Description
Technical Field
[0001] The invention belongs to the technical field of pipe pile construction, and in particular relates to a pipe pile hole-guiding construction device and a hole-guiding method. Background Art
[0002] In the field of construction engineering, prestressed concrete pipe piles are widely used in various construction projects due to their high bearing capacity, fast construction speed and relatively low cost. There are many methods for the construction of pipe piles, among which the hole construction is an important technical means, which can effectively solve the problem that pipe piles are difficult to enter the ground under complex geological conditions.
[0003] At present, conventional pipe pile boring construction often uses a rotary drill to conduct boring operations, and then uses a static press to implant the pipe piles into the boring operations. However, this construction method has many disadvantages. On the one hand, conventional rotary drills cannot work synchronously with static presses. After the rotary drill completes the boring operation, the equipment needs to be evacuated from the construction site, and then the static press needs to be moved to the boring location to implant the pipe piles. This process not only increases the construction time cost and reduces the construction efficiency, but also requires more manpower and material resources to coordinate the workflow of the two equipment.
[0004] On the other hand, the method of drilling holes by taking soil out of the hole also has obvious defects. In the process of taking soil out of the hole, it is easy to disturb the soil around the hole wall, resulting in a decrease in the stability of the hole wall. Especially when drilling holes in soft soil layers with loose soil, it is very easy to cause hole collapse, which seriously affects the construction quality and progress. Summary of the invention
[0005] The embodiment of the present invention provides a pipe pile hole construction device and a hole construction method thereof, aiming to improve the construction efficiency of the pipe pile hole construction and the stability of the hole wall.
[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: in the first aspect, a pipe pile boring construction device is provided, including a tower, a pushing assembly, a heavy hammer assembly and a controller; the tower is used to fix the pipe pile; the pushing assembly is arranged on the tower and is located directly above the pipe pile, and the output end of the pushing assembly is provided with a push cylinder, which is used to push the pipe pile downward; the heavy hammer assembly is arranged on the tower, and the output end of the heavy hammer assembly has a hammer body suitable for penetrating the push cylinder, and the hammer body is used to enter the pipe pile under the guidance of the push cylinder and reciprocate up and down in the pipe pile; the controller is arranged on one side of the tower, and the controller is electrically connected to the pushing assembly and the heavy hammer assembly.

[0008] In some embodiments, at least one sliding hole is opened at the bottom of the hammer body, the sliding hole is located at one side of the soil taking bin, and the door blocking structure is slidably arranged in the sliding hole.
[0009] Exemplarily, the door-blocking structure includes a first telescopic driving member, a first plate body and a second plate body; the first telescopic driving member is arranged inside the sliding hole and is electrically connected to the controller; the first plate body is slidably arranged in the sliding hole and is connected to the output end of the first telescopic driving member, and a rotating driving member is provided on the first plate body, and the rotating driving member is electrically connected to the controller; the second plate body is slidably connected to the sliding hole, and is rotationally connected to the first plate body, and is connected to the output end of the rotating driving member.
[0010] For example, a position sensor is provided on the tower, which is located directly above the hammer and electrically connected to the controller. The position sensor is used to detect the position information of the hammer and feed back the detection data to the controller; a pressure sensor is provided on the hammer, which is electrically connected to the controller. The pressure sensor is used to detect the pressure that the hammer is subjected to when hammering the soil, and feed back the detection data to the controller.
[0011] In combination with the first aspect, in a possible implementation, the pushing assembly includes a second telescopic driving member and a push cylinder, the second telescopic driving member is arranged on the tower and is electrically connected to the controller, and the output end of the second telescopic driving member is connected to the push cylinder.
[0012] In some embodiments, the heavy hammer assembly includes a winch, a traction rope, a roller group and a hammer body; the winch is arranged on one side of the tower and is electrically connected to the controller, the roller group is arranged on the top of the tower and is located directly above the push cylinder; one end of the traction rope is wound around the output end of the winch, and the other end is wrapped around the roller group to connect to the hammer body.
