Description
Technical field
The utility model is related to a kind of civil engineering pile top, more particularly to a kind of novel expansion pile head pile top component.
Background technology
Pile top is a kind of component for pre-stressed concrete pipe pile foundation construction, and it is arranged on pile tube foremost,
It is arranged in pipe pile head during pile tube sinking construction, plays guiding and plugging action.In engineering construction of prefabricated piles, pile top is welded on stake
Head position, band pile body enters underground layer, in order to avoid cause pile crown to destroy and pile body inclining (degree control), and can preferably into holding
Power layer.Existing pile top is small due to its lifting surface area, when pile top enters into the soil layer of certain depth, because stress constantly increases,
It is easily caused pile top disconnected, broken；Secondly, existing pile top inconvenience transport.In order to solve the problems, such as prior art, people are carried out
Long-term exploration, it is proposed that solution miscellaneous.
For example, Chinese patent literature discloses protection pile top, [application number：201520380419.4], including pile, pile
Interior to be vertically provided with location-plate, location-plate is fixed on pile, the built-in locating dowel of location-plate, and locating dowel top extends in pile top
On portion's lateral surface, piles column bottom connects a pile top, is connected by a changeover portion between pile top and pile, and locating dowel is each passed through stake
Post and changeover portion are extended in pile top, and locating piece is provided between pile top and pile, and pile top is horizontally installed with horizontal stroke at pile
Beam, crossbeam two ends insertion is arranged on the inwall of pile top two, and pile top is horizontally connected with backplate at bottom, between backplate and pile top
It is fixedly connected, the built-in reinforcement of backplate, reinforcement two ends both pass through backplate and are connected with pile top.Program penetration power is strong, overall knot
Structure is good, and site operation row is strong, and connection is quick, preferably pile top can be combined together with pile, it is adaptable to different engineerings with
The need for geological conditions, construction utilization rate is substantially increased.
Although above-mentioned scheme has many advantages, such as the above, the program at least also has the following disadvantages：Design is not
Rationally, the lifting surface area of pile top is small, and when necessarily deep soil layer is entered into, pile top is easily disconnected, broken；Secondly, transport is inconvenient.
Utility model content
The purpose of this utility model is directed to above mentioned problem, there is provided a kind of design is more rationally and the new expansion that is readily transported
Major part pile top component.
To reach above-mentioned purpose, the utility model employs following technical proposal：This novel expansion pile head stake component, including be in
The enlarged footing pile top of taper, and it is arranged on enlarged footing pile top end and the barrette being connected as a single entity structure with enlarged footing pile top
Body, is provided with the deep gouge to the inner depression of square pile body on the upper surface of square pile body, is provided with described deep gouge and is vertically arranged
And in shaft-like prefabricated pile, described prefabricated pile is connected in the deep gouge of square pile body by Detachable connection structure.
In this application, by setting above-mentioned enlarged footing pile top, because the lifting surface area for increasing pile top is big, pile top is worked as
The end resistance between end and soil is increased after into supporting course, bearing capacity of single pile is effectively raised；Secondly, the pile top compares stake
Body section is big, and rigidity is more than pile body structure, favorably passes through harder soil layer, reduces broken pile, the probability of broken stake, designs more adduction
Reason；Secondly as prefabricated pile is connected with square pile body by Detachable connection structure, its construction and transport more facilitate.
In above-mentioned novel expansion pile head stake component, described Detachable connection structure is arranged on prefabricated pile bottom including some
The mounting hole in portion, the fixing hole for being corresponded with mounting hole and being set is provided with the bottom land of deep gouge, and described prefabricated pile is by some
Fastener is connected in deep gouge.
In above-mentioned novel expansion pile head stake component, described deep gouge section is square.
In above-mentioned novel expansion pile head stake component, the groove depth of described deep gouge is less than the height of square pile body.
In above-mentioned novel expansion pile head stake component, described prefabricated pile is square prefabricated pile.
In above-mentioned novel expansion pile head stake component, described enlarged footing pile top cone angle scope is between 40 ° -140 °.
In above-mentioned novel expansion pile head stake component, described mounting hole has 2-6.
In above-mentioned novel expansion pile head stake component, described mounting hole has 4.
In above-mentioned novel expansion pile head stake component, 4 described mounting holes are evenly distributed in deep gouge.
In above-mentioned novel expansion pile head stake component, described fastener is expansion bolt.
Compared with prior art, the advantage of this novel expansion pile head stake component is：
1st, by setting above-mentioned enlarged footing pile top, because the lifting surface area for increasing pile top is big, when pile top enters holding force
The end resistance between end and soil is increased after layer, bearing capacity of single pile is effectively raised
2nd, the pile top is bigger than pile body section, and rigidity is more than pile body structure, favorably passes through harder soil layer, reduce broken pile,
The probability of broken stake, it is more reasonable to design；
3rd, because prefabricated pile is connected with square pile body by Detachable connection structure, its construction and transport are more square
Just.
4th, simple structure, it is easy to manufacture and with low cost.
