Abstract

The utility model discloses a device for directly measuring concrete lateral pressure. The device comprises a pipe template, flange plates I, bolts I, apertures, insulation wires, soil pressure sensors and a strain gauge. Self-compacting concrete is casted in the pipe template which is formed by stacking a plurality of pipe template segments vertically. The adjacent pipe template segments are in sealing connection via the flange plates I and the bolts I. The inner wall of the pipe template is provided with soil pressure sensors which are connected with insulation wires respectively. The insulation wires penetrate through the apertures in the wall of the pipe template and are led out of the pipe so as to be connected with the strain gauge. With the device in the utility model, requirements for direct measuring and studying self-compacting concrete template lateral pressure in a laboratory are met; besides, the device has the advantages that the device is concrete-unattachable; the device itself is light in weight; the device does not absorb water; the device can be used for many times; the device is low in cost and the like.
