In an embodiment, referring to fig. 1 and 2, in the treatment structure provided by the present application, the number of the new bosses 4 in each frame groove 22 is one, and both ends of the new bosses 4 along the extending direction of the ballastless track are adjacent to the track slab 2. It can be understood that when the size of the frame groove 22 on the track slab 2 is small, only one new boss 4 may be arranged in the frame groove 22, and at this time, the two ends of the new boss 4 along the extending direction of the ballastless track provide a certain limiting effect for the track slab 2, so as to prevent the track slab 2 from moving.
Optionally, in an embodiment, referring to fig. 4 and 5, in the treatment structure provided by the present application, the number of the new bosses 4 in each frame slot 22 is two, and the new bosses are respectively disposed on two sides of the frame slot 22 along the extending direction of the ballastless track. It can be understood that when the length of the frame groove 22 of the track slab 2 is large, the new boss 4 does not need to be arranged in the whole frame groove 22, and the limit effect on the track slab 2 can be met only by arranging the new bosses 4 in the frame groove 22 along the two sides of the extension direction of the ballastless track, so that the construction material is saved, and the construction period is shortened.
A second aspect of the embodiment of the present application provides a method for treating a ballastless track boss damage, please refer to fig. 6, where the method includes:
s10, constructing and forming a new boss 4 connected with the bottom plate 1 in the frame groove 22 of the track slab 2;
and S20, repairing the original bosses 3 in the open grooves 21 at the two ends of the track plate 2.
Specifically, a new boss 4 is constructed and formed in the frame groove 22 by using the frame groove 22 of the track plate 2 itself, so as to limit the track plate 2. After the construction of the new boss 4 is completed, because the new boss 4 can bear a certain impact force, the new boss 4 can bear the impact load of the track plate 2, the original bosses 3 in the open grooves 21 at the two ends of the track plate 2 are repaired, and after the original bosses 3 are repaired, the new boss 4 and the original bosses 3 work together.
According to the method for treating the damage of the ballastless track boss, the new boss 4 is arranged in the frame groove 22 of the track slab 2, a certain limiting effect is provided for the track slab 2, then the damaged original boss 3 is repaired, and after the repair is completed, the new boss 4 and the original boss 3 limit the track slab 2 together. The treatment method is carried out by utilizing the window-opening time of the railway, the construction is simple and quick, the problem of damage and failure of the original boss 3 can be effectively solved, and the normal operation of the railway is not influenced.
In an embodiment, referring to fig. 7, in the treatment method provided by the present application, the step of constructing and forming a new boss 4 connected to the base plate 1 in the frame slot 22 of the track slab 2 at S10 includes:
s11, implanting a steel bar body on the bottom plate 1 in the frame groove 22 of the track slab 2;
s12, fixing the first template in the frame groove 22 and arranging a steel bar body in an enclosing manner;
s13, pouring concrete in the first template to form a new boss 4;
s14, removing the first template;
and S15, filling the filling body 5 between the new boss 4 and the track plate 2.
Specifically, the new boss 4 is formed by pouring concrete on the reinforcement body, and when pouring, in order to prevent the concrete from flowing into unnecessary spaces such as the bottom of the track slab 2, a first formwork is arranged to limit the flow direction of the concrete and prevent the loss of the concrete.
Preferably, the reinforcing body includes vertical bars (not shown) and stirrups (not shown). And drilling holes on the bottom plate 1 in the frame groove 22, implanting vertical ribs into the track plate 2 by using bar-implanting glue, and binding the stirrups on the vertical ribs. Preferably, the bore hole is 32mm in diameter and 220mm deep, the vertical ribs are 25mm in diameter, 435mm in length and 400HRB in hardness. The stirrups are made of reinforcing steel bars with the diameter of 12mm and the hardness of 400 HRB. The reinforcement body thus formed has a higher strength, so that the new boss 4 formed after the concrete is poured is also higher in strength.
After the concrete is poured and fixed and shaped, the first template is preferably removed after the strength of the concrete is in the range of 10MPa, and concrete grinding is performed to flatten the outer surface of the shaped concrete. A gap is formed between the new boss 4 and the track plate 2, and the filler 5 is filled between the new boss 4 and the track plate 2, whereby the impact load between the track plate 2 and the new boss 4 can be effectively reduced.
In an embodiment, in the treatment method provided by the present application, the step of filling the filling body 5 between the new boss 4 and the track slab 2 at S15 includes:

placing a resin bag on the foam layer 51;
pouring resin into the resin bag;
and (4) coating a sealant between the new boss 4 and the track slab 2 for waterproof treatment.
Specifically, for the casting molding, the foam layer 51 is filled on the bottom plate 1 between the new boss 4 and the track plate 2, so as to prevent the resin from flowing into the bottom of the track plate 2 during the casting process, which causes a certain waste. In the later use process, in order to prevent rainwater from entering and affecting the performance of the resin, a sealant is coated between the new boss 4 and the track plate 2 to perform waterproof treatment on the resin, and preferably, the sealant is a silicone sealant.
In an embodiment, referring to fig. 7, in the treatment method provided by the present application, the step of S20 repairing the original bosses 3 in the open slots 21 at the two ends of the track slab 2 includes:
s21, chiseling damaged concrete of the original boss 3 and the filler 5 around the original boss 3;
s22, checking and replanting the damaged steel bar of the original boss 3;
s23, installing a second template to enclose the original boss 3;
s24, pouring concrete in the second template to repair the original boss 3;
s25, removing the second template;
and S26, filling a new filling body 5 around the original boss 3.
Specifically, before repairing the original boss 3, the filler 5 around the original boss 3 and the concrete damaged by the original boss 3 need to be chiseled off first to facilitate subsequent construction, and in the process of chiseling the damaged concrete of the original boss 3, a little of the filler needs to extend towards the middle direction of the original boss 3 on the basis of completely chiseling the damaged concrete to enable the concrete to completely expose a new surface. In the process of replanting the reinforcing steel bar, the position of the reinforcing steel bar needs to be adjusted, the reinforcing steel bar with insufficient length is prolonged by welding, and the reinforcing steel bar is replanted as required, so that the reinforcing steel bar in the original boss 3 meets the relevant design requirements.
After the second template is installed, the residual concrete of the original boss 3 needs to be sprayed with water to wet or coated with an interface agent, then polymer concrete is prepared and poured in proportion, after the strength of the solidified concrete reaches relevant requirements, the second module is detached, and the solidified concrete is polished and cleaned.
S26, filling a new filling body 5 around the original boss 3, which specifically comprises the following steps: firstly, a foam board and a resin bag are arranged at the bottom of a bottom board 1, the top surface of the foam board is higher than or equal to the bottom surface of a track board 2, then resin materials with better elasticity are prepared in proportion, and the resin bag is poured after the resin materials are uniformly stirred.
