[0033] See also Figure 1-10 The embodiment of the present invention provides a pile center positioning device. The pile center positioning device includes a support body 100, a measuring device 200, a plurality of supports 300 and a plurality of leveling units 400. The specific description of each component is as follows:

[0034] In this embodiment, the bracket body 100 includes a track 110 and a first center hole 120, the measuring device 200 includes at least four scale units 210 and a dial 220, and the multiple supports 300 each include a telescopic unit 310 and an embedded portion 320, the embedded portion 320 is arranged in the track 110, and the telescopic unit 310 is connected to the embedded portion 320; the four scale units 210 are all connected to the bracket body 100 and are arranged around the first center hole 120; the multiple scale units 210 are all provided with the leveling unit 400; the dial 220 is arranged above the first center hole 120, and the dial 220 includes a second center hole 133 and scale lines 221 distributed radially along the dial 220.

[0035] The scale unit 210 includes a scale, the middle of the scale unit 210 is a 0 scale, a plurality of scale units 210 are arranged around the outermost periphery of the support body 100, the support 300 is installed on the casing, the bottom of the support body 100 is equipped with a track 110, the embedded portion 320 of the support 300 is arranged in the track 110 of the support body 100, so that the support 300 is arranged at the bottom of the support body 100 and can be moved left and right along the track 110 of the support body 100 to be adjusted to a preset position of the support body 100 and fixed, the position of the support 300 in the support body 100 can be adjusted according to the diameter of the casing, and the plurality of supports 300 are all installed on the casing, so that the support body 100 and all structures on the support body 100 are relatively stable with the casing through the support 300. The support 300 also includes a telescopic unit 310, which can be extended and retracted up and down to adjust the vertical height of the bracket body 100. The leveling unit 400 is used to observe whether all the scale units 210 are at the same height; a dial 220 is also provided above the first center hole 120 of the bracket body 100. The dial 220 is a circular steel plate with scale values ​​distributed radially along the dial 220. A second center hole 133 is also provided in the center around the dial 220. When the two first protective plates 131 are closed and arranged on the first center hole 120 of the bracket body 100, the second center hole 133 is formed by the two first protective plates 131. The second center hole 133 can be used as a fixed conduit to facilitate workers to operate.

[0036] The working process of the pile center positioning device is as follows:

[0037] The pile center positioning device is hoisted above the casing, and the support 300 is moved left and right on the track 110 of the support body 100 to adjust so that multiple supports 300 can be set on the casing. After the support body 100 and the casing are connected and stabilized through the support 300, the leveling unit 400 on all the scale units 210 is observed, and the telescopic device of the support 300 is adjusted until all the scale units 210 are at the same height. By using the scale units 210 for positioning, in one embodiment, the measuring device 200 includes 4 scale units 210. 10, the middle 0 scales of the four scale units 210 intersect at a right angle to obtain the center point 703, and the pile center is aligned with the center point 703 to complete the assembly. The pile center is also the starting point drawn before construction; during the construction process, a line is drawn at the pile center to connect the preset scale values ​​on the scale plate 220, and recorded as the first connecting line 701. As the construction progresses, if the pile center deviates, one end of the first connecting line 701 will move with the pile center, and the deviated line is recorded as the second connecting line 702. The first connecting line 701 and the second connecting line 702 are connected by the first connecting line 701 and the second connecting line 702. 02 and the angle between the first connecting line 701 and the second connecting line 702 can be used to calculate the pile center offset distance at the casing mouth, and a weight 704 is used to be hung at the center point 703 to calculate the vertical offset angle 707. A right-angle member 706 is used, and the long side and short side of the right-angle member 706 are both known. The short side of the right-angle member 706 is usually equal to the radius of the second center hole 133. When the weight 704 is hung at the pile center and hits the hole wall 705, the short side of the right-angle member is vertically lowered along the line of the weight 704 until the straight The intersection of the long side and the short side of the angle member contacts the hole wall 705, and the angle between the long side of the right-angle member 706 and the hole wall 705 is equal to the offset angle 707. By measuring the distance from the opening of the hole wall 705 to the long side of the right-angle member 706 and the depth of the intersection of the long side and the short side of the right-angle member contacting the hole wall 705, the angle between the long side of the right-angle member 706 and the hole wall 705 can be obtained. The pile center offset distance at the bottom can be obtained through the offset angle 707, the pile center offset distance at the casing mouth and the sinking depth of the heavy hammer 704.

[0038] The support 300 supports left and right movement and can be adapted to casings of various diameters, and has good versatility; the overall height of the bracket body 100 can be adjusted through the support 300 and the leveling unit 400 on the scale unit 210, ensuring that the pile center positioning device can be accurately located at a certain horizontal height, and can be used as a qualified standard reference for subsequent observation of vertical offset and calculation of vertical offset value, and has strict data accuracy; the pile center can be obtained by pulling two perpendicular lines through the scale unit 210, and then one end of a line is pulled to connect with the pile, and the line is pulled to a certain scale of the dial 220, and the length and direction of the line are recorded. As the construction progresses, after the pile center deviates, the line is pulled to the scale, and the length and direction of the line are also recorded. The directions of the two recorded lines form an angle and two lengths, and the pile center offset distance at the casing mouth can be directly calculated. The whole process is convenient for line segment material collection, simple operation, and feasible; the offset situation can be intuitively seen according to the pulled line, so as to adjust the construction direction in time, which has the advantages of convenience and improved pile completion rate.

