一、Material Description：

    Geotextile is a good filter material, and has the functions of resistance to brushing, erosion and soil reinforcement. Geotextile with appropriate opening rate can provide penetration of plant rhizomes and form a surface layer of vegetative greening. It is a multifunctional earth material with mechanical stability, water conservancy brushing and vegetation greening. The sausage material is a high-tensile fiber permeable tubular belt woven from geosynthetics. The main component of the fiber is polypropylene permeable fabric. The bag body is unfolded on site and then connected to the hydraulic conveying pipeline to fill the dredged sediment, can be used as berm, breakwater, spur and slope protection. The sand intestine pipe is a bag body with both water permeability and soil retention. After hydraulic filling, the water in the bag body is quickly removed and retained in the internal soil to become a stable geotextile and soil complex. The project can play a great environmental benefit.

       Slope remediation, Marine engineering,Landscape engineering,

       Water conservancy project will be widely used.

二、Product Features：

    There are also a series of large-scale tests outside the house of the ground sand intestines. The ground sand intestines can be used as dredging and dehydration facilities for river dredging. At the same time, the loading test of the sand intestines is carried out to confirm the animal force of the sand intestines in the stacked state. The concept of balance developed a model for predicting membrane tension of the sausage intestine. The ground sand intestine can also be used in reclamation to build cofferdams. The sand pumping material from the sea is used to fill the ground sand intestine pipe as a berm. The ground sand intestine pipe is both a water permeable and soil-reserving bag. In recent years, the ground sand intestine The practicality of the intestine has been paid more and more attention. It is filled with the soil and sand extracted from the local area, and the water and soil can be retained in the bag, so that the ground sand intestine tube can be combined with the earth to form a stable structure.

三、Practical examples of literature：

 ( 1 ) Pilarczyk (1998), reported the use of sand gutters in coastal engineering, including cofferdams and dykes for dredging mud, offshore dykes, beach maintenance dykes, and slope protection embankment.
( 2 ) Fowler (1997), used ground sand gutters to form cofferdams to accommodate the dredged silt from the Mississippi River, and used ground sand guts as the core material for the elevation of the original river embankment.
( 3 ) In 1970 , the US Army Corps of Engineers used ground sand intestines to fill sand and soil in Texas . As the role of slope and wave breaking , ground sand intestines were used in important projects to replace traditional materials such as concrete and asphalt.
( 4 ) The land reclamation project of Liuqing Outlying

Island Industrial Zone, Yunlin County, Taiwan, because the land used for the entire industrial zone is too large and Taiwan itself lacks land, so it competes with the sea for land and creates a sea kingdom enterprise.
