An automatic anti-additive pouring method of a semi-shield method is provided to pour anti-additives through a distribution panel, recording the quantity of pouring anti-additives with electronic and electric control method by a control box and keeping a record in document. An automatic anti-additive pouring method of a semi-shield method comprises the steps of: attaching many assembly pipes(3) in a drilling direction if a space is formed at the rear of a semi-shield(2) by the drilling work of a semi-shield attached with a rotary cutter(1); connecting a control box(10), a bentonite mixing pump(20) and an air compressor(30) with a distribution panel(11), a solenoid(21) and a butterfly valve(31); putting anti-additives in a tank of the bentonite mixing pump and operating the control box, the bentonite mixing pump and the air compressor; transmitting orders to the distribution panel through an electric control cable(12) by inputting work in the control box while the anti-additives poured from the bentonite mixing pump flows toward the butterfly valve coupled along a bentonite line pipe(22); operating the solenoid coupled to the distribution panel and opening the butterfly valve, and pouring anti-additives together with air supplied from the air compressor through an air line pipe(32); converting the pressure difference by space variation between the outside of the assembly pipe and the drilled ground into each record; and printing the record inputted with the quantity of pouring anti-additives using a printer coupled to the control box, and keeping a record in document.
