Specific embodiment
Embodiment: in conjunction with shown in Fig. 1-9, for a kind of construction of the aging blocks installation minimally invasive foundation pit structure of elevator provided by the invention
Method, comprising the following steps:
1 primarily determines elevator shaft position in conjunction with original building architectural characteristic according to Design Requirement Drawing, uses professionally test
Survey detector underground structure verify checking and verify, such as encounter in drawing when conflicting underground structure, in time to drawing and
Construction location is finely adjusted, or takes corresponding spare measure scheme.
2 Comprehensive Correlation stakes, pier, well foundation structure three's feature are selected and use pier foundation structure in aging blocks installation elevator,
With the latest equipment drilling device specially designed, punching construction is carried out using taper pier form, it is desirable that drilling pier diameter exists
400-600mm, depth is at 3 meters --- between 6 meters (with specific reference to original building and sub-surface structure, design requirement determines size), and
Pay attention to the protection of pier foundation hole.
It has accomplished fluently after the acceptance(check) of pier hole discharge for 3 pairs and has tied up hanging for steel reinforcement cage or prefabricated steel core pier in advance
It puts, pour pier shaft concrete and conserves, pour pier foundation and select C30 concrete, implanted reinforced bar cage is selected for building
HRB400 grades of screw-thread steel >=14mm.
4 carry out the excavation of foundation pit earthwork according to design requirement, and base compacting is laid with and pads soil layer, and the pad soil thickness >=
100mm, and waterproof layer is laid on top.
5 are laid with two-layer two-way reinforcement and casting concrete formation pier base cushion cap on the waterproof layer, this pier base cushion cap thickness
>=200 are spent, steel bar stress uses HRB400 grades of reinforcing bars, diameter >=12mm in arrangement of reinforcement, and it is straight to be distributed arrangement of reinforcement by spacing 100-200mm
Diameter 8--10mm, spacing 200-300；At pier based platform base position (i.e. at 4 angles), high about 500 high stress steel are reserved
Muscle, casting concrete are C30 concrete；Pier base cushion cap pours completion, reaches requirement flatness and meets design requirement.
6 carry out the short column concrete of casting concrete pier base cushion cap in pier base cushion cap top reserved steel bar, and surrounding pours certain height
The hoistway foundation pit walls concrete of degree；The short column concrete of the pier base cushion cap and hoistway foundation pit walls concrete are poured using being first put into plank and do mould
Method.
7 on pier base cushion cap short column concrete top, and it is short vertical that pre-buried steel construction prefabricated in factory is placed on pier base cushion cap
Steel column is formed on column concrete, the verticality and size for correcting 4 steel columns meet design drawing requirement；Continue to do mould using plank
The method that is poured of method, 300mm at the top of plank height to pre-buried steel column after plank is adjusted, pours C30 concrete
Concrete is fully embedded steel construction in concrete, is embedded to steel construction size in 800mm--1000mm；It is corrected again after pre-buried
The size and verticality of steel construction centainly guarantee that the position dimension of pre-buried steel construction and verticality are requiring error range.?
Can by the short column concrete of production pier base cushion cap and the step for pour 500 hoistway foundation pit walls in the short column concrete of pier base cushion cap it is also straight
It connects and uses pre-buried steel construction instead, step method: 4 Prefabricated steel constructions are placed by figure in pier base cushion cap foundation position, and use bilateral mould
Plate carries out overlay film, and the verticality and size for correcting 4 steel columns meet design drawing requirement；The method for continuing to do mould using plank
The method poured, form height after template is adjusted, pour C30 concrete coagulation to pre-buried steel column top 300mm
Soil is fully embedded steel construction in concrete, is embedded to steel construction size in 1300mm--1500mm or so；It is corrected again after pre-buried
The size and verticality of steel construction centainly guarantee that the position dimension of pre-buried steel construction and verticality are requiring error range.
8 backfill earthwork protective layer compactings, and carry out gutter on the outside of hoistway；Behind equal concrete settings jail, verifying is qualified
Afterwards, plank is removed, earthwork when with earth excavation carries out protection accumulation to hoistway foundation pit periphery, tamps, and form elevator
Foundation pit is highest point, and gutter on the outside of hoistway.
After 9 equal hoistways foundation pit solidifications are solid, the steel superstructure hoistway frame produced in factory, with pre-buried steel construction
Abutting joint is carried out to fix.
Certainly the above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow be familiar with technique
People can understand the content of the present invention and implement it accordingly, it is not intended to limit the scope of the present invention.It is all according to this hair
The modification that the Spirit Essence of bright main technical schemes is done, should be covered by the protection scope of the present invention.
