Hoop type prefabricated open caisson pipe ring structure and construction method thereof
The invention relates to a hoop type prefabricated open caisson pipe ring structure and a construction method thereof. The hoop type prefabricated open caisson pipe ring structure comprises a plurality of prefabricated pipe pieces which are spliced and connected to form a pipe ring; the tensioning table is arranged on the outer arc surface of one segment in each ring; one end of the prestressed tendon is anchored on the tensioning table, the prestressed tendon is wound on the pipe ring, the other end of the prestressed tendon penetrates through the tensioning table and is anchored on the tensioning table after being tensioned, and the pipe ring is hooped and fixed through the prestressed tendon. The prefabricated pipe piece is formed by splicing a plurality of prefabricated pipe pieces, and the prestressed tendons are adopted for tensioning and anchoring, so that the plurality of pipe pieces in each ring form an integral stress system under the circumferential acting force of the prestressed tendons; the defects that in the open caisson cast-in-place technology, due to the fact that reinforcing steel bar binding, formwork support erecting and concrete pouring need to be carried out on a construction site, the construction period is long, the occupied area is large, and the surrounding environment is greatly influenced are overcome, and the problem that an existing prefabricated open caisson pipe ring structure is poor in overall stability and prone to water and soil leakage is solved.
本发明涉及一种套箍式预制沉井管环结构及其施工方法，包括：预制的若干片管片，若干片管片拼接连接形成管环；设于每环中一管片的外弧面上的张拉台；一端锚固于张拉台上的预应力筋，预应力筋绕设于管环上，预应力筋的另一端穿设于张拉台上且经张拉后锚固于张拉台上，通过预应力筋将管环箍紧固定。本发明由预制的若干片管片拼装而成，采用预应力筋张拉锚固，使每环的若干片管片在预应力筋环向作用力下形成整体受力体系，克服了沉井现浇工艺因需在施工现场绑扎钢筋、架设模板支架、浇筑混凝土而导致的施工周期长、占地面积广、周边环境影响大的缺点，解决了现有预制装配式沉井管环结构整体稳定性较差而容易产生水土渗漏的问题。
