Description
Technical field
The present invention relates to a kind of pile composite foundation construction method using burning city domestic garbage bottom ash as main aggregate,
Belong to solid waste resource recovery to utilize and foundation treatment technology field.
Background technology
For remaining bottom ash as solid waste, method of disposal main at present is to send to fill out after municipal solid wastes incineration power generation
Field landfill is buried, it is necessary to take a large amount of landfill places.And burning city domestic garbage bottom ash is to its minimizing as construction material
With the effective way of recycling disposal, mix with other construction materials or filled after cementing available for road, ground is changed and filled out
Material.The fender post in composite foundation with piles in inhomogeneous strata and deep footing groove enclosing structure in Soft foundation treatment technology is directed to glutinous
The application of knot body stake, commonly use the pile body of cohesiveness stake typically using cement as the granular media such as cementing agent, cementing rubble, sand aggregate or
The natural rock-filleds such as clay, silt, form cohesiveness stake.Meanwhile also there are some to be sticked using other chemical, biological cementing material constructions
The technology of knot body stake is applied.Microorganism induction calcium carbonate crystal technology (MICP technologies) can also realize the glue of discrete material
Knot, but for different cementing object, its gluing method and difference on effect are notable, currently used for cementing topsoil, silt and
Stickiness soil particle, enable the originally loose soil body that there is higher intensity, and have the advantages of ecological, environmentally friendly.By urban life
Waste incineration bottom ash becomes cohesiveness stake as aggregate using microorganism consolidation techniques, it is possible to achieve with the construction of environmental protection
Technology solves solid waste resource recovery using the organic unity with foundation treatment.
The technical scheme of prior art one
Cement earth pile, soil is stirred into pile on the spot according to a certain ratio with cement with Mixing Machine, technique includes powder jetting
The methods of mixing pile, wet spraying pile, bidirectional stirring pile, by stirring drill bit cementing material such as gunite or cement flour into soil
Afterwards, make cementing material and soil body mix with the rotation pressure of stirring-head blade, cement soil pile is made.
The shortcomings that prior art one
Cement is as cement soil pile major gelled material, and usage amount is larger, and cement is the material of highly energy-consuming, high pollution,
Caused nitrogen oxides in prepared by dust emission, clinker, all produces very big harm to environment.
The technical scheme of prior art two
CFG stakes, mixed and stirred in advance as pile shaft material by rubble, aggregate chips, sand, flyash mixed cement plus water, using immersed tube side
On ground, into pile shaft material after stake holes, is irrigated, CFG stakes are made after maintenance hardening in method.
The shortcomings that prior art three
Although CFG stakes make use of industrial waste flyash as one of aggregate, but still use the water of highly energy-consuming high pollution
Mud material, and pile body uses crushed stone material, it is big to the consumption of natural rubble resource.
The technical scheme of prior art three
Industrial waste mixing pile, by the use of solid industrial waste material as deep-mixed pile cementing agent, with Mixing Machine by soil with
Cement stirs pile on the spot according to a certain ratio, and including slag, high calcium ash, combination ash etc. using industrial waste is used as main agglutination material
Material, fluorgypsum etc. are used as exciting agent, and substitution portland cement makes cementing stake.
The shortcomings that prior art three
The content of beary metal that industrial waste is stirred in native leachate is high, there is certain pollution to groundwater environment.
The technical scheme of prior art four
Microorganism slip casting sand drain, stake holes is made on pending soft base, pours into sand and form sand pile, inject microbial bacteria
Liquid and nutrient salt solution, make sand grains cementing by microorganism induction calcium carbonate crystal technology, microorganism slip casting sand drain is made.
The shortcomings that prior art four
Pile body aggregate is using sand as raw material, the function without consumption solid waste, it is impossible to realize solid waste
Thing recycling；Only injected during pile driving construction, do not reclaim slurries, there may be bad shadow to pile peripheral earth for cementing raffinate
Ring.
The content of the invention
Technical problem：Mostly using cement material, crushed stone material, Environmental costs are high, utilize chemical drugs for existing cementing stake
Agent solidification can pollute to the body of groundwater soil body, and the purpose of the present invention is the bone by the use of waste incineration bottom ash as cohesiveness stake
Material, using microorganism induction calcium carbonate crystal technology, after stake holes is made, using the cinder from refuse incineration perfusion of mix bacterium solution, glue
Liquid grout is tied, fixed, urase hydrolysis is adsorbed by microbial cells, crystallizes the process such as cementing, cinder from refuse incineration stake is made.Should
Cinder from refuse incineration twice laid is saved the material such as cement material and natural rubble, sand by construction method, there is good economic effect
Benefit, the cementing means of microorganism have the good feature of environmental protection, there is good environmental benefit.
