Description
Technical field
The invention belongs to engineering construction technology field, be mainly used in closing on important building and the larger Deep Foundation Pit Supporting Project of risk.
Background technology
In the Excavation Process of city, because foundation ditch periphery exists many existing buildings, and building foundation is darker, so do not allow to put slope excavation, in order to ensure horizontal movement and the sedimentation of stablizing, limiting the foundation ditch periphery soil body of foundation ditch, must adopt suitable foundation pit support plan, in practice, general conventional foundation pit supporting method comprises: (1) campshed Prestressing anchorage cable method.Namely first a placing of reinforcement concrete pile is laid at foundation ditch periphery, the then step excavation soil body, at projected depth place Shi Hanzhang anchor cable, the horizontal movement of restriction hole Zhou Tuti.(2) campshed adds inner support method.Namely first lay a placing of reinforcement concrete pile at foundation ditch periphery, the then step excavation soil body, apply bracing members at projected depth place, the horizontal movement of restriction hole Zhou Tuti.(3) double-row pile method.Namely successively lay the reinforced concrete pile of the suitable spacing of two rows at foundation ditch periphery, and connected by Guan Liang and coupling beam, form the larger overall soil-baffling structure of rigidity with inter-pile soil, the horizontal movement of restriction hole Zhou Tuti.
Above three kinds of foundation pit support plan, all have respective limitation and deficiency: (1) plants campshed Prestressing anchorage cable method, require that surrounding building basis can not be too dark, otherwise anchor cable cannot be constructed; (2) plants campshed adds inner support method, and it is shaping that campshed needs to carry out cast in situs.Inner support requires sleeve configuration foundation ditch, and the direction applying bracing members can not be too wide, otherwise bracing members amount of deflection is too large, and efficiency of construction is lower; (3) plants double-row pile method, and need cast in situs two row, non-assembling, the engineering time is longer, and material can not reclaim and comparatively waste.
Summary of the invention:
This method, based on double-row pile method, adopts assembling, and be a set of comparatively dark mainly for closing on building foundation, the foundation pit supporting method of periphery geological condition complexity, mainly solves following technical problem: the assembling building technology of (1) double-row pile.By arranging drag link sleeve, pull bar, latching connector, make front campshed and rear campshed assemble in aggregates, and conveniently rear campshed is dismantled.(2) recovery technology of coupling beam and rear campshed is solved.Excavation of foundation pit, to be onstructedly to proceed to ± 0 after rear campshed (steel pipe pile), drag link sleeve, pull bar, latching connector are reclaimed, treat that next time, construction still can use above device.
Therefore, adopt this method to carry out pattern foundation pit supporting structure, the globality of supporting and protection structure can be increased, and more cost-saving, increase economic efficiency, effectively shorten the engineering time, increase the safety factor of surrounding building in foundation pit construction process.
The present invention adopts following technological means:
A kind of recovery assembling double-row pile, it comprises front campshed 1, front-seat dowel crown beam 2, rear campshed 3, pile cover 4, drag link sleeve 5, pull bar 6, latching connector 7, reinforcing cage 8, skin of paint 9, bearing pin 10, lockhole 11;
Pile cover 4 is preset on front campshed 1 top, connects between front campshed 1 with hat beam 2.Front campshed 1 is connected with two pull bars 6 and a latching connector 7 respectively with between rear campshed 3, rear campshed 3, is wherein connected by a latching connector 7 between two pull bars 6.Pile cover 4 is all connected with bearing pin 10 with pull bar 6 with pull bar 6, drag link sleeve 5, and lockhole 11 inserts lock pin and prevents drag link sleeve 5 from vertically moving;
Described front campshed 1 is cast-in-place concrete pile; Described rear campshed 3 is steel pipe pile;
One of the present invention reclaims assembling double-row pile, and Specific construction step is as follows: lay double-row pile at the foundation ditch periphery intending excavation, wherein, campshed 1 is cast-in-place concrete pile, rotary drilling rig pore-forming, and stake footpath is 600-1000mm, and pile spacing 2d-3d, d are stake footpath; Rear campshed 3 is steel pipe pile, and stake footpath is 600mm, and pile spacing, stake are long identical with front campshed.Rear campshed 3 adopts rig pore-forming in advance, after penetration concrete, is smeared by pile body in the steel pipe pile patchhole of 3-5mm heat-bodied oil paint 9, campshed after being formed.
Front campshed 1 is 2d-3d with rear campshed 3 array pitch.Front campshed 1 pushes up presets pile cover 4, and connect with hat beam 2 between front campshed 1, concreting is shaping.Lockhole 11 is reserved on rear campshed top, and drag link sleeve 5 is preset on stake top; Front campshed 1 is connected with two pull bars 6 and a latching connector 7 with between rear campshed 3 and rear campshed 3, forms recyclable, assembling, stable Retaining Structure with Double-row Piles.
Excavation of foundation pit, to be onstructedly to proceed to ± 0 after, campshed 3, drag link sleeve 5, pull bar 6, latching connector 7 after reclaiming; After extracting, the stake holes of campshed 3 is tamped after inserting sandstone again.
The present invention, by arranging drag link sleeve, pull bar, latching connector, makes front campshed and rear campshed assemble in aggregates, and conveniently dismantles rear campshed, treats that next time, construction still can use above device.The present invention can increase the globality of supporting and protection structure, and more cost-saving, increases economic efficiency, and effectively shortens the engineering time, increases the safety factor of surrounding building in foundation pit construction process.
