Title (EN) DEVICE AND METHOD FOR HORIZONTAL ROTARY JETTING CONSTRUCTION
(FR) DISPOSITIF ET PROCÉDÉ DE CONSTRUCTION PAR INJECTION ROTATIVE HORIZONTALE
(ZH) 一种水平旋喷施工装置及施工方法
Abstract: front page image
(EN)A construction device and a construction method for automatically balancing surrounding soil body pressure during a horizontal rotary jetting reinforcement construction are provided. The device comprises a nozzle (1), a grouting pipe (2), a hole port sealing device fixed to a working well wall, a valve (3) adjusting opening pressure automatically, and a pressure detection device (4). The pressure detection device (4) is not mounted at the nozzle (1) or the grouting pipe (2), but mounted at the sealing device. The valve (3) will be opened automatically, when the slurry pressure is greater than the preestablished opening pressure of the value (3). Therefore, utilizing the device and the method, the balance between the slurry pressure and the surrounding soil body pressure was kept all the time during a horizontal rotary jetting reinforcement construction.
(FR)La présente invention est relative à un dispositif et un procédé de construction permettant d'équilibrer automatiquement la compression du sol lors d'une consolidation par injection rotative horizontale. Ledit dispositif est composé d'une buse (1), d'un tuyau d'injection (2), d'un dispositif d'étanchéité fixé sur la paroi du puits de travail, d'une valve (3) régulant automatiquement la pression d'ouverture ainsi que d'un dispositif (4) de détection de pression installé non pas sur la buse (1) ou le tuyau d'injection (2) mais sur le dispositif d'étanchéité. Dans le cas où la pression du mortier dépasse la pression d'ouverture prédéfinie, la valve (3) s'ouvre automatiquement. L'utilisation des présents dispositif et procédé de construction permet d'équilibrer en permanence la pression du mortier et celle du sol lors d'une consolidation par injection rotative horizontale.
