4. After each day of construction, the analysis processing submodule 63 acquires the value of the displacement sensor 61 through the data acquisition submodule 7, and compares the value of the displacement sensor 61 with the prescribed value of the prescribed value setting submodule 62.

5. When the value of the data acquisition submodule 7 is greater than the value of the specified value setting submodule 62, the analysis processing submodule 63 generates a displacement check quantity according to the difference between the values of the data acquisition submodule 7 and the specified value setting submodule 62, divides the check quantity into a plurality of equal check quantities, inputs the check quantities to the oil pump module 5 so that the jack 2 horizontally moves the abutment 12 for one time, the data acquisition submodule 7 acquires the measured value of the displacement sensor 61, and when the value of the displacement sensor 61 is greater than the value of the specified value setting submodule 62, repeats the step S2 until the value of the displacement sensor 61 is less than the value of the specified value setting submodule 62.
