After the installation of the track steel trough 9 is completed, a first formwork sealing component is installed at the free end of the track steel trough 9 to make the first formwork sealing component closely adhere to the end of the free end of the track steel trough 9. Then, a second formwork sealing component is installed at the connection between two adjacent track steel troughs 9 to seal the gap at the connection between the two track steel troughs 9 and at the same time seal the bottom at the connection between the two track steel troughs 9, so as to form a closed effect at the connection of the first formwork sealing component, the second formwork sealing component and the track steel trough 9. Then, the rail surface protection part 8 is buckled on the top of the rail 10 to protect the top surface of the rail 10. After the sealing is completed, a fluid material is poured into the gap between the track steel trough 9 and the rail 10. The rail 10 is fixed by the track steel trough 9 and the fluid material.

The two first fasteners 6 simultaneously push the second formwork 5 upward, and the first formwork 4 moves upward synchronously until both of the two first fasteners 6 are tightly abutted against the second formwork 5, achieving the effect of sealing the bottom gap between the first formwork 4 and two adjacent track steel troughs 9, then the bottoms of the two adjacent track steel troughs 9 are closed. Then, the length of the formwork sealing strip 7 is set according to the length of the vertical end of the track steel trough 9. The formwork sealing strip 7 is embedded between the gaps of two adjacent track steel troughs 9 along the vertical end of the track steel trough 9. The bottom of the formwork sealing strip 7 is in contact with the top of the first formwork 4, and the formwork sealing strip 7 is perpendicular to the first formwork 4.

[0030] Further, sealing strips 7 can be arranged along the transverse and vertical ends of the track steel groove 9, and the sealing strips 7 are embedded between the gaps at the transverse and vertical ends of two adjacent track steel grooves 9, so that the transverse ends of two adjacent track steel grooves 9 are sealed by the first sealing template 4 and the sealing strips 7 at the same time, improving the sealing effect between two adjacent track steel grooves 9.

[0031] As Figure 1 , Figure 3 shown, the first sealing assembly includes a third sealing template 1 and a second fastener 2. The middle part of the third sealing template 1 is a hollow structure matching the shape of the rail 10. The third sealing template 1 is sleeved on the rail 10, and the third sealing template 1 is in close contact with the free end of the track steel groove 9. The two ends of the second fastener 2 are respectively connected to the track steel grooves 9 on both sides of the rail 10, and the middle part of the second fastener 2 is in close contact with the side of the third sealing template 1 away from the track steel groove 9 to limit the third sealing template 1 between the second fastener 2 and the track steel groove 9.

[0032] In this embodiment, the third sealing template 1 is made of an elastic material, and the hollow structure of the third sealing template 1 is consistent with the size of the rail 10.

The width of the third sealing template 1 is less than the distance between the transverse end parts of the track steel grooves 9 on both sides of the rail 10, and the width of the third sealing template 1 is greater than the distance between the vertical ends of the track steel grooves 9 on both sides of the rail 10. Two fixing buckles 3 are arranged at intervals along the height direction of the vertical end of the track steel groove 9. The two ends of the second fastener 2 are respectively connected to the fixing buckles 3 of the two track steel grooves 9, fastening the third sealing template 1 between the second fastener 2 and the track steel groove 9, so that the third sealing template 1 is in close fit with the vertical end of the track steel groove 9 along the height direction, and the third sealing template 1 is in close fit with the transverse end of the track steel groove 9 along the horizontal direction, and the free end of the track steel groove 9 is sealed by the third sealing template 1 and the second fastener 2.

