Combined support pile and construction method thereof
The invention discloses a combined support pile and a construction method thereof. The combined support pile comprises a prefabricated prestressed concrete special-shaped support pile, a prefabricated integral connecting piece and two steel sheet piles; flanges are arranged on the two sides of the prefabricated prestressed concrete special-shaped support pile; the prefabricated integral connecting piece is arranged at the top of the prefabricated prestressed concrete special-shaped support pile and comprises a structural steel sheet; the structural steel sheet is tightly attached to the side face of the prefabricated prestressed concrete special-shaped support pile; the structural steel sheet is provided with connecting parts located on the outer sides of the flanges; the two steel sheet piles are arranged on the two sides of the prefabricated prestressed concrete special-shaped support pile; each steel sheet pile comprises flat steel and two connecting steel pieces located on the two sides of the flat steel respectively; the two connecting steel pieces are each provided with a groove; the two connecting parts and the two flanges are inserted into the grooves of the connecting steel pieces of the two steel sheet piles; and the flanges, the connecting parts and the connecting steel pieces which are close to each other are fixedly connected. According to the invention, the soil squeezing effect and the use amount of support piles can be reduced.
一种组合支护桩及其施工方法。其中，该组合支护桩包括预制预应力混凝土异形支护桩、预制整体连接件和两个钢板桩，预制预应力混凝土异形支护桩的两侧均设置有翼缘；预制整体连接件设置在预制预应力混凝土异形支护桩的顶部，且预制整体连接件包括结构钢片，结构钢片紧贴预制预应力混凝土异形支护桩的侧面，结构钢片具有位于翼缘外侧的连接部；两个钢板桩设置在预制预应力混凝土异形支护桩的两侧，钢板桩包括平板钢以及分别位于平板钢两侧的两个连接钢件，两个连接钢件均设置有凹槽；两个连接部和两个翼缘均分别插入到两个钢板桩的连接钢件的凹槽中，且彼此靠近的翼缘、连接部和连接钢件固定相连。本发明可以减少挤土效应和支护桩的使用量。
