皮带式吹砂船在深厚淤泥底质条件下施工技术

Construction technology of belt-type sand blower under the condition of deep silt

随着社会经济的发展,在城市近滩涂处进行填海造地施工的需求逐渐增多。近滩涂处常年受水力作用影响,多为淤泥淤积地带,同时紧邻城市生活区,对填海造地的施工工艺的选择要求较高。以马来西亚新山丽都林荫大道吹填造地项目为载体,以皮带式吹砂船为主要施工设备,研究类似工程的施工工艺,从采用高精度雷达来准确测定船舶装舱量、优化现场施工部署以减少流失量等措施入手,总结工程施工经验。

With the development of social economy,the demand for land reclamation construction near the tidal flats is increasing gradually.Affected by water power all the year round,the near-tidal flat is mostly silted and adjacent to urban living areas,which requires higher selection of construction technology for reclamation.Based on the land reclamation project of Lido Boulevard in Xinshan,Malaysia,and with the belt-type sand blower as the main construction equipment,the construction technology of similar projects was studied.The engineering construction experience was summarized starts with the measures such as using high-precision radar to accurately measure the vessel loading capacity and optimizing the site construction deployment to reduce the loss volume.
