Technical Field

[0001] The invention relates to a mud extraction device, in particular to a mud extractor used for extracting mud of different depths in a bored pile hole. Background Art

[0002] The main properties of mud include: mud specific gravity, viscosity, sand content, etc. For bored piles, mud properties play a decisive role in the quality of the piles, especially for processes such as rotary excavation and bottom expansion piles, which are extremely sensitive to mud properties. Therefore, it is necessary to collect detailed mud data in the hole, and sometimes even to collect mud at different depths in the hole for measurement. At present, the mud collectors in the industry have the disadvantages of high cost and narrow application range. There is an urgent need for a mud collector for mud at different depths in the hole. Summary of the invention

[0003] The invention aims to provide a slurry sampling device for slurry at different depths in bored piles, so as to obtain detailed parameters of the slurry in the hole and ensure that the quality of the piles meets the requirements.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a slurry sampler for different depths in a bored pile hole, comprising a top plate, a bottom plate, a waterproof leather, a steel pipe, a cover plate, a top plate hoop, a top plate measuring rope, a bottom plate hoop, and a bottom plate measuring rope, wherein the top plate and the bottom plate are connected by the top plate hoop and the bottom plate hoop with waterproof leather to form a spatially retractable cylindrical structure, the steel pipe passes through the bottom plate slurry inlet and is welded to the top plate, a cover plate is arranged at the bottom of the steel pipe, the bottom plate measuring rope is fixed on the bottom plate hoop and passes through the top plate hoop, and the top plate measuring rope is fixed at the center of the circle at the top of the top plate.

[0005] Furthermore, one end of the steel pipe is welded to the center of the top plate, and the other end is welded to the bottom cover plate, so that the bottom plate can slide up and down along the steel pipe.

[0006] Furthermore, the radius of the cover plate is greater than the diameter of the pulp inlet of the bottom plate.

[0007] A method for collecting slurry at different depths in a bored pile hole, using a slurry collector for collecting slurry at different depths in a bored pile hole, and the steps are as follows:

[0008] (1) By tightening the bottom plate measuring rope and making the top plate measuring rope loose, the slurry sampling device is placed into the bored pile hole to be sampled;

[0009] (2) When the scale of the bottom plate measuring rope reaches the target depth, tighten the top plate measuring rope to a tensioned state, and slowly loosen the bottom plate measuring rope, so that the bottom plate slowly sinks under the action of its own weight, and at the same time, the mud enters the internal chamber of the mud extractor from the mud inlet of the bottom plate; under the combined action of the mud inside the mud extractor and the deadweight of the bottom plate, the waterproof leather is stretched into place;

[0010] (3) Lift the top plate measuring rope and lift the slurry collector to the ground;

[0011] (4) Pour the slurry in the slurry extractor into the designated container to complete the slurry extraction work.

[0012] The beneficial results of the present invention are:

[0013] 1. The present invention has a simple structure, low cost, and convenient operation. Users can skillfully use the device after a simple introduction.

[0014] 2. The present invention is applicable to slurry collection operations at any depth from the hole mouth to the hole bottom, solving the problem that the previous slurry collector can only collect slurry after the device touches the hole bottom.

[0015] 3. The present invention solves the problem that the conventional slurry extractor cannot extract slurry smoothly due to the atmospheric pressure in the cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a further description of the embodiments of the present invention in conjunction with specific examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms are also applicable to the scope defined by the claims attached to this application.

[0021] like Figures 1 to 3As shown, the slurry extractor for slurry at different depths in bored piles of the present invention comprises a top plate 1, a bottom plate 2, a waterproof leather 5, a steel pipe 6, a cover plate 7, a top plate hoop 3, a top plate measuring rope 8, a bottom plate hoop 4, and a bottom plate measuring rope 9. The waterproof leather 5 is wrapped around a circle, pressed against the top plate 1 on the top, and connected to the bottom plate 2 on the bottom to form a spatial cylindrical structure, and the waterproof leather 5 is fixed tightly by using the top plate hoop 3 and the bottom plate hoop 4. To ensure that the gap is tight and watertight, the steel pipe 6 passes through the bottom plate 2 and is welded to the top plate 1, and a cover plate 7 is set at the bottom of the steel pipe 6. The bottom plate measuring rope 9 is fixed on the bottom plate hoop 4 and passes through the top plate hoop 3, and the top plate measuring rope 8 is fixed at the center of the top plate 1. The slurry extractor mainly utilizes the gravity of the bottom plate. When the device reaches a certain depth, the waterproof leather can stretch naturally driven by the bottom plate to extract the slurry at this depth.

[0022] One end of the steel pipe 6 is welded to the center of the top plate 1, and the other end is welded to the bottom cover plate 7. The bottom plate 2 can slide up and down along the steel pipe 6, and the radius of the bottom cover plate 7 is larger than the diameter of the bottom plate slurry inlet.

[0023] The specific operation method of the present invention is:

[0024] 1) By tightening the bottom plate measuring rope 9, the top plate measuring rope 8 is in a relaxed state, and the slurry sampling device is placed into the bored pile hole to be sampled.

[0025] 2) When the scale of the bottom plate measuring rope 9 reaches the target depth, tighten the top plate measuring rope 8 to a stressed and taut state, and slowly loosen the bottom plate measuring rope 9. At this time, the bottom plate 2 slowly sinks under the action of its own weight, and at the same time, the mud enters the internal chamber of the slurry extractor from the slurry inlet of the bottom plate; under the combined action of the mud inside the slurry extractor and the deadweight of the bottom plate 2, the waterproof leather 5 is stretched into place.

[0026] 3) Lift the top plate measuring rope 8 and lift the slurry collector to the ground.

[0027] 4) Pour the slurry in the slurry extractor into the designated container to complete the slurry extraction work.
