Description

Technical Field

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

[0002] The pile foundation of a bridge is composed of many piles driven or sunk into the soil and a cap connected to the top of the piles. Cast-in-place piles are a type of bridge pile foundation. First, a pile hole is made in the soil by hand or machinery, and then the pile body steel cage is placed in the pile hole, and concrete is poured into the hole to form a pile foundation.

[0003] The bridge pile foundation is the basic part of the bridge. The quality of the pile foundation is directly related to the safety and durability of the bridge. If there are defects in the pile foundation, it may cause uneven settlement, tilting or even collapse of the bridge. Therefore, it is necessary to ensure the quality of the pile foundation through testing. The usual detection method for bridge pile foundation is to use ultrasonic feedback and use sensors to judge the integrity of the pile body according to the characteristics of the signal. If it is found that the pile foundation itself may have defects or there are doubts about the test results, the coring method can be used as a further verification method.

[0004] However, the coring method usually uses a desktop water drill to drill and coring. Before the desktop water drill is used for drilling and coring, it is first necessary to set an anchor point on the bridge pile foundation to fix the desktop water drill, and then fix the desktop water drill on the anchor point to start the coring work. The operation steps of drilling and coring in this way are complicated when installing the equipment, and when sampling is performed at multiple positions of a pile foundation, multiple fixations are required, which affects the sampling efficiency and also causes more damage to the bridge pile foundation.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] like Figure 1 As shown, a bridge pile foundation detection device includes a track mechanism 1 arranged on the bridge pile foundation, and an electric slide 2 is slidably connected to the track mechanism 1. The detection device also includes an adjustment mechanism 3 for adjusting the sampling position, and the adjustment mechanism 3 is arranged on the electric slide 2. The detection device also includes a sampling mechanism 4 jointly arranged on the electric slide 2 and the adjustment mechanism 3.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the track mechanism 1 includes an arcuate base 11 and a straight base 12. The two arcuate bases 11 are spliced ​​together by the straight base 12. The outer sides of the arcuate base 11 and the straight base 12 are fixedly connected with sliding tracks 13. A limiting member 14 is provided on the arcuate base 11. Four arcuate bases 11 and multiple straight bases 12 can be spliced ​​into an annular base suitable for different types of bridge pile foundations.

[0038] like Figure 2 and Figure 5As shown, the two end surfaces of the arc base 11 are respectively provided with slots and fixedly connected with pins, and the two end surfaces of the straight base 12 are also respectively provided with slots and fixedly connected with pins. The size of the slot on the arc base 11 is adapted to the size of the pin on the straight base 12 and they are snap-fitted together. When the pin and the slot are snap-fitted together, the slot is placed above the pin and kept in a position that overlaps with the pin in the vertical direction. Then the slot is moved downward and the pin is snap-fitted inside the slot. At this time, the pin and the slot cooperate to perform circumferential limiting connection on the arc base 11 and the straight base 12.

[0039] In specific use, when sampling a bridge pile foundation in the shape of a rounded rectangle, first, four arc bases 11 are evenly distributed in the circumferential direction, and the same number of straight bases 12 are clamped between the two arc bases 11 opposite to each other in the front and back, and the same number of straight bases 12 are clamped between the two arc bases 11 opposite to each other in the left and right, and the number of straight bases 12 clamped between the two arc bases 11 opposite to each other in the front and back is different from the number of straight bases 12 clamped between the two arc bases 11 opposite to each other in the left and right, and the straight bases 12 are clamped between the opposite surfaces of the two arc bases 11 through the pins and grooves on the adjacent surfaces of the arc bases 11, and multiple arc bases 11 and multiple straight bases 12 are assembled into an annular base suitable for the bridge pile foundation in the shape of a rounded rectangle, and at the same time, the sliding tracks 13 on all the arc bases 11 and the straight bases 12 are jointly enclosed to form an annular track suitable for the bridge pile foundation in the shape of a rounded rectangle (such as Figure 4 shown).

