Description

Technical Field

[0001] This application relates to the field of on-site sampling equipment, and in particular to an adjustable combined core sampling and fixing device for dry-operation bored piles. Background Technology

[0002] Core sampling is a common method for testing the quality of pile foundations. It involves extracting rock cores from the piles and examining their physical and mechanical properties to determine the quality of the pile foundation. Properly executed core sampling improves the accuracy and reliability of the test results, ensuring project quality and safety.

[0003] Existing pile foundation coring techniques include manual drilling and rig coring. Construction workers first go down into the foundation pit and drill a hole at the top of the pile for positioning. The construction workers drill a hole at the top of the pile, and then the rig enters the foundation pit, inserts the drill rod into the hole and continues drilling, thus completing the coring work.

[0004] The aforementioned technical solutions have the following drawbacks: when the drilling rig is drilling, there is a lack of support around the drill rod, and the drill rod is prone to swinging when it falls and feeds, resulting in inaccurate positioning and difficulty in drilling into the concrete surface. Utility Model Content

[0005] To reduce the likelihood of drill rod swaying during feed, this application provides an adjustable combined core-pulling detection and fixing device for dry-operation bored piles.

[0006] The adjustable combined core-pulling detection and fixing device for dry-operation bored cast-in-place piles provided in this application adopts the following technical solution:

[0007] An adjustable combined core-pulling detection and fixing device for dry-drilled cast-in-place piles includes multiple fixing sleeves, multiple rod frames, and multiple clamps. The fixing sleeves are used to be fitted over the drill rods, and the clamps are fitted over the fixing sleeves. Each rod frame is equipped with multiple clamps, and each rod frame is connected to two fixing sleeves through clamps. Adjacent rod frames are set at an angle to each other.

[0008] By adopting the above technical solution, a fixed sleeve is installed outside the drill rod and fixed in the pit by the rod frame. When the drill rod is fed downward, the drill rod is inside the fixed sleeve, thereby reducing the probability of horizontal swing of the drill rod. By setting two clamps on the rod frame and connecting the two clamps to the two fixed sleeves respectively, the multiple fixed sleeves are fixed at a fixed distance, reducing the probability of fixed sleeve swing and achieving the effect of reducing drill rod shaking.

[0009] Optionally, the end of the pole frame is provided with a threaded tube, and the end of the pole frame is threaded, with the threaded tube being threadedly connected to the pole frame.

[0010] By adopting the above technical solution, a threaded tube is installed at the end of the pole frame. The user can tighten the threaded tube so that the end of the threaded tube abuts against the inner wall of the pit, thus fixing the pole frame in pits of different sizes.

[0011] Optionally, the clamp is detachably connected to the rod frame.

[0012] By adopting the above technical solution, and by making the clamp and the pole frame detachably connected, users can set clamps of different shapes on the pole frame, so that the clamps can hold fixed sleeves of different sizes, which is convenient for use.

[0013] Optionally, the clamp includes two connecting rings and a semi-circular arc member. The semi-circular arc member is sleeved outside the fixed sleeve and abuts against the fixed sleeve. The two connecting rings are respectively fixed at both ends of the semi-circular arc member, and the rod passes through the two connecting rings.

[0014] By adopting the above technical solution, a connecting ring is set on the semi-circular arc part, allowing the rod frame to be inserted into the connecting ring, thereby enabling the clamp to rotate relative to the rod frame, facilitating the installation of the clamp on the fixed sleeve. The clamp can slide on the rod frame, further facilitating the installation of the fixed sleeve.

[0015] Optionally, the clamp is provided with a collar, which is a circular ring structure, parallel to the semi-circular arc part, and a support rod is provided on the collar, with one end of the support rod fixed on the collar and the other end fixed on the semi-circular arc part.

[0016] By adopting the above technical solution, and by setting a collar on the clamp, when the clamp is fitted onto the fixed sleeve, the semi-circular part and the collar can be simultaneously clamped onto the fixed sleeve, thereby reducing the probability of the fixed sleeve shifting position during sampling.

[0017] Optionally, the clamp is provided with a hook, and a hanging ring is fixed on the outer wall of the fixing sleeve, with the hook engaging with the hanging ring.

[0018] By adopting the above technical solution, by setting hooks on the clamps and hanging rings on the fixing sleeves, the hooks can be hung on the hanging rings, thereby ensuring a tight connection between the fixing sleeves and the clamps, making it convenient for users to hoist and fix the device.

[0019] Optionally, one end of the hook is rotatably connected to the semi-circular arc component, and the other end is engaged with the hanging ring.

[0020] By adopting the above technical solution, the hook is rotated and connected to the semi-circular arc, making it convenient for users to connect or remove the fixing sleeve to the clamp.

[0021] Optionally, the clamp is equipped with multiple position sensors, which are used to detect the spacing between adjacent clamps.

[0022] By adopting the above technical solution, and by setting position sensors on the clamps so that the position sensors are parallel to the length direction of the rod frame, the position sensors can be aligned with adjacent position sensors. By monitoring the distance between two adjacent position sensors, construction personnel can determine whether the fixed sleeve has shifted position, thus facilitating the determination of the work quality of core sampling.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By installing a fixed sleeve outside the drill pipe, the fixed sleeve is fixed in the pit by the rod frame. When the drill pipe is fed downward, the drill pipe is inside the fixed sleeve, thereby reducing the probability of horizontal swing of the drill pipe. By installing two clamps on the rod frame, the two clamps are connected to two fixed sleeves respectively, thereby fixing the distance between multiple fixed sleeves and reducing the probability of fixed sleeve swing, thus achieving the effect of reducing drill pipe shaking.

