titleOfInvention | Cofferdam hoisting and lowering construction device and cofferdam hoisting and lowering construction method |
abstract | The invention relates to a cofferdam hoisting and lowering construction device and a cofferdam hoisting and lowering construction method, wherein the cofferdam hoisting and lowering construction device comprises: the steel protects a section of thick bamboo, gallows, jack and lifting rope, still includes a plurality of twisted steel jibs, and the lower extreme is used for being connected with cofferdam hoist and mount to and go up support nut, the spiral assembly is in on the twisted steel jib for take corresponding twisted steel jib to support on corresponding fixed basis when setting for the position down at the cofferdam, form redundant protection. During the use, lifting rope and dry twisted steel jib all are connected with the cofferdam hoist and mount, and when unexpected fracture appeared at the lifting rope, the cofferdam will take the twisted steel jib whereabouts, support the cooperation with corresponding fixed basis through last support nut up to, hang the cofferdam by fixed basis through last support nut, twisted steel jib, avoid the cofferdam to last the tenesmus. Configuration lifting rope and twisted steel jib utilize the twisted steel jib to form redundant protection, improve the security that construction equipment was transferred in the hoist and mount of whole cofferdam. |
