Description

Technical Field

[0001] The invention relates to the technical field of bored pile sampling, in particular to sampling and detecting equipment for cement bored piles on a conglomerate foundation in the Western Region. Background Art

[0002] Western Region conglomerate is primarily composed of thick, gray-black conglomerate and sandy conglomerate, interbedded with pale yellow sand and mudstone, and calcareous and semi-cemented. Widely distributed in piedmont areas and intermountain basins, it primarily comprises molasse deposits at the foot of the mountains. When constructing bored piles in Western Region conglomerate, attention must be paid to their quality. This is because the quality of bored pile placement affects the overall quality of the construction project. Therefore, after a certain period of time, cement sampling and testing is required at various locations within the bored pile. Because bored piles are located underground, sampling cement at the top of the pile is easier than sampling cement at other locations.

[0003] The sampling method for bored cement piles is to manually place a sampling bucket into the borehole to take out the cement. Most of the cement obtained in this way is cement on the surface of the bored cement pile. This is because during the placement of the sampling bucket, the cement on the bored cement pile will flow into the sampling bucket. When a closed container is used for sampling, on the one hand, the cement above and below the sampling depth will partially flow into the container. On the other hand, as the container is opened, the bubbles in the container cavity will enter the undried and solidified bored cement pile, causing a hollow layer and reducing the quality of the bored cement pile.

[0034] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0035] Example 1, see Figures 1 to 14 As shown, a sampling and testing device for cement piles in a conglomerate foundation in the Western Region includes a frame 1, to which a controller is fixedly connected, and further includes:

[0036] A vertical pressure control structure 2 connected to the frame 1;

[0037] The closed sampling structure 3 is connected to the vertical pressure control structure 2, and the closed sampling structure 3 includes a double-end expansion sealing mechanism 4 connected to the vertical pressure control structure 2. The vertical pressure control structure 2 controls the height of the double-end expansion sealing mechanism 4 based on the winding traction principle. The double-end expansion sealing mechanism 4 includes a first control valve 5 connected to the vertical pressure control structure 2. The first control valve 5 is connected to a first pneumatic deformation part 6. The first pneumatic deformation part 6 is connected to a second pneumatic deformation part 8 through a relay pipe 7. The first pneumatic deformation part 6, the relay pipe 7, and the second pneumatic deformation part 8 are connected to each other. The pneumatic deformation parts 8 are interconnected. When the first control valve 5 is in the open state, the vertical pressure control structure 2 controls the volume and shape of the first pneumatic deformation part 6 by adjusting the air pressure. The vertical pressure control structure 2 controls the volume and shape of the second pneumatic deformation part 8 by adjusting the air pressure. The relay tube 7 is connected to a negative pressure sampling part 9. The negative pressure sampling part 9 is arranged between the first pneumatic deformation part 6 and the second pneumatic deformation part 8. The first pneumatic deformation part 6 and the second pneumatic deformation part 8 have the same structure and are symmetrically arranged.

[0038] A counterweight vibration portion 10 installed at the lower end of the second pneumatic deformation portion 8, the counterweight vibration portion 10 is used to close the lower end of the second pneumatic deformation portion 8 and provide a vibration force to the closed sampling structure 3;

[0039] The stable air pumping structure 11 connected to the frame 1 is used to perform air pumping operations and clamping and limiting operations on the negative pressure sampling part 9.

[0040] When in use, the stable exhaust structure 11 limits the negative pressure sampling part 9 and performs the exhaust operation, so that the air pressure inside the negative pressure sampling part 9 is reduced to reduce the air content inside the negative pressure sampling part 9, and then the vertical pressure control structure 2 is vertically placed into the cement to drive the first control valve 5 to move. The first control valve 5 drives the first pneumatic deformation part 6 to move, and the first pneumatic deformation part 6 drives the second pneumatic deformation part 8 to move through the relay pipe 7, so that the double-end expansion sealing mechanism 4 falls into the cement, and the second pneumatic deformation part 8 drives the counterweight vibration part 10 to move. Under the vibration of the counterweight vibration part 10, the double-end expansion sealing mechanism 4 and the negative pressure are assisted. The sampling part 9 moves downward in the cement, and then the pressure control structure 2 is vertically lowered to perform a pressurizing operation, and the first control valve 5 is opened, so that the first pneumatic deformation part 6 and the second pneumatic deformation part 8 expand, so that the first pneumatic deformation part 6 and the second pneumatic deformation part 8 block the drill hole filled with cement, and then a closed space is formed between the first pneumatic deformation part 6 and the second pneumatic deformation part 8, and then the negative pressure sampling part 9 is opened and closed after collecting the cement sample in the negative pressure sampling part 9 to perform a cement sample collection operation, and then the pressure control structure 2 is vertically lowered to perform a vacuum operation, and the closed sampling structure 3 is lifted to lift the closed sampling structure 3. The present invention cooperates with the vertical pressure control structure 2, the closed sampling structure 3, the counterweight vibration part 10, and the stable exhaust structure 11 to perform fixed-depth sampling operations on cement bored piles. During this period, the first pneumatic deformation part 6 and the second pneumatic deformation part 8 are blocked to limit the flow of cement in the borehole, thereby ensuring that the present invention performs fixed-depth sampling and ensures the accuracy of sampling. Moreover, since the negative pressure sampling part 9 is exhausted by the stable exhaust structure 11, it avoids the accidental hollowing of the cement layer due to sampling and air entering when the negative pressure sampling part 9 is opened. As the vertical pressure control structure 2 lifts the closed sampling structure 3, the counterweight vibration part 10 drives the cement to vibrate, so that the bubbles generated by sampling rise, thereby eliminating the influence of sampling on the quality of the bored piles and ensuring the quality of the cement bored piles.

