Abstract

PURPOSE: To prevent boiling, heaving, etc. in the sheathing of a weak ground, by filtering sand particles and mud from a bottom of a groove to pass the filtrated water upward.
CONSTITUTION: In the week ground, the earth is excavated to make a groove for control purpose, while on both sides thereof sheathing walls are constructed. A slope plate 3 is arranged longitudially in the excavated groove while on an upper surface of said slope plate 3 is placed a filter bed A containing therein a filter sheet 6, fine pebbles 8 and a net 7, and the slope plate 3 is gradually withdrawn to form the filter bed A on a groove bottom 9. Accordingly, from the groove bottom 9 only water can pass upward, so that spouting of sand particles or mud from the groove bottom 9 or heaving of the groove bottom 9 is prevented.
