Description

Anti-collapse dam bag

Technical Field

The utility model relates to the technical field of rubber dams, in particular to a dam bag capable of resisting a collapse shoulder.

Background

The rubber dam adopts the working principle that an anchoring part (which is in a rectangular shape and is divided) is pre-embedded on a concrete dam foundation, and during installation, a hole is punched in the anchoring part at the edge of the rubber dam and is sleeved on the pre-embedded anchoring part to be fixed, so that a closed semi-elliptical space is formed. Then water is injected into the dam through a water filling pipeline on the dam foundation to lift, and the position of the dam head is tightly attached to the concrete side walls at the two ends, so that the water storage effect is achieved. Because of the similar shape of the pillow, the pillow-type rubber dam is commonly called in the industry.

In actual operation, when the dam head of the pillow-type rubber dam slowly rises, friction is large because the dam head is tightly attached to the concrete side walls at the two ends. Often resulting in overlapping and wrinkling between the dam head and the side wall. The dam head is insufficiently and incompletely lifted, namely the phenomenon of 'shoulder collapse' commonly known in the industry is caused. The direct viewing phenomenon is that the positions of the side walls at the two ends cannot reach the designed height when the dam bag runs, the landscape effect is influenced, and the designed water storage height cannot be reached.

In view of this, we propose a dam bag that resists collapse.
