Embodiment 1

[0013] The caisson structure used for seawalls on soft soil foundations includes a box body and a retaining wall 10, the box body is divided into a caisson 1 20 and a caisson 2 9, the caisson 2 9 is arranged on the caisson 1 20, and the retaining wall 10 is arranged on the On the right side of caisson 2 9, the function of the retaining wall 10 is to block the soil and prevent the soil on the right side from squeezing the caisson structure; There are connecting pipes 21 connected to each other, and the whole box body is made of reinforced concrete, wherein: caisson 1 20 is an open bottom structure, so caisson 1 20 is set on soft soil, and its interior is soft soil, and caisson 2 9 is sealed Closed structure, the right side top of caisson one 20 is provided with drainage hole 22, when caisson two 9 is installed on caisson one 20, the water in the soft soil is squeezed out by pressure, just discharges along drainage hole 22. The top left side of caisson two 9 is provided with wat...

Abstract

The invention relates to a caisson structure for a soft soil foundation sea wall. The caisson structure for the soft soil foundation sea wall comprises a caisson I, a caisson II and a retaining wall forming a structure unit, wherein the caisson II is arranged on the caisson I; the caisson I and the caisson II are casted integrally; and the retaining wall is arranged on the right side of the caisson II. The caisson structure for the soft soil foundation sea wall is characterized in that a water pump is arranged on the left side of the top part of the caisson II; one side of the water pump is connected with a water pipe I so as to lead into a sea; the other side of the water pump is connected with a water pipe II so as to lead into the caisson II; the water pipe II extends to the bottom partof the left side of the caisson II; an inclined slope structure is arranged on the bottom part of the caisson II; and a cross rod is arranged above the inclined slope structure. The caisson structurefor the soft soil foundation sea wall provided by the invention has the beneficial effects that by utilizing a reasonable structure design and adopting a thin-wall caisson structure, the caisson structure unit and foundation soil are similar in density, so that the sea wall can be directly constructed without the need for foundation treatment, the cost of foundation treatment is reduced, the differential settlement of the sea wall is reduced, and the caisson structure for the soft soil foundation sea wall is suitable to be popularized and used.

Description

technical field [0001] The invention relates to a caisson structure used for seawalls on soft ground, and belongs to the technical field of marine engineering. Background technique [0002] Soft soil refers to fine-grained soil with high natural water content, large void ratio, high compressibility, and low shear strength deposited in coastal areas, lakes, valleys, and river beaches. It has high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex layered distribution of soil layers, and The physical and mechanical properties are quite different among them. [0003] When building seawalls on soft soil foundations, foundation treatment generally takes up a lot of cost and takes a lot of time. Contents of the invention [0004] The present invention overcomes the problems existing in the prior art, and propose...
