Assembly type cable tunnel anti-seismic structure
The invention belongs to the technical field of assembly type cable pre-embedded structures, and particularly relates to an assembly type cable tunnel anti-seismic structure. The concrete prefabricated top plate and the concrete prefabricated U-shaped component are connected through the stainless steel cylindrical bolt pins, the integrity of upper and lower components of the structure is improved, and the transverse anti-seismic performance of the structure is guaranteed; the prefabricated through holes and the bolt pin holes are sealed by adopting C30 micro-expansion fine aggregate concrete, so that the waterproof and anti-corrosion properties are ensured; the grouting sleeves are adopted for the inner longitudinal steel bars, staggered arrangement is formed, rabbets are achieved, construction operation is convenient, the requirement of a sealing structure is met, and continuity of resistance and rigidity needed by longitudinal seismic resistance of the structure is guaranteed; compared with a traditional cable tunnel, assembly type prefabrication can accelerate the construction progress, improve the component manufacturing precision and construction quality, reinforce the anti-seismic structure of the structure and guarantee the anti-seismic performance of the structure.
本发明属于装配式电缆预埋结构技术领域，具体涉及为一种装配式电缆隧道抗震结构；本发明采用不锈钢圆柱销栓连接混凝土预制顶板与混凝土预制U形构件，增加结构上下构件的整体性，保证结构横向抗震性能；预制通孔和销栓孔采用C30微膨胀细石混凝土密封，保证其防水、防腐蚀性能；本发明内部纵向钢筋均采用灌浆套筒，并且形成错位排列，实现企口，方便施工操作，达到密封结构的要求，保证结构纵向抗震所需的抗力和刚度的连续；本发明与传统电缆隧道相比，装配式预制可以加快施工进度，提高构件制造精度和施工质量，加强结构的抗震构造，保证其抗震性能。
