Improving the construction quality of underwater concrete pouring pipes

At the current stage, the construction of domestic underwater concrete pouring pipe engineering is usually carried out by the pipe method. The principle is that under the action of a certain drop pressure, the concrete mixture passes through the entrance of a sealed steel pipe (or a hard non-metallic pipe with higher strength) and enters the concrete under the initial pouring, supporting the concrete and The mud or water on it rises to form a continuous dense concrete pile. The technical requirements of the duct method are very strict. In order to ensure the construction quality of underwater concrete cast-in-situ piles, it is necessary to control it from the aspects of construction equipment, concrete preparation, and pouring to improve the underwater construction quality.

Strict requirements for the quality of construction equipment

Construction equipment required for concrete pouring must be complete and intact. This is the basic premise for ensuring the quality of poured concrete. To emphasize the quality of the following construction equipment:

1) The number of backup generators is sufficient. It is necessary to ensure that the performance of the backup generator at the construction site is good enough to cope with the power outage situation that may occur during the construction process, which can prevent the delay of the filling time.
