Bidirectional water stop side check seal

Abstract

The invention relates to a bidirectional water stop side check seal. The bidirectional water stop side check seal is provided with a Y-shaped side check seal body. The Y-shaped side check seal body is provided with a fixing plate part making contact with a steel gate. Fixing holes spaced by a certain standard distance are reserved in the fixing plate part. The Y-shaped side check seal body is provided with an inner water stop sheet bar and an outer water stop sheet bar. The outer surface of the top end of the inner water stop sheet bar and the outer surface of the top end of the outer water stop sheet bar are provided with self-sealing rubber soft layers. The Y-shaped side check seal body is internally provided with an inner steel frame. The inner steel frame is wrapped with a rubber sealing layer. The outer side of the inner steel frame and the rubber sealing layer are bonded together through a polyisocyanate adhesive agent. The bidirectional water stop side check seal is suitable for gate sealing and has the advantages of being scientific in design, reasonable in structure, low in cost, easy to operate, good in water stop effect, resistant to aging and long in service life.

Description

technical field [0001] The invention belongs to a sealing member, in particular to a sealing rubber strip on a water conservancy gate. Background technique [0002] The two-way water-stop side seal is the key component of the pneumatic shield gate system. It is located at the joint between the end of the gate and the gate pier. The gate is connected to the main anchor bolt of the foundation through the hinge cover plate, and it is realized by inflating and deflating the air bag. As the gate rises and falls, as the gate slowly rises from the low point, the water pressure on the joints between the gate and the gate pier gradually increases. The wheel-rail method adopted by the traditional gate will not stop when the water level exceeds 3 meters. , the leakage rate will be difficult to guarantee; and because there is no two-way water-stop effect, when the downstream water level rises, it will flow back to the upstream; the traditional gate using wheel rails, its force is concen...

[0002] The two-way water-stop side seal is the key component of the pneumatic shield gate system. It is located at the joint between the end of the gate and the gate pier. The gate is connected to the main anchor bolt of the foundation through the hinge cover plate, and it is realized by inflating and deflating the air bag. As the gate rises and falls, as the gate slowly rises from the low point, the water pressure on the joints between the gate and the gate pier gradually increases. The wheel-rail method adopted by the traditional gate will not stop when the water level exceeds 3 meters. , the leakage rate will be difficult to guarantee; and because there is no two-way water-stop effect, when the downstream water level rises, it will flow back to the upstream; the traditional gate using wheel rails, its force is concentrated on the guide wheels at both ends of the gate, and the stress condition is poor, and The installation requirements are high, and the error control is strict. There are many disadvantages and inconveniences in the design and installation work.
