Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a slurry sampling device and a construction method thereof. Background Art

[0002] Generally, for the detection of underwater cast-in-place pile slurry, the commonly used sampling method is to detect the slurry specific gravity, sand content, viscosity and other indicators with the slurry at the hole opening, and replace the performance indicators of the bottom-hole slurry with the measured performance indicators of the hole-opening slurry. Since the depth of engineering piles is currently relatively deep, especially for end-bearing piles formed by positive circulation rotary drilling and impact drilling, the content of soil residues, sand and other substances in the hole slurry is often relatively large, and will surely sink under the action of its own weight, resulting in a large difference between the bottom-hole slurry and the hole-opening slurry, and causing the slurry detection data in the hole to be inconsistent with the actual data. Especially for end-bearing piles with pile tip bearing force, if the slurry data in the hole is not accurately grasped, pile foundation quality accidents are more likely to occur. Summary of the Invention

[0003] Based on this, it is necessary to provide a slurry sampling device and a construction method thereof for the problems of how to obtain the bottom-hole slurry and improve the accuracy of slurry detection.

And the limiting component is arranged on the inner cylinder, and the limiting component is used to limit the moving distance of the outer cylinder relative to the inner cylinder. That is to say, when the outer cylinder moves to the position of the limiting component, the slurry taken is filled between the inside of the outer cylinder, the second substrate, and the end of the inner cylinder away from the first substrate, realizing the sampling of the bottom-hole slurry and improving the accuracy of slurry detection.

[0012] In one embodiment, the limiting component includes a limiting plate, a limiting ring, and a second connecting member.

[0026] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Please refer to Figure 1 and Figure 2 , the slurry sampling device 100 in one embodiment includes a first substrate 110, a second substrate 120, an inner cylinder 130, an outer cylinder 140, a first connecting piece 150, a limiting component, and a pulling component. The slurry sampling device 100 is used for sampling the bottom mud of the cast-in-place pile, so as to not only sample at the hole opening, but also realize sampling at the bottom of the hole, so as to obtain more accurate bottom mud data of the hole, improve the accuracy of mud detection, and avoid the occurrence of pile foundation quality accidents.

[0028] Specifically, the inner cylinder 130 is arranged on the first substrate 110, the outer cylinder 140 is sleeved outside the inner cylinder 130, one end of the outer cylinder 140 abuts against the first substrate 110, and the outer cylinder 140 can move relative to the inner cylinder 130 along the central axis direction of the inner cylinder 130. That is to say, the outer cylinder 140 moves relative to the inner cylinder 130, and the outer cylinder 140 moves up and down along the direction where the central axis of the inner cylinder 130 is located. The inner cylinder 130 can be filled with fillers such as gravel. It should be noted that both the first substrate 110 and the second substrate 120 can be steel plates. In this embodiment, the first substrate 110 is a circular steel plate, and the diameter of the first substrate 110 is the same as the outer diameter of the outer cylinder 140. The diameter of the second substrate 120 can also be the same as the outer diameter of the outer cylinder 140. By using steel plates for the first substrate 110 and the second substrate 120, not only can the strength of the pulp extraction device 100 be ensured, but also corrosion and the like can be reduced, the service life can be extended, and the overall mass of the pulp extraction device 100 can be reduced. In one embodiment, both the inner cylinder 130 and the outer cylinder 140 can be made of seamless steel pipes, and their sizes can be determined according to the actual construction site.

[0029] Further, the end of the inner cylinder 130 away from the first substrate 110 can be closed. That is to say, a cover plate is provided on the end of the inner cylinder 130 away from the first substrate 110. The inner cylinder 130 and the first substrate 110 can be fixedly connected by welding or other means.

[0030] The first connecting member 150 connects the other end of the outer cylinder 140 and the second substrate 120. That is to say, the second substrate 120 is located above the first substrate 110. The movement of the first connecting member 150 drives the movement of the outer cylinder 140. In this embodiment, the number of the first connecting members 150 is four, the cross-section thereof can be circular, and the material used can be steel. The four first connecting members 150 are evenly distributed along the edge of the outer cylinder 140.

