Definition A building on the seashore or riverside for passengers to get on and off and for cargo loading and unloading. (Usually seen in commercial cities with developed water and land transportation) The number of berths at the wharf is determined separately according to the type of cargo. In addition to the berths required for loading and unloading cargo and embarking and disembarking passengers, there are also berths for auxiliary vessels and ship repair docks in the port The length of the dock line is determined by the safe distance between the captain and the vessel that may dock at the same time.
Wharf structure A hydraulic structure for ships to dock, load and unload cargo, and to load and disembark passengers. The vertical dock is widely used, which is convenient for ships to dock and machinery to drive directly to the front of the dock to improve the efficiency of loading and unloading. In areas with large inland water level differences, sloped wharves can also be used, and barges are provided in front of the ramp for wharf use; Due to the many loading and unloading links in this kind of wharf, it is difficult for machinery to get close to the front edge of the wharf, and the loading and unloading efficiency is low.
Floating wharves can also be used in rivers and lakes with small water level differences, and in harbor basins protected by natural or artificial cover, with the help of movable approach bridges to connect barges to shores, such wharves are generally used as passenger terminals, fish unloading docks, ferry terminals and other auxiliary terminals.
The wharf structure forms include gravity type, high pile type and sheet pile type. It is mainly determined according to the comprehensive consideration of the use requirements, natural conditions and construction conditions.
Gravity docks. The weight of the filler depends on the weight of the building and the structural range to maintain stability, the structure integrity is good, strong and durable, easy to repair after damage, there are integral masonry and prefabricated type, suitable for better foundations.
High Pile Pier. It is composed of foundation pile and superstructure, the lower part of the pile is driven into the soil, the upper part is higher than the water surface, and the upper structure has beam plate type, beamless large plate type, frame type and cushion cap type, etc. The high pile wharf is a permeable structure, and the waves and water currents can pass below the level of the wharf, which does not reflect the waves, does not affect the flood discharge, and can reduce siltation, which is suitable for soft soil foundations.
In recent years, long piles and long-span structures have been widely adopted, and large prestressed concrete columns or steel pipe columns have been gradually used to replace piles with smaller sections to form pipe column wharves.
Sheet pile terminal. It is composed of sheet pile wall and anchor block facilities, and with the help of sheet pile and anchor block facilities, it bears the lateral pressure generated by the ground use load and the fill behind the wall. The sheet pile wharf has a simple structure and fast construction speed, and can be used except for particularly hard or too weak foundations, but the structural integrity and durability are poor.
This paragraph] modern industrial wharf refers to the loading and unloading place (such as manufacturing enterprises, logistics and warehousing enterprises, distribution centers, etc.) to build a raised loading and unloading platform (wharf), with the help of the platform to solve the vertical drop between the transport vehicle and the ground, usually the platform height adjustment plate will be installed on the platform, to solve the fine-tuning of the height drop and the gap between the fixed platform and the vehicle.
At this point, the handling forklift can safely and quickly enter and exit the transport vehicle for loading and unloading operations. As a pontoon between the platform and the transport vehicle, the height adjustment plate has become an essential equipment for modern industrial docks.