[0040] Then install the electric slide 2 on the sliding rail 13. After the assembly is completed, the annular base is mounted on the bridge pile foundation from the top through the limiting piece 14 and the lifting ring on the straight base 12 through the external lifting equipment, and then moved downward to a suitable position. Then, the annular base is fixed on the bridge pile foundation through the limiting piece 14 on the arc base 11, and the lifting of the arc base 11 and the straight base 12 by the external lifting equipment is cancelled.

[0041] like Figure 1 , Figure 5 and Figure 6As shown, the limiting member 14 includes a first hydraulic telescopic cylinder 141 fixedly connected to the upper surface of the arc-shaped base 11 through a connecting sleeve, the telescopic end of the first hydraulic telescopic cylinder 141 is hinged with a positioning plate 142, and a plurality of evenly distributed auxiliary pins 143 are slidably connected to a surface of the positioning plate 142 away from the first hydraulic telescopic cylinder 141, and the auxiliary pins 143 penetrate into the interior of the positioning plate 142, and a connecting spring (not shown in the figure) is arranged between the end of the auxiliary pin 143 close to the positioning plate 142 and the positioning plate 142, and a sliding adjustment sleeve 145 is fixedly connected to the bottom end of the positioning plate 142, and a second hydraulic telescopic cylinder 144 is hinged on the sliding adjustment sleeve 145, and the end of the second hydraulic telescopic cylinder 144 away from the sliding adjustment sleeve 145 is hinged to the lower surface of the track mechanism 1, and a lifting ring is arranged at the center position of the mounting sleeve on the first hydraulic telescopic cylinder 141 and the upper surface of the linear base 12.

[0042] During specific use, when the annular base is fixed on the bridge pile foundation by the limiter 14, when the annular base moves to the specified position, the first hydraulic telescopic cylinder 141 is extended to push the positioning plate 142 to move in the direction close to the bridge pile foundation. At this time, the auxiliary nail 143 on the positioning plate 142 is in contact with the surface of the bridge pile foundation. As the positioning plate 142 is continuously pushed, the auxiliary nail 143 is subjected to the resistance of the bridge pile foundation and slides toward the inside of the positioning plate 142. At the same time, the connecting spring is compressed. Under the action of the elastic force of the connecting spring itself, the auxiliary nail 143 is pressed against the surface of the bridge pile foundation. By setting up a plurality of evenly distributed auxiliary pins 143, the contact area between the positioning plate 142 and the arc surface of the bridge pile foundation can be increased, and the friction between the positioning plate 142 and the bridge pile foundation can be improved. When the first hydraulic telescopic cylinder 141 pushes the positioning plate 142 against the bridge pile foundation, the second hydraulic telescopic cylinder 144 is extended to push the bottom end of the positioning plate 142 against the bridge pile foundation simultaneously. At this time, the four corners of the annular base formed by the arc base 11 and the straight base 12 are subjected to a force in the direction away from the bridge pile foundation, and the closed loop of the annular base is cooperated to fix the annular base firmly on the bridge pile foundation.

[0043] like Figure 1 and Figure 7 As shown, the adjustment mechanism 3 includes a first drive motor 34 embedded in the center of the upper surface of the electric slide 2, and a screw rod 32 is fixedly connected to the output shaft of the first drive motor 34. The upper surface of the electric slide 2 slides up and down and is penetrated by two groups of left-right symmetrical limit slides 33. The bottom ends of the two groups of limit slides 33 penetrate to the lower surface of the electric slide 2 and are fixedly connected to a fixed block 35. The top ends of the two groups of limit slides 33 are fixedly connected to a limit slide 31. The screw rod 32 penetrates the limit slide 31 up and down and is threadedly connected to the limit slide 31.

[0044] During specific use, after the annular base is fixed, the electric slide 2 slides on the sliding track 13 to drive the sampling mechanism 4 to move above the sampling position, and then the first drive motor 34 drives the screw rod 32 to rotate. At this time, the screw rod 32 rotates on the limiting slide 31, and the circumferential direction of the limiting slide 31 is limited by four limiting slides 33. The limiting slide 31 pushes the limiting slide 33 to move downward on the electric slide 2, and the limiting slide 33 pushes the fixed block 35 to move downward. After the fixed block 35 drives the sampling mechanism 4 to move downward to the sampling position below the water surface, the rotation of the first drive motor 34 is stopped, and then sampling is started through the sampling mechanism 4.

