Novel pore pressure gauge
The invention discloses a novel pore pressure gauge. The pore pressure gauge comprises a pore pressure gauge shell and a permeable part connected in the pore pressure gauge shell, a through hole channel is formed in the pore pressure gauge shell, and the diameter of the hole channel opening is smaller than the diameter in the hole channel. The permeable part is arranged in the hole channel, a semi-permeable membrane which is tightly attached to the outer wall of the permeable part and the inner wall of the hole channel is arranged between the permeable part and the hole channel opening, the section of the semi-permeable membrane is in a U shape, and at least three flocculation layers are coated in the semi-permeable membrane in a layered mode. By utilizing the coalescence property of the flocculating agent, the flocculation layers are added outside the permeable part, and fine particles in a soil layer or a water layer are gathered together for layer-by-layer filtration, so that clogging of the pore pressure gauge can be avoided, and measurement errors caused by clogging are reduced.
本发明公开了一种新型孔压计，包括孔压计外壳和连接在孔压计外壳内的透水部件，所述孔压计外壳内形成有贯穿的孔道、且所述孔道口的直径小于所述孔道内的直径，所述透水部件设于所述孔道内，所述透水部件与所述孔道口之间设有紧贴在透水部件外壁与孔道内壁上的半透膜，所述半透膜的截面呈U型状，所述半透膜内分层涂有至少三层絮凝层。本发明利用絮凝剂的“聚并”性质，在透水部件外添加絮凝层，将土层或水层中的细颗粒聚齐起来进行层层过滤，可避免孔压计发生淤堵，并减小由此所造成的测量误差。
