广州珠江电厂煤码头改造技术创新

Technical innovation for transformation and upgrading of coal wharf

分析项目历史资料,为满足系统升级改造及不影响电厂正常运行的要求,进行多方案比选。根据旧码头升级改造场地受限、新旧结构衔接等特点,带式输送机大胆采用非标准带速,在适应基础条件的情况下,达到减少能耗、降低成本、平稳安全的目的;码头加长段采用大直径斜嵌岩管桩梁板结构,加固段创新采用斜嵌岩管桩后支撑墩结构,达到减少沉降、减少对原码头结构和码头正常使用的影响的目的。该加固改造技术可为类似项目的实施提供借鉴。

Based on different transforming and the analysis of the historical upgrading schemes, to satis and ensure normal operation of the power plant. In view data of a coal wharf＇s construction, we develop and compare fy the requirement of the systematic upgrading of facilities of the limited space for upgrading and necessity of matching joints between the new structures and the old ones, a non-standard design speed of conveyance belt is adopted which result in saving cost, reducing power consumption and stabilizing the operation in a safe manner if fitted with the basic conditions; And a deck structure supported on rake large-diameter socketed-in-rock tubular piles is adopted for the extended section of wharf, while a kind of creative structure with strut piers supported on rake socketed-in- rock tubular piles is used for the reinforced section, so as to reduce the settlement and minimize the influence on the original structures and operation on the wharf. This method of wharf upgrading may serve as referencefor other projects of the same nature in the future.
