Description

Technical Field

[0002] A cast-in-place pile is a pile made by drilling in place and pouring concrete or reinforced concrete. Among many building pile foundations, cast-in-place piles have been widely used in the field of construction engineering due to their strong bearing capacity, no vibration during construction, low noise, and suitability for use in densely populated urban buildings. During the construction process, the pile top elevation is generally located at the bottom of the foundation pit. The pouring of concrete is determined by the on-site construction personnel based on their experience to determine whether the concrete has reached the pile top elevation. In order to ensure the quality of the concrete on the pile top, over-pouring is generally carried out, and the over-pouring height is generally 0.5-1.0m.
