Problems solved by technology

If the construction quality is not good, on the one hand, it will cause the resin to be not firmly bonded to the convex stopper and the track plate, and the longitudinal displacement between the track plate and the convex stopper will occur after the force is applied; on the other hand, it will cause the filling resin to gel prematurely Loss of flow, insufficient filling, or a large number of air bubbles, resulting in low density and low strength

Embodiment Construction

[0025] see Figure 1 to Figure 4 , the construction method of filling the resin on the convex block of the plate type ballastless track is to paste the perfusion bag (3) with adhesive between the convex block (2) and the track plate (1), and then fill the perfusion bag with the filling resin (5). (3) Perform pouring to make good adhesion between the convex block (2) and the track plate (1). Its construction method is:

[0026] 1. Preparation before pouring: remove garbage, sand, mud and other sundries around the convex stand (2), and dry the water with a dry cloth.

[0027] 2. Stir and mix the perfusion bag adhesive: remove the cover of the perfusion bag adhesive A and B components used for bonding the convex block (2) and the track plate (1), and then stir and mix according to the usage amount, and mix for 3-5 minutes uniform. The adhesive is epoxy resin type, polyurethane resin type or epoxy vinyl resin type, preferably epoxy resin type, and the stirring and mixing equipm...

Abstract

The invention discloses a construction method for filling resin in a convex blocking platform of a plate-type ballastless-free rail. An infusion bag is adhered between the convex blocking platform and a rail plate by using an adhesive and infused with filling resin so that the convex blocking platform and the rail plate are favorably adhered. The construction method comprises the following steps of: preparing before infusion; stirring and mixing the infusion bag and the adhesive; coating the adhesive on the cylindrical surface of the convex blocking platform and the semi-circular curve of the rail plate; mounting a foam cushion; adhering the infusion bag; stirring and mixing the convex blocking platform with the resin; and infusing the resin, solidifying and subsequently processing. The filling resin constructed between the convex blocking platform and the rail plate has favorable adhesive force to concrete members, resists UV irradiation, hydrothermal aging and chemical corrosion, and has a certain elasticity and mechanical strength. The construction method is simple and convenient to operate, thereby being suitable for the mass construction of plate-type ballastless-free rails.

Description

technical field [0001] The invention relates to a resin filling construction method, in particular to an on-site construction process for resin filling of track slabs and convex retaining platforms of railway slab-type ballastless tracks. It belongs to the technical field of rail transit. Background technique [0002] CN200610005267.3 and CN200610005569.2 disclose a kind of slab ballastless track for 350km / h high-speed railway and urban track, its structure includes a base located at the foundation, and a convex stop is built on the base, between the convex stops Place the track plate, a CA mortar adjustment layer is provided between the track plate and the base, and it is firmly connected with the track plate. The middle of the longitudinal ends of the track plate is provided with a semicircular gap that matches the convex stop on the base. Resin mortar material is poured between the convex block and the gap. But this patent request does not illustrate the construction pr...
