Description

Technical Field

[0001] This utility model relates to the field of bored pile construction technology, specifically to a verticality detection device for ultra-long bored pile construction. Background Technology

[0002] With the increasing demand for deep foundation bearing capacity in high-rise buildings and large bridge projects, bored pile construction technology has gradually developed. It forms pile holes through mechanical drilling, inserts steel cages, and then pours concrete to form piles. It effectively solves the construction problems of traditional pile foundations under complex geological conditions. Its core advantage lies in its strong adaptability. It can be applied to various environments such as soft soil, sand, and rock. Moreover, it does not require large-scale excavation during construction, reducing the disturbance to the surrounding environment. It is especially suitable for operation in densely populated urban areas.

[0003] During the construction of bored piles, it is usually necessary to check the verticality of the borehole wall. Existing technology typically uses a CNC winch mounted above the borehole to lower an ultrasonic borehole probe into the borehole. The probe emits ultrasonic waves and receives reflected signals from the borehole wall, measuring the distance from the probe to the borehole wall. The CNC winch then moves the probe vertically, simultaneously recording depth data to determine the verticality of the borehole wall. However, when the CNC winch is mounted above the borehole, a temporary support rail is usually erected before moving the winch from outside the borehole to above it using the support rail. But when the borehole diameter is large, the distance between the outer edge of the borehole and the center is significant, making it inconvenient to manually move the winch to above the borehole. Furthermore, when the winch is above the support rail and far from the outer edge of the borehole, it is also inconvenient to retract it. Therefore, a verticality detection device for ultra-long bored pile construction is proposed to solve these problems. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A verticality testing device for ultra-long bored pile construction includes a bored pile hole testing instrument, and a support mechanism is provided on one side of the bored pile hole testing instrument.

[0006] The support mechanism includes two support plates. Each support plate has an adjusting lug rotatably connected to the same end. Each adjusting lug has pin holes at both ends. Each support plate has a pad fixedly installed on the center and both sides of its bottom surface. Each pad has a mounting groove on its bottom surface, and each pad is rotatably connected to a caster wheel inside the mounting groove. The bottom ends of the casters extend to the bottom of the pad.

[0007] As a further embodiment of this utility model: a support block is fixedly connected to the side of each of the support plates near the center. A fastening bolt is inserted into and threadedly tightened at the center of the bottom surface of the support block. An anti-slip pad is connected through the outer wall of the fastening bolt. A scissor-type connecting rod is also connected through the outer wall of the fastening bolt. One side connecting shaft of the scissor-type connecting rod is rotatably connected to the bottom surface of the support plate. The other side connecting shaft of the scissor-type connecting rod is slidably connected to a limit rail. The limit rail extends along the length direction of the support plate.

[0008] As a further embodiment of this utility model: the end of the fastening bolt abuts against the bottom surface of the middle part of the scissor-type connecting rod through an anti-slip pad, and the top surface of the middle part of the scissor-type connecting rod abuts against the bottom surface of the support plate, and the bottom surface of the fastening bolt is located above the bottom surface of the pad.

[0009] As a further embodiment of this utility model: a guide groove is provided in the middle of the top surface of each of the support plates, the guide groove extends along the length of the support plate as a whole, and a slope is provided on the side of the guide groove away from the adjusting ear.

[0010] As a further embodiment of this utility model: threaded sleeves are fixedly installed on both sides of the support plate away from the support block, and a lead screw is threaded through and connected to the inner wall of each threaded sleeve. A knob is fixedly connected to one end of the lead screw, and a counterweight claw is rotatably connected to the other end of the lead screw.

[0011] As a further embodiment of this utility model: a positioning hole is provided on the surface of the counterweight claw and at one end near the rotating shaft, and a positioning shaft is fixedly connected to the middle of the top surface of the threaded sleeve. The positioning shaft extends along the length direction of the threaded sleeve and is inserted into the positioning hole.

