Geomembrane bag is to use a double polymer chemical fiber made from synthetic materials (or individual) consecutive packaged products. Geosynthetic materials used in engineering is nearly 20 years developed a new technology, in the late seventys to introduce and use in our country. Membrane bag concrete by using high-pressure pump when pouring concrete or cement mortar into the membrane bag, the thickness of the concrete or cement mortar through bag bag, hoisting steel rope (polymers such as nylon, etc.) to control, the length of the concrete or cement mortar has certain intensity plate structure is formed after consolidation, or other structure, can meet the needs of the project. Geomem brane bag as a kind of new building materials, can be widely used in river, lake and sea embankment slope protection, revetment, harbor, dock and other protective engineering.

Membrane bags advantages

(1) geomembrane bag construction is made of a sprinkler irrigation forming, construction is simple, fast,

(2) geomembrane bag can adapt to various complicated terrain, especially in the deep revetment and bottom protection, do not need to fill cof- ferdam, can be directly underwater construction, high mechanization degree, slope protection by the large surface area, strong integrity, good stability, lang service life.

(3) geomembrane bag has certain permeability, after the pumping concrete or cement mortar, leakage, excess water through the fabric gap can be quickly reduce the water cement ratio, speed up the setting rate of concrete, increase the compressive strength of concrete.
