Design Specifications for Energy Storage Container Foundation Pit

What is pit thermal energy storage (PTEs)?

Pit thermal energy storage (PTES) is one of the most promising and affordable thermal storage, which is considered essential for large-scale applications of renewable energies. However, as PTES volume increases to satisfy the seasonal storage objectives, PTES design and application are challenged.

What are the requirements for foundation pit support?

As a structural system, foundation pit support should meet the requirements of stability and deformation: the two limit states mentioned in the general specification, i.e. the bearing capacity limit state and the normal use limit state[1-2].

What is the size of a foundation pit?

The size of the foundation pit is a square with a length of 30m on one side. The length, width and height of foundation soil are 100m, 100m and 30m respectively. The depth of the underground continuous wall is 15m and the thickness is 1m. Support forms are divided into ring beam support and straight beam support.

How big is the proposed excavation pit?

Project Overview The proposed excavation pit is an irregular rectangle that is approximately 130 m long and 89.8 m wide, with a perimeter of about 412 m and an excavation depth of 22.7 m.

How deep are foundation pits in China?

The excavation depth of many foundation pits in China is more than 30 m, such as the Shanghai World Expo Substation 34 m Foundation Pit , the Shanghai Dongjiadu restoration project pit of up to 41 m , etc.

Do you have the Right Foundation for your energy storage project?

When it comes to energy storage projects, having the right foundation involves careful planning upfront. But each site is different, requiring careful consideration for details like the types of equipment being supported, site location and geologic factors.