[0012] As a further embodiment of this utility model: the grouting pile hole forming detection instrument includes a probe lifting CNC winch, the lower end of which is fixedly connected to an ultrasonic aperture probe by a rope, the ultrasonic aperture probe extending to the bottom of the probe lifting CNC winch, and support wheels are provided around the bottom surface of the probe lifting CNC winch.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model uses two support plates to support and guide the probe lifting CNC winch base. One end of the support plate is provided with an adjustment ear with a pin hole. After the adjustment ear is fixed to the edge of the borehole by the pin, the support plate can rotate relative to the adjustment ear. When the support plate rotates to the ground outside the borehole, it is convenient for the operator to push the probe lifting CNC winch above the support plate. Then, the support plate is rotated to move above the borehole. During this period, the support plate can carry the CNC winch to move above the borehole. In addition, after the borehole verticality test is completed, the support plate is rotated away from the borehole. The support plate can then drive the CNC winch to move to the ground, which is convenient for the operator to retrieve the CNC winch.

[0015] (2) The distance between the two support plates can be adjusted. When the distance between the support plates is reduced, it is easier to store the equipment. In addition, multiple casters are set at the bottom of the support plates, which facilitates the transportation of the support plates and improves the practicality of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, a verticality testing device for ultra-long bored pile construction includes a bored pile hole testing instrument 1. A support mechanism 2 is provided on one side of the bored pile hole testing instrument 1. The support mechanism 2 includes two support plates 201. Each support plate 201 has an adjusting lug 211 rotatably connected to the same end. Each adjusting lug 211 has pin holes 212 at both ends of its surface. Each support plate 201 has feet 207 fixedly installed on its bottom surface, with mounting grooves on the bottom surface. Each foot 207 is rotatably connected to a caster wheel 208 inside the mounting groove. The bottom ends of the caster wheels 208 extend below the foot 207. Figures 1-3 As shown, in order to avoid interference when the two support plates 201 rotate, only one pin is inserted into the pin hole 212 on the surface of the adjusting ear 211 to connect to the ground, and the caster wheel 208 contacts the ground, thereby preventing the support plate 201 from being worn by the ground.

[0025] Each support plate 201 has a support block 202 fixedly connected to its side near the center. A fastening bolt 203 is inserted into and threadedly tightened at the center of the bottom surface of each support block 202. An anti-slip pad 204 is threaded through the outer wall of the fastening bolt 203. A scissor-type connecting rod 205 is also threaded through the outer wall of the fastening bolt 203. One side of the scissor-type connecting rod 205 is rotatably connected to the bottom surface of the support plate 201, while the other side is slidably connected to a limit rail 206. The limit rail 206 extends along the length of the support plate 201. Figures 3-4 As shown, the scissor link 205 consists of two straight links that rotate relative to each other, with the pivot and groove located in the middle of the straight links. The fastening bolt 203 can pass through the pivot in the middle of the scissor link 205. The limiting rail 206 has a limiting groove structure inside to prevent the connecting shaft of the scissor link 205 from coming off.

[0026] The end of the fastening bolt 203 abuts against the bottom surface of the middle part of the scissor-type connecting rod 205 via the anti-slip pad 204, and the top surface of the middle part of the scissor-type connecting rod 205 abuts against the bottom surface of the support plate 201. The bottom surface of the fastening bolt 203 is located above the bottom surface of the pad 207. Figures 2-3As shown, when the support mechanism 2 is stored, the fastening bolt 203 is connected to the threaded hole on the bottom surface of the support block 202, and at this time the distance between the two support plates 201 is the smallest. After the scissor link 205 drives the distance between the support plates 201 to increase, the nut and the fastening bolt 203 can be used together to lock the central pivot of the scissor link 205.

[0027] Each support plate 201 has a guide groove 209 in the center of its top surface. The guide groove 209 extends along the length of the support plate 201. A slope 210 is provided on the side of the guide groove 209 away from the adjusting lug 211. Figure 2 As shown, slope 210 serves as the transition surface between guide channel 209 and the ground surface.

