Description

A Safer Caisson Wharf Structure

technical field

The utility model relates to a gravity type wharf, in particular to a safer caisson type wharf structure.

Background technique

Gravity wharf is a type of wharf structure that is widely distributed and widely used in my country. Its structure is sturdy and durable; it has good frost resistance and ice resistance; it can withstand large ground loads and ship loads, and has strong adaptability to large concentrated loads, overloading of the wharf ground and changes in loading and unloading processes; and the construction is simple and the maintenance cost is small. . Gravity wharves require a good foundation and a certain bearing capacity, and are suitable for Northeast my country, Hebei, Shandong, Fujian, Guangzhou, Guangxi, and some areas such as the Yangtze River and Xijiang. Gravity caisson wharf mainly depends on the caisson, parapet, the weight of filler inside and outside the caisson and the strength of the foundation to maintain stability. However, the existing gravity wharf has problems such as serious frontal wave reflection, poor berth conditions, and unreasonable force.

Utility model content

The purpose of the utility model is to provide a safer caisson-type wharf structure, which can reduce the resistance coefficient of water flow and improve the stable condition of mooring by adopting an elliptical caisson.

In order to solve the problems of the technologies described above, the utility model adopts the following technical solutions:

A more secure caisson-type wharf structure consisting of a foundation bed, a caisson filled with backfill, a parapet and a pier face filled with backfill underneath; Backfill is filled between the wharf surface and the caisson; the section of the caisson is elliptical, and the long axis of the caisson is perpendicular to the front line of the wharf, that is, the long axis of the caisson is perpendicular to the direction of the wharf shoreline, which affects the safety of the ship. The larger water flow will impinge on the caisson along its long axis. Therefore, a streamlined caisson can reduce the resistance to waves, and has a good wave dissipation effect. The reflected wave intensity generated after the wave hits the caisson will also be small, thereby reducing waves, improving the berthing conditions in the front waters of the wharf, and improving the efficiency of berthing ships. safety factor.

In the aforementioned safer caisson-type wharf structure, the caisson is a reinforced concrete prefabricated component, and the wall thickness of the caisson is greater than or equal to 0.5 meters.

As one of the possible implementation methods, in the aforementioned safer caisson-type wharf structure, the length of the major axis of the caisson is greater than or equal to twice the length of the minor axis and less than or equal to five times the length of the minor axis .

In the aforementioned safer caisson wharf structure, the thickness of the two ends of the caisson in the long axis direction is greater than the thickness of the two ends in the short axis direction, and the thickness of the side near the water is greater than the thickness of the side near the shore. The water side of the long axis of the caisson is more directly affected by the force of ships, waves, and water flow than other directions, so increasing the thickness can improve the anti-scouring ability of the caisson and increase the service life of the caisson.

In the aforementioned safer caisson-type wharf structure, the breast wall is provided with a fender and a strike plate on the water side, and the fender is located between the strike plate and the breast wall.

Compared with the prior art, the utility model adopts an elliptical caisson, which can effectively improve the carrying capacity of the wharf structure compared with the conventional circular and rectangular caissons. The long axis of the caisson is perpendicular to the front line of the wharf, which can reduce the The water flow resistance coefficient is good, the wave dissipation effect is good, the wave reflection ability of the water area where the ship is moored at the front of the wharf is weakened, the mooring stability conditions are improved, and the ship is safer when berthing at the wharf.
