  The leakage proof expansion bag is mainly used as flood control materials, and the special water absorption expansion bag for flood control
The expansion material in the bag is water, which does not need to excavate and transport soil, sand and stone, saves a lot of manpower, materials and transportation, and is conducive to environmental protection and ecology; In the lack of sand, stone and soil sources, its advantages are particularly prominent
It has the advantages of fast operation, high efficiency and fast speed
It can quickly rescue in case of critical emergency flood control
3
During flood control, there are no equipment requirements, complex technology and simple operation
Compared with the flood control bag filled with sediment, the investment of human and material resources is greatly reduced
One bag is multi-purpose, retaining water, seepage and preventing waves, which can effectively protect the dam

The polymer water retaining agent pre installed in the bag is a new environmental protection material, non-toxic, tasteless and pollution-free

The bag before water fixation is light in weight and small in volume, and can carry dozens of bags per person
Sealed packaging for easy storage
Application scope of water absorption expansion bag:
(I) prevention of Dam Landslide: when the dam is affected by water seepage and causes landslide, if it is not stopped in time, there will be the risk of dam collapse

Specific use method: use the water absorption expansion bag at the lower part of the embankment sliding embankment according to & ldquo; Product & rdquo; The zigzag is stacked in multiple layers to prevent the dam soil from continuing to slide in Zui a short time, and at the same time, it can speed up the time to fill the earth and rush to repair the collapsed dam

(II) dam elevation: according to the water regime forecast, the flood level will exceed the design flood level and may even exceed the dam
Before the flood comes, use a suction bag to repair the sub dam on the side facing the water on the top of the dam to prevent overflow

Specific use method: after the water absorption bag expands, build it in layers and press it tightly
In order to avoid interlayer leakage, loose soil should be added between layers
If it can be used with plastic film, the anti-seepage effect will be better
