Abstract
The invention discloses a kind of squeezed concrete stiff composite pile of tubular pole and its construction methods, including peripheral cement earth pile, the squeezed molding Cast-in-place concrete stake of setting in peripheral cement earth pile, prefabricated tubular pile is set in squeezed molding Cast-in-place concrete stake, and the unidirectional valve that stake end seal is closed and can be opened downwards is arranged in the stake end of prefabricated tubular pile.The present invention is easy for construction, and resistance to compression with higher, resistance to plucking, horizontal force resistant performance, stability is good, and integrated degree is high.
Description
Technical field
The present invention relates to a kind of composite pile and its construction methods.
Background technique
There is the problems such as construction is inconvenient, and composite pile system working performance is undesirable in existing composite pile, need further to add
To improve.
Summary of the invention
The purpose of the present invention is to provide a kind of structurally reasonable, the squeezed concrete stiffness of tubular pole easy for construction, that effect is good is compound
Stake and its construction method.
The technical solution of the invention is as follows:
A kind of squeezed concrete stiff composite pile of tubular pole, it is characterized in that: including peripheral cement earth pile, setting in peripheral cement earth pile
Squeezed molding Cast-in-place concrete stake, squeezed molding Cast-in-place concrete stake is interior to be arranged prefabricated tubular pile, and the stake end of prefabricated tubular pile is arranged stake end
Closing and the unidirectional valve that can be opened downwards.
The length of prefabricated tubular pile is greater than, less than or equal to the length of peripheral cement earth pile.
A kind of construction method of the squeezed concrete stiff composite pile of tubular pole, it is characterized in that: including the following steps:
(1) the peripheral cement earth pile of construction,；
(2) unidirectional valve that stake end seal is closed and can be opened downwards is set at pipe pile end；
(3) tubular pole is pressed into peripheral cement earth pile；
(4) after tubular pole is forced into designed elevation, tubular pole is promoted；
(5) while promoting tubular pole, Cast-in-place concrete is perfused from tubular pole inner cavity to stake top absolute altitude, back-pressure tubular pole will be cast-in-place
Between squeezed to the peripheral cement earth pile of concrete and tubular pole, squeezed molding Cast-in-place concrete stake is formed；
Or be repeatedly lifted up tubular pole, back-pressure, and Cast-in-place concrete is perfused from tubular pole inner cavity simultaneously, Cast-in-place concrete is squeezed to peripheral
Between concrete stake and tubular pole, squeezed molding Cast-in-place concrete stake is formed；
When tubular pole is promoted, unidirectional valve is opened downwards；When tubular pole is downward, unidirectional valve closes pipe pile end seal.
The present invention is easy for construction, and resistance to compression with higher, resistance to plucking, horizontal force resistant performance, stability is good, integrated degree
It is high；Intensity is big, and frictional force is big.The bond stress between soil cement and Cast-in-place concrete, tubular pole, frictional force can be increased substantially and bonded strong
Degree is conducive to pile soil common action, or even integration.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of one embodiment of the invention.
Specific embodiment
A kind of construction method of the squeezed concrete stiff composite pile of tubular pole, including the following steps:
(1) the peripheral cement earth pile of construction,；
(2) pipe pile end setting stake end seal is closed and can open downwards unidirectional valve (flap valve provide hinge means with
The connection of pipe pile end or the connection of other suitable methods)；
(3) tubular pole is pressed into peripheral cement earth pile；
(4) after tubular pole is forced into designed elevation, tubular pole is promoted；
(5) while promoting tubular pole, Cast-in-place concrete is perfused from tubular pole inner cavity to stake top absolute altitude, back-pressure tubular pole will be cast-in-place
Between squeezed to the peripheral cement earth pile of concrete and tubular pole, squeezed molding Cast-in-place concrete stake is formed；
Or be repeatedly lifted up tubular pole, back-pressure, and Cast-in-place concrete is perfused from tubular pole inner cavity simultaneously, Cast-in-place concrete is squeezed to peripheral
Between concrete stake and tubular pole, squeezed molding Cast-in-place concrete stake is formed；
When tubular pole is promoted, unidirectional valve is opened downwards；When tubular pole is downward, unidirectional valve closes pipe pile end seal.
The soil cement of formation, squeezed concrete, tubular pole composite pile, including peripheral cement earth pile 1, the interior setting of peripheral cement earth pile are squeezed
Expand molding Cast-in-place concrete stake 2, prefabricated tubular pile 3 is set in squeezed molding Cast-in-place concrete stake, the stake end of prefabricated tubular pile is arranged stake end
Closing and the unidirectional valve 4 that can be opened downwards.
The length of prefabricated tubular pile is greater than, less than or equal to the length of peripheral cement earth pile.
The tubular pole is high-intensitive or intensity adjustable steel pipe tubular pole or hollow square pile；It can be using top as steel pipe tubular pole, lower part
For common tubular pole；
Concrete core (when resistance to plucking requires high, filling out microdilatancy concrete and steel strand wires resistance to plucking) can be filled out inside tubular pole；Concrete in-core can also be into
One step puts steel pipe, steel reinforcement cage, fashioned iron.
Peripheral cement earth pile, Cast-in-place concrete stake, tubular pole three length can be different.
In addition to soil cement diameter is identical with tubular pole diameter, cast-in-place concrete layer can in stake top, stake, stake bottom it is expanding.
