Flood-fighting special bag

Abstract

The invention relates to a flood-fighting special bag, able to be used to fill and close up dike breach and piping place and also to be used as temporary reinforcing sub-dike for a weaker dike in flood seasons, and having good filling and closing effect and also able to be used as emergency lifeboat, and comprising a material storage bag in the middle to carry closing fillings and an air bag on two sides of the material storage bag to expand after charged, where the material storage bag and air bag are made of flexible waterproof material, the upper side of the material storage bag is provided with a feed inlet / outlet able to be opened and closed, and the outside of the storage bag is provided with a fixed rope; and the air bag is provided with an air inlet. As the flood falls, it only needs to discharge the air from the air bag and pour out the fillings, so as to be able to be recovered, convenient to recover and save manpower, material resources, and financial resources, especially able to race against the most valuable time for food fighting and relief providing.

Description

technical field [0001] The invention relates to a flood-resisting special bag used for blocking the breach of a dam or a pipe surge during a flood. Background technique [0002] When the flood caused the dam to burst, the usual measures were to manually transport the sacks containing the filling materials to the dam of the breach for filling. This method has many inconveniences: the first is that a large number of heavy sacks are required In order to fill the gap, it is not only difficult to transport, but also consumes a lot of manpower and material resources, and the blocking speed is slow and the efficiency is low; the second is that the sacks filled at the breach of the embankment are easy to be washed away by water, and the sacks themselves are often unable to bear. The third is that after the flood recedes, it will cost a lot of manpower, material resources and time to transport away the sacks used to fill up the embankment. On the other hand, when the embankment has ...

[0002] When the flood caused the dam to burst, the usual measures were to manually transport the sacks containing the filling materials to the dam of the breach for filling. This method has many inconveniences: the first is that a large number of heavy sacks are required In order to fill the gap, it is not only difficult to transport, but also consumes a lot of manpower and material resources, and the blocking speed is slow and the efficiency is low; the second is that the sacks filled at the breach of the embankment are easy to be washed away by water, and the sacks themselves are often unable to bear. Third, when the flood subsides, it will also take a lot of manpower, material resources and time to transport away the sacks used to fill the embankment

On the other hand, when the embankment has not yet broken, but only piping occurs (that is, a local gap appears in the middle of the embankment), it is difficult for ordinary gunny bags to be stuffed into the gap for filling. The remaining gaps will cause water leakage, which will affect the effect of plugging

Existing a kind of patent No. is 03255694 airbag type water-gas emergency leak plugging bag at present, and it is made of the airbag bag that has connecting edge on the periphery, when piping occurs, after the airbag bag is inserted in the piping outlet, the airbag bag Filling with air or water can quickly block the pipe spout, but this device is not ideal for filling the dam breach (in order to withstand the pressure of the flood and prevent it from being washed away by the flood, a relatively heavy filling material is required), so the use of Has certain limitations, and its function is relatively single
