Device for sinking micro open caisson
The invention provides a device for sinking a micro open caisson, which is characterized in that the open caisson is arranged in an open caisson bracket (11) on an annular base (10), and the sinking construction is started. When the open caisson blade foot section (5) encounters stones or hard soil layers, the open caisson is difficult to sink, and the designed sinking speed cannot be reached, the open caisson blade foot section is driven to be opened and closed by controlling a piston of the jack (7), soil and stones below the blade foot section are squeezed towards the two sides of the open caisson wall, the sinking resistance after the blade foot section is closed is reduced, and the open caisson is made to sink smoothly.
本发明提供一种用于微型沉井下沉的装置，沉井安装在环状底座上(10)的沉井托槽(11)内，开始下沉施工。当沉井刃脚瓣(5)下遇到石块或硬土层，沉井下沉困难，无法达到设计下沉速度时，通过对千斤顶(7)的活塞的控制，带动沉井刃脚瓣的开合，将刃脚瓣下的土石向沉井壁两侧排挤，减小刃脚瓣合拢后下沉的阻力，使沉井顺利下沉。
