To arrange a screen 7 in the ground, instead of screen parts being driven or vibrated in, a longitudinal trench 4 is dug in the ground, the walls of which trench can be supported by moving support plates 5 and in which trench guide pieces 6 for guiding solid screen parts which are to be introduced are arranged. The space in the trench next to the screen parts 7 can then be filled in, for example with material which was dug out when the trench was made. When using separate panels 7 to construct the screen, these panels may engage in one another along their adjacent edges by way of complementary parts, and can be joined together in a sealed manner by means of a setting adhesive. <IMAGE> |
