Example Embodiment

[0088] Example 1

[0089] Reference figure 2 , Which shows the structural schematic diagram of the crack after repairing the crack by the method according to the embodiment of the present invention. figure 2 The black vertical structure at the bottom of the base surface is the crack 4 of the ballastless track. The non-curing rubber asphalt material 3 is added to the crack 4 after cleaning. When the non-curing rubber asphalt material 3 is added Stop adding when the top surface is flush with the base surfaces on both sides of the crack. After the filling is completed, a layer of polyethylene polypropylene fiber 2 with a thickness of 0.7mm is brushed on the top surface of the non-curing rubber asphalt material 3 as an isolation layer, and the length and width of the isolation layer are respectively greater than the length of the crack. And wide, figure 2 The raised part above the middle crack 4 is the isolation layer composed of the brushed polyethylene polypropylene fiber 2. The...

[0092] Reference Figure 4 , Which shows a schematic structural diagram of cracks after cracking is performed on the track bed slab by using the method in an embodiment of the present invention. Figure 4 The two black vertical structures at the bottom of the base surface of the middle groove are cracks 4. The non-curing rubber asphalt material 3 is added to the cracks 4 after cleaning. When the added non-curing rubber asphalt material 3 is When the surface is flush with the groove base surface on both sides of the crack 4, stop adding, use silicone sealant to seal the crack 4, and then apply a layer of thickness to the surface of the added non-curing rubber asphalt material 3 Polyethylene polypropylene fiber 2 of 0.7 mm is used as the isolation layer, and epoxy resin 5 with a thickness of 0.2 mm and a width of 100 mm is brushed on the two sides adjacent to the isolation layer. After spraying experiments, it is found that when spraying directly, there is no w...

[0093] Example 3

[0094] When repairing the expansion joints of the high-speed railway ballastless track, in the cleaned expansion joints, the expansion joints are first sealed with silicone sealant, and then the non-curing rubber asphalt material is added. Stop adding when the top surface of the non-cured material is flush with the base surfaces of the grooves on both sides of the crack, and then lay a layer of silicone oil paper with a thickness of 0.3mm as an isolation layer on the surface of the added non-cured material, and brush on both sides next to the isolation layer With an epoxy resin with a thickness of 0.15mm and a width of 100mm, after the adhesive layer is painted, the rubber asphalt waterproof prefabricated coil is quickly pasted on the surface of the isolation layer and the adhesive layer, and then butyl tape is used for the adjacent The lap joints of the rubber asphalt waterproof prefabricated coils are treated with lap joints to complete the maintenance of the...

Abstract

The invention provides a composite material and a method for conducting ballastless track waterproof maintenance by adopting the composite material. The method comprises the steps that a gap of a ballastless track is cleaned, and the cleaned gap is filled with a non-curing rubber asphalt waterproof material; an isolation material is laid on the top face of the non-curing rubber asphalt waterproof material to form an isolation layer; concrete base surfaces on the two sides of the isolation layer are coated with binding materials to form binding layers; after the concrete base surfaces are coated with the binding materials, the surfaces of the binding layers and the isolation layer are coated with rapid hardening rubber asphalt waterproof materials or sticky rubber asphalt waterproof prefabricated coiled materials. According to the composite material and the method for conducting ballastless track waterproof maintenance, the good adhesive force of the gap maintained through the method is ensured, powerful shearing stress caused when a train passes the gap at high speed can be effectively resisted, and the composite material is flexible, can effectively resist concrete vibration caused when the train passes the gap at high speed, is not prone to brittle surface factures, and ensures safety usage of the ballastless track.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a composite material for waterproof maintenance of ballastless track and a method for using the composite material to perform waterproof maintenance of ballastless track. Background technique [0002] The use of trains has brought great convenience to people's travel. At present, ballastless tracks have been widely used in the laying of train tracks. The ballastless track structure mainly includes a concrete support layer and a reinforced concrete track bed slab. The support layer and the track bed slab are constructed independently, the concrete surface of the support layer is roughened within the width of the track bed slab, and the track bed slab is a reinforced concrete structure with continuous construction and no expansion joints. The contact surface between the bottom of the ballast bed slab and the support layer is a rough surface, and there is mutual constraint betwee...