[0045] like Figure 1 and Figure 8 As shown, the sampling mechanism 4 includes two front-to-back symmetrical supporting frames 44 fixedly connected to the upper surface of the electric slide 2, the top ends of the two supporting frames 44 are slidably connected to a connecting slide 45 along the front-to-back direction, a sampling piece 42 is commonly provided on the supporting frame 41 and the connecting slide 45, and an adjusting piece 43 is commonly provided on the supporting frame 41, the sampling piece 42 and the connecting slide 45.

[0046] like Figure 8 , Fig. 9 and Fig.10 As shown, the sampling member 42 includes two left-right symmetrical connecting sliders 422 slidably connected to the support frame 41 along the front-back direction, a first transmission box 421 is fixedly connected between the opposite surfaces of the two connecting sliders 422, a first spline shaft 424 is rotatably connected to the upper surface of the first transmission box 421, a first spline shaft 424 is slidably connected to the upper surface of the first spline shaft 424 along the up-down direction, a second drive motor 426 is fixedly installed on the upper surface of the connecting slide 45, and the output shaft of the second drive motor 426 passes through the connecting slide 45. The lower surface of the connecting plate 45 is fixedly connected to the top of the first spline shaft cylinder 423, the rear surface of the first transmission box 421 is rotatably connected to the drill bit 425, the front and rear surfaces of the fixed block 35 are provided with through holes adapted to the drill bit 425, the rear end of the drill bit 425 passes through the through hole on the fixed block 35 and is rotatably connected to the fixed block 35 and slidingly connected along the front and rear directions, the first spline shaft 424 and the end of the drill bit 425 close to the first transmission box 421 are both penetrated into the interior of the first transmission box 421, and are connected through a bevel gear transmission (such as Fig.11 shown).

[0047] like Figure 8 , Fig. 9 and Fig.10As shown, the adjusting member 43 includes a second transmission box 433 fixedly connected to the upper surface of the left connecting slider 422, the left side of the second transmission box 433 is rotatably connected to a circular gear 434, the left side of the support frame 41 is fixedly connected to a rack 435, the circular gear 434 meshes with the rack 435, the upper surface of the second transmission box 433 is rotatably connected to a second spline shaft 431, the outer surface of the second spline shaft 431 is slidably connected to a second spline shaft cylinder 432 in the up and down directions, and the left side of the connecting slide 45 is fixedly connected to L The third drive motor 437 is fixedly installed on the top of the vertical section of the L-shaped connecting plate 436. The top of the second spline shaft cylinder 432 penetrates to the upper surface of the horizontal section of the L-shaped connecting plate 436 in the up-down direction and is fixedly connected to the bottom end of the output shaft of the third drive motor 437. The top of the second spline shaft cylinder 432 is provided with a rotating handle. The second spline shaft 431 and the end of the circular gear 434 close to the second transmission box 433 are both penetrated into the interior of the second transmission box 433 and are connected by a bevel gear transmission (such as Fig.12 shown).

[0048] During specific use, when the fixed block 35 drives the sampling mechanism 4 to move downward, the support frame 41 moves downward with the fixed block 35. In the process of the support frame 41 and the fixed block 35 driving the drill bit 425 to move to the sampling position, the first transmission box 421 and the second transmission box 433 move synchronously with the support frame 41, and at the same time drive the first spline shaft 424 to slide downward inside the first spline shaft cylinder 423, and the second spline shaft 431 to slide downward inside the second spline shaft cylinder 432. When the drill bit 425 moves to the sampling position, the second drive motor 426 rotates through the first spline shaft cylinder 423 to drive the first spline shaft 424 to slide in the first transmission box. The bottom end of the first transmission box 421 drives the drill bit 425 to rotate on the first transmission box 421 through a bevel gear transmission, and the sampling work starts. While the drill bit 425 rotates, the third drive motor 437 drives the second spline shaft 431 to rotate on the second transmission box 433 through the second spline shaft cylinder 432. The bottom end of the second spline shaft 431 drives the circular gear 434 to rotate on the second transmission box 433 through a bevel gear transmission. When the circular gear 434 rotates, the rack 435 drives the connecting slider 422 to slide backward on the support frame 41, pushing the drill bit 425 to drill holes on the bridge pile foundation for sampling.

