Embodiment Construction

[0021] A kind of embodiment 1 of soil interface shear testing machine is as Figure 1~3 Shown: It includes a soil layer interface shear test box and a loading device. The loading device includes a device frame. The device frame includes two sets of columns arranged at intervals on the left and right. . A vertical loading mechanism is arranged on the top beam, and the vertical loading mechanism includes two vertical loading cylinders 1 arranged at intervals on the left and right. The piston rods of the two vertical loading cylinders 1 are connected with an upper pressure plate 30, and the piston rods of the vertical loading cylinders A first force sensor 4 is arranged between the rod and the upper pressing plate. The column 9 on the right side is provided with a vertical guide rail 17 extending vertically along the guide direction, and a lateral loading mechanism is equipped with a guiding movement on the vertical guide rail 17. The setting can be moved up and down to adjust ...

Abstract

The invention relates to a soil layer interfacial shear testing machine and a soil layer interfacial shear testing box. The soil layer interfacial shear testing box comprises an upper box body and a lower box body, the lower box body is provided with an inner cavity communicating with the upper box body for filling a testing soil layer, or the lower box body is provided with a resistance plate used for making friction contact with the testing soil layer in the upper box body, the upper end of the upper box body is open, an upper pressing plate used for pressing the testing soil layer in the upper box body is arranged at the power output end of a vertical loading mechanism, a lower guiding structure with the transverse guiding direction is arranged between the lower box body and a device frame, an upper guiding structure with the transverse guiding direction is arranged between the upper box body and the lower box body, and the power output end of a transverse loading mechanism is in transmission connection with the lower box body. The soil layer interfacial shear testing machine capable of testing soil layer interfacial shearing force, and the soil layer interfacial shear testing box used in the soil layer interfacial shear testing machine are provided by the invention.

Description

technical field [0001] The invention relates to a soil layer interface shear test machine and a soil layer interface shear test box for testing the shear force of the soil layer. Background technique [0002] In the field of construction engineering, it is usually encountered in the case of engineering construction and treatment in the soil layer, such as slope and foundation pit engineering, pile foundation engineering, soil nailing support and subway tunnel engineering. The engineering practice in the soil layer, the shear force in the soil layer or between the soil layers, and the interface shear force test and cognition between the soil layer and soil nails, piles, tunnels and other structures are related to the whole The economical rationality, safety and stability of engineering design and construction. At present, there is a lack of a soil interface shear testing machine capable of testing the soil interface shear force. Contents of the invention [0003] The purp...
