Boyuan geotextile material is a professional engaged in geocell, three-dimensional vegetation net, geotechnical grille and other plastic products research, development and production of integrated enterprise, is China geosynthetics Engineering Association member units, is a high starting point, the rapid development of modern geotechnical synthetic materials production enterprises.
Boyuan geotechnical engineering mechanical properties of the improved better engineering materials, in some foreign engineering has been applied early, mainly used in engineering soft foundation treatment, railway and highway subgrade reinforcement, river slope greening, bridge joint jump bridge, dam slope greening and reinforcement corrosion, according to foreign experience in engineering, and pre engineering experience accumulation, now geocell applied in railway and highway slope greening engineering construction scheme for a description.
As to further improve the people's understanding of the natural environment, the importance and beauty of slope revegetation engineering also had the further understanding of the engineering and the natural environment more integrated and slope protection also changed the previous stereotyped form, using a variety of engineering materials. Geocell is the one with convenient construction, high survival rate of planting grass, good protective properties of slope, the relatively high efficiency of a material.
Grid materials for different slope, you can choose different types of grid applications. The slopes are generally less than 1 / 2 (45 degrees) can be application 5cm x 25 x 25 cell room, if the slope greater than 45 degrees should choose 10cm x 25 x 25 compartments, slope slope reached 55 degrees, or 45 degree slope height is greater than 10m, should use 150cm x 25 x 25 compartments, the upper slope shall try to use a 10cm compartment, side slope greening should be mainly with turf or suitable for local climate grasses and can also grow a certain number of low tree species, an increase of pavement layer and the slope stability coupling.
Paving should pay attention to the following aspects of the room:
Boyuan geocell construction preparation:
1, the working surface: has been part of the slope has to meet the requirements, repair slope construction is in progress, work will continue to provide, planar slope relation degree to the success or failure of the geocell planting protection. The slope of the slope is not usually laid, the geotechnical grid is easy to produce stress concentration, so that the grid room solder joint cracking, resulting in the case of cross foot and so on. Therefore, must be flat slope to the design requirements, and the use of artificial slope repair, removal of dangerous rock slope pumice, etc.
2, pavement compartment of the slope should be set main drainage ditch system, distance between two adjacent ditch keep 4m, drainage ditch with the side of the road ditch is communicated, the road area of water along the side ditch drainage channel flow into the edge of the road, lest Road area of water to prevent scour compartment slope protection.
3, the top level of the slope surface treatment, removal of the grid is not conducive to the laying of a number of debris, so that the slope to maintain a smooth, strong, can also sprinkle a layer of quality soil, in order to facilitate the growth of plant.
4, the room should be in the direction of the main force, by the laying down, so that the grid of the sheet is perpendicular to the highway subgrade. Must not be laid horizontally.
5, fully open grid component, and at the top of each frame nail into a hook shaped rivet riveting pile, pile length requirements for lattice chamber height of 2 more 30cm, such as 5cm chamber, it should be the riveting pile of 2 * 5cm+30cm, 40cm length, 10cm compartment pile which should be riveting 2 x 10+30 50cm long, along two sides of the nail into the drainage side riveting pile, pile of bamboo shaped, mainly to open chamber, the middle and the bottom is also used bamboo pile like Zhang Lagrange room, at the top of pile play a major role. The suspension and riveted compartment, should be used good materials, such as steel, surrounded by 16 Oslash; "U" type of reinforced slope and fixed spacing 70CM, middle Oslash; 12 "F" type of reinforced slope anchor fixed triangular fixed distance is 1.05M, each node is tightly fixed on the slope. The drill rod must be perpendicular to the slope, the other is mainly played during the construction of Zhang Gulag room and available materials is relatively simple.
6, and geocell Zhang opened and riveting tight, suitable for planting grass or grass seed quality soil down filled compartment space, filled with should to compartment 1.2 times the height is preferred and beat the strong, timely and vegetation.
7, for the road below slope, drainage ditch shall be and retaining ditch creation connecting to and drainage of surface water and scouring slope protection for highway slope should be in the upper slope top line set up resistance ditch, the upper slope height of water resistance ditch flows into the drainage ditch, avoiding accumulation of water erosion of slope protection, the upper slope should as far as possible the use of geotextile chamber height is higher.
8, after the completion of the construction, we should do a good job of re examination, the tension filled into rivet top pile is not solid should be timely rework, until the turf or grass survived completely.
Note:
1, the bolt hole position, must be located in the top of the grid, to ensure that the weight of the grid can spread to the anchor.
2, Between geocell and geocell must be fully connected to form a film, as a whole.
3, in order to prevent water erosion of geocell, Ponding construction waterproofing ridge to prevent rainwater from the top of the hill is poured into the damaged compartment and the drainage is not smooth at, timely and clear.
