Abstract
The invention creatively provides a method for accurately implanting a large-diameter pile casing into a strong wave flow force inclined bare rock. The method includes the following steps that the tool pile casing is machined, manufactured and installed in place; the tool pile casing is hoisted to the position of a corresponding pile foundation and placed in water until the seabed surface; the position of the tool pile casing is monitored and accurately adjusted; the tool pile casing is inserted and hit; after the tool pile casing enters a rock stratum by a certain depth, a cast-in-situ bored pile steel pile casing is implanted into a hole along the tool pile casing; the tool pile casing is pulled out; the hole is filled with installing guide pipe pouring high-diffusion self-flowing concrete, and then the bottom of the steel pile casing is fixedly connected with the rock stratum. Due to the fact that in the tool pile casing, steel pipe concrete pipes mainly serve as bearing force dowel steel pieces, the water facing and wind facing areas are reduced, impact of tides and wave force on the tool pile casing is reduced, it is guaranteed that the position of the tool pile casing is adjusted accurately, the influence of horizontal resistance on the pile casing can be reduced, the plane position of the large-diameter steel pile casing is effectively controlled, and the steel pile casing is accurately implanted into the rock stratum.
Description
Technical field
The invention belongs to bridge engineering construction technical field, especially relates to the accurate method for implantation of a kind of high-amplitude wave stream power inclined uncovered rock major diameter casing.
Background technology
Under marine environment condition, bridge spanning the sea bored pile construction is in the severe marine environment condition such as strong wind, billow lower time, and major diameter, long steel casing are under the impact of trend, wave during inserted to play, and plan-position control difficulty is large, and casing is difficult to accurate location and installation.Especially sea bed face intectate, the naked scar inclination discrepancy in elevation are large and be located in the granite that intensity is high, adopt the conventional at present construction method of utilizing pile driving barge inserted to play to be difficult to steel casing to be squeezed in rock stratum.
Summary of the invention
The invention will overcome the above problems, provide a kind of high-amplitude wave stream power inclined uncovered rock major diameter casing accurate method for implantation, can reduce the impacts of horizontal resistance on casing such as trend, wave, effectively control the plan-position of Large-diameter Steel casing, and accurately steel casing be implanted in rock stratum.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: the accurate method for implantation of a kind of high-amplitude wave stream power inclined uncovered rock major diameter casing, comprises the steps:
One, by major diameter instrument casing processing and fabricating installation in position;
Two, adopt crane barge that the lifting of instrument casing is transported to corresponding pile foundation position and put into water until sea bed face;
Three, utilize the position of total powerstation monitoring accurate adjustment instrument casing;
Four, adopt hydraulic vibration driver inserted to play instrument casing;
Five, instrument casing enters after the certain depth of rock stratum, and bored pile steel casing is accurately implanted in hole along instrument casing;
Six, instrument casing is proposed;
Seven, install in the high diffusion gravity flow of catheter perfusion Concrete Filled hole, make steel casing bottom fixed with rock stratum.
Advantage and good effect that the invention has are: the accurate method for implantation of a kind of high-amplitude wave stream power inclined uncovered rock major diameter casing, because instrument casing mainly adopts steel pipe concrete pipe as bearing capacity power transmission rod member, reduced to meet water, front face area, thereby having reduced instrument casing is subject to the impact of trend, wave force to guarantee that the exact position of instrument casing adjusts, thereby can reduce the impact of horizontal resistance on casing, effectively control the plan-position of Large-diameter Steel casing, and accurately steel casing is implanted in rock stratum.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is elaborated.
As shown in Figure 1, the applicable instrument casing of a kind of high-amplitude wave stream power accurate method for implantation of inclined uncovered rock major diameter casing, comprise casing main body, cuff 7 and drill bit 4, casing main body comprises a plurality of according to circumferential arrangement and pipe 6 and a plurality of ring 5 parallel to each other, each ring 5 is for connecting a plurality of pipes 6, a plurality of rings 5 distribute along pipe 6 bearing of trends, casing main body two ends are respectively socketed a cuff 7, cuff 7 is the double-layer circular ring structure being comprised of outer shroud steel pipe and the socket of interior ring steel pipe, outer shroud steel pipe and interior ring steel pipe form a toroidal cavity, pipe 6 stretches in toroidal cavity, toroidal cavity and the joint gap fill concrete of managing 6, drill bit 4 is connected with a cuff 7, drill bit 4 comprises tooth head, angle steel and circular interior ring steel plate, one end of interior ring steel plate is connected with the interior ring steel pipe of cuff 7, the other end of interior ring steel plate is along the circumferential direction provided with a plurality of tooth heads, interior ring steel plate outer is arranged with a plurality of angle steel.Pipe is steel pipe concrete pipe.
As Figure 2-3, the accurate method for implantation of a kind of high-amplitude wave stream power inclined uncovered rock major diameter casing, comprises the steps: major diameter instrument casing processing and fabricating installation in position; Adopt crane barge that the lifting of instrument casing is transported to corresponding pile foundation position and put into water until sea bed face; Utilize the position of total powerstation monitoring accurate adjustment instrument casing, because instrument casing mainly adopts steel pipe concrete pipe as bearing capacity power transmission rod member, reduced to meet water, front face area, thereby reduced instrument casing, be subject to the impact of trend, wave force to guarantee that the exact position of instrument casing adjusts; After the accurate adjustment of instrument casing position, adopt hydraulic vibration driver inserted to play instrument casing, because instrument casing bottom is welded with extraordinary tooth head, can enter smoothly sial; Instrument casing enters after the certain depth of rock stratum, by bored pile steel casing 1 in instrument casing is accurately implanted hole 2; Proposition instrument casing; Install in the high diffusion gravity flow of catheter perfusion concrete 3 filler openings 2, make steel casing bottom fixed with rock stratum.
The accurate method for implantation of a kind of high-amplitude wave stream power inclined uncovered rock major diameter casing, adopt steel pipe concrete pipe as the power transmission rod member at the upper and lower two ends of casing, effectively reduced windward, water side, thereby effectively solved, in bored pile steel casing 1 inserted to play work progress, be subject to the impact of trend, wave current power to cause that steel casing 1 plan-position controls, and tilting, in hard naked rock, be difficult to inserted to play and enter the difficulty in rock stratum.The invention has great application value, and its social benefit is good.
Above the invention embodiment is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting the practical range of the invention.All equalization variations of doing according to the invention application range and improvement etc., within all should still belonging to the patent covering scope of the invention.
