Description

Technical Field

[0001] This invention relates to the field of offshore construction platform technology, and in particular to a high-pile wharf offshore construction platform and its construction method. Background Technology

[0002] As a key structural form in port and marine engineering, high-pile wharves are widely used in the construction of coastal and inland river ports due to their significant advantages such as lightweight structure, adaptability to soft soil foundations, and minimal impact on water flow and sediment movement. Their typical structure mainly consists of two parts: the superstructure and the pile foundation. The pile foundation usually consists of a large number of steel pipe piles or concrete square piles, deeply driven into the foundation, serving as the supporting skeleton of the entire wharf. However, the entire construction process of high-pile wharves, especially its core procedures, is highly dependent on the water-based operating environment. Traditional construction methods mainly rely on large floating cranes, piling vessels, and other water-based operating vessels. In long-term engineering practice, this traditional model has exposed a series of pain points and bottlenecks that urgently need to be addressed: (1) Low construction efficiency and high cost. The daily operating costs of large water-based vessels are extremely expensive, and their mobilization, positioning, and coordination consume a lot of time. When carrying out pile foundation construction and upper beam and slab installation, different types of ships need to frequently enter and leave the site, move and position, and the collaborative operation process is complicated. The effective working time is greatly compressed, resulting in a long overall construction cycle and directly increasing the project construction cost. (2) Severely constrained by the natural environment. Offshore / water construction is extremely sensitive to marine environmental conditions (such as wind, waves, currents and tides). In weather with large waves or poor visibility, construction is often forced to stop to ensure safety. This "relying on the weather" characteristic causes a large number of non-productive shutdowns, greatly increasing the uncertainty of the construction period, especially in projects with strict requirements for the construction period, bringing huge performance risks. (3) Challenges in operation accuracy and quality control. Under the action of waves and surges, construction ships are always in a dynamic state of swaying. This instability brings great difficulties to the accurate positioning of pile foundations, verticality control, and accurate installation of upper prefabricated components, making it difficult to fully meet the requirements of high-standard projects, resulting in installation errors, which in turn affect the overall stress performance and long-term durability of the structure. (4) Prominent safety risks. Waterborne operations are inherently high-risk activities. Personnel, equipment, and materials are frequently transferred between the water and vessels, facing safety threats such as falling overboard, collisions, and capsizing. Furthermore, multiple vessels operating collaboratively within the same narrow waterway create numerous overlapping work points, making safety management difficult and significantly increasing the risk of accidents. Therefore, the construction of high-pile wharves currently faces four core challenges: efficiency, cost, safety, and quality. The existing construction model, dominated by discrete ship-machinery systems, has become a key bottleneck restricting the further development of high-pile wharf construction technology. Therefore, the industry urgently calls for a new, integrated waterborne construction equipment and method.

[0003] Against this backdrop, the present invention aims to propose "a high-pile wharf construction platform" and provide its specific construction method to solve the aforementioned problems. This invention is expected to significantly reduce reliance on large and expensive ship machinery, substantially improve construction accuracy and efficiency, effectively reduce safety risks and overall costs, thereby bringing a technological revolution to the construction of high-pile wharves and similar water structures.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In related technologies, high-pile wharves have an open structure, resulting in minimal wave radiation and minimal impact on water flow. High-pile wharves are suitable for various foundations suitable for pile driving, especially soft soil foundations. On rock foundations, embedded rock piles can be used. A floating construction platform, on the other hand, is a floating platform built on water, primarily used to facilitate wharf construction work by workers on the water. Existing floating construction platforms require fixed piles driven into the water to prevent the platform from swaying due to water flow. Related technologies disclose a high-pile wharf floating construction platform, including a working platform and connecting plates. First fixing rods are fixedly connected to the front and left and right sides of the top and back of the working platform, and second fixing rods are fixedly connected at equal intervals between two parallel first fixing rods. Fixing blocks are fixedly connected at equal intervals to the bottom of the working platform. Through the structural design of the threaded column, the triangular sliding block, the barb, and the connecting rod, the movement of the bottom of the hollow column's inner cavity pushes the triangular sliding block, allowing the barb to move out of the hollow column's inner cavity. This enables the hollow column to be firmly inserted into the soil, thus securely fixing the work platform to the riverbank. This achieves the goal of fixing the high-pile wharf construction platform to the riverbank without the need for additional fixing piles. However, the aforementioned related technologies still face positioning difficulties, making it hard to accurately fix the construction platform in a designated location, especially in environments with rapid currents or complex water conditions. The platform is prone to displacement, affecting the accuracy and safety of construction. To solve these problems, this application provides the following solution:

[0036] Reference Figures 1-5 This invention provides a high-pile wharf construction platform, comprising:

[0055] In one embodiment of the present invention, the mounting plate 24 and the mounting rod 25 limit the connection between the working platform 1 and the shore ground to ensure the stability of the platform; the track 26 serves as a moving part to provide a stable conveying channel for external equipment, making it convenient for the equipment to be moved from the shore to the working platform 1 and improving construction efficiency.

[0056] As an optional implementation, one end of several fixing plates 27 are fixedly connected circumferentially to the top of the inner wall of the positioning hole 6 and the inner wall of the positioning pile 2. The other end of the fixing plate 27 is equipped with a guide wheel 28. The positioning rope 5 is in contact with the guide wheel 28. A support frame 29 is installed on the working platform 1. A second winding roller 30 is installed on the support frame 29. The second winding roller 30 is used to wind up the positioning rope 5.

The buoyancy is adjusted to a suitable state according to the expected load and water level of the working platform 1. One end of the positioning rope 5 extends out from the positioning pile 2 and is guided through the corresponding positioning hole 6 of the working platform 1 to connect with the second winding roller 30.
