Internal accurate adjustment device and system for alignment of submarine immersed tubes
The invention relates to the technical field of immersed tube tunnel construction, in particular to an internal accurate adjustment device and system for alignment of submarine immersed tubes. The internal accurate adjustment device a first immersed tube and a second immersed tube to form a combination cavity; a vertical push jack assembly and a horizontal push jack assembly are arranged; the inner side wall of each immersed tube is provided with vertical jack limiting assemblies; the vertical push jack assembly consists of a plurality of integrated jacks vertically installed; and the horizontal push jack assembly consists of a plurality of integrated jacks horizontally installed, and is placed on a track in the combination cavity. The integrated jacks employ a quick splicing method, and double closed-loop control on positions and force is employed, so that the accuracy of correction positioning is improved; and the internal accurate adjustment device for alignment of the submarine immersed tubes solves the problem that required thrust is large, a reaction point is hard to find, space is narrow, installation is inconvenient and the like by employing an existing alignment and deviation adjustment method for the submarine immersed tubes, and also solves the technical problems that the construction difficulty is high, the construction efficiency is low, the accuracy of correctionand positioning is low and the like.
本发明涉及沉管隧道施工技术领域，尤其涉及一种海底沉管对位的内部精调装置及系统，包括第一沉管和第二沉管形成结合腔，设有垂直推动千斤顶总成和水平推动千斤顶总成，沉管内侧壁上设有垂直千斤顶限位组件，所述垂直推动千斤顶总成由多个垂直安装的一体式千斤顶组成，所述水平推动千斤顶总成由多个水平安装的一体式千斤顶组成，放置于结合腔内的轨道上，一体式千斤顶采用快速拼接的方式，且采用位置和力的双闭环控制，提高纠偏定位精度，该海底沉管对位的内部精调装置解决了现有的海底沉管对位偏差调整方法存在的所需推力较大、反力点难找、空间狭小、安装不方便等难题，还解决了施工难度大、施工效率低下、纠偏定位精度低等技术难题。
