The Tremie Conical Hopper, by Deslauriers, is a specialized tool used for concrete pouring to pour concrete efficiently and controlled, especially in deep or underwater construction. It’s used for the tremie concrete pipe method which is used for pouring concrete below water or where there is a risk of segregation or contamination.
The Tremie Hopper is made of high concrete quality materials such as polyethylene or steel to withstand the construction site and last long. It has a funnel shape with a wide top and narrow bottom, for smooth and continuous flow of concrete.
During the concrete pouring process, the Tremie Hopper is placed vertically above the placement area. The tremie pipe is a long vertical pipe used for underwater concrete placement. The concrete is loaded into the conical hopper which acts as a reservoir, for efficient batch loading and continuous supply of concrete to the tremie concrete placement method point. The narrow bottom ensures a controlled flow, minimizes the risk of segregation or debris entering the concrete after you maintain flow.
One of the biggest advantage of Tremie Hopper is it prevents water from entering the concrete during underwater placement. The hopper maintains a positive pressure at the discharge point, prevents water from entering the flow of concrete and ensures a homogeneous mix.
Also the Tremie Hopper allows for precise placement of concrete in deep foundations, caissons, bridge piers and other submerged or confined structures. The design allows the concrete to be placed in a column without significant free fall, reduces the risk of segregation and maintains the structural integrity of the final product.
In summary the Tremie Hopper by Deslauriers is a specialized tool used for concrete pouring using the tremie concrete pipe method. It provides controlled flow of concrete, prevents water ingress and allows for precise and efficient tremie concrete placement method in difficult construction situations. The use of the Tremie Hopper ensures successful execution of complex projects and quality of concrete structures.
Product Overview
Tremie pipes are a key component in underwater construction and concrete placement. They are used to pour concrete smoothly and controlled in situations where it needs to flow into place without segregation. Our tremie pipes are made of high quality materials, thick polyethylene walls and heavy duty steel chains for extra long life and durability. We have tremie pipes in two sizes 12” dia x 4ft and 8” dia x 4 ft to fit your construction needs.
Key Components and Accessories
Our tremie pipes come with the following components and accessories:
-
Conical hopper: For pouring concrete into the pipe, for smooth and continuous flow.
-
O-ring seal: Prevents water from entering the pipe and mixing with the concrete mix, keeps the concrete intact.
-
Discharge opening: Controls the release of concrete, for precise tremie concrete placement method and minimizes segregation.
-
Foam rubber plug: Seals the bottom of the tremie concrete pipe before pouring concrete, prevents water ingress and clean start.
-
Heavy duty steel chains and brackets: For added durability and support, to keep the tremie concrete pipe in place during pouring.
-
Lifting cap and suspension jig: For easy handling and placement of the tremie pipe, for more efficient and safe process.
Applications and Uses
Tremie pipes have many applications in the construction industry, especially in underwater construction and concrete placement. Some of the common applications are:
-
Underwater foundations: For bridge piers, offshore platforms and other underwater structures where precise concrete placement is required.
-
Diaphragm walls and piles: For deep foundation construction, tunneling and subway stations for stable and durable structures.
-
Complex structures: For tunnels, subway stations and other complex structures where access is limited and precise concrete placement is required.
-
Underwater concrete placement: For seawalls, breakwaters and other offshore structures, to place the concrete accurately and efficiently.
Benefits and Advantages
Using tremie pipes has the following benefits and advantages:
-
Continuous flow: For smooth and controlled concrete placement, minimizes interruptions and maintains the pour quality.
-
Prevents segregation and washout: Keeps the concrete mix intact and strong by preventing the separation of aggregates and cement.
-
Versatility and depth: Can deliver concrete to great depths and complex structures, for many types of construction projects.
-
More reliable strength: Produces stronger placed concrete, for durability and stability of the final structure.
-
Gravity feed: For continuous flow of concrete, minimizes segregation and washout and ensures consistent and homogeneous mix.
Safety and Best Practice
To pour fresh concrete safely with tremie pipes follow these best practices:
-
Batch control: Introduce each fresh concrete batch quickly to maintain continuous flow and prevent early set, for consistent and high quality pour.
-
Equipment maintenance: Check and maintain tremie pipes and accessories regularly to ensure they are clear of blockages and damage, to minimize interruptions and ensure safety.
-
Proper training: Operators should be trained to operate the equipment and understand the concrete flow dynamics through tremie pipes, for efficient and safe operation.
-
Flow: Keep the flow continuous to prevent segregation and washout, to keep the placed concrete intact and strong.
-
Upper surface: Keep the tremie pipe below the upper surface of the rising concrete level to maintain a seal and prevent water from mixing with cement, for homogeneous mix.
-
Freshly placed concrete: Don’t disturb or vibrate placed fresh concrete excessively which can cause segregation or washout, for stability and strength of the final structure.
