THE WATERPROOF METHOD OF SHEET LINING USING BY AIR SUCTION DEVICE

摘要

A waterproof method of sheet lining is provided to confirm the adhesion of the whole waterproof sheet attached to a structure at a time using an air suction device, thereby securing reliability of sheet joint and reducing the inspection cost. A waterproof method of sheet lining comprises an air suction device(30), an air exhaust port(32), an exhaust pipe(31), a valve(33), a manometer(34), and an adhesive inlet port(35). The air suction device discharges the air between a waterproof sheet(20) and a structure(10) to the atmosphere. The air exhaust port is installed through the waterproof sheet. The exhaust pipe connects the air suction device and the air exhaust port to move the air. The valve is installed in the exhaust pipe in order to block the air flow of the exhaust pipe. The manometer is installed in the exhaust pipe in order to measure the air pressure variation of the space between the waterproof sheet and the structure. The adhesive inlet port injects an adhesive into between the structure and the waterproof sheet using the suction force of the air suction device.
