Description
Technical field
The present invention relates to construction engineering technical field, especially a kind of assembled arcading wall base pit supporting construction and use
The supporting construction is used for the construction technology of pattern foundation pit supporting structure.
Background technology
In base pit engineering support system will ensure the safety of Underground Construction and foundation ditch surrounding enviroment, at present deep basal pit
Supporting is typically all using the method for conventional drilling cast-in-place concrete pile or concrete underground continuous wall.Drill cast-in-place concrete pile
Generally require separately to set water-stop curtain；Diaphram wall needs larger wall thickness to meet force request, and concrete amount is big, no
The compressive property of concrete can be given full play to.
Domes have incomparable stress performance than other conventional piles, wall construction, and engineers and technicians constantly taste
Examination domes are incorporated into foundation pit supporting project, emerged in large numbers some authorize and just in the patent of invention of publicity, but still have compared with
Big room for improvement.Such as, Xia Xiong et al. discloses a kind of multi-arch type sheet pile supporting construction, but its H pile used with it is concrete prefabricated
Connectionless device between arch piece, does not form complete foundation pit supporting system, it is impossible to and it is independent to be used as an overhang mill, and construct
Middle stake is easy to that the changing of the relative positions occurs with arch piece, or even disconnects, and influences the stress performance and antiseepage function of support system；H pile place
Not only increased expense with watertight rubber band and easily come off in piling construction and cause the decrease of supporting construction water-stagnating effect；It is prefabricated
Arch is vertically connected with mode with convex falcon with groove to be connected, and causes junction shearing strength drastically to decline, turns into weak link.
The content of the invention
The present invention is in place of above-mentioned the deficiencies in the prior art, there is provided a kind of assembled arcading wall base pit supporting construction and
Construction technology.The technical solution adopted for the present invention to solve the technical problems is：A kind of prefabricated reinforced concrete encircles piece, considers arch
The characteristics of tunneling boring of shape structure is pressurized to play concrete material high compressive strength, and a kind of special-shaped " mountain " word piling bar are subject to
Anchor bolt encircles piece to fix Prefabricated Concrete.When foundation ditch is shallower, shaped pile can shape with armored concrete precast arch piece combination construction
Into complete and closing cantilever pile foundation pit supporting system, without setting inner support or drawing anchor.When foundation ditch is deeper, drawing anchor can be added
Or inner support.
Shaped pile is spaced along pattern foundation pit supporting structure position line, and shaped pile cross section is in " mountain " font, is in channel-section steel web
An additional edge of a wing is stretched out in portion.Its web is parallel with pattern foundation pit supporting structure position line during construction；At the edge of a wing of shaped pile left, center, right three vertically
There is the spaced reserving hole of oblong, hole communicates and axis is parallel with stake web, can encircle piece with Prefabricated Concrete and be connected rib
On reserving hole communicate, facilitate bolt connection to carry out fixed arch piece., need to be in shaped pile for needing to set the relatively deep basal pit for drawing anchor
Reserved anchor pole hole is set at web.Anchor pole hole is vertically spaced at shaped pile web, and hole diameter is
200mm, through the middle part edge of a wing and web, 20 ° of the downward squint of its axis horizontal and web oblique.
Vertically there is spaced reserving hole can be with shaped pile on the left and right connection rib of armored concrete precast arch piece
Reserving hole communicates at the edge of a wing, and can be bolted and carry out fixed arch piece.Concrete arch-bar plate top and shape of cross section are H-shaped
Arc-shaped steel pour together, arch piece lower edge has along arch camber line spaced prepared screw-bolt hole hole, the penetrating arch bar of hole.
The arc of H-shaped section arc-shaped steel is identical with arch piece arc, its two side wing edges inner groovy width dimensions and precast arch piece thickness
It is identical, have at arc-shaped steel top flange along the spaced prepared screw-bolt hole hole of arch camber line.When two arch pieces dock up and down, arch up under piece
Portion can be placed in the groove of H-shaped section arc-shaped steel on lower arch piece top, and two arch pieces seamless can then dock.After docking, two
The reserving hole of person communicates, and can be connected with to fix.Watertight rubber band can be set at the top flange of arc-shaped steel in groove to increase
Its strong water-stagnating effect.
By above technical scheme, usefulness of the present invention has：
1, the tunneling boring that Prefabricated Concrete earth-retaining arch piece used in the present invention considers domes is pressurized to play concrete
The characteristics of material high compressive strength, encircle piece reasonable stress, force transmission effect is good.
2, assembled arcading wall base pit supporting construction of the invention, when foundation ditch is shallower, shaped pile and Prefabricated Concrete arch piece group
Complete and closing cantilever pile foundation pit supporting system can be formed by closing construction, without setting inner support or drawing anchor；When foundation ditch is deeper,
Reserved anchor pole hole, another plus anchor pole construction can be set at shaped pile web.Especially suitable for the small inconvenience in space in foundation ditch
The supporting of the deep basal pit of inner support is set.
3, assembled arcading wall base pit supporting construction of the invention uses prefabricated shaped pile and precast arch piece, makes pattern foundation pit supporting structure
Construction period greatly shortens, and construction is more convenient, and can realize the Reusability of component, reduces manufacturing cost.
4, Prefabricated Concrete of the invention arch piece connection rib is fixed on shaped pile groove, because of the close contact of the two three face, then without
Watertight rubber band need to be set also to can guarantee that water-stagnating effect, greatly facilitate construction.
5, the Prefabricated Concrete arch piece connection rib that the present invention designs is in close contact with the face of shaped pile groove three, and is designed with bolt company
Connect, it is ensured that Prefabricated Concrete encircles effective fixation of piece and stake, the hogging piece changing of the relative positions that prevents from constructing influence support system stress performance and
Water-stagnating effect.
6, the present invention be designed with shape of cross section be H-shaped arc-shaped steel come connect up and down precast arch piece, make lower arch piece connect
Connect more closely, strengthen its junction shear resistance.
