Adsorption type shield bottom dry chamber cabin operation method suitable for underwater concrete damage repair
The invention belongs to the technical field of hydraulic engineering hub safety danger removal and reinforcement, and discloses an adsorption type shield bottom dry chamber cabin operation method suitable for underwater concrete damage repair, and the adsorption type shield bottom dry chamber cabin is carried into water by a submersible and sails to the underwater concrete damage position; after the shell covers the damaged part, rubber preliminary water stopping is conducted firstly, then the shell is adsorbed to the underwater concrete surface, and then internal water pumping and air inflation are conducted, so that a local dry environment relative to the outside is formed in the shell and used for overhauling underwater concrete. On one hand, good adsorption on an underwater concrete surface is completed, so that fitting is tighter, the water stopping effect is better, and meanwhile the overall stability is improved; on the other hand, the internal water body is reduced through water pumping, the internal water body can be discharged through air inflation, and meanwhile it is guaranteed that the external water body cannot enter the shell, so that a dry operation environment is better achieved; therefore, the problem of water stop sealing under the condition of large water depth is solved, and maintenance under the condition of large water depth is guaranteed.
本发明属于水利工程枢纽安全除险加固技术领域，公开了一种适用于水下混凝土破损修复的吸附式盾底干室舱作业方法，采用吸附式盾底干室舱由潜水器携带入水并航行至水下混凝土破损处；壳体将破损处笼罩后，先进行橡胶初步止水，再与水下混凝土面进行吸附，之后进行内部抽水、充气，使壳体内部形成一个相对于外界的局部干燥环境，用于对水下混凝土进行检修。一方面，完成在水下混凝土面的良好吸附，使得贴合更紧密，止水效果更好，同时增加了整体稳固性；另一方面，通过抽水使内部水体减少，充气也可使内部水体外排，同时保障外界水体无法进入壳体内部，进而更好的实现干燥作业环境；因而突破了大水深条件下的止水密封难题，保障了大水深情况下检修。
