Description
Technical field
The present invention relates to a kind of building diaphragm wall, particularly relate to a kind of column supported underground continuous wall that adopts the basement top-down method construction.
Background technology
The building diaphragm wall is a kind of foundation pit supporting system that is applied to a kind of dash soil-baffling structure of contrary sequence method basement structure construction, is the most frequently used a kind of in several Base hole supporting technology of basement top-down method because it has the big and good characteristics of barrier performance of integral rigidity.
In the prior art, multilayer basement of high-rise building and other multilayer underground structures often adopt reverse construction, promptly utilize the building cover structure of basement, comprise that beam, plate, post etc. and external wall structure are as the horizontal support system of foundation pit enclosure structure with go along with sb. to guard him system, contrary sequence method is the boundary with the datum layer, following each layer basement of datum layer constructed from top to bottom, and the construction from bottom to top simultaneously of above each layer of datum layer is so be called contrary sequence method.Because basement top-down method need guarantee that the basement of building has enough horizontal rigidities from top to bottom, foundation pit deformation is very few, therefore, down is arranged at the foundation pit supporting system that bad soil layer keeps off native usefulness by ground when needing to adopt diaphragm wall as construction.
Diaphragm wall need use special equipment to adopt mud off to excavate out a groove with certain width, thickness and degree of depth along deep foundation or the underground periphery of constructing, its thickness reaches 0.6 meter～1.2 meters, the degree of depth reaches tens meters～tens meters and does not wait, and determines according to the designing requirement and the geological condition of building.Reinforcing cage is set in groove, adopt tremie method concreting in mud, build up several meters wide unit wall section, sequence construction successively, the one continuous underground reinforced concrete wall that unit wall section is connected into certain jointing method, so that antiseepage during excavation of foundation pit, retaining soil, as the supporting on adjacent structure basis and the part that directly becomes the foundation structure of bearing direct load, diaphragm wall will be constructed than in the dark rock stratum more than 2 meters of basement bottom board usually.Its weak point is:
(1) because construction of diaphragm wall needs large-scale special-purpose machinery, and the groove section generally adopts brill, piercing and shaping die, mud off, the cost of operating expenses is higher.
(2) diaphragm wall in hard soil layer and rock stratum, excavate grooving difficulty, particularly rock stratum to bury more shallow be geological conditions when better, and be under the situation of multi-storey basement, the increase of going into rock is very expensive, the construction costs increase is bigger.
(3) being closely connected owing to diaphragm wall and contrary sequence method technology; the cost height of diaphragm wall directly influences basement top-down method The Application of Technology and popularization; but how in the safety of guaranteeing base pit engineering reduction of erection time again; simultaneously again can the Control Engineering cost, become the key issue that influences the contrary sequence method technical development.
Summary of the invention
But the object of the present invention is to provide and a kind ofly guaranteeing under the security situation of base pit engineering not only reduction of erection time but also column supported underground continuous wall that can the Control Engineering cost.
The present invention is a kind of column supported underground continuous wall that adopts the basement top-down method construction, comprise the underground wall body that is provided with along the basement periphery, it is characterized in that described underground wall body is made up of shallow body of wall and dark body of wall, described shallow body of wall is positioned at the top of diaphragm wall, has common diaphragm wall wall body structure, form the closed type body of wall along the basement periphery, retaining soil, dash, impervious when being used for the basement top-down method construction; Described dark body of wall is positioned at the below of shallow body of wall, with discontinuous manner the post that post props up formula embedding rock section is set and props up body of wall, is used to support shallow wall section and as basement floor vertical support structural element, can effectively controls the vertical deformation of diaphragm wall superstructure.Because shallow body of wall has reduced the height of diaphragm wall, dark body of wall post props up body of wall and has reduced the quantity that cost height, diaphragm wall that difficulty is big are gone into the dike section, thus reduction of erection time and reduce cost (referring to Fig. 2,3) greatly.