[0049] When the drill bit 425 completes sampling, the second drive motor 426 stops driving the drill bit 425 to rotate, and the third drive motor 437 starts to rotate in the opposite direction, driving the circular gear 434 to rotate in the opposite direction on the rack 435, so that the drill bit 425 moves in the opposite direction away from the bridge pile foundation, and the drill bit 425 is separated from the bridge pile foundation. When multiple sampling is required on the bridge pile foundation, the staff is transported to the sampling position by the external lifting platform equipment to take out and save the sample inside the drill bit 425, and then repeat the above steps for the next sampling work When all the sampling is completed, first reconnect with the limit piece 14 and the lifting ring on the linear base 12 through the external lifting equipment, and then the first hydraulic telescopic cylinder 141 and the positioning plate 142 are contracted synchronously to cancel the thrust on the positioning plate 142. At this time, the positioning plate 142 gradually moves away from the bridge pile foundation, and the annular base is no longer subjected to thrust. The annular base is removed from the bridge pile foundation through the external lifting equipment, and the collected samples are independently stored and marked, and then sent to the laboratory for further verification of the suspected locations of the bridge pile foundation quality.

[0050] When only one sampling is required on a bridge pile foundation, first repeat the above steps of removing the annular base, remove the annular base from the bridge pile foundation, then take the sample out from the inside of the drill bit 425, and then store and mark the sample independently, and then send it to the laboratory for further verification of the suspected location of the bridge pile foundation quality.

[0051] It should be noted that when sampling is performed on a cylindrical bridge pile foundation, first, four arc-shaped bases 11 are evenly distributed in the circumferential direction. According to the size of the cylindrical bridge pile foundation, the same number of linear bases 12 are clamped between two adjacent arc-shaped bases 11. All the arc-shaped bases 11 and the linear bases 12 are surrounded by a ring-shaped base adapted to the cylindrical bridge pile foundation. The sliding tracks 13 on the arc-shaped bases 11 and the linear bases 12 are combined to form a ring-shaped track adapted to the cylindrical bridge pile foundation. Then, the above steps are repeated to perform sampling on the cylindrical bridge pile foundation (such as Fig.13 shown).

[0052] Working principle: In specific use, firstly, according to the shape of the bridge pile foundation, four arc-shaped bases 11 are evenly distributed in a circle, and a suitable number of straight-shaped bases 12 are matched to form a ring-shaped base around the bridge pile foundation. At the same time, the sliding tracks 13 on the arc-shaped base 11 and the straight-shaped base 12 are combined into a ring-shaped track, and the base is hoisted to the position of the bridge pile foundation at a certain distance from the water surface with external hoisting equipment, and the arc-shaped base 11 and the straight-shaped base 12 are fixed on the bridge pile foundation by the limiter 14, and then the sampling piece 42 is adjusted by sliding circumferentially on the sliding track 13 by the electric slide 2. The sampling piece 42 moves from the circumferential position on the bridge pile foundation to the sampling position. At this time, the sampling piece 42 is pushed downward into the water to the sampling position through the adjusting mechanism 3. Then the staff pushes the sampling piece 42 toward the direction close to the bridge pile foundation through the adjusting piece 43, and starts sampling on the bridge pile foundation. When the sampling is completed, the sampling piece 42 is pushed back to its original position through the adjusting piece 43. At the same time, the adjusting mechanism 3 drives the sampling piece 42 to move upward out of the water. After that, the staff removes the sample from the sampling piece 42 and sends the sample to the laboratory for testing, thereby completing further verification of the suspected position of the bridge pile foundation quality.
