Discuss the reinforcement gabion ( retaining wall and flower beds benches , etc

reinforced gabion is used a lot of areas in the landscape, from the first gabion retaining walls, flower beds to the stone cage, and now used as the basis of stone benches. Its low cost, easy construction, and natural ecology.

practices reinforced gabion is simple, but for landscape stone cage area but not a relative standard practice

gabion Overview Gabion erosion force generally applied for the strong, fast flow of the stream, and high rainfall, high water table of the riparian areas, may also use the structure of the high permeability to facilitate drainage. In addition, the riparian zone of the soil with its settlement, or settlement of a large number of concerns, may also use their flexible nature of the structure to resist large deformation. Taiwan streams steep slope, velocity, usually Hefang the main structures are rigid structures, since the Public Works Committee to vigorously promote ecological engineering methods, not new or repair levee bank protection, most of the quarry cage type facilities have changed for. The preparation of the metal wire gabion in accordance with international standards should be galvanized in their appearance and then wrapped PVC (polyvinyl chloride) pipe material in order to achieve high tensile strength, high corrosion resistance, good deformability and easy to disperse and other requirements. The filling material stone cage should have high hardness wind resistance, not easily broken and hard to corrosion and other features, the average stone size to 20cm ~ 30cm the best. Gabion structure can be divided into gravity (gravity) or semi-gravity type (semi-gravity), the traditional gravity Operators can work structure debris gravity (earth structure) analysis, and half who are heavily dependent on gravity gabion box network itself can provide the resistance, it can be considered as stiffening the structure type of earth and rock work. Gravity or semi-gravity gabion bank protection, according to their surface or in the shore shore step back by design, can be divided into shore side stepped (stepped front face) or back sides stepped (stepped rear face) gabion revetment. Embankment height greater than 3m, the structure should be made after dumping at least 6 ° (α6 °), or the use of shore side stepped gabion bank protection in order to obtain the most economical design. The design of gabion revetment determine the appropriate mainly in the aspect ratio and the type used generally small embankment height, must consider the requirements of aesthetics and appearance, can be used semi-gravity or the sides stepped back (smooth shore side) gabion revetment, and a small part of the shore with tilt angle (α = 6 °); if more than 5 meters high wall, then the recommended surface gravity or the sides stepped design, and supported by the shores of considerable inclination angle (α> 6 °), in order to obtain economic security design.
reinforced stone cage, with a diameter of 8 can be reinforced, galvanized or cement surface can be stained, the grid size of 200 * 150 * 150 or 200 can be, afraid of being squeezed deformation, then pull the wall which can be set bars, stones, custom size, base with concrete, set the expansion joints every 20m.