[0013] The beneficial effect of the pipe pile hole construction device provided by the present invention is that: compared with the prior art, the pipe pile hole construction device of the present invention uses a heavy hammer to free-fall and hammer inside the pipe pile, and a push tube to synchronously push the pipe pile down, and can be applied to the construction of hard soil hole construction by utilizing the dual effects of hammering and static pressure, greatly shortening the construction time and improving the overall construction efficiency. The hammer body performs reciprocating free-fall motion inside the pipe pile, and squeezes the soil body when hammering, causing the soil body to spread to the surroundings, increasing the soil density of the hole wall, reducing the disturbance of the soil body around the hole wall, reducing the risk of hole collapse, and ensuring the construction quality.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0021] Please also read Figures 1 to 5 , the construction device for boring a pipe pile 60 provided by the present invention is now described. The construction device for boring a pipe pile 60 comprises a tower 10, a jacking assembly 20, a weight assembly 30 and a controller 40; the tower 10 is used to fix the pipe pile 60; the jacking assembly 20 is arranged on the tower 10 and is located directly above the pipe pile 60, and a push cylinder 21 is arranged at the output end of the jacking assembly 20, and the push cylinder 21 is used to push the pipe pile 60 downward; the weight assembly 30 is arranged on the tower 10, and a hammer body 31 is provided at the output end of the weight assembly 30 for penetrating the push cylinder 21, and the hammer body 31 is used to enter the pipe pile 60 under the guidance of the push cylinder 21 and reciprocate up and down in the pipe pile 60; the controller 40 is arranged on one side of the tower 10, and the controller 40 is electrically connected to the jacking assembly 20 and the weight assembly 30.
[0022] It should be noted that the tower 10 is arranged on the static press, which is the foundation of the entire device and can provide a support position for the installation and operation of the device. The jacking assembly 20 is arranged on the tower 10 and is located above the pipe pile 60. On the one hand, the jacking assembly 20 is used to push the upper surface of the pipe pile 60 to provide power for the downward pressure of the pipe pile 60; on the other hand, it has a guide channel aligned with the inner wall of the pipe pile 60, which plays a guiding role for the hammer 31, ensures the movement trajectory of the hammer 31 in the pipe pile 60, and can also protect and position the upper mouth of the pipe pile 60. The heavy hammer assembly 30 is installed on the static press, and the core component is the hammer 31. The hammer 31 performs free fall motion in the guide channel to realize the hammering of the soil under the pipe pile 60. The controller 40 is electrically connected to the jacking assembly 20 and the heavy hammer assembly 30 to realize the automatic control and coordination of the entire construction device. During the hole construction process, when the hammer 31 reciprocates and freely falls to hammer the soil, the pipe pile 60 can be pressed down synchronously.
[0023] In the construction of soft soil layers, the hammer 31 can use the hammering effect to improve the density of the soil around the pipe pile 60, improve the bearing capacity of the soil, reduce the risk of soil collapse, and thus improve the stability of the pipe pile 60. In the construction of hard soil layers, the soil density is high and the pipe pile 60 is not easy to sink. The dual effects of the hammer 31 and the static pressure of the push cylinder 21 are used to hammer and crush the soil, and the static pressure pipe pile 60 sinks, which can meet the drilling operation needs of the hard soil layer and improve the drilling construction efficiency.
[0024] Compared with the prior art, the construction device for boring a hole for a pipe pile 60 provided by the present invention uses a heavy hammer to free-fall inside the pipe pile 60, and the push tube 21 synchronously pushes the pipe pile 60 downward, and can be applied to boring construction in hard soil by utilizing the dual effects of hammering and static pressure, greatly shortening the construction time and improving the overall construction efficiency. The hammer body 31 performs reciprocating free-fall motion inside the pipe pile 60, and squeezes the soil body when hammering it, causing the soil body to spread to the surroundings, increasing the soil density of the hole wall, reducing the disturbance of the soil body around the hole wall, reducing the risk of hole collapse, and ensuring the construction quality. By electrically connecting the controller 40 with each part, precise control of the pushing assembly 20 and the heavy hammer assembly 30 can be achieved, so that the device can adapt to the boring construction of pipe piles 60 under different geological conditions.
[0025] In one possible implementation, see Figure 2 The bottom of the hammer body 31 has a soil bin 311; a door blocking structure 50 is provided at the opening of the soil bin 311, and the door blocking structure 50 is closed when the hammer body 31 moves upward and opened when the hammer body 31 moves downward. The door blocking structure 50 is electrically connected to the controller 40.
