Basement construction requires high experience and expertise from contractors and construction units. Lack of correct engineering can lead to serious problems when the project is put into use. In this article, Le Thy Construction will introduce effective and time-saving basement construction methods. Please refer now!
1. Basement Construction Method: Excavation First, Construction From Bottom Up
This is a traditional method, usually applied to holes that are not too deep.
According to this method, the construction unit will dig the hole to the depth of the foundation, then proceed with construction from bottom to top. However, this method can cause instability of the excavation wall.
Advantage:
- Simple construction
- High precision
- Architectural and structural solutions are not too complicated
- Easy waterproofing and technical network installation
Defect:
- Can easily cause danger to neighboring structures, especially in crowded construction areas
- Construction time is longer than other methods
2. Open Tunnel Construction Method
The open tunnel method is one of the most effective construction methods, not requiring retaining walls or rows to hold the excavation wall. The applicable conditions are that the basement wall must be able to withstand the pressure load of the soil and use barrette pile technology.
Advantage:
- Simple construction
- Materials used can be recovered after construction
Defect:
- Takes up a lot of space in the excavation pit, affecting construction
3. Top-Down Method
The top-down method is used when construction time is prolonged. The construction unit will work from the top down, and at the same time build the house body from the bottom up, taking the ground as the starting point.
Construction steps:
- Construction of walls in soil and pre-drilled piles
- Pour concrete on the ground floor right on the natural ground, the ground floor is placed on the ground wall and basement column.
Advantage:
- Construction progress is quick due to the parallel construction of the body and underground parts
- Solve the problem of waterproofing soil walls
- There is no need for a system of scaffolding or formwork for the floor beam structure
Defect:
- Many cracks may appear on the floor beam structure due to the large opening size
- Risk of breaching the diaphragm wall causing collapse
- Faced with flooding during construction
Above are the current popular basement construction methods compiled by Hoa Binh Construction. Hopefully this article will help you choose the right construction solution for your project.
