Title (EN) DITCHING METHOD AND DEVICE
(FR) PROCEDE ET DISPOSITIF DE CREUSEMENT DE SAIGNEES
Abstract: front page image
(EN)For the ditching of drains normally various types of excavating machines are used. This involves problems, however, especially when the ground has poor carrying capacity, for example in wet lands. According to the invention, therefore, a body (1) is proposed which has substantially V-shaped cross-section and smooth lower sides, and which is advanced through the soil masses to be removed for ditching the drain with a pointed and along the height of the body closed end facing in the direction of advancement, and which simultaneously is subjected to at least downwardly directed striking forces with relatively high frequency, whereby the body (1) is maintained pressed down into the soil masses while it is being advanced. The soil masses are thereby removed substantially in lateral direction by the side surfaces (2) of the body and compacted. For effecting the striking forces, preferably a vibrator (11) is provided within the body (1).
(FR)Divers types de machines d"excavation sont utilises pour creuser des saignees d"ecoulement. Cependant, celles-ci presentent des problemes notamment lorsque le sol possede de mauvaises caracteristiques portantes, par exemple dans les terres mouillees. Selon le present dispositif, un corps (1) possede une section sensiblement en forme de V et des cotes inferieurs lisses, qui avancent au travers de la masse de terre a enlever pour creuser la saignee d"ecoulement avec une pointe et le long de la hauteur de la face extreme fermee du corps dans le sens de progression, et il est soumis au moins a des forces de frappe dirigees vers le bas avec une frequence relativement elevee, de telle sorte que le corps (1) est maintenu appuye vers le bas dans la terre au fur et a mesure qu"il avance. Les masses de terre sont ainsi enlevees sensiblement dans le sens lateral par les surfaces laterales (2) du corps et compactees. Pour effectuer les forces de frappe, il est prevu un vibrateur (11) dans le corps (1).
