Description
Technical field
This utility model is related to support pile field, more particularly, to a kind of resistance to plucking anticorrosion stake.
Background technology
With the quickening of urban construction, the construction of deep-foundation pit engineering gets more and more, and resistance to plucking problem is also more and more prominent simultaneously.
Further, since general ground is all containing subsoil water, when stake is squeezed into or is pressed in foundation soil, entering underground pile body can be by consubstantiality
The long-pending soil body squeezes to surrounding.Pile peripheral earth natural structure is destroyed, and the hydraulic pressure in soil body hole drastically raises the super hole of formation
Gap water pressure, makes stake float, and all collateral resistances of stake simultaneously and end resistance reduce, and the bearing capacity of stake accordingly reduces.In general, on
Floating the reason is structure body weight and sidewall of basement frictional force sum is less than caused by water buoyancy.Upper floating treatment method is taken out
The cooperation of the methods such as water, decompression, loading and washed-out sand is used, but the structure floating after processing seldom can be returned and is sink to former elevation, remaining
Float-amount need to borrow building later work to process.Through after a while, general weak soil needs several months or longer, and super hole gradually disappears
Dissipate, soil structures are progressively recovered, and the bearing capacity of stake also gos up accordingly.Generally this phenomenon is the time effect of piling.Pile foundation
Technical specification is pointed out, in Deep Thick Soft Ground place, when using sheet intensive have soil-squeezing action stake when, should using effective cut down super
Pore pressure and the measure of soil compaction effect.After stake enters in soil, it is all excess pore water in 0.2mm around stake, this water needs to be up to
Several days or just can disappear (the disappearance speed of various soil layer water is different) to the several months, excess pore pressure and water disappear after stake
One piece can be touched with soil, make stake reach the bearing capacity that design is wanted after contact, but this needs one of time, one
As just can reach the bearing capacity that a stable state and design are wanted all about the time of 3-20 days.But, for
When some engineerings tighter to construction period it is necessary to wait reach the bearing capacity that design needs, just can be to it
Carry out the process of next step construction, waste huge man power and material.
For having corrosivity soil layer, existing square pile does not have corrosion resistant effect, after a period of time is usually used, meeting
Appearance skews, the phenomenon rocked, and this threatens to life security, for not economical during life-time service, needs periodically
Change, waste time and energy, and square pile change after produce waste material can environment be caused necessarily bear.
Chinese utility model patent, Authorization Notice No.：CN201762703U, authorized announcement date：2011.03.16, disclose
A kind of foundation square pile, this foundation square pile has square cross section, on four angles of described foundation square pile, along described foundation square pile
Length direction is twist straggly to be provided with multiple grooves.In this utility model, due to the presence of groove, increased stake and soil layer
Contact area, through calculating, the external surface area of 10% stake can be increased；Increase frictional resistance, be effectively improved resistance to plucking
Power.The another volume of concrete because of geosynclinal concave and then minimizing can reduce 3%, further save cost and decrease the wasting of resources.Its
It is disadvantageous in that, 1) groove in this patent increased the difficulty pouring, and causes cost of manufacture high, long in time limit；2) this patent
For square, the lower dress of inconvenience, base drag is larger.