The present invention is divided into shallow body of wall and dark body of wall two parts with diaphragm wall, shallow body of wall at bad soil body position still adopts existing continuous underground wall structure, dark body of wall at the good position of geological conditions then no longer adopts diaphragm wall structure of the prior art, but having adopted the interruption wall construction, this technical scheme is to be based upon on the basis of the two big characteristics that basement top-down method has to realize.Described two big characteristics are: (1) has the existence of soil arching effect; (2) inner support of contrary sequence method diaphragm wall is protected, and promptly the overall structure of diaphragm wall, floor beam, plate and post formation is utilized its lateral rigidity, and the foundation ditch lateral earth pressure is played a stronger fixed level support effect.At large the technology of the present invention and notion are carried out a large amount of Finite Element Numerical Simulation analyses and monitored data checking and practical engineering application practice through system, confirmed feasibility of the present invention.
When basement top-down method is constructed, what construct at first is basement diaphragm wall all around, while is in relevant position (pillar or the partition wall intersection etc. of interior of building, calculate to determine as required) build or lay the intermediate support stake and post bore the superstructure deadweight and executes the support of load down as construction period before the base plate back cover, after diaphragm wall and the pile completion just from top to down successively carry out the construction of excavation of foundation pit and floor beam, plate.The beam slab floor structure of elder generation's construction datum layer, the first road horizontal support on the diaphragm wall top around forming, the significant horizontal rigidity of floor structure becomes the very big support of diaphragm wall, utilize diaphragm wall retaining soil subsequently, successively earth excavation and build each layer underground structure downwards until the base plate back cover.In this work progress, no matter whether underground diaphragm wall is added interim horizontal support with the soil pressure of balanced action on diaphragm wall, when whenever finishing first floor bent cap plate, the capital makes diaphragm wall form many one horizontal supports, make the inner support of diaphragm wall be protected, be that diaphragm wall, floor beam, plate and pile have formed an overall space structure that rigidity is huge, can play a stronger fixed level support effect the lateral earth pressure that acts on the diaphragm wall.
Although the geological condition of each building operations all is not quite similar, but the geological conditions of common buildings construction just comprises two parts soil body nothing more than, the part soil body is the bad soil body that is positioned at the ground table top, moisture water permeability is stronger, the soil is porous, represents the angle of internal friction α (referring to Fig. 1) of soil body stability less, when carrying out excavation of foundation pit in the mode of opening wide, cause soil body landslide easily, the angle on landslide and the angle of internal friction α of this soil body match.Miscellaneous fill layer, mud, layer of sand, plastic farinose argillic horizon etc. all belong to the bad soil body.Another part soil body is the good soil body that is positioned at bad soil body below, and soil (rock) matter is closely knit, and intensity hardness is higher, and bad hydraulic permeability is even not permeable, and angle of internal friction α is bigger, generally is severely-weathered to middle weathered rock formation and gentle breeze rock stratum.The degree of depth of the bad soil body of different regions can be different, and according to China's north and south geology difference condition, depth difference southern, the northern bad soil body can reach 20～30 meters more than, and the degree of depth of the southern bad soil body is less, and the degree of depth of the northern bad soil body is bigger.
When basement top-down method is constructed, be positioned at the bad soil body on foundation ditch top, owing to the basement overall structure that has diaphragm wall and flooring beam slab, pile etc. to form, its rigidity is huge, is enough to the slippage that stops that soil layer produces.Therefore, the sliding rupture of the foundation pit side-wall at bad soil body position is almost non-existent.And when soil (rock) layer position continuation preferably excavated downwards, the below soil body of excavation is not as the supporting-point of the soil mass of foundation pit of exposing out, the top basement of rigid body formula is then as foundation ditch upper support point, can in the excavation face soil body, form soil arching effect (referring to Fig. 4) after the last lower support, make that the soil pressure that acts on this position space enclosing structure is less with joint efforts, can play the effect that stops unsupported soil body slipping, protuberance.In suitable altitude range, adopt present technique, can reasonably utilize the physical characteristic of better soil layer itself to reach homeostatic effect, retaining soil to this position requires just can reduce greatly, if what enter is not weathering or gentle breeze rock stratum, even can consider to keep off native requirement, adding need not have the sealing requirement after entering waterproof soil (rock) layer yet, diaphragm wall at this position in fact only plays load-bearing, so, just need not the equal build-in of all wall sections and go into hard soil layer, only need post to be set and prop up body of wall with certain spacing, can realize the effect of its load-bearing and vertical supporting member, save most of conventional retaining wall member at this position and become possibility thereby make.
