[0051] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0052] The directional terms in the description of this application are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting this application.

[0053] One aspect of the present application provides a structure for treating ballastless track boss damage, as shown in FIG. Figure 5 The governance structure includes a bottom plate 1, a track plate 2, an original boss 3 and a new boss 4. The track plate 2 is arranged on the bottom plate 1, and an opening groove 21 is formed at both ends of the track plate 2, and a frame groove 22 is formed between the two ends. The original boss 3 is connected to the base, arranged between two adjacent track plates 2, and located in the space surrounded by two adjacent opening grooves 21. The new boss 4 is formed in the frame groove 22, and the new boss 4 is connected to the bottom plate 1.

[0054] Specifically, when the ballastless track is built, an original boss 3 is provided between two adjacent track plates 2, and a frame groove 22 is formed between the two ends of the track plate 2. For example, if the track plate 2 is an I-type track plate 2, the original boss 3 is used to limit the adjacent track plate 2. However, as the operation time of the ballastless track gradually increases, the original boss 3 is affected by impact loads, etc., and gradually cracks, breaks, etc., weakening or even losing the limiting and fixing function of the track plate 2, which is not conducive to maintaining the overall stability of the track structure. If it is not promptly treated, it will cause certain safety hazards to railway operations.

[0055] The management structure provided in the present application utilizes the frame groove 22 in the structure of the track plate 2 itself, and arranges a new boss 4 in the frame groove 22, thereby dispersing the force borne by the original boss 3, compensating for the insufficient force borne by the original boss 3, and effectively improving the safety performance of track operation caused by damage to the original boss 3 of the ballastless track. The structure is simple, the construction efficiency is high, and it does not affect the normal operation of the railway.

[0056] In one embodiment, see Figure 1 to Figure 5The governance structure provided by the present application further includes a filling body 5, which is filled around the new boss 4 and is located between the new boss 4 and the track plate 2. By arranging the filling body 5 between the new boss 4 and the track plate 2, the track plate 2 can be better limited, the impact between the track plate 2 and the new boss 4 can be reduced, and the service life of the original boss 3 can be increased.

[0057] In one embodiment, see Figure 3 In the governance structure provided in the present application, the filling body 5 includes a foam layer 51 and a buffer layer 52. The foam layer 51 is filled on the base plate 1, and the top surface height of the foam layer 51 is higher than or equal to the bottom surface height of the track plate 2. The buffer layer 52 is filled on the foam layer 51. Specifically, the buffer layer 52 has a certain elasticity. When there is a tendency for impact between the new boss 4 and the track plate 2, the buffer layer 52 can absorb part of the impact potential energy between the two, thereby reducing damage to the new boss 4 and the track plate 2. By providing the foam layer 51, the buffer layer 52 can be prevented from gradually entering the bottom of the track plate 2 during long-term use, so as to ensure that the buffer layer 52 is always located between the track plate 2 and the new boss 4 to play its due role. Preferably, the height of the foam layer 51 is equal to the bottom surface height of the track plate 2, so that more buffer layers 52 can be filled, so that the buffer layer 52 provides a better buffering effect for the track plate 2 and the new boss 4.

[0058] Furthermore, in one embodiment, the buffer layer 52 includes a resin bag and a resin, and the resin is cast and formed in the resin bag. It is understandable that artificially preparing a resin material with good elasticity is of great significance to alleviating the impact load between the new boss 4 and the track plate 2. The resin is generally formed by weathering after casting, so a resin bag is provided and the resin with fluidity is cast in the resin bag, so that the shape and position of the resin during the forming process can be better controlled, and the resin can be prevented from flowing into unnecessary spaces such as the bottom of the track plate 2, resulting in waste of resin.

