Abstract
The utility model discloses a kind of Bridge Piles, and sleeve and bridge to be protected to exempt to dig pile crown in advance, and problem is dug for solving bridge pile head.The bridge exempts to dig pile crown; including bridge struction pile pile body; pile crown main reinforcement is provided in bridge struction pile pile body; it is characterized in that; it is nested with a protection sleeve respectively in every pile head main reinforcement; the protection sleeve includes sleeve part and plate part; the sleeve part outer surface is smooth structure; inner surface has several annular projections; multiple closed spaces are formed between the sleeve and pile crown main reinforcement; the plate part profile is triangle or sector, and tomography is formed in pile crown part after all plate parts enclosings.The use of the protection sleeve simplifies the problem that pile crown cracks, and improves speed of application, and can have very high practical value to avoid the injury caused by pile crown.
Description
Technical field
The utility model is related to bridge concrete pile construction technology field.
Background technology
It is an important process in bridge construction process to abolish bridge pile crown.Construction technology road referring to figs. 1 to Fig. 3
Line, according to production engineering specifications, the top mark height of bridge struction pile should be above 0.5 meter to 1 meter of designed elevation.For example, design rule
One 13 meters of concrete-pile will be played by drawing, and it is 13.5 meters to need the height poured, and then extra 0.5 meter is cut again.
This is because during casting concrete, in stake hole, stone has sedimentation phenomenon so that stone in upper 0.5 meter of part section
Content is less, forms mortar section, does not meet intensity requirement, so, it must be accorded to cut during construction in later period.Current stake
Head cuts method and is：It is abolished using cutting machine, it is big that there are labor intensity, and speed of application is slow, the problem big to shape body reinforcing bar damage.
Utility model content
In order to solve the deficiencies in the prior art, a kind of Bridge Pile of the utility model offer protects sleeve and bridge to exempt to dig stake in advance
Head, for solving the problems, such as that existing concrete-pile pile crown abolishes hardly possible.
Technical solution is used by the utility model solves its technical problem：
Bridge Pile protects sleeve in advance, is moulding, which is characterized in that including sleeve part and plate part, the sleeve
Partial outer face is smooth structure, and it is triangle or sector that inner surface, which has several annular projections, the plate part profile,.
Further, it is designed at least one fin in the outer surface of sleeve part, the fin is vertically arranged.
Further, the sleeve part and plate part are arranged substantially perpendicular to each other.
Bridge exempts to dig pile crown, including, including bridge struction pile pile body, pile crown master is provided in bridge struction pile pile body
Muscle, which is characterized in that be nested with a protection sleeve respectively in every pile head main reinforcement, the protection sleeve include sleeve part with
Plate part, the sleeve part outer surface are smooth structure, and inner surface has several annular projections, the sleeve and pile crown master
Multiple closed spaces are formed between muscle, the plate part profile is triangle or sector, after all plate parts enclose
Tomography is formed in pile crown part.
Further, it is designed at least one fin in the outer surface of sleeve part, the fin is vertically arranged.
The utility model has the beneficial effects that：
The protection tube-in-tube structure is simple, and the protection sleeve cost that with mass production, can be molded material is less than 1 yuan of people
Coin, relative to construction cost, sleeve cost can be ignored.
The use of the protection sleeve simplifies the problem that pile crown cracks, and improves speed of application, and can be to avoid to pile crown
Caused by injure, have very high practical value.With reference to embodiment to the convenience for construction of the utility model and beneficial to effect
Fruit is described further.

Fig. 9 is the principles of the present invention figure.
Figure 10 is the stereogram of two middle sleeve of embodiment.
In figure：100 sleeves, 110 sleeve parts, 111 annular projections, 112 fins, 120 plate parts
200 positioning cards,
000 main reinforcement, 010 concrete, 020 pile crown part.
Specific implementation mode
With reference to figure 4 to Fig. 7, Bridge Pile protects sleeve 100 in advance, using the injection structure of plastic material, have it is cheap, be easy to
The characteristics of molding, including sleeve part 110 and plate part 120,110 outer surface of sleeve part are smooth structure, inner surface tool
There are several annular projections 111, the internal diameter of annular projection 111 is slightly larger than the diameter of reinforcing bar, when being nested on reinforcing bar, annular projection
It is formed and is contacted between steel reinforcement cage main reinforcement, formed multiple closed spaces between sleeve and steel reinforcement cage main reinforcement, avoid cement bonded sand
Slurry enters, and is conducive to subsequent pile crown and rejects technique.
Plate part 120 is integrally formed, plate part generally triangle or sector, when multiple sets with sleeve part
When cylinder is centered around steel reinforcement cage upper end, multiple plate parts are similar to circular structure around forming one, with reference to figure 8, due to flat
Plate part 120 is the plastic plate with certain elasticity, has the function of evacuation, after pouring, plate part in the stage of pouring
120 gradually restore horizontal component, and after concrete hardness reaches design hardness, the presence of level board can be with one formed here
Horizontal tomography can be broken, it is then possible to which pile crown is removed when there is external impacts at this tomography.
Bridge exempts to dig the construction of pile crown, includes the following steps：
The first step, the steel reinforcement cage main reinforcement part that will be above stake top elevation line put on this sleeve 100, and the master in portion under a bushing
It is limited using positioning card 200 on muscle 000, prevents its slide downward, wherein positioning card 200 is fastened on sleeve and steel hoop
Between, length is predetermined length, with reference to figure 9.
Second step, stake of casting stake hole in casting concrete 010；Etc. pile foundations concrete intensity reach 70% after, excavation is held
Stylobate is cheated, and in cushion cap digging process, cannot damage and be bent main reinforcement.
Third walks, after concrete setting is cheated in stake, and iron chock is driven into pile crown part 020 along sleeve plate part
In, iron chock is tapped with iron hammer or mechanical equipment, until pile crown detaches crack with pile body generation；
4th step fixes drill rod on pile crown, the pile crown cut is hung pile body by hoist engine lifting rope, you can complete
At.For pile crown part, it can carry out removing and crack processing.
Embodiment two
As further extension program, with reference to figure 10, one or more wing is designed in the outer surface of sleeve part
Piece 112, fin is vertically arranged, the presence of multiple fins, can form multiple cut zone in vertical direction, after pile crown separation,
During cracking pile crown so that pile crown is more prone to crack, and reduces construction cost.
Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, relevant technical staff in the field is to this
The various modifications of utility model and improvement should all expand in the protection domain as determined by the utility model claims book.