[0026] It should be noted that when encountering a hard soil layer, the construction method of relying solely on the hammer 31 to squeeze the soil down is not effective. The hard soil layer has a large anti-extrusion force, and the soil changes little when the hammer 31 hits the hard soil layer. The soil taking bin 311 can take soil when hammering the hard soil layer, effectively reducing the resistance of the soil to the implantation of the pipe pile 60, so that the device can adapt to more complex geological conditions and broaden the scope of application of the device. During the rising process of the hammer 31, the soil in the soil taking bin 311 is prone to fall, and the soil needs to be taken again when it falls and hammers again, resulting in a decrease in the efficiency of the soil taking operation. The gate structure 50 can effectively prevent the soil in the soil taking bin 311 from falling, so that after each hammering to take soil, the controller 40 controls the gate structure 50 to close the soil taking bin 311, so that the soil in the soil taking bin 311 can be retained, reducing unnecessary repeated soil taking operations and saving construction time. The setting of the gate structure 50 can ensure the continuity of the soil taking operation, avoid the situation where the soil taking operation needs to be frequently adjusted due to soil falling, and improve the overall construction efficiency. The soil falling during the rising process of the hammer body 31 will impact and disturb the hole wall, affecting the stability of the hole wall. When constructing in a soft soil layer, the door structure 50 closes the soil bin 311 to close the soil taking function of the soil bin 311. The hammering of the soft soil layer by the heavy hammer can squeeze the soil and spread it around to increase the soil density and enhance the bearing capacity of the soil.
[0027] For some examples, see Figure 2 At least one sliding hole 312 is formed at the bottom of the hammer body 31 . The sliding hole 312 is located at one side of the soil taking bin 311 . The door blocking structure 50 is slidably disposed in the sliding hole 312 .
[0028] It should be noted that the existence of the sliding hole 312 provides a clear movement path for the door structure 50, so that the door structure 50 can slide at the bottom of the hammer body 31 in a preset manner. When the controller 40 controls the opening of the soil bin 311 to open or close, the door structure 50 can move precisely along the sliding hole 312, thereby achieving effective control of the soil bin 311. There can be two sliding holes 312, and each sliding hole 312 is provided with a door structure 50 inside. The two door structures 50 cooperate with each other to close the soil bin 311, and after closing the soil bin 311, the bottom surface of the hammer body 31 is leveled, so as to avoid the tilt of the hammer hole generated when hammering the ground, and improve the accuracy of the hole leading of the pipe pile 60.
[0029] For example, see Figure 2 and Figure 3The door blocking structure 50 includes a first telescopic driving member 51, a first plate body 52 and a second plate body 54; the first telescopic driving member 51 is arranged inside the sliding hole 312 and is electrically connected to the controller 40; the first plate body 52 is slidably arranged in the sliding hole 312 and is connected to the output end of the first telescopic driving member 51, and a rotating driving member 53 is provided on the first plate body 52, and the rotating driving member 53 is electrically connected to the controller 40; the second plate body 54 is slidably connected to the sliding hole 312, and is rotationally connected to the first plate body 52, and is connected to the output end of the rotating driving member 53.
