Construction method for improving bearing capacity of seawall armor foundation

Abstract

The invention discloses a construction method for improving the bearing capacity of a seawall armor foundation. The method comprises the following steps of construction preparation, construction measurement, cleaning of the foundation of an outer wall of a seawall, positioning of mixing piles, construction of the mixing piles, construction of fixing assemblies, mounting of connecting assemblies, construction of a wet masonry stone wall, laying of turfs and checks of construction conditions to complete reinforcing construction of the seawall. Under the condition that an original seawall is not dismantled, the outer wall of the original seawall is treated and reinforced, the mixing piles are constructed in a bidirectional mixing mode and are fixedly connected by constructing the fixing assemblies and mounting the connecting assemblies, and a composite foundation is formed by the cement mixing piles and sea mud on the sides of the piles, so that the bearing capacity of the foundation is improved, and settlement and lateral displacement amount of the foundation are reduced. The construction method is easy and feasible to operate, the construction cost is reduced, construction is convenient, the construction efficiency is high, project construction cost can be reduced, and the project construction period can be shortened, so that the project investment benefits are increased.

Description

technical field [0001] The invention relates to a construction method for improving the bearing capacity of seawall surface protection foundation. Background technique [0002] Tidal flat reclamation first requires the construction of seawalls, and soft foundations are common technical difficulties encountered in the construction of seawalls. The nature of soft foundations determines that they need to be reinforced before they can be used as foundations for engineering construction. At present, the soft foundation reinforcement treatment is mainly completed by grouting after riprap, but on the one hand, due to the large length of the seawall, a huge amount of mechanical equipment and earth and stones need to be invested in the soft foundation reinforcement treatment process, resulting in high project cost; on the other hand, The compactness of the seawall is required to be high, and due to the low effective utilization rate of earthwork and slurry thrown into the sea, there ...

Problems solved by technology

In order to reduce the large amount of excavation of earthworks, steel sheet pile cofferdams are also used to construct seawalls. Although this method is faster in construction, it has a great impact on reducing costs and preventing steel sheet piles from becoming through holes after decay. The stability of the seawall usually requires the recycling of sheet piles, however the removal of the sheet piles is very inconvenient
