Description

Technical Field

[0001] The present invention relates to the construction of correcting the deviation of inclined PHC pipe piles, and particularly to a construction method for synchronously correcting the deviation during the driving of super-long and large-diameter PHC inclined piles. Background Art

[0002] As a kind of precast pile foundation with excellent performance, PHC pipe piles are widely used in engineering construction. Traditional pile foundations are mainly vertical structures. During construction, PHC precast pipe piles are driven into the soil body through a pile-driving device. However, with the needs of engineering construction, inclined pile foundations have emerged, which pose new requirements for traditional pile-driving devices and construction technologies. With the development of construction technologies, inclined pile-driving devices have emerged. However, due to the great difficulty of inclined pile-driving operations, compared with vertical pile-driving, situations such as inclination and deviation are more likely to occur; therefore, it is necessary to correct the deviation of the inclined pile foundations.

[0003] The main conventional deviation-correcting measures are as follows: ① Excavating the soil on the reset side for unloading; ② Applying a horizontal thrust to the pile foundation on the reset side. However, the applicable scope of the above measures is limited and is only applicable to the situation where the pile foundation is not driven deep and the deviation is not large. In addition, when using the above methods to correct the deviation, it is necessary to stop the pile-driving operation, and then carry out the pile-driving operation after the deviation correction is completed, which seriously affects the construction efficiency. Therefore, during the construction of super-long and large-diameter inclined piles, both the pile-driving difficulty and the deviation-correcting difficulty of the pile foundation are very large, and there is an urgent need to develop new construction technologies to ensure the construction quality of super-long and large-diameter PHC inclined piles. Summary of the Invention

[0004] The purpose of the present invention is to propose a construction method for synchronously correcting the deviation during the driving of super-long and large-diameter PHC inclined piles in view of the problem of pile foundation deviation correction existing during the driving of super-long and large-diameter PHC inclined piles. To achieve the purpose, the technical solution of the present invention is as follows:

[0005] The construction method for synchronously correcting the deviation during the driving of super-long and large-diameter PHC inclined piles involved in the present invention includes the following steps:

[0006] Step 1. Fabricating a precast deviation-correcting pile head. The precast deviation-correcting pile head mainly consists of a circular side plate, an annular wing plate, a conical bottom plate, and a limiting plate. The conical bottom plate is welded to the bottom of the circular side plate, the annular wing plate is welded to the outside of the circular side plate, and the limiting plate is welded inside the circular side plate.

[0007] Step 2. Manufacturing of the deviation rectification control system: Install and fix a central screw on the upper surface of the base, install a lead screw motor on the central screw, and hinge one end of two movable support rods to the lead screw motor and the base respectively, and hinge the other end of the movable support rods to the support plate; Install a biaxial dynamic inclination sensor on the side wall of the base; Install and fix a rotating motor on the lower surface of the base, and fix the rotating shaft of the rotating motor to the bearing plate; Weld limit channel steels on both side surfaces of the bearing plate, insert the upper and lower ends of the deviation rectification wing plate into the limit channel steels, and install a hydraulic telescopic rod between the bearing plate and the deviation rectification wing plate, and hinge both ends of the hydraulic telescopic rod to the bearing plate and the deviation rectification wing plate respectively.

[0008] Step 3. Measure and lay out the position of the pile foundation, excavate a pile hole on the ground, install a guide sleeve in the pile hole, set steel bars outside the guide sleeve and pour a concrete retaining ring to fix the guide sleeve.

[0009] Step 4. Place the deviation rectification control system into the PHC pipe pile from the lower end of the PHC pipe pile, then control the lead screw motor to move downward along the central screw, so that the support plate expands outward until it closely adheres to the inner wall of the PHC pipe pile, and temporarily fix the deviation rectification control system in the PHC pipe pile; Then install the prefabricated deviation rectification pile head at the lower end of the PHC pipe pile, insert the circular side plate into the PHC pipe pile, and insert the two vertical side edges of the bearing plate into the gaps between adjacent two limiting plates respectively.

[0010] Step 5. Lift the PHC pipe pile and place it on the pile driver, adjust the inclination angle of the pile driver to align the pile body axis with the design axis, and then slowly lower the lower end of the PHC pipe pile into the guide sleeve.

[0011] Step 6. Hammer the PHC pipe pile through the pile hammer to implant the PHC pipe pile into the soil body; During the hammering process, real-time monitor the pile body axis through the biaxial dynamic inclination sensor. If the pile body axis deflects relative to the design axis, rotate the prefabricated deviation rectification pile head through the rotating motor to make the deviation rectification wing plate perpendicular to the plane where the design axis and the pile body axis are located, and extend the hydraulic telescopic rod to push the deviation rectification wing plate out from the strip wing plate holes on the circular side plate; Continue to hammer the PHC pipe pile to make the pile body axis of the PHC pipe pile deviate towards the design axis; After the pile body axis coincides with the design axis, shorten the hydraulic telescopic rod to retract the deviation rectification wing plate into the circular side plate.

