The invention relates to a plastic plate for lining concrete components through which a fluid medium flows. Said plastic plate is provided with a plurality of anchor elements (10) which are mounted on the side (1B) thereof oriented towards the concrete component wall and which make it possible to positively fixe said plastic plate to the concrete component. The side (1A) of the plastic plate oriented to a medium is provided with a plurality of adjacent flow elements (4) which are embodied in the form of elevated structures comprising an upstream flank (4A) oriented in a flow direction (9) and an oppositely oriented downstream flank (4B), wherein the superficial areas located between the flow elements are smoothly shaped. In such a manner, it makes it possible to increase a dragging effect of medium-carried particles in order to avoid solid deposits even at a low flowrate. In the preferred embodiment, the flow elements are constructed in the form of narrow webs which have a wedge-shaped cross section and are distributed in individual rows (IV) side by side transversally to the longitudinal axis (5) of the plastic plate. |
