A waterproof board detector comprises a strip-shaped base, a first sealing end and a second sealing end, and an air tightness detection device connected with the second sealing end, the first sealingend comprises a pressure block and a longitudinal buckling end used for adjusting the pressure block to move up and down; the second sealing end comprises a base table, a pressing block assembly for pressing the waterproof board, a transverse clamping buckle end, and two side pressing blocks located on the two sides of the base table respectively, and a protruding clamping part is arranged on theedge of the pressing block assembly, the clamping part is located between the side pressing blocks and the base table and is in sealing connection with the side pressing blocks and the base table, thepressing block assembly successively comprises a sealing part used for pressing the waterproof joint, a pressure detection part communicated with the air tightness detection device in the middle, anda fixing part connected with the transverse clamping buckle end from the inside to the outside, the bottom of the pressure detection part is provided with a T-shaped three-way guide pipe, the T-shaped three-way guide pipe is respectively connected with the air tightness detection device, the waterproof joint and the fixing part.
Description
technical field [0001] The invention relates to a waterproof board seam detection tool, in particular to a waterproof board tester. Background technique [0002] Waterproof panels are widely used in tunnel engineering and other low-level projects, and play a major role in structural waterproofing. The "Quality Acceptance Standards for Railway Tunnel Engineering Construction" published in 2004 pointed out that double-weld automatic heat-sealing technology is commonly used in China for the joints of waterproof boards. The inflation inspection method is to connect the injection town with the pressure gauge and inflate it with an air pump. When the pressure gauge reaches 0.25MPA, stop the inflation and keep it for 15min. If the pressure drops within 10%, it means that the weld is qualified. If the pressure drops too fast, it means there is leakage. Use soapy water to slaughter the weld, and re-weld where there are air bubbles until there is no air leakage. However, only the de...