[0012] Step 7. Continue to hammer the PHC pipe pile through the pile hammer and carry out deviation rectification operations according to the method described in Step 6 until the PHC pipe pile is implanted to the designed depth.

[0013] Step 8. After the PHC pipe pile is implanted to the designed depth, control the lead screw motor to move upward along the central screw to make the support plate contract inward, release the temporary fixation of the deviation rectification control system and the PHC pipe pile, and pull out the deviation rectification control system from the PHC pipe pile as a whole through the towing rope.

[0014] Preferably, in the step 1, a plurality of triangular stiffening plates are evenly arranged between the annular wing plate and the circular side plate, and the triangular stiffening plates can improve the connection strength between the annular wing plate and the circular side plate.

[0015] Preferably, in the step 2, a limit block and a lifting ring are provided at the top of the central screw rod. The limit block prevents the screw rod motor from slipping off the top of the central screw rod. A towing rope is connected to the lifting ring, which is convenient for later overall towing of the deviation rectification control system out of the PHC pipe pile. The screw rod motor and the rotating motor are respectively connected to the first cable and the second cable, and the screw rod motor and the rotating motor are respectively controlled through the first cable and the second cable. The hydraulic telescopic rod is connected to the hydraulic oil pipe, and the telescopic of the hydraulic telescopic rod is controlled through the hydraulic oil pipe.

[0016] Preferably, in the step 1, the strip-shaped wing plate holes on the circular side plate are inclined. In the step 2, the inclination angle of the deviation rectification wing plate is the same as that of the strip-shaped wing plate hole. In the step 4, the deviation rectification wing plate is aligned with the strip-shaped wing plate hole, and the deviation rectification wing plate can extend out of the outer side of the precast deviation rectification pile head from the strip-shaped wing plate hole. When the axis of the PHC pipe pile deflects, the deviation rectification wing plate is extended from the precast deviation rectification pile head and inserted into the surrounding soil of the pile. The PHC pipe pile is hammered downwards, and under the guidance of the deviation rectification wing plate, the axis of the pile body is forced to deflect towards the design axis. After the axis of the pile body coincides with the design axis, the deviation rectification wing plate is retracted into the precast deviation rectification pile head.

[0017] Preferably, in the step 2, the screw rod motor can move up and down along the central screw rod, and multiple groups of movable support rods and support plates are arranged circumferentially along the central screw rod. By moving the screw rod motor downwards or upwards, the support plate is controlled to expand outwards or contract inwards, so as to temporarily fix the deviation rectification control system inside the PHC pipe pile or release the temporary fixation.

[0018] Preferably, in the step 2, a stiffening plate is arranged between the limit channel steel and the bearing plate. The stiffening plate can improve the connection strength between the limit channel steel and the bearing plate, and the limit channel steel can provide a stable and reliable limiting and guiding effect for the extension and retraction of the deviation rectification wing plate.

[0019] Preferably, in the step 3, the axis of the guiding sleeve is aligned with the design axis of the PHC pipe pile. A sand cushion layer is provided at the bottom of the guiding sleeve. The sand cushion layer can prevent concrete from entering the guiding sleeve when pouring the concrete retaining ring, increasing the difficulty of driving the PHC pipe pile in the later stage.

[0020] Preferably, in the step 5, a pile cap is arranged on the top of the PHC pipe pile. There is an L-shaped through hole on the pile cap. The towing rope, the first cable, the second cable and the hydraulic oil pipe pass through the L-shaped through hole on the pile cap at the top of the PHC pipe pile. The L-shaped through hole on the pile cap can prevent the towing rope, the first cable, the second cable and the hydraulic oil pipe from being broken by the pile hammer.

[0021] Adopting the technical solution provided by the present invention, compared with the prior art, it has the following beneficial effects:

[0022] 1. The deviation correction control system is built inside the PHC pipe pile and can be controlled on the ground through external cables, hydraulic hoses, etc. After the pile is in place, the deviation correction control system can be withdrawn from the pipe pile as a whole through the towing rope and used for the deviation correction construction of the next pile foundation.

[0023] 2. The prefabricated deviation correction pile head has a simple and reliable structure. Compared with the traditional steel structure prefabricated pile head, only two strip-shaped wing plate holes are opened on the side wall of the pile head and two groups of limiting plates are welded inside, and the manufacturing cost is low.

[0024] 3. The deviation correction control system integrates a biaxial dynamic inclination sensor to monitor the inclination of the pile body axis in real time. When the pile body axis deflects relative to the designed axis, the pile body can be immediately corrected to avoid increasing the difficulty of deviation correction due to excessive pile foundation deviation.

[0025] 4. There is an L-shaped through hole on the pile cap at the top of the pipe pile, and the towing rope, cable, hydraulic hose, etc. pass through the L-shaped through hole on the pile cap, thus avoiding the situation that the towing rope, cable, and hydraulic hose are broken by the pile hammer.

[0026] 5. The PHC inclined pile deviation correction pile tip and control system proposed by the present invention can significantly improve the driving accuracy of PHC inclined piles, reduce the difficulty of deviation correction operations, and improve the pile driving efficiency.
