Description

Technical Field

[0001] This utility model relates to the field of static pressure piling technology, specifically a static pressure piling deviation warning and correction device. Background Technology

[0002] Static pressure piling is a method of engineering pile foundation construction. It involves using a static pile driver, with the machine's own weight and counterweights on its frame providing the reaction force, to drive precast piles into the soil. Static pressure piling avoids the vibration, noise, and pollution caused by hammer piling, thus offering advantages such as no damage to the pile, no noise, no vibration, no impact, and no pollution during construction.

[0003] However, the lack of real-time monitoring of the pipe piles during the piling process means that measurements are taken after the pipe piles are driven into the ground. If the deviation exceeds the maximum allowable value, the piling process must be restarted, affecting the overall construction progress. Utility Model Content

[0004] The purpose of this invention is to provide a static pressure pile deviation early warning and correction device, which can monitor the posture of the pile body in real time during the pile driving process and avoid large deviations.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A static pressure pile deviation warning and correction device includes a correction mechanism receiving cylinder connected to the bottom of the pile driver and with its opening facing downward, and a correction warning mechanism connected to the correction mechanism receiving cylinder.

[0007] The correction and early warning mechanism includes a correction mechanism support column that is slidably connected inside the correction mechanism housing, a ranging support column located on the side of the correction mechanism support column, and a vertical attitude sensor located inside the correction mechanism support column. The ranging support column is equipped with multiple laser ranging sensors.

[0008] The correction mechanism support column is equipped with a distance measuring drive telescopic rod for driving the distance measuring support column to move radially along the correction mechanism support column.

[0009] The bottom of the support column of the correction mechanism is fixed with multiple sturdy ground nails.

[0010] Preferably, the correction mechanism housing is connected to the bottom of the pile driver via a lifting mechanism.

[0011] Preferably, the lifting mechanism includes a lifting mechanism fixed cylinder fixed to the bottom of the pile driver with the opening facing downwards, a lifting mechanism drive cylinder with the opening facing upwards slidably connected inside the lifting mechanism fixed cylinder, the lower end of the lifting mechanism drive cylinder being fixedly connected to the correction mechanism receiving cylinder, and a lifting drive telescopic rod for driving the lifting mechanism drive cylinder to move vertically inside the lifting mechanism fixed cylinder.

[0012] Note: The lifting mechanism facilitates the fixing of the correction mechanism support column on the ground and ensures that the posture of the correction mechanism support column remains stable in a vertical position.

[0013] Preferably, the upper end of the support column of the correction mechanism is connected to the top of the cavity inside the correction mechanism housing via a cable mechanism.

[0014] Preferably, the hoisting mechanism includes a winch fixed to the top of the housing cylinder of the correction mechanism, a lifting lug fixed to the upper end of the support column of the correction mechanism, and the cable of the winch fixedly connected to the lifting lug.

[0015] Note: The winch facilitates the retraction of the correction mechanism support column back into the correction mechanism housing.

[0016] Preferably, a storage limiting ring is fixed on the outside of the support column of the correction mechanism.

[0017] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0018] 1. The present invention has a reasonable structural design and uses multiple laser ranging sensors to monitor the relative position distance between the support column of the correction mechanism and the pipe pile in real time, thereby monitoring whether the posture of the pipe pile has deviated.

[0019] 2. This utility model has a vertical attitude sensor installed inside the support column of the correction mechanism, which can monitor the attitude change of the support column of the correction mechanism in real time, and then compensate and correct the monitoring data of the pipe pile.

[0020] 3. This utility model uses a lifting mechanism to easily fix the support column of the correction mechanism on the ground and ensure that the posture of the support column of the correction mechanism is stable in a vertical state, and uses a winch to easily store the support column of the correction mechanism back into the cavity of the correction mechanism.

[0026] Example:

[0027] A static pressure pile deviation early warning and correction device, such as Figure 1 As shown, it includes a correction mechanism housing 10 connected to the bottom of the pile driver and with its opening facing downwards, and a correction early warning mechanism 20 connected to the correction mechanism housing 10.

[0028] like Figure 1 As shown, the correction and early warning mechanism 20 includes a correction mechanism support column 21 that is slidably connected within the correction mechanism receiving cylinder 10, such as... Figure 3 As shown, the side of the correction mechanism support column 21 has a vertically extending correction receiving groove 211, and a vertically extending ranging support column 22 is provided in the correction receiving groove 211. The side of the ranging support column 22 has multiple ranging receiving holes 221, and a laser ranging sensor 220 is fixed in the ranging receiving hole 221.

