The invention provides a corrugated steel sheet pile wall enclosure structure and a construction method. The enclosure structure comprises a steel sheet pile unit, and the steel sheet pile unit comprises a first corrugated steel sheet, a second corrugated steel sheet, a pulling and connecting piece, an auxiliary corrugated steel sheet and a concrete wallboard; the first corrugated steel plate and the second corrugated steel plate are arranged in parallel, the first corrugated steel plate and the second corrugated steel plate are formed by splicing single corrugated steel bodies, and the adjacent single corrugated steel bodies are connected through first fastening bolts. The corrugated steel plates and the concrete wallboards are integrated to form the steel plate pile units, and high structural strength is achieved; the corrugated steel plate has high durability, and can be used as a permanent maintenance structure for a long time after being combined with the concrete wallboard and pressed into a designed position; the corrugated steel plate is formed by splicing the corrugated steel single bodies, the length and the width of the corrugated steel plate can be adjusted according to actual requirements, and therefore the length and the width of the steel plate pile unit are changed to adapt to different excavation maintenance depth and length requirements.

本发明提供一种波纹钢板桩墙围护结构和施工方法，围护结构包括钢板桩单元，所述钢板桩单元包括第一波纹钢板、第二波纹钢板、拉接件、辅助波纹钢板和混凝土墙板；所述第一波纹钢板和第二波纹钢板平行设置，所述第一波纹钢板和第二波纹钢板均由波纹钢单体拼接而成，相邻所述波纹钢单体之间通过第一紧固螺栓连接。本发明将波纹钢板与混凝土墙板一体形成钢板桩单元，具有较高的结构强度；波纹钢板本身具有较高的耐久性，与混凝土墙板结合压入设计位置后可以作为永久维护结构长期使用；波纹钢板由波纹钢单体拼装而成，可以根据实际需要来调整波纹钢板的长宽，从而改变钢板桩单元的长宽，以适应不同开挖维护深度和长度需求。
