What Is Caisson Foundation | Types of Caisson Foundation | Advantage, Disadvantage, Application, & Construction of Caisson

Caisson Foundation

Caisson foundations, also known as pier foundations, are prefabricated hollow substructures designed to be constructed on or near the surface of the ground, sunk to the desired depth and then filled with concrete, thus ultimately becoming an integral part of the permanent structure.

What Is Concrete Caisson Foundation?

Concrete caisson foundations, also known as concrete pier foundations, are prefabricated hollow substructures designed to be constructed on or near the surface of the ground, sunk to the desired depth and then filled with concrete, thus ultimately becoming an integral part of the permanent structure.

Caisson Footing

A caisson foundation also called as pier foundation is a watertight retaining structure used as a bridge pier, in the construction of a concrete dam, or for the repair of ships.

Caisson Foundation

Caisson foundations is a form of deep foundation that is built above ground level, then submerged to the required level by excavating or dredging material within the caisson; Caisson (sometimes called “piers”) are made by auguring a deep hole in the ground then filled with concrete, it is also known as pier foundation.

Caisson Construction

In geotechnical engineering, a caisson is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair.

Caisson Construction Method

It is a form of deep foundation which are constructed above ground level, then sunk to the required level by excavating or dredging material from within the caisson. Caissons (also sometimes called “piers”) are created by auguring a deep hole into the ground, and then filling it with concrete.

Caisson Structure

A caisson is a box-like structure commonly used in civil engineering projects where work is being carried out in areas submerged in water. Such projects might include: Bridge piers. Abutments in lakes and rivers.

Steel Caissons

A steel caisson is a large diameter steel pipe that is a watertight chamber used in underground consttuction to hold back water and soil. Typically it is filled with rebar and concrete. Arntzen Corporation produces quality large diameter caissons for drilling foundation contractors.

How Does a Caisson Work?

Workers, called sandhogs, move mud and rock debris (called muck) from the edge of the workspace to a water-filled pit, connected by a tube (called the muck tube) to the surface. When the caisson hits bedrock, the sandhogs exit through the airlock and fill the box with concrete, forming a solid foundation pier.

Caisson Foundation Vs. Other Deep Foundation Methods

Caissons are sturdy, watertight structures made of wood, steel, or reinforced concrete. They are built above ground level and then sunk into the ground. A pile foundation is a deep foundation that uses vertical timber, concrete, or steel to support loads at a low level.

Pros and Cons of Using Caisson Foundations

Advantages & Disadvantages of Caisson Foundation

• Caissons are economic.
• It is environment-friendly.
• It is easily adaptable to varying underwater soil conditions.
• Caisson has high horizontal and lateral loading capacity.
• Minimum handling equipment is required for placement of reinforcement cage.

Types of Caisson Foundations for High-Rise Buildings

To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is preferred, a stable, hard mud is sometimes used when bedrock is too deep. The four main types of caisson are box caisson, open caisson, pneumatic caisson and monolithic caisson.

Advantages of Using Caisson Foundations in Construction

There are slightly less sound pollution and reduced vibration. It is easily adaptable to varying underwater soil conditions. Caisson has high horizontal and lateral loading capacity. Minimum handling equipment is required for placement of reinforcement cage.

Advantages of Caisson Foundations Vs. Traditional Foundations

Caissons provide the support necessary to distribute weight evenly and prevent any settling that might occur due to soil fluctuations. They are sturdier than traditional foundation pads and provide greater strength for both axial and lateral loads.

Caissons Construction

What is Caisson Construction? Caisson construction is a foundation used in deep water or soft soil. It involves a series of large, watertight cylinders that are sunk into the ground and filled with concrete. The base provides a stable foundation for structures built on top of it.

What Is a Caisson in Construction?

Caisson construction is a foundation used in deep water or soft soil. It involves a series of large, watertight cylinders that are sunk into the ground and filled with concrete. The base provides a stable foundation for structures built on top of it. Bridges, docks, and large structures often use caisson construction.

What Are the Types of Caissons That Can Be Used as a Foundation?

There are several types of caisson foundation.

• Box Caissons.
• Excavated Caissons.
• Floating Caissons.
• Open Caissons.
• Pneumatic Caissons.
• Compressed Air Caissons.
• Monolithic Caissons.

What Is the Purpose of a Caisson?

In geotechnical engineering, a caisson (/ˈkeɪsən/ or /ˈkeɪsɒn/; borrowed from French caisson, from Italian cassone, meaning large box, an augmentative of cassa) is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair …

Piles and Caissons Are Examples of What Kind of Foundations?

Deep foundation types

• Pile foundations. A pile foundation consists of a long cylinder created from concrete or another type of strong material. …
• Drilled shafts. Drilled shafts, sometimes referred to as caissons, are deep foundations that work similarly to pile foundations but offer a higher level of load capacity.

Caisson Sinking Method

The caisson sinking method is one way to construct underground concrete structures, such as bridge piers, intake structures, pump houses and dumper pits, in soils with a high water table. In this method, a caisson is constructed on the unexcavated site, with the caisson comprising only the walls of the final structure.

Installing Caissons

In Caisson installation, the wet well base is placed at or just below grade, and the hole is excavated through the wet well itself. As soil and earth is removed through the open wet well, the structure sinks into the ground, often with additional ballast and/or lubrication.

Caisson Foundation Cost

Grade beam and caisson foundation repair is expensive. The caissons themselves are a good $10,000 each. If you have 3 caissons, put in, that’s a minimum of 30k.
