Pile foundation wide bearing platform high retaining wall wharf structure

Abstract

The invention discloses a pile foundation wide bearing platform high retaining wall wharf structure. The wharf structure comprises foundation piles, a wide bearing platform and a high retaining wall;the tops of the foundation piles are integrally and fixedly connected with a bottom plate of the wide bearing platform, and the high retaining wall is integrally and fixedly connected with the wide bearing platform; the lower portion of the wide bearing platform is provided with an inclined riprap layer; the lower portion of the high retaining wall is provided with a toe board in the water side direction, and the toe board is integrally and fixedly connected with the wide bearing platform and the high retaining wall; a wheel protection ridge is poured at the top of the high retaining wall; andthe high retaining wall is internally provided with drainage pipes extending to the rear portion of the wall, a crushed stone layer and backfill soil are arranged behind the high retaining wall, anda wharf surface layer is built at the tops of the crushed stone layer and the backfill soil. The pile foundation wide bearing platform high retaining wall wharf structure is suitable for regions whereinland rivers are large in water level difference, and poor complex geological conditions, especially a foundation of which a shallow part below the mud layer has a quicksand layer or other soft layers and other poor geological conditions; compared with a traditional structure, the structure is good in integrity and durability, meanwhile, construction is easy, the foundation treatment engineeringamount and the sand and stone use amount can be remarkably decreased, and the engineering construction cost is substantially reduced.

Description

technical field [0001] The invention relates to a hydraulic structure of a port wharf, in particular to a wharf structure with a pile foundation, a wide cap, and a high retaining wall, which is suitable for inland river areas with large water level differences and foundations with unfavorable and complicated geological conditions, and belongs to the technical field of port wharf engineering. Background technique [0002] At present, inland wharves play a very important role in water transportation. Quicksand layers or unfavorable soft soil layers widely exist in inland river areas such as the Jianghuai River Basin in my country, and the geological conditions are relatively complicated. Restricted by construction conditions or navigation conditions, inland river wharves in my country often carry out dry construction or dry excavation construction through cofferdams during the construction process. Generally, there are unfavorable and complex foundation conditions such as qui...

AI Technical Summary

Problems solved by technology

Generally, there are unfavorable and complex foundation conditions such as quicksand layers or other weak layers, and the bearing capacity of the foundation soil is very poor, making construction difficult, and it is difficult to build traditional wharves.

For areas with large water level differences in inland rivers, there are unfavorable and complex geological conditions such as quicksand layers or other weak layers in the shallow foundations. Due to the constraints of construction conditions, use conditions and economic conditions, it is neither suitable nor appropriate to adopt the traditional high-pile wharf structure type. Uneconomical

Adopting the traditional gravity wharf structure with many applications, due to the existence of quicksand layer or bad soft soil layer, not only the construction is difficult, but also the complexity of foundation treatment and the amount of sand and gravel materials are greatly increased
