DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0031] The present invention provides an engineering pile sinking construction process, comprising the following steps:

[0032] S1. Re-survey the control points and leveling points, and on this basis, use the total station to guide the survey and establish the construction survey control coordinate system of this project;

[0033] S2. Confirm the pile sinking position, lift and transport the pile by crane, and transport the pile to the pile sinking position so that it remains in a vertical state;

[0034] S3. Connect the top of the pile to the piling equipment, and then drive the pile into the soil at the pile sinking position through the piling equipment to complete the pile sinking.

[0035] like Figures 1 to 8As shown, the piling equipment includes a frame 1, a hammer head 2 is arranged on the outside of the frame 1, a pile cap 3 is arranged at the bottom of the frame 1, an oil nozzle 4 is arranged on the top of the pile cap 3, a rocker 6 is arranged on the front side of the pile cap 3, a pressing pin 5 for squeezing the rocker 6 is arranged on the front side of the hammer head 2, the pressing pin 5, the rocker 6, and the oil nozzle 4 are corresponding components on a diesel pile driver in the prior art, the pressing pin 5 squeezes the rocker 6 to make the oil nozzle 4 spray oil, a control rod 7 for controlling the position of the rocker 6 is arranged on the front side of the rocker 6, the control rod 7 is a control rod for controlling the position of the rocker arranged on the pile cap in the prior art, and the position of the rocker can be adjusted by pulling down one end of the control rod, so that the rocker and the pressing pin cannot contact each other, Thereby, the oil injection of the injector is stopped, the pile cap loses power and finally stops. A mounting disk 8 is fixedly installed at one end of the control rod 7, and a winding disk 9 is rotatably installed on the front side of the mounting disk 8. The outer sleeve of the winding disk 9 is provided with a first torsion spring 10, and the two ends of the first torsion spring 10 are respectively fixedly connected to the mounting disk 8 and the winding disk 9. The outside of the winding disk 9 is provided with a limiting component for limiting its rotation direction. The inside of the winding disk 9 is fixedly connected with a pull rope 11, which is wound in the winding disk 9, and a counterweight block 12 is fixedly installed on the bottom end of the pull rope 11. A supporting component for supporting the control rod 7 is provided on the outside, and a fixing component for fixing the control rod 7 is provided on the front side of the pile cap 3.

[0036] When in use, the frame 1 is installed on the guide rail for installing it, and the restriction of the limiting component on the winding drum 9 is cancelled. Under the action of gravity, the counterweight block 12 descends and cooperates with the pull rope 11 to pull the winding drum 9 to rotate forward, so that the first torsion spring 10 is twisted to cause its torsional deformation to generate a force, and finally the counterweight block 12 falls to the ground, and then the restriction of the limiting component on the winding drum 9 is restored. A lifting assembly for lifting the hammer head 2 is provided on the frame 1. The lifting assembly is a lifting assembly for lifting the hammer head set on the diesel pile driver in the prior art. After the top of the pile is connected to the pile cap 3, the hammer head 2 is lifted by the lifting assembly and then put down. The hammer head 2 is under the gravity. The rapid descent under the action causes the pressing pin 5 to squeeze the rocker 6, so that the oil nozzle 4 is controlled to spray oil. At this time, the air compression between the cavity at the bottom of the hammer head 2 and the oil nozzle 4 generates high temperature to ignite the sprayed oil, causing an explosion. The impact force generated pushes the pile cap 3 downward and the hammer head 2 upward. After the hammer head 2 leaves, the pressing pin 5 also leaves. At this time, the squeezing of the rocker 6 and the oil spraying are cancelled. Subsequently, under the action of gravity, the hammer head 2 continues to move, repeatedly impacting the pile cap 3 to make it descend with the pile, thereby realizing pile sinking. In the process of the continuous descent of the pile cap 3, the pull rope 11 is continuously loosened, and the first torsion spring 10 is released at this time. The force causes the winding drum 9 to reverse, so that the pull rope 11 is wound up and put into a tensioned state. When it is necessary to stop pile sinking, the pull rope 11 can be pulled to make it rotate forward with the winding drum 9, but it is restricted by the restriction component, so that the winding drum 9 cannot rotate forward. Therefore, under the pulling of the pull rope 11, the winding drum 9, the mounting plate 8, and the control rod 7 are rotated to contact with the fixing component, so that the control rod 7 is fixed, so that the control rod 7 manipulates the position of the rocker 6 so that it cannot contact the pressing pin 5, resulting in the subsequent inability to spray oil and provide impact force for the pile cap 3, so that the pile sinking is stopped. In order to control the control rod 7 in time, the pile is stopped. When the pile driving device is used, the pull rope 11 is adjusted in real time during the whole pile sinking process to make it in a taut state. Therefore, when it is necessary to stop the pile sinking, the pull rope 11 is pulled to immediately realize the rotation of the control rod 7, so that the pile sinking can be stopped immediately. In addition, there is no need to manually pull and tighten the pull rope 11 during the whole process, thus saving manpower.

