Description
Technical field：
The present invention relates to the bored concrete pile and its making construction method of a kind of use ultra-high performance concrete casing.
Background technology：
Deposited reinforced concrete pile basis because bearing capacity is high, settling amount is small uniform, anti-seismic performance it is good and construct in nothing
The advantages of big noise and vibration, it is widely used in the basis of bridge structure.For pile of deep water pile foundation, pile foundation is received
The impact of sandstone in the anxious river degradation of flow velocity and water, easily produces the diseases such as erosion, peeling, dew muscle, reduces making for bridge
Use the life-span；Therefore, in order to improve the service life of bridge, it is necessary to be socketed a casing on the outside of pile foundation to resist river punching
The impact of brush and sandstone.
The content of the invention：
It is an object of the invention to provide the bored concrete pile and its making construction method of a kind of use ultra-high performance concrete casing, knot
Structure is simple, easy construction, effectively improves the service life of bridge.
To achieve these goals, the technical solution adopted by the present invention is：A kind of use ultra-high performance concrete casing
Bored concrete pile, including the pile body of deep water is inserted vertically into, the casing being made up of ultra-high performance concrete is socketed with the outside of the pile body,
Steel reinforcement cage is provided with the pile body, the upper end of the casing is higher by the water surface, and the bottom of the casing is described below riverbed mud face
Pile body and casing are molded using concrete formed by integrally casting.
Further, the internal diameter of the casing and the intended diameter of pile body are identical, and the wall thickness of casing is the 1/ of casing internal diameter
25~1/20, and not less than 2cm.
Further, the casing is made up of the splicing of multiple prefabricated subsections.
A kind of making construction method of the bored concrete pile of use ultra-high performance concrete casing, comprises the following steps：（1）It is prefabricated
Pour casing：The prefabricated casing of ultra-high performance concrete is used according to design requirement；（2）Using mechanical hoisting operating type, will protect
Cylinder is placed at the design attitude of pile body, and the center line of casing is coincided with the center line of pile body；（3）Using pile sinking mode
The lower end of casing is sunk in riverbed, until the bottom of casing is reached 2m below the limiting scour in designed elevation or riverbed
Put place；（4）Steel reinforcement cage is inserted toward casing, and irrigates normal concrete, casing is wrapped pile body and be integrally formed.
Compared with prior art, the present invention has the following effects that：Simple structure of the present invention, easy construction, using by superelevation
The casing that performance concrete is made, can save huge steel consumption, reduce construction costs；Casing is used as the permanent of free removal
Template so that the overall mechanical property of bored concrete pile is good, improves the ability of sandstone impact in the anti-river degradation of bored concrete pile pile foundation and water,
Extend the service life of bridge.
