Combined type environment-friendly inflatable arch cofferdam
The invention discloses a combined type environment-friendly inflatable arch cofferdam capable of being flexibly combined, convenient to assemble and disassemble, environmentally friendly, economical and practical. Two rows of upright posts are connected through straight bars. Auxiliary bridge deck slabs are laid to build a temporary auxiliary bridge. An arc structure is formed by connecting arc bars on the upstream side of the upright posts to be subjected to stress. Installation holes are formed in the middles of the upright posts. Through grooves are formed in one side faces of the upright posts, and installation bars connected with a water blocking curtain can be inserted into the through grooves from top to bottom to install the water blocking curtain. The water blocking curtain is provided with post sleeves and bands. Inflatable cylinders are fixed in the water blocking curtain post sleeves. The inflatable cylinders are provided with wind pipes and bands, and the inflatable cylinders and the water blocking curtain form an elastic water blocking cofferdam body together to block water after the inflatable cylinders are inflated. Falling parts and digging ropes are installed on the other side of the water blocking curtain to make the other side of the water blocking curtain be tiled at the riverbed bottom to be resistant to seepage.
