[0001] This utility model relates to the field of auxiliary components for CFG pile quality control, specifically to a CFG pile quality control raw material bearing capacity testing device. Background Technology

[0002] CFG piles are cement-fly ash-gravel piles, made from crushed stone, stone chips, sand, fly ash, cement, and water, mixed with various pile-forming machines to achieve a certain strength. CFG piles are a type of low-strength concrete pile that can fully utilize the bearing capacity of the soil between the piles and transfer loads to deeper foundation layers. They possess good technical performance and economic benefits, and are widely used in areas with poor groundwater quality.

[0003] In the actual manufacturing process of CFG piles, before they are put into use, it is necessary to test whether their overall bearing capacity meets the standards. However, the existing testing devices are not designed to quickly center and fix the CFG piles, which can cause the testing position to shift during the testing process, resulting in certain errors in the testing. Utility Model Content

[0007] The top assembly of the pushing guide component is provided with a pile fixing component for centering and clamping the CFG pile.

[0008] The top surface of the base is provided with a pile driving component and a pile detection component on both sides. The pile driving component and the pile detection component are located on both sides of the pile fixing component, and are used to test the bearing capacity of the CFG pile clamped in the pile fixing component.

[0009] Preferably, the pushing guide assembly includes a fixed plate, a guide seat, and a lifting cylinder. The fixed plate is horizontally fixed in the middle of the top surface of the base, and a guide groove is opened in the horizontal direction on the top surface of the fixed plate. The guide seat is placed in the guide groove in a horizontal sliding fit, and the lifting cylinder is vertically fixed on the top surface of the guide seat. The lifting push rod at the top of the lifting cylinder is vertically arranged, and the pile fixing assembly is fixed at the top end.

[0010] Preferably, the two ends of the fixing plate are close to the pile pushing component and the pile detection component, respectively, and the guide groove is either a dovetail groove or an I-shaped groove.

[0011] Preferably, both sides of the base are flatly extended and fixed with connecting plates for fixing in the setting position.

[0012] Preferably, the pile fixing assembly includes a fixed clamp, a movable clamp, and a U-shaped bracket. The top end of the lifting push rod is horizontally fixed to the fixed clamp. The movable clamp is suspended parallel above the fixed clamp, with the two facing each other vertically. The end faces of the movable clamp and the fixed clamp are horizontally provided with clamping grooves. The front and rear end faces of the fixed clamp are horizontally extended and fixed with mounting plates. The U-shaped bracket is inverted and fixed between the mounting plates at the front and rear positions. The top horizontal part of the U-shaped bracket is vertically fitted with an adjusting stud by threaded connection. The bottom end of the adjusting stud is coaxially rotatably connected to a bearing seat, and the bearing seat is fixed in the middle of the top surface of the movable clamp.

[0013] Preferably, the clamping grooves are all through grooves in the lateral direction, and all the clamping grooves are V-shaped grooves.

[0014] Preferably, each of the adjusting studs is coaxially mounted with a handwheel for easy handling, and each portion of the adjusting stud extending beyond the top surface of the horizontal part of the U-shaped bracket is coaxially engaged with a locking nut.

[0015] Preferably, the top of the U-shaped bracket has vertically opened guide holes at both the front and rear positions of the adjusting stud. Each guide hole has a guide rod inserted vertically and coaxially in a sliding fit, and the guide rod is fixed to the top surface of the movable clamp.

[0016] Preferably, the pile pushing assembly includes a side seat and a pushing cylinder. The side seat is vertically fixed along the longitudinal direction on one side of the top surface of the base. The pushing cylinder is horizontally fixed on the upper outer side of the side seat. The pushing rod of the pushing cylinder passes through the inner side of the side seat in a horizontal sliding fit. At the same time, a push plate is vertically fixed along the longitudinal direction at the end of the pushing rod near the pile fixing assembly.

[0017] Preferably, the pile testing assembly includes a testing support and a bearing capacity testing instrument body. The testing support is vertically fixed along the longitudinal direction on the other side of the top surface of the base. The bearing capacity testing instrument body is embedded and fixed on the inner side of the testing support near the pile fixing assembly. A testing probe with its axis arranged in the transverse direction is arranged on the side of the bearing capacity testing instrument body. At the same time, the axis of the testing probe and the lowest edge of the clamping groove are located in the same transverse vertical plane. A control panel for adjusting the bearing capacity testing instrument body is installed on the front of the testing support, and the control panel is electrically connected to the bearing capacity testing instrument body.

