Example 1
Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 illustrates the logical principle of the method for laying a spaced-apart ground rail. Specifically, fig. 1 is a logic schematic diagram of a spaced-apart supported ground track laying method according to an embodiment of the present invention.
The method for laying the ground track supported at intervals comprises the steps S110 to S160.
S110, adjusting the adjusting nut 4 of the foundation bolt 5 to a set height; the anchor bolts 5 are pre-installed to the supporting steel plate 6 using the first fastening nuts 3.
Specifically, the adjusting nuts 4 of the anchor bolts 5 are adjusted to a uniform elevation, the bolt holes of the support steel plates 6 are inserted through the anchor bolts 5, and then the support steel plates 5 are roughly leveled by screwing one of the fastening nuts 3 above the support steel plates 6. The pre-mounting here is only to manually tighten the first fastening nut 3. That is, the anchor bolts are through bolts, and the impact force from the rail 1 is transmitted to the ground by the through bolts, thereby extending the life of the rail.
S120, measuring the track installation position of the paying-off mark above the supporting steel plate 6, and hoisting the steel rail 1 on the supporting steel plate 6 according to the track installation position.
Fig. 2 and 3 illustrate a scene structure of the spaced-apart ground track laying method as a whole. Specifically, fig. 2 is a schematic structural view of a spaced-apart support ground track laying method according to embodiment 1 of the present invention. Fig. 3 is a side view of fig. 2.
As shown in fig. 2 and 3, the rail mounting locations include a rail centerline and a rail edge line. That is, the center line and the edge line of the rail are popped out with ink lines above the respective supporting steel plates 6. Then the steel rail 1 is hoisted on each supporting steel plate 6, and rail pressing device bottom plates are welded on the supporting steel plates 6 at the two sides of the rail after the edges are aligned.
S130, welding the rail pressing device bottom plate 2 on the supporting steel plates on the two sides of the steel rail, and pre-installing the rail pressing device cover plate and the rail pressing device bottom plate through rail pressing device bolts.
The rail pressing device 2 comprises a rail pressing device bottom plate, a rail pressing device bolt and a rail pressing device cover plate; the rail pressing device cover plate and the steel rail are fixed on the rail pressing device bottom plate through the rail pressing device bolts. The rail pressing devices are symmetrically and uniformly arranged along two sides of the steel rail at a distance not more than 500-600 mm. The rail pressing device is characterized in that a T-shaped groove hole is formed in the rail pressing device bottom plate, the rail pressing device bolt penetrates through the T-shaped groove hole and enables a bolt head of the rail pressing device bolt to be sunk in the groove hole.
That is to say, set up relative through-hole on pressing the rail ware bottom plate and the rail ware apron, wear to establish rail ware bolt from pressing the rail ware bottom plate upwards, press the rail ware bolt to fasten in rail ware apron department. Since the ballast plate is welded to the rail base below it, the head of the ballast bolt must be sunk into the interior of the ballast base. In the specific implementation process, a stepped hole is formed in the rail pressing device base, and the size of an inner ring of the stepped hole is smaller than that of the head of a rail pressing device bolt. During installation, the screw rod of the rail pressing device bolt penetrates through the stepped hole, the head of the rail pressing device bolt is accommodated on the stepped platform, the bolt head of the rail pressing device bolt is sunk into the rail pressing device bottom plate, and the bolt head of the rail pressing device bolt is clamped and fixed.
In a word, after the rail pressing device bottom plate is firmly welded, the rail pressing device cover plate is pressed, the rail pressing device bolt of the rail pressing device cover plate is screwed down by hands, and a certain gap is formed between the steel rail and each supporting steel plate. It should be noted that, the rail pressing device cover plate and the rail pressing device bottom plate are pre-installed by manually tightening the bolts, so that a gap is reserved between the steel rail and the support steel plate.
In specific implementation process, an elastic base plate can be arranged between the steel rail and the supporting steel plate, imbalance caused by small gaps can be eliminated by arranging the elastic base plate, and the service life of the steel rail can be prolonged by increasing buffering.
S140, the first fastening nut 3 is removed, and the rail pressing device bolt is fastened until the steel rail 1 is tightly pressed with the support steel plate 6. That is, the fastening nut above the supporting steel plate 6 is loosened, and then the rail presser bolt is further tightened with a tool such as a wrench, to eliminate the gap between the rail and the supporting steel plate.
The rail pressing device bottom plate is welded firstly, then the supporting steel plate and the steel rail are assembled, and secondary grouting is carried out after the steel rail is installed and aligned. Namely, after the support steel plate 6 of the steel rail and the steel rail 1 are connected into a whole through the rail pressing device 2, the installation and the alignment are simple and convenient. The rail pressing devices on two sides of the steel rail do not need to be adjusted left and right, and secondary adjustment caused by slippage of the rail pressing devices which are not flat on the road surface can not be generated. The multiple adjustment processes of steel rail installation are saved, and the efficiency of track laying is improved.
S150, adjusting the adjusting nut 4 until the top surface of the steel rail 1 is on a horizontal plane with a set height.
Specifically, the adjusting nut 4 is adjusted until the top surface of the steel rail 1 is on the level of the set height, and the adjusting nut is adjusted until the top surface of the steel rail is on the level of the set height by arranging an electronic level gauge on the top surface of the steel rail, detecting the height of the top surface of the steel rail through a precision level gauge and adjusting the adjusting nut until the top surface of the steel rail is on the level of the set height.
And S160, completely fastening the foundation bolt by using the first fastening nut 3.
After the anchor bolt is completely tightened using the first fastening nut, a second fastening nut for reinforcement is installed above the first fastening nut. That is, after the top surface level of the steel rail reaches the design requirement by adjusting the adjusting nuts 4 below the supporting steel plates 6, the fastening nuts above the supporting steel plates 6 are tightened and the backup nuts are pressed to form double nut fixing. That is, the adjustment of the rail and the supporting steel plate is performed in two times of the pre-adjustment and the re-adjustment.
In conclusion, the invention relates to a ground track laying method of interval bearing, which eliminates the mounting error of a support steel plate by changing the mounting sequence, fastening a rail pressing device and the self rigidity of a track, and then performs secondary grouting, thereby achieving the technical effect of improving the mounting precision of the track.
However, it will be appreciated by those skilled in the art that various modifications may be made to the above-described spaced-apart support ground track laying method provided by the present invention without departing from the spirit and scope of the invention. Therefore, the scope of the present invention should be determined by the contents of the appended claims.
