The unique place of the Gebin Stone Cage Network is similar to that of traditional masonry and plain cement. The Gebin Stone Cage has the following unique features:
1) It is suitable for variants with strong experience. As a flexible structure, Gebin Stone Cage can bear a wide range of variations and cause cracks. The material in the stone cage is restrained by the stone cage after the shock, and will not run outside the stone cage, but will be debugged to reach a new equilibrium.
2) Good group. The honeycomb grid of the Gebin gabion is a double-hinged structure, and the department is very urgent. The same cage is considered suitable and the steel wire is twisted and integrated. The stone cage is deformed under the external force effect, but it is not stone. The integrity of the cage group structure, even if there is a wire in the structure, will not affect its structure. This unique place of the gabstone cage is superior to the rigid and semi-rigid structure.
3) The grid makes the whole stone cages strong. Even if the individual wires are broken, the mesh will not be casual. At the same time, the stone cages are considered suitable and used, and they are urgently connected.
4) Good durability. The steel wire of Gebin Stone Cage is hot-dip galvanized and coated with anti-corrosion treatment. It has the durability and the life span of one hundred years.
5) The anti-scour has strong experience. After the gabstone cage is filled with the block stone, the maximum impact flow rate can reach 5~/s.
6) Water permeable and self-draining. Because the stone in the Gebin stone cage has a hole in the eye, the pore water in the soil behind the stone cage is easy to discharge, thus reducing the Spring pressure behind the stone cage. In addition to the passage of time, these caves will be filled with raw soil, so conditions for the beautification and vegetation are invented, and even if they are not broadcast, the plants will naturally grow. This unique place makes the Gebin gabion have high ecological value in the revetment and slope protection of the river gate.
In combination with the above unique places, Gebin Stone Cage Protection is a new way of rivers and dangers protection. It shows the pre-set concept of coexistence between man and nature, and is more suitable for the treatment of landscape rivers. Gebin stone cage has high degree of flexibility, can change gender, has good flexibility, has strong anti-variation ability, has satisfactory permeability, increases the utility of slope protection group and stability, and does not affect the normal performance of slope protection performance. The restrictions on the start-up season, especially in the cold winter, can also be started in groups. The construction is convenient, agile, and the timeline is short, saving money.
3. The engineering preset parameters confirm that it is suitable to use the Gebin net slope protection section, the Gebin stone cage top elevation is 5.00m, and the Gebin stone cage foundation top elevation is 2.50m. The Gebin stone cage slope is 250mm thick, the preset slope ratio is 1:2.0, the lower gravel cushion is 100mm thick, and the lower pavement is 200g/m2 geotextile. The slope protection foundation is considered suitable and the Gebin stone cage is used. The foundation depth is 1.5. m, width 1.0m. Class A stone is filled in the Gebin stone cage.
4. Start-up process 4.1 The basic construction of the river channel makes the water flow as appropriate and uses the 1m3 excavator to excavate the earth. The bulldozer is suitable for construction, and the earthwork is directly backfilled. The litchi earthwork is transported to the Jiaozhou industrial base with 8t self-unloading vehicles. The earthwork backfill is considered suitable and the bulldozer is leveled and the 74KW chain rail tractor compacts the soil. The thickness of each layer of paving shall not exceed 30 cm, and each layer shall be not less than 6 times. During the rolling process, the deviation between the guaranteed moisture content and the optimum moisture content is more than 3 percent. Because the river is long and the geological conditions are more complicated, there are silt, silty clay, medium coarse sand, coarse gravel sand in the river channel, etc. When the embankment is filled, the crushing attempt is applied to each soil that meets the requirements of the embankment. In order to confirm the optimal rolling parameters of various soils. When the water content of the backfill is too high, measures such as loosening, drying, and mixing with dry soil are adopted; when the water content is too low, the pre-spraying moisture moisturizing or increasing the number of rolling passes is adopted.
4.2 Slope surface construction Before the engineering protection, according to the specific conditions of the river channel curve, the flow direction is segmented. Each slope slope is self-contained as the simplest surface with a slope ratio of 1:2.0. Unfairness is unfair or sloped or backfilled, and the animal caves and plant roots on the slope are removed. On the flat and sloping slope surface, first lay a layer of 200g/m2 non-woven geotextile, then lay a 100mm thick gravel cushion on it, and install the first layer of the grate cage on the slope from the foundation. It is supplemented with Class A stone, and then covered with the same quality Gebin net, and the box cage and the cage cage are overlapped with the Gebin net cover by the jointing wire; then the slope is paved along the first floor. Repair the second layer of the Gebin box cage to add the shards, install the staggered seams between the layers, and use the cover to cross each other, and so on, and use the gabbin cage to fill the slabs and make them a complete slope. surface.
5. Quality control The main channel of the river channel is guaranteed to be strictly placed according to the preset line, and the foundation depth is guaranteed to meet the preset requirements. Before the bank slope is protected, the slope surface is firstly refurbished, the slope surface is corrected smoothly, and the dike body packing is compacted. The stones used in the gabstone stone cage slope protection should be selected from the novel, strong and hard granules, and the uniform thickness is not less than 20cm. The small joints between the stones are filled with small stones to fill the emergency, and the construction is strictly required according to the requirements of the construction specifications. The stone material after entering the site is considered to be suitable and is manually transported and then transported to the office surface with a rubber wheeler and transported in place. The masonry craftsmanship is considered to be suitable and artificially started. The Shimin soil mortar is suitable for mixing with a mortar mixer and transported to the office surface by a rubber wheel. The stone mason craftsman started the work and adhered to the "Code for Acceptance of Masonry Engineering Quality" (GB50203-2002).
