Example 1
Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 depicts in general terms the logic principle of a spaced-support ground track laying method. Specifically, FIG. 1 is a schematic logical view of a method of laying spaced-apart supported ground tracks according to an embodiment of the present invention.
The method for paving the ground rails supported at intervals comprises the steps S110-S160.
S110, adjusting the adjusting nuts 4 of the foundation bolts 5 to a set height; the anchor bolts 5 are pre-mounted to the support 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, and then the bolt holes of the support steel plates 6 are threaded through the anchor bolts 5, and then the fastening nuts 3 above the support steel plates 6 are screwed first to approximately level the support steel plates 6. The pre-installation here is the manual tightening of the first fastening nut 3. That is, the anchor bolts are through bolts, and by providing the through bolts, the impact force from the rail 1 is transmitted to the ground, so that the life of the rail is prolonged.
And S120, measuring the track installation position of the paying-off mark above the support steel plate 6, and hoisting the steel rail 1 on the support steel plate 6 according to the track installation position.
Fig. 2 and 3 depict overall the construction of a scenario of a spaced-support ground track laying method. Specifically, fig. 2 is a schematic structural view of a space-supported 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 track mounting location includes a track center line and a track edge line. That is, the center line and the edge line of the rail are ejected with ink lines above the respective support steel plates 6. Then the steel rail 1 is hung on each supporting steel plate 6, and after the edges are aligned, the bottom plates of the rail pressing devices are welded on the supporting steel plates 6 on the two sides of the rail.
S130, welding the rail pressing device bottom plate 2 on supporting steel plates on 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 bolts fix the rail pressing device cover plate and the steel rail on the rail pressing device bottom plate. The rail pressing devices are symmetrically and uniformly arranged along two sides of the steel rail at a distance of 500-600 mm. The rail pressing device is characterized in that a T-shaped slot hole is formed in the rail pressing device bottom plate, the rail pressing device bolt penetrates through the T-shaped slot hole, and the bolt head of the rail pressing device bolt is sunk in the slot hole.
That is, the rail pressing device bottom plate and the rail pressing device cover plate are provided with opposite through holes, the rail pressing device bolts penetrate upwards from the rail pressing device bottom plate, and the rail pressing device bolts are fastened at the rail pressing device cover plate. Since the rail anchor plate is welded to the rail underlying it, the head of the anchor bolt must be countersunk into the interior of the anchor base. In a 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 the rail pressing device bolt. During installation, the screw rod of the rail pressing device bolt passes through the stepped hole, and the head of the rail pressing device bolt is accommodated on the stepped platform, so that 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 firmly welding the rail pressing device bottom plate, press the rail pressing device apron, screw the rail pressing device bolt of rail pressing device apron with the hand, have certain clearance between rail and each supporting steel sheet this moment. The rail pressing device cover plate and the rail pressing device bottom plate are preinstalled by manually tightening the bolts, so that a gap is reserved between the steel rail and the supporting steel plate.
In a specific implementation process, an elastic backing plate can be arranged between the steel rail and the supporting steel plate, unbalance caused by a small gap can be eliminated through the arrangement of the elastic backing plate, and buffering can be further increased to prolong the service life of the steel rail.
And S140, removing the first fastening nut 3, and fastening the rail pressing device bolt until the steel rail 1 is pressed with the supporting steel plate 6. That is, the fastening nuts above the supporting steel plate 6 are loosened, and then the rail clamp bolts are further tightened with a wrench or the like, eliminating 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 performed after the steel rail is installed and aligned. Namely, after the supporting 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 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 sliding of the rail pressing devices with uneven pavement is avoided. Multiple adjustment procedures for installing the steel rail are saved, and the track laying efficiency is improved.
And S150, adjusting the adjusting nut 4 until the top surface of the steel rail 1 is on the horizontal plane with the set height.
Specifically, adjusting the adjusting nut 4 until the top surface of the rail 1 is on the horizontal plane of the set height includes providing an electronic level on the top surface of the rail and detecting the height of the top surface of the rail by a precision level, and adjusting the adjusting nut until the top surface of the rail is on the horizontal plane of the set height.
And S160, completely fastening the foundation bolt by using the first fastening nut 3.
After the anchor bolt is completely fastened with the first fastening nut, a second fastening nut for reinforcement is installed above the first fastening nut. That is, by adjusting the adjusting nut 4 below the supporting steel plate 6, after the elevation of the top surface of the steel rail reaches the design requirement, the fastening nut above the supporting steel plate 6 is screwed down and the backup nut is pressed down to form double-nut fixation. That is, the adjustment of the rail and the supporting steel plate is performed separately from the pre-adjustment and the re-adjustment.
In summary, the invention relates to a method for paving a ground track with a space support, which has the technical effects of improving the installation accuracy of the track by changing the installation sequence, eliminating the installation error of a support steel plate through the fastening of a rail pressing device and the self rigidity of the track and then performing secondary grouting.
However, it will be appreciated by those skilled in the art that various modifications may be made to the above-described spaced-support floor track laying method of the present invention without departing from the teachings of the present invention. Accordingly, the scope of the invention should be determined from the following claims.
