Large-pipe-diameter river-crossing immersed tube underwater foundation trench leveling construction method
The invention discloses a large-pipe-diameter river-crossing immersed tube underwater foundation trench leveling construction method, and belongs to the field of civil engineering construction. The large-pipe-diameter river-crossing immersed tube underwater foundation trench leveling construction method comprises the following steps that firstly, construction measurement is conducted, specifically, the plane position of a pipeline is measured by a measurer, and the foundation elevation of the measured position is calculated; then a buttress is installed, a guide rail is placed on the buttress, a scraper is placed on the guide rail, and sand and pebbles are thrown and filled according to the foundation elevation; when the elevation for throwing and filling the sand and the pebbles is close to the designed elevation, a diver performs underwater leveling until the designed elevation is met; and finally, after the foundation is leveled, self-inspection is carried out, and after self-inspection is qualified, foundation trench foundation leveling acceptance inspection is carried out. Compared with the prior art, the process of the construction method is more perfect, and the project quality can be better guaranteed through self-inspection and foundation trench foundation leveling acceptance inspection.
本发明公开一种大管径跨江沉管水下基槽平整施工方法，属于土木工程施工领域。大管径跨江沉管水下基槽平整施工方法包括如下步骤：首先施工测量，测量人员测定管道的平面位置，推算测量位置的基础标高；然后安装支墩，在所述支墩上安放导轨，在所述导轨上放置刮刀，根据所述基础标高抛填砂卵石；当抛填砂卵石的标高接近设计标高时，潜水员水下整平，直到符合设计标高；最后，基础整平后，进行自检，自检合格后进行基槽基础整平验收。施工方法流程相较于现有技术更加完善，通过自检和基槽基础整平验收更能保证工程质量。
