Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a construction device and a construction method for a pile foundation project. Background Art

[0002] A pile foundation is a deep foundation structure composed of piles and a pile cap, which is used to transfer the building load to a deep stable soil layer or rock stratum. During the building construction process, it is necessary to install the pile foundation through a pile driving device, and the installation verticality of the pile foundation needs to be detected during installation to improve the construction accuracy.

[0003] The patent specification with the publication number of CN220768195U discloses a pile foundation verticality detector, including a mounting plate and a detection mechanism; a containing box, which is vertically fixedly connected to the lower surface of the mounting plate; the detection mechanism includes a first motor, the first motor is vertically fixedly connected to the top of the inner wall of the containing box, and the output shaft of the first motor is vertically fixedly connected with a connecting rod, and the bottom end of the connecting rod rotatably extends below the containing box.

[0004] After the infrared rangefinder of this detection device is moved to the detection position of the pile foundation, the first motor drives the connecting rod to rotate, driving the infrared rangefinder to perform a circular motion to detect whether the end face of the pile foundation is inclined, so as to judge whether the pile foundation has a position offset; however, the disadvantage of this technical solution is that the detection of the vertical state of the pile foundation is related to the adjustment angle value of the mounting bracket of the infrared rangefinder, that is, by adjusting the height of the adjustable plug rod assemblies on both sides and cooperating with a spirit level, the infrared rangefinder is always adjusted to a horizontal state, but the specific inclination angle of the height adjustment difference between the two plug rods is unknown at this time. Then, based on this, the height of the pile foundation is measured. Although the height value of the pile foundation can be obtained, it cannot be compared with the adjustment angle of the infrared detector, and it is impossible to determine whether the pile foundation is vertical only based on the difference in height at different measurement positions. Summary of the Invention

[0005] The purpose of the present invention is to provide a construction device and a construction method for a pile foundation project, and the technical problems to be solved are as follows: When the existing pile foundation vertical detection device adjusts the infrared rangefinder to a horizontal state for detection, it can only measure the height of the pile foundation in the circumferential direction and cannot effectively determine whether the pile foundation is vertical.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A construction device for a pile foundation project includes a controller. The controller is electrically connected to a pile hammer. A detection mechanism is installed on one side of the pile hammer. The detection mechanism includes a displacement component. An inclination detection component is installed on one side of the bottom of the displacement component. The inclination detection component includes a plumb bob fixedly connected to the displacement component. A distance measurement component is installed on one side of the bottom of the displacement component. The distance measurement component includes a detection frame. A rotatable distance measuring instrument is installed on one side of the detection frame. The rotation axis of the distance measuring instrument is parallel to the rotation axis of the plumb bob.

[0007] As a further solution of the present invention: The displacement component includes two side support frames. A worm is rotatably connected between the tops of the two side support frames. A displacement box is sleeved in the middle of the worm. A displacement machine is installed in the middle of the displacement box. A worm gear built in the displacement machine meshes with the worm. A crank is installed outside the displacement machine. The inner side of the crank is fixedly connected to the worm gear.

[0008] As a further solution of the present invention: A displacement bin is provided in the middle of the displacement box. Both sides of the displacement box are fixedly connected to the adjacent sides of the displacement bin. Guide rods are slidably connected to the top and bottom of the displacement box. The ends of the two guide rods are fixedly connected to the adjacent side support frames.

[0009] As a further solution of the present invention: A handle is fixedly connected to the outside of the side support frame, and a bottom plate is fixedly connected to the bottom. A plurality of self-locking wheels are fixedly connected to the bottom surface of the bottom plate along the edge.

[0010] As a further solution of the present invention: The inclination detection component further includes an angle measuring scale fixedly connected to one side of the bottom surface of the displacement box. The side surface of the angle measuring scale is perpendicular to the bottom surface of the displacement box.

[0011] As a further solution of the present invention: The distance measurement component further includes a locking frame fixedly connected to the bottom surface of the displacement box. One end of the detection frame is fixedly connected to both sides of the locking frame. A micro motor is installed on one side of the detection frame. One end of the distance measuring instrument is fixedly connected to the output end of the micro motor, and the other end is rotatably connected to the detection frame.

[0012] As a further solution of the present invention: A leveling frame is fixedly connected to one side of the distance measuring instrument. A level is fixedly connected to the side of the leveling frame away from the displacement box. The micro motor is electrically connected to the controller. The level is always in a horizontal state.

