River blocking cofferdam with adjustable water passing switch and construction method
The invention discloses a river blocking cofferdam with an adjustable water passing switch and a construction method. The river blocking cofferdam is characterized in that two rows of longitudinal lock catch type steel pipe piles stretch across a river channel, and the rear portion of each row of longitudinal lock catch type steel pipe piles is fixed to be a first enclosing purlin through at least one layer of double-spliced channel steel; the two rows of transverse lock catch type steel pipe piles are arranged between the two columns of longitudinal lock catch type steel pipe piles, and the two rows of transverse lock catch type steel pipe piles are connected through the T-shaped lock catch type steel pipe piles at the crossed points respectively, so that a cofferdam water passing section is defined. The rear part of each row of transverse lock catch type steel pipe piles is fixed by at least one layer of double-spliced channel steel to form a second enclosing purlin; the two rows of longitudinal lock catch type steel pipe piles are connected through a plurality of horizontal pull rods in a penetrating mode. Each row of transverse lock catch type steel pipe piles is connected to one column of longitudinal lock catch type steel pipe piles at the adjacent end through two inclined pull rods; and the weir body is filled with the backfill.
本发明公开一种过水开关可调的拦河围堰及施工方法，包括：两列纵向锁扣式钢管桩横跨河道，每列所述纵向锁扣式钢管桩的后方以至少一层双拼槽钢固定为第一围檩；两排横向锁扣式钢管桩设于所述两列纵向锁扣式钢管桩之间，且在交叉的点上分别以一T型锁扣式钢管桩连接，以此围成一围堰过水段；每一排所述横向锁扣式钢管桩的后方以至少一层所述双拼槽钢固定为第二围檩；两列纵向锁扣式钢管桩以若干水平拉杆穿设连接；每一排所述横向锁扣式钢管桩以两根斜向拉杆连接于相邻端的一列所述纵向锁扣式钢管桩上；回填土填充于堰体内。
