Description
One, technical field
The present invention relates to a kind of method for processing foundation, especially chopped fiber reinforced rendzinas ground treatment method.
Two, background technology
Method for processing foundation can be divided into two classes substantially at present, i.e. antihunt means and reinforcement method.Common antihunt means mainly contain lime improvement, cement improvement, two ash improvement and polymer reactant improvement etc.General reinforcement method comprises geotextiles, geomembrane, geo-grid, continuous fiber reinforced earth method etc.
As a kind of cheapness and stabilizing agent efficiently, lime has been brought into play very big effect in the soil nature improvement.Lime mix crushing resistance, shear resistance, water stability and the frost resistance that can improve engineering soil significantly, reduce its swell-shrink characteristic, index of plasticity and maximum dry density.Although lime has been improved a lot of engineering propertiess of soil effectively, it has also brought some negative effects simultaneously: (1) lime improving effect has reduced native plasticity and has increased the pH value of soil, and this can cause soil sandization and environment pollution; (2) banketing after the lime improvement can show very strong fragility, and the unexpected unstability that this can cause the soil body has seriously influenced the safety and the stability of engineering.
In recent years, along with the fast development of chemical synthesis industry, artificial synthetic fibers have become a kind of novel reinforcement material, are applied to concrete work and geotechnical engineering field widely.At present, the use of fiber and steel bar reinforced method in concrete work is comparatively ripe, and it can improve the toughness, intensity, cracking resistance, tension of concrete/cement mortar and the performance of aspect such as impervious.In the geotechnical engineering field, fiber and steel bar reinforced indigenous method begins to be subjected to people's attention and attention.Fiber and steel bar reinforced soil (abbreviating fiber soil as) is to banket by a certain proportion of fibre is incorporated into, and the engineering properties of soil is improved.It is sensu lato reinforced earth, and its working mechanism is similar to reinforced earth, promptly utilizes frictional force or snap-in force between fiber and the soil particle to improve the ability that the soil body is resisted the external force effect.Compare general reinforced earth and Stabilized Soil, fiber soil has following advantage: the distribution of (1) fiber in soil is uniform, thereby fiber soil has approximate isotropic mechanical property, not only can limit the lateral deformation of soil, can also control vertical deformation, this be stratification be distributed in rib in the soil and geotextile can't realize; (2) fiber soil has high toughness, presents the plastic failure feature of strain hardening during destruction, and this helps the safety and the stability of engineering; (3) fiber soil has higher crack resistance, can be suitable for solving the sedimentation and the dry-shrinkage deformed problems of crack that often occur in the geotechnical engineering; (4) fiber soil has the effect of energy-eliminating shock-absorbing preferably, has improved the anti-fatigue performance of roadbed and ground under the dynamic load effect widely, has prolonged its application life; (5) fibers content very low (weight ratio is less than 0.2%) in the general fiber soil, thereby fiber soil relatively approaches the soil of native state, at compounds such as its jet surface grass-seed and nutritional agents, can reach the effect of greening environment.Although the advantage of fiber soil is a lot, it still exists some shortcomings: the strengthening action of (1) fiber is not very outstanding, and the intensity increase rate of soil is little behind the reinforcement, far away from the intensity of lime or cement stabilized soil; (2) water stability of fiber soil is relatively poor, and immersion a period of time, disintegration can take place.
Three, summary of the invention
The objective of the invention is: it is staple fiber reinforcement rendzinas method that a kind of new method for processing foundation is provided.This method organically combines lime stabilization method and fiber and steel bar reinforced indigenous method, not only can bring into play both advantages, can also remedy the deficiency that exists separately, and the engineering propertiess such as intensity, toughness, swell-shrink characteristic and water stability of soil are all improved.
Chopped fiber reinforced rendzinas ground treatment method, the method that adopts staple fiber reinforcement and lime stabilization to combine, staple fiber and lime are mixed in the engineering soil to improve the engineering properties of soil, being used for ground handles, wherein fibers content is heavy for the 0.05-0.5% dry ground, and the volume 1-10% dry ground of lime is heavy; The fibre of fibre length 2mm to 30mm, ground is filled out, is rolled into to this soil through mix, heap.