[0013] A construction method for a construction device of a pile foundation project includes the following steps: S1. Move the pile hammer to the established pile hammering position and hammer and install the pile foundation. S2. Move the shifting component to a position on the circumferential side of the pile foundation, and adjust the position of the shifter to make it close to the pile foundation. S3. Adjust the rangefinder to a horizontal state, measure the height of the pile foundation, and the inclination detection component synchronously records the inclination at the current position. The inclination and the measured height are input into the controller in the form of group information. S4. Move the shifting component to another position on the circumferential side of the pile foundation, and repeat the subsequent operations. S5. The controller calculates the target value of the height difference at each point based on the inclination at each point, calculates the difference in the actually measured height at each location, compares the target value with the difference, and outputs the verticality of the pile foundation.

[0014] Advantages of the present invention: By electrically connecting the controller with the rangefinding component of the detection mechanism, installing both the inclination detection component and the rangefinding component at the bottom of the shifting box, and making the rotation direction of the plumb bob consistent with the rotation direction of the rangefinder. After the pile driving hammer hammers the pile foundation to the predetermined position, move the shifting component to multiple positions on the circumferential side of the pile foundation. Measure the inclination at each point through the inclination detection component, and at the same time measure the height of the pile foundation when the rangefinder is adjusted to the horizontal state. Input the measured height and inclination data into the controller in the form of group data. After the multi-point measurement is completed, the controller calculates the height difference of the pile foundation at the inclination positions when the pile foundation is vertical, and compares it with the actually measured height value, so as to obtain the data on whether the pile foundation is vertical and the offset direction, realizing the effective detection function of the verticality of the pile foundation. By installing a plurality of self-locking wheels on the side braces on both sides of the shifting component and installing a handle on the side brace, during the multi-point measurement along the pile foundation, the detection mechanism can be conveniently and roughly positioned. And after the rough positioning, the worm gear inside the crank is meshed with the worm to precisely position the detection positions of the inclination detection component and the rangefinding component, enabling the device to be conveniently moved to the proximal position of the pile foundation when detecting the height of the pile foundation, thereby reducing the error of the verticality detection and improving the detection accuracy.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1 to 5 shown, a construction device for pile foundation engineering includes a controller 1. The controller 1 is electrically connected to a pile hammer 2. A detection mechanism is installed on one side of the pile hammer 2. The detection mechanism includes a displacement assembly 3. An inclination detection assembly 4 is installed on one side of the bottom of the displacement assembly 3. The inclination detection assembly 4 includes a plumb bob 41 fixedly connected to the displacement assembly 3. A distance measuring assembly 5 is installed on one side of the bottom of the displacement assembly 3. The distance measuring assembly 5 includes a detection frame 51. A rotatable distance measuring instrument 52 is installed on the detection frame 51. The rotation central axis of the distance measuring instrument 52 is parallel to the rotation central axis of the plumb bob 41; It should be noted that the controller 1 and the distance measuring instrument 52 are electrically connected. That is, when the distance measuring instrument 52 performs distance detection, this part of the data can be transmitted back to the controller 1. The pile hammer 2 is hydraulically driven and is installed on the operating platform of the pile driver during use. The controller 1 is electrically connected to the operating platform. By moving the rotation position of the operating platform through the controller 1, the lateral movement of the pile hammer 2 is realized. Also, the pile hammer 2 is electrically connected to the controller 1 and can be vertically moved under the control of the controller 1. The pile hammer 2 and the operating platform are usually integrally installed on a crawler-type mobile device. This part is prior art; the pile hammer 2 successively includes structures such as a hydraulic cylinder 21, an accumulator 22, a piston rod 23, a hammer core 24, and a hammer cap 25 from top to bottom (see Figure 2 ). During pile driving, the hammer cap 25 is butted against the pile cap, and the piston rod 23 is energized and impacted by means of the hydraulic cylinder 21 and the accumulator 22 to realize the pile driving function.

