Description
Technical field
The invention belongs to Soft Soil Subgrade Treatment Techniques fields, and in particular to a kind of environmental protection mud makes the construction method on island.
Background technique
With the people's livelihood such as industry park, harbour, airport, power station building the development demand in seashore soil, especially population
Development, many countries need to want soil, that is, to reclaim fields from the sea to ocean.And enclose extra large reclamation by pumping filling can be the advantage of lower cost the case where
Under, problems of land utilization is solved, plays relaxation effect for alleviating economic development and the insufficient contradiction of construction land.Extra large hydraulic reclamation is enclosed to make
The major project content on ground is divided into two steps: first is that first enclosing sea builds embankment, second is that into embankment, hydraulic reclamation backfills to form land-based area again.
Dredger Filling Engineering refer to the silt particle that sea area beach deposits is formed by waterpower hydraulic reclamation to presumptive area with dredger it is heavy
Product soil.These barged-in fills have the characteristics that water content is high, void ratio is big, compressibility is high, shearing strength is low, infiltration coefficient is small, one
As in it is soft modeling arrive liquid-plastic state.In order to improve the engineering properties of barged-in fill, the bearing capacity of blowing filling soft soil foundation is improved, it is also necessary into
The processing of row blowing filling soft soil foundation generallys use physical method and applies a constant load, soil body pore water is discharged, and pore volume becomes
It is small, the soil body is closely knit, make barged-in fill fastly rapid-result land, have use condition.
The main method for the treatment of of soft foundation includes following several:
(1) preloading: preloading is to be classified preloading in the soft base for being provided with horizontal and vertical drainage channel
Sand material, it is closely knit using being drained under heap material containing load action, a kind of physics reinforcement means of ground preloading is carried out to soft soil foundation.
Base pressure needed for load usually takes construction land is as prefabricating load.
(2) vacuum method: vacuum method is sealed in the soft base for being provided with horizontal and vertical drainage channel
It is vacuumized under film, pumps water and air and generate vacuum, using atmospheric pressure as precompressed.It passes through the pore water pressure for reducing ground
Power improves ground effective stress, to accelerate ground consolidation.
(3) vacuum combined stack-load method: vacuum preloading combined with stacking method is to be provided with the soft of horizontal and vertical drainage channel
It is sealed under film and vacuumizes on base, then carry out preloading, and continue to vacuumize, using atmospheric pressure and heap material containing load as precompressed
Load.
Above-mentioned several method is directed to by the water discharge in soft soil foundation, usually by the sewage direct emission of discharge, seriously
Affect the environment of surrounding.
Summary of the invention
Purpose of the invention is to overcome the shortcomings in the prior art, provides the construction party that a kind of environmentally friendly mud makes island
Method.
In order to achieve the above object, the invention is realized by the following technical scheme:
A kind of environmental protection mud makes the construction method on island, includes the following steps:
Step (1) backfills mud making in the region of island；
Step (2), is inserted into drain bar in the mud of backfill；
Step (3), in the waterproof film in one layer of the mud upper berth of backfill；
Step (4), in the upper surface of described waterproof film along embankment is arranged around it；
Drain bar in insertion backfill mud is carried out vacuum drainage by step (5), and the sewage of discharge injects in embankment, with
Load precompressed is carried out to the mud of backfill；
Step (6), is handled sewage in embankment, is then exhausted from after reaching discharge standard.
Preferred embodiment in accordance with the present invention is separated at least three regions, respectively cesspool, processing in the embankment
Pond and clear water reserviors, the sewage injected in embankment are introduced into cesspool, and processing pond is entered after preliminary sedimentation, after processing is up to standard
Water enters clear water reserviors, discharge of finally selecting a good opportunity.
Preferred embodiment in accordance with the present invention increases the step of being laid with geotextiles and placing bamboo raft before step (3),
To promote the bearing capacity of backfill mud.
Preferred embodiment in accordance with the present invention, the bamboo raft are the bamboo raft being bundled into using bamboo by groined type.
Preferred embodiment in accordance with the present invention, sewage water treatment method described in step (6) includes neutralisation, chemical precipitation
Method, oxidation-reduction method, chemical disinfection.
Compared with prior art, the construction method that environmentally friendly mud of the invention makes island has the following beneficial effects: the present invention
Environmentally friendly mud make the construction method on island, the sewage that vacuum in mud is discharged carries out sewage treatment in embankment, reaches sewage
It is then exhausted from after to discharge standard, the influence to ambient enviroment is preferably minimized, is more advantageous to environmental protection.
Specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described.It should be understood that following embodiment is merely to illustrate this
The range of invention and is not intended to limit the present invention.
Sewage water treatment method used in following embodiment includes neutralisation, chemical precipitation method, oxidation-reduction method, chemistry
Sterilization.Wherein, neutralisation, being applicable in sour water, perhaps alkaline sewage can be used that dispensing neutralizes or filtering neutralizes, when processing
Need mixing pit；Chemical precipitation method is to put into chemical agent to sewage, is allowed to directly send out with the pollutant of the solubilised state in sewage
Biochemical reaction forms the solid product of indissoluble, is then separated by solid-liquid separation, so that pollutant is removed, suitable for sewage