[0030] It should be noted that the first telescopic driving member 51 can be a cylinder, which can receive the electrical signal of the controller 40 and drive the first plate 52 to slide in the sliding hole 312 through a telescopic action. The position of the first plate 52 can be controlled, thereby driving the second plate 54 connected to the first plate 52 to move, so as to realize the opening and closing of the soil bin 311. The first plate 52, as an intermediate component connecting the first telescopic driving member 51 and the second plate 54, slides in the sliding hole 312 under the action of the first telescopic driving member 51. The rotating driving member 53 is installed on the first plate 52, which can receive the electrical signal of the controller 40 and drive the second plate 54 to rotate around the rotation connection point with the first plate 52 through a rotating action. The second plate 54 is slidably connected to the sliding hole 312, and the closing and opening of the soil bin 311 are realized under the joint action of the first plate 52 and the rotating driving member 53. The sliding connection between the first plate 52 and the second plate 54 and the sliding hole 312, as well as the rotational connection between the first plate 52 and the second plate 54, can ensure the stability and reliability of the door blocking structure 50 during movement. When the soil bin 311 is opened, the second plate 54 rotates around the first plate 52 and follows the first plate 52 to enter the sliding hole 312, so as to prevent the second plate 54 from affecting the flatness of the bottom of the hammer 31 when the hammer 31 falls, thereby improving the quality of the pipe pile 60. When the soil bin 311 is closed, the second plate 54 extends out of the sliding hole 312 driven by the first plate 52 and rotates under the drive of the rotating drive member 53 to close the soil bin 311, and the second plate 54 remains vertical with the first plate 52 after rotation, so that the bottom of the hammer 31 can form a horizontal bottom surface, which is conducive to ensuring the direction of the hole when the pipe pile 60 is bored and avoiding tilting. By accurately controlling the first plate body 52 and the second plate body 54 respectively by the first telescopic driving member 51 and the rotating driving member 53, the opening of the soil taking bin 311 can be accurately opened and closed, making the soil taking process more controllable. The amount of soil taken and the method of soil taking can be accurately controlled according to different soil layer conditions and construction requirements, thereby improving the accuracy and quality of construction.
[0031] For an example, see Figure 2 and Figure 4A position sensor 11 is provided on the tower 10. The position sensor 11 is located directly above the hammer body 31 and is electrically connected to the controller 40. The position sensor 11 is used to detect the position information of the hammer body 31 and feed back the detection data to the controller 40; a pressure sensor 313 is provided on the hammer body 31. The pressure sensor 313 is electrically connected to the controller 40. The pressure sensor 313 is used to detect the pressure that the hammer body 31 is subjected to when hammering the soil, and feed back the detection data to the controller 40.
[0032] It should be noted that the position sensor 11 can monitor the position information of the hammer 31 in the vertical direction of the tower 10 in real time, and transmit the position data of the hammer 31 to the controller 40, providing a basis for the controller 40 to accurately control the heavy hammer assembly 30. When the hammer 31 rises to a certain height, the position sensor 11 feedbacks a signal, and the controller 40 can control the winch 32 to stop lifting to avoid excessive rise of the hammer 31 and cause safety accidents; during the falling process of the hammer 31, through the position information feedback from the position sensor 11, the controller 40 can accurately grasp the falling stroke of the hammer 31 and provide basic data for adjusting the hammer force and frequency. The pressure sensor 313 can measure the pressure that the hammer 31 is subjected to during the process of hammering the soil. When the hammer 31 contacts the soil and applies force, the pressure sensor 313 senses the pressure change and transmits the pressure data to the controller 40. It helps the controller 40 to understand the hardness of the soil layer. Soil layers of different hardness have different reaction forces on the hammer 31. Through the pressure value fed back by the pressure sensor 313, the controller 40 can judge the characteristics of the soil layer and choose to control the baffle structure 50 to open the soil bin 311 to take soil when constructing a hard soil layer, thereby reducing the resistance of the soil to the implantation of the pipe pile 60 and improving the construction efficiency of the pipe pile 60.
[0033] In one embodiment, the pressure sensor 313 can be arranged inside the hammer body 31 near the bottom, which can protect the sensor from direct impact and damage from the external environment to a certain extent. During the hammering process, the surface of the hammer body 31 will be subjected to friction, collision and other effects of the soil. Placing the pressure sensor 313 inside can reduce the direct impact of external forces on the pressure sensor 313, and improve the service life and measurement stability of the pressure sensor 313. The pressure sensor 313 arranged inside the hammer body 31 and near the bottom can sense the comprehensive pressure transmitted to the inside by the hammer body 31 during the hammering process, including the pressure changes caused by factors such as the weight of the hammer body 31 itself, the hammering energy and the reaction force of the soil. By measuring and analyzing these comprehensive pressures, the interaction between the hammer body 31 and the soil can be more comprehensively understood, providing more abundant data for accurately calculating the soil resistance and evaluating the construction effect.
[0034] In one possible implementation, see Figure 4The pushing assembly 20 includes a second telescopic driving member 22 and a pushing cylinder 21 . The second telescopic driving member 22 is disposed on the tower 10 and is electrically connected to the controller 40 . The output end of the second telescopic driving member 22 is connected to the pushing cylinder 21 .
