Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sediment detection, in particular to a bored pile sediment detection device. Background Art
[0002] The sediment at the bottom of the bored pile is an important factor affecting the bearing capacity of the pile foundation. Excessively thick sediment will produce a "cushion" effect, thereby reducing the bearing capacity of the pile and increasing the settlement of the pile body. Studies have shown that when the sediment thickness increases and the strength decreases, the maximum loss of pile end resistance can reach more than 80%, and the thicker the sediment, the greater the loss of pile foundation bearing capacity. The thickness of the sediment at the bottom of the bored pile is an important indicator of the hole quality, and its control and measurement measures are one of the key measures to ensure the construction quality of bored piles and the bearing capacity of pile foundations.
[0003] At present, the sediment thickness is usually obtained by measuring ropes and the experience of supervisors and construction personnel; manual measurement is adopted, in which a measuring rope is held manually and a weight is used to drop the measuring rope into the borehole, and the sediment thickness is judged by observing the reading of the measuring rope.

[0025] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the positioning structure 2 also includes a slide groove 24, teeth 25 and a rubber sleeve 26. The slide groove 24 is arranged at the two ends of the side wall of the main rod 22 in a relative shape, the teeth 25 are fixed to the inner wall of one end of the slide groove 24, and the rubber sleeve 26 is fixed to the inside between the bottom end of the slide groove 24 and the empty groove; the positioning block 35 slides inside the slide groove 24, and one end of the measuring ruler 61 is fixed to the bottom surface of the positioning block 35, and the extended end of the measuring ruler 61 slides inside the slide groove 24 following the movement of the positioning block 35, and the rubber sleeve 26 is clamped on the side wall of the measuring ruler 61 at the bottom end of the slide groove 24.
[0026] When the limit plate 31 slides up and down on the main rod 22, the positioning block 35 can pull the measuring ruler 61 to slide and extend inside the slide groove 24, so that the reel 62 compresses the mainspring 63 to store force, so that the measuring ruler 61 extends or contracts as the limit plate 31 slides up and down. The rubber sleeve 26 can clean the impurities adsorbed on the side wall of the measuring ruler 61 to ensure that the measuring ruler 61 is clean.
[0027] In the specific implementation process, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the card and structure 4 also includes a gear 46, a spring 47, a stopper 48 and a limiting groove 49, the gear 46 is rotatably connected to the side wall of the rotating shaft 44, the spring 47 is installed on the inner side wall of the gear 46, the stopper 48 is fixed to one end of the spring 47, and the limiting groove 49 is provided on the side walls at both ends of the shell 41; the shape of the fixing frame 43 is concave, and the rotating shaft 44 and the fixing frame 43 are fixedly connected, and the two ends of the rotating shaft 44 slide inside the limiting groove, and the depth of the concave shape of the fixing frame 43 is greater than the maximum radius of the gear 46; one end of the gear 46 is inside the sliding groove 24, and the gear 46 is meshed with the teeth 25, and the stopper 48 slides on the inner side wall of the gear 46, and the stopper 48 is stuck with the blocking tooth 45.
[0028] It is convenient to rotate the screw rod 42 so that it can rotate with the shell 41, and then pull or push the rotating shaft 44 to slide inside the limiting groove through the fixing frame 43, thereby driving the gear 46 to slide inside the shell 41, driving it to engage or disengage with the teeth 25. When engaged, the shell 41 can slide upward on the side wall of the main rod 22, and the gear 46 can rotate counterclockwise on the side wall of the rotating shaft 44, that is, the stop tooth 45 limits the stop block 48, so that the stop tooth 45 is stuck with the gear 46 and the teeth 25 to rotate clockwise. When the shell 41 moves upward to any position, it can be stuck on the side wall of the main rod 22 through the gear 46 and the teeth 25. When separated, the shell 41 can slide up and down on the side wall of the main rod 22 at will, and will not be stuck and positioned.
[0029] In the specific implementation process, Figure 1 and Figure 2 As shown, the length of the positioning rod 23 is equal to that of the main rod 22 , and the edge of the limiting plate 31 slides on the side wall of the positioning rod 23 through the sleeve 32 and the through groove 34 .
[0030] The limiting plate 31 can slide smoothly up and down on the side wall of the main rod 22 under the limitation of the positioning rod 23 , and the sleeve 32 can effectively prevent the sediment 5 from penetrating into the surface of the limiting plate 31 through the through groove 34 .