[0033] In another possible embodiment, the third sealing template 1 is made of a steel plate and includes a first template and a second template. A clamping groove is provided at the bottom of the first template, and a clamping block matching the clamping groove is provided at the bottom of the second template. The first template and the second template are connected through the clamping groove and the clamping block at the bottom. Connection ears are provided at the tops of the first template and the second template, and threaded holes are provided on the connection ears. After the bolts pass through the threaded holes, the first template and the second template can be tightly connected. After the first template and the second template are connected, the middle part is a hollow structure, and the size of the hollow structure matches that of the rail 10. First gaskets are provided on the side walls of the first template and the second template that are in contact with the rail 10 to improve the sealing performance of the fit between the first template, the second template and the rail 10. Second gaskets are provided on one side of the first template and the second template close to the rail groove 9, and the shape of the second gasket matches that of the rail groove 9. The sealing between the first template, the second template and the rail groove 9 is achieved through the second gasket. During use, the first template and the second template are respectively erected vertically on the left and right sides of the rail 10, and then the first template and the second template are moved closer to each other. The bottoms of the first template and the second template are both located below the rail 10. The clamping block at the bottom of the second template is clamped into the clamping groove at the bottom of the first template. Then, the first template and the second template are tightly attached to the left and right sides of the rail 10 through the first gaskets respectively. The first template and the second template are moved towards the rail groove 9 until the second gasket is tightly attached to the rail groove 9. Then, the bolts are passed through the connection ears at the tops of the first template and the second template, and the first template and the second template are tightly connected through the bolts. At this time, both the first template and the second template are tightly attached to the rail 10 and the rail groove 9. The first template and the second template are fastened between the second fastener 2 and the rail groove 9 through the second fastener 2 to improve the stability of the connection between the first template, the second template and the rail groove 9 and the rail 10. Or a connecting member is provided on one side of the first template and the second template close to the rail groove 9. After the first template and the second template are connected, they are connected to the rail groove 9 through the connecting member.

[0034] As Figure 1 , Figure 4 shown, the rail surface protection member 8 is of a U-shaped structure. The width of the rail surface protection member 8 is consistent with the width of the rail 10, and the length of the rail surface protection member 8 matches the length of the rail groove 9. The inner part of the transverse end of the rail surface protection member 8 is in contact with the top of the rail 10, and the vertical end of the rail surface protection member 8 is in contact with the side wall of the rail 10.

[0035] In this embodiment, the rail surface protection member 8 is buckled on the surface of the rail 10. The height of the vertical end of the rail surface protection member 8 is consistent with the height of the top plate of the rail 10. By means of the rail surface protection member 8, when pouring the flowing material, it can be avoided that the flowing material splashes and pollutes the working surface of the rail 10. After the flowing material is poured into the rail steel groove 9, the top of the flowing material contacts the end of the vertical end of the rail surface protection member 8. The length of the rail surface protection member 8 is equal to or greater than the length of the rail steel groove 9.

[0036] The number of the second fasteners 2 is multiple. After the multiple second fasteners 2 cross, they are respectively connected to two fixing buckles 3 along the height direction of the rail steel groove 9 to cross-reinforce the third formwork 1.

[0037] In this embodiment, the second fasteners 2 are rubber bands. The multiple second fasteners 2 are divided into two groups, and the number of each group is the same. The middle part of the first group of second fasteners 2 is located on the top of the rail 10. The two ends of the first group of second fasteners 2 are respectively connected to the fixing buckles 3 near the transverse ends of the rail steel grooves 9 on both sides of the rail 10. The middle part of the second group of second fasteners 2 is located at the bottom of the rail 10. The two ends of the second group of second fasteners 2 are respectively connected to the fixing buckles 3 near the ends of the vertical ends of the rail steel grooves 9 on both sides of the rail 10, so as to realize the cross-reinforcement of the third formwork 1 by the two groups of second fasteners 2.

[0038] In another possible embodiment, a snap ring is provided on one side of the third formwork 1 close to the rail steel groove 9. The snap ring is arranged at the position where the third formwork 1 is close to the fixing buckle 3. One end of the snap ring is a ring structure that can be fastened on the fixing buckle 3, and the other end of the snap ring is fixedly connected to the third formwork 1. After the snap ring is fastened to the fixing buckle 3, it is convenient to limit the movement of the third formwork 1 and make the third formwork 1 closely fit the rail steel groove 9.