[0018] The aforementioned CFG pile quality control material bearing capacity testing device, specifically used for testing CFG piles, features a pile fixing assembly. Both the fixed and movable clamps of this assembly have V-shaped clamping grooves. By bringing the movable clamp closer to the fixed clamp, the CFG pile can be quickly and accurately centered and clamped. This centering and clamping method is simple and easy to implement, preventing positional shifts during testing. This arrangement helps avoid detection errors. Furthermore, by rotating the adjusting stud in both directions, the movable clamp can move closer to or further away from the fixed clamp, thus enabling the clamping and loosening of the CFG pile. The clamping and loosening operation of the CFG pile is simple and easy to implement, facilitating both quick centering and clamping of the CFG pile for testing and easy release and removal of the CFG pile after testing. Moreover, because the lower part of the pile fixing assembly is equipped with a pushing guide component with lifting and adjusting function, it allows for... The guide seat of the pushing guide assembly slides laterally along the guide groove, which can guide the CFG pile during the testing process and prevent the CFG pile from deviating during the testing. At the same time, the lifting push rod of the lifting cylinder can drive the pile fixing assembly and the CFG pile to adjust their position and height, so as to make the CFG pile concentric with the detection probe of the pile detection assembly. This ensures that the bearing capacity of the CFG pile can be accurately measured with the help of the pile detection assembly. Since the pile pushing assembly and the pile detection assembly are respectively set on both sides of the pile fixing assembly, the pushing cylinder of the pile pushing assembly drives the pushing push rod to extend and retract, so that the push plate can push the pile fixing assembly and the CFG pile closer to the detection probe of the pile detection assembly. Thus, the bearing capacity of the CFG pile can be measured by the bearing capacity tester body and the detection probe of the pile detection assembly. The method of measuring the bearing capacity of the CFG pile is simple and easy to implement.

[0019] The beneficial effects are as follows: 1. This utility model is equipped with a pile fixing component. At the same time, both the fixed clamp and the movable clamp of the pile fixing component are provided with V-shaped clamping grooves. Then, the CFG pile can be quickly centered and clamped by the movable clamp of the pile fixing component approaching the fixed clamp. The centering and clamping method of the CFG pile is simple and easy to implement, avoiding the situation of detection position displacement of the CFG pile during the detection process, which helps to avoid the occurrence of detection errors.

[0020] 2. By turning the adjusting stud in both directions, the movable clamp can be moved closer to or further away from the fixed clamp, thereby achieving the clamping and loosening of the CFG pile. The operation of clamping and loosening the CFG pile is simple and easy to implement. It is convenient to quickly center and clamp the CFG pile for testing, and it is also convenient to loosen and remove the CFG pile after the testing is completed.

[0021] 3. The lower part of the pile fixing assembly is equipped with a push guide assembly with lifting and adjusting function. By sliding the guide seat of the push guide assembly laterally along the guide groove, the CFG pile can be pushed and guided during the testing process to avoid the CFG pile from tilting during the testing process. At the same time, by extending and retracting the lifting push rod of the lifting cylinder, the position and height of the pile fixing assembly and the CFG pile can be adjusted, so as to make it easy to adjust the CFG pile to be concentric with the detection probe of the pile testing assembly, thereby ensuring that the bearing capacity of the CFG pile can be accurately determined with the help of the pile testing assembly.

[0022] 4. A pile pushing component and a pile detection component are respectively installed on both sides of the pile fixing component. Then, by driving the push cylinder of the pile pushing component to extend and retract the push rod, the push plate can push the pile fixing component and the CFG pile closer to the detection probe of the top-pressure pile detection component. Thus, the bearing capacity of the CFG pile can be measured by the bearing capacity tester body and detection probe of the pile detection component. The method of measuring the bearing capacity of the CFG pile is simple and easy to implement. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] See Figures 1-6As shown, this utility model provides a CFG pile quality control material bearing capacity testing device, including a base 3. A sliding guide component 4 with lifting and adjusting function is assembled in the middle of the top surface of the base 3, and the guiding direction of the sliding guide component 4 is set horizontally in the transverse direction. Specifically, the sliding guide component 4 includes a fixing plate 401, a guide seat 403, and a lifting cylinder 404. The fixing plate 401 is horizontally fixed in the middle of the top surface of the base 3, and a guide groove 402 is opened in the transverse direction on the top surface of the fixing plate 401. The guide seat 403 is placed in the guide groove 402 in a transverse sliding fit, and the lifting cylinder is vertically fixed on the top surface of the guide seat 403. 404, the lifting cylinder 404 has a vertically arranged lifting push rod 405 at the top, and the top end is fixed with a pile fixing assembly 1. The purpose of this arrangement is to guide the CFG pile during the detection process by pushing the guide seat 403 of the guide assembly 4 to slide laterally along the guide groove 402, so as to avoid the CFG pile from tilting during the detection process. At the same time, by extending and retracting the lifting push rod 405 of the lifting cylinder 404, the pile fixing assembly 1 and the CFG pile can be adjusted in position and height, so as to make it easier to adjust the CFG pile to be concentric with the detection probe 502 of the pile detection assembly 5.

