AI Technical Summary
In the prior art, when laying tracks, the connection between the rail and the paving is not stable enough, which easily generates body impact during the turning of the train, causing the rail to move. The paving materials are cumbersome, and a large amount of gravel or basins are required to increase the dilution.
The head-point triangular expansion bolt or the head-round expansion bolt are used to fix the connection between the rail and the paving to form a triangular structure, increasing the area and force of the paving and triangles to reduce the pressure on the ground.
It improves the stability of rails and paving, reduces labor and time for manual bolts, saves materials, increases the dilution of paving, and prevents sinking and excessive ground pressure.

Abstract
Description
[0001] In the background technology of the technical field, track bedding has been laid on the track ground. The two ends or both sides of the bedding are connected with steel rails above. The distance between each bedding and the outside of the bedding is 86 cm. Each bedding is made of cement fine sand. It is fixed with bolts of 22 mm to 28 mm. Each bedding requires 8 bolts. A large amount of crushed stones or ballast is laid under the inner and outer sides of the two steel rails. The bottom width of the steel rail under the two ends of the bedding bears very little area of the steel rail, and it requires a lot of labor and time.
[0002] The technical purpose of the present invention is to make the "triangular bedding for placing steel rails" more stable, preventing the steel rails from moving due to the impact force of the train during turning, increasing the density of the bedding, solving the previous density problem, and not laying crushed stones or ballast on the track ground. The increased width of the two beddings is 197 cm, which is the distance of the old technology.
[0003] 〔The effect of the present invention and the most effective implementation method: Use pointed-head triangular expansion bolts or round-head expansion bolts with a depth of 22 mm to 32 mm and 35 cm to 70 cm to drive nails to fix the connection between the steel rails and the bedding. It saves the materials, labor and time spent, reduces the force required for manual bolt fixation, uses cinder as the bedding material, is convenient for installation and transportation, increases the bearing area and strength of the bedding and the triangle, prevents the ground from sinking in the form of the bedding or the triangle, and can bear a large pressure. It is connected into a triangle shape of 30° to 170°.〕
[0004] 〔Instruction manual appendix Figure 1 For the technical solution of the manufacturing and implementation method of this product. In the form of self-creation and views, randomly select one end of the head surfaces of bedding 1 and bedding 2 to connect. Draw a center hole at 23 cm to 24.5 cm on the head surface. Drive nails with pointed-head triangular expansion or round-head pointed expansion bolts with a depth of 22 mm to 32 mm and 35 cm to 70 cm, and connect the holes. Bedding 3 is used to connect continuously in the order for the track. The distance between bedding 4 and bedding 5 is the existing technology. The 19th line segment is 50 cm to 58 cm, and 20, 21, 22, 23, 24, 25, 26, 27 are the bolt holes for connecting and fixing the steel rails in the existing technology bedding; the connecting holes for bedding 6 and 7; the 8th line segment, the full length of the bedding is 200 cm to 242 cm; the 9th line segment, the width of the bottom surface of the bedding is 23 cm to 25 cm, and the width of the upper surface is 17 cm; the 10th line segment, the width of the bedding is 23 cm to 25 cm; the 11th bedding line segment is 200 cm to 242 cm; the 12th and 13th line segments are the outer side lines of the steel rails; the 14th and 15th line segments are the inner side lines of the bottom of the steel rails; the 28th and 29th are the center lines of the steel rails; the 16th line segment, the distance between the inner side lines of the two steel rails is 136 cm; the 17th and 18th line segments are the center lines of the steel rails; the 30th line segment, the outer side line of the upper steel rail 2 is 157.5 cm.
[0005] Randomly select one end of bedding 1 and bedding 2 to connect to form a triangular bedding. The distance between the connections of the two bedding ends is 283 cm, which is 2.3 times the increased width of 197 cm of the two existing beddings in the old technology.〕