The mix method of binder in the inventive method (fiber, lime and soil) is it can be divided into two classes by scope of construction item: mixer mix and job mix.Small-scale engineering construction (as side slope, retaining wall) can be adopted the mixer mix, can transport directly to purpose place heap as the soil after adopting rotary mixer with the even mix of fiber, lime and soil and fill out; Roll.And large-scale roadbed or foundation treatment engineering should adopt job mix, directly carry out fiber and lime, native mix at the construction field (site) and roll: be followed successively by and dig loose earth filling on the ground, the lime that paves, lime turn, jet fiber, fiber mix and stir, surface evening and cal rolling.
The mixer mix stirs lime and soil earlier, adopting small-sized hair-dryer that fibre is blown in the mixer and with lime, soil equably then stirs, mixing time is controlled at 5～10min, if still have bunched fiber, then can prolong and stir 1～2min.Adopt earlier spike-tooth harrow with lime with banket and carry out 2～4 times turn and soil block is smashed processing, the particle diameter that bankets after smashing is controlled at below the 5cm; Adopt air compressor that fibre is ejected into the rendzinas surface then; Adopt spike-tooth harrow fibre and rendzinas to be carried out 2～4 times scarifying again.
Fiber adopts macromolecular fibre: select in following several fibers: polypropylene fibre, polyester fiber, Fypro, polyethylene, polyvinyl chloride or polyacrylonitrile fibre, also can use any two or more fiber with; Fibre length is 5mm to 20mm especially.Fibers content 0.05-0.2% dry ground is heavy.
Fiber and lime, soil mix the time water content be the 4-15% weight ratio.
Construction technology roughly is divided into 7 steps, is followed successively by and digs that loose earth filling, the lime that paves, lime turn, jet fiber, fiber mix and stir, surface evening and cal rolling.
The fiber of selecting for use has enough resistance to acids and basess and safety, higher deformability, tensile strength, adhesion strength, modulus of elasticity and cost performance, good dispersiveness, production scale is big and product batches stable, therefore selectable kinds of fibers is a macromolecular fibre, comprises polypropylene fibre, polyester fiber, Fypro, polyethylene, polyvinyl chloride, polyacrylonitrile fibre.
In the construction method one: earlier lime and soil are stirred, adopting small-sized hair-dryer that fibre is blown in the mixer and with lime, soil equably then stirs, mixing time is controlled at 5～6min, if still have bunched fiber, then can prolong and stir 1～2min.
In the construction method two: or adopt earlier spike-tooth harrow with lime with banket and carry out 2～4 times turn and soil block is smashed processing, the particle diameter that bankets after smashing is controlled at below the 5cm; Adopt air compressor that fibre is ejected into the rendzinas surface then; Adopt spike-tooth harrow fibre and rendzinas to be carried out 2～4 times scarifying again.
Embodiments of the present invention are: earlier lime is fully mixed the formation rendzinas with engineering soil, and then staple fiber is incorporated in the rendzinas equably to form staple fiber reinforcement rendzinas (being called for short cebollite dirt).Because lime is relevant with reaction and time between the soil, so engineering propertiess such as the intensity of cebollite dirt, swell-shrink characteristic and water stability are subjected to the influence in the length of time, its curing time and condition are similar to rendzinas.
Exist two kinds of mechanisms of action in the cebollite dirt: first kind is the chemical action between dirt, this effect makes soil particle generation flocculation, thereby caused soil structure comparatively fine and close, this makes moisture be difficult to enter in the soil and reacts with particle, show as high water stability and low swell-shrink characteristic on engineering properties, in addition, the chemical reaction between dirt has also generated calcareous cement, increase connection power and snap-in force between soil particle, made the intensity of soil increase substantially; Second kind is the physical action between fiber and the soil, and native suffered pulling force has been born in the rubbing action between fibre and soil particle, thereby has stoped the growth in crack in the soil effectively, has improved the toughness of rendzinas, has changed the brittle fracture feature of rendzinas.
The characteristics of this method mainly show as: (1) rendzinas behind the staple fiber reinforcement has higher intensity, toughness and cracking resistance, and its destructive characteristics is higher from plastic failure and residual strength that brittle fracture completely changes strain softening into; (2) rendzinas behind the reinforcement still has high water stability and low swell-shrink characteristic; (3) under the situation of guaranteed strength, mixing of fiber can suitably reduce the consumption of lime, thereby reduced the degree of soil sandization and environment pollution; (4) the method cost is not high, and the construction technology simple possible is applicable to ground and hydraulic engineering fields such as side slope, retaining wall, roadbed, ground and embankments.