[0034] See Figures 1-3 As shown, the top assembly of the pushing guide component 4 is equipped with a pile fixing component 1 for centering and clamping the CFG pile. Specifically, the pile fixing component 1 includes a fixed clamp 105, a movable clamp 103, and a U-shaped bracket 101. The top of the lifting push rod 405 is horizontally fixed with the fixed clamp 105. The movable clamp 103 is suspended parallel above the fixed clamp 105, and the two are vertically aligned. At the same time, the end faces of the movable clamp 103 and the fixed clamp 105 are horizontally provided with clamping grooves 104. The front and rear end faces of the fixed clamp 105 are horizontally extended and fixed with mounting plates 102. The U-shaped bracket 101 is inverted and fixed between the mounting plates 102 at the front and rear positions. The top horizontal part of the U-shaped bracket 101 is vertically threaded through the mounting plates 102. An adjusting stud 109 is inserted and installed. The bottom end of the adjusting stud 109 is coaxially rotatably connected to a bearing seat 1011, and the bearing seat 1011 is fixed in the middle of the top surface of the movable clamp 103. The clamping grooves 104 are all through grooves in the horizontal direction, and all clamping grooves 104 are V-shaped grooves. The reason for this setting is that, firstly, by moving the movable clamp 103 of the pile fixing assembly 1 close to the fixed clamp 105, the CFG pile can be quickly centered and clamped. The centering and clamping method of the CFG pile is simple and easy to implement. At the same time, by turning the adjusting stud 109 forward and reverse, the movable clamp 103 can be moved closer to or away from the fixed clamp 105, thereby realizing the clamping and loosening of the CFG pile. The operation of clamping and loosening the CFG pile is simple and easy to implement.

[0035] See Figures 1-3As shown, a pile pushing assembly 2 and a pile detection assembly 5 are respectively assembled on both sides of the top surface of the base 3. The pile pushing assembly 2 and the pile detection assembly 5 are located on both sides of the pile fixing assembly 1, and are used to test the bearing capacity of the CFG pile clamped in the pile fixing assembly 1. Specifically, the pile pushing assembly 2 includes a side seat 202 and a pushing cylinder 203. The side seat 202 is vertically fixed on one side of the top surface of the base 3 along the longitudinal direction. The pushing cylinder 203 is horizontally fixed on the upper outer side of the side seat 202. The push rod 204 of the pushing cylinder 203 passes through the inner side of the side seat 202 in a horizontal sliding fit. At the same time, a push plate 201 is vertically fixed on the end of the push rod 204 near the pile fixing assembly 1 along the longitudinal direction. The pile testing assembly 5 includes a testing support 503 and a bearing capacity testing instrument body 501. The testing support 503 is vertically fixed along the longitudinal direction on the other side of the top surface of the base 3. The bearing capacity testing instrument body 501 is embedded and fixed on the inner side of the testing support 503 near the pile fixing assembly 1. A testing probe 502 with its axis arranged laterally is disposed on the side of the bearing capacity testing instrument body 501. Simultaneously, the axis of the testing probe 502 and the lowest edge of the clamping groove 104 are located on the same horizontal and vertical plane. An instrument for adjusting the bearing capacity testing instrument body 501 is mounted on the front of the testing support 503. The control panel 504 is electrically connected to the bearing capacity testing instrument body 501. The purpose of this setting is that, by driving the push cylinder 203 of the pile body pushing assembly 2 to extend and retract the push rod 204, the push plate 201 can push the pile body fixing assembly 1 and the CFG pile body closer to the detection probe 502 of the top-pressure pile body detection assembly 5. Thus, the bearing capacity of the CFG pile body can be measured by the bearing capacity testing instrument body 501 and the detection probe 502 of the pile body detection assembly 5. The method of measuring the bearing capacity of the CFG pile body is simple and easy to implement.

