Abstract

The invention relates to a device and method for a prestressed duct, in particular to an antirust oil injection device for a steel cable in a prestressed duct and an oil injection method thereof, and belongs to the technical field of building engineering construction. The device and the method are designed for complex environments with large tonnage, super-long cables and anomalous events and are achieved through machining and manufacturing, simulation test and entity application practice. The device is simple in principle and convenient to operate; the profile occupied space is small, the weight is low, carrying is easy, the manufacturing cost is low, and the safety risk of high-altitude operation is low; the oil injection effect is good, cost is saved, efficiency is high, cost is low, and practicability is high; and at the same time, design requirements are met, the cost can also be lowered, the efficiency is improved, the time limit for a project is shortened, and the project quality is improved.

Description

technical field [0001] The invention relates to a device and method for a prestressed tunnel, in particular to a steel beam anti-rust fuel injection device in a prestressed tunnel and a fuel spray method thereof, which belong to the technical field of construction engineering. Background technique [0002] At present, in the prestressing construction, the anti-rust treatment of the steel strands is oil protection before penetrating into the tunnel, and the anti-rust protection technology and equipment for the steel strands in the tunnel are blank at home and abroad. However, in large-scale construction projects, roads and bridges, nuclear power plants and other projects, there are more and more applications of large-tonnage and ultra-long-beam prestressing, and the design requirements are also stricter. It is inevitable that abnormal events will cause shutdowns during construction. The shutdown will cause the prestressed beams that have been stretched and cut to be unable to...
