Example Embodiment

[0018] Such as figure 1 figure 2 As shown, the construction method for strengthening the H-shaped steel line includes the following steps:

[0019] 1. Build four groups of deep foundation piles 2 on both sides of the existing railway line 1, two groups on each side, each group includes multiple deep foundation piles arranged in the same direction as the railway;

[0020] 2. Cross the beam I-beam 3 between each sleeper gap under the railway line 1, so that the beam I-beam 3 vertically crosses the railway line 1 and straddles the deep foundation piles 2 on both sides of the railway. Cross beams Before the I-beam 3, the ballast between the sleepers must be dug to pass through the I-beam 3; and the spacing between the existing sleepers must be adjusted; after all the I-beam 3 is installed, the Fill the gap between the crossbeam I-beam 3 on the four-corner deep foundation pile 2 and the deep foundation pile 2 with wood planks and wooden wedges;

[0021] 3. On the two sets of deep found...

Abstract

The invention belongs to a construction method for railway line engineering, and in particular relates to a line reinforcing construction method for reinforcing the traditional railway line when a frame bridge is built. The line reinforcing construction method comprises the following steps of: 1. building four groups of deep foundation piles at the two sides of the traditional railway line, wherein each two groups of deep foundation piles are arranged at one side, and each group comprises multiple deep foundation piles which are arranged in the same direction as the railway; 2. penetrating crossbeam I-shaped steel through each railway sleeper gap under the railway line so that the crossbeam I-shaped steel vertically passes through the railway line and stretches across the deep foundation piles at the two sides of the railway; 3. laying two H-shaped steel on the crossbeam I-shaped steel above the two groups of deep foundation files at the same side of the railway line; 4. arranging square timbers between railway tracks and the H-shaped steel; and 5. dismantling line reinforcing systems and recovering the lines after a bridge is propped in place. The H-shaped steel is 900 H-shaped steel 4; and the crossbeam I-shaped steel is I45b I-shaped steel. The line reinforcing construction method can ensure the safety driving of the traditional railway line to the maximum limit under various complicated geological conditions.

Description

technical field [0001] The invention belongs to a railway line engineering construction method, in particular to a line reinforcement construction method for reinforcing existing railway lines when building a frame bridge. Background technique [0002] With the rapid progress of urbanization, many new road facilities came into being. Some newly-built road facilities must pass under the existing railway lines. When passing through the railway lines, a frame bridge must be built so that the railway lines are located on the top of the frame bridge, and the road is located under the frame bridge and is perpendicular to or perpendicular to the railway lines. Diagonal. When building a frame bridge, pre-reinforcing the railway line on the top of the bridge to keep it stable from the influence of external construction is an essential key process for building a frame bridge. At present, there are mainly two methods for reinforcing railway lines, one is the method of vertical liftin...
