Title
(EN) GROUTING APPARATUS FOR HIGHLY COAGULATIVE GROUTING MATERIAL
(FR) APPAREIL D'INJECTION DE COULIS POUR MATÉRIAU D'INJECTION DE COULIS HAUTEMENT COAGULABLE
(ZH) 用于高凝结性注浆材料的注浆装置
Abstract
(EN) The present invention relates to the field of grouting, and in particular to a grouting apparatus for a highly coagulative grouting material. The grouting apparatus comprises a grouting pipe, a connector and a self-sealing pipe head. One end of the connector is connected to a grouting pump through the grouting pipe. The other end of the connector is connected to the self-sealing pipe head through the grouting pipe. The grouting pipe has fixed, sealed connections with the connector and the self-sealing pipe head. The grouting apparatus is easy to install. The grouting pipe is reliably connected to the connector and the self-sealing pipe head, and is reusable. The inner diameter of the connector matches the inner diameter of the grouting pipe, and the slurry outlet on an end cap of the self-sealing pipe head is circular, thereby effectively reducing pressure loss during a grouting process and having good grouting effects.
(FR) La présente invention concerne le domaine de l'injection de coulis et, en particulier, un appareil d'injection de coulis pour un matériau d'injection de coulis hautement coagulable. L'appareil d'injection de coulis comprend un tuyau d'injection de coulis, un raccord et une tête de tuyau auto-étanche. Une extrémité du raccord est reliée à une pompe d'injection de coulis par l'intermédiaire du tuyau d'injection de coulis. L'autre extrémité du raccord est reliée à la tête de tuyau auto-étanche par l'intermédiaire du tuyau d'injection de coulis. Le tuyau d'injection de coulis possède des raccordements fixes et étanches au raccord et à la tête de tuyau auto-étanche. L'appareil d'injection de coulis est facile à installer. Le tuyau d'injection de coulis est relié de manière fiable au raccord et à la tête de tuyau auto-étanche, et est réutilisable. Le diamètre interne du raccord correspond au diamètre interne du tuyau d'injection de coulis, et la sortie de boue sur un obturateur d'extrémité de la tête de tuyau auto-étanche est circulaire, ce qui permet de réduire efficacement la perte de pression pendant un processus d'injection de coulis et d'obtenir de bons effets d'injection de coulis.
(ZH) 本发明涉及注浆领域,特别是一种用于高凝结性注浆材料的注浆装置。包括注浆管、连接头和自封式管头,连接头的一端通过注浆管与注浆泵连接,连接头的另一端通过注浆管与自封式管头连接,注浆管与连接头、自封式管头之间均为固定密封连接。其安装方便,注浆管与连接头、自封式管头连接可靠,能够重复使用;由于连接头的内径与注浆管内径保持一致且自封管头端帽上的出浆口为圆形出浆口,有效地减少了注浆过程中的压力损失,注浆效果好。
