Bn -1 -An -1 is according to this at each form preface stake of plain concrete stake B and the reinforced concrete A preface pilework that the interval set up in the sleeve. The utility model discloses an interlock stake envelope can reach effective location through increasing the concrete guide wall lead to set up in the wall and perforate and increase the sleeve pipe, can be in the work progress construction position of effectual regulation plain concrete stake B preface and the stake of reinforced concrete A preface, the effectual control of ability is simultaneously subsided and is shifted.
Description
Technical field
The utility model relates to a kind of interlocking pile space enclosing structure.
Background technology
Interlocking pile absorbs the plurality of advantages of domestic and international widely used foundation pit enclosure structure form, meet the relevant policies of current national in energy-conserving and environment-protective industry, in today of city Fast Construction development, old town transformation is constantly accelerated, new construction underground obstacle situation becomes increasingly complex, under the background of city land used growing tension, interlocking pile because of its reliable in quality, speed of application is fast, ground adaptability is strong, plane type of attachment is various, construction environmental protection, save the neat feature of cost, outward appearance, its range of application is increasingly extensive.
Because the support form of various foundation ditch is widely different, and the feature of pattern foundation pit supporting structure is that application life is short, belong to a kind of measure structure of engineering construction, therefore the control of cost is generally only paid attention to when designing, deep foundation pit support collapses in recent years, supporting and protection structure displacement causes greatly the cases such as surrounding buildings destruction to happen occasionally, between the campshed that drilling pouring occlusion pile refers to layout, adjacent studs is engaged mutually---and stake circumference is mutually embedding and the steel concrete " piling wall " that formed, and it is used as the deep foundation pit supporting structure of building.Diaphragm wall utilizes various trench machine, by the retaining wall effect of mud, digs out narrow and dark groove, and transfer reinforcing cage in underground, fluid concrete and form one antiseepage, gear soil and the continuous underground wall body of weight-bearing function.
Interlocking pile and diaphragm wall functional advantage are mainly manifested in: (1) reinforcement ratio is lower.Interlocking pile normally adopts reinforced concrete pile and the spaced apart arrangement mode of wet concrete concrete stake, greatly reduces the reinforcement ratio of supporting and protection structure.If this engineering interlocking pile reinforcement ratio is 63.7Kg/m3, and ground-connecting-wall reinforcement ratio is 79.4Kg/m3.
(2) impermeability is strong.Hole-drilling interlocking pile is sequential production, there is not the cold seam of construction and be mingled with earth between stake, and the weak link of the cold seam of construction of diaphragm wall framing joint antiseepage often, once brush wall does not put in place can leave infiltration hidden danger.
(3) flexible during construction, due to modified line of can transferring as required when interlocking pile is constructed, so some planes that are more suitable for constructing changeable foundation ditch and circular arc foundation ditch etc.This engineering is sufficient proof this advantage of interlocking pile also, and because there are 5 protruding parts, place in foundation ditch east side, if use ground-connecting-wall supporting, can increase supporting area, cost increases.
(4) to enter rock efficiency higher for Spiral digging machine, especially constructs in strong-weathered rock and middle weathering lithosphere.In this engineering construction, after Spiral digging machine draws hole, ground-connecting-wall efficiency of construction improves greatly.
(5) slip consistency requires to require slightly lower than ground-connecting-wall, and according to circular characteristic own, self overarches, and has certain effect to preventing landslide.
Interlocking pile should be noted following problem in work progress:
(1) the part construction technology of ground-connecting-wall can being used for reference during construction, as led wall before construction, can effective location be reached.
(2) the front rig of controlling in time of construction is in this stratum work efficiency, lays rig position, rationally arranges the duration, ensure to construct in time both sides reinforced concrete pile after wet concrete forming pile.This is to ensureing that a key of pile body verticality and the rear stagnant water effect of later stage excavation is because of wet concrete.
(3) strict control pile body verticality, and ensure the occlusion size between adjacent studs.Being that shortening is as far as possible empty according to this engineering experience bores portion size, and utilizes rig to rectify a deviation in time in construction.Ensure that pile body is all engaged intact.
(4) once have wet concrete stake inside reinforced concrete pile, be engaged less, do not allow to cut part in steel girder erection process and mould stake, cause this place to mould stake and become " broken pile " phenomenon, bearing capacity reduction.
Utility model content
Because prior art also exists the problems referred to above, the utility model proposes a kind of interlocking pile space enclosing structure, it effectively can solve problems of the prior art.
The utility model solves the problem by the following technical programs:
A kind of interlocking pile space enclosing structure, comprising: the concrete guide wall being located at bottom, is provided with some perforation in this concrete guide wall, and is provided with the sleeve pipe being close to described perforation outer wall in each described perforation; In each described sleeve, build plain concrete pile B sequence stake and the stake of steel concrete A sequence, order is B1-B2-A1-B3-A2-B4 ... Bn-1-An-1, forms spaced plain concrete pile B sequence stake and steel concrete A sequence pilework according to this in each described sleeve.
Described outside of sleeve wall is provided with the spiral lamination that can connect second sleeve pipe.
The bottom of (n+1)th described plain concrete pile B sequence stake is passed through together with concrete coagulation with the bottom of the n-th steel concrete A sequence stake.
Interlocking pile space enclosing structure of the present utility model can reach effective location by increasing concrete guide wall, described lead to arrange within the walls bore a hole and increase sleeve pipe, the construction location of plain concrete pile B sequence and the stake of steel concrete A sequence effectively can be regulated in work progress, simultaneously can effective control settlement and displacement.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with detailed description of the invention, describe the utility model in detail.
Shown in Figure 1, the interlocking pile space enclosing structure of the present embodiment, comprising: the concrete guide wall 1 being located at bottom, is provided with some perforation 11 in this concrete guide wall, and in each described perforation, be provided with the sleeve pipe 2 being close to described perforation outer wall; In each described sleeve 2, build plain concrete pile B sequence stake and the stake of steel concrete A sequence, order is B1-B2-A1-B3-A2-B4 ... Bn-An-1, forms spaced plain concrete pile B sequence stake and steel concrete A sequence pilework according to this in each described sleeve.
Wherein, described outside of sleeve wall is provided with the length that the spiral lamination that can connect second sleeve pipe is convenient to adjust according to physical features situation sleeve pipe.
Pass through, together with concrete coagulation, can gain in strength in the bottom of (n+1)th described plain concrete pile B sequence stake and the bottom of the n-th steel concrete A sequence stake.
Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