[0037] like Figures 1 to 5 As shown, the limiting component includes a ratchet 28 fixedly mounted on the inner side of the winding disk 9, a rotating shaft 14 is rotatably mounted on the front side of the mounting disk 8, a pawl 13 cooperating with the ratchet 28 is fixedly mounted on the front end of the rotating shaft 14, a second torsion spring 15 is sleeved on the outside of the rotating shaft 14, and both ends of the second torsion spring 15 are respectively fixedly connected to the mounting disk 8 and the pawl 13, and a control component for controlling the pawl 13 to rotate upward is provided on the front side of the mounting disk 8.

[0038] When the ratchet 28 is combined with the pawl 13, the winding disk 9 cannot rotate forward at this time. The pawl 13 is controlled by the control component to rotate it upward, and the second torsion spring 15 causes it to torsionally deform and generate a force, so that the pawl 13 is separated from the ratchet 28. At this time, the winding disk 9 can rotate forward. Otherwise, the control of the control component is cancelled, and the second torsion spring 15 releases the force and causes the pawl 13 to rotate downward and reset, so that it meshes with the ratchet 28, and the winding disk 9 cannot rotate forward.

[0039] like Figure 5 As shown, the control component includes a first electromagnet 16 fixedly connected to the front side of the mounting plate 8 through a connecting rod. The first electromagnet 16 is located above the pawl 13. The pawl 13 is made of iron. A remote controller 17 and a battery 18 are provided on the front side of the mounting plate 8. The battery 18 supplies power to the remote controller 17 and the first electromagnet 16. The remote controller 17 can control the first electromagnet 16 to power it on and off.

[0040] The first electromagnet 16 is energized by the remote controller 17 to make it magnetic, so that the pawl 13 is attracted to rotate upward, thereby twisting the second torsion spring 15 to deform it and generate a force. Conversely, the first electromagnet 16 is deenergized to lose its magnetism, and the pawl 13 is rotated downward and reset under the action of the second torsion spring 15.

[0041] like Figure 3 and Figure 5 As shown, the support assembly includes a connecting plate 19 fixedly installed on the front side of the pile cap 3, and an arc rod 20 is fixedly installed on one side of the connecting plate 19. The center of the arc rod 20 is consistent with the central fulcrum position of the rotation of the control rod 7. A spring 21 is sleeved on the outside of the arc rod 20, and the two ends of the spring 21 are fixedly connected to the control rod 7 and the connecting plate 19 respectively. The control rod 7 is slidably sleeved outside the arc rod 20.

[0042] When the control rod 7 rotates, the spring 21 is compressed to deform and generate a force. After the pull rope 11 is loosened, the spring 21 releases the force and rotates and resets the control rod 7.

[0043] like Figure 3 and Figure 5 As shown, the elastic force of the spring 21 is greater than the gravity exerted on the counterweight 12 , the pull rope 11 , the winding drum 9 , the mounting disk 8 , all components mounted thereon, and the control rod 7 .

[0044] The spring 21 can support the control rod 7 to keep it stationary.

[0045] like Figure 3 , Figure 5 and Figure 7As shown, the fixing assembly includes a first cylinder 22 and a second cylinder 23 symmetrically fixedly mounted on the front side of the pile cap 3, the first cylinder 22 and the second cylinder 23 are located below the control rod 7, a protective cover 25 is sleeved on the outside of the second cylinder 23, a notch is provided at the bottom of the protective cover 25, one end of the protective cover 25 is rotatably connected to the front side of the pile cap 3, a rotating assembly for driving the rotation of the protective cover 25 is provided on the outside, the second cylinder 23 is made of iron, a second electromagnet 24 corresponding to the position of the second cylinder 23 is fixedly mounted on the bottom of the control rod 7, the battery 18 supplies power to the second electromagnet 24, and the remote controller 17 can control the second electromagnet 24 to power it on and off.

[0046] When the control rod 7 needs to be fixed, the second electromagnet 24 is controlled by the remote controller 17 so that it is energized and has magnetism. At this time, as the control rod 7 rotates, the control rod 7 cooperates with the rotating assembly to drive the protective cover 25 to rotate, so that the notch of the protective cover 25 rotates obliquely upward, and the surface of the second cylinder 23 is exposed. At this time, the second electromagnet 24 under the control rod 7 is adsorbed and fixed to the exposed part of the second cylinder 23 to achieve the fixation of the control rod 7. The surface of the second cylinder 23 can be shielded by the protective cover 25 to prevent particles generated by the explosion from falling on the contact area between the second cylinder 23 and the second electromagnet 24, so as to prevent particles from affecting the adsorption and fixation between the second cylinder 23 and the second electromagnet 24. When the control rod 7 is rotated and reset, the rotating assembly drives the protective cover 25 to rotate and reset, so that the notch faces downward, so that the protective cover 25 can shield the second cylinder 23 from dust.

[0047] like Figure 3 , Figure 5 and Figure 7 As shown, the rotating assembly includes teeth 26 equidistantly arranged around the outside of the protective cover 25, and a rack 27 meshing with the teeth 26 is fixedly installed at the bottom of the control rod 7. The rack 27 is an arc-shaped rack, and the center of the rack 27 is consistent with the central fulcrum position of the rotation of the control rod 7.