[0031] The pulling assembly is arranged between the second substrate 120 and the inner cylinder 130 and can pull the pulling assembly to move away from or close to the first substrate 110. When the pulling assembly abuts against the second substrate 120, it drives the second substrate 120 to move away from the inner cylinder 130. Since the second substrate 120 is connected to the first connecting member 150, it drives the first connecting member 150 to move away from the first substrate 110. Also, since the first connecting member 150 is connected to the other end of the outer cylinder 140, it further drives the outer cylinder 140 to move away from the first substrate 110, while the inner cylinder 130 remains stationary. The limiting assembly is arranged on the inner cylinder 130, and the limiting assembly is used to limit the movement distance of the outer cylinder 140 relative to the inner cylinder 130. That is to say, the outer cylinder 140 moves relative to the inner cylinder 130 until the outer cylinder 140 abuts against the limiting assembly. Through the arrangement of the limiting assembly, the movement distance of the outer cylinder 140 is limited.

[0032] The above slurry sampling device includes a first substrate 110, a second substrate 120, an inner cylinder 130, an outer cylinder 140, a first connecting member 150, a limiting component, and a pulling component. The inner cylinder 130 is provided on the first substrate 110. The outer cylinder 140 is sleeved outside the inner cylinder 130, and one end of the outer cylinder 140 abuts against the first substrate 110. The outer cylinder 140 can move relative to the inner cylinder 130 along the central axis direction of the inner cylinder 130, that is, the outer cylinder 140 moves up and down along the central axis of the inner cylinder 130. The first connecting member 150 connects the other end of the outer cylinder 140 and the second substrate 120. The pulling component is provided between the second substrate 120 and the inner cylinder 130. When the pulling component abuts against the second substrate 120, it drives the second substrate 120 to move away from the inner cylinder 130. Through the lifting action of the pulling component, when the pulling component abuts against the second substrate, it drives the second substrate 120 to move away from the inner cylinder 130, and then drives the first connecting member 150 to move, so that the outer cylinder 140 also moves away from the inner cylinder 130, while the inner cylinder 130 remains stationary, so that the slurry begins to enter the inside of the outer cylinder 140, realizing the sampling of the bottom-hole slurry. And the limiting component is provided on the inner cylinder 130. The limiting component is used to limit the moving distance of the outer cylinder 140 relative to the inner cylinder 130. That is to say, when the outer cylinder 140 moves to the position of the limiting component, the slurry taken is filled between the inside of the outer cylinder 140, the second substrate 120, and the end of the inner cylinder 130 away from the first substrate 110, realizing the sampling of the bottom-hole slurry and improving the accuracy of slurry detection.

[0033] In one embodiment, the limiting component includes a limiting plate 161, a limiting ring 163, and a second connecting member 162. The limiting plate 161 is located between the second substrate 120 and the inner cylinder 130. The second connecting member 162 connects the second substrate 120 and the end of the inner cylinder 130 away from the first substrate 110. The limiting ring 163 is provided on the outer cylinder 140, and the limiting ring 163 is located above the inner cylinder 130. That is, when the outer cylinder 140 abuts against the first substrate 110, the limiting ring 163 abuts against the end of the inner cylinder 130. Among them, the second connecting member 162 and the inner cylinder 130 can be fixedly connected by welding or bolts and other means.

[0034] With the limiting component of this structure, when the pulling component is pulled to move away from the first substrate 110, the outer cylinder 140 also moves away from the first substrate 110 until the limiting ring 163 abuts against the limiting plate 161. At this time, the length of the second connecting member 162 is the moving distance of the outer cylinder 140 upward, and the slurry at the position where the outer cylinder 140, the limiting plate 161, and the end of the inner cylinder 130 are located is filled above, with a simple structure and convenient operation.

