Steel sheet pile and concrete wall combined cofferdam structure and construction method
A technology of combining cofferdam and concrete wall, applied in sheet pile wall, infrastructure engineering, construction, etc., can solve the problem that cofferdam entry, water stop, stress, labor cost of concrete retaining wall, high material cost, etc. can not be effectively solved. The construction of concrete retaining walls takes a long time to achieve the effect of reducing the difficulty of construction and demolition, reducing material costs, and preventing deformation or damage

Problems solved by technology
However, in areas with large sloping bare rock and deep coverage on the bank, when the foundation is in the bare rock and deep coverage of large sloping bedrock, the above surrounding water structure is affected by topographical conditions, and cannot effectively solve the problems of cofferdam entry, water stop, and force bearing. The problem brings great difficulty to the foundation construction in water
[0003] In the prior art, for the case where the foundation is in the bare rock and deep coverage of the large-inclined bedrock in the deep-covered area of the large-inclined bedrock on the bank, multiple concrete structures are usually built around the large-inclined bedrock and the water. The retaining wall forms a cofferdam structure, but the construction of the concrete retaining wall takes a long time, and it is difficult to dismantle it later, resulting in high labor and material costs for the concrete retaining wall, and the efficiency of cofferdam construction is poor

The invention relates to the technical field of underwater foundation construction, in particular to a steel sheet pile and concrete wall combined cofferdam structure and a construction method. The steel sheet pile and concrete wall combined cofferdam structure comprises a wall body assembly built on bedrock on a shore, the wall body assembly comprises a first wall body and a second wall body and a steel sheet pile assembly. The first wall body and the second wall body are oppositely arranged, and a first supporting rod is arranged between the first wall body and the second wall body; at least part of the steel sheet pile assembly is located in water, one end of the steel sheet pile assembly is arranged in the first wall body, and the other end of the steel sheet pile assembly is arranged in the second wall body. According to the steel sheet pile and concrete wall combined cofferdam structure, the cofferdam structure is formed by arranging the wall body assembly, the steel sheet pile assembly and the first supporting rod arranged between the first wall body and the second wall body, the structural strength of the wall body assembly is improved, and therefore the overall structural strength of the cofferdam structure is improved, and the steel sheet pile and concrete wall combined cofferdam structure is simple in structure. The construction and dismantling difficulty of the cofferdam structure is reduced, the construction efficiency of the cofferdam structure is effectively improved, and the cost is effectively reduced.
Description
technical field [0001] The present disclosure relates to the technical field of underwater foundation construction, in particular to a combined cofferdam structure of a steel sheet pile and a concrete wall and a construction method. Background technique [0002] In the construction of foundations in water, it is usually necessary to build temporary or permanent cofferdams to realize foundation construction operations, which mainly include steel sheet piles, bottomed or bottomless steel casings, locking steel pipe piles, double-row steel pipe piles, weir core fill, soil Cofferdams, etc. However, in the area with deep coverage of heavily sloping bare rock on the shore, when the foundation is in the bare rock and deep coverage area of highly sloping bedrock, the above water enclosure structure is affected by topographical conditions and cannot effectively solve the problems of cofferdam entry, water stop, stress, etc. It brings great difficulties to the construction of the f...
