Abstract:In bridge construction, the anti-corrosion properties and strength of the cable body are constantly improved. The epoxy coated steel strand is widely used because it meets the above requirements, and the application of epoxy coated steel strand in the cable system is more advantageous. Yibin Zhongba Bridge adopts front fulcrum hanging basket and steel strand stay cable. This paper introduces the construction process and describes the application of epoxy coated steel strand stay cable in the cable-stayed bridge.

Abstract:3) The bridge floor is towed with 5 tons of slow winch as power,6/8 "steel wire rope and outlet (2 six-door hoists to wear the steel wire rope) as traction, 7.5cm seamless steel pipe as pipe, and slowly move to the required position on the road (16×22×250cm). 2, lifting beam in place 1)2 pieces of 40 meters long (?) The structural type and assembly of the load-bearing beam of the A-chord universal member are shown in Figure 7.

Abstract:This paper introduces the characteristics of self-anchored suspension Bridges, the development history of self-anchored suspension Bridges abroad and the situation of self-anchored suspension Bridges that have been built. The design and construction experience of self-anchored suspension bridge in China are introduced, and the development and application prospect of this bridge type are analyzed.

Abstract:This paper introduces the application of soil anchor cable in Huaian three-line ship lock, Jiangsu Province, and focuses on the application of OVM pressure distributed anchor cable in this soft, complex and high groundwater level stratum, which can better solve the problems of low soil bearing capacity and anti-corrosion of underwater anchor cable.

Abstract:The anti-corrosion performance of prestressed tendons plays a crucial role in the durability of hydraulic and bridge structures. This paper introduces a new kind of prestressed tendon-epoxy sprayed steel strand with good anti-corrosion properties developed by Liuzhou OVM Company, and its application in hydraulic engineering and bridge engineering.

Abstract:In this paper, a kind of pipe bending machine for prestressed engineering is proposed, and the feasibility of using friction mechanics principle and self-adaptive plastic deformation of steel pipe to process curved pipe is demonstrated.
