[0002] The elastic support block type ballastless roadbed is a vibration-damping roadbed with the characteristics of good elasticity, less maintenance, easy replacement, mature component manufacturing and on-site construction technology, etc. It is widely used in long tunnels of trunk lines. The elastic support block type ballastless roadbed is generally composed of elastic support blocks and concrete roadbed plates, among which the elastic support blocks include concrete support blocks and rubber boots.

[0003] The rubber boot of the elastic support block can adopt an integrated structure, and the entire boot is vulcanized and formed in one step, with fewer parts and convenient installation. The patent with publication number CN204080553U discloses an elastic boot for a ballastless track support block, including an integrated boot body. The boot body is made of rubber or polyurethane material, and is composed of a bottom plate and four side walls. It is box-shaped and wrapped around the side and bottom of the support block, embedded in the concrete roadbed, and isolates the support block from the concrete roadbed around it. However, the elastic boot of this structural form is not easy to demold during the vulcanization molding process, and because the boot is only wrapped around the side and bottom of the support block, it is easy for water to enter from the gap between the side of the support block and the side wall of the boot. It is only used in tunnel sections, which limits its use scenario.

[0004] Therefore, it is necessary to optimize the structure of the overshoe to overcome the above-mentioned defects. Summary of the invention

[0038] In a specific implementation, Figure 1 The direction from top to bottom is defined as the longitudinal direction. Figure 1 The direction from left to right is defined as landscape.

[0039] like Figure 1-3 The utility model provides an integrated overshoe, which is suitable for ballastless track sections, and includes an overshoe body 1. The overshoe body 1 includes a large pad 11 at the bottom and side walls 12 around the top of the large pad 11. The large pad 11 and the side walls 12 are an integrally formed structure and can be vulcanized by rubber materials. The overshoe body 1 is covered on the bottom and side of the concrete support block 2, and the structural parameters match the concrete support block 2. According to the side form of the concrete support block 2, the side wall 12 of the overshoe body 1 can be set vertically or obliquely.

[0040] The overshoe body 1 is divided into three parts, namely the left part, the middle part and the right part. The inner wall of the overshoe body 1 in the middle part is provided with a longitudinal groove 13, and the longitudinal groove 13 is longitudinally connected on the large pad 11 in the middle part and the side walls 12 on the front and rear sides. The inner walls of the overshoe body 1 in the left and right parts are provided with transverse grooves 14, and the transverse groove 14 in the left part is transversely connected on the large pad 11 in the left part and the side wall 12 on the left side, and the transverse groove 14 in the right part is transversely connected on the large pad 11 in the right part and the side wall 12 on the right side. The left inner wall and the right inner wall of the side walls 12 on the front and rear sides are planes. The depth of each groove is ≤2cm, and the cross section of the groove can be rectangular, square, etc. On the large pad 11, there is a horizontal gap between the longitudinal groove 13 and the transverse groove 14.

[0041] In addition, the top surface of the overshoe body 1 is provided with an outwardly extending enlarged edge, and the top surface of the enlarged edge is provided with upwardly protruding and circumferentially arranged waterproof protrusions 15.

[0042] like Figure 6 The utility model also provides an elastic support block, which includes the above-mentioned integrated overboot and a concrete support block 2. The top periphery of the concrete support block 2 is provided with an outwardly extending waterproof edge 21, and the bottom surface of the waterproof edge 21 is provided with a circumferentially arranged waterproof groove 22. After the concrete support block 2 is placed in the integrated overboot, the waterproof edge 21 is located on the top surface of the expanded edge, and the waterproof protrusion 15 is embedded in the waterproof groove 22. The waterproof protrusion 15 and the waterproof groove 22 cooperate with each other to form an annular sealing and waterproof structure at the top between the overboot body 1 and the concrete support block 2. There is no exposed gap at the top between the overboot body 1 and the concrete support block 2, so that water is not easy to enter the overboot body 1. With this structural form, the elastic support block of the utility model can be used not only in tunnel sections, but also in open areas.

[0043] like Figure 4-5 The utility model also provides a mold for an integrated overshoe, and the mold is used to make the above-mentioned integrated overshoe, including a mold box body 3 and a mold tooling.

The mold tooling includes a middle mold tooling 34 and two side mold toolings 35, the middle mold tooling 34 corresponds to the middle overshoe body 1, and the side mold tooling 35 corresponds to the left and right overshoe bodies 1. The front and rear sides and the bottom surface of the middle mold tooling 34 are provided with mold longitudinal convex strips 36 corresponding to the longitudinal grooves 13. One side and the bottom surface of the side mold tooling 35 are provided with mold transverse convex strips 37 corresponding to the transverse grooves 14.

[0044] After the integrated boot is vulcanized, the middle mold tooling 34 can be lifted upwards first. Since the grooves and convex strips of this part are arranged longitudinally, the convex strips slide out vertically from the grooves when lifted upwards, making it easy to lift. Afterwards, since there is a horizontal gap between the longitudinal grooves 13 and the transverse grooves 14 on the large pad 11, the side mold tooling 35 can be slid toward the middle to demould.

[0045] In addition, the mold box body 3 includes a bottom box 31 and a cover body 32 . A protrusion forming groove 33 is arranged around the edge of the bottom surface of the cover body 32 for forming the waterproof protrusion 15 .

[0046] The utility model optimizes the structural appearance of the overshoe on the basis of the existing integrated overshoe, adopts the design of inner groove, and is equipped with a slidable mold tooling to solve the problem of the difficulty of demoulding the integrated overshoe. An annular convex structure is designed on the top of the overshoe, and the structure of the concrete support block is correspondingly optimized to solve the problem of water inflow into the overshoe structure, avoid water inflow into the overshoe, and extend the service life of the overshoe. The utility model has good integrity, simple manufacturing process, and convenient on-site construction and replacement.
