Description
Technical field
It the utility model is related to field of road construction, and in particular to one kind fastens anti-scattered water-impervious dirt road based structures.
Background technology
With developing rapidly for China's Transport Facility Construction, highway, railway infrastructure project are growing day by day, many highways
Need to pass through Special soil area, associated is then the Special soil local highway roadbed construction method and calamity to become increasingly conspicuous therewith
Evil problem.
Special soil refers to the soil with special composition, state, architectural feature and engineering properties, common are dilatancy
Soil, collapsible loess, admaic earth, salinized soil etc..As swelling weak rock has a dehydration shrinkage cracking, the characteristic of water swelling softening,
The intensity of swelling weak rock can be greatly lowered after water suction, under embankment deadweight and action of traffic loading basis can be made to sink or even lose
It is steady to destroy；And for example collapsible loess, when not by water-soaked, its intensity is higher, and compressibility is smaller, but under a certain pressure by water
Soak, soil structure can be destroyed rapidly, and intensity reduces rapidly, so as to produce larger additional deformation.So Special soil road structure
Unstable failure has very big associate with " hydric factor ".
For the road structure built in Special soil area, its processing method can be summarized as three classes at present, one is adopting
With cushion, so-called cushion refers to excavate a range of Special soil below foundation ground, then backfill intensity it is high,
Compressibility is low and without rodent filler；The second is using the Scheme of Strengthening of improvement Special soil, improvement Special soil point
For physically improved and chemical modifying, physically improved is the particle size for being changed by mixing rubble etc. soil, and chemical modifying is to pass through
Incorporation cement, lime etc. solidify agent material to improve its engineering property；The third is sand bedding course is added to be reinforced with composite geo-membrane
Processing, the purpose of water proof is reached using composite geo-membrane parcel Special soil.
Above-mentioned three kinds of processing methods are respectively present following deficiency, and first method needs a large amount of well-behaved soil bodys
Special soil is replaced, so considerably increases the freight volume of the earthwork, necessarily causes investment to increase, construction safety environmental degradation；The
Two kinds of method construction periods are long, technique is also complex；The third method is due to composite geo-membrane short of width, it is difficult to envelope completely
Bedding is closed, and composite geo-membrane is subject to the destruction of construction machinery in work progress, so as to reduce waterproof effect.
For the reinforcement and bank protection of roadbed, frequently with geosynthetics, geotechnique's synthesis material in traditional processing method
Material can improve the stability of road structure, but its raw material is high molecular polymer, and production needs to consume mass energy, while
Substantial amounts of pollutant can be produced, can so cause the consuming of the energy and the pollution of environment, therefore, advocating sustainable development energetically
Today of exhibition, we need to find the material of low-carbon environment-friendly to substitute.