[0059] In one embodiment, in the treatment structure provided by the present application, the filling body 5 further includes a waterproof layer (not shown) for preventing rainwater from penetrating into the buffer layer 52. Specifically, the waterproof layer is filled on the buffer layer 52 between the new boss 4 and the track plate 2. By providing the waterproof layer, rainwater can be effectively prevented from entering the buffer material such as resin, thereby causing adverse effects on the performance of the resin, that is, the various performances of the buffer material such as resin are effectively guaranteed.

[0060] In one embodiment, in the governance structure provided by the present application, the new boss 4 includes a steel frame (not shown) and a boss body (not shown). The steel frame is connected to the bottom plate 1, and the boss body is formed by pouring concrete on the steel frame. It can be understood that the reinforced concrete material itself is inexpensive, has high strength after forming, and is convenient and fast when cast on site, so that while ensuring the strength of the new boss 4, it can also ensure the speed of construction and prevent affecting the normal operation of the railway.

[0061] In one embodiment, see Figure 1 and Figure 2 In the governance structure provided by the present application, the number of new bosses 4 in each frame groove 22 is one, and the two ends of the new bosses 4 along the extension direction of the ballastless track are adjacent to the track plate 2. It can be understood that when the size of the frame groove 22 on the track plate 2 is small, only one new boss 4 can be set in the frame groove 22. At this time, the two ends of the new bosses 4 along the extension direction of the ballastless track provide a certain limit effect on the track plate 2 to prevent the track plate 2 from moving.

[0062] Optionally, in one embodiment, see Figure 4 and Figure 5 In the governance structure provided by the present application, the number of new bosses 4 in each frame groove 22 is two, which are respectively arranged on both sides of the frame groove 22 along the extension direction of the ballastless track. It can be understood that when the length of the frame groove 22 of the track plate 2 is large, it is not necessary to arrange new bosses 4 in the entire frame groove 22, but only to arrange new bosses 4 on both sides of the frame groove 22 along the extension direction of the ballastless track to meet the limit function of the track plate 2, thereby saving construction materials and reducing the construction period.

[0063] The second aspect of the embodiment of the present application provides a method for treating ballastless track boss damage, see Figure 6 , governance methods include:

[0064] S10, constructing a new boss 4 connected to the base plate 1 in the frame groove 22 of the track plate 2;

[0065] S20, repairing the original bosses 3 in the open grooves 21 at both ends of the track plate 2.

[0066] Specifically, the frame groove 22 of the track plate 2 is used to construct a new boss 4 in the frame groove 22 to limit the track plate 2. After the new boss 4 is constructed, since the new boss 4 can withstand a certain impact force, the new boss 4 can first withstand the impact load of the track plate 2, and the original boss 3 in the open grooves 21 at both ends of the track plate 2 is repaired. After the original boss 3 is repaired, the new boss 4 and the original boss 3 work together.

[0067] The method for treating the damaged ballastless track boss provided in the embodiment of the present application provides a certain limiting effect on the track plate 2 by setting a new boss 4 in the frame groove 22 of the track plate 2, and then repairing the damaged original boss 3. After the repair is completed, the new boss 4 and the original boss 3 together limit the track plate 2. The treatment method is carried out during the railway's idle time, and the construction is simple and fast. It can effectively solve the problem of damage and failure of the original boss 3, and does not affect the normal operation of the railway.

[0068] In one embodiment, see Figure 7 In the treatment method provided in the present application, S10, the step of constructing a new boss 4 connected to the base plate 1 in the frame groove 22 of the track plate 2, comprises:

[0069] S11, implanting a steel bar body on the bottom plate 1 in the frame groove 22 of the track plate 2;

[0070] S12, fixing the first template in the frame groove 22 to surround the steel bar body;

[0071] S13, pouring concrete in the first template to form a new boss 4;

[0072] S14, removing the first template;

[0073] S15, filling the filling body 5 between the new boss 4 and the track plate 2.

[0074] Specifically, the new boss 4 is formed by pouring concrete on the steel bar body. During pouring, in order to prevent the concrete from flowing into unnecessary spaces such as the bottom of the track plate 2, a first template is provided to limit the flow direction of the concrete and prevent the loss of the concrete.

