Description

Overwater transfer station for amphibious transportation

Technical Field

The utility model belongs to the technical field of bridge construction, and particularly relates to an on-water transfer station for amphibious transportation of bridge construction prefabricated parts.

Background

When the assembly technology is adopted for bridge construction, members such as a beam plate, a pier column, a capping beam, a tubular pile and the like of the bridge are prefabricated in a factory mode, and then are transported to a bridge construction site for installation. The prefabricated processing plant is positioned on an island near a sea entrance of a river, a finished prefabricated member is transported in a waterway intermodal mode, the prefabricated member is transported to a nearby port and a dock through a ship, and then transported to a construction site through a vehicle from the dock, but the distance from the dock to the construction site is far, the traffic is inconvenient, and the land transportation cost is high; moreover, the process time of the transport ship such as port entering, berthing, waiting berthing and the like is uncontrollable, the construction progress can be influenced, and the dock berthing and loading and unloading equipment use cost is high.

Disclosure of Invention

The utility model aims to solve the problems and provide an on-water transfer station for amphibious transportation, which is used for reducing construction cost.

The technical scheme of the utility model is as follows:

an on-water transfer station for amphibious transportation, which is characterized in that: the landing stage extends to a suitable ship navigation area in water from the bank, the two gantry crane tracks are respectively arranged at two sides of the landing stage along the bridge direction, and a ship berth is arranged between one gantry crane track and the landing stage; each gantry crane track comprises a plurality of steel pipe pile foundations, each steel pipe pile foundation comprises two foundation steel pipe piles, the lower ends of the two foundation steel pipe piles are inserted and beaten under a river bed to a certain depth, the upper ends of the two foundation steel pipe piles are higher than the water surface, parallel connection is arranged between the two steel foundation pipe piles, transverse spanners are erected in the transverse direction between the upper ends of the two foundation steel pipe piles, longitudinal spanners are erected on each transverse spanners along the bridging direction, and gantry crane sliding rails are paved on the longitudinal spanners; the two supporting legs of the gantry cranes are respectively supported on the sliding rails of the two gantry crane rails and slide along the sliding rails.

The utility model is equivalent to a temporary transfer wharf on water and can dock a transport ship with a certain tonnage. The transfer station is arranged on water, so that land use cost can be saved, the site of the transfer station can select a water area close to a construction site as much as possible, the land transportation distance and cost are reduced, the cost advantage of water transportation is brought into full play, and compared with a port and dock transportation mode, the comprehensive cost is lower.

The utility model is also suitable for transporting materials from land to the construction area in water during construction of the bridge on water.
