1. Acceptance of finished piles After the PHC piles are transported to the site, the relevant quality assurance information of the piles provided with the

Nowadays, the construction of large buildings is becoming more and more common. The increase in the scale of buildings has higher and higher requirements for

Today, we will compare rotary drilling rigs with commonly used impact and rotary drilling rigs in the past, and give some suggestions on how to

For rotary bored piles, controlling the thickness of sediment at the bottom of the pile is the key to quality control of pile foundation construction.

With the continuous development of engineering technology, new steel piles and reinforced concrete piles are becoming more and more widely used in engineering construction. Different

Venue Layout The construction site mainly includes three parts: the underground diaphragm wall forming area; the mud system area; and the steel cage processing area.

Foundation engineering is an extremely important part of construction projects, whether it is the treatment of problems such as “miscellaneous filling”, “weakness”, “collapse”, “liquefaction” and

The cushion method is to dig out the weak soil layer within a certain range under the base of the foundation, then fill it in

1. What should I do if the drilling hole is offset? 1. Quality problems and phenomena 1) The hole is not vertical after being formed,

1. Slope excavation (Large excavation) method There are no supports or supporting structures in the pit; it is convenient for the construction of large-scale excavating