[0029] The correction receiving groove 211 has a drive receiving hole 212 extending radially along the correction mechanism support column 21, and the drive receiving hole 212 is provided with a ranging drive telescopic rod 213 for driving the ranging support column 22 to move radially along the correction mechanism support column 21.

[0030] The distance measuring drive telescopic rod 213 is an electrically controlled telescopic rod. The outer end of the distance measuring drive telescopic rod 213 is fixedly connected to the inner end of the drive receiving hole 212, and the inner end of the distance measuring drive telescopic rod 213 is fixedly connected to the side of the distance measuring support column 22.

[0031] like Figure 2 As shown, the support column 21 of the correction mechanism has a vertically extending attitude sensor receiving hole 231, and a vertical attitude sensor 23 is fixed in the attitude sensor receiving hole 231.

[0032] The bottom of the correction mechanism support column 21 is fixed with multiple sturdy ground nails 210.

[0033] like Figure 1 As shown, the correction mechanism receiving cylinder 10 is connected to the bottom of the pile driver through the lifting mechanism 11. The lifting mechanism 11 includes a lifting mechanism fixed cylinder 111 fixed to the bottom of the pile driver with the opening facing downward. A lifting mechanism drive cylinder 112 with the opening facing upward is slidably connected inside the lifting mechanism fixed cylinder 111. The lower end of the lifting mechanism drive cylinder 112 is fixedly connected to the correction mechanism receiving cylinder 10. A lifting drive telescopic rod 113 for driving the lifting mechanism drive cylinder 112 to move in the vertical direction is provided inside the lifting mechanism fixed cylinder 111.

[0034] The lifting drive telescopic rod 113 is an electrically controlled telescopic rod. The outer rod end of the lifting drive telescopic rod 113 is fixedly connected to the top of the inner cavity of the lifting mechanism fixed cylinder 111, and the inner rod end of the lifting drive telescopic rod 113 is fixedly connected to the bottom of the inner cavity of the lifting mechanism drive cylinder 112.

[0035] like Figure 1 As shown, the upper end of the correction mechanism support column 21 is connected to the top of the correction mechanism receiving cylinder 10 through the cable mechanism 12. The cable mechanism 12 includes a winch 121 fixed to the top of the correction mechanism receiving cylinder 10. The upper end of the correction mechanism support column 21 is fixed with a lifting lug 122, and the cable of the winch 121 is fixedly connected to the lifting lug 122.

[0036] The outer side of the support column 21 of the correction mechanism is fixed with a storage limiting ring 123.

[0037] In practical application, after the static pressure machine presses one-tenth of the pipe pile into the ground, the early warning and correction device of this utility model is fixed on the ground surface around the pipe pile to monitor the posture of the pipe pile in real time.

[0038] The inner rod of the lifting drive telescopic rod 113 extends, driving the lifting mechanism drive cylinder 112 and the correction mechanism receiving cylinder 10 to move down together. The correction mechanism receiving cylinder 10 moves down together with the correction mechanism support column 21 inside it, inserting multiple stable ground nails 210 into the ground, thereby fixing the correction mechanism support column 21 to the ground surface. Then the inner rod of the lifting drive telescopic rod 113 retracts, driving the lifting mechanism drive cylinder 112 and the correction mechanism receiving cylinder 10 to move up and return to the original position. During this process, the cable of the winch 121 is released to adapt to the change in the relative distance between the correction mechanism support column 21 and the correction mechanism receiving cylinder 10.

[0039] The inner rod of the ranging drive telescopic rod 213 extends, causing the ranging support column 22 to extend radially along the correction mechanism support column 21, so that the ranging support column 22 extends out of the correction receiving groove 211. Then, multiple laser ranging sensors 220 are used to monitor the relative position distance between the correction mechanism support column 21 and the pipe pile in real time, thereby monitoring whether the posture of the pipe pile has deviated. In addition, the vertical posture sensor 23 inside the correction mechanism support column 21 can monitor the posture change of the correction mechanism support column 21 itself in real time, thereby compensating and correcting the monitoring data of the pipe pile.

[0040] After the work is completed, the inner rod of the ranging drive telescopic rod 213 retracts, causing the ranging support column 22 to retract into the correction receiving groove 211. Then the cable of the winch 121 is tightened, and the winch 121 drives the correction mechanism support column 21 to move upward, so that the correction mechanism support column 21 returns to the correction mechanism receiving cylinder 10.
