Abstract
A sheet pile and thin-wall T-shaped pile-combined cantilever support structure comprises a T-shaped pile, a sheet pile and a cap beam, and is characterized in that the T-shaped pile comprises a T-shaped concrete body, a prestressed steel strand and an anti-shear mesh; the sheet pile comprises a rectangular concrete body and a prestressed steel strand; the sheet pile is vertically arranged on the outer side of a flange of the T-shaped pile; the cap beam is arranged on the top of the T-shaped pile and the top of the sheet pile. According to the sheet pile and thin-wall T-shaped pile-combined cantilever support structure, the big-interval prestress T-shaped pile is adopted as an anti-bending and anti-shear component, the advantage of the T-shaped pile can be fully exerted, the deformation is small, and the manufacturing cost is greatly reduced.
Description
Technical field
The utility model relates to geotechnical engineering field, relates in particular to a kind of pattern foundation pit supporting structure or water conservancy embankment technology.
Background technology
While being applied to foundation ditch that digging depth is more shallow or riverbank bank protection, conventionally adopt Form Gravity Breast Wall, its speed of application is slow, poor stability.As adopt the common cantilever setting of supporting pile structure, but cantilever retaining structure is to the bending rigidity of soldier pile with stake is dark requires highly, and the common cost of supporting and protection structure of this form is high especially.And highly larger its bending resistance of T shape stake is strong, while layout as solid matter, its ability can not be not fully exerted, and only widens spacing the advantage of soldier pile is given full play to, and significantly reduces cost simultaneously, but must solve leakage soil and native arching action problem between stake.A kind ofly be out of shape combined support structure little, good economy performance and have not been reported.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of sheet pile of little, good economy performance and cantilever retaining structure of thin-walled T shape stake combination of being out of shape is provided.
The cantilever retaining structure of a kind of sheet pile providing according to the utility model and thin-walled T shape stake combination, comprise the stake of T shape, sheet pile and cap, the stake of described T shape comprises T shape concrete body, prestress wire and shearing resistance net sheet, described sheet pile comprises rectangle concrete body and prestress wire, described sheet pile is vertically arranged at the outside, the edge of a wing of T shape stake, and described cap is arranged at the stake of T shape and sheet pile top.
The cantilever retaining structure of a kind of sheet pile providing according to the utility model and thin-walled T shape stake combination also has following attached technical characterictic:
The embedded depth of described sheet pile is shallower than the stake of T shape.
The bottom of described sheet pile is interval with horizontal bending resistance reinforcing bar by T shape stake one side.
Outside the edge of a wing of described T shape stake, longitudinally level is provided with bending resistance reinforcing bar at a certain distance.
T shape stake one side of leaning on of described sheet pile is provided with piling guiding fastener.
Between described sheet pile, be installed with certain distance.
The cantilever retaining structure of a kind of sheet pile providing according to the utility model and thin-walled T shape stake combination compared with prior art tool has the following advantages:
1, adopt the stake of large spacing Prestressed T shape as bending resistance and member in shear memory, can give full play to the comprehensive advantage of T shape stake, and be out of shape littlely, cost significantly reduces.
2, employing sheet pile, as the member of leakproof soil and transmission passive earth pressure, can expand T shape stake pilespacing, reduces supporting and protection structure reinforcing bar and concrete consumption, and aesthetic in appearance succinct, increases the resistance to capsizing of structure simultaneously.

Detailed description of the invention
Referring to Fig. 1 to Fig. 6, the cantilever retaining structure of a kind of sheet pile providing at the utility model and thin-walled T shape stake combination, comprises T shape stake 1, sheet pile 2 and cap 3, and described T shape stake 1 comprises T shape concrete body 11, prestress wire 12 and shearing resistance net sheet 13.Described sheet pile 2 comprises rectangle concrete body 21 and prestress wire 22, and described sheet pile 2 is vertically arranged at the outside, the edge of a wing of T shape stake 1, and described cap 3 is arranged at the stake 1 of T shape and sheet pile 2 tops.Soldier pile adopts T section, reasonable stress, and concrete is low-consuming.Adopt prestressed high-strength steel strand as main muscle, can save reinforcing bar, bear shearing with shearing resistance net sheet, easy to make, work efficiency is high, the little soldier pile of shearing is without adopting rectangle hoop conventionally; Be arranged at the rectangle sheet pile in T shape stake outside both as bending resistance component, bear the moment of flexure that supporting inter-pile soil produces sheet pile, the following part of its foundation ditch is also passed to native passive earth pressure in the stake of T shape simultaneously.Cap unifies the stake of T shape and sheet pile, makes adjacent studs jointly stressed, cooperative transformation.
Referring to Fig. 1, in the above-described embodiment providing at the utility model, the embedded depth of described sheet pile 2 is shallower than T shape stake 1.The effect of sheet pile 2 is gear soil and transmits passive earth pressure, therefore only under foundation ditch, in certain depth, plays a role, without elongated setting.
Referring to Fig. 4, Fig. 5, in the above-described embodiment providing at the utility model, the bottom of described sheet pile 2 is interval with horizontal bending resistance reinforcing bar 23 by T shape stake one side.The outside, the edge of a wing of described T shape stake 1 longitudinally level is provided with bending resistance reinforcing bar 14.In the edge of a wing of T shape stake and sheet pile, establish horizontal bending resistance reinforcing bar, for bearing the horizontal direction moment of flexure producing when two kinds of stakes interact.
Referring to Fig. 3, Fig. 6, in the above-described embodiment providing at the utility model, T shape stake one side of leaning on of described sheet pile 2 is provided with piling guide card 4.When construction, conventionally first play the sheet piling again of T shape soldier pile, for ensureing that relative position is accurate, piling guiding fastener is set on sheet pile.