[0035] It should be noted that, by being electrically connected to the controller 40, the second telescopic drive member 22 can accurately move according to the instructions issued by the controller 40, so as to realize precise control of the pushing force and displacement of the push tube 21. It can ensure that the pipe pile 60 maintains a stable speed and pressure during the pressing process, avoids the pipe pile 60 from tilting or being damaged due to uneven pushing force, and improves the construction quality of the pipe pile 60 implantation. The second telescopic drive member 22 can be a jack, and the second telescopic drive member 22 can quickly respond to the instructions of the controller 40 to realize the rapid lifting and lowering of the push tube 21. During the construction of the pipe pile 60, the push tube 21 can rise quickly to install the pipe pile 60, and can quickly descend and push the pipe pile 60, greatly shortening the operation time of each pressing of the pipe pile 60, making the entire construction process more compact and efficient, and speeding up the construction progress. The second telescopic drive member 22 enables the working parameters of the push assembly 20 to be flexibly adjusted according to different construction requirements and geological conditions. For pipe piles 60 of different specifications or soil layers of different hardness, the output parameters of the second telescopic driving member 22 can be changed through the controller 40, thereby adjusting the pushing force and speed of the push cylinder 21 to enhance the adaptability to various construction scenes.
[0036] For some examples, see Figure 5 The heavy hammer assembly 30 includes a winch 32, a traction rope 33, a roller group 34 and a hammer body 31; the winch 32 is arranged on one side of the tower 10 and is electrically connected to the controller 40, the roller group 34 is arranged on the top of the tower 10 and is located directly above the push cylinder 21; one end of the traction rope 33 is wound around the output end of the winch 32, and the other end passes around the roller group 34 to connect to the hammer body 31.
[0037] It should be noted that the traction rope 33 can be a steel wire rope, and the winch 32 is connected to the hammer 31 through the traction rope 33, which can realize the lifting function of the hammer 31. When encountering different soil layers and needing to adjust the drop distance, the controller 40 can accurately control the lifting height of the hammer 31 to ensure that the hammering energy meets the construction requirements. The controller 40 can accurately control the rotation of the winch 32 according to the preset construction parameters and real-time monitoring data, and realize the automatic control of the rising and falling process of the hammer 31, which can not only improve the construction efficiency, but also reduce the errors and instability caused by manual operation. The roller group 34 is arranged on the tower 10 and rolls with the traction rope 33. The setting of the roller group 34 converts the sliding friction between the traction rope 33 and the tower 10 during the movement into rolling friction, greatly reducing the friction resistance. It helps to reduce energy loss and improve the operating efficiency of the equipment. At the same time, it can reduce the wear of the traction rope 33 and the tower 10 and extend the service life of the equipment. The roller group 34 can also guide and support the traction rope 33, ensuring that the traction rope 33 maintains a stable direction during movement, so that the hammer body 31 can accurately rise and fall along a predetermined trajectory, thereby avoiding the influence of the sway or deviation of the traction rope 33 on the movement of the hammer body 31, and further improving the accuracy and stability of the hammering.
[0038] In a second aspect, an embodiment of the present invention further provides a drilling method based on a drilling construction device for a pipe pile 60, comprising the following steps: S100: The pushing assembly 20 drives the push cylinder 21 to move upward so that a height space suitable for the pipe pile 60 to enter is obtained below the push cylinder 21; S200: After the pipe pile 60 is hoisted to the center of the tower 10, the push assembly 20 drives the push cylinder 21 to move downward and press against the top of the pipe pile 60; S300: Control the heavy hammer to drop into the pipe pile 60 and then start to reciprocate up and down to hammer the soil below the pipe pile 60 to form a hammer hole; S400: Control the jacking assembly 20 to output pressure to the push tube 21 to press the pipe pile 60 into the hammer hole; S500: loop through steps S300-S400 until the designed pile length is reached.
