Description

Technical Field

[0001] The invention relates to the technical field of cement foundation pile detection, in particular to a coring device for cement foundation pile detection. Background Art

[0002] Concrete cast-in-place piles are the most common type of foundation piles, and are usually tested through the core drilling method. A complete and successful core drilling test can obtain the pile length, pile body concrete strength, pile bottom sediment thickness and pile body integrity, and determine or identify the geotechnical properties of the bearing layer at the pile end; the core drilling method test uses core drilling equipment to drill holes in the foundation piles to take out sample columns. After the sample columns are taken out, the sample columns are analyzed and identified to complete the foundation pile test.

[0003] For example, a pile detection device for construction engineering with publication number CN114837239A and a method for using the same, wherein a pressure plate mechanism is provided on a mounting frame, and a pressure plate in the pressure plate mechanism can contact the ground to increase the stability of the device during sampling; the pressure plate mechanism is used to control the flipping of the universal wheel, and before the pressure plate contacts the ground, the universal wheel leaves the ground, so that the fixed block contacts the ground, further increasing the contact area between the device and the ground, and reducing the descent of the pressure plate, thereby improving stability; a locking mechanism is provided on the core drilling mechanism to limit the operation of the core drilling mechanism, and a linkage mechanism is provided to link the state of the pressure plate with the state of the locking mechanism, thereby controlling the timing of core drilling sampling of the core drilling mechanism, and ensuring that only when the pressure plate contacts the ground and the universal wheel is flipped and retracted, the sleeve in the core drilling mechanism can be lowered to complete core sampling, and during core sampling, the pressure plate and the fixed block are both in contact with the ground to improve stability; By setting the second rack and the sliding rod to be an adjustable fixed connection, when the pressure plate contacts the ground and it is necessary to change the sampling point, the relative sliding between the sliding rod and the first rack can be released by removing the screws in the threaded hole, thereby avoiding the state in which the sliding adjustment of the support frame interferes with the pressure plate. However, in actual use, during the core drilling process, the speed of drilling or the size of the drilling resistance will affect the verticality of the core, and it is very likely that a certain offset will occur during the drilling process, and then the verticality cannot be measured during the core drilling process. In the prior art, the verticality can be measured by the theodolite during the core drilling process, but the measurement steps are relatively cumbersome and inconvenient to operate. The verticality can also be measured by the hanging line method. When measuring the verticality by the hanging line method, if the core drilling deviates and the staff cannot be reminded in time, the core drilling will be tilted, which will affect the accuracy of the coring and the subsequent detection, and there are certain defects in use.

[0004] Therefore, we propose a coring device for cement foundation pile detection in order to solve the above-mentioned problems. Summary of the invention

[0027] Compared with the prior art, the present invention has the following beneficial effects: the coring device for cement pile detection is provided with measuring components on the top and one side of the fixing frame, so that when coring the cement pile, the verticality of the core drilling mechanism can be measured in real time during the coring process, and if there is any skewness, the staff can be reminded in time, so that timely adjustment is facilitated to avoid the skewness of the core drilling affecting the accuracy of coring, thereby improving the practicality;

[0028] 1. Measuring components are set on the top and one side of the fixed frame. When coring the foundation pile, the base is moved by rollers, and then two sets of hydraulic push rods can be started to drive the movable plate to move downward. After the movable plate moves downward, the positioning column is inserted into the soil, and then the roller is separated from the ground to support and fix the base. Then the core drilling mechanism can be started, and then the drive motor is started to drive the threaded rod to rotate through the rotating shaft. After the threaded rod rotates, the core drilling mechanism can be driven to move through the threaded connection with the movable seat. The feed of the core drilling mechanism can be controlled, and the feed speed can be controlled. If skew occurs during the coring process, the base and the fixed frame will have a certain degree of skew, the spherical part can rotate on the mounting plate, and the counterweight block can always be perpendicular to the horizontal plane. After the fixed frame tilts, the mounting plate and the mounting frame tilt. Under the action of the counterweight block, the crossbeam can be parallel to the horizontal plane. If skew occurs, the movable plate will be skewed. The movable plate can be pushed upward by the cross frame under the action of the cross frame, and the metal cover can be driven upward after the movable plate is moved up. The rotation of the rotating shaft can drive the rotating rod to rotate through the meshing of the first bevel gear and the second bevel gear. The rotation of the rotating rod drives the connecting frame and the moving rod to rotate. After the metal cover rises, it can contact the metal block. The metal cover can be knocked by the rotation of the metal block, and then a sharp sound can be made, which can timely remind the staff that the drill core is skewed, and then stop the operation of the drill core mechanism. According to the angle between the cross frame and the movable plate, the corresponding hydraulic push rod can be adjusted to adjust the angle of the base. Through the measuring component, when coring the cement foundation pile, the verticality of the drill core mechanism can be measured in real time during the coring process. If skew occurs, the staff can be reminded in time, which is convenient for timely adjustment, so as to avoid the skew of the drill core affecting the accuracy of coring, thereby improving practicality.

[0029] 2. During the core drilling process, there is a certain distance between the movable plate and the crossbar. The impact generated during the core drilling process will cause the spherical part to shake slightly to a certain extent. After the tilt occurs, the crossbar rotates to push the movable plate upward, and the U-shaped frame can be driven to move by rotating the screw. After the U-shaped frame slides on the mounting plate, the height of the movable plate can be adjusted. Then, the distance between the crossbar and the movable plate can be adjusted according to the rotation speed and feed speed of the core drilling mechanism, so as to avoid the crossbar accidentally pushing the movable plate upward during the core drilling process, thereby improving practicality.

