La présente invention se rapporte à un dispositif et à un procédé de mise sous pression de lances à eau ainsi qu'à un matériel de lutte contre le feu. Le dispositif de mise sous pression de lances à eau comprend un tuyau d'acheminement de jet d'eau formé de multiples lances à eau (1) qui sont en communication les unes avec les autres. Une pompe électrique à écoulement axial (2) est disposée au niveau d'un nœud entre deux lances à eau adjacentes (1). Le centre axial des pales de la pompe électrique à écoulement axial (2) est parallèle à une direction d'écoulement d'eau dans la lance à eau (1) et la pompe électrique à écoulement axial (2) est utilisée pour mettre sous pression, le long de la direction d'écoulement d'eau, l'eau qui circule à travers le nœud. Le dispositif de mise sous pression de lances à eau met sous pression l'eau par relais après que l'eau passe dans l'ordre à travers les nœuds, ce qui permet de résoudre le problème selon lequel il est difficile de transporter l'eau jusqu'au sommet d'un bâtiment pour combattre le feu. La présente invention présente les avantages suivants : l'efficacité de la lutte contre le feu est élevée, l'opération est flexible et la structure est compacte.
