Ecological bag is an important part of the flexible ecological slope engineering system. The ecological bag has a targeted permeable and impervious filtration function, which can not only prevent the loss of filler (soil and nutrient mixture), but also realize the normal exchange of moisture in the soil, plants can grow freely through the bag body, the root system enters the engineering foundation soil, such as countless anchors complete the re-stabilization effect between the bag body and the main body, the longer the time&# 39; The stronger it is, the more advanced the purpose of building a stable slope is realized, and the maintenance cost is greatly reduced. Eco bag specifications: The material is divided into black geotextile bag, short silk geotextile bag, filament geotextile bag, polypropylene eco-bag Size: 80*40, 81*43 and other specifications Ecological bag Features: 1. Can be constructed on exposed parts left after soilless rocks or landslides. 2. Can be used on non-gravel slopes of expressways and railways. 3. Can be constructed on vertical cliffs. 4. It can be applied in areas where it is impossible to plant and transplant lawns, such as severe saline-alkali areas, soilless roofs, etc. Using the depression of the rock surface of the slope itself, a vegetation bag is used to enclose the weir in the lower part of the depression. The weir is filled with soil and shrubs are mainly planted. The vegetation bag contains cultivated soil, organic matrix, water retention agent and fertilizer prepared in a certain proportion. Or the outside of the slope is directly stacked with an ecological bag trapezoid to form a layer of vegetation bag surface layer. Precautions in eco-bag construction: 1. The vegetation belt on the inner surface of the vegetation bag is fragile. During construction, be sure to take it lightly and lightly to ensure the integrity of the seeds. 2. Be sure to transport the mother soil to the construction site and pack it again. The packed bags should be stacked on the construction surface in time. 3. The bag must contain dry soil, not wet soil with water. 4. If the construction is on a slope with a large slope such as mountain stone or gravel base, be sure to start from the bottom, place a hard PVC pipe every meter away, with a diameter of about 3 to 4 cm, and the length from the base surface to the outside of the vegetation bag wall of the new base. (If it is a gravel base, the other end should be inserted more than 5 cm into the gravel base surface.) Place another layer of PVC pipe when each base reaches a height of 1 meter, or a distance of 1 meter. In this way, the water in the base surface or the surface of the base surface can be discharged, so as not to cause landslides due to soaking the vegetation bag for a long time and causing the soil in the bag to become sludge. 5. In the case of vertical stacking or close to vertical stacking of vegetation bags, a fixed pile should also be placed on the base surface for each stack of 1 meter high. The whole vegetation bag should be tied with a rope and fixed separately on the fixed pile to prevent the wall from collapsing.
