The invention discloses a protection device and a protection method for a pre-embedded sleeve of steel bars. The device comprises: a protective cover for being sleeved on the pre-embedded sleeve. The protective cover is hollow and has openings at both ends. The protective cover The first end of the cover is formed with a first socket matching the embedded sleeve, and the second end of the protective cover is formed with a second socket with a diameter larger than the diameter of the steel bar; A blocking member, when the flexible blocking member blocks the second socket, a reserved section exposed outside the protective cover is formed. The invention solves the problems of insufficient protection of the existing pre-embedded sleeves, difficulties in post-processing, inability to guarantee the connection quality of steel bars and affecting structural safety, and the like.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a protection device and a protection method for a steel bar pre-embedded sleeve. Background technique [0002] With the rapid development of subway construction, the functions that subway stations need to realize are also gradually increasing. Not only in the operation process, but also in the construction process, the reserved openings involved in the construction process are also gradually increasing. Including reserved hoisting holes, reserved auxiliary connection ports and other openings for different purposes. After the function of the reserved hole is realized, the pre-buried hole will be connected and constructed. At this time, it is necessary to dig out the embedded sleeve at the reserved hole and connect the connecting steel bar to the embedded sleeve. The connection strength of the steel bars at the joint determines the safety and service life of the rese...
