Fine tuning claw U-shaped isolating protective buckle special for grouting of high-speed railway II-type slab

The invention discloses a fine tuning claw U-shaped isolating protective buckle special for the grouting of a high-speed railway II-type slab. The fine adjustment claw U-shaped isolating protective buckle is used for isolating and sealing mortar (8) at a fine adjustment claw (5) during grouting and is characterized by mainly comprising a transverse sealing baffle plate (1), a first longitudinal sealing baffle plate (2) and a second longitudinal sealing baffle plate (3), wherein the first longitudinal sealing baffle plate (2) and the second longitudinal sealing baffle plate (3) are respectively arranged at the left end and the right end of the transverse sealing baffle plate (1). The invention has convenient use, low cost and time and labor saving, overcomes the defect that the mortar is leaked at the fine adjustment claw during sealing edge, realizes effective isolation on the fine adjustment claws while effectively sealing cushion layer mortar and ensuring high filling degree of the cushion layer mortar, and
