Description

Concrete track slab pouring slurry blocking strip Technical Field The utility model relates to the field of manufacturing of auxiliary equipment of a railway working section, in particular to a slurry blocking strip used when a steel mould is used for pouring a track slab. Background At present, in the field of rail transit, rail slabs along the railway are mostly cast integrally by using steel dies. As generally shown in fig. 7 and 8. The inside concrete mortar that fills of steel mould M is pour, and steel reinforcement runs through gap S is offered to steel mould M side, and the steel reinforcement runs through from steel mould M inside and goes out, cooperates with the inside steel reinforcement cage of steel mould M and provides structural strength for the track slab after the shaping. Because the steel bar penetrating gap S is not just reserved with a steel bar M pipe perforation, but is a gap which is formed into a rectangle or a waist shape integrally, the grouting pouring needs to be blocked to prevent slurry leakage. At present, a temporary plugging is mostly adopted by adopting waste materials such as plugging steel sheets or wood sheets, and the problem of slurry leakage exists in a certain gap caused by loose tolerance or fit between the plugging sheets and gaps. By searching, technical literature disclosures on concrete pouring plugging devices exist in the prior art. For example, the utility model authorization bulletin document with publication number of CN201649638U entitled "sealing strip for casting leakage-proof slurry". The utility model discloses a sealing strip for pouring leakage-proof slurry in a template, which structurally comprises a strip-shaped platy main body, wherein strip-shaped bulges are arranged along the radial direction of the platy main body, and at least two bulges are arranged. When the sealing strip is used, the sealing strip is inserted between adjacent templates, the gap between the templates is reduced, the pressure between the adjacent templates is utilized to enable the sealing strip to completely block the gap between the templates, so that the sealing effect between the templates is realized, and the slurry leakage during concrete pouring is avoided. For example, the publication number of CN221000650U is named as an utility model authorization notice file of a combined grout stop strip which is used for directly splicing square pier columns with the existing template. The combined grout stop strip for the square pier stud and the existing template can be directly spliced and assembled, and comprises an air bag and an air bag bearing groove, wherein the air bag is matched with the air bag bearing groove, the air bag is fixedly communicated with an inflation tube, a group of evenly distributed threaded holes are formed in the air bag bearing groove, and the threaded holes are in threaded connection with bolts. And the air bags in the slurry stopping strip combination are utilized to expand to seal the gaps, so that the gaps are plugged. The plugging strip provided by the above reference does not consider the matching contact seal between the plugging strip and the steel bars, and cannot solve the problem of slurry leakage during pouring of the track slab. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a concrete track slab pouring slurry blocking strip, which comprises at least one blocking piece with a smooth surface and overall flexibility, wherein the blocking piece is provided with a via hole, the external dimension of the blocking piece is matched with the dimension of a steel bar penetrating gap of a steel die, and the via hole is matched with the outer diameter of the steel bar. Further, the periphery of the plugging sheet is provided with a first magnetic attraction edge. Further, there is a break between the edge of the via and the side of the plug. Further, the fracture part is a fracture groove formed in the surface of the plugging piece. Or the plugging sheet can be assembled and spliced by split sheets, half through holes are formed in the end parts of the split sheets, and the through holes are formed after the end parts of the split sheets are spliced. Further, the end part of the split piece is provided with a second magnetic attraction edge. Further, the side edge of the plugging piece is provided with a step, the height of the step is consistent with the thickness of the steel mould, and the first magnetic attraction edge is positioned on the inner side surface of the step. Further, the via hole comprises an upper via hole and a lower via hole, and the top of the plugging piece is semicircular. Compared with the prior art, the technical scheme has the advantages that the slurry blocking strip is integrally made of flexible materials, the side edge of the slurry blocking strip can be tightly contacted and sealed with a steel bar penetrating gap, a through hole of the slurry blocking strip can also
