【摘要】：随着曹妃甸工业区开发建设的快速发展,对陆域面积的需求越来越大,围海造地工程就不断展开,工程施工中遇到的新问题也越来越多。以曹妃甸地区的某一围海造地工程为例,依据曹妃甸开发区的工程实地条件和施工作业环境以及对应的施工方案,有针对性的研究了曹妃甸开发区沿海地区围海造地和吹填设计施工的一系列重要步骤,包括不同地质条件、自然条件下如何采用不同的施工方案,具体到围堤各个施工步骤,围堤合拢关键点等。通过合拢失败的简要分析,突出了过程控制的重要性。结合后期吹填砂淤泥含量增大后采用竹-木排架架设吹填管线的成功经验,提供了吹填岸管铺设的新方法。简要介绍了吹填方案的选择对吹填效果的影响。通过相关论述,阐明了只有详细研究施工区域自然地理条件才能制定可行、高效的总体施工方案。总体施工方案确定后的关键点难点,如围堤龙口合拢、船型选择、淤泥条件下吹填管线接长方案、吹填方案选择等直接影响了工程进度快慢和工程经济效益。
[Abstract]:With the rapid development and construction of Caofeidian Industrial Zone, the demand for land area is increasing, and the land reclamation project has been carried out continuously, and the new problems encountered in the construction of the project are more and more. Taking a reclamation project in Caofeidian area as an example, according to the actual engineering conditions, construction environment and corresponding construction plan of Caofeidian Development Zone, A series of important steps in the design and construction of reclamation and reclamation in the coastal areas of Caofeidian Development Zone are studied, including different geological conditions, how to adopt different construction schemes under natural conditions, and concrete construction steps of the embankment. Embankment closure of the key points, etc. The importance of process control is highlighted through brief analysis of closure failure. Combined with the successful experience of using bamboo-wood bent frame to set up the pipe after the increase of silt content in the later stage, a new method for laying the pipe is provided. This paper briefly introduces the influence of the selection of the blowing scheme on the effect of the blow filling. This paper expounds that only by studying the physical and geographical conditions of the construction area in detail can a feasible and efficient overall construction scheme be formulated. The key points and difficulties after the determination of the overall construction plan, such as closure of the embankment, selection of the ship type, connection of the pipeline under silt conditions, selection of the filling scheme, etc., have a direct impact on the speed of the project and the economic benefits of the project.