[0031] The working principle of the cast-in-place pile sediment detection device provided by the utility model is as follows:
[0032] When in use, firstly, by rotating the screw rod 42, the fixing frame 43 is driven to push the rotating shaft 44 to slide to one end, so that the gear 46 is meshed with the teeth 25, and then the probe rod 1 is inserted from the top of the pile pit 7 with its bottom end fixed to the fixing frame 43 and the device fixed to the bottom surface of the fixing frame 43. As the probe rod 1 goes deeper, the even-numbered limit plates 31 at the lowest end first contact the surface of the sediment 5 at the bottom end of the pile pit 7, and then a downward thrust is applied to the probe rod 1, driving the probe rod 1 to push the positioning frame 21 downward, so that the main rod 22 and the main rod 22 fixed to the bottom surface of the positioning frame 21 are moved downward. The positioning rod 23 is inserted into the interior of the sediment 5 until its bottom end contacts the bottom surface of the pile pit 7. When the main rod 22 and the positioning rod 23 are inserted downward into the interior of the sediment 5, the limiting plate 31 receives greater resistance from the sediment 5 due to its larger area, and thus floats on the surface of the sediment 5 and cannot move downward. As the main rod 22 and the positioning rod 23 pass through the limiting plate 31 through the through groove 34, the sleeve 32 and the branch pipe 33 can effectively prevent the sediment 5 from penetrating into the surface of the limiting plate 31 through the through groove 34, and the branch pipe 33 can also support the shell 41 on the side wall of the main rod 22 , so that the gear 46 rotates counterclockwise along the slide groove 24 under the meshing of the teeth 25. When one end of the stop block 48 contacts the stop tooth 45, it will shrink due to the extrusion of the inclined surface. When it is out of contact, the spring 47 immediately pushes it to reset. As the limit plate 31 slides, the positioning block 35 can pull the measuring ruler 61 to slide and extend inside the slide groove 24, so that the winding wheel 62 compresses the clockwork 63 to store force, so that the measuring ruler 61 extends or shrinks as the limit plate 31 slides up and down. The rubber sleeve 26 can clean the impurities adsorbed on the side wall of the measuring ruler 61 to ensure that the measuring ruler 61 is clean. After the main rod 22 and the positioning rod 23 completely contact the bottom surface inside the pile pit 7, the device is taken out through the probe rod 1. During the process of taking out the device, the stopper 45 limits the stopper 48, so that the stopper 45 and the gear 46 rotate clockwise, so that the housing 41 drives the limit plate 31 not to slide downward along the limit rod and the main rod 22. After the device is taken out from the pile pit 7, the scale of the measuring ruler 61 can be read, and the sum of the distance from the bottom end of the slide groove 24 to the bottom surface of the main rod 22 is equal to the thickness of the sediment 5. This device has the advantages of being able to accurately quantify the depth of the sediment 5 and being convenient for later reading and measurement.
[0033] Compared with the related art, the bored pile sediment detection device provided by the utility model has the following beneficial effects:
[0034] The utility model provides a sediment detection device for cast-in-place piles, wherein the device can be probed downward into the interior of the pile pit 7 through the probe rod 1, and the limiting structure 3 will firstly abut against the sediment 5 on the bottom surface of the interior of the pile pit 7, at which time the limiting structure 3 will float on the surface of the sediment 5, and then the probe rod 1 continues to apply thrust downward, so that the probe rod 1 pushes the positioning structure 2 to slide downward inside the limiting structure 3 and insert into the interior of the sediment 5, until the bottom end thereof abuts against the bottom surface of the interior of the pile pit 7, and the limiting structure 3 will still float on the surface under the resistance of the sediment 5, and as the positioning structure 2 moves downward, the card and structure 4 will be on the positioning structure 2 when the positioning structure 2 moves downward. The positioning structure 2 will slide on the side wall, and at the same time, the limiting structure 3 will pull the measuring structure 6 to extend. When the bottom end of the positioning structure 2 completely contacts the bottom surface of the pile pit 7, it can be taken out by the probe 1. When taking it out again, the card and structure 4 will drive the limiting structure 3 to be carded on the side wall of the positioning structure 2, so that the position of the limiting structure 3 is positioned at the position where the positioning structure 2 is inserted into the depth of the sediment 5. After taking it out, the specific depth of the sediment 5 can be obtained according to the scale of the measuring structure 6 and the length between the bottom end of the positioning structure 2 and the bottom end extended from the scale structure. This device has the advantages of being able to accurately quantify the depth of the sediment 55 and being convenient for later reading and measurement.
