Steel jacket box bearing platform cofferdam process
The invention discloses a cofferdam process for a steel jacket box bearing platform. Comprising the following steps of prefabrication, pile foundation construction, bottom beam construction, bottom plate hoisting, steel jacket box side wall assembly, internal reinforcing structure installation, bearing beam construction, hydraulic jack construction, counter-force beam construction, overall steel jacket box lowering and first-layer bottom sealing concrete pouring. And a second layer of bottom sealing concrete is poured. A steel bottom plate in the prior art is replaced by the concrete bottom plate, so that the using amount of steel is saved, and the construction cost is reduced. Each unit steel side wall of the side wall of the steel jacket box has enough rigidity, so that the unit steel side walls are not prone to toppling in the process of sequentially assembling the unit steel side walls end to end, more temporary auxiliary supporting structures such as inclined struts are allowed to be omitted, and the construction efficiency is greatly improved. A mechanical jack is replaced by the hydraulic jack, so that the balance degree and efficiency in the steel jacket box lowering process are improved.
本发明公开了钢套箱承台围堰工艺，包括如下步骤：预制步骤、建设桩基础步骤、搭建底梁步骤、吊装底板步骤、拼装钢套箱侧壁步骤、安装内部补强结构步骤、搭建承重梁步骤、搭建液压千斤顶步骤、搭建反力梁步骤、整体下放钢套箱步骤、浇筑第一层封底混凝土步骤、浇筑第二层封底混凝土步骤。通过混凝土底板代替现有技术中的钢底板，从而节约了钢材的用量以降低工程造价。钢套箱侧壁的每块单元钢侧壁本身具备足够的刚度，因而在依序首尾地拼装单元钢侧壁的过程中，单元钢侧壁不易倾倒，从而允许省略较多的斜撑等临时辅助支撑结构，从而大大提高了施工效率。通过液压千斤顶取代机械千斤顶，以提高钢套箱下放过程的平衡度和效率。
