Problems solved by technology

However, railway projects inevitably pass through a large number of soft soil areas, so the treatment and prevention of soft soil foundations have become a key link that affects project quality and investment benefits. Although the existing railway soft soil foundations have added reinforcement, testing and Repair the integrated pre-embedded body, but the soft soil foundation is generally deep, and it is difficult for the relevant inspectors to know the approximate location of the subsidence and collapse in the soft soil foundation through the existing pre-embedded bodies, and it cannot be accurately grouted for reinforcement. In addition, grouting Additional grouting auxiliary parts are required, which is very cumbersome and easy to damage the original upper foundation

Abstract

The invention discloses a pre-embedded body for railway track disaster repair detection and a method for using the same, and belongs to the field of railway track detection. A pre-embedded body for railway track disaster repair detection includes a pre-embedded steel pipe, and the outer end of the pre-embedded steel pipe is from top to bottom A plurality of slip rings are set in turn, and the outer end of the slip ring is fixedly connected with a plurality of extruded rods. The combination of the multiple slip rings and the extruded rods with the sliding opening and closing mechanism allows relevant inspectors to directly observe the pre-embedded The body knows the approximate location of the subsidence in the soft soil foundation, so that it can be grouted in time for reinforcement. In addition, the embedded body itself can be used for direct grouting. The construction personnel use the grouting equipment from the top of the embedded steel pipe to the embedded steel pipe. Grouting is enough, the slurry is directly sprayed from the downward sliding hole without sealing baffle, and injected into the subsidence area to realize automatic positioning and positioning grouting. The grouting efficiency is high, and no additional grouting auxiliary parts are needed to avoid Destroy the original upper foundation.

Description

technical field [0001] The invention relates to the field of railway track detection, and more particularly, to a railway track disaster recovery detection embedded body and a method for using the same. Background technique [0002] Rail transport is a form of land transport in which a locomotive pulls a train on two parallel rails. The traditional way is steel wheel travel, but railway transportation in a broad sense still includes non-steel wheel travel methods such as maglev trains, cable cars, cableways, or rail transportation. Rails provide an extremely smooth and stiff medium on which train wheels roll with minimal friction, making the occupants more comfortable and saving energy. Railway track, referred to as rail, rail, track, etc. Used on railways and cooperates with point switches to allow trains to walk without turning. The track usually consists of two parallel steel rails. The rails are fixed on the sleepers, and the ballast is under the sleepers. Rails mad...