[0020] As Figure 1 and Figure 3As shown in the figure, the displacement assembly 3 includes two side brackets 31. A worm 32 is rotatably connected between the tops of the two side brackets 31. A displacement box 33 is sleeved in the middle of the worm 32. A displacement machine 34 is installed in the middle of the displacement box 33. A worm gear is built in the displacement machine 34 and meshes with the worm 32. A crank 35 is installed on the outside of the displacement machine 34, and the inner side of the crank 35 is fixedly connected to the worm gear; A displacement bin is arranged in the middle of the displacement box 33. Both sides of the displacement box 33 are fixedly connected to the adjacent sides of the displacement bin. Guide rods 36 are slidably connected to the top and bottom ends of the displacement box 33. The ends of the two guide rods 36 are fixedly connected to the adjacent side brackets 31; A handle 37 is fixedly connected to the outside of the side bracket 31, and a bottom plate 38 is fixedly connected to the bottom. Four self-locking wheels 39 are fixedly connected to the bottom surface of the bottom plate 38 along the edge; It should be noted that when the pile hammer 2 is performing pile foundation hammering, the staff transfers the position of the displacement assembly 3 by holding the handle 37 to move to the pile foundation position. Then, the horizontal position of the displacement machine 34 is adjusted by rotating the crank 35. The built-in worm gear of the displacement machine 34 meshes with the worm 32 to achieve the displacement function. And during the movement, restricted by the guide rods 36 at the top and bottom ends, until it moves to the established detection position, the lock buckle of the self-locking wheel 39 is buckled, and then the vertical detection is carried out.

[0021] As Figures 3 to 5 shown, the inclination detection assembly 4 further includes an angle measuring ruler 42 fixedly connected to one side of the bottom surface of the displacement box 33. The side surface of the angle measuring ruler 42 is perpendicular to the bottom surface of the displacement box 33, and angle scales are marked on the side close to the plumb bob 41; It should be noted that when the guide rod 36 of the displacement assembly 3 is in a parallel state with the horizontal plane, the connecting line of the plumb bob 41 is in the same vertical plane as the 90 degrees marked on the angle measuring ruler 42. In this way, it is ensured that when the displacement assembly 3 is in an inclined state as a whole, the deflection angle of the plumb bob 41 can be measured by the angle measuring ruler 42, so as to achieve the function of detecting the inclination of the displacement assembly 3.

[0022] The distance measuring assembly 5 further includes a locking frame 53 fixedly connected to the bottom surface of the displacement box 33. Both sides of the detection frame 51 are fixedly connected to one end of the locking frame 53. A micro motor 54 is installed on one side of the detection frame 51. One end of the distance measuring instrument 52 is fixedly connected to the output end of the micro motor 54, and the other end is rotatably connected to the detection frame 51; A leveling frame 55 is fixedly connected to one side of the distance measuring instrument 52. A level 56 is fixedly connected to the side of the leveling frame 55 away from the displacement box 33. The micro motor 54 is electrically connected to the controller 1, and the level 56 is always in a horizontal state; It should be noted that during the pile driving of the pile hammer 2, in order to accurately detect the levelness of the pile foundation, it is necessary to take multiple samples along the circumferential side of the pile foundation. By detecting the heights at these multiple points, it is possible to determine whether the pile foundation is in a vertical state. During the actual detection process, due to the differences in the levelness at different positions on the circumferential side of the pile foundation, or the pile foundation itself being installed on an inclined plane with an inclination angle, as described above, the plumb bob 41 and the angle measuring ruler 42 can detect the inclination angles at each point. Moreover, the rotation point of the plumb line installed at the top of the plumb bob 41 and the locking bracket 53 for installing the rangefinder 52 are both located on the bottom surface of the displacement box 33, and the rotation axis of the plumb bob 41 is parallel to the rotation axis of the rangefinder 52 by the micro motor 54. At this time, the deflection angle measured by the plumb bob 41 is the inclination angle of the position where the rangefinder 52 detects the height. The staff inputs the ground inclination angles measured by the angle measuring ruler 42 at each point and the pile foundation heights measured by the rangefinder 52 into the controller 1 in the form of a group of information one by one. The data processor inside the controller 1 calculates the reference height at each point when the pile foundation is in a vertical state based on the inclination angle, and then compares it with the actual measured height by the rangefinder 52, so as to determine whether the pile foundation is in a vertical state and the inclination direction.

[0023] A construction method for a pile foundation engineering construction device includes the following steps: S1. Move the pile hammer 2 to the established pile driving position and drive the pile foundation for installation; S2. Move the displacement assembly 3 to a position on the circumferential side of the pile foundation, and adjust the position of the displacement machine 34 to make it close to the pile foundation; S3. Adjust the rangefinder 52 to a horizontal state, measure the height of the pile foundation, and the inclination detection assembly 4 synchronously records the inclination angle at the position. The inclination angle and the detected height are input into the controller 1 in the form of a group of information; S4. Move the displacement assembly 3 to another position on the circumferential side of the pile foundation and repeat the subsequent operations; S5. The controller 1 calculates the target value of the height difference at each point based on the inclination angles at each point, calculates the difference in the actual detected height at each location, compares the target value with the difference, and outputs the verticality of the pile foundation.