[0035] Further, in one embodiment, the pulling assembly includes a first hook portion 172, a second hook portion 171, and a first pulling rope 173. The first hook portion 172 is provided on the limiting plate 161. The second hook portion 171 is adapted to the first hook portion 172. The first pulling rope 173 is provided on the second hook portion 171. Among them, the first hook portion 172 can be connected to the limiting plate 161 by welding or bolts. When the slurry extraction device 100 is lowered to the bottom of the cast-in-place pile hole, the first pulling rope 173 is loosened, the first hook portion 172 is separated from the second hook portion 171, and the first pulling rope 173 is continuously pulled to drive the second hook portion 171 to move upward until the second hook portion 171 abuts against the second substrate 120. Thus, when the first pulling rope 173 is continuously pulled, the second substrate 120 can be driven to move upward, and then the outer cylinder 140 can be driven to move upward. In one embodiment, a through hole 121 is formed in the second substrate 120, and the first pulling rope 173 passes through the through hole 121. It should be noted that the diameter of the end portion of the second hook portion 171 is greater than the diameter of the through hole 121.

[0036] In one embodiment, the slurry extraction device 100 further includes a first sealing member 190. The first sealing member 190 is provided on the limiting ring 163. Thus, when the limiting ring 163 abuts against the limiting plate 161, the space formed among the outer cylinder 140, the limiting plate 161, and the inner cylinder 130 has sealing performance. The first sealing member 190 can be provided on the limiting ring 163 by pasting or other means.

[0037] Further, in one embodiment, the slurry extraction device 100 further includes a second sealing member 180. The second sealing member 180 is provided between the inner cylinder 130 and the outer cylinder 140 to ensure the sealing performance between the inner cylinder 130 and the outer cylinder 140.

[0038] In this embodiment, the cross-sections of the first substrate 110, the second substrate 120, the limiting plate 161, the outer cylinder 140, the inner cylinder 130, the first sealing member 190, and the second sealing member 180 can all be circular.

[0039] The working process of the above-mentioned pulp extraction device 100 is as follows: The first pulling rope 173 is tied to the second hook part 172. During the process of lowering the pulp extraction device 100 into the cast-in-place pile hole, the second hook part 172 hooks the first hook part 171. At this time, the inner cylinder 130 is inside the outer cylinder 140. When the first base plate 110 reaches the bottom of the cast-in-place pile hole, the first pulling rope 173 is released, so that the second hook part 172 falls freely and disengages from the first hook part 171. Then, the first pulling rope 173 is lifted, and the second hook part 172 abuts against the second base plate 120. The second base plate 120 is connected to the outer cylinder 140 through the first connecting member 150, so that the outer cylinder 140 moves upward, while the inner cylinder 130 remains stationary due to its own weight. During the lifting process, the mud at the position where the pulp extraction device 100 is located fills the space between the outer cylinder 140, the limiting plate 161, and the inner cylinder 130. When the limiting ring 163 abuts against the limiting plate 161, the first pulling rope 173 is pulled to lift the entire mud pulp extraction device.

[0040] In other embodiments, the limiting component includes a protruding part and a fixing part. The fixing part is arranged on the outer wall of the inner cylinder, and the protruding part is arranged at one end of the outer cylinder close to the first base plate, so that the protruding part can hook the fixing part.

[0041] At this time, in one embodiment, the pulling component includes a third hook part, a fourth hook part, and a second pulling rope. The third hook part is arranged on the inner cylinder, the fourth hook part is adapted to the third hook part, and the second pulling rope is arranged on the fourth hook part. It should be noted that in this embodiment, the other structures included in the pulp extraction device and the connection relationship between the structures are as described in the previous embodiment. With the limiting component and the pulling component of this structure, when the outer cylinder rises a certain distance, the mud fills the space formed between the second base plate, the outer cylinder, and the inner cylinder.

[0042] The construction method of the pulp extraction device in one embodiment includes the following steps: Lift the pulling component, and the pulling component abuts against the second base plate; continue to lift the pulling component to drive the first connecting member and the outer cylinder to move. The construction method of the above-mentioned pulp extraction device is convenient to operate. It should be noted that the pulp extraction device described in this embodiment is as described in the above embodiment, and will not be repeated here.

[0043] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0044] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
