Description
Technical field
The invention belongs to architectural design field, more particularly to a kind of overhead transmission line PHC pipe pile foundations foundation pile and cushion cap
Connection structure, the structure have the characteristics that install simple, easy for construction and high capacity.
Background technology
With industry and civil buildings（Including structures）The structure scale of construction and structure height are continuously increased, what basis was born
Load also substantially increases, this proposes requirements at the higher level to foundation connection joint construction reliability.PHC pipe pile foundations have pile body matter
It measures, the significant advantages such as environmental pollution is small, speed of application is fast, mechanization degree is high, is widely applied in Practical Project,
And it is mainly used in the vertical pushing load of carrying.
For bearing the building of larger uplift load and horizontal loading（Structures）Basis, such as overhead power transmission line pole tower
Basis, the connecting structure of PHC pile piles and cushion cap need to carry out primary study in basis.PHC pipe pile foundation foundation piles are connect with cushion cap
When using mode is not cut, traditional connection method need to be welded around pile pile center in pile end board in circumferential equally distributed company
Steel plate is connect, junction steel plate anchors into pile cap steel muscle to weld, and junction steel plate and anchors into cushion cap number of steel bars and specification according to load
Size is calculated, and certain length wadding weft variation is at the same time poured inside pile pile, PHC pile piles are by anchoring into cushion cap reinforcing bar
And the bonding of wadding weft variation and stake inner wall realizes the connection with foundation platform.Overhead transmission line uses PHC pile piles more
Basis does not cut a connection mode with cushion cap, if directly existing in implementation process and centainly asking using above-mentioned Conventional attachment methods
Topic.Such as：Overhead transmission line foundation construction condition is poor compared with other industry and civil buildings, using electric welding junction steel plate and anchor
Enter cushion cap reinforcing bar, construction power supply is difficult to ensure, welding quality cannot be protected completely, and construction site is not easy detection welding matter
Amount；The usually more difficult accurate calculating of adhesion strength design value between wadding weft variation and pile pile inner wall, main cause is in pile pile
Wall is there are one layer of laitance layer, pile pile inner cavity often ponding and inner wall mud cleaning is difficult after piling construction in addition, in addition pile pile
Internal diameter is often smaller, causes wadding weft variation construction environment and quality stability poor, causes wadding weft variation and pile pile inner wall
Between cohesive force it is unreliable, other architectural engineerings determine adhesion strength, but overhead transmission line using field test substantially
Basis is in spot distribution, and Regional Distribution is wide, and orographic condition is totally different, and geological conditions is also multifarious, in very big objective of discreteness
In the case of carry out enough sample sizes and with statistical significance field test it is more difficult.
PHC pile pile pile sinking modes have two kinds of hammering and static pressure, and overhead transmission line is frequently with hammering construction method.Hammering is applied
Engineering method pile head elevation control is more difficult, and traditional foundation pile gos deep into cushion cap bottom surface Reinforcement with cushion cap connection mode for foundation pile
Lower certain length, but this mode need to increase cushion cap bottom surface Reinforcement lower cushion cap concrete when indivedual foundation piles surpass and beat
Thickness realizes the super connection for beating foundation pile and cushion cap, and it is poor to often result in engineering economy in this way, and works as overhead transmission line PHC
When pipe pile foundation foundation pile quantity is more, effective connection of whole foundation piles and cushion cap is controlled to become particularly difficult, in addition each Under Pile
When top mark is high inconsistent, foundation platform bottom longitudinal reinforcement binding constructional difficulties.
When overhead transmission line PHC pipe pile foundations bear to pull out with horizontal loads, foundation pile is born at cushion cap bottom surface
Maximum pulling force, moment of flexure and shearing, section controls PHC pile pile type selectings at this, and any other section often can much meet stress,
If be only meet foundation pile at cushion cap bottom surface stress and increase pile pile section or increase prestress reinforcement, it will cause huge waves
Take.
Invention content
It is an object of the invention to propose the connection structure shape of a kind of overhead transmission line PHC pipe pile foundations foundation pile and cushion cap
Formula, it is intended to which solving cushion cap in above-mentioned background, the connection construction under uplift load effect is difficult with foundation pile and reliability is insufficient, hammers
Pile head elevation control of constructing is difficult, foundation pile is foundation platform bottom surface local location intensity is insufficient the problems such as.
The technology used in the present invention means are as described below.
Present invention firstly provides a kind of prefabricated PHC pile piles, and with pile end board, deformed bar, improvement is：Institute
It is in circumferentially distributed several threaded connection holes to state pile end board and be provided with around pile pile center；Comprising mechanical connecting joint, it includes
There are top connection and lower contact, the top connection lower end has bolt head, the first external screw thread is provided on the outside of the bolt head, described
Inside top connection has the first internal thread；The lower contact upper outside, which is provided with, to be had and the matched second outer spiral shell of connecting hole
Line, the lower contact inside have the second internal thread to match with the bolt head；Comprising pile crown anchor bar, top with
The second internal thread lower thread connection on the inside of lower contact is fixed.
Furthermore：The position of the threaded connection hole is alternatively arranged with deformed bar, and the lower contact defaults in
In the threaded connection hole of pile end board, the pile crown anchor bar is threaded io at lower contact and deformed bar integral preform
Into PHC pile piles.
In this way the advantages of is need not to set wadding weft variation at the top of the PHC pile piles（Containing filling out in-core longitudinal reinforcement and hoop
Muscle）, according to overhead transmission line foundation load feature, cancel wadding weft variation（Containing filling out in-core longitudinal reinforcement and stirrup）When, PHC
Pile pile itself section shear-carrying capacity can much meet stress needs, and the anti-pulling capacity provided can be by connecing
Head is effectively made up, and under the premise of connection safety and reliability is ensured, is reduced site operation difficulty, is accelerated construction
Progress.The mechanical connecting joint needs to be selected according to the principle of equal strength using two sections of compositions, material according to anchor bar stress
It takes, size is adjusted flexibly according to anchor bar stress needs.Mechanical connecting joint hypomere is embedded in pile pile inner wall, can same PHC
Pile pile other materials is in pre-fabricated factory processing and fabricating together.
The present invention is based on above-mentioned prefabricated PHC pile piles, it is further provided a kind of overhead transmission line PHC pipe pile foundation foundation piles
With the connection structure of cushion cap, improvement is：Cushion cap reinforcing bar, spiral hoop are anchored into comprising prefabricated PHC pile piles, foundation platform, pile body
Muscle and cushion cap longitudinal reinforcement；
Wherein, the prefabricated PHC pile piles, have pile end board, deformed bar, and the pile end board is provided with around pile pile center
