Work method.
Background technology
The settlement issues of soft foundation, directly affects the normal operation of the stable of dyke embankment and road.Treatment technology at present about soft soil base sedimentation mainly contains: replacement cushion method, expansive soil mix grey method, removing silt for replacement method, Lime Flyash Pile Method, loading preloading, overload pre-compaction method, Vacuum-loading Pre-pressing Method, deep mixing method, jet grounting and chemical stabilization etc.Often kind of method has its respective advantage, but also there is respective limitation.Generally speaking, working procedure is many, long in time limit, and is applicable to the place that foundation surface does not have any structure more.
Following methods is had: 1) by arranging weak Squeezing Soil Pile at highway embankment both sides uniform intervals in prior art, slip casting steel pipe is inserted in roadbed bed course, bed course and weak Squeezing Soil Pile form entirety admittedly to form slurry by slip casting, shared top embankment, the method complicated construction technique, need to excavate existing side slope of embankment, destroy the stability of existing embankment, need to carry out supporting time necessary, for the restriction of dyke building due to construction plant condition, the method is also not suitable for, and the method is forming the protuberance easily causing embankment in the solid bed course process of slurry; 2) light soil is utilized to replace the construction method of original embankment filled soil, effectively eliminate the settlement after construction of filler self, decrease the annex stress to ground, finally reach the target reducing Embankment Subsidence, the method work progress is comparatively complicated, and the strength problem do not had from the ground truly solving weak soil, and be not suitable for the soft base engineering of dyke, because under the effect of streamflow, the stability of intensity on dyke of levee foundation has important impact, and the sedimentation and deformation of dyke itself is the standard controlled; 3) for the combination electrode of reinforced soft soil ground, this electrode is welded by four sheet type metal sheets, this electrode is in use also reinforced due to the whole process soil layer that to be metal do not need reinforcement for part, causes waste of material and disposal cost to be increased; 4) in soft rock, arrange that irony electrode carries out the method for soft rock reinforcing, the method adopts single iron staff as electrode, and there is cementing stake diameter less, consolidation effect is not obvious.
In sum, processing method ubiquity complicated construction technique conventional at present, reinforces costly, requires high, really effectively can not solve the strength problem of soft foundation to surrounding enviroment.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of dyke soft base fast processing construction method, the method can be strengthened the dikes when not affecting ground normal traffic soft base, economical rationality simultaneously.
Technical scheme: for achieving the above object, the present invention adopts following technical scheme:
A kind of dyke soft base fast processing construction method, comprises the following steps:
1) according to earthquake prospecting, the position of Soft Soil Layer of determining to need reinforcement bottom dyke and thickness, dyke is arranged on hardpan, and hardpan is on the top of Soft Soil Layer; ;
2) levelling of the land, surveying setting-out, periphery sets up fence and caution board on construction ground;
3) driller insertion, be connected with Y shape battery lead plate with crossover sub through drilling rod by wire, one end of crossover sub is connected with drilling rod, and the other end is connected with Y shape battery lead plate; In dyke both sides by rig respectively to inserting some row's Y shape battery lead plates bottom dyke in the Soft Soil Layer needed reinforcement;
4), after Y shape battery lead plate has inserted, according to the circuit often arranging positive electrode, the requirement at negative electrode interval connects Y shape battery lead plate and wire, connect dc source, the voltage of power supply is 0 ~ 220 volt, and electric current is 0 ~ 300 ampere; When output current is less than 20 ampere-hours, original positive electrode N, negative electrode S are exchanged;
5) repeat step 4) until the intensity of weak soil reaches designing requirement stop energising, extract Y shape battery lead plate.
Described crossover sub is columniform non-metal insulating material.
Described Y shape battery lead plate is welded by three trapezoidal iron plates, and Y shape electrode plate top is welded together by the acute angle of trapezoidal iron plate.
Described Y shape battery lead plate width is 5cm ~ 15cm, and thickness is 0.5 ~ 1.0cm, and length is 100 ~ 300cm.
Distance between adjacent Y shape battery lead plate is 200 ~ 300cm.
Beneficial effect: compared with prior art, the specific area of dyke of the present invention soft base fast processing construction method by adopting Y shape battery lead plate to increase electrode and the soil body, accelerate the electrolysis of electrode, hydrolysis, oxidation and dehydration, expand reinforcing scope, improve consolidation effect; Adopt nonmetal drill stem conversion connector jointed rod and Y shape battery lead plate, avoid drilling rod and electrolysis, hydrolysis, oxidation and dehydration also occur, material unaccounted-for (MUF) can be reduced and reduce the loss of power; By conversion electric power positive and negative electrode, Y shape battery lead plate can be used fully, make can both form gelling reinforcing body at positive and negative electrode two ends; In addition, adopt program construction technology simple, workable, economic benefit is obvious, obvious processing effect.
