Description
Technical field
The present invention relates to a kind of stake and work progress, particularly a kind of combined type compound pile and construction method thereof.
Background technology
Along with the fast development of urban construction, can be used for the land resources of building fewer and feweri, so building construction develops to high level, various high levels and super highrise building become the leading of current construction.For the Foundation Design of high level and super highrise building, the requirement of foundation bearing capacity is more and more higher, and building settlement deformation requirements is also more and more higher.For meeting bearing capacity and deformation requirements, design often adopts profound large-section in-situ concrete pile pile foundation.
For example, although, still there are many shortcomings: in extensive use in existing preformed pile construction: the collateral resistance performance of soft foundation king-pile week not exclusively; In soft foundation, under vertical compression load, pile strength can not be given full play to; Easily there is not pile body inclining in excavation construction, causes the infringement to pile body at that time; When improper the and pile crown structure of welding procedure is dealt with improperly, producing anti-pulling capacity cannot meet the demands; The problems such as deformation performance is not high enough, fragility destruction.
Existing preformed pile generally be take hammer piling, static pressure pile-sinking and is constructed as main, often also exists soil compaction, influential to peripheral facilities (undreground works, pipeline) in construction; Construction power consumption is high, produce noise and air pollution; While penetrating various interlayer, easily pile body is caused the infringement of macroscopic view or microcosmic during difficult construction wrong; Stake top mark is high-leveled and difficult to control, and cut the improper pile crown that easily causes of stake, destroys or the prestressed variation of pile body; Stake is long restricted, can not meet the problems such as high level or Super High requirement for bearing capacity.In addition, also there is following problem in existing castinplace pile: necking down, and mud emission becomes social concern; Pile bottom sediments etc. happen occasionally, and pile quality fluctuation is stable greatly not; The uneven phenomenon of the high easily generation of stake top mark, during excavation construction, difficulty is large; It is clean and tidy that scene is difficult to keep; Speed of application is slow, and efficiency is low; Folk prescription concrete conversion bearing capacity is only PHC stake 30% to 40%, and it is insufficient etc. that limited resources utilize.
Summary of the invention
Technological deficiency for above-mentioned existence, the object of this invention is to provide a kind of combined type compound pile and construction method thereof, be beneficial to reach energy-saving and emission-reduction shockproof, low noise, pollution-free, pile quality is good, pile extension mode quick and safe is firm, bearing capacity of single pile is high, mud emission is few, has good social benefit and the effect of promotional value.
For achieving the above object, the technical solution used in the present invention is to provide a kind of combined type compound pile, wherein: described combined type compound pile comprises many rectangular pile combinations, many non-prestressed pile tubes, square piles combine, many bamboo joint type pile tubes, square piles combine, the combination of many pile for prestressed pipe, and form the combined type compound pile of multiple piles with different type, the connected mode of every upper and lower two piles of every kind of combined type compound pile is mechanical connection.。
A kind of construction method of combined type compound pile is provided simultaneously.
Effect of the present invention is to compare with existing preformed pile and construction thereof:
Compressive Bearing Capacity of Single Pile is high, concrete strength of pile is not fully exerted, pile body extraction-resistant behavior be largely increased (available mechanical connection), the anti-horizontal bearing capacity of pile body significantly improves, without soil compaction, construction on peripheral facilities without impact, noiseless and air pollution, can pass various interlayers, adapt to bearing course at pile end and change geological conditions greatly; Can not cause the infringement that produces macroscopic view or microcosmic because of pile sinking to pile body; stake top mark height is controlled; can avoid causing because cutting stake the variation of pile crown destruction or pile body compressive pre-stress; pile body; particularly pile body blank area is subject to the protection of the inside and outside cement-soil of pile body; long durability is reliable, and pile body integrity is more reliable simultaneously.
The present invention compares with existing castinplace pile and construction thereof:
Batch production large-scale production, concrete strength can reach C80～C100, pile quality is stable, advanced technology, formation of pile Full-automatic monitoring, reliable construction quality, without cast-in-place concrete, there will not be necking, the stake end, is without sediment, guarantee that end resistance meets design requirement, with mud emission amount under bearing capacity condition, can reduce 70%, social effect is obvious, fast 4～5 times of machine-team speed of application, folk prescription bearing capacity of concrete-filled is high 2～3 times, resource is fully utilized, stake top mark height is controlled, be convenient to mechanical equivalent of light excavation construction, civilized construction, on-the-spot clean and tidy, without on-the-spot screwing steel bars etc., become pile verticality to control well, integrality is more reliable.Accompanying drawing explanation
