Description
The present invention relates to a kind of deep foundation ditch double-row pile retaining wall, particularly a kind of double-row pile retaining wall that does not have the superstructure thing.
As everyone knows, high level or super high rise building embedded depth of foundation are big, and construction is complicated.China is since the seventies, and high level and super high rise buildings are built in beginning in a large number, and most of high levels or super high rise building are equipped with basement double as civil air defense constructions and installations.The underground structure part is 1-2 layer, 3-4 layer at most at least.Underground structure is subjected to the buoyancy force of underground water effect on the one hand, is subjected to the side force effect of underground soil on the one hand.And the buoyancy that underground water produces is offset by the gravity of ground highrise building deposits yields, and therefore, the underground structure on the high-rise building mainly is the effect that is subjected to side force.And for no superstructure underground structure partly, it not only is subjected to side force is the effect of overturning or slip resistance analysis power, but also will be subjected to phreatic buoyancy.Thereby the key of underground construction is the foundation ditch retaining wall, in traditional foundation ditch retaining wall is, outer piling structure, it is so-called double-row pile retaining wall, generally have only cap to interrelate between two row's fender piles, so can not form common duty, its overturning or slip resistance analysis (retaining soil) ability, for overcoming the shortcoming of traditional double-row pile retaining wall, what deep foundation construction was both at home and abroad adopted at present is improved double-row pile breast wall technology, Chinese patent CN88100236 is exactly wherein a kind of, its denomination of invention is: " space structures slope protection pile ", this patent are to adopt the steel bar concrete soldier piles as main body, and its top is to link together space structures with the steel bar concrete binding beam.From on the whole stressed, be the cantilever construction form, when two campshed spacings were less than or equal to 2m, preceding campshed was bent, and back campshed only plays the resistance to plucking effect.Still there is following shortcoming in this patent:
1, the stake appearance simultaneously, the foundation ditch retaining wall degree of depth reduces 1/3, when the foundation ditch retaining wall degree of depth was identical, stake was grown to reduce and is added 1/3.
2, can not give full play to inside and outside campshed function separately, the layout of stake is not to give the lateral pressure of stake and the bending moment diagram that forms is arranged by the side direction soil body.
3, can only lateral pressure resistant power, can not anti-floating.
It is pointed out that above-mentioned patented technology do not have the anti-floating device, therefore must set up float Structure on the main body of underground building, this not only gives in the design and has increased trouble, and cost is improved.
The objective of the invention is to design a kind of rational in infrastructure, easy construction, cost is low and have retaining wall and the double-row pile retaining wall of anti-floating function.
Of the present invention the contents are as follows described: it is by low double-row pile, the Y type beam 3 of stud height, interior stake and link ring beam 4 and form, wherein outer campshed 1 height, interior campshed 2 are low, be rigidly connected by linking ring beam 4 between campshed 1 middle and lower part and interior campshed 2 pile covers outside, linking ring beam 4 is stretched in the foundation ditch by interior campshed cap, constitute buoyancy supporting position 41, link Y type beam 3 also is set on the ring beam 4, these Y type beam 3 long-armed upper ends are cemented on the outer campshed 1, its long-armed lower end is cemented in and links on the ring beam 4, and Y type beam 3 galianconism ends then are cemented in outer campshed 1 and the junction that links ring beam 4.
Above-mentioned outer campshed 1 links ring beam 4 by stretching out 200-600mm in the mind-set foundation ditch in the interior campshed 2 than interior campshed 2 high 4-6 rice.The top of campshed 2 pile covers in Y type beam 3 long-armed lower ends are cemented in.
Double-row pile dado structure of the present invention, broken the conventional practice of inside and outside campshed with absolute altitude, make outer campshed 1 than interior campshed 2 height in the design, and be provided with in interior campshed cap absolute altitude position and link ring beam 4, this links ring beam 4 inside and outside campshed is rigidly connected, and prefabricated Y type beam is set linking on the ring beam 4, to improve the rigidity of this tie point, make double-row pile in co-operation to a greater extent, form the form of structure that supports mutually.
In addition, on structure design, make to link ring ring beam 4 one ends by stretching out in the mind-set foundation ditch in the interior campshed 2, form anti-floating support zone 41, promptly set up float Structure, in a word, retaining wall combines with the ingenious of float Structure, makes the present invention have the double action of anti-floating and resistance to capsizing.
The present invention has following advantage:
1. easy construction.The present invention draws anchor and horizontal supporting system owing to having cancelled, and has therefore enlarged mechanical work face in the foundation ditch, and the mechanized rate reaches more than 90%, has reduced and has manually opened volume of earthwork, shortens the construction period greatly.
2. good rigidly is stable reliable.Owing to adopt being rigidly connected between the inside and outside campshed, make its co-operation to a greater extent, integral rigidity is better, and outer campshed 1 cantilever rigidity is less, but can satisfy the requirement of retaining wall function fully, interior campshed cantilever is less, rigidity can fully satisfy more greatly and main body wall between anti-floating tie point construction requirement, through measuring, pile cover ring beam average deformation amount is 21.5mm, maximum deformation quantity is 175mm, but phenomenon of rupture does not take place dado structure.And whole displacement does not take place, prove that its resistance to overturning is reliable.
3. novel structure, anti-floating power is strong.Link ring beam 4 inside and outside campshed is connected effectively, and Y type beam 3 makes inside and outside campshed be formed with certain rigidity in the middle part, co-operation.Novel structure, reasonable in design.Particularly link ring beam 4 and stretch in the foundation ditch, formed extension anti-floating support zone, connect together with building body by interior campshed cap, play the anti-floating effect, cancelled the building body float Structure, thereby reduce the foundation ditch size, improve retaining wall rigidity, save a large amount of human and material resources
