Abstract
A device for treating soft soil foundation/tail slag/lake sludge via pressurization, vacuum preloading and consolidation belongs to soft soil foundation/tail slag/lake sludge construction device, which comprises plastic drainage plates, wherein the top ends of the plastic drainage plates horizontally distributed in a plurality of rows in soil/mine slag/sludge are directly accessed into vacuum tubes; the soil/mine slag/sludge among the plastic drainage plates is uniformly distributed with water permeable ascending pipes. The device can implement the reinforcement mechanism and effect of vacuum preloading on viscous soil/mine slag/sludge, to improve consolidation depth of one power, reduce reinforcement time of one power and reduce production cost.
Description
Technical field
The utility model belongs to soft foundation/mine tailings/lake silt construction equipment, refers in particular to a kind of soft soil foundation/mine tailings that utilize supercharging, vacuum preloading mode to improve the soil body/slag/silt consolidation degree fast/lake silt device.
Background technology
At present, the soft base processing method of China has: 1, and the vacuum preconsolidation method; 2, dynamic compaction; 3, preloading; 4, vacuum pre-pressed joint preloading.Above several method is effective substantially to sandy soil layer, general soil layer, but it is all invalid to cohesive soil vacuum preconsolidation method, dynamic compaction, can only take preloading and vacuum pre-pressed joint preloading, but these two kinds of costs are higher, must lay the 50cm sand bedding course on the viscous layer, and not environmental protection, it is very big that the preloading filler is obtained difficulty, and engineering time is very long.For special viscosity soil property (transmission coefficient 〉=10
-7Silt matter clay), all can't solve the problem of consolidation strength and engineering time with the equipment of above several method, can't be applicable to the special building needs that highway in China, railway, harbour and antidetonation rank are high.
The slag of China's tailing dam is built height after handling general employing box dam, and make its precipitation, and then build height, reppd method, its poor stability, when the slag water content was big, the dam body lateral pressure increased, and can occur striding stepping on, and potential safety hazard is big.
The lake silt of China adopts the accumulation mode air dry, disposes a pond often and then pollutes plot, and is big to environmental nuisance.
Summary of the invention
The utility model in order to overcome above-mentioned deficiency, provides the device of a kind of soft soil foundation/mine tailings/lake silt just, i.e. supercharging vacuum preconsolidation soft soil foundation/mine tailings/lake silt device.Main innovation is the soil body/slag/mud is imposed vacuum and supercharging simultaneously, and vacuum allows the soil body/slag/mud moisture discharge fast, and the supercharging guiding soil body/slag/mud hydrone directed flow improves consolidation rate.Specifically implement like this: supercharging vacuum preconsolidation soft soil foundation/mine tailings/lake silt device, vacuum tube is directly inserted on the top that it is characterized in that the plurality of rows plastic draining board that level is arranged in the soil body/slag/mud, and permeable pressure inlet evenly distributes in the soil body/slag between plastic draining board/mud.
By vacuum tube the plastic draining intralamellar part is vacuumized, can make the vacuum tube system keep unimpeded, the grains of sand can't enter the vacuum tube system, the vacuum plastic draining intralamellar part that goes directly, the plastic draining board filter membrane is inside and outside to produce big pressure reduction, and water content is discharged fast.Adopt the hand y junction y when plastic draining board is connected with vacuum tube, described hand y junction y is made up of two parts, and the lower end is hollow box, and the protruding pipe that several are evenly distributed is set on the upper surface length direction of hollow box.(seeing the applicant's utility model patent ZL200620068366.3 for details).
Permeable pressure inlet evenly distributes in the soil body/slag between plastic draining board/mud, can be to the even supercharging of the part soil body/slag/mud between plastic draining board, make the soil body/slag/mud hydrone directed flow under pressure, carry out rapidly solidified to soft base/mine tailings/lake silt, in the limited duration, increase substantially ground/slag/mud intensity and consolidated depth, eliminate settlement after construction, actual effect is better.Permeable preferably pressure inlet is the permeable pressure inlet of horizontal well (REFERENCE TO RELATED people's practical new patent ZL03220509.0) in the utility model, form by the Water penetrative flexible pipe that some joints link to each other successively, Water penetrative flexible pipe is made up of spirality flexible supporting frames and filter cloth, two of every joint Water penetrative flexible pipe is equipped with the nipple that can connect, be connected with conical head on the first segment flexible pipe front end, minor details flexible pipe rear end is connected with flange.This can the filtration and the permeable pressure inlet of shrinkable horizontal well distribution pressure at the uniform velocity, make the soil body/slag/mud hydrone under pressure directed flow improve consolidation rate.
Each plastic removal material band drain of horizontal positioned is the regular hexagon layout in the utility model, and a permeable pressure inlet is placed at each orthohexagonal center.Distance between each plastic draining board can be designed to 0.8-1.5m, only need during construction the plastic draining board along continuous straight runs is put in argillic horizon/slag/mud, this layout type can be saved sand bedding course and reduce construction costs when construction, can bring into play maximum draining and diversion function, guarantees treatment effect.
Device described in the utility model can make the reinforcement mechanism of vacuum preloading and consolidation effect obtain true embodiment on viscosity soil property/slag/mud, and consolidated depth is doubled, Gu the strong time has shortened half, cost is lower.
