Description

Technical Field

[0001] The utility model relates to a measuring device, in particular to a device for measuring the thickness of a sediment layer at the bottom of a bored pile hole in a bridge project, belonging to the technical field of measuring devices. Background Art

[0002] Bridge engineering is of great significance in infrastructure. It is an important link connecting two places, facilitating people's travel and the transportation of materials. The quality of bridge engineering is directly related to people's life safety and social development. It can also promote economic prosperity and regional exchanges and cooperation. In the construction process of bridge engineering, it is necessary to use drilling machinery to drill down into the ground to form a channel, and then place a steel cage in the hole and pour concrete to form a pile body. After the bored pile is bored, a sediment layer containing a mixture of uncleared drill cuttings, mud, sand and mud will be formed due to various reasons.

[0003] The sediment layer will cause serious damage to the column piles. It will reduce the bearing capacity of the piles and affect the stability of the piles, which will make the bridge as a whole unstable and cause engineering quality and safety problems. Therefore, it is necessary to measure the sediment layer to determine whether to pile in the hole. At present, the tool for measuring the sediment layer is a sediment thickness gauge. When the sediment thickness gauge is in use, the sediment thickness gauge is placed along the borehole to the bottom of the borehole using a connecting rope, and the thickness of the sediment layer at the bottom of the borehole is measured using the working principle of the sediment thickness gauge. However, when the sediment thickness gauge is in use, the connecting rope is no longer taut after the sediment thickness gauge contacts the bottom of the borehole. If the surface of the sediment layer is uneven, the instrument placed on its surface will be tilted or unstable, thereby affecting the measurement results of the instrument.

[0004] Therefore, there is an urgent need to improve the device for measuring the thickness of the sediment layer at the bottom of bored pile holes in bridge engineering to solve the above-mentioned problems. Utility Model Content

[0025] like Figure 1-Figure 7 As shown, the device for measuring the thickness of the sediment layer at the bottom of bored pile holes for bridge engineering provided in this embodiment includes an instrument body 2 with a circular plate 1, and a plurality of lifting support legs 3 with pin plates 301 are slidably connected to the circular plate 1, and the plurality of lifting support legs 3 are equidistantly arranged around the central axis of the circular plate 1, and a plurality of through holes 10 are opened on the circular plate 1, and the through holes 10 facilitate the passage of water, and a plurality of power supply components 11 are fixedly connected to the circular plate 1, and the plurality of power supply components 11 are equidistantly arranged, and the power supply components 11 provide power to the driving structure 6 while their equidistant distribution can also balance the weight of the driving structure 6, so that the center of gravity of the circular plate 1 coincides with the center of gravity of the instrument body 2, and a plurality of card slots 302 are opened on the lifting support legs 3, and a pushing structure 4 is rotatably connected to the upper surface of the circular plate 1, and a buckle assembly 5 is provided on the pushing structure 4, and the pushing structure 4 drives the buckle The component 5 is connected to the card slot 302, thereby fixing the position height of the lifting support leg 3. A driving structure 6 for driving the pushing structure 4 is provided on the circular plate 1. Through the pin plates 301 on several lifting support legs 3 and contact with the surface of the sediment layer, several lifting support legs 3 can change the position height relative to each other according to the concave and convex parts of the sediment layer surface. Then the driving structure 6 is used to drive the pushing structure 4 to rotate on the circular plate 1 as a whole, and then the snap assembly 5 is engaged with the card slot 302, thereby fixing several lifting support legs 3. At this time, several lifting support legs 3 are supported on the uneven surface of the sediment layer, and each lifting support leg 3 has a support point, thereby making the circular plate 1 and the instrument body 2 stable, ensuring the stability of the instrument body 2 during measurement, and not prone to tilting, thereby ensuring the accuracy of the measurement results.

[0026] Among them, Figure 1 as well as Figure 6 As shown, the pushing structure 4 includes an arc ring 401 that is sleeved on the outside of one end of the lifting support leg 3 and an arc plate 402 that fixedly connects two adjacent arc rings 401. Several arc plates 402 connect several arc rings 401 together to form a whole. The arc ring 401 does not contact the lifting support leg 3. The arc plate 402 is slidably connected to the circular plate 1. The establishment of the arc ring 401 ensures that the pushing structure 4 will not collide with the lifting support leg 3 when rotating.

[0027] Further, such as Figure 1 as well as Figure 6As shown, the driving structure 6 includes a motor 601 fixedly mounted on the circular plate 1, a rotating gear 602 connected to the output end of the motor 601, and a rack 603 fixedly connected to one of the arc-shaped plates 402.

The end of the sliding track 7 close to the circular plate 1 is fixedly connected to a trigger switch 9, and the trigger switch 9 is electrically connected to the motor 601. After the circular plate 1 drops to a certain height, the surface of the sediment layer squeezes the trigger member 8 to contact the trigger switch 9.

There are a transverse plate 12 and a torsion spring fastener 13, which are movably connected to the transverse plate 12 and the torsion spring fastener 13. When the arc ring 401 moves, the push plate 501 drives the fastening plate 504 to slide in the slide groove 502 through the hinge 503. When the fastening plate 504 moves in the direction of the lifting support leg 3 and is fastened to the slot 302, the lifting support leg 3 is fixed. When the arc ring 401 moves, one end of the torsion spring fastener 13 is fastened to the transverse plate 12, thereby reinforcing the fastening state between the fastening plate 504 and the slot 302.

When the device is placed, one end of the plurality of lifting support legs 3 located on the pin plate 301 will first contact the upper surface of the sediment layer. While the sediment layer supports the lifting support legs 3, the instrument body 2 will drive the circular plate 1 to continue to descend under the action of gravity, and the plurality of lifting support legs 3 will continuously change the positional relationship between the plurality of lifting support legs 3 according to the concave and convex shapes of the surface of the sediment layer, wherein the pin plate 301 on the convex will be higher than the pin plate 301 on the concave The foot plate 301, during the process of the circular plate 1 continuing to descend, until the surface of the sediment layer squeezes the trigger member 8 and contacts the trigger switch 9, the motor 601 is started, and the motor 601 drives the rotating gear 602 to rotate, thereby driving the rack 603 to move its position, and the movement of the rack 603 drives the arc plate 402 to move, thereby driving the pushing structure 4 to rotate as a whole on the circular plate 1, and then engages with the card slot 302 through the snap assembly 5, thereby fixing the several lifting support legs 3 in unused positions. At this time, under the action of the several lifting support legs 3, the instrument body 2 is in a stable vertical state, and the stability of the instrument body 2 during measurement is ensured.
