Pre-grouting type full-grouting sleeve structure and construction method
The invention discloses a pre-grouting type full-grouting sleeve structure which comprises a sleeve, two connecting steel bars are arranged in the sleeve, locking bolts are arranged on the connecting steel bars, a grouting nozzle and a grout outlet pipe which are communicated with the interior of the sleeve are installed on the sleeve, lantern rings are in threaded connection with the connecting steel bars, and the lantern rings are in threaded connection with the connecting steel bars. A stirring plate is fixedly connected to the lower end of the lantern ring, an annular groove is formed in the lantern ring, and an annular plate is connected into the annular groove in a sealed and sliding mode. The invention further provides a construction method of the pre-grouting type full-grouting sleeve structure. The construction method comprises the following construction steps that S1, the prefabricated parts are manufactured; s2, grouting is conducted; and S3, cutting off the redundant part of the grouting nozzle and the grout outlet pipe. The pushing device pushes the lantern ring to rotate back and forth, on one hand, injected concrete slurry is evenly stirred, concrete is evenly connected with all positions of the connecting steel bars, on the other hand, an early strength agent can be continuously extruded out to be mixed with the concrete, the setting time is shortened, and the construction efficiency is improved.
本发明公开了一种预灌浆式全灌浆套筒结构，包括套筒，所述套筒内设有两个连接钢筋，且所述连接钢筋上设有锁紧螺栓，所述套筒上安装有与其内部相通的注浆嘴与出浆管，所述连接钢筋上螺纹连接有套环，所述套环下端固定连接有搅动板，所述套环上的开设有环形槽，所述环形槽内密封滑动连接有环形板。本发明还提出了一种预灌浆式全灌浆套筒结构的施工方法，包括以下施工步骤：S1、制作预制构件；S2、灌浆；S3、切除多余部分的注浆嘴与出浆管部分。本发明通过推动装置推动套环来回转动，一方面将注入的混凝土泥浆搅拌均匀，使混凝土与连接钢筋各处均匀连接，另一方面，还可不断将早强剂挤出与混凝土混合，缩短凝固时间，提高施工效率。
