Abstract: Provided are a reinforcing method and a reinforcing structure for a manhole having a neck part in a position shifted from the middle part of an upper slab which allow the buried manhole to be reinforced sufficiently against stress inflicted thereon while reducing the operation and material costs involved in the reinforcement.

Abstract: A calculation apparatus includes a first acquisition unit that acquires a first approximation expression based on a change in a temperature of a temperature controlled member with respect to a change in an outside temperature measured for a plurality of temperatures of a temperature controlling member, a second acquisition unit that obtains a second approximation expression based on the first approximation expression, a temperature input unit that receives input of a first set temperature of the temperature controlled member and a second set temperature of the temperature controlling member, a generation unit that substitutes the second set temperature into the second approximation expression to generate a third approximation expression representing relationship between the outside temperature and the temperature of the temperature controlled member, and a calculation/output unit that substitutes the first set temperature into the third approximation expression to calculate an outside temperature to be set.

Abstract: Provided are a reinforcing member and a construction method capable of easily securing a side wall contact height even in the case where installed equipment is provided on a side wall. A reinforcing member according to the present invention is a reinforcing member which reinforces a manhole by being fixed to the manhole in a state in which at least part of the reinforcing member is in contact with a side wall inner surface of an inner surface of the manhole, an insertion hole into which an anchor bolt provided to protrude from the inner surface of the manhole can be inserted is formed, and the insertion hole is an elongated hole which allows the reinforcing member to move relative to the anchor bolt in an inserted state in which the anchor bolt is inserted into the insertion hole and an unfixed state in which the reinforcing member is not fixed to the manhole.
