Description

Technical Field

[0001] This utility model belongs to the field of underwater construction technology, and in particular relates to a guiding device for underwater drilling and pile planting. Background Technology

[0002] In the pile foundation construction of docks and offshore wind power, bored pile installation is an important guarantee for the construction of steel pipe piles. The efficiency of pile installation directly affects the project progress and cost. In order to ensure the smooth completion of the project, it is necessary to promote the use of high-efficiency, high-quality and reliable construction technology such as bored pile installation.

[0003] Piling involves drilling holes in hard, bare rock, inserting steel pipe piles into the holes, and then pouring concrete to ensure sufficient anchorage length. This type of pile construction typically uses a drilling rig to drill holes at depths exceeding 5 meters into the bedrock. The pile is then placed into the hole, and concrete is poured in. After the concrete hardens, the pile is firmly fixed to the bedrock, and a temporary bridge or platform superstructure is then erected on top of it. However, during construction, the stability of the drilling rig cannot be effectively controlled, and drilling directly into the bedrock makes grout preparation difficult, resulting in lengthy drilling periods and a high risk of misalignment. While previous methods were simple in structure, they were not conducive to material conservation, did not significantly reduce construction time, and had poor economic efficiency.

[0004] At present, the guide frames generally used are "well"-shaped frames formed by I-beams as the main frame or horn-shaped round protective cylinders as guide devices. This type of customized guide frame has a small range of applications and is not flexible enough in adjustment, making it very easy to cause eccentricity and misalignment. Utility Model Content

[0005] To address the aforementioned problems in existing technologies, this utility model provides a guiding device for underwater drilling and pile driving. This device ensures accurate pile positioning and verticality while reducing the difficulty of pile driving. It features a simple structure, saves materials, and achieves good technical and economic benefits.

[0006] To solve the above problems, this utility model adopts the following technical solution:

Multiple sets of guiding components are detachably connected to the inner wall of the guide cylinder. Each set of guiding components is provided with an axis parallel to the axis of the guide cylinder and a guide roller that can rotate around the axis. The axis of the guide roller is parallel to the axis of the guide cylinder. The guide roller is connected to the guide cylinder through a connecting component.

[0009] Further, the outer wall of the guide cylinder is provided with a plurality of reinforcing steel plates, and the reinforcing steel plates are provided with hooks.

[0010] Further, the mounting base frame comprises two spaced longitudinal I-beams, and a transverse positioning frame is arranged between the two longitudinal I-beams, the transverse positioning frame is detachably connected with the longitudinal I-beams and perpendicular to each other, and the surface of the longitudinal I-beams is provided with a base plate.

[0011] Further, the bottom of the base plate is provided with a sliding groove, and the sliding groove is sleeved on the upper part of the longitudinal I-beam.

[0012] Further, the base plate is fixedly connected with the guide cylinder, and the reinforcing steel plate is connected between the base plate and the guide cylinder.

[0013] Further, the mounting base frame is mounted on a ship body or a platform to ensure that the center position of the guide cylinder is substantially coincided with the center position of the pile.

[0014] Further, the guide assemblies are symmetrically arranged on the wall of the guide cylinder, and the number of the guide assemblies can be set as 4, 6 or 8 according to the diameter of the inner wall of the guide cylinder.

[0017] 2. The guide device can be mounted on a ship body or a pile stabilizing platform, and only needs to be placed down through the I-beam, so that the process is simple and the construction efficiency is high.

[0018] 3. When the steel pipe pile is sunk, at least four rotating bearings are connected on the guide cylinder in contact with the steel pipe pile, so that the steel pipe pile is guided under the rotating bearings and prevented from eccentric displacement in the installation process through the resistance of the guide cylinder.

[0019] 4. According to the device, eccentric displacement of the steel pipe pile can be prevented in the steel pipe pile drilling and pile planting, and the effect is remarkable in preventing eccentricity in the underwater construction process.