[0028] Threaded sleeves 213 are fixedly installed on both sides of the support plate 201 on the side away from the support block 202. Each threaded sleeve 213 has a threaded rod 214 threaded through and connected to its inner wall. A knob 215 is fixedly connected to one end of the screw 214, and a counterweight pawl 216 is rotatably connected to the other end of the screw 214. Figure 2 As shown, when the support plate 201 is erected above the borehole, the threaded sleeve 213 is close to the borehole wall or located above the ground surface, making it convenient for operators to access and push the counterweight claw 216.

[0029] A positioning hole 217 is provided on the surface of the counterweight claw 216 near the end of the rotating shaft. A positioning shaft 218 is fixedly connected to the center of the top surface of the threaded sleeve 213. The positioning shaft 218 extends along the length of the threaded sleeve 213 and is inserted into the positioning hole 217. Figure 5 As shown, the counterweight claw 216 can rotate upwards and is easy to store.

[0030] The bored pile hole testing instrument 1 includes a probe lifting CNC winch 101. An ultrasonic aperture probe 102 is fixedly connected to the lower end of the probe lifting CNC winch 101 via ropes. The ultrasonic aperture probe 102 extends below the probe lifting CNC winch 101. Support wheels are provided around the bottom surface of the probe lifting CNC winch 101. Figure 1 As shown, the bored pile hole testing instrument 1 can be the existing TS-K100QC(W) bored pile hole testing instrument. The working principle and specific usage method of the probe lifting CNC winch 101 and ultrasonic aperture probe 102 are both in the public knowledge field, so they will not be described in detail.

[0031] The working principle of this utility model:

[0032] When using the device, first adjust the distance between the two support plates 201, loosen the fastening bolts 203 at the bottom of the disassembly support block 202, then adjust the included angle between the two connecting rods inside the scissor-type connecting rod 205, and slide one side of the scissor-type connecting rod 205 along the inside of the limiting rail 206, thereby widening the distance between the two support plates 201. When fixing the distance between the support plates 201 again, the fastening bolts 203 and the anti-slip pads 204 can be passed through the pivot in the middle of the scissor-type connecting rod 205, and then the nuts are installed and tightened at the end of the fastening bolts 203, thereby locking the scissor-type connecting rod 205 and fixing the distance between the support plates 201.

[0033] Next, move the two support plates 201 above the borehole, with the adjusting lugs 211 and the casters 208 away from the supporting lugs supporting the ground. Then, insert a pin into one of the adjusting lugs 211 through the pin hole 212 and fix it to the ground. After that, push the support plate 201 away from the borehole. During this process, the two support plates 201 rotate relative to the fixed adjusting lug 211 until the support plate 201 is completely transferred above the ground. Then, push the probe lifting CNC winch 101 to move to the slope 210, and then to the middle of the guide groove 209. After that, push the support plate 201 to rotate around the fixed adjusting lug 211. When the support plate 201 is moved above the borehole, the CNC winch 101 for lifting the probe is moved to the top of the borehole. Then, the screw 214 is rotated and advanced within the threaded sleeve 213 by the knob 215. The positioning shaft 218 is disengaged from the positioning hole 217. The counterweight claw 216 is gently pushed so that it rotates 180 degrees under the action of gravity and hangs down naturally. After the counterweight claw 216 is inside the borehole, the knob 215 is rotated in the opposite direction. The screw 214 moves along the threaded sleeve 213, and the counterweight claw 216 abuts against the top of the borehole wall, thereby locking the support plate 201 with the borehole support and preventing the support plate 201 from rotating or shaking relative to the adjusting ear 211.

[0034] Finally, the operator uses the control panel on the outside of the equipment to operate the probe lifting CNC winch 101 to lower the ultrasonic aperture probe 102 between the two support plates 201. As the ultrasonic aperture probe 102 continues to fall, it falls vertically into the borehole and collects the verticality data of the borehole wall.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
