Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and particularly to a pile foundation detection device for bridge construction. Background Art

[0002] A deep foundation composed of a pile and a pile cap (abbreviated as the cap) connecting the top of the pile, or a single-pile foundation connecting a column and a pile foundation, is abbreviated as a pile foundation. As an indispensable load-bearing part in the construction field, the performance of the pile foundation is crucial. Therefore, a series of tests are often required for the pile foundation after pile formation, and the detection of the surface hardness of the pile foundation is particularly important.

[0003] At present, there are various pile foundation detection methods, but existing detection devices often have some deficiencies. For example, the detection accuracy is not high enough, the operation is complex, and the adaptability to different types of pile foundations is poor, making it difficult to meet the increasingly strict requirements for bridge construction quality. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides a pile foundation detection device for bridge construction, aiming to improve the accuracy and efficiency of pile foundation detection, and at the same time enhance the adaptability to different types of pile foundations.

[0006] (II) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A pile foundation detection device for bridge construction includes support side plates. There are two support side plates, and the bottoms of the two support side plates are fixedly connected to the same support bottom ring. The tops of the two support side plates are fixedly connected to the same support top ring. The middles of the two support side plates are fixedly connected to the same support middle ring. The middles of the support bottom ring, the support middle ring, and the support top ring are fixedly connected to the same support middle column. Two first threaded sleeves are fixedly connected to the inside of each support side plate. A first threaded rod is threadedly connected to the inside of each first threaded sleeve. The inner ends of the first threaded rods are fixedly connected to rotating balls, and the outer side walls of the rotating balls are rotatably connected to rotating seats.

[0008] A detection inner groove is provided inside the support middle column. A rotating frame is rotatably connected to the inside of the detection inner groove. One end of the rotating frame away from the support side plate is fixedly connected to a punching block. A connecting rope is fixedly connected to the top of the detection inner groove. The bottom of the connecting rope is fixedly connected to a detection head. Second threaded sleeves are fixedly connected to the top and bottom of the support middle column. A second threaded rod is threadedly connected to the inside of each second threaded sleeve. One end of the second threaded rod close to the support side plate is rotatably connected to a fixed seat.

[0009] Preferably, the supporting bottom ring, the supporting middle ring and the supporting top ring are arranged in a semi-circular ring shape. The supporting bottom ring, the supporting middle ring, the supporting top ring and the supporting side plates are made by an integral molding technique. The supporting bottom ring, the supporting middle ring and the supporting top ring are parallel to each other, and the supporting side plates are smoothly transitioned with the supporting bottom ring, the supporting middle ring or the supporting top ring.

[0010] Preferably, the supporting side plates and the supporting bottom ring, the supporting middle ring or the supporting top ring all enclose a semi-straight notch shape, and the shapes and sizes of the supporting bottom ring, the supporting middle ring and the supporting top ring are the same.

[0011] Preferably, a counterweight inner groove is arranged inside the punching block, and a number of counterweight blocks are filled inside the counterweight inner groove. The upper side wall of the punching block is threadedly connected with a matching cover, and a handrail is fixedly connected to the top of the matching cover. The punching block can be pulled to rotate upward through the handrail.

[0012] Preferably, a punch is fixedly connected to the bottom of the punching block. The punch is matched with the detection head. The right side of the detection head is conical, which is convenient for impacting the bridge pile foundation. The center of the punching block is aligned with the center of the detection head, and the punching block can impact the detection head through the punch.

[0013] Preferably, a number of universal wheels are installed on the lower side walls of the supporting side plates and the supporting bottom ring. A braking structure is arranged inside the universal wheels for braking the wheels in the universal wheels. A handle is fixedly connected to the upper side wall of the supporting top ring, and the device can be conveniently pushed to move through the handle.

[0014] Preferably, a first turntable is fixedly connected to the outer end of each first threaded rod. The first threaded rod can be driven to rotate through the first turntable. A second turntable is fixedly connected to the outer end of the second threaded rod. The second threaded rod can be driven to rotate through the second turntable.

[0015] Preferably, anti-slip patterns are arranged on the outer side walls of the rotating seat and the fixed seat, which can effectively improve the fixing effect between the device and the bridge pile foundation.

[0016] Working principle: When the pile foundation detection device for bridge construction of the present invention is in use, first, the device is moved to the position of the pile foundation to be detected through the universal wheels, and then the universal wheels are braked by using the braking structure to ensure the stability of the device. Then, the first threaded rod is rotated through the first turntable to make the rotating seat closely fit with the surface of the pile foundation, realizing the preliminary fixation of the device. Subsequently, the second threaded rod is rotated through the second turntable to make the fixed seat further contact with the surface of the pile foundation, enhancing the fixing effect of the device and making the detection inner groove aligned with the center of the pile foundation.

[0017] During the detection process, the punching block is rotated upward by pulling the armrest, and then the armrest is released. Under the action of gravity, the punching block impacts the detection head through the punch. The detection head transmits the impact force to the inside of the pile foundation. By detecting the propagation of stress waves inside the pile foundation, the integrity of the pile foundation can be judged. At the same time, by adjusting the number and position of the counterweight blocks, the weight and impact force of the punching block can be changed to meet the detection requirements of different types of pile foundations.

[0018] (III) Beneficial effects

[0019] The present invention provides a pile foundation detection device for bridge construction, which has the following beneficial effects:

[0020] 1. The overall structure of the device is designed simply, and the connection and operation methods between components are simple and clear. Construction workers can quickly get started, improving the detection efficiency. Through the cooperation of the punching block and the detection head, a stable impact force can be generated. The detection head transmits the impact force to the inside of the pile foundation. By detecting the propagation of stress waves, the integrity of the pile foundation can be accurately judged, improving the detection accuracy.

[0021] 2. By adjusting the number and position of the counterweight blocks, the weight and impact force of the punching block can be changed, enabling the device to meet the detection requirements of different types of pile foundations, enhancing the versatility and adaptability of the device. Universal wheels are installed at the bottom of the device, facilitating movement to different detection positions. At the same time, through the cooperation of the rotating seat and the fixed seat, the device can be quickly fixed to ensure the stability of the detection process. BRIEF DESCRIPTION OF THE DRAWINGS