[0039] Continue to see Figure 1-10 In this embodiment, the bracket body 100 also includes a protective device 130, and the protective device 130 includes two first protective plates 131 and two second protective plates 132. The first protective plate 131 is connected to the second protective plate 132. The two first protective plates 131 are connected and are both arranged above the first center hole 120. The dial 220 is arranged between the two first protective plates 131, and the two second protective plates are respectively arranged on both sides of the first center hole 120.

[0040] Meanwhile, the first protection plate 131 is rotatably connected to the second protection plate 132 .

[0041] Specifically, the protective device 130 is arranged on the bracket body 100. Since the bracket body 100 is mainly a frame structure, it is not conducive to workers' operation. A first protective plate 131 and a second protective plate 132 are arranged above the bracket body 100 structure. First, the first protective plate 131 and the second protective plate 132 are hingedly connected, and the two second protective plates 132 are arranged on both sides of the first center hole 120 of the bracket body 100. The two first protective plates 131 form a hinge arranged above the first center, and the scale lines 221 of the dial 220 are respectively fixed on the two first protective plates 131, so that when the hinge formed by the two first protective plates 131 is closed, the dial 220 surrounds the second center hole 133. When the hinge formed by the two first protective plates 131 is opened, the catheter can be lowered into the first center hole 120 to perform the hole cleaning work.

[0042] Furthermore, the first protective plate 131 is provided with the leveling unit 400 .

[0043] Specifically, when the leveling unit 400 is arranged on the scale unit 210, it can ensure that the scale unit 210 is horizontal. The leveling unit 400 is installed on the first protective plate 131 to ensure that the first protective plate 131 is horizontal and to ensure that the scale plate 220 composed of two first protective plates 131 is in a horizontal state.

[0044] Furthermore, a cover plate 500 is included, and the cover plate 500 is detachably disposed above the second center hole 133 .

[0045] Specifically, considering that the overall mass of the pile center positioning device is relatively heavy, the factor of human movement is reduced. After the pile center positioning device is assembled, the device is directly placed on the casing. When the construction needs to be stopped during the pile foundation drilling process, it is only necessary to cover the second center hole 133 with the cover plate 500 to form a good protective effect.

[0046] Furthermore, it also includes a reinforcement device 600, and the reinforcement device 600 is connected to the first center hole 120 and the scale unit 210 respectively.

[0047] Specifically, the reinforcement device 600 refers to a structure disposed on both sides of the first central hole 120 of the bracket body 100 to enhance the stability of the scale unit 210 .

[0048] Furthermore, the reinforcement device 600 includes two fixed brackets 610, two connecting plates 620 and at least four connecting rods 630, the two fixed brackets 610 are respectively fixed on both sides of the first center hole 120 of the bracket body 100, the two connecting plates 620 are respectively detachably arranged on the two fixed brackets 610, the connecting rods 630 are respectively connected to the connecting plates 620 and the bracket body 100, and the scale unit 210 is respectively connected to the connecting plates 620 and the bracket body 100.

[0049] Meanwhile, the reinforcement device 600 further includes a fixing rod 640 , and the fixing bracket 610 is provided with a fixing hole 611 . The fixing rod 640 can pass through the fixing holes 611 of the two fixing brackets 610 in sequence.

[0050] Specifically, the fixed bracket 610 is fixed on both sides of the first center hole 120 of the bracket body 100, and is provided with a plurality of fixing holes 611. The fixing rod 640 can be passed through the fixing holes 611 of the two fixed brackets 610 in sequence to strengthen the stability of the two fixed brackets 610. Usually, the fixing rod 640 is a screw rod. The connecting plate 620 is placed on the fixed bracket 610 to form the aileron of the bracket body 100, and then the connecting rod 630 connects the bracket body 100 and the connecting plate 620 to fix the stability of the connecting plate 620. Then, the scale unit 210 is placed on the connecting plate 620 and the bracket body 100, so that the scale unit 210 can be arranged around the bracket body 100.

[0051] Furthermore, the support 300 further includes a clamping plate 330 , and the clamping plate 330 is disposed below the telescopic unit 310 .

[0052] Specifically, the bottom of the support 300 is a clamping plate 330 , and the support 300 is mainly clamped and fixed on the casing by the clamping plate 330 .

[0053] Furthermore, the leveling unit 400 is a bubble level.

[0054] Specifically, the principle of the bubble level is mainly gravity sensing, and is mainly used to measure whether an object is parallel to the horizontal plane up and down, and whether it is tilted left and right, so as to determine whether the measuring device 200 is on a horizontal plane.
