Research Of Practical Technology On Geosynthetic Material Used In The Highway Slope Protection In Jilin

The earthwork synthetic material is one kind of new ground engineering material. It is by the synthesized high polymer each kind of type product which makes for raw material. According to Earthwork synthetic material Application Technology standard, earthwork synthetic material is divided into four major kinds: earthwork fabric, earthwork membrane, earthwork synthetic materials and earthwork special material. The research indicated, not only the earthwork synthetic material the performance superior, the application scope is broad, moreover the cost is inexpensive, the economic efficiency is extremely remarkable.This article unifies the Jilin Province physical geography situation and the project characteristic with emphasis, mainly aims at uses in the road side slope protection the earthwork grid (earthwork net, earthwork grille), the earthwork standard room and the earthwork three-dimensional network pad, to the earthwork synthetic material function, the project characteristic and the protection mechanism conducts the analysis research, and the key research earthwork three-dimensional network pad, the earthwork standard room union turfing carries on the side slope protection the practical technology.In the project nature aspect, the earthwork synthetic material has the quality light, anti-corrosive, the flexibility good, the intensity high, is advantageous for the factory manufacture, easy to transport and the storage, easy and the soil body union use, the compatibility strong, the construction cost relative low status merit. May facilitate puts in between the soil body interior, the surface or each soil body, displays its filtration, draining water, the isolation, the reinforcement, guards against infiltrates, functions and so on protection, can make up the natural ground material many physics mechanics aspect the insufficiency.Earthwork synthetic material and turfing union use, not only may display theearthwork synthetic material the performance, enhances the pure turfing side slope protection capability, satisfies the first-class highway side slope the protection request, moreover lays with mortar the slabstone or the concrete pre-clamp dog protection pattern with the tradition compares, but also has the anti-distortion ability strong, the service life long, the beautified environment and reduces merits and so on environmental pollution.In carries on the analysis to the earthwork synthetic material project characteristic in the foundation, the analysis has studied the earthwork grid, the earthwork three-dimensional network pad, the earthwork standard room and the soil body correlation as well as the anti-heave, the freezing and thawing function, provides the rationale and the basis for later engineering test. In order to carries on a more objective appraisal to the existing side slope protection type characteristic and the running condition, then proposed more scientific reasonable, the economy practical, conforms to the ecological environment request synthesis protection technology measure, has carried on the diagnosis to the Jilin Province first-class highway side slope protection project present situation. Through the investigation discovery, Jilin Province's road side slope protection also has some problems, for example: The bricklaying protection and the plant protection union unsatisfactory, the soil texture side slope appears flushes the ditch, sloughs, even phenomena and so on avalanche. According to the above, this article proposed the earthwork composition material synthesis protection pattern, it should solve these question quite ideal method.In order to examine the earthwork synthetic material protection the practical application effect, has carried on the earthwork three-dimensional network pad and the earthwork standard room union turfing protection in the test section (the gate-type arch builds stone, purple sophora tree protection) with other protection form the contrast experiment, has carried on the protection design to each kind of protection form, proposed the construction craft. Observes and the scene sample test result through the later period may see, the earthwork composition materialunion turfing protection can play guards against the washout, guards against the heave and the solid earth slope protection role, simultaneously can beautify the afforested environment, conforms to the ecology environmental protection requirement.In the economic efficiency aspect, the earthwork three-dimensional network pad and the earthwork standard room turfing protection is lower than other protection pattern project construction cost, may save the massive direct engineering cost, has the obvious superiority in the economy. In the technology feasible, the condition is suitable and guarantees the slope protection effect under the premise, should the first choice earthwork synthetic material protection, in particular the earthwork three-dimensional network pad turfing protection.In the social efficiency aspect, the earthwork synthetic material turfing protection may beautify the afforested environment, the reduction environmental pollution, the reduction soil erosion, maintains and restores the ecological equilibrium, these all are other project protection form is unable to compare. The earthwork synthetic material union turfing protection had in the domestic and foreign road side slope protection very applies, through in recent years use observation, thought the earthwork synthetic material union turfing slope protection technology is feasible, the overall effect is good, and the merit is prominent.Looked from the domestic current research and the application present situation that, the earthwork synthetic material union turfing protection technology still was at the initial stage, lacked the comprehensive system the theory and the practical engineering research, very many questions also waited for the time examination and the thorough research. Therefore carries out the earthwork composition material protection practical engineering research, obtains specifically the practical research results promptly, will be able to enhance the side slope protection large scale the effect, the earthwork synthetic material protection application promotion prospect will be able to be extremely broad surely.
