Description

Arrangement structure for inland river roll-on wharf

Technical Field

The utility model relates to an arrangement structure, in particular to an arrangement structure for a rolling wharf of an inland river, and belongs to the technical field of design and manufacture of inland river channel transportation engineering structures.

Background

The water transportation is a transportation mode with strong transportation capability, less energy consumption and low transportation cost.

The roll-on transportation refers to a transportation mode for loading and transporting goods together by using a roll-on ship in a vehicle. The transportation objects are mainly containers and other grouped goods, and are generally shipped by trailers or trucks, and after the containers are loaded on a ship, the trailers and the trucks are also shipped together with the goods and are not loaded reversely. The roll-on transportation has the characteristics of less wharf investment, high loading and unloading efficiency and flexible transportation mode, can meet most of large-piece transportation requirements, and realizes door-to-door transportation.

The roll-on transportation of inland rivers can be used for transporting along the upstream and downstream of a navigation channel, can also be used as a ferry communication left bank and right bank, and has more applications in rivers, lakes, reservoirs and the like.

The arrangement of the roll-on wharf of the inland river has several outstanding technical characteristics compared with the roll-on transportation of the ocean.

1. The land line resources, inland rivers, particularly river channels in mountainous areas, have steep terrain on both sides, and limit the land line for arranging the wharf;

2. the direction of the water flow, the direction of the sea waves is roughly vertical to the coast, and the direction of the water flow of the inland river is parallel to the shoreline;

3. on the terrain, the topography of the coastal region is generally flat, and the topography of two banks of the inland river is steep, so that the local arrangement of the digging type harbor basin is difficult.

The most suitable arrangement is for the ramp of the roll-on loading dock to be oriented perpendicular to the contour, taking into account topographical considerations at the dock, as shown in figure 1. The arrangement mode has small digging and filling amount, but the direction of stopping the ship is vertical to the water flow, and the ship is influenced by the transverse water flow when stopping, so that the operation safety risk can be brought.

According to the requirements of ship docking, the slope direction of the roll-on wharf is approximately parallel to the contour line or intersects the contour line at a small angle, as shown in fig. 2. For roll-on wharfs with a plurality of berths, the river side is difficult to operate in deep water, and the mountain side has high excavation gradient and large excavation square amount.

According to the analysis, the traditional arrangement mode of the roll-on wharf is difficult to solve the contradiction between safe ship berthing and wharf engineering investment.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: the arrangement structure for the inland river roll-on-roll-off wharf is relatively small in engineering investment and relatively small in ship loading and engineering construction difficulty.

Furthermore, each group of rolling and loading berth groups at least comprises two rolling and loading berths, and each rolling and loading berth arranged adjacently in each group of rolling and loading berths shares one wharf ramp to be communicated with the wharf platform.

Preferably, the distance Lm between the two sets of rolling and loading ship berth groups is L + d, where L is the ship length and d is the berth margin length determined according to the relevant specifications.

Further, when the included angle between the center line of the roll-on/roll-off ship berth group and the riverside line is determined, the value is small when the water flow speed is large, and the value is large when the water flow speed is small, wherein the water flow speed is determined according to relevant specifications.

The preferable mode of the scheme is that the slope of each wharf slope way does not exceed 30-35 degrees.

Furthermore, the wharf platform comprises a plurality of sub wharf platforms the number of which is equivalent to that of the roll-on/roll-off berth groups, and one roll-on/roll-off berth group is respectively communicated with one sub wharf platform through one wharf ramp.

The utility model has the beneficial effects that: the arrangement structure provided by the application is based on the existing wharf platform and wharf ramp, at least two groups of rolling and loading berth groups which independently exist are additionally arranged, the central line of each group of rolling and loading berth group and the side line of the river bank form an included angle of 20-40 degrees and are arranged on the outer side of the wharf platform, and then each group of rolling and loading berth group is communicated with the wharf platform through the wharf ramp. Therefore, the situation that each roll-on ship berth is perpendicular to the water flow direction in the prior art is changed, meanwhile, the structure that a row of a plurality of roll-on ship berths are adjacently arranged side by side is changed into a structure arranged in groups, so that the amount of earth and stone excavated in the engineering of each roll-on ship berth group in the construction period is obviously reduced, the arrangement position of the roll-on ship entering the wharf after construction cannot cause the difficulty of river side deep water operation, and the purposes of relatively low engineering investment and relatively low difficulty in ship loading and engineering construction are achieved.
