Description
Technical field
The invention belongs to dykes and dams Soft Soils Consolidation in A technical field, it is specifically related to a kind of soft base fast processing of dyke and executes
Work method.
Background technology
The settlement issues of soft clay ground, directly affects the normal operation of the stable of dyke embankment and road. The current process technology about soft soil base sedimentation mainly contains: replacement cushion method, swelling soil mix ash method, removing silt for replacement method, Lime Flyash Pile Method, loading preloading, overload pre-compaction method, combined vacuum and surcharge preloading method, deep mixing method, jet grounting and chemical consolidation method etc. Often kind of method has its advantage separately, 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 structures more.
Prior art has following method: 1) by arranging weak soil compaction stake at even interval, highway embankment both sides, roadbed bed course inserts slip casting steel pipe, bed course and weak soil compaction stake form entirety admittedly to form slurry by slip casting, shared top embankment load, the method construction technology is complicated, need existing embankment side slope to be excavated, destroy the stability of existing embankment, need to carry out supporting time necessary, for the restriction of dyke engineering due to workyard 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 soils is utilized to replace the constructional 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 construction process is comparatively complicated, and not from the strength problem of the ground truly solving weak soil, and it is not suitable for the soft base engineering of dyke, because under the effect of river course current, the stability of dyke is had important impact by the intensity of dike base, the standard that the sedimentation and deformation of dyke itself just controls; 3) for the combined electrode of reinforced soft soil ground, this electrode is welded by four sheet type metal sheets, this electrode does not in use need the soil layer reinforced to reinforce owing to whole process is metal for part yet, causes waste of material and processing costs to be increased; 4) arranging that in soft rock irony electrode carries out the method for soft rock reinforcing, the method adopts single root iron staff as electrode, there is cementing stake diameter less, and consolidation effect is not obvious.
In sum, generally there is construction technology complexity in treatment process conventional at present, reinforces costly, surrounding enviroment is required high, really can not effectively solve the strength problem of soft clay ground.
Summary of the invention
Goal of the invention: it is an object of the invention to provide a kind of soft base fast processing constructional method of dyke, 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 soft base fast processing constructional method of dyke, comprises the following steps:
1) reconnoitring according to earthquake, it is determined that need position and the thickness of reinforcing soft soil layer bottom dyke, dyke is arranged on pan soil layer, and pan soil layer is on the top of weak soil layer; ;
2) levelling of the land, surveying setting-out, sets up fence and warning board at workyard periphery;
3) driller insertion, is connected wire with Y shape battery lead plate through drilling rod and X-over, and one end of X-over 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 weak soil layer needing to reinforce;
4) after Y shape battery lead plate has inserted, according to the circuit often arranging positive electrode, the requirement at negative potential interval connects Y shape battery lead plate and wire, connecting direct supply, the voltage of power supply is 0 ~ 220 volt, and electric current is 0 ~ 300 ampere; When outward current is less than 20 amperes, original positive electrode N, negative potential S are exchanged;
5) repeating step 4) until the intensity of weak soil reaches design requirements stops energising, extract Y shape battery lead plate.
Described X-over is cylindrical non-metal insulating material.
Described Y shape battery lead plate is welded by three trapezoidal iron sheets, and Y shape battery lead plate top is welded together by the acute angle of trapezoidal iron sheet.
Described Y shape battery lead plate width is 5cm ~ 15cm, and thickness is 0.5 ~ 1.0cm, and length is 100 ~ 300cm.
The adjacent distance between Y shape battery lead plate is 200 ~ 300cm.
Useful effect: compared with prior art, by adopting, Y shape battery lead plate increases the specific surface area of electrode and the soil body to the soft base fast processing constructional method of dyke of the present invention, accelerate the electrolysis of electrode, hydrolysis, oxidation and dehydration reaction, expand reinforcing scope, it is to increase consolidation effect; Adopt nonmetal drill stem conversion connector to connect drilling rod and Y shape battery lead plate, avoid drilling rod and electrolysis, hydrolysis, oxidation and dehydration reaction also occur, it is possible to reduce material unaccounted-for (MUF) and reduce power supply loss; By conversion electric power positive and negative electrode, it is possible to use Y shape battery lead plate fully so that gelling can both be formed at positive and negative electrode two ends and add solid; In addition, adopting program construction technology simple, workable, economic benefit is obvious, obvious processing effect.