[0075] Preferably, the steel bar body includes vertical bars (not shown) and stirrups (not shown). Holes are drilled on the base plate 1 in the frame groove 22, and the vertical bars are implanted into the track plate 2 using a reinforcing bar glue, and the stirrups are tied to the vertical bars. Preferably, the diameter of the drilled hole is 32 mm, the depth is 220 mm, the diameter of the vertical bar is 25 mm, the length is 435 mm, and the hardness is 400 HRB. The stirrups are made of steel bars with a diameter of 12 mm and a hardness of 400 HRB. The steel bar body formed in this way has higher strength, so that the strength of the new boss 4 formed after pouring concrete is also higher.

[0076] After pouring concrete, when the concrete is fixed and formed, preferably, after the concrete strength reaches 10 MPa, the first template is removed and the concrete is polished to make the outer surface of the formed concrete smooth. A gap is formed between the new boss 4 and the track plate 2. By filling the filler 5 between the new boss 4 and the track plate 2, the impact load between the track plate 2 and the new boss 4 can be effectively reduced.

[0077] In one embodiment, in the treatment method provided by the present application, S15, the step of filling the filling body 5 between the new boss 4 and the track plate 2, comprises:

[0078] Fill the foam layer 51 on the bottom plate 1 between the new boss 4 and the track plate 2;

[0079] Placing the resin bag on the foam layer 51;

[0080] Pouring resin into the resin bag;

[0081] Apply sealant between the new boss 4 and the track plate 2 for waterproofing.

[0082] Specifically, the resin is cast, and a foam layer 51 is filled on the bottom plate 1 between the new boss 4 and the track plate 2 to prevent the resin from flowing into the bottom of the track plate 2 during the casting process, causing certain waste. In the subsequent use process, in order to prevent rainwater from entering and affecting the performance of the resin, a sealant is applied between the new boss 4 and the track plate 2 to waterproof the resin. Preferably, the sealant is a silicone sealant.

[0083] In one embodiment, see Figure 7 In the treatment method provided in the present application, S20, the step of repairing the original bosses 3 in the open grooves 21 at both ends of the track plate 2, comprises:

[0084] S21, chiseling away the damaged concrete of the original boss 3 and the filling body 5 around the original boss 3;

[0085] S22, inspect and replant the damaged steel bars of the original boss 3;

[0086] S23, installing the second template to surround the original boss 3;

[0087] S24, pouring concrete in the second template to repair the original boss 3;

[0088] S25, removing the second template;

[0089] S26, filling a new filling body 5 around the original boss 3.

[0090] Specifically, before repairing the original boss 3, it is necessary to first chisel out the filling body 5 around the original boss 3 and the damaged concrete of the original boss 3 to facilitate subsequent construction. In the process of chiseling out the damaged concrete of the original boss 3, it is necessary to completely chisel out the damaged concrete and extend a little toward the middle direction of the original boss 3 to completely expose the new surface of the concrete. In the process of replanting the steel bars, it is necessary to adjust the position of the steel bars, extend the steel bars of insufficient length by welding, and replant the steel bars as needed so that the steel bars in the original boss 3 meet the relevant design requirements.

[0091] After installing the second formwork, the remaining concrete on the original boss 3 needs to be sprinkled with water or coated with an interface agent, and then the polymer concrete is configured and poured in proportion. After the concrete solidifies and the strength reaches the relevant requirements, the second module is removed and the solidified concrete is polished and cleaned.

[0092] S26, the step of filling a new filling body 5 around the original boss 3 specifically comprises: firstly installing a foam board and a resin bag at the bottom of the base plate 1, the top surface of the foam board should be higher than or equal to the bottom surface of the track plate 2, and then configuring a resin material with good elasticity in proportion, stirring it evenly and pouring it into the resin bag.

[0093] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0094] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
