Sealing process method of rubber movable cofferdam
The invention provides a sealing process method of a rubber movable cofferdam. The sealing process method of the rubber movable cofferdam comprises the following steps that firstly, a bottom turnoveradhesive tape is added in the bottom sealing process, so that the bonding strength of lap jointing among dam bags is increased, and the problem of cracking of the lap joint position can be prevented through the structure when the upstream water pressure of the cofferdam is higher; secondly, due to the fact that a sheet-shaped tail is reserved in the structural design of the rubber cofferdam, the cofferdam can be fixed through the sheet-shaped tail in the field using process; and finally, an inwards-folded adhesive tape is additionally arranged on a side face seal, the situation that the side edge of an edge seal is torn due to large pressure in the cofferdam is avoided, and meanwhile an outer sealing adhesive tape is additionally arranged and wraps the outer side, so that the strength of the part is higher.
本发明提供了一种橡胶活动围堰的封口工艺方法，首先，在底部封口过程中增加了底部翻折胶布，增加了坝袋之间搭接的粘合强度，在围堰上游水压较大时可通过此结构防止搭接位置的开裂问题；其次，由于橡胶围堰的结构设计中预留了片状尾巴，所以在现场使用过程中可以通过该部位将围堰固定住；最后，侧面封口增设了向内翻折胶布，避免出现围堰内由于压力大导致边部封口侧边撕裂的情况，同时增设了外部封口胶布，包裹于外侧使得该部位强度更高。
