防波堤胸墙施工中门架模板一体式的工艺

Integrated construction technology of gantry mounting and template for breakwater crest wall

为了高质高效地完成某深水防波堤1 510 m防浪胸墙施工,根据防浪胸墙高6.5 m、掺石20%、通道狭窄等难点,在对防浪胸墙施工工艺进行了深入的研究后,创新地采用了门架模板一体式施工工艺。针对该工艺,综合考虑模板安拆、抛石工艺、资源配置等情况,设计了底层胸墙门架、顶层胸墙门架。该特殊施工工艺在保证防浪胸墙浇筑质量的前提下,创造了防波堤施工史上的最快速度。

In order to guarantee the quality and efficiency of a deepwater breakwater＇s 1 510 m long crest wall, according to the difficulties that the wave breast wall is of 6.5 meters high, containing 20% stones, and with narrow passages, etc. we carry out a research on the construction technology of the crest wall, and develop the integrated construction technology of gantry mounting and template innovatively. For the technology, we design the bottom crest wall gantry mounting and the top crest wall gantry mounting in view of the temptate＇s installation, riprap technology, as well as the allocation of resources. By the special technology, we realize the quickest construction at that time under the prerequisite of guaranteeing the casting technology of the crest wall.
