Abstract
The utility model, the deformation modulus E <v2> measuring instrument, belongs to the testing equipment field, which comprises the four parts of a loading device, a load carrying device, an electronic determination device and a settlement measuring device. The force-applying loading device includes a jack, to which the load carrying device, including a load carrying plate, connects in order to receive the acting force. The force sensor under the jack is connected to the electronic determination device, while the load carrying plate is connected to the measuring bridge and measuring indicator of the settlement measuring device. The utility model adopts the secondary loading method, which can be thought to have eliminated the plastic deformation of the clay filler in subgrade engineering and can really reflect the real strength of the subgrade filling. Making use of the level principle, the utility model figures out the settlement volume of the load carrying plate center through reading the measuring indicator on the measuring bridge support that is equipped on the back part of the level-type measuring arm, which makes the measuring indicator be far away from the counter-force device and can greatly reduce the labor strength of the test personnel. The electronic measuring device being adopted has such advantages as of small volume, quick dynamic response, high measuring accuracy and simple operation and so on.
