Problems solved by technology

[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

Embodiment Construction

[0034] Such as Figure 1 to Figure 6 As shown, the steel trestle can be extended from the shore to and connected to the branch trestle 1 on both sides of the steel cofferdam 2 in the river, and the branch trestle and the steel cofferdam are located at the lower side water flow or wind direction of the steel trestle ( figure 1 The direction of current or wind is marked by an arrow).

[0035] The steel trestle bridge includes: a plurality of steel pipe piles 5 that are driven into the river bottom by a pillar driver and distributed at intervals as supporting piers; a fixed scissor support beam 6 is set between the upper parts of the horizontally adjacent steel pipe piles; And the lower transverse distribution beam 11 which connects the upper ends of a row of three steel pipe piles in a horizontal direction, and the Bailey beam 7 which is located at the upper end of the lower transverse distribution beam and is vertically connected in series with the lower transverse distribution...

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.