[0036] See Figures 1-6 As shown, the following optimizations were made to the pushing guide component 4 and the pile fixing component 1. Specifically, the two ends of the fixing plate 401 are close to the pile pushing component 2 and the pile detection component 5, respectively. The guide groove 402 is either a dovetail groove or an I-shaped groove. This design ensures that the guide groove 402 has a design length that meets the usage requirements in the lateral direction, and that the guide seat 403 can only slide laterally along the guide groove 402 and cannot be dislodged from other directions. Further optionally, the base 3 has a connecting plate 301 that is flatly extended and fixed on both sides for fixing in the setting position. Preferably, the front and rear corners of the connecting plate 301 are provided with through holes so that the base 3 can be firmly fixed in the setting position by inserting bolts through the front and rear corners of the connecting plate 301.

[0037] See Figures 1-6As shown, a handwheel 106 for easy gripping is coaxially mounted on the top of each adjusting stud 109. A locking nut 1010 is coaxially engaged on the top surface of the horizontal part of the adjusting stud 109 extending out of the U-shaped bracket 101. This arrangement facilitates the rotation of the adjusting stud 109 by applying force through the handwheel 106, and also prevents the adjusting stud 109 from loosening naturally by pressing the locking nut 1010 against the top surface of the U-shaped bracket 101 after the adjusting stud 109 has been rotated and adjusted. Alternatively, the top of the U-shaped bracket 101 is provided with guide holes 108 at positions before and after the adjusting stud 109. Guide rods 107 are vertically and coaxially inserted into the guide holes 108 in a sliding fit, and the guide rods 107 are fixed to the top surface of the movable clamp 103. With this arrangement, when the adjusting stud 109 is rotated to drive the movable clamp 103 to rise and fall vertically, the guide rods 107 can slide vertically along the guide holes 108 to guide and correct the rising and falling process of the movable clamp 103, so as to avoid the adjusting stud 109 driving the movable clamp 103 to rotate horizontally and misalign.

[0038] Using the above structure, specifically for the testing of CFG piles, the pile fixing component 1 is provided. Both the fixed clamp 105 and the movable clamp 103 of the pile fixing component 1 have V-shaped clamping grooves 104. By moving the movable clamp 103 of the pile fixing component 1 close to the fixed clamp 105, the CFG pile can be quickly and accurately centered and clamped. This centering and clamping method for the CFG pile is simple and easy to implement, avoiding positional shifts during testing and helping to prevent testing errors. The discrepancy arises because the movable clamp 103 can move closer to or further away from the fixed clamp 105 by turning the adjusting stud 109 in both forward and reverse directions. This allows for the clamping and loosening of the CFG pile, making the clamping and loosening operation simple and easy to implement. It facilitates quick and easy centering and clamping of the CFG pile for testing, and also makes it easy to loosen and remove the CFG pile after testing. Furthermore, the lower part of the pile fixing assembly 1 is equipped with a push guide assembly 4 with lifting and adjusting function, which allows for the movement of the CFG pile through the push guide assembly 4. The guide seat 403 slides laterally along the guide groove 402, which can guide the CFG pile during the testing process and prevent the CFG pile from tilting during the testing. At the same time, the lifting push rod 405 of the lifting cylinder 404 can extend and retract to adjust the position and height of the pile fixing component 1 and the CFG pile, so as to make it easy to align the CFG pile with the detection probe 502 of the pile detection component 5. This ensures that the bearing capacity of the CFG pile can be accurately determined with the help of the pile detection component 5. The pile fixing component 1 is provided with a pile pushing component 2 and a pile detection component 5 on both sides. Then, by the pushing cylinder 203 of the pile pushing component 2 driving the push rod 204 to extend and retract, the push plate 201 can push the pile fixing component 1 and the CFG pile closer to the detection probe 502 of the top-pressing pile detection component 5. Thus, the bearing capacity of the CFG pile can be measured by the bearing capacity tester body 501 and the detection probe 502 of the pile detection component 5. The method of measuring the bearing capacity of the CFG pile is simple and easy to implement.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