[0025] 2. By installing threaded pipes at the ends of the poles, the users can tighten the threaded pipes to make the ends of the threaded pipes abut against the inner wall of the pit, thus allowing the poles to be fixed in pits of different sizes.

[0026] 3. By installing position sensors on the clamps and aligning them parallel to the length of the rod, the position sensors can be aligned with adjacent position sensors. By monitoring the distance between two adjacent position sensors, construction personnel can determine whether the fixed casing has shifted position, thus facilitating the assessment of the core sampling work quality.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses an adjustable combined core-pulling detection and fixing device for dry-operation bored cast-in-place piles, referring to... Figure 1 and Figure 2 The system includes multiple fixed sleeves 1, multiple rod frames 2, and multiple clamps 3. At least three fixed sleeves 1 are provided, which are used to fit over the drill rod. Each rod frame 2 has two clamps 3, and each clamp 3 is fitted onto one fixed sleeve 1. Multiple clamps 3 are fitted onto the same fixed sleeve 1. The multiple rod frames 2 are arranged at an angle to each other, and are used to horizontally engage with the inner wall of the pit. When core sampling and testing of bored piles are performed, the construction personnel hoist the fixing device into the pit, so that the rod frames 2 are horizontally positioned and abut against the inner wall of the pit. This allows the fixed sleeves 1 to remain vertical. When the drill rod is inserted into the fixed sleeve 1 and drilled down for sampling, the probability of the drill rod swinging horizontally is reduced, thereby improving the efficiency of drilling and sampling and decreasing the probability of drill rod breakage.

[0034] Reference Figure 2 The pole frame 2 has threads at both ends, and a threaded pipe 4 is detachably connected to the end of the pole frame 2. The threaded pipe 4 is used for threaded connection to the end of the pole frame 2. When the fixing device is hoisted into the foundation pit, the construction workers can tighten the threaded pipe 4 so that the end of the threaded pipe 4 abuts against the inner wall of the foundation pit, thereby fixing the fixing device in the foundation pit.

[0035] Reference Figure 3 The clamp 3 includes two connecting rings 31 and a semi-circular arc member 32. The semi-circular arc member 32 has a semi-circular arc structure and is sleeved on the outside of the fixed sleeve 1. The two connecting rings 31 are respectively connected to the two ends of the semi-circular arc member 32. The rod frame 2 can pass through the connecting rings 31, so that the clamp 3 is rotatably connected to the rod frame 2. The clamp 3 can slide on the rod frame 2, thereby adjusting the spacing of the fixed sleeve 1.

[0036] Reference Figure 3 In other embodiments, the clamp 3 is provided with a collar 33, which is a circular ring structure. The collar 33 is parallel to the semi-circular arc member 32. Multiple support rods 331 are provided on the collar 33, with one end of each support rod fixed to the collar 33 and the other end fixed to the semi-circular arc member 32. The radius of the semi-circular arc member 32 is the same as the radius of the collar 33. When the fixing sleeve 1 is inserted into the clamp 3, both the semi-circular arc member 32 and the collar 33 are fitted over the fixing sleeve 1, thereby limiting the position of the fixing sleeve 1 and further reducing the probability of the fixing sleeve 1 tilting during drilling.

[0037] Reference Figure 4A hook 34 is provided on the semi-circular arc component 32. The hook 34 is used to hang on the fixed sleeve 1, thereby reducing the chance of the clamp 3 sliding vertically on the fixed sleeve 1 and making it easier for the user to hoist the fixing device into the foundation pit. A hanging ring 11 is provided on the outer wall of the fixed sleeve 1. The hanging ring 11 is used to engage with the end of the hook 34. One end of the hook 34 is rotatably connected to the semi-circular arc component 32, and the other end is detachably connected to the hanging ring 11. The fixed sleeve 1 is connected to the clamp 3 through the hook 34. The clamp 3 is connected to the pole 2, which facilitates the hoisting by the construction personnel.

[0038] Reference Figure 3 Multiple position sensors 5 are installed on the clamp 3, and the position sensors 5 are spaced apart along the circumference of the semi-circular part 32. The position sensors 5 are used to face the position sensors 5 of other clamps 3. The position sensors 5 can be infrared distance sensors. The position sensors 5 on adjacent clamps 3 measure the distance between the two position sensors 5 and output an electrical signal. By monitoring the signals of the position sensors 5, the construction personnel can monitor whether the position of the fixed sleeve 1 has shifted, thereby improving the construction quality.

[0039] The implementation principle of this application embodiment is as follows: by fitting a clamp 3 on the fixed sleeve 1, the clamp 3 is installed on the rod frame 2, so that the fixed sleeve 1 has the effect of limiting the drill rod. When the rod frame 2 is stuck in the pit, the probability of horizontal shaking of the drill rod can be reduced, so that the drill rod can fall vertically and the sample can be taken out in the pit. By setting a threaded tube 4 at the end of the rod frame 2, the construction personnel can rotate the threaded tube 4 to make the threaded tube 4 slide along the length direction of the rod frame 2, so that the end of the threaded tube 4 can abut against the inner wall of the pit, and the fixing device can be installed in pits of different sizes.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