[0039] It should be noted that steps S100 to S500 form a coherent and clear construction process. First, the position of the push tube 21 is adjusted by the jacking assembly 20 to install the pipe pile 60, and then the soil is hammered with a heavy hammer to form a hole. Subsequently, the jacking assembly 20 presses the pipe pile 60 into the hole, and the operation is cyclical until the designed pile length is reached. An orderly process arrangement can avoid confusion and waiting time during the construction process, and each step is closely connected, which can improve the overall efficiency of the construction. By hammering the soil with a heavy hammer to form a hammer hole, the soil can be gradually broken and compacted according to the actual situation of the soil to form a relatively regular channel. Then the pipe pile 60 is pressed into the hammer hole, so that the pipe pile 60 is better combined with the surrounding soil, the friction and stability between the pipe pile 60 and the soil are improved, and the construction quality is guaranteed.
[0040] Compared with the prior art, the hole-drawing method of the pipe pile 60 hole-drawing construction device provided by the present invention realizes the continuous operation of hammering and pressing the pipe pile 60 by means of the coordinated control of the jacking assembly 20 and the heavy hammer assembly 30 by the controller 40. From installing the pipe pile 60 to hammering the soil, pressing the pipe pile 60, and then lifting the hammer body 31, the whole process is closely connected, and there is no need to wait for equipment conversion, which greatly shortens the construction period, improves construction efficiency, and meets the needs of efficient construction. The use of the controller 40 enables each step to be executed accurately, avoids excessive disturbance of the soil due to improper construction operation, reduces the occurrence of quality problems such as hole collapse, and ensures the quality and stability of the construction of the pipe pile 60. Various operations can be completed through the controller 40, reducing the operating difficulty and technical threshold of construction personnel, facilitating promotion and application in different construction projects, and promoting the upgrading and popularization of the pipe pile 60 construction technology.
[0041] In a possible implementation, in a possible implementation, S300 further includes: The hardness of the soil layer is detected and determined, and the up and down reciprocating stroke of the hammer body 31 is adjusted based on the hardness of the soil layer.
[0042] It should be noted that there is a difference in hardness between soft soil layers and hard soil layers. If a fixed hammer body 31 movement stroke is used, in hard soil layers, too small a stroke cannot effectively crush the soil. By detecting the hardness of the soil layer and adjusting the stroke, the hammer body 31 can be hammered with the most suitable energy in different soil layers, quickly crushing the soil to form a hammer hole, thereby significantly improving the construction efficiency. In hard soil layers, increasing the stroke can provide enough energy to crush the soil, so that the lead hole depth reaches the design standard, ensuring that the pipe pile 60 can be smoothly implanted, and improving the stability and bearing capacity of the entire foundation project. By adjusting the up and down reciprocating motion stroke of the hammer body 31 to find the most suitable hammer stroke, the soft soil can achieve the ideal density and crushing degree under the hammering action, which is conducive to the close combination of the pipe pile 60 with the surrounding soil after being pressed in, enhancing the friction and adhesion between the pipe pile 60 and the soft soil, and improving the bearing performance of the pipe pile 60.
[0043] In combination with the second aspect, in a possible implementation, when the hardness of the soil layer exceeds a set value, the hammer body 31 opens the soil extraction bin 311 to extract soil during the process of hammering the soil.
[0044] It should be noted that when encountering a hard soil layer with a hardness exceeding the set value, the resistance of the soil to the pipe pile 60 and the hammer 31 increases significantly. Opening the soil taking bin 311 to take soil can directly reduce the amount of soil under the hammer 31, reduce the resistance of the soil to the hammer 31 and the pipe pile 60, make it easier for the hammer 31 to hammer the soil, and the pipe pile 60 can be pressed in more smoothly, thereby speeding up the speed of the lead hole and the implantation of the pipe pile 60, greatly improving the construction efficiency. By taking soil to reduce the hardness and resistance of the soil, the hammer 31 can more effectively break the soil at each hammering, reduce the number of hammering required to reach the same lead hole depth, and further shorten the construction time. Taking soil reduces the pressure of the hard soil on the hammer 31 and the pipe pile 60, and reduces the impact force and friction of the hard soil layer on the hammer 31 and the pipe pile 60 during the hammering and pressing process. It helps to protect the structural integrity of the hammer 31 and the pipe pile 60, avoid damage caused by excessive force, and extend the service life of the equipment.
