Abstract

The invention discloses an improved ultra-long steel plate pile and a foundation pit cofferdam thereof. The improved ultra-long steel plate pile comprise a pile head end splice steel plate and a pilebody section splice steel plate and is characterized in that a reinforced pile head is arranged at the bottom of the pile head end splice steel plate, a splice inserting threaded opening is formed inthe upper portion of the pile head end splice steel plate, at least two lock catches are arranged on the upper portion of the pile head end splice steel plate, and a waterstop is arranged at the top of the pile head end splice steel plate. The improved ultra-long steel plate pile and the foundation pit cofferdam thereof have the advantages that the inserting piling speed and the pile forming probability of the steel plate pile can be effectively increased by using the improved steel plate pile head, the steel plate pile can be more effectively applied to construction requirements under the geological condition in a deep water environment after the appearance is improved and the strength is reinforced, and meanwhile, the recycling service life of the steel plate pile can be prolonged.

Description

technical field [0001] The invention relates to an improved super-long steel sheet pile and a foundation pit cofferdam. Background technique [0002] Most of the literature on the construction technology of steel sheet pile cofferdams are conventional steel sheet pile construction techniques, and there are few records on the construction of super-long steel sheet piles. The problems of subsidence and high risk have always been obstacles to the use of ultra-long steel sheet piles under special geological conditions. Therefore, the research on the construction technology of super-long steel sheet piles under special geological conditions can not only improve the construction level of urban bridges, but also ensure the safety, applicability and economy of urban bridges, improve work efficiency and speed up the construction progress, and play a positive role in the development of urban bridge construction technology. effect. SUMMARY OF THE INVENTION [0003] The purpose of t...
