Slab ballastless track self-compacting concrete grouting device and method

Abstract

The invention discloses a slab ballastless track self-compacting concrete grouting device and method. The slab ballastless track self-compacting concrete grouting device comprises a transfer storage hopper. A grouting hopper is arranged at a discharging port of the transfer storage hopper. The grouting hopper is connected with a grouting opening of a concrete formwork. The grouting hopper comprises a conical barrel and a rectangular hopper body. The conical barrel is arranged on the rectangular hopper body. The rectangular hopper body is connected with a discharging port of the conical barrel. The discharging port of the transfer storage hopper is connected with a discharging pipe. The discharging end of the discharging pipe is arranged above the conical barrel. The rectangular hopper body is arranged on the side portion of the concrete formwork. The side, facing the concrete formwork, of the rectangular hopper body is provided with a discharging port. The grouting port is formed in the side, close to the rectangular hopper body, of the concrete formwork. By the adoption of the slab ballastless track self-compacting concrete grouting device and method, the grouting speed is increased, and the grouting quality is better.

Description

technical field [0001] The invention relates to a self-compacting concrete pouring device for a slab-type ballastless track slab and a pouring method thereof, and is especially suitable for pouring construction of a CRTSIII slab-type ballastless track slab. Background technique [0002] In the existing slab-type ballastless track slab, after the fastening device and the formwork are installed, it is usually necessary to pour self-compacting concrete into the track slab. The existing self-compacting concrete pouring method is to reserve a pouring hole in the middle of the top surface of the track slab. And use the storage hopper, small hopper, frame and other devices to grout from top to bottom through the pouring hole. The volume of the storage hopper meets the pouring amount of a track plate. The small hopper is used to observe the flow of self-compacting concrete during pouring. The frame The function is to support the weight of storage hoppers and small hoppers for easy t...

Problems solved by technology

[0003] The disadvantages of the above method are: the preset pouring hole is located on the upper part of the track slab and the hole diameter is small, the flow rate of the self-compacting concrete is slow, the pouring speed is slow, and the inspection index of the self-compacting concrete is high, if the self-compacting concrete collapses If the slump of self-compacting concrete is too small, it is easy to cause segregation, and the foam layer will easily appear after pouring. If the slump of self-compacting concrete is too small, it will not be easy to fill
