Description

Valve sleeve assembly protection device Technical Field The utility model relates to the technical field of sleeve valve pipe protection, in particular to a sleeve valve pipe assembly protection device. Background The sleeve valve pipe is also called as a flower pipe, and is a construction method in building construction, the steel sleeve valve pipe with holes is driven into or drilled into soil, then the slurry is injected into the flower pipe by pressure, the slurry is injected into the soil layer from the holes, then the flower pipe is lifted or sunk and continuously injected, reinforced soil is formed in the soil, and the foundation strength is improved. In the prior art, the protection device of the sleeve valve pipe assembly with the bulletin number of CN204551479U is characterized in that a protection ring is arranged on the outer wall of the sleeve valve pipe assembly, and the sleeve valve pipe assembly is arranged downwards, so that the rubber hoop can be prevented from being scratched, the guide can be assisted, and the sleeve valve pipe assembly is ensured to be vertically arranged downwards. However, the following drawbacks exist in the above technical solutions and the prior art: Firstly, the rubber band in the device is only wrapped on the annular side surface of the sleeve valve pipe assembly, and the corresponding limiting structure is not used for blocking and limiting the rubber band, so that the rubber band is easy to deviate up and down in the use process, the slurry outlet hole cannot be well plugged once the rubber band deviates up and down, and the protection ring in the device can prevent the rubber band from being scratched to protect the rubber band, but the sleeve valve pipe assembly is continuously rubbed with the ground in the process of drilling and inserting the rubber band into the ground, the outer surface of the protection ring is not provided with the corresponding wear-resisting structure, so that the protection ring is easy to wear in the use process, the outer diameter of the worn protection ring is reduced and cannot protect the rubber band, and a user needs to replace the worn sleeve valve pipe assembly integrally frequently, so that the practicability is poor.
