[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0025] Figure 1 and Figure 2 The utility model is used to clean and remove slag from pile foundation holes, so that the mud index and bottom sediment of the pile foundation hole meet the requirements of hole filling index. The structure is simple, efficient and low-cost.

[0026] like Figure 1 As shown, the pile foundation construction hole cleaning and slag dredging bucket 1000 includes a bucket body 1, a movable bottom plate 2, a lifting cable 3, and an opening and closing cable 4. The movable bottom plate 2 is located at the bottom opening of the bucket body 1 and is hinged to the bucket body 1. The movable bottom plate 2 opens by rotating downwardly toward the bucket body 1 and is used to seal the bottom opening of the bucket body 1 when closed. The lifting cable 3 is connected to the bucket body 1 and is used to drive the bucket body 1 to move up and down along the pile foundation hole. The opening and closing cable 4 is connected to the movable bottom plate 2 and is used to pull the movable bottom plate 2 closed relative to the bottom opening of the bucket body 1 by pulling up. The opening and closing cable 4 is also used to lower the movable bottom plate 2 to open relative to the bottom opening of the bucket body 1 by lowering. This enables the movable bottom plate 2 to reciprocate and open, thereby scooping sediment from the pile foundation hole into the bucket body 1 through the movable bottom plate 2.

[0027] Specifically, the pile foundation construction hole cleaning and slag scooping bucket 1000 drives the bucket body 1 to move up and down along the pile foundation hole through the lifting cable 3, and drives the movable bottom plate 2 to open and close reciprocally relative to the bottom opening of the bucket body 1 through the opening and closing cable 4, so that the movable bottom plate 2 can be impacted and inserted into the sediment at the bottom of the pile foundation hole and the sediment can be scooped into the inner cavity of the bucket body 2. The lifting and lowering action of the bucket body 1 and the reciprocating opening and closing action of the movable bottom plate 2 are repeated many times, and more sediment can be continuously scooped. After the barrel body 1 is full, the opening and closing cable 4 is tightened to close the movable bottom plate 2, and then the lifting cable 3 is pulled to bring the pile foundation construction hole cleaning and slag scooping bucket 1000 as a whole out to the ground, which is convenient for discharging the sediment in the bucket. The overall structure is simple and efficient, the slag scooping effect is good, it can be made from materials on the construction site, and can be flexibly adapted to different pile foundation hole sizes. It is low in cost and has strong applicability.

[0028] Please combine Figure 1 and Figure 2 Two movable bottom plates 2 are provided, and are disposed on opposite sides of the barrel body 1. The two movable bottom plates 2 are configured to be joined together when closed to jointly block the bottom opening of the barrel body 1. The two movable bottom plates 2 are used to perform slag scooping operations on opposite sides of the barrel body 1, respectively. This not only improves slag scooping efficiency, but also shortens the rotational travel of a single movable bottom plate 2, reduces the force applied to a single movable bottom plate 2, enhances the structural strength and stability of the movable bottom plates 2, and improves the slag scooping effect.

[0029] Preferably, the edge of the movable bottom plate 2, which is used for connecting with another movable bottom plate 2, is configured as a serrated structure 21. This serrated structure 21 is used to penetrate into the sediment in the pile foundation hole when the movable bottom plate 2 is in the open position. The serrated structures 21 of the two movable bottom plates 2 can be spliced ​​together and closed. That is, when the movable bottom plate 2 is in the open position, the edge of the movable bottom plate 2 facing away from the barrel body 1 is configured as a serrated structure 21, enabling impact slag breaking during descent, allowing for smoother penetration into the sediment, preventing the inability to thoroughly clean out deep sediment at the bottom of the pile foundation hole, and further improving the slag removal effect.

[0030] Preferably, two opening and closing cables 4 are provided, and the two opening and closing cables 4 are connected to the two movable bottom plates 2 in a one-to-one correspondence. The opening and closing cables 4 are arranged at the center position of one side of the movable bottom plate 2 close to the other movable bottom plate 2 .

[0031] By driving the opening and closing actions of the two movable bottom plates 2 respectively through two opening and closing cables 4, not only can the synchronous opening and closing of the two movable bottom plates 2 be achieved, but also the sequential opening and closing of the two movable bottom plates 2 can be achieved, different slag removal actions can be switched, and sediments in different states can be adapted. Secondly, since the opening and closing cables 4 are arranged at the center position of the movable bottom plate 2 on the side close to the other movable bottom plate 2, not only can the lever principle be used to reduce the force of the opening and closing cables 4, and the movable bottom plates 2 can be opened and closed more effortlessly, but also since the side of the movable bottom plate 2 close to the other movable bottom plate 2 is not connected to the barrel body 1, the movable end of the movable bottom plate 2 is fixed by the opening and closing cables 4, so that the movable bottom plate 2 is more stable and not easy to loosen, and can stably drive the sediment out of the ground.

[0032] Preferably, there are two lifting cables 3, which are arranged on opposite sides of the barrel body 1. The connection direction of the two lifting cables 3 is parallel to the rotating axis of the movable bottom plate 2, so that the connection direction of the two lifting cables 3 is perpendicular to the connection direction of the two opening and closing cables 4. The slag bucket is lifted together by the two lifting cables 3 and the two opening and closing cables 4 to improve stability.

[0033] In other embodiments, when there is only one movable bottom plate 2, since the connection direction of the two lifting cables 3 is parallel to the rotation axis of the movable bottom plate 2, the barrel body 1 can also be slightly rotated along the connection direction of the two lifting cables 3 as the axis, and the sediment is shaken into the barrel body 1, thereby improving the sediment scooping effect.

[0034] Furthermore, the barrel body 1 and the movable bottom plate 2 are both provided with a connecting ring 5, the lifting cable 3 is detachably mounted on the connecting ring 5 of the barrel body 1, and the opening and closing cable 4 is detachably mounted on the connecting ring 5 of the movable bottom plate 2. The lifting cable 3 and the opening and closing cable 4 are fixed by the connecting ring 5, making them easy to disassemble and use.

[0035] Furthermore, the barrel body 1 is formed into a cylindrical shape by enclosing steel plates and finalized by welding. The outer diameter of the barrel body 1 is adapted to the inner diameter of the pile foundation hole. The barrel body 1 has a simple structure and is easy to manufacture. It can be made from materials on the construction site, and the actual size can be precisely adjusted according to the inner diameter of the pile foundation hole.

[0036] Preferably, drainage holes (not shown in the figure, the same below) are provided on the barrel body 1 and / or the movable bottom plate 2, and the liquid in the inner cavity of the barrel body 1 is discharged through the drainage holes during the slag scooping process to avoid excessive mud from entering and occupying the slag scooping space.

[0037] Preferably, the pile foundation construction hole cleaning and slag scooping bucket 1000 also includes a hinge 6 arranged between the movable bottom plate 2 and the barrel body 1, and the movable bottom plate 2 is hinged relative to the barrel body 1 through the hinge 6, so that the movable bottom plate 2 can smoothly rotate and open and close relative to the barrel body 1.

[0038] As a second aspect, the utility model also provides a pile foundation construction equipment (not shown in the figure, the same below), including the above-mentioned pile foundation construction hole cleaning and slag bucket, the pile foundation construction equipment also includes an impact drilling pile driver, the main steel cable of the impact drilling pile driver is used as the lifting cable 3, and the auxiliary steel cable of the impact drilling pile driver is used as the opening and closing cable 4. The impact drilling pile driver can drive the pile foundation construction hole cleaning and slag bucket to any depth position of the pile foundation hole for hole cleaning operations without manual operation.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
