Description
Technical field
The utility model is related to the technique of design and construction field of science of bridge building, especially a kind of prefabricated light-weight abutment and brill
The connection structure of hole stake.
Background technology
Abutment in Urban Bridge generally uses light-weight abutment, the abutment body of light-weight abutment to be generally connected directly with drilled pile,
At present mainly based on field cast-in-place, the country is considerably less using precasting process.To promote the full prefabrication and assembly construction of Urban Bridge
Level using prefabrication and assembly construction technique is clearly inevitable requirement for light-weight abutment, researches and develops its crucial connecting structure and construction method
With regard to important.
Invention content
The purpose of this utility model is to provide a kind of prefabricated light-weight abutment and drilling according to above-mentioned the deficiencies in the prior art
The connection structure of stake pours circular hole mode after and realizes connection between prefabricated light-weight abutment and drilled pile, saves scene
Labour, it is environmentally protective, it is fast from site operation speed.
The utility model aim realization is completed by following technical scheme：
A kind of connection structure of prefabricated light-weight abutment and drilled pile, including prefabricated light-weight abutment and drilled pile, it is described prefabricated
Light-weight abutment is supported on the drilled pile, it is characterised in that：Circular hole is poured after being reserved on the prefabricated light-weight abutment, institute
Poured after stating circular hole position correspond to the drilled pile position and it is described after pour circular hole aperture be less than the drilled pile stake
Diameter, is reserved with reinforcing bar in the stake top of the drilled pile, the reinforcing bar be located at it is described after pour in circular hole, pour in circular hole and pour after described
Having built concrete makes the prefabricated light-weight abutment and the drilled pile be connected and fixed.
Be embedded with member in shear memory in the stake top centre position of the drilled pile, the position of the member in shear memory be located at it is described after
It pours among circular hole.
The bottom hole that circular hole is poured after described has poured high strength and no shrinting mortar.
The inner wall that circular hole is poured after described is the inner wall handled through dabbing.
The utility model has the advantages that：1）This province of precasting process be exactly a kind of site operation speed it is fast, it is environmentally protective, save
The high a kind of technique of field workforce, mechanization degree；2）The size of abutment abutment body considers in combination with pier cap beam, saves existing
The cast-in-situ template of field；3）It is a kind of inevitable requirement of the full prefabrication and assembly construction design and construction of bridge that abutment is prefabricated；4）Back pouring hole diameter
It is smaller than pile body diameter, temporary support can be provided for prefabricated abutment；5）There is very big push away in terms of bridge prefabrication assembling
Wide application prospect is apparent using competitive advantage.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the vertical view of Fig. 1.
Specific implementation mode
The utility model feature and other correlated characteristics are described in further detail by embodiment below in conjunction with attached drawing,
In order to the understanding of technical staff of the same trade：
As shown in Figs. 1-2, figure label 1-6 is expressed as：Prefabricated light-weight abutment 1, drilled pile 2, after pour circular hole 3, section
The wet seam 4 of section, member in shear memory 5, embedded bar 6.
Embodiment：As shown in Figure 1, the connection structure of prefabricated light-weight abutment and drilled pile is for prefabricated light-duty in the present embodiment
Being connected and fixed between abutment 1 and drilled pile 2.As shown in Figure 1, prefabricated light-weight abutment 1 is sectional type, in two prefabricated light bridges
It is provided with the wet seam 4 in segment between platform 1, makes two prefabricated light-weight abutments 1 that can be connected and fixed composition one by the wet seam in segment 4
Body.Prefabricated light-weight abutment 1 is erected at the top of several drilled piles 2 and is supported jointly by several drilled piles 2.
As depicted in figs. 1 and 2, circular hole 3 is poured after being reserved on prefabricated light-weight abutment 1, after pour circular hole 3 in prefabricated light bridge
It is reserved in the prefabrication process of platform 1.The quantity and position difference of the quantity of circular hole 3 and the drilled pile 2 of position and lower section are poured afterwards
It constitutes and corresponds.The aperture that circular hole 3 is poured after each is respectively less than the stake diameter of corresponding drilled pile 2.As shown in Fig. 2, every
The stake top of root drilled pile 2 is respectively arranged with embedded bar 6, and the position of embedded bar 6 corresponds to the position that circular hole 3 is poured behind side thereon
It sets, that is, ensures to pour after embedded bar 6 is among the circular hole range of circular hole 3.Meanwhile among the stake top of every drilled pile 2
Position is embedded with member in shear memory 5, and member in shear memory 5 pours the position of circular hole 3 after also corresponding to.Member in shear memory 4 can be used bar reinforcement,
Shaped steel etc..After prefabricated light-weight abutment 1 is set up in place, is poured after and pour non-shrinkage concrete and vibration compacting in circular hole 3, support
Shield, to complete being connected and fixed between prefabricated light-weight abutment 1 and several drilled piles 2.
The present embodiment is in the specific implementation：It pours backward between pouring non-shrinkage concrete in circular hole 3, circular hole 3 can be poured after
Bottom hole pour high strength and no shrinting mortar, to improve the pouring quality of concrete, pour circular hole 3 after especially ensureing and connect with drilled pile 2
The pouring quality for touching position, avoids dead angle, to further increase the bonding strength between prefabricated light-weight abutment 1 and drilled pile 2.
Dabbing processing can be carried out by pouring the inner wall of circular hole 3 afterwards, to ensure subsequently to pour the ungauged regions poured in circular hole 3 backward
The inner wall that the concreting body that concrete is constituted can pour circular hole 3 with after is combined closely, and then is further increased prefabricated light-duty
Bonding strength between abutment 1 and drilled pile 2 ensures to stablize.
Although above example elaborates the design of the utility model aim and embodiment with reference to attached drawing,
But those skilled in the art will realize that in the case where no disengaging claim limits the precondition of range, still may be used
To make various modifications and variations to the utility model, therefore do not repeat one by one herein.
