Features
Culvert rubber balloons with a high compressive strength, good flexibility, strong tightness, and used repeatedly, is a new lower cost bridge construction, water conservancy, is a new lower cost bridge construction,water conservancy, the tunnel project costs, and increase the speed of the amount of pre-engineering concrete products supporting products.
Preparation:
1)the rubber balloons float during joint ramming , it should be fixed in up, down, left, right directions.
2) the method odf pouring concrete is basiclly same as members', pay attention to high frequency inserted or vibrating simultaneously from both sides in case of rubber ballooons make movement, vibrator head position is best not to touch rubber balloons.
