Description

Technical Field

[0001] The utility model relates to the technical field of foundation construction, in particular to a flip-type slurry collecting device. Background Art

[0002] In order to solve the problems of large strength loss, low test values and large discreteness of test results in the core strength test of cement mixing piles, on-site slurry sampling and testing strength values are closer to the truth, and have the advantages of simple operation, low cost and fast speed. Compared with indoor specimen experiments and core strength test, it has obvious advantages and is the development direction of cement soil mixing pile strength testing.

[0003] At present, slurry sampling machines at home and abroad are all combined with the SMW method (also known as the new type of cement-soil mixing pile wall, which is to insert H-shaped steel into the cement-soil pile to combine load bearing and anti-seepage and water retention, making it a retaining wall of a supporting structure with both load-bearing and anti-seepage functions.), and most of them rely on their core material - H-shaped steel to deliver the slurry sampling machine to the designated location. However, in actual application, due to the large amount of cement-mixed pile engineering for soft soil foundation reinforcement, complex geological conditions, differences in soil properties, and large changes in working conditions with pile depth, the sampling machine operation must also be combined with the SMW method pile driver, which has poor independence and is not easy to promote.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] The following is a detailed description of the flip-top pulp extraction device through a specific embodiment:

[0029] like Figures 1 to 3 As shown, the present invention provides a flip-top slurry extraction device, comprising: a slurry extraction barrel 1, with a barrel cover provided on the top of the slurry extraction barrel 1, the barrel cover being rotatably connected to the slurry extraction barrel 1; a drill rod 3, the drill rod 3 extending in a vertical direction, one end of the drill rod 3 being engaged and connected with the center of the barrel cover; a lifting device 4, one end of the lifting device 4 being connected to the drill rod 3, and the other end being connected to the outer wall of the slurry extraction barrel 1. A traction device 5 is provided at the bottom of the lifting device 4, one end of the traction device 5 being connected to the edge of the barrel cover, and the other end being connected to the end of the drill rod 3 near the slurry extraction barrel 1.

[0030] The slurry extraction barrel 1 can be a hollow container of any shape, with the top of the barrel 1 referring to the barrel opening. It is understood that the outer diameter of the barrel cover is smaller than the inner diameter of the barrel 1, allowing the cover to be rotatably connected to the barrel 1. Specifically, a rotating shaft can be provided at the center of the barrel cover, and rotating holes can be provided on opposite sides of the barrel 1. The barrel cover can be rotated by inserting the rotating shaft into the rotating holes. Therefore, when the barrel cover is horizontal, it can cover the barrel opening of the barrel 1, preventing slurry from entering the barrel. When the barrel cover is rotated to a set angle (which can be 0 degrees to 180 degrees), the barrel cover has a gap relative to the barrel 1, allowing slurry to enter the barrel. Furthermore, a drill rod 3 is provided on the upper portion of the barrel cover and is engaged with the barrel cover. Specifically, a groove can be provided in the barrel cover, and a protrusion can be welded to the end of the drill rod 3. The engagement of the protrusion with the groove allows the drill rod 3 to be connected and disconnected from the barrel 1. As will be appreciated, the central axes of the drill rod 3 and the slurry extraction barrel 1 coincide, preventing uneven force. Therefore, during the slurry extraction process, the movement of the drill rod 3 can drive the slurry extraction barrel 1. After slurry extraction, the drill rod 3 and the slurry extraction barrel 1 can be separated, making it easy to remove and replace the slurry extraction barrel 1 and providing greater adaptability. Furthermore, a lifting device 4 is provided. In this embodiment, the lifting device 4 can be any structure with a lifting function, such as a steel rope, one end of which can be wrapped around the drill rod 3 and the other end connected to the outer wall of the slurry extraction barrel 1. Specifically, multiple hooks can be provided on the outer wall of the slurry extraction barrel 1, evenly distributed along the outer wall of the barrel. Three hooks can be evenly distributed, with one end of the steel rope connected to the hooks to lift the slurry extraction barrel 1 after slurry extraction. The aforementioned traction device 5 is provided below the lifting device 4, meaning that, along the extension direction of the drill rod 3, the traction device 5 is provided closer to the slurry extraction barrel 1, while the lifting device 4 is provided farther away from the slurry extraction barrel 1. In this embodiment, the traction device 5 can be a steel rope with a traction function. A hook can be provided on the edge of the bucket lid, with one end of the traction rope connected to the hook and the other end to the drill rod 3. Therefore, lifting the drill rod 3 exerts force on one end of the bucket lid, causing the lid to open, preventing it from remaining horizontal. This allows the slurry to enter the bucket. Subsequently, the drill rod 3 is further lifted, exerting force on the lifting rope 42, allowing the slurry collection bucket 1, now filled with slurry, to be lifted out. This allows for quick and convenient slurry collection.