[0030] 3. When supporting and positioning the base, after the positioning column is inserted into the ground, one end of the mounting rod contacts the ground surface, and then the positioning column continues to be inserted into the ground under the action of the gravity of the base, and the mounting rod and the movable block can slide in the mounting groove, which can compress the telescopic spring and the telescopic rod. After the movable block moves up, it can drive the connecting rod to rotate, and after the two connecting rods rotate, they can pull the two positioning rods away from each other, so that the two positioning rods can be inserted into the soil, so that the positioning column can be positioned, and the positioning column will not easily fall off the ground, which can improve the stability of subsequent core drilling and improve practicality.

[0053] Embodiment 1: Figure 1-Figure 7 As shown, a measuring assembly 2 is arranged on the top and one side of the fixing frame 102. When coring the foundation pile, the base 1 is moved by the roller 101, and then the two sets of hydraulic push rods 302 can be started to drive the moving plate 303 to move downward. After the moving plate 303 moves downward, the positioning column 305 is inserted into the soil, and then the roller 101 is separated from the ground, so that the base 1 is supported and fixed, and then the core drilling mechanism 106 can be started, and then the driving motor 202 is started to drive the threaded rod 107 to rotate through the rotating shaft 203. After the threaded rod 107 rotates The core drilling mechanism 106 can be driven to move by the threaded connection with the movable seat 105, and the feeding of the core drilling mechanism 106 can be controlled, and the feeding speed can be controlled.

[0058] Embodiment 3: Figure 8-Figure 9 As shown, when the base 1 is supported and positioned, after the positioning column 305 is inserted into the ground, one end of the mounting rod 310 contacts the ground surface, and then the positioning column 305 continues to be inserted into the ground under the action of the gravity of the base 1, and the mounting rod 310 and the movable block 309 can slide in the mounting groove 306, and the telescopic spring 308 and the telescopic rod 307 can be compressed. After the movable block 309 moves upward, it can drive the connecting rod 311 to rotate, and the two connecting rods 311 can pull the two positioning rods 313 away from each other after rotation, so that the two positioning rods 313 can be inserted into the soil, so that the positioning column 305 can be positioned, so that the positioning column 305 will not easily fall off the ground, which can improve the stability of subsequent core drilling and improve practicality.

[0059] Working principle: When using the coring device for cement pile testing, first, according to Figure 1-Figure 9As shown, a measuring assembly 2 is arranged on the top and one side of the fixed frame 102. When coring the foundation pile, the base 1 is moved by the roller 101, and then the two sets of hydraulic push rods 302 can be started to drive the movable plate 303 to move downward. After the movable plate 303 moves downward, the positioning column 305 is inserted into the soil, and then the roller 101 is separated from the ground, so that the base 1 is supported and fixed, and then the core drilling mechanism 106 can be started, and then the driving motor 202 is started, and the threaded rod 107 is driven to rotate by the rotating shaft 203. After the threaded rod 107 rotates, the core drilling mechanism 106 can be driven to move through the threaded connection with the movable seat 105, and the feed of the core drilling mechanism 106 can be controlled, and the feed speed can be controlled. If skew occurs during the coring process, the base 1 and the fixed frame 102 will have a certain degree of skew, the spherical member 207 can rotate on the mounting plate 205, and the counterweight block 209 can always be perpendicular to the horizontal plane. The fixed frame 102 is installed after being tilted. The plate 205 is tilted with the mounting frame 206. Under the action of the counterweight 209, the cross frame 210 can be parallel to the horizontal plane. If it is skewed, the movable plate 211 is skewed and abuts against the cross frame 210. Under the action of the cross frame 210, the movable plate 211 can be pushed up to move up. After the movable plate 211 moves up, the metal cover 215 is driven to move up. The rotation of the rotating shaft 203 can drive the rotating rod 216 to rotate through the meshing of the first bevel gear 204 and the second bevel gear 218. The rotation of the rotating rod 216 drives the connecting frame 219 and the moving rod 220 to rotate. After the metal cover 215 rises, it can contact the metal block 222. The metal block 222 rotates to knock the metal cover 215, and then a sharp sound can be emitted, which can timely remind the staff that the drilling core is skewed. Then, the operation of the core drilling mechanism 106 is stopped. According to the angle between the cross frame 210 and the movable plate 211, the corresponding hydraulic push rod 302 can be adjusted to adjust the angle of the base 1.

[0060] During the core drilling process, there is a certain distance between the movable plate 211 and the crossbar 210. The impact generated during the core drilling process will cause the spherical member 207 to shake slightly to a certain extent. After the tilt occurs, the crossbar 210 rotates to push the movable plate 211 upward to move, and the rotating screw 225 can drive the U-shaped frame 223 to move. After the U-shaped frame 223 slides on the mounting plate 205, the height of the movable plate 211 can be adjusted. When the base 1 is supported and positioned, the positioning column 305 is inserted into the ground and the mounting rod 310 is installed. One end is in contact with the ground surface, and then the positioning column 305 continues to be inserted into the ground under the action of gravity of the base 1. The mounting rod 310 and the movable block 309 can slide in the mounting groove 306, and the telescopic spring 308 and the telescopic rod 307 can be compressed. After moving up, the movable block 309 can drive the connecting rod 311 to rotate. After rotating, the two connecting rods 311 can pull the two positioning rods 313 away from each other, so that the two positioning rods 313 can be inserted into the soil, so that the positioning column 305 can be positioned.
