Abstract

This application relates to a steel sheet pile cofferdam, which includes several pile bodies, the top of the pile body is provided with movable grooves along the length direction, and the side wall of the pile body facing the outside of the cofferdam is provided with several movable grooves at intervals along the length direction. connected connecting holes, the inner wall of the connecting hole is plugged with a guide slide; the inner wall of the movable groove is provided with a number of ejection components corresponding to the connecting holes at intervals along the length direction; the ejection assembly includes a ejector The base and the ejection block, the ejection base is fixedly connected on the inner wall of the movable groove, the ejection block is slidably arranged on the ejection base along the opening direction of the connection hole, and several ejection blocks correspond to the connection holes one by one , one end of the ejector block can slide into the corresponding connection hole; a drive plate is provided on the inner wall of the movable groove, and the drive plate can drive all the ejector blocks to slide and make the ejector block push the guide slide plate to the pile body Outside; this application has the effect of being convenient to pull out the pile body from the soil layer.

Description

technical field [0001] The present application relates to the field of cofferdams, in particular to a steel sheet pile cofferdam. Background technique [0002] Cofferdam is a maintenance structure used in water conservancy projects. It has the functions of preventing water seepage and soil seepage, so as to facilitate drainage, digging foundation pits and building buildings inside the cofferdam. [0003] The current steel sheet pile cofferdam is generally formed by splicing multiple steel sheet piles, and the steel sheet piles are sequentially driven into the soil layer during use to form a cofferdam structure. After the construction of the cofferdam, the steel sheet piles need to be pulled out from the soil layer for reuse. Due to geological reasons, when the steel sheet piles are driven into the dense sandy soil layer, due to the viscosity of the soil and the impact of the soil layer on the steel sheet piles If the clamping force is high, it is easy to make the steel shee...