[0041] In one case of this embodiment, the vertical pressure control structure 2 includes a box body 12 fixedly connected to the frame 1, and the outer wall of the box body 12 is fixedly connected to a dual-purpose pump for exhaustion and inflation 13, the box body 12 is fixedly connected to a first motor 14, the output shaft of the first motor 14 is fixedly connected to a wheel 15, a hose 16 is wrapped around the wheel 15, and the hose 16 is connected to a first driven wheel rotatably connected to the box body 12, one end of the hose 16 is communicated with the dual-purpose pump for exhaustion and inflation 13, and the other end of the hose 16 is fixedly connected to the first control valve 5, the frame 1 is fixedly connected to four groups of second motors 17, the output shaft of the second motor 17 is fixedly connected to a winding wheel 18, the winding wheel 18 is wrapped with a cable 19, the cable 19 is connected to the second driven wheel rotatably connected to the frame 1, and the four groups of cables 19 are commonly fixedly connected to a cross 20 fixedly connected to the first control valve 5. The second motor 17 controls the release and reeling of the cable 19 by driving the winding wheel 18 to rotate, thereby controlling the position of the cross 20 and further controlling the position of the closed sampling structure 3. The first motor 14 rotates the tube wheel 15 to control the release and reeling of the hose 16. Since the dual-purpose pump 13 for vacuuming and inflating is provided, the hose 16 connects the dual-purpose pump 13 for vacuuming and inflating and the first control valve 5, so that the dual-purpose pump 13 for vacuuming and inflating controls the air pressure in the first pneumatic deformation part 6 and the second pneumatic deformation part 8, thereby adjusting the volume and shape of the first pneumatic deformation part 6 and the second pneumatic deformation part 8.

[0042] In one case of this embodiment, the first pneumatic deformation part 6 and the second pneumatic deformation part 8 both include a hollow shell 21 fixedly connected to the relay tube 7, the hollow shell 21 is fixedly connected to an annular support piece 22, the hollow shell 21 is fixedly connected to a second control valve 23, the hollow shell 21 is fixedly connected to multiple groups of elastic telescopic frames 24, the moving ends of the multiple groups of elastic telescopic frames 24 are commonly fixedly connected to a lifting frame 25 slidably connected to the hollow shell 21, the lifting frame 25 is fixedly connected to an annular clamping plate 26 slidably connected to the hollow shell 21, the annular clamping plate 26 and the annular support piece 22 are commonly fixedly connected to an airbag 27, the annular support piece 22 is used to provide support for the airbag 27, the lifting frame 25 is hinged to multiple groups of rotating plate frames 28, the rotating plate frames 28 are connected to the inner wall of the airbag 27 Fixedly connected, each group of rotating plate frames 28 is hinged with two groups of sliders 29, and the two groups of sliders 29 are slidably connected to a group of limit frames 30. Each group of limit frames 30 is fixedly connected to a group of sleeves 31, and the sleeves 31 are fixedly connected to a one-way air outlet valve 32. The sleeves 31 are connected to the inner cavity of the hollow shell 21 through a branch pipe 33. The sleeves 31 are fixedly connected to the annular support piece 22. A first spring is fixedly installed in the sleeves 31, and the first spring is fixedly connected to a side top frame 34 slidably connected to the sleeves 31. The end of the side top frame 34 is fixedly connected to the inner wall of the airbag 27. The airbag 27 is an umbrella-shaped structure. The hollow shell 21 of the first pneumatic deformation part 6 is fixedly connected to the first control valve 5, and the hollow shell 21 of the second pneumatic deformation part 8 is fixedly connected to the counterweight vibration part 10. As the vertical pressure control structure 2 inflates the first pneumatic deformation part 6 and the relay tube 7 guides the air, the side frame 34 pushes the air bag 27 from the inner wall of the air bag 27 under the push of the air pressure, and as the air pressure in the sleeve 31 increases, the one-way air outlet valve 32 opens. At this time, the air pressure in the air bag 27 increases, so that the air bag 27 expands and deforms, so that the outer wall of the air bag 27 is in close contact with the borehole wall. As the cement squeezes the umbrella-shaped surface of the air bag 27 and the annular splint 26, the air bag 27 is squeezed. The rotating plate frame 28 and the annular clamp 26 support and flatten the plate frame 28 at the same time, and the annular clamp 26 is pressed. The annular clamp 26 drives the rotating plate frame 28 to rotate and move through the lifting frame 25. The rotating plate frame 28 and the slider 29 rotate relative to each other, and the slider 29 slides along the limit frame 30, so that the airbag 27 is deformed while maintaining the shape of the airbag 27, avoiding accidents of cement leakage due to the deformation of the airbag 27, and improving the sealing performance of the first pneumatic deformation part 6 and the second pneumatic deformation part 8.

The two groups of arc plates 46 are in staggered contact with each other, and the two groups of air bags 27 are fixedly connected to the upper and lower ends of the access shell 35 respectively. The first active telescopic rod 40 drives the partition 39 to move so that the storage chamber 36 and the air chamber 37 are connected to each other. After the stable exhaust structure 11 exhausts air through the third control valve 41, the first active telescopic rod 40 drives the partition 39 to move to separate the storage chamber 36 and the air chamber 37. The first electromagnet 44 magnetically attracts the permanent magnet 45 so that the permanent magnet 45 drives the arc plate 46 to move. As the staggered arc plates 46 separate, the cement flows into the storage chamber 36. Then the first electromagnet 44 is powered off. Under the push of the second spring on the permanent magnet 45, the arc plate 46 is reset to close the storage chamber 36.
