The technical scheme that this practical new its technical matters of solution is adopted is following:
A kind of soil body suction quality control apparatus comprises test stand, hanging basket, electronic weighting equipment and tank, and the top of said hanging basket hangs on the said test stand through electronic weighting equipment, and said tank is located at said hanging basket below; The permeable stone of the upper and lower surfaces that said hanging basket inside also is placed with the geotextile that is used to wrap up sample, be positioned over sample and the perforated plastic mould that is used to place parcel back sample.
As to the improving and replenishing of technique scheme, the utility model is further taked the following technical measures or the combination in any of these technical measures:
Preferable, said perforated plastic mould is cylindrical, and its sidewall is provided with perforation.
Preferable, said perforated plastic mould is made up of two semicircle cylindrical shells.
Preferable, the top of the permeable stone of the said upper surface that is positioned over sample also is provided with and adds loading.