[0039] As Figure 3 shown, the top of the third formwork 1 is open, which is convenient for sleeving the third formwork 1 on the rail 10.

[0040] The third formwork 1 is made of EPE with a thickness of 40 mm.

[0041] In this embodiment, the top of the third formwork 1 is open, which is convenient for the side with the hollow structure of the third formwork 1 to pass through the rail 10 from the bottom of the rail 10, so that the parts of the third formwork 1 on both sides of the rail 10 are closely attached to the rail steel groove 9. And due to the elastic material of the third formwork 1, the second fasteners 2 are bypassed around the rail 10 and then connected to the fixing buckles 3, and the elasticity of the second fasteners 2 is used to improve the tightness of the fit between the third formwork 1 and the rail steel groove 9.

[0042] The sealing strip 7 is an elastic rubber strip.

[0043] In this embodiment, the sealing strip 7 is made of EPE. By utilizing the elastic characteristics of the sealing strip 7, the sealing strip 7 is embedded in the gap between two adjacent track steel grooves 9 to improve the sealing performance of the track steel grooves 9.

[0044] On one side of the vertical ends of the rail surface protection members 8 facing each other, elastic fasteners are provided to facilitate clamping the rail surface protection members 8 on the top of the rail 10.

[0045] The rail surface protection members 8 are made of stainless steel.

[0046] In this embodiment, the rail surface protection members 8 are clamped on the rail 10 by the elastic fasteners at the vertical ends to prevent the rail surface protection members 8 from moving during the pouring of flowing materials.

[0047] During use, after the track steel grooves 9 are installed, if both ends of the track steel grooves 9 are free ends, third sealing templates 1 are installed at both ends of the track steel grooves 9. The third sealing templates 1 are sleeved on the rail 10, and the second fasteners 2 are used to make the third sealing templates 1 closely fit with the ends of the track steel grooves 9 to achieve the sealing of the two free ends of the track steel grooves 9. If one end of the track steel grooves 9 is a free end, a third sealing template 1 is installed at the end of the free end of the track steel grooves 9. The hollow structure of the third sealing template 1 is closely attached to the rail 10, and the inner side wall of the third sealing template 1 is closely attached to the free end of the track steel grooves 9. Then the second fasteners 2 are divided into two groups, which respectively bypass the top and bottom of the rail 10 and then cross each other, and are respectively connected to the fixed buckles 3 at the end of the track steel grooves 9 close to the transverse end and the vertical end. After the second fasteners 2 are connected to the fixed buckles 3, the second fasteners 2 are in a stressed and tightened state, achieving the close fitting of the third sealing template 1 on the track steel grooves 9 and completing the sealing of the free end of the track steel grooves 9. Then the first sealing template 4 is placed on the second sealing template 5, and the first sealing template 4 and the second sealing template 5 are jointly placed at the gap under the connection end of two adjacent track steel grooves 9. The two first fasteners 6 are respectively located at both ends of the second sealing template 5 along the length direction. The first fasteners 6 are inserted from the gap between the second sealing template 5 and the track bed 11 and tamped tightly. The sealing strip 7 is used to block the gap at the connection end of two adjacent track steel grooves 9, and the sealing strip 7 is embedded in the gap to achieve the sealing of the connection end of the track steel grooves 9. Finally, the rail surface protection members 8 are buckled on the top of the rail 10 to prevent the top surface of the rail 10 from being polluted by flowing materials during the pouring process. Then the sealing of the pouring area of the track steel grooves 9 is completed. After the gap between the track steel grooves 9 and the rail 10 is poured, the first sealing assembly, the second sealing assembly and the rail surface protection members 8 are removed, and the cycle continues to the next place for use. Through the first sealing assembly, the second sealing assembly and the rail surface protection members 8, the problem of difficult sealing in the contour area of the rail 10 is overcome, the appearance effect of the construction finished product is improved, and at the same time the construction efficiency is improved.
