Culvert Rubber Balloon Rubber Inflatable Core Mold for Bridge and Tunnel Formwork

Product Description

Product Description

The is an efficient pipeline blocking device designed for temporary or permanent sealing of culverts, drainage pipes, and similar structures. Made from high-strength, highly elastic specialty rubber, it forms a reliable seal by expanding to closely fit the inner walls of the culvert, effectively blocking the passage of water, mud, and other impurities. This ensures smooth operation of construction, inspection, or maintenance work. The plug is easy to operate, with quick inflation allowing for fast blocking and significantly improved work efficiency.

The boasts exceptional adaptability and reusability. Its flexible rubber material conforms to various culvert shapes and sizes, be it circular, arched, or rectangular, ensuring a reliable seal. After use, the plug can be quickly removed via deflation without damaging or leaving residues on the culvert walls, preserving the culvert's integrity. With its efficient, convenient, and reliable features, it has become an essential tool for culvert projects and is widely used in scenarios requiring pipeline blocking.

Feature
*Excellent Sealing Performance: Inflates to form a tight bond with culvert walls, achieving a leak-proof seal that effectively blocks water and impurities.
*Strong Adaptability: The flexible rubber material conforms to various culvert shapes and sizes, ensuring a reliable seal in different configurations.
*Easy Operation: Inflation and deflation are quick and simple, requiring only a dedicated air pump and no special tools.
*High Reusability: Made from premium rubber that is wear-resistant, pressure-resistant, and aging-resistant, allowing for multiple uses and cost reduction.
*Non-damaging to Pipelines: Adjustable inflation pressure prevents damage to culvert walls during operation, with no residues left upon removal.
*Portability: Compact and lightweight for easy transport and use across different worksites.

Installation

Requirements for the for hollow core precast beams:

    *When installing the , the length specifications of the hollow core precast beams are usually 8 m, 10 m, 13 m, 16 m, 20 m, 25 m, and 30 m; lengths exceeding 30 m are generally not designed as hollow core beams.
    *For below 13 m in length, the inner is generally made of rubber; for culvert balloons above 16 m in length, there is more flexibility in the choice of inner culvert balloons, which can be rubber, wood, or steel.
    *During the construction process, the is placed inside the rebar cage, inflated with compressed air to form the desired cavity shape, and withstands the pressure during concrete pouring. After use, it can be deflated and removed from the cavity, allowing for multiple reuse.

Product Details

are widely used in:
*Culvert Repair and Reconstruction: Blocks damaged culvert sections for quick repairs and restoration of drainage functions.
*Drainage Pipe Clearing and Inspection: Seals drainage pipes for clearing or inspection tasks, such as water-tightness and flow tests.
*Wastewater Treatment and Pipeline Maintenance: Temporarily seals pipelines during wastewater treatment plant and sewer maintenance to prevent leaks.
*Construction and Foundation Drainage: Blocks groundwater and drainage pipes during foundation work to prevent flooding and ensure construction safety.
*Water Conservancy Projects and Flood Control: Temporarily seals channels and gate in water conservancy projects and rapidly blocks breaches in flood control for damage mitigation.
*Municipal Engineering and Pipeline Repair: Facilitates quick pipeline blocking during municipal repair tasks to minimize disruptions to urban traffic and residents.
