Description
Technical field
The present invention relates to the live pouring concrete that stake is built with mould-pipe or other moulds or similar concrete-pile fields, specifically
For a kind of method of sea sand in cleaning PHC pipe pile core.
Background technique
Island or coastal area earth's surface soil property are with sand, flour sand, sandy silt, sand gravel, silty clay and recent shape
At coral limestone etc. based on.PHC tubular pole is used as in the engineering of ground, either using hammering or the construction party of static pressure
Case requires to send PHC tubular pole to the stake top absolute altitude of design, and stake top absolute altitude is substantially below ground surface absolute altitude.Work progress
In be difficult that sea sand is avoided to enter inside PHC tubular pole, and PHC tubular pole and basic junction are substantially all and require stake in-core certain depth
Distributing bar and casting concrete will be arranged in range, to guarantee that PHC tubular pole and basis preferably link together or play resistance to plucking
Effect.And the sea sand cleaning of stake in-core is just at a problem for having to solve.
The sea sand of PHC pipe pile in-core, which is generallyd use, in previous engineering practice holds semicircle frequently with construction personnel
The easy cleaning of cleaning tool bit by bit such as shovel, Luoyang Spade.If PHC tubular pole quantity is few, some manpowers are suitably put into slightly
Micro- consumption some times can complete.But in the large number of heavy construction of PHC tubular pole, if still simple, routine using these
Method needs to put into a large amount of labour, consumption a large amount of time, unit in charge of construction either in terms of the duration or in terms of cost
It is all unbearable, so being badly in need of a kind of to use a small number of construction personnel and can be in a short time by large number of PHC pipe pile
The method that in-core sea sand is cleaned out.
Summary of the invention
In order to overcome the drawbacks of the prior art, provide that a kind of saving operating personnel, to reduce labor intensity, construction efficiency high
Method for cleaning, the invention discloses a kind of methods of sea sand in cleaning PHC pipe pile core.
The present invention reaches goal of the invention by following technical solution:
A method of sea sand in cleaning PHC pipe pile core, it is characterized in that: successively implementing as follows:
A. preparation of construction: prepare water inlet pipe, water pump and reinforcing bar；
B. it blocks: the port on PHC pipe pile core top being blocked with overcover, inlet opening and apopore are provided on overcover；
C. intubation and reinforcing bar: water inlet pipe is inserted into PHC pipe pile in-core chamber by inlet opening on overcover and is inserted into PHC pipe
In the sea sand of stake stake in-core chamber, reinforcing bar is inserted into PHC pipe pile in-core chamber by the apopore on overcover；
D. it fills the water: opening water pump, water pump injects high pressure water to PHC pipe pile in-core chamber by water inlet pipe, and high pressure water rinses
It is flowed out after the intracavitary sea sand of PHC pipe pile in-core by the apopore on overcover；
E. it rinses: continual rinsing, while passing through the sea sand of the apopore insertion PHC pipe pile in-core chamber on overcover with reinforcing bar
Interior discontinuity back and forth plugs, and loosens sea sand；
F. detect: detection borehole cleaning depth reaches the inner sidewall for rinsing PHC pipe pile core after projected depth with clear water；
G. it drains: being extracted out the ponding of PHC pipe pile in-core with water pump.
The method of sea sand in the cleaning PHC pipe pile core, it is characterized in that:
When step a, it is also prepared for outlet pipe；
When step c, outlet pipe is also inserted into PHC pipe pile in-core chamber by the apopore on overcover, reinforcing bar is passed through into water outlet
Apopore of the pipe on overcover is inserted into PHC pipe pile in-core chamber；
When step e, the apopore on overcover is passed through by outlet pipe with reinforcing bar and is inserted into the sea sand of PHC pipe pile in-core chamber
It is interior.
The present invention makes an in-core form one by filling water toward PHC pipe pile in-core and effectively covering at pile crown
Substantially closed space, injects high pressure water and under the agitation of tool in confined space, and sea sand is unique as high pressure water passes through
Water outlet be discharged stake core.A water injection pipe (water injection pipe will be approached or is inserted into sea sand) and one are reserved on pile crown overcover
Water outlet, injects high pressure water toward stake in-core by water inlet pipe, places a root long reinforcing bar in water outlet, starts to infuse at water filling port
When entering high pressure water, while construction personnel uses the sea sand that stake in-core is stirred above and below reinforcing bar in water outlet.Water outlet there are flowing out
When, PHC pipe pile core is discharged in the sea sand in PHC tubular pole together under the agitation of reinforcing bar also with high pressure water.Sea sand
Clear up to design requirement fill out core depth or less after can stop aforesaid operations, be transferred to next root canal pile and continue to clear up.
The present invention solves PHC pipe pile in-core sea sand cleaning hardly possible, wadding weft variation depth is not able to satisfy design requirement
Problem, so that stake in-core sea sand is smoothly clear, wadding weft variation depth is up to standard.Using the present invention, a small amount of construction can be used
Personnel can efficiently solve the problems, such as that sea sand is cleared up in PHC tubular pole in a short time, shorten applying for an in-core sea sand cleaning
The work duration, reduce construction cost.
The invention has the following beneficial effects:
1. changing pure manual operation state；
2. labor intensity of workers is substantially reduced；
3. working efficiency and speed of application significantly improve, conventional method averagely clears up 2 piles for each person every day, and 3 people of the invention are flat
One pile of cleaning can be completed within equal 15 minutes, 30 piles can be cleared up within one day.
4. the present invention efficiently solves during clearing up stake core sea sand, labor intensity of workers is big, and working efficiency is low, construction
Speed is slow, and stake holes inner wall cleaning effect is undesirable, it is difficult to the problem of meeting the requirement of detail design.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
