Description

The retaining piles of support pile and composition
Technical field
It is especially a kind of for prefabricated pre- in the engineerings such as pattern foundation pit supporting structure the present invention relates to technical field of building construction The support pile of stress armored concrete and the retaining piles of composition.
Background technique
Pattern foundation pit supporting structure is the safety to guarantee Underground Construction and foundation pit surrounding environment, to foundation pit side-wall and surrounding enviroment Support, reinforcing and the safeguard measure of use.Common foundation pit supporting construction is mainly campshed supporting, wherein with it is more have it is pre- The hollow tubular pole of concrete circular processed, cast-in-situ bored pile and SMW engineering method stake, circular hollow tubular pole it is maximum the disadvantage is that, due to being round Shape can not also form the smooth straight wall in a wall face, the soil pressure shared on every round support pile even if being close to arrangement Power is simultaneously uneven, and whole stress is poor, since round support pile in practice of construction arrange by more difficult complete abutting, water-stagnating effect Also it is relatively difficult to guarantee, so in practice, round support pile is typically all to pull open certain stake spacing arrangement, in the region for needing sealing, One row's water-stop curtain of setting is needed on the outside of round support pile, in addition, circular hollow tubular pole interstitial hole is also easy to produce native plug, and due to face Product is larger, has biggish soil compaction effect in Construction practices, easily causes biggish negative effect to surrounding enviroment.Cast-in-situ bored pile In addition to except the above-mentioned circular hollow tubular pole the shortcomings that, there is also being also easy to produce a large amount of mud, the disadvantage high to environmental requirement.Conventional SMW work Method stake all needs to pull out fashioned iron, increases and pulls out this procedure of fashioned iron, extend the construction period, moreover, fashioned iron pulls out Except effect on environment is big, the gap formed after pulling out to fashioned iron, which blocks, requires height, and the support system no longer has after fashioned iron is pulled out The ability of lateral deformation is resisted, and cost is affected by the duration.
Some undesirable factors are individually present in view of above several support piles, it is mixed successively to occur prestressing force in recent years Solidifying native hollow square pile and H-type prestressed-concrete pile, overcome the above several some drawbacks.But still have it is respective not Foot: although hollow prestressed concrete square pile is close to arrangement and can form a wall that wall face is smooth straight and water-stagnating effect is good, And the contact surface on the inside of wall and foundation pit can form one and block up again directly as basement side wall outer membrane, support pile and basement side wall Wall is closed, but hole is equally easy to produce native plug among it, has biggish soil compaction effect in Construction practices, easily causes to surrounding enviroment Biggish negative effect.And H-type prestressed-concrete pile can not use centrifugation then since itself is in irregular shape in prefabrication process Method production, so the density of its concrete-pile is undesirable;In addition, since manufacture craft is relative complex and cannot utilize hollow Square pile tools and equipment, cost of manufacture and manufacture difficulty are relatively high;It can only be stake especially in actual construction application A short side in two short sides of body and the contact face contact on the inside of foundation pit, by H-type prestressed-concrete pile close-packed arrays at one When the smooth straight wall in wall face, the contact surface of corresponding H-type stake generally only has a quarter of the hollow square pile of prestressing force, connects Contacting surface product it is smaller, and generated when not ignoring piling stake position offset error when, the contact area between this stake and stake will more It is small, therefore H-type stake generally can all pull open certain stake spacing arrangement, this spacing is influenced by construction factor again, it cannot be guaranteed that complete phase Together, the uniform force therefore on the pile more every than the hollow square pile for being linked to be a wall of the uniform force on its every pile is poor and stake Water-stagnating effect between stake is bad.
