[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a composite waterstop for railway tunnel construction joints, including a base 1, a protrusion 2 is fixedly connected to one side of the outer wall of the base 1, a groove 3 is opened inside the base 1, the outer wall of the protrusion 2 is slidably connected to the inner wall of the groove 3, a edging strip 4 is fixedly connected to the outer wall of the base 1, a groove 2 5 is opened inside the base 1, the outer wall of the edging strip 4 is slidably connected to the inner wall of the groove 2 5, a grouting pipe 10 is fixedly connected to the inside of the base 1, a connecting groove 11 is opened inside the base 1, one end of the connecting groove 11 is fixedly connected to the inside of the grouting pipe 10, and a fixing component is arranged inside the base 1.
[0024] Specifically, by connecting the protrusion 2, the edging strip 4 and the groove 1 3 and the groove 2 5 on the side of the base 1, the connection between the bases 1 is made more secure, and the problem of easy breakage at the connection is solved. The filling material is injected into the grouting pipe 10, and the filling material enters the connecting cavity 17 through the connecting groove 1 11 and the connecting groove 2 12, so that the water-stopping performance of the base 1 is higher.
[0025] Reference Figure 1 , Figure 2 and Figure 4 The fixing group includes a fixing bolt 7, the outer wall of the fixing bolt 7 is threadedly connected to the inside of the base 1, a bolt groove 6 is opened inside the base 1, a fixing ring 8 is arranged on the outer wall of the fixing bolt 7, a narrow opening 9 is opened inside the base 1, one side of the outer wall of the fixing ring 8 is attached to the inner wall of the narrow opening 9, an inner metal mesh 14 is fixedly connected to the inside of the base 1, an outer metal mesh 13 is fixedly connected to the inside of the base 1, a connecting groove 2 12 is opened inside the base 1, a connecting cavity 17 is opened inside the base 1, one end of the connecting groove 2 12 is fixedly connected to the inside of the connecting cavity 17, a rubber convex strip 15 is fixedly connected to the upper surface of the base 1, and a rubber convex strip 2 16 is fixedly connected to the inside of the base 1.
[0026] Specifically, the fixing bolt 7 drives the fixing ring 8 to seal the narrow opening 9, and at the same time, the fixing bolt 7 fixes the position of the base 1 to prevent the base 1 from deformation and displacement, thereby achieving the effect of extending the service life of the base 1. The strength of the base 1 is then strengthened by arranging an outer metal mesh 13 and an inner metal mesh 14 inside the base 1, so that the compressive resistance of the base 1 is stronger, thereby achieving the effect of increasing the practicality of the base 1.
[0027] Working principle: When it is necessary to use a composite waterstop for railway tunnel construction joints, first align the protrusion 2 and the edging strip 4 on one side of the substrate 1 with the groove 1 3 and the groove 2 5 on the other side of the substrate 1 to form a double connection. When it is necessary to stop the water on a larger area of the wall, this double connection method can strengthen the connection between the two waterstops to prevent the waterstops from breaking at the connection. Then, by setting the connecting groove 2 12 and the inner metal mesh 14 inside the substrate 1, the sealing material injected into the grouting pipe 10 can enter the connecting cavity 17, so that a sealing structure is formed inside the substrate 1, and a grouting is set inside the substrate 1. The pipeline 10 is convenient for grouting. After the position of the base 1 is fixed, grouting into the base 1 can effectively improve the waterproof performance of the base 1 and extend the service life of the base 1. A bolt groove 6 is provided inside the base 1. The bolt groove 6 is a slot that is wide at the bottom and narrow at the top. When the fixing bolt 7 is nailed into the base 1, the fixing ring 8 will be driven to seal the narrow opening 9, which can prevent the base 1 from deforming, expanding and displacing after long-term use, thereby achieving the effect of increasing the stability of the base 1. The rubber convex strip 15 and the rubber convex strip 2 16 arranged on the outer wall of the base 1 can increase the contact area with the concrete, thereby achieving the effect of increasing stability.
