PURPOSE: To use a settlement meter for a long period of time without being subject to the effect of the nature of the soil of the ground, etc., and enhance the fixing force of an anchor to the ground, etc.
CONSTITUTION: In a settlement meter 1, in which an anchor A is inserted into a pit B drilled to the ground, the anchor A is fixed into the pit B and the quantity of the ground displaced is measured by the displacement of a displacement-quantity detecting rod 12 inserted into the pit B from the anchor A and extended on a ground surface, the anchor A has a base body 2, to which the displacement-quantity detecting rod 12 is connected, and a baggy fixing member 3 consisting of a woven fabric wrapping the whole circumference of the base body 2 with specified looseness in order to form a space C capable of being filled with mortar M between the fixing member 3 and the base body 2. The space C is filled with mortar M through a connecting pipe 10 inserted into the pit B from the ground surface and communicated and connected to the space C. Accordingly, the looseness sections 7 of the fixing member 3 are expanded, thus fastening the anchor A into the pit B.
