Description
One, technical field
The present invention relates to underground concrete structure and job practices, especially binding anti-slide pile structure and the job practices that combined by the pile cover connection constraints on the stake top by two bored piles.
Two, background technology
1, drill-pouring campshed and piling technique
In present side slope, pattern foundation pit supporting structure, campshed (bored pile) is used more extensive.It is arranged in a straight line by bored pile, and is connected by the contact beam, resists the form of structure of lateral earth pressure or Thrust of Landslide jointly.
Bored pile is to be widely used ripe piling technique.Its advantage is:
Easy construction, because the orifice castinplace pile adopts the rig pore-forming, because the aperture is little, and circular, the therefore general mud off that adopts is made reinforcing cage then, annotates the back concrete perfusion, and operation is simple, and is easy to operate;
Duration is short, need not resemble the retaining wall while excavating of hand excavated pile, therefore saves the duration greatly;
Construction safety, boring needn't resemble the hand excavated pile operation at Ground Operation, operating personnel's operation at the bottom of the stake hole, safety is low;
Be not subjected to season, climatic effect, because Ground Operation, bore diameter is little, be subjected to ooze the influence of soil body stability under the surface water such as rainfall little, can be in the many constructions in season of rainfall.
But shortcomings such as the ability of the anti-lateral load of drill-pouring campshed is low and hindered its use widely.Its shortcoming mainly contains:
From the mechanical property angle, circular stake is used to resist lateral load, is satisfying under the shearing resistance condition, and the ability of opposing moment of flexure is low, and main cause is, circular cross-section be not bending resistance by the power member section, generally adopt rectangle, " worker " shape etc.;
From economic angle, because anti-bending strength is poor, need a large amount of reinforcing bar bending resistances of configuration, material use is insufficient, and is uneconomical;
From safety perspective, amount of deflection is big, because the stake footpath is little, the stake slenderness ratio is big, and cantilevered stake amount of deflection is big, and the stake tension face ftractures easily, the influence stake life-span, and poor durability, thus reduced safety.
Because above shortcoming, make the drill-pouring campshed can only be applied to slope height, foundation depth is little or Thrust of Landslide is little situation, limited its scope of application.
2, rectangle anti-slide pile structure and existing problems
The retaining structure that landslide now, slope project are administered is widely used, is typically the rectangle antislide pile of manually digging hole.To Thrust of Landslide or the big improvement engineering of sliding force, the antislide pile in often first-selected timber pile footpath.
Its job practices: manually digging hole at first, and retaining wall piecemeal; Secondly, make, install reinforcing cage; Placing of concrete.Intensity to be reached just can play the anti-sliding support effect.
Compare the drill-pouring campshed, it has the following advantages:
The square-section antislide pile compares that the circular cross-section anti-bending strength is better, and material use is more abundant, and is more economical; Be subjected to force mode clear, calculate easy.
But this antiskid structure, there are the following problems:
(1) working security is poor;
The major diameter antislide pile, especially the degree of depth is very big, when reaching 30～40m, what adopt still is manually digging hole technology, require the stake hole to satisfy the manually digging hole requirement, add that retaining wall is wide, the stake footpath is bigger, special stake hole supporting retaining wall means need be taked in such hole, hole, as just deal with improperly and may lead to serious accident.
(2) construction period long, be subjected to seasonal effect;
The large-diameter bored pile construction, owing to adopt manually digging hole, the hand excavation amount is big, and efficient is low, and construction seriously is subjected to the influence of earth excavation duration, and the required construction period is long; Meet rainy season, often can not construct, be subjected to seasonal effect big.Administration project to the construction period strictness produces greatly influence.
Three, summary of the invention
The purpose of this invention is to provide a kind of simple and practical, in conjunction with the anti-bending strength of rectangle antislide pile better and advantage, a kind of anti-slide pile structure newly, superior, i.e. binding anti-slide pile structure and job practices such as bored pile construction is safe and simple.
The realization the technical solution adopted in the present invention is:
Structure of the present invention includes and is subjected to piling, tension pile, pile cover, and it is connected with pile cover with the tension pile upper end by piling.
The present invention, it is subjected to piling, tension pile, pile cover all to adopt the reinforced concrete structure with reinforcing cage.
The present invention, it is subjected between piling and the tension pile is 0.1～20cm apart from l.
Job practices of the present invention:
A, construction are subjected to piling: at first adopt rig to hole and become to be subjected to the piling hole, adopt mud off in the boring procedure after, the reinforcing cage handling of making is installed, treat that reinforcing bar cage hoisting is fixing after, fluid concrete pile, stake top reserved steel bar, conventional maintenance;
B, construction tension pile: be subjected to pressing pile construction to finish also conventional maintenance 3～14 days, concrete strength reaches about 30%～70%, the tension pile of can constructing, tension pile is located near being subjected to piling to carry out a hole at side slope or landslide upside, carries out drilling construction then, mud off, then the reinforcing bar cage hoisting of making is fixed, carried out concrete pouring at last, stake top reserved steel bar;
Construction pile cover: after the tension pile construction is finished, can carry out the pile cover construction immediately, two possible surface dust and dregs in stake top of cleaning earlier, the reinforcing bar that reserved by piling and tension pile is connected with the reinforcing cage of pile cover, prop up template again, last concreting, vibrating head vibration compacting, conventional maintenance, stripping.
Advantage of the present invention:
What (1) citation form of the present invention adopted is the Bored Pile Construction method, has inherited its advantage, has construction safety, easy, construction period weak point, is not subjected to the advantage of seasonal climate restriction.
(2) absorbed the good characteristics of anti-bending strength of rectangle antislide pile, because two piles are connected by the constraint of pile cover on the stake top, make it become as a whole common opposing lateral force, internal force shows as a pile pressurized, and a pile tension is subjected to be similar on the force mode rectangle stake.Stress performance is greatly enhanced, and therefore, makes this cluster drill-pouring campshed enlarge the scope of application, can be used in the bigger side slope of lateral force, landslide and pattern foundation pit supporting structure.
