Title
(EN) METHOD OF DISINTEGRATING AND MIXING SOIL AND APPARATUS THEREFOR
(FR) PROCEDE DE DESINTEGRATION ET DE MELANGE DU SOL ET DISPOSITIF CONÇU A CET EFFET
Abstract
(EN)
The present invention relates to a method of disintegrating and mixing soil, and an apparatus therefor, by which soil in soft ground and a soil improving agent can be efficiently disintegrated and mixed with each other to provide an improved soil. In the method, when mixed by a disintegrator (7), soil and a soil improving agent conveyed are mixed with each other while cut and disintegrated in a primary cutting, disintegrating and mixing, and the soil and the soil improving agent after the primary cutting, disintegrating and mixing are mixed with each other while strikingly disintegrated in a secondary cutting, disintegrating and mixing. The apparatus comprises a disintegrator (7) having a rotary cutter (13) provided on an upper side thereof and a rotary striker (10B) provided on a lower side thereof in an interior thereof, and a conveyor (8) provided on a vehicle body (3) for conveying soil and a soil improving agent into the disintegrator (7).

Procédé de désintégration et de mélange du sol et dispositif conçu à cet effet, grâce auquel le sol d'un terrain meuble et un agent d'amendement du sol peuvent être efficacement désintégrés et mélangés l'un à l'autre pour produire un sol amélioré. Selon ce procédé, un désintégrateur (7) assure le mélange du sol et de l'agent d'amendement du sol acheminés pendant qu'ils sont désintégrés et découpés dans une première opération de découpe, de désintégration et de mélange. Après cette première opération, le sol et l'agent d'amendement du sol subissent une deuxième opération de mélange alors qu'ils sont concassés et mélangés. Le dispositif comprend un désintégrateur (7) pourvu d'un organe de découpe rotatif (13) logé dans sa partie supérieure et un concasseur rotatif (10B) logé dans la partie inférieure latérale de ce dispositif; ainsi qu'un convoyeur à bande (8) monté sur le châssis du véhicule (3) pour acheminer le sol et l'agent d'amendement du sol vers le désintégrateur (7).