[0031] The flip-top slurry extraction device of the present invention operates as follows: the drill rod 3 is engaged with the bucket lid, the lifting device 4 is mounted on the drill rod 3 and the bucket body, and the pulling device 5 is mounted on the drill rod 3 and the bucket lid. The slurry extraction bucket 1 is placed upright at the center of the newly completed pile hole, with the bucket lid closed. The bucket 1 is in a tightly closed, empty state. The pile driver is activated, and the rotation of the drill rod 3 drives the slurry extraction bucket 1 in the same direction. The slurry extraction bucket 1 drains and sinks, with the lid remaining closed under the pressure of the drill rod 3. When the top of the slurry extraction bucket 1 reaches the designated position, the drill rod 3 is slowly lifted after a brief pause, initially engaging and separating the drill rod 3 from the bucket 1. After further lifting, the lid flips open under the traction of the attached steel rope. At this point, the slurry extraction bucket 1 remains in the designated position. After the lid is opened, the cement-soil slurry near the bucket opening rapidly fills, and the pile foundation pauses for approximately one minute. The drill rod 3 is then raised at the normal drilling speed. The lifting device 4 of the slurry bucket 1 is then applied with force, lifting the slurry bucket 1 upward. Since the slurry bucket 1 is already filled with cement-soil slurry at the designated location, slurry introduced along the way during the upward movement cannot displace the slurry within the bucket, enabling the device to obtain slurry from different locations. After the slurry is extracted, samples are prepared on-site according to test requirements, and unconfined compressive strength tests are conducted under different working conditions, environmental curing conditions, and age periods.

[0032] The present invention provides a flip-top slurry extraction device. A slurry extraction bucket 1 is provided with a rotatably connected lid at the top of the bucket 1, allowing the lid to be flipped open and closed, thereby facilitating slurry extraction. Furthermore, a drill rod 3 extends vertically, one end of which engages the center of the lid, allowing the drill rod 3 to be detachably connected to the slurry extraction bucket 1. This allows the slurry extraction bucket 1 to be separated from the drill rod 3 when extracting cement slurry, facilitating access and replacement. Furthermore, a lifting device 4 is provided, one end of which is connected to the drill rod 3 and the other end to the outer wall of the slurry extraction bucket 1. A traction device 5 is provided below the lifting device 4, one end of which is connected to the edge of the lid and the other end to the end of the drill rod 3 near the slurry extraction bucket 1. Therefore, by lifting the drill rod 3, the traction device 5 causes the lid to flip, thereby opening and closing the lid. Then, by lifting the drill rod 3, the lifting device 4 causes the slurry extraction bucket 1 to be lifted, achieving the "empty bucket sinks, and the lid is lifted up" function. The device enables the acquisition of slurry from various locations. After the slurry is extracted, samples are prepared on-site according to test requirements, allowing for unconfined compressive strength tests under various working conditions, environmental curing conditions, and ages. The device boasts a simple structure, easy operation, and strong universal applicability.

[0033] In some embodiments, a support frame is provided inside the slurry barrel 1 , and the support frame is fixedly connected to the slurry barrel 1 .

[0034] The support frame can be of any shape as long as it can enhance the stability of the barrel. The support frame can be welded to the inner wall of the barrel using angle steel. It is understandable that the support frame will not affect the slurry collection of the slurry collection barrel 1.

[0035] Furthermore, the support frame includes a first frame 11 and a second frame 12. The first frame 11 is horizontally arranged on the top of the pulp barrel 1 and is fixedly connected to the inner wall of the pulp barrel 1; the second frame 12 extends in the vertical direction and coincides with the central axis of the pulp barrel 1. One end of the second frame 12 is connected to the bottom of the pulp barrel 1, and the other end is connected to the first frame 11.

