Description
Technical field
The present invention relates to reinforcement of soft soil technical field, in particular to a kind of drain bar for reinforcing soft ground, reinforcing
System and reinforcement means.
Background technique
With the economic sustained and rapid development in China, population is constantly dense, and land demand is growing.It is nervous to alleviate land used
Problem, reclaiming land around sea are increasingly being applied in engineering practice (the large area such as Dong Zhiliang, Liu Jia reclamation engineering key
Technical research and utilization [J] marine traffic engineering, 2015, (2): 9-17.).At present frequently with direct hydraulic reclamation in reclamation engineering
Method, and consolidation process is carried out to large area deep soft soil foundation, it is to ensure that the key of reclaiming land around sea.Reinforcing soft ground in engineering
Conventional treatment method generally have vacuum method, electro-osmosis method and vacuum preloading combined with electroosmosis etc..
The technical solution of the prior art one
Firstly, setting vertical drain (bag after being laid with horizontal drainage bed course (such as sand bedding course) on the ground to need reinforcement
Sand loading well or plastic draining board etc.).Then, it is laid with plastic seal film on sand bedding course and its surrounding is made to be embedded in airtight layer top
At least 50cm below face, is allowed to be isolated with atmospheric pressure.Ground inner hole is finally reinforced using vacuum evacuation device (jet pump) reduction
Gap water pressure increases effective stress in its ground, and the soil body is reinforced.(Xia Yubin, Chen Yun are into directly discharging type vacuum prepressing method
The test of reinforcing soft ground and research [J] engineering geology journal, 2010,18(3): 376-383.)
The shortcomings that prior art one
The reinforcement means soil body processing time high for sticky content is longer；When reinforcing, vacuum degree can along soil body depth by
Degradation subtracts, and causes soil body lower part drainage effect poor, secondary treatment is generally required before construction；The reinforcement means processing cost is opposite
It is higher.
The technical solution of the prior art two
Firstly, being inserted into metal electrode on to consolidated subsoil, then pass to direct current.Under electric field action, water body in the soil body from
Anode moves to cathode, and is moved out in cathode, so that reaching reduces high viscosity soil's water content, improves foundation soil strength
Purpose.
The shortcomings that prior art two
The reinforcement means there are metal electrodes it is perishable, interface resistance is excessive, electricity and consumption of electrode are larger the problems such as；Electric osmose mistake
The cell reaction occurred in journey can generate a certain amount of gas, and the spilling of gas will affect consolidation effect；Under independent electroosmosis,
Soil strength non-uniform phenomenon after reinforcing is obvious, and the neighbouring foundation soil strength of anode is significantly larger than the strong of the neighbouring foundation soil of cathode
Degree, the engineering application value that this allows for reinforcing groundwork soil are relatively low.
The technical solution of the prior art three
The reinforcement means is usually using conductive plastics drain bar or conductive plastics drainpipe as the test material of the consolidated subsoil soil body
Material, the draining concretion method that vacuum method is combined with electro-osmosis method, in the collective effect of vacuum preloading draining and drainage by electroosmosis
Lower carry out discharging consolidation, the double effects with vacuum preloading and drainage by electroosmosis.(Fang Yingguang, the vacuum-of xuwei caustic sludge soil
Electric osmose united drainage consolidation characteristics experimental study [J] South China Science & Engineering University's journal (natural science edition), 2006,34(11): 70-
75)
The shortcomings that prior art three
Conductive plastics drain bar used in the reinforcement means is easily bent in vacuum preloading combined with electroosmosis reinforcing process,
And then it will lead to the bad especially later period drainability of drainage effect and be decreased obviously, and plastic draining board is to pass through substrate surface
Groove drained, cannot effectively play the effect of vacuum method draining；In addition, this method is according to conductive plastics
Drainpipe can make the effective electromotive force for acting on the soil body be far smaller than the effective electricity for acting on the soil body when using conductive plastics drain bar

Gu soft soil foundation carries out vacuum preloading combined with electroosmosis processing, part water passes through two pieces of drain bar rows under vacuum
Out, part water passes through the drain bar discharge as cathode gradually to the drain bar migration as cathode under the action of electric field；
S6, closing vacuum evacuation device and power supply described when the intensity of reinforcing soft ground reaches engine request when monitoring.
8. the method according to claim 7 reinforced to soft soil foundation, it is characterised in that: when described to reinforcing soft soil
When the moisture content of ground is reduced to the 70% of initial aqueous rate, power supply is opened, the drain bar being electrically connected with the anode of power supply is as sun
Pole, the drain bar being electrically connected with the cathode of power supply carry out vacuum pre-pressed joint electricity to reinforcing soft ground as cathode, to described
The processing of infiltration method.
