Description
Technical field
The present invention relates to a kind of for disturbing the disturbance drainage arrangement and its construction method of discharging consolidation, in particular to a kind of
The disturbance drainage arrangement and its construction method of movable high-frequency vibration, the disturbance stabilization by drainage suitable for structural soft soil.
Background technique
With the development of China's Tidal Flat Reclamation building cause, especially propose to promote sea in China's " 12th Five-Year Plan " planning outline
After foreign economic development, the requirement for border on the sea land-based area area and development rate is necessarily promoted.And China's Coastal Areas soft clay point
Cloth is extensive, high sensitivity, and engineering properties is poor.Therefore, in the Process of Engineering Construction such as road, sea wall, it is necessary to marine soft soil into
Row is reinforced.
And the natural of the shallow-layer soft clay of the coastal areas crude sedimentation such as the Tianjin in China, Lianyun Harbour, Ningbo, Zhanjiang contains
Water rate is higher than liquid limit, and the engineering accident to come down of collapsing, these engineerings occur frequently for construction of buildings on these Soft Clay Foundations
Accident is similar with the engineering problem that Northern Europe and Canadian stream clay area encounter, and is mainly due to sea and generates into regression
Marine facies structural soft soil.
This is because many marine clays of Deposits in Eastern Coastal China experienced deposition of the sea into period under briny environment, and
It is influenced afterwards in the rear depositional phase by salinity lixiviation, hole water chemistry property is changed.Since salinity subtracts in pore water
Few, liquid limit reduces in crude sedimentation soil, and natural moisture content during salinity lixiviation due to the work of soil structure resistance to deformation
With variation is nearly free from, it is far longer than soil body liquid limit so as to cause natural moisture content, such result necessarily causes to be subjected to salt
The undrained strength of the remodeling sample of the low activity crude sedimentation marine facies structured soils of lixiviation is divided to be greatly lowered, and then significantly
Improve the sensitivity of crude sedimentation soil.Highly sensitive crude sedimentation soil necessarily causes soil structures unstable, and soil structures are unstable
It is fixed, in external environment（Such as building load, excavation of foundation pit, construction disturbance, traffic loading, earthquake load）Under effect, original state
The soil structures of sample are subject to destruction and unstability.
When handling highly sensitive marine facies structured soil ground using conventional discharge concretion technology, necessarily encounters following engineerings and ask
Topic：Natural marine intermediate deposits are in long-term deposition and rear deposition process, the work of the consolidation yield stress of the soil body in time effect
Increased substantially under, with normal consolidation history natural marine intermediate deposits consolidation yield stress be frequently larger than its it is effective on
Cover pressure, imposed load deforms very little when being less than consolidation yield stress, such result is again often such that preloading, vacuum preloading
Quite a few in load is used to overcome the consolidation yield stress of the crude sedimentation soil body, so that foundation stabilization effect is unobvious.
Using the technical solution drained again is first disturbed, the disturbance that the soil body is first carried out with mixing pile machine etc. is needed, then set
Drain bar, and the project cost of this scheme is huge, claim for eot, it is difficult to it promotes and applies.
Therefore according to current actual conditions and technical conditions, a kind of combinable existing plastic drain board flashboard machine is needed
Water discharge technology is disturbed, disturbance effect is obvious, and project cost is cheap, and construction period is reasonable, and makes duration, construction investment, engineering
It being capable of reasonable balance between quality.
