The structural type, construction equipment and construction technology of traditional high-pile wharfs have greatly affected the construction progress, quality, cost and safety of high-pile wharfs.

Pile cores and pile caps are usually located in areas where tide levels change. Traditional construction techniques are cast-in-place operations on the water. Pile core construction includes water pumping in steel pipe piles, lowering steel cages, concrete pouring, etc. Pile cap construction includes the erection of complex bottom form supports at the bottom. system, on-site lashing of steel bars, installation of formwork and larger amounts of concrete pouring. The above water construction is easily affected by wind, waves and tide levels, and the construction window is limited and the work efficiency is low; the steel bars located in the splash zone are prone to rust and the construction quality is poor; the water work volume is large and the safety risks are high.

The top of the pile core 2 is connected to the first steel bar, and the two sides of the prefabricated beams (8, 9) The end is connected to the second steel bar. The diameter of the prefabricated pile core 2 is controlled according to the 80mm to 100mm gap between the pile core 2 and the inner wall of the steel pipe pile 1. The construction platform 6 is divided into a combination of two inclined piles and a three inclined pile. The length, width and height of the prefabricated construction platform 6 of the two inclined pile combination are 6500mm respectively. ×4000mm×800mm, the prefabricated construction platform 6 of the three-incline pile combination is a profile structure, with a length, width and height of 7500mm×5000mm×800mm respectively.

When the entire construction equipment needs to be moved to the next construction position, The auxiliary beam 27 is driven by the traveling mechanism 212 to move directly above the installed construction platform 6, and the auxiliary legs 28 are extended downward and supported on the corresponding construction platform 6, so that the bottom of the base structure 21 is detached. Corresponding to the construction platform 6, the corresponding traveling mechanism 212 on the main longitudinal beam 24 drives the main longitudinal beam 24 to move along the length direction, driving the base structure 21 to move to the next construction platform 6, and retracting the auxiliary legs 28 , re-support the base structure 21 on the construction platform 6 below, and then move the auxiliary beam 27 on the main longitudinal beam 24 to the initial position through the walking structure of the auxiliary beam 27, completing the over-span forward movement of the base structure 21. After that, the aforementioned operations are repeated, and the rotating structure 23 drives the mobile crane 26 and the spreader 210 to retrieve materials and lower them for installation until all the construction platforms 6, pile cores 2, and prefabricated beams (8, 9) of the entire wharf are installed. ) to complete the hoisting.

By setting up construction equipment, the construction equipment is supported on the construction platform 6 on top of the pile, which is not affected by waves and tidal currents, and the operating window is increased.

The width of the platform 6 controls the overall frame size of the construction equipment within a reasonable range, which has both good economy and construction efficiency. Among them, the base structure 21 and the base legs 22 provided at the bottom ensure that they can be symmetrically supported on four construction platforms. 6 is enough. In order to ensure the hoisting operation, when constructing at each construction platform 6, the current hoisting area needs to be larger than the construction area required for a single construction platform 6.
