Anti-seepage seawall with pile foundation framework rib plate structures

Abstract

The invention provides an anti-seepage seawall with pile foundation framework rib plate structures. Pile foundation structures of the anti-seepage seawall are arranged in a preprocessed foundation; a pile top crown beam is arranged on the tops of the same row of pile foundation structures; the pile top crown beams are connected into a whole through connecting and tying beams; framework rib plate structures are arranged on the pile top crown beams and the connecting and tying beams; the interior of the framework rib plate structures are filled with solidification closure earthwork; the portions, on the two sides of each framework rib plate structure, of the preprocessed foundation are provided with anti-scouring structures; and under the joint effect of the preprocessed foundation and the pile foundation structures, adverse effects of common large seawall settlement and large horizontal displacement on adjacent buildings are avoided. The anti-seepage seawall with the pile foundation framework rib plate structures guarantees the safety of the adjacent buildings to the maximum extent, engineering investment is saved, the construction progress is accelerated, the environment interference is reduced, and the land utilization rate is increased.

Description

technical field [0001] The invention relates to an anti-seepage seawall, in particular to an anti-seepage seawall with a pile foundation frame rib plate structure, which is suitable for light anti-seepage seawalls requiring rapid construction and strict horizontal displacement control, especially for coastal The intersection structure of regional seawall and sea-crossing bridge, that is, the area where the settlement and horizontal displacement of seawall are strictly controlled. Background technique [0002] The development of marine economy is the focus and highlight of the 13th five-year development of Jiangsu and Zhejiang provinces. Jiangsu and Zhejiang provinces have or will soon introduce major project plans for marine economic development. The construction of foundation projects such as seawall projects in coastal areas and coastal traffic cross-sea bridges has become an important There are often intersections in the spatial layout of the project, but there are limita...

[0002] The development of marine economy is the focus and highlight of the 13th five-year development of Jiangsu and Zhejiang provinces. Jiangsu and Zhejiang provinces have or will soon introduce major project plans for marine economic development. The construction of foundation projects such as seawall projects in coastal areas and coastal traffic cross-sea bridges has become an important There are often intersections in the spatial layout of the project, but there are limitations in the use of traditional seawalls and many disadvantages: (1) The settlement is large and the horizontal displacement is also large (meter (m) order of magnitude). There are adverse effects such as lateral deformation on the pile foundation of bridge piers; (2) settlement and deformation occur slowly, especially post-construction creep and other settlements are still relatively large, which affects the safety of adjacent bridge piers and other buildings

(3) Since the foundation of tidal flats in coastal areas of Zhejiang is generally deep marine silt with low bearing capacity, the loading rate of general seawall construction is slow, which affects the progress of the project

(4) Generally, the seawall has a large cross-section and is a bit cumbersome as a whole, which has a great impact on nearby sensitive buildings and the environment
