- Abstract
The filling technology by spreader pontoon is widely used in the reclamation project. According the difference source power of filling, it can be divided into hydraulic filling and mechanical. This paper focuses on the application of hydraulic filling in reclamation work. The method of hydraulic filling is the most difficult part of offshore backfilling operation. and the filling quality is the top priority of construction control. In the actual construction, if there are problems such as silt squeezing and arch silting, it will have a great impact on the foundation treatment processes such as conventional drainage board and mixing pile. Relying on the main reclamation works of Hong Kong International Airport third runway system project, this paper sorts out the hydraulic filling technology mainly invested in the project, systematically introduces the construction principle and construction control points of each hydraulic filling technology, expounds it from the aspects of construction quality control, explores the measures and methods to improve the quality in combination with the actual project, so as to improve the application of hydraulic filling technology in reclamation projects.
