Description
Technical field
This utility model relates to technical field of civil engineering, specifically relates to a kind of implantation rigid pile, imitates without soil compaction
Should, and with the cementitious composite in stake holes, formed stiffness stake.
Background technology
In field of civil engineering, traditional rigid pile includes the construction of prefabricated pile and piling bar, mainly has hammering method and quiet
Platen press, all there is the problems such as penetrating resistance is big, speed is slow, soil compaction is serious in both modes, to week during rigid pile construction
The building on limit, pipeline and structures produce harm.Although taking some Stress Release measures can alleviate the harm of soil compaction, but
Facts have proved that the harm of this soil compaction is difficult to eliminate.Additionally, formation resistance is the biggest, the pressure needing pile sinking is the biggest, causes pile sinking
Process is the biggest to the infringement of pile body.In order to protect pile body to be without prejudice at work progress, it is necessary to use relatively high-bearing capacity
Piling so that the cost of pile foundation increases a lot.Another kind of method is to draw hole drag reduction, this not only adds construction cost, Er Qieyin
Although hole drag reduction, but also reduce the side-friction force of foundation soil, cause the reduction of bearing capacity of pile foundation, thus add engineering and make
Valency.
In mud class soft layer, owing to the frictional resistance of the soil body is relatively low, the side bearing capacity causing pile body is less so that
The intensity of pile shaft material does not plays effect, it is impossible to fully apply, and produces bigger waste.
Rigid pile enters decomposed rock and is currently through dense sand stratum impossible, thus limits the range of application of prefabricated pile.
For the region that surrounding enviroment are complicated, can only use cast-in-situ bored pile, cast-in-situ bored pile will produce in work progress
Raw substantial amounts of slurry coat method and pore-forming pulping, pollute generation environment.Simultaneously as the difficult quality of concrete placed under water
Ensure and the mud skin of drill-pouring pile body periphery causes pile body bearing capacity to decline so that the cost of cast-in-situ bored pile is than prefabricated pile
Cost is high by more than 40%.
Holing in sandy gravel stratum, clear hole is the most difficult, makes the engineering time of cast-in-situ bored pile and cost increase more.
The problem existed based on prefabricated pile basis and bored pile foundation and respective advantage, engineering circles is highly desirable will
The advantage of these two kinds of pile foundations is developed, and overcomes the shortcoming that it exists, and needs a kind of pile foundation construction equipment of innovation.
