Description

Technical Field

[0001] The invention relates to the technical field of rotary drilling and grouting construction, in particular to a high fill geological rotary drilling and grouting pile construction device and a construction method. Background Art

[0002] High fill geological rotary bored pile construction is a foundation treatment method that uses a rotary drilling rig to drill holes in areas with large fill volumes and complex geological conditions, and then places a steel cage in the hole and pours concrete to form a stable pile structure. This method can effectively enhance the bearing capacity and stability of the foundation and is suitable for various construction projects.

[0003] The existing high-fill geological rotary drilling and grouting pile construction equipment has some obvious shortcomings in the operation process. Since most construction equipment relies on heavy vehicles for movement and operation, these vehicles themselves are heavy. When they are close to the construction holes, they not only increase the bearing pressure of the foundation, but also easily lead to the risk of vehicle rollover or hole collapse due to unstable foundation. This will not only endanger construction safety, but may also have a serious impact on project progress and cost.

[0004] At the same time, the current construction method generally adopts a batch operation mode of first rotary drilling and then hoisting the steel cage. This construction method is not only cumbersome to operate and increases the construction period, but also during the installation of the steel cage, due to the insufficient connection with the rotary drilling hole, the position of the steel cage may be offset or tilted, thereby affecting the overall quality and stability of the pile body.

[0013] The present invention also discloses a construction method of a high fill geological rotary drilling bored pile construction device, comprising the following steps:

[0014] Step one, connect the mounting plate to the carrier and move the entire device to the designated construction location, then control the first motor to make the first gear engage with the second gear to rotate, thereby driving the cross stud to rotate. The cross stud is threadedly connected to the first threaded plate during the rotation, so that the first threaded plate drives the push plate to push the extension plate toward the drilling location as the cross stud rotates, then hoist the steel cage on the hook, and the second moving wheel at the bottom of the extension plate is supported by the ground during the movement.

Since the vertical stud is threadedly connected to one end of the lifting frame, the lifting frame moves downward with the rotation of the vertical stud, thereby sending the hoisted steel cage into the drill hole. While placing the steel cage, control the electric cylinder to push the translation plate to move horizontally on the two short guide rods, so as to adjust the position of the hoisted steel cage. When the steel cage is accurately placed at the predetermined position in the drill hole, stop the operation of the third motor and the electric cylinder, and then install the steel cage. After the installation of the steel cage is completed, finally pour the concrete and carry out subsequent work.

[0017] Compared with the prior art, the beneficial effects of the present invention include:

[0018] The high fill geological rotary drilling and bored pile construction device connects the device to the carrier through the design of a base, an extension plate, a transverse stud, a first threaded plate, a first motor, a first gear and a second gear. The device is moved as a whole to a designated construction site by the carrier. The first motor drives the first gear and the second gear to rotate in meshing, thereby driving the transverse stud to rotate, and then the first threaded plate is moved through a threaded connection, and finally the extension plate is pushed to move accurately toward the drilling site. The extension plate drives the upper construction mechanism to move to the site where construction is required. This design effectively avoids the risks of directly operating the construction mechanism through the carrier in the traditional method, which may cause unstable foundation and hole collapse due to the excessive weight of the carrier and directly approaching the hole. The second moving wheel at the bottom of the extension plate is supported by the ground, so that the carrier can be parked in a safe position far away from the hole, and the device itself can be accurately moved to the construction site for operation. The rotating plate, the rotating column, the second motor, the third gear The design of the wheel, the fourth gear, the hollow vertical plate, the vertical stud, the third motor, the lifting frame, the connecting plate, the electric cylinder, the translation plate, the hook and the rotary drilling mechanism. The second motor drives the third gear and the fourth gear to engage and transmit, so that the rotating column drives the rotating plate to rotate. This design enables rapid switching between the rotary drilling mechanism and the lifting mechanism, avoiding the need to use different devices for batch construction, greatly reducing the waiting time during the construction process, and improving the flexibility of the device and the overall construction efficiency. The third motor drives the vertical stud to rotate, thereby controlling the lifting of the lifting frame, thereby achieving rapid and accurate lifting of the steel cage. This operation method reduces the uncertainty and error of manual operation and further improves construction efficiency. The electric cylinder and the translation plate enable the steel cage to be accurately adjusted to the left and right position during the lifting process. This fine-tuning function ensures that the steel cage can be accurately placed in the predetermined position, avoiding quality problems caused by position deviation.

The third motor 21 drives the vertical stud 20 to rotate, thereby controlling the lifting and lowering of the lifting frame 22, thereby realizing rapid and accurate lifting of the steel cage.

The horizontal stud (3) is threadedly connected with the first threaded plate (4) during the rotation process, so that the first threaded plate (4) drives the push plate (12) to push the extension plate (2) to move toward the drilling site as the horizontal stud (3) rotates. Then, the steel cage is hoisted on the hook (29). During the movement of the extension plate (2), the second moving wheel (34) at the bottom thereof is supported by the ground. Step 2, controlling the second motor (15) to operate so that the third gear (16) engages with the fourth gear (17) to rotate, so that the fourth gear (17) drives the rotating plate (13) to rotate, so that the rotary drilling mechanism (31) on the rotating plate (13) moves to the right side, and the drill bit thereof drills a hole in the ground; Step 3: After the drilling work is completed, the second motor (15) is controlled again to drive the rotating plate (13) to rotate, so that the hollow vertical plate (19) rotates to the right, and then the steel cage is installed. First, the third motor (21) is controlled to drive the vertical stud (20) to rotate. Since the vertical stud (20) is threadedly connected to one end of the lifting frame (22), the lifting frame (22) moves downward with the rotation of the vertical stud (20), thereby sending the hoisted steel cage into the drill hole. While the steel cage is being placed, the electric cylinder (27) is controlled to push the translation plate (28) to move horizontally on the two short guide rods (26), thereby adjusting the position of the hoisted steel cage. When the steel cage is accurately placed at the predetermined position in the drill hole, the operation of the third motor (21) and the electric cylinder (27) is stopped, and then the steel cage is subsequently installed. After the steel cage is installed, concrete pouring and subsequent work are finally carried out.
