Fabricated composite open caisson structure for pipe jacking construction
The invention discloses a fabricated composite open caisson structure for pipe jacking construction. A reserved hole is formed in the side wall of an open caisson, and the open caisson structure comprises a cast-in-place part and a prefabricated pipe piece splicing part; the top end of the cast-in-place part is 1 meter higher than the reserved hole, the inner wall face of the cast-in-place part is aligned with the inner wall face of the prefabricated pipe piece splicing part in an up-down mode, and a step is defined between the top end of the cast-in-place part and the outer wall face of the prefabricated pipe piece splicing part; a waterproof mortar layer and a water stop rubber plate layer are arranged between the top end of the cast-in-place part and the bottom end of the prefabricated pipe piece splicing part and serve as a waterproof connecting layer; an inner steel plate is arranged at the inner end of the waterproof connecting layer, the upper portion of the inner steel plate is connected with the bottom of the prefabricated pipe piece splicing part through chemical bolts, and the lower portion of the inner steel plate is connected with the top of the cast-in-place part through chemical bolts. The invention further discloses a corresponding construction method. The structure of the cast-in-place part and the structure of the prefabricated pipe piece splicing part are overall designed, the advantages of the cast-in-place technology and the advantages of the prefabrication technology are integrated, the defects of the cast-in-place technology and the defects of the prefabrication technology are overcome, and compared with the cast-in-place technology and the prefabrication technology, the construction efficiency is improved, the structural stability is good, and the environment-friendly treatment pressure is small.
本发明公开了一种顶管施工用装配式复合沉井结构，沉井侧壁具有预留洞口，包括现浇部分与预制管片拼装部分；现浇部分的顶端高于所述预留洞口1米，现浇部分的内壁面与预制管片拼装部分的内壁面上下对齐，现浇部分的顶端与预制管片拼装部分的外壁面之间围成台阶；现浇部分的顶端与预制管片拼装部分的底端之间设有防水砂浆层和止水橡胶板层并作为防水连接层；防水连接层的内端处设有内钢板，内钢板的上部通过化学螺栓与预制管片拼装部分的底部相连接，内钢板的下部通过化学螺栓与现浇部分的顶部相连接。本发明还公开了相应的施工方法。本发明统筹设计现浇部分和预制管片拼装部分的结构，综合了现浇和预制两种工艺的优点，避免了各自的缺陷，相比现浇和预制两种工艺均提高了施工效率，结构稳定性好，环保处理的压力较小。
