Sea wall structure with double-row steel sheet piles

Abstract

The invention relates to a sea wall structure with double-row steel sheet piles in complex foundation sea reclamation engineering. The sea wall structure with the double-row steel sheet piles comprises the two steel sheet piles, concrete cap beams, a pull rod, two stone template layers, a wave blocking wall and medium coarse sand, wherein the front and rear two steel sheet piles are connected through the pull rod, the front and rear two steel sheet piles are tensioned by the pull rod, the tops of the two steel sheet piles are cast in situ with the concrete cap beams, the two stone template layers are arranged between the concrete cap beams, the wave blocking wall is arranged on the outer side of the rear steel sheet pile, the outer side of the front steel sheet pile is backfilled with themedium coarse sand, and back pressure is carried out by backfilling with the medium coarse sand. The sea wall structure with the double-row steel sheet piles can safely and reliably prevent a bank slope from losing stability and sliding, and a cofferdam body has a small occupied area; and high retaining strength, good erosion resistance and seepage resistance, high construction speed, less raw material consumption, environmental protection principle, simple structure and convenient construction are achieved.

Description

technical field [0001] The invention relates to the design field of complex foundation reclamation engineering, in particular to a seawall structure with double-row steel sheet piles which can adapt to complex foundations. Background technique [0002] The stability of the seawall structure is an important sub-item of the reclamation project structure, especially in the reclamation project with complex foundations, which is related to the safety of the entire reclamation project structure. At present, the seawall structure in most reclamation projects mainly adopts a slope-type earth-rock embankment structure. The earth-rock embankment structure needs to use a large amount of replacement materials to improve the soil index under the embankment structure. The project cost is relatively high, and the construction The speed is slow, the construction cost is high, and the construction quality is difficult to guarantee. In addition, affected by the ebb and flow of the tide and th...

At present, the seawall structure in most reclamation projects mainly adopts a slope-type earth-rock embankment structure. The earth-rock embankment structure needs to use a large amount of replacement materials to improve the soil index under the embankment structure. The project cost is relatively high, and the construction The speed is slow, the construction cost is high, and the construction quality is difficult to guarantee. In addition, affected by the ebb and flow of the tide and the erosion of the waves, the slope-type earth-rock embankment structure is often damaged and the entire structure becomes unstable. Such accidents are not uncommon in the industry. of
