A kind of cave type u abutment construction, including basis, abutment body, abutment platform cap, parados and aileron；Wherein, on the basis of abutment body is arranged on, abutment platform cap and parados are set at the top of abutment body, on the basis of be also vertically arranged with two parallel ailerons, abutment body, parados are in contact with aileron；Some cave type constructions are offered on abutment body.The deadweight of abutment will mitigate significantly in the utility model, and the requirement to substrate also greatly reduces, so as to reduce the dosage of the materials such as reinforcing bar, concrete.Abutment steadily of centre of gravity described in the utility model, rational in infrastructure, stress performance is good, while abutment stability is ensured, can solve existing u abutment from the defects of great, material usage is more.
Description
Technical field
It the utility model is related to technical field of bridge construction, more particularly to a kind of cave type u abutment construction.
Background technology
U abutment is widely used in science of bridge building, and it is slightly larger in below 8-11m or span to be especially adapted for use in the depth of fill
Bridge, but the abutment body whole casting concrete in work progress, this can cause the volume of abutment and conduct oneself with dignity it is larger, to substrate
Bearing capacity require it is very high, it is therefore necessary to provide a kind of abutment low to pedestal requirement for bearing capacity.
Utility model content
The purpose of this utility model is exactly to overcome defect present in above-mentioned prior art, there is provided a kind of structure is closed
The u abutment construction for the cave type that reason, stress performance are good, save material, mitigate deadweight.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of cave type u abutment construction, including basis, abutment body, abutment platform cap, parados and aileron；Wherein, abutment body is set
On the basis of, abutment platform cap and parados are set at the top of abutment body, on the basis of be also vertically arranged with two parallel ailerons, abutment body,
Parados is in contact with aileron；Some cave type constructions are offered on abutment body.
The utility model, which further improves, to be, the top of cave type construction is provided with arch ring, and the abutment body back side is provided with
Arch ring for constructing closing to cave type blocks.
The utility model, which further improves, to be, the front end face of abutment body is ramped shaped.
The utility model, which further improves, to be, the gradient of the front end face of abutment body is 10:1.
The utility model, which further improves, to be, bridge block, bridge block side and the back of the body are provided with abutment platform cap
Wall spacing is 5cm.
The utility model, which further improves, to be, basis uses rigid Extended chemotherapy, and the size expanded per side is minimum
0.2~0.5m.
Compared with prior art, the utility model has the advantages that：Due to some using being offered on abutment body
Cave type is constructed, and can save material, and the materials such as reinforcing bar, concrete can be greatly reduced by pouring the cave type construction reserved during abutment body
The dosage of material.Simultaneously so that from heavy and light, reduce requirement of the abutment to base bearing capacity.Cave type construction is adopted in the utility model
Take the mode of vault to ensure that the steadiness of abutment, the bulky abutment of script is seemed slim and graceful attractive in appearance again, enhance bridge
Landscape effect.It can be seen that the utility model mitigate dead load, reduce base bearing capacity requirement, steadily of centre of gravity, it is rational in infrastructure, by
Power is functional, handsome in appearance.While abutment stability is ensured, can solve existing u abutment heaviness, from great, material
The defects of dosage is more.

Embodiment
Below by drawings and examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the utility model includes：Basis 1, abutment body 2, abutment platform cap 3,
Parados 4, aileron 5 and bridge block 6.Wherein, basis 1 uses the construction of Extended chemotherapy, specifically, basis 1 is expanded using rigidity
Basis, the minimum 0.2~0.5m of size expanded per side.
Abutment body 2 is arranged on basis 1, and the top of abutment body 2 sets abutment platform cap 3 and parados 4, and bridge is provided with abutment platform cap 3
Beam block 6, the side of bridge block 6 is with parados 4 at a distance of 5cm.Two parallel ailerons 5, abutment body are also vertically arranged with basis 1
2 back sides, parados 4 are in contact with aileron 5, and aileron 5 and the top surface of abutment body 2 are planar u-shaped；Offered on abutment body 2 some
Cave type constructs 2-1, is provided with arch ring 2-2 at the top of cave type construction 2-1, the back side of abutment body 2 is provided with for cave type structure
The arch ring end-blocking 2-3 of 2-1 closings is made, i.e. abutment body 2 uses back-end closure, the form of front opening.In work progress, abutment body 2 is carried on the back
Face side needs the reserved reinforcing bar being connected with arch ring end-blocking 2-3, is needed after the completion of abutment body 2 pours to the reverse side of abutment body 2
Carry out dabbing processing.In addition, the front end face of abutment body 2 is ramped shaped, the gradient desirable 10 on slope:1, or determined according to actual conditions
It is fixed.
Abutment material usage of the present utility model is few, and from heavy and light, the requirement to substrate is small.
As shown in Figure 5, Figure 6, when the utility model is constructed, abutment body 2 and aileron 5 is poured in basic 1 higher slice, is specifically：
First layer template is first placed, abutment body 2 is reserved the construction 2-1 of cave type, cave type construction 2-1 makes in casting concrete
Reserved with template, its quantity and concrete shape are determined by actual conditions.Second layer template is placed again, pours arch ring 2-2, is encircleed
Circle 2-2 bottoms are connected with cave type construction 2-1, and the back side of abutment body 2 is connected with arch ring end-blocking 2-3.In abutment body back side piece
Stone concrete is sealed, formed arch ring end-blocking 2-3, then pour abutment platform cap 3 and parados 4 successively, finally construct block 6 and
Other constructions.
The utility model can reserve arch to reduce abutment deadweight during abutment body concreting in lifts
Cave type constructs, as cave type u abutment.Constructed using the u abutment of cave type, the platform back of the body can be made to reserve hole, saved
Volume and the deadweight of bridge abutment structure are substantially reduced while material saving.Meanwhile Urban Bridge meet it is safe, practical, economical
While, also of a relatively high to requirement attractive in appearance, the construction of cave type plays very big excellent in terms of the landscape effect of enhancing bridge
Gesture.
