Description
Technical field
The present invention relates to highway subgrade construction project technical field, more particularly to it is a kind of for the quick prefabricated of highway
Pin-connected panel soft base processing method.
Background technology
China is dispersed with substantial amounts of weak soil, therefore basement process is frequently problem in civil engineering.In recent decades,
Developed rapidly for Soft Soil Subgrade Treatment Techniques, wherein composite foundation technology is most widely used.Typically by matrix（My god
Right foundation soil body or the modified subsoil soil body）With reinforcement artificial foundation dimerous.Under load action, base
Body and reinforcement shared the effect of load.Composite foundation is divided into vertical reinforcement composite foundation and geosynthetic-reinforced mattress is multiple
The class of ground two is closed, and vertical reinforcement composite foundation is divided into discrete material pile（Such as sand pile and broken stone pile）Composite foundation, flexibility
Stake（Such as cement mixing method）Composite foundation and rigid pile（Such as prefabricated pile）Three kinds of composite foundation.Wherein：
Discrete material pile has water penetration, low cost and other advantages, can effectively accelerate ground consolidation rate and reduce sand or
The liquefaction potential of silt foundation, but have that foundation bearing capacity increase rate is limited, settlement after construction big, the shallow-layer under additional stress effect
The problems such as pile body easily expands destruction, the antidetonation for not being suitable for deep liquefied foundation.
Flexible pile has that the construction period is short, low cost, the advantages of larger to the increase rate of foundation bearing capacity, but there is stake
Body low intensity（Below 1MPa）, the shortcomings of anti-horizontal bearing capacity is poor, pile quality is general, be not suitable for the place of deep soft soil foundation
Reason.
Rigid pile（Such as prefabricated pile, cast-in-situ bored pile）It is long with effective length, deform it is small, can give full play to inter-pile soil and
It is the features such as bearing capacity of pile-end soil, maximum to the increase rate of foundation bearing capacity.But there is cost height, quality control in cast-in-situ bored pile
Difficulty processed is big, work progress can produce substantial amounts of mud rubbish, it is high to environmental requirement the shortcomings of；Although and prefabricated pile pile quality
Good, cost is less than cast-in-situ bored pile, but when deep soft soil is constructed, due to the effect for the excess pore water that soil compaction is produced, often goes out
The construction quality problem such as pile body floating after the completion of existing construction of prefabricated piles.
The content of the invention
It is an object of the invention to provide a kind of quick prefabricated pin-connected panel soft base processing method, the soft soil foundation after its processing
