For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of saturation device of hollow cylinder clay sample, comprise metal outer mold, the outside wall surface of described metal outer mold internal face and hollow cylinder clay sample is suitable, also comprise anchor clamps, behind the filling gas with the suitable air bag of hollow cylinder clay sample internal face, separation layer, described anchor clamps comprise two clamping plate, pull bar and the nut that is connected with pull rod screw, described metal outer mold places between two clamping plate, and metal outer mold and be positioned at metal outer mold up and down two clamping plate at two ends link into an integrated entity by pull bar and nut, in addition, order is provided with filtering layer and pervious bed between described hollow cylinder clay sample and the clamping plate; Between described metal outer mold and the hollow cylinder clay sample separation layer is set; Described air bag is provided with pore.
The xsect of described metal outer mold is circular, and this metal outer mold split is provided with the seam crossing installation Rubber water stop bar of adjacent two splits; Each split of metal outer mold is by being socketed in the shroud ring banding of metal outer mold outside wall surface simultaneously.
Described separation layer adopts inviscid plastic sheeting to make.
Described metal outer mold is provided with the mouth of bleeding.
Sink into the setting of air bag internal cavities in the pore of described air bag.
According to above technical scheme, can realize following beneficial effect:
The present invention is provided with air bag in the inside of hollow cylinder clay sample, so that this hollow cylinder clay sample is provided support, prevents that caving in of clay sample from caving in by airbag aeration effectively; The present invention is provided with separation layer between this hollow cylinder clay sample and metal outer mold, prevent metal outer mold and clay sample adhesion effectively, destroys clay sample when avoiding form removal; The present invention is provided with the mouth of being made up of aspirating hole and rubber mouth of bleeding on metal outer mold, can guarantee that by bleeding plastic sheeting and metal outer mold are adjacent to, and effectively avoids the wrinkling breakage of plastic sheeting to influence its effect; Because plastic sheeting is inviscid, make metal outer mold and clay sample very easily peel off when tearing sample open, can not cause when tearing sample open disturbance to damage sample.Therefore, the utility model is simple in structure, is easy to realize, easy and simple to handle, with low cost, can prevent effectively that the hollow cylinder clay sample from caving in when saturated and the adhesion between sample and sample preparation mould when sample preparation and form removal, be a kind of hollow cylinder clay sample saturation device of highly effective.
