraps the periphery of the sodium silicate layer. According to the quick-setting concrete prefabricated hollow composite board and the application method thereof in flood-fighting and emergency rescue, the sodium silicate layer and the calcium oxide layer enable concrete to be quickly solidified in the steel reinforcement framework layer, sothat the concrete is solidified and formed within several minutes in a water environment, certain strength is achieved, a firm concrete protection layer is formed on the water facing surface of a dam, extrusion and scouring of flood to the dam are resisted, collapse and collapse of the dam are prevented, a traditional flood-fighting and emergency rescue mode is changed, the dam is reinforced moresafely and more efficiently in the water environment, water pollution cannot be caused, and the life and property safety of people is protected.

Description

technical field [0001] The invention belongs to practical new materials, and in particular relates to a quick-setting concrete prefabricated hollow composite board and its application method in flood fighting and emergency rescue. Background technique [0002] With the warming of global temperature and the accelerated melting of glaciers, flood disasters often occur in the middle and lower reaches of the Yellow River and Yangtze River in my country, which brings huge losses to the safety of people's lives and property. At present, flood fighting and emergency rescue still adopt the traditional method of covering with water and soil. People use sandbags, straw bags, and wooden piles to block floods. As a last resort, use human platoons to block the water, or throw heavy equipment such as vehicles into the water to prevent the impact of floods. Although this traditional method has all played the effect of blocking the flood, it always feels that half the effort is half the ef...

AI Technical Summary

Problems solved by technology

Although this traditional method has played a role in blocking the flood, I always feel that the result is twice the result with half the effort, and it cannot be permanently regretted.

Moreover, the construction is difficult and dangerous, and the firmness of the embankment is not optimistic
