Composite embankment body ecological seawall structure on soft soil foundation and construction method of composite embankment body ecological seawall structure

Abstract

The invention discloses a composite embankment body ecological seawall structure on a soft soil foundation and a construction method of the composite embankment body ecological seawall structure. The composite embankment body ecological seawall structure comprises a seawall foundation, a composite embankment body structure, a protection structure and a greening structure. The composite dike body structure comprises lower dike core stones which are thrown and filled on a seawall foundation, inverted filter structures which are thrown and filled towards a land area along the side slope, close to the shore, of the lower dike core stones, dike core sand or dike subsoil which is thrown and filled towards the land area along the side slope, close to the shore, of the inverted filter structures, and upper dike core stones which are thrown and filled at the tops of the lower dike core stones, the inverted filter structures and the dike core sand or the dike subsoil. An anti-seepage wall is arranged in the dike core sand or the dike core soil; the greening structure comprises cultivating and planting soil and a three-dimensional grass planting mattress, wherein the cultivating and planting soil is laid and filled towards the land along the side slope, close to the bank, of the upper dike core stone, and the three-dimensional grass planting mattress is laid on the top face of the cultivating and planting soil. The construction difficulty of the anti-seepage wall is greatly reduced, the work efficiency and quality are improved, the stability of the seawall on the soft soil foundation is ensured, the settlement amount of the seawall is greatly reduced, and it is ensured that the anti-seepage wall is not cracked due to settlement of the seawall body.

Description

technical field [0001] The invention relates to the technical fields of water transportation engineering, water conservancy engineering, river management engineering and the like. More specifically, the present invention relates to a composite embankment body ecological seawall structure on a soft soil foundation and a construction method thereof. Background technique [0002] In the traditional construction of seawall structures, the foundation trenches are generally excavated and replaced, and then the embankment core stones are thrown and filled, and then the protective blocks are installed, and the wave retaining walls and pavement structures are poured. The construction method of this seawall structure has the following disadvantages: first, the amount of excavation of the foundation trench is large, which has a greater impact on the ecological environment of the surrounding waters, and also affects the safety of adjacent buildings; second, the amount of block stone is ...

AI Technical Summary

Problems solved by technology

The construction method of this seawall structure has the following disadvantages: first, the excavation volume of the foundation trench is large, which has a great impact on the ecological environment of the surrounding waters, and will also affect the safety of adjacent buildings; second, the amount of block stones is relatively large. Large, the embankment is all composed of block stones, not only the demand for stone materials is large, the construction strength of the riprap is high, and the project cost is high, but the construction of the anti-seepage wall in the riprap embankment is difficult, the work efficiency is low, the quality is difficult to guarantee, and the cost is high; Third, the sea side of the seawall is connected to the land side, and the seawater is easy to flood the land area; fourth, the seawall is completely composed of block stones and concrete structures, which does not meet the requirements of ecological seawalls
