Embodiment 1

[0022] figure 1 , figure 2 , image 3 In the shown embodiment, a composite seawall includes seawall barrel piles, and a row of vertical rigid cast-in-situ 1500mm large-diameter ribbed piles exposed to the sea level C are driven into the original shoal mud 50 on the outer shallow sea side A. Seawall barrel piles 10, the reinforcement cage is installed in the annular body of the seawall barrel piles 10 with ribs, and the seawall barrel piles 10 with large diameters are conjoined and interlocked. The side B carries out blow filling and raises the blow packing 30 above sea level, and the blow packing 30 comprises the clay layer 31 at the bottom, the riprap layer 33 at the top and the silt layer 32 in the middle part; A row of 1000mm cast-in-place large-diameter plain-tube seawall piles 20, no reinforcement cage is installed in the annular body of the diameter-diameter plain-tube seawall piles 20, and multiple rows of cast-in-place large-diameter plain-tube seawall piles 20 are...

Embodiment 2

[0024] There is a gap between the large-diameter ribbed seawall piles 10, the gap is provided with a sealing board, and the method of adding a board is used to seal the gap, and the rest is the same as that of Embodiment 1.

Embodiment 3

[0026] There is a gap between the large-diameter ribbed seawall piles 10, the gap is provided with a sealed rockfill, and the gap is sealed with a rockfill method, and the rest are the same as in Embodiment 1.

Abstract

The invention discloses a combined type seawall which comprises seawall tubular piles. A row of vertical rigid cast-in-situ large-diameter ribbed seawall tubular piles (10) exposed out of sea level (C) are piled on an outer shallow sea side (A); hydraulic fillers (30) higher than the sea level are filled in the inner sea side (B) of the large-diameter ribbed seawall tubular piles; a plurality of rows of cast-in-situ large-diameter plain barrel seawall tubular piles (20) are piled on the inner sea side (B); the hydraulic fillers (30) higher than the sea level are filled in the areas of rows of plain barrel seawall tubular piles; riprap solid bases (40) of the plain barrel seawall tubular piles and the ribbed seawall tubular piles are arranged above the hydraulic fillers; and the construction method of firstly piling a row of vertical cast-in-situ large-diameter ribbed seawall tubular piles on the shallow sea side, then hydraulically filling in the inner side and then carrying out combined type bases construction on the filled inner side is adopted. The invention has the advantages of small stone consumption, small land occupation area of seawall body, high land utilization rate, short construction period, advanced construction process, obvious environmental protection benefit and the like.

Description

technical field [0001] The invention relates to a seawall structure, in particular to a seawall structure suitable for obtaining land from sea flats in coastal areas. Background technique [0002] With the continuous deepening of my country's reform and opening up, my country's economic construction has developed steadily and rapidly, especially the economic development of coastal areas has achieved world-renowned achievements. As we all know, land resources are an important basis for ensuring economic development. With the rapid development of economy, construction land is becoming increasingly scarce, and it has become a consensus in coastal economically developed areas to ask for land from tidal flats. However, the traditional drainage inserting method rockfill embankment and the blasting and silting method rockfill embankment used in previous land reclamation projects require a large amount of mining and use of stone materials, which have adverse effects on the surroundi...