[0048] The control rod 7 rotates with the rack 27 , and the matching teeth 26 rotate with the protective cover 25 .

[0049] Working principle: When in use, the frame 1 is installed on the guide rail for installing it. When the ratchet 28 is combined with the pawl 13, the winding disk 9 cannot rotate forward at this time. The first electromagnet 16 is controlled by the remote controller 17 to be energized to make it magnetic, so that the pawl 13 is attracted to rotate upward, thereby twisting the second torsion spring 15 to deform it and generate a force. As the pawl 13 moves, it separates from the ratchet 28. At this time, the winding disk 9 can rotate forward. Under the action of gravity, the counterweight block 12 descends and cooperates with the pull rope 11 to pull the winding disk 9 forward, so that the first torsion spring 10 is twisted to torsion deformation to generate a force, and finally the counterweight block 12 falls to the ground, and then the first electromagnet 16 is controlled to be powered off to make it lose its magnetism, and under the action of the second torsion spring 15, the pawl 13 rotates downward to reset. Engaged with the ratchet 28, the winding disk 9 cannot rotate forward. A lifting assembly for lifting the hammer head 2 is provided on the frame 1. The lifting assembly is a lifting assembly for lifting the hammer head set on the diesel pile driver in the prior art. After the top of the pile is connected to the pile cap 3, the hammer head 2 is lifted by the lifting assembly and then put down. The hammer head 2 drops rapidly under the action of gravity so that the rocker 6 is squeezed with the pressing pin 5, so that the fuel injector 4 is controlled to spray oil. At this time, the air compression between the cavity at the bottom of the hammer head 2 and the fuel injector 4 generates high temperature to ignite the sprayed oil, so that an explosion occurs. The impact force generated pushes the pile cap 3 downward and the hammer head 2 upward. After the hammer head 2 leaves, the pressing pin 5 leaves with it. At this time, the squeezing of the rocker 6 is cancelled, and the fuel injection is cancelled. Then, under the action of gravity, the hammer head 2 continues to move. The pile cap 3 is moved, and the pile cap 3 is impacted repeatedly to make it descend with the pile, so as to realize pile sinking. In the process of continuous descent of the pile cap 3, the pull rope 11 is continuously loosened. At this time, the first torsion spring 10 releases the force to reverse the winding drum 9, so that the pull rope 11 is wound up and put into a tensioned state. When it is necessary to stop the pile sinking, the pull rope 11 can be pulled to make it rotate forward with the winding drum 9. Due to the engagement of the ratchet 28 and the pawl 13, the winding drum 9 cannot rotate forward. Therefore, under the pulling of the pull rope 11, the winding drum 9, the mounting plate 8 and the control rod 7 are rotated. The second electromagnet 24 is controlled in advance by the remote controller 17 to be energized and magnetic. At this time, as the control rod 7 rotates, the second electromagnet 24 is adsorbed and fixed to the second cylinder 23, completing the control of the control rod 7. The fixing of the control rod 7 makes it impossible for the control rod 7 to manipulate the position of the rocker 6 to make it unable to contact the pressing pin 5, resulting in the subsequent inability to spray oil, unable to provide impact force for the pile cap 3, and stopping pile sinking. In order to be able to control the control rod 7 in time and stop pile sinking, during actual work, it is necessary for the staff to tighten the pull rope 11 that becomes loose due to the descent of the pile cap 3 and swings around due to the vibration during pile sinking at all times on site, so that when the control rod 7 needs to be controlled, the control rod 7 can be immediately pulled in conjunction with the pull rope 11 to achieve control. When the present piling equipment is used, the pull rope 11 is adjusted in real time during the entire pile sinking process to keep it in a taut state. Therefore, when it is necessary to stop pile sinking, pulling the pull rope 11 can immediately realize the rotation of the control rod 7, so that pile sinking can be stopped immediately.And in the whole process, there is no need to manually pull and tighten the pull rope 11, which saves manpower; the control rod 7 rotates with the rack 27, and the teeth 26 rotate with the protective cover 25, so that the gap of the protective cover 25 rotates obliquely upward, and the surface of the second cylinder 23 is leaked. At this time, the second electromagnet 24 under the control rod 7 is adsorbed and fixed with the exposed part of the second cylinder 23 to achieve the fixation of the control rod 7. The surface of the second cylinder 23 can be shielded by the protective cover 25 to prevent the particles produced by the explosion from falling on the contact part between the second cylinder 23 and the second electromagnet 24, and to prevent the particles from affecting the adsorption and fixation between the second cylinder 23 and the second electromagnet 24. When the control rod 7 rotates, it will compress the spring 21 to deform it and generate a force. After loosening the pull rope 11, the second electromagnet 24 can be powered off, and the spring 21 releases the force to rotate and reset the control rod 7. Conversely, the protective cover 25 can be reset, so that the gap is facing downward, and the protective cover 25 can block and dustproof the second cylinder 23.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
