Title:
BACKFILLING METHOD
Document Type and Number:
Japanese Patent JP3545641
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To backfill a groove formed by various works so as to have desired strength by inputting at least an aggregate and wet improved earth in the groove of a backfilling object, and backfilling thereafter the inside of the groove by mixing at least the aggregate and the wet improved earth.
SOLUTION: When inputting wet improved earth 3 in a groove 1, an aggregate 2 and the wet improved earth 3 are mixed by an agitating means 4 such as a backhoe. A backfilling material by mixing the aggregate 2 and the wet improved earth 3 is uniformly leveled in the groove 1. According to such a technique, since the aggregate 2 is mixed with the wet improved earth 3, strength can be improved more than when independently using the wet improved earth 3. Since the wet improved earth 3 is used, there is no need to roll the backfilling material 5, so that a required process is only to fill the backfilling material 5 in the groove 1. Thus, the groove formed by various works can be inexpensively backfilled so as to have desired strength.