[0036] The first frame 11 can be horizontally welded to the inner wall of the barrel mouth in a "well" shape. The second frame 12 can be vertically rod-shaped, with one end welded to the bottom of the barrel and the other end welded to the first frame 11. Aligning the second frame 12 with the central axis of the barrel ensures uniform force distribution when the barrel rotates with the drill rod 3, preventing tilting of the barrel due to eccentricity.

[0037] Furthermore, Figure 2 As shown, the first frame 11 includes an annular frame 111 and a cross 112. The annular frame 111 is circumferentially distributed along the inner wall of the pulp barrel 1, and the barrel cover abuts against the annular frame 111. The cross 112 is arranged inside the annular frame 111 and fixedly connected to the inner wall of the annular frame 111.

[0038] The dimensions of the ring frame 111 match the inner diameter of the barrel opening, allowing it to be welded securely to the opening. It will be appreciated that welding the ring frame 111 to the barrel opening creates a step, allowing the barrel lid to overlap the ring frame 111. Furthermore, crosses 112 are arranged along the two diameters of the ring frame 111, dividing it into four equal parts.

[0039] In some embodiments, the pulp bucket 1 is cylindrical with a diameter of 20 cm. Of course, it can also be of other sizes according to actual application.

[0040] In some embodiments, the barrel cover includes a first barrel cover 21 and a second barrel cover 22, which are horizontally arranged along the barrel mouth of the pulp barrel 1, and the ends of the first barrel cover 21 and the second barrel cover 22 close to each other are rotatably connected to the pulp barrel 1.

[0041] The size of the first bucket cover 21 and the second bucket cover 22 can be equal. It can also be two semicircles of equal size, and the diameters of the two semicircular bucket covers are adjacent and are rotatably connected to an edge of the cross 112.

[0042] Furthermore, a traction device 5 is provided on each of the first and second bucket covers 21, 22. On the first bucket cover 21, one end of the traction device 5 is connected to the edge of the first bucket cover 21, and the other end is connected to the drill rod 3. On the second bucket cover 22, one end of the traction device 5 is connected to the edge of the second bucket cover 22, and the other end is connected to the drill rod 3. Therefore, when the traction device 5 is subjected to force, the two semicircular bucket covers can be lifted and opened toward the center, which is convenient and labor-saving.

[0043] Furthermore, a first buckle 6 is provided at the center of the barrel cover, and a second buckle 7 is provided at the end of the drill rod 3 close to the slurry barrel 1 , and the first buckle 6 can be engaged with the second buckle 7 .

[0044] The first buckle 6 can be a recessed buckle, and the second buckle 7 can be a raised buckle. The first buckle 6 can be welded to the barrel cover, and the second buckle 7 can be welded to the drill rod 3, or connected by a flange. Of course, the first buckle 6 can also be welded to the second frame 12 so that the drill rod 3 can be conveniently positioned on the central axis of the barrel. In addition, the second buckle 7 can be provided with protruding ears on both sides so that the traction device 5 located on the first barrel cover 21 can be connected to the ears of the second buckle 7. Similarly, the traction device 5 located on the second barrel cover 22 can be connected to the ears on the other side of the second buckle 7.

[0045] In some other embodiments, the pulling device 4 includes a pulling ring 41 and a pulling rope 42. The pulling rope 42 is evenly distributed along the circumference of the pulling ring 41 and is fixedly connected to the pulling ring 41. The pulling ring 41 is sleeved on the drill pipe 3, and the end of the pulling rope 42 away from the pulling ring 41 is connected to the outer wall of the slurry barrel 1.

[0046] The lifting ring 41 can be formed by winding a steel rope into an annular structure. It is understood that the size of the lifting ring 41 matches the diameter of the drill rod 3 and will not slip during the lifting process. The lifting ring 41 and the lifting rope 42 can be formed by bending a single steel rope. It is understood that the lifting rope 42 is a flexible steel rope.

[0047] like Figure 3 As shown, the bottom of the pulp barrel 1 is a conical structure.

[0048] The bottom of the pulp bucket 1 is set to a conical structure so as to reduce the resistance of the slurry to the pulp bucket 1 during the descent process of the pulp bucket 1 and quickly sink to the designated position.
