UHPC-based prefabricated cable trench turning connection method and construction process
The invention discloses a UHPC-based prefabricated cable trench turning connection method and a construction process, belongs to the technical field of power construction, and is suitable for turning connection of prefabricated cable trenches of various sizes, and the connection operation at the turning position of the prefabricated cable trench is carried out through a UHPC pouring and maintenance integrated connection device. The cast-in-place UHPC connecting method is adopted, the bonding performance is high, reinforcing steel bars do not need to be adopted for reinforcement, and the problem that in a cast-in-place common concrete connecting method, the reinforcing steel bars are difficult to arrange due to the fact that the turning position of the prefabricated cable trench is narrow is solved; durability is good, and the problem that mechanical connection of steel plates, bolts and the like is poor in corrosion resistance is solved; automatic maintenance operation after UHPC pouring can be achieved, the high humidity and temperature requirements during UHPC maintenance are met, the problem that power utilization on a construction site is difficult is solved, the UHPC quality stability is guaranteed, and it is ensured that prefabricated cable trench turning connection is reliable. And through an adjustable mechanical structure, different-angle turning connection requirements of prefabricated cable trenches of multiple sizes can be met.
本发明公开了一种基于UHPC的预制电缆沟转弯连接方法及施工工艺，属于电力施工技术领域，通过UHPC浇筑及养护一体化连接装置进行预制电缆沟转弯处的连接作业，适用于各种尺寸预制电缆沟的转弯连接。本发明采用现浇UHPC连接方法，黏结性能高，无需采用钢筋增强，解决了现浇普通混凝土连接方法中因预制电缆沟转弯处狭小而钢筋难以布置的难题；耐久性能好，避免了钢板、螺栓等机械连接耐腐蚀性能差的问题；可实现UHPC浇筑后的自动养护作业，满足UHPC养护时较高的湿度与温度要求，解决了施工现场用电困难的问题，并保证UHPC质量稳定，确保预制电缆沟转弯连接可靠。通过可调节机械结构，能够满足多尺寸预制电缆沟的不同角度转弯连接需求。
