Method and a reinforcing device for transverse limit and reinforcement of the middle part of a steel trestle

Abstract

The invention relates to a method and a reinforcing device for transverse limit and reinforcement of the middle part of a steel trestle, the limiting and reinforcing device comprises a first reinforcing steel pipe pile, the second reinforced steel pipe pile and the third reinforced steel pipe pile, slide block, The first reinforced steel pipe pile, the second reinforced steel pipe pile and the third reinforced steel pipe pile are triangular in distribution, and the third reinforced steel pipe pile is provided with two sliding paths at intervals on the outer surface of the third reinforced steel pipe pile. The sliding block is located between the two sliding paths, and the inclined support beam obliquely supports the upper part of the outer side of the third reinforced steel pipe pile. Thesteel trestle has the advantages of simple structure, low cost, strong applicability, stable and reliable performance, strong maneuverability and good use effect, and has the advantages of improving the overall rigidity of the steel trestle, enhancing the resistance to water flow and wind load.

Description

technical field [0001] The invention belongs to a method and a reinforcement device for laterally limiting and reinforcing the middle part of a steel trestle bridge. Background technique [0002] Steel trestles are necessary temporary bridges for the construction of long-span bridges and land bridges distributed at intervals in water. The steel trestles of traditional crafts can meet the construction needs to a certain extent, but the overall stability and stiffness are poor. When the water level rises, the water flow accelerates, or the wind level increases, the force on the steel trestle bridge is like a simply supported beam with a uniform load in the middle, causing the steel trestle bridge to experience lateral displacement. In severe cases, the steel trestle bridge may even break or be washed away. Accidents will endanger the safety of personnel and machinery construction, and form potential safety hazards. At the same time, they will also cause property losses. The re...

[0002] Steel trestles are necessary temporary bridges for the construction of long-span bridges and land bridges distributed at intervals in water. The steel trestles of traditional crafts can meet the construction needs to a certain extent, but the overall stability and stiffness are poor. When the water level rises, the water flow accelerates, or the wind level increases, the force on the steel trestle bridge is like a simply supported beam with a uniform load in the middle, causing the steel trestle bridge to experience lateral displacement. In severe cases, the steel trestle bridge may even break or be washed away. Accidents will endanger the safety of personnel and machinery construction, and form a safety hazard. At the same time, it will cause property losses. The repair and reinforcement of the steel trestle bridge will prolong the construction period
