Underwater grouting equipment for large-volume cavity
The invention discloses underwater grouting equipment for a large-volume cavity. The device comprises a grouting pipe, the grouting pipe is connected with a non-return shell, the non-return shell is connected with a connecting ring, and the connecting ring is connected with a spray head; a supporting pin is fixedly arranged in the non-return shell, the outer portion of the supporting pin is hinged to the head end of a partition plate through a torsional spring, and the tail end of the partition plate is movably connected with the inner wall of the non-return shell. The two partition plates are arranged to be used in cooperation with the torsional spring, the two partition plates are folded during grouting so as to be separated from the non-return shell, slurry can be poured smoothly, when slurry flows back, the partition plates make contact with the non-return shell to seal the non-return shell, and therefore the slurry is prevented from flowing back, and the grouting efficiency is improved. Therefore, the effects of preventing the slurry from flowing back and improving the pouring quality are achieved.
本发明公开了一种用于大体积空腔的水下灌浆设备。本发明包括灌浆管，灌浆管连接止回壳体，止回壳体与连接环连接，连接环连接喷头；所述止回壳体内部固定设置有支撑销，支撑销的外部通过扭簧铰接隔挡板的头端，隔挡板的尾端与止回壳体的内壁活动连接。本发明通过设置两个隔挡板与扭簧配合使用，使得在灌浆时两个隔挡板合拢从而与止回壳体分离，使得浆料得以顺利的灌注，而在出现浆料回流时，隔挡板与止回壳体接触将止回壳体封闭，从而防止了浆料的回流，如此便达到了可防浆料回流提高灌注质量的效果。
