Description
Technical field
The utility model relates to the semi-rigid joint Integral Abutment Bridge of a kind of concrete pile supporting, belongs to bridge field.
Background technology
The horizontal length travel of generation such as temperature, automobile brake of Integral Abutment Bridge superstructure must be received by substructure, and is not suitable for the abutment of rigidity Extended chemotherapy.External application is based on the bridge of H profile steel pile cap.And the consideration in China for economy, abutment foundation is based on rigidity Extended chemotherapy or concrete pile, and piling bar application is few.But the horizontal deformation of concrete pile is starkly lower than piling bar, and very easily ftractures and cause the corrosion of reinforcing bar.
In order to increase the lateral flexibility of concrete pile, some area adopts preboring to expand (Predrilled Oversized) hole method, namely hole (diameter is greater than pile body) in advance in top place, stake position certain depth, after stake is in place, then fill out in the unnecessary space at prebored hole position with loose sand.The object done like this reduces the resistance of soil to the horizontal movement of stake, also namely increases the horizontal flexibility of driven pile.With not establishing the situation of prebored hole to compare, the stake in prebored hole has larger flexibility and less stress, but owing to needing longer stake long, adds construction costs, and can only be applicable to the darker situation of buried bedrock.
As can be seen here, in Integral Abutment, adopt concrete pile, exist in performance with the problem in economy, its horizontal rigidity is comparatively large thus cause the problem of this bridge type longitudinal strain scarce capacity not still to be well solved so far.
Utility model content
In order to solve existing technical deficiency, the semi-rigid joint Integral Abutment Bridge that the utility model provides a kind of concrete pile to support, this architecture enhance the longitudinal strain ability of bridge, add this bridge type and allow that bridge is long, avoid pile foundation to ftracture due to excessive tensile stress, alleviate bridge temperature deformation to damage pile body, ensure that this vertical bearing capacity, extend bridge application life.
The technical solution of the utility model is:
A kind of semi-rigid joint Integral Abutment Bridge of concrete pile supporting, comprise the concrete pile as bearing pile in bridge end carriage, pile cover and insertion earth's surface, it is characterized in that: be provided with the seam that is filled with neoprene between described pile cover and bridge end carriage, the main muscle of described concrete pile runs through this seam and its top is positioned at bridge end carriage.
Wherein, the main muscle top hex nut inserting bridge end carriage in described concrete pile fixes piece of metal plate.
Cuboid concrete has been built in the main muscle periphery being positioned at seam crossing, and the concrete length of described cuboid and width are all the main tendon protective layer thickness of twice, and height is joint gap.
Neoprene is filled in spaces all except main muscle and cuboid concrete in described seam crossing.
In described concrete pile, main muscle is indented bars, and main muscle has part to exceed pile cover and be connected with end carriage, exceeds the symmetrical reinforcing bar that main muscle is major axis or long length of side direction in concrete pile, exceeds pile cover length within the scope of 300 ~ 500mm.
Described concrete pile is oblong profile stake, or is oval, rectangular section concrete stake.
Described seam is arranging a water-proof strip and at its arranged outside one deck fiber waterproofing course near platform back of the body side.
Described seam is wide is 15 ~ 30mm.
The utility model has the advantage of: the utility model enhances the longitudinal strain ability of bridge, add this bridge type and allow that bridge is long, avoid pile foundation produce excessive tensile stress and ftracture, alleviate bridge temperature deformation to damage pile body, ensure that this vertical bearing capacity, extend bridge application life.

Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
As shown in Figure 2, a kind of semi-rigid joint Integral Abutment Bridge of concrete pile supporting, the concrete pile 1 comprising bridge end carriage 3, pile cover 2 and insert as bearing pile in earth's surface, the weak axle of described concrete pile 1 pile body, by curved, adopts varied rigid link to construct with end carriage 3.Described varied rigid link structure refers at pile cover 2 and end carriage 3 seam crossing filling neoprene 5, and is connected both connecting structure by muscle 6 main in concrete pile 1.Varied rigid link between pile body 2 and end carriage 3 constructs the longitudinal strain ability adding bridge, add this bridge type and allow that bridge is long, avoid pile foundation to ftracture due to excessive tensile stress, alleviate bridge temperature deformation to damage pile body, ensure that this vertical bearing capacity, extend bridge application life.
As shown in Figure 1, be the schematic cross-section of concrete pile 1.
As shown in Figure 3, be semi-rigid joint Integral Abutment Bridge end carriage 3 and the pile cover 2 junction detail structure schematic diagram of concrete pile 1 supporting.
As shown in Figure 4, be the semi-rigid joint Integral Abutment Bridge pile cover 2 place schematic cross-section of concrete pile 1 supporting
In the present embodiment, described concrete pile 1 is oblong profile stake, can be elliptic cross-section concrete pile 1-2 and rectangular section concrete stake 1-1, the suitable sectional dimension of concrete pile can be selected, bury quantity and particular location underground, to ensure its vertical support capability and qualification deformability according to type of banketing after platform, pile body loading characteristic and temperature difference size.
