Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical solution in the embodiment of the present invention is explicitly described, it is clear that described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not having
Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
Fig. 1 is the flow chart of rail yard track switch reinforcement means provided in an embodiment of the present invention, as shown in Figure 1, this method
Include: step 1, D type construction beam stringer is set in track switch two sides, and the D type construction beam stringer is supported using borehole column；
Step 2, switch tie bottom be fixedly installed D type construction beam crossbeam, and the both ends of the D type construction beam crossbeam respectively with it is described
The D type construction beam stringer of track switch two sides contacts；Step 3, by bracket and connecting plate by the D type construction beam stringer and institute
State the end fastening of D type construction beam crossbeam.
Wherein, bracket refers to the local structure of cantilever end and drop in beam end, also known as corbel.The effect of bracket is linking cantilever
Beam and drop in beam, and transmit the load from drop in beam.Herein due to the mutual overlap joint of beam, centre there is provision of force-transmission support seat to pass
Biggish vertically and horizontally counter-force is passed, therefore bracket height has weakened to the half less than deck-molding, but transmitted again biggish perpendicular
Straight and horizontal reacting force, this just makes it the weak part in superstructure.
Specifically, D type construction beam stringer 1 is set in track switch two sides combined with Figure 1 and Figure 2, and D is supported using borehole column 8
Type construction beam stringer 1, for example, the borehole column 8 manually built up supports D type construction beam stringer 1, track switch needs at general one
Build 4 borehole columns 8.Then 4 bottom of switch tie setting D type construction beam crossbeam 2 is crossed, that is, D type construction beam crossbeam 2 passes through
The bottom of entire switch tie 4 is then not required to that entire track switch can be reinforced track switch progress subregion, and can be adapted for different shaped
Number track switch.Then, which is tightened together with switch tie 4.
As described in Figure 3, the end of D type construction beam crossbeam 2 and D type construction beam stringer 1 are connected to connecting plate 10
Together, for example, being connected to the end of connecting plate 10 and D type construction beam crossbeam 2 and D type construction beam stringer 1 by bolt
Together.And bracket 4 is arranged in the end of D type construction beam crossbeam 2 and the junction of D type construction beam stringer 1, for example, will
Two right-angle sides of bracket 4 pass through bolt respectively and are connected with the end of D type construction beam crossbeam 2 and D type construction beam stringer 1, into
And improve the reliability of entire track switch.
In embodiments of the present invention, by the way that D type construction beam stringer is arranged in track switch two sides, switch tie bottom setting D is crossed
Type construction beam crossbeam, and be fixedly connected with D type construction beam stringer with D type construction beam crossbeam with connecting plate by bracket,
So that each component connection relationship is solid and reliable in rail yard track switch, safety when train passes through track switch, stationarity ensure that
And comfort；Meanwhile the ruggedized construction good integrity obtained by the rail yard track switch reinforcement means, it is applicable to different shaped
The reinforcing of number track switch.
In addition, pre-embedded bolt 9 can be arranged at the top of borehole column 8, to be fixed on borehole column 8 using the pre-embedded bolt 9
The lower section of D type construction beam stringer 1, to play a supporting role.Can also the top of D type construction beam stringer 1 and borehole column 8 it
Between rubber pad is set, to prevent D type construction beam stringer 1 from sliding with borehole column 8.
On the basis of the above embodiments, after the step 3 further include: the D type construction beam crossbeam 2 with
It is laid with steel plate 15 between the switch tie 4, and the D type construction beam crossbeam 2 is fixedly connected with the steel plate 15；And institute
The both ends for stating switch tie 4 are respectively provided with limit angle steel, and the switch tie 4 fixation is limited on the steel plate 15.

Upper setting goat 6, and the goat 6 is fixed on the D type construction beam crossbeam 2 with angle steel 7.
Wherein, goat (switch machine/point machine) is the executing agency of switch control system；With
In conversion locking point tongue or heart rail, the position and state of point tongue or heart rail in supervision interlocking area are indicated.
Specifically, goat 6 is arranged and the goat 6 is fixed on D on D type construction beam crossbeam 2, and with angle steel 7
On type construction beam crossbeam 2, that is, open up bolt hole in the corresponding position of angle steel 7 and D type construction beam crossbeam 2；Then, by angle
Steel 7 is arranged at the lower edge of goat 6, and angle steel 7 is fixedly connected by blending bolt with D type construction beam crossbeam 2, so that turn-out track
Machine 6 is fixed on D type construction beam crossbeam 2.
On the basis of the various embodiments described above, the rail yard track switch reinforcement means, further includes: in the switch tie 14
Insulation board 11 is set between the steel plate 15.Further include: Framed underpass bridge is carried out after the completion of reinforcing, and Framed underpass bridge is completed
After remove ruggedized equipment.
Specifically, insulation board 11 is set between switch tie 14 and steel plate 15, for example, insulation board 11 is plank etc.；That is, branching off
Pillow 14, insulation board 11, steel plate 15 and D type construction beam crossbeam 2 are set gradually under upper, thus make switch tie 14 and steel plate 15 it
Between insulate, the influence to avoid steel plate 15 and D type construction beam crossbeam 2 to switch tie 14 improves the security performance of entire track switch.?
After the completion of reinforcing to rail yard track switch, Framed underpass bridge construction is carried out, Framed underpass bridge removes track strengthening equipment afterwards in place,
Restore route.In addition, above-mentioned construction procedure is only to illustrate technically feasible, the difference of sequence of construction can't be patent right
Limiting factor.
