Roof engineering (GB50207-2002)
(1) basic indices such as strength, thickness, moisture content of the construction should comply with the national standard design requirements, can undertake PVC waterproofing construction.
(2) to determine the direction and sequence planning coil the shop is stuck, according to the outline of the waterproof layer of natural layout at the grassroots level. Flat straight, not curved, according to the specification requirements of lap lap width.
(3) according to the selection of fixed, fixed method such as mechanical fixation method, the full article stick method, viscosity method, etc.
(4) waterproofing lap welding parts, should be wiped clean, dry, with hot air welding, welding when the welding nozzle and 45 ° Angle to the direction of welding, pressure roller and the welding nozzle parallel and keep a distance of about 5 mm, welding edge should have a bright color magma effusion, should not be burnt.
(5) coil by layering fixed head, with sealing oil seal, cement mortar to seal.
(6) the whole project waterproof comprehensive quality checks, the processing parts are completed.
Underground engineering (GB50208-2002)
(1) basic indices such as strength, the thickness of the moisture content of the construction should comply with the national standard design requirements, can undertake PVC waterproofing construction.
(2) according to the different rational selection method of waterproof area specific executive GB50208-2002 standard.
(3) coil lap width should be 100 mm, the lower coil should be down the upper coil.
(4) lap seam appropriate USES multiple welding, the welding width of a single seam is not less than 100 mm.
(5) the laid of PVC waterproofing materials should be smooth and with the base fixed firmly, can not have prolapse, taut and damage phenomenon. Confirmed by the check behind the construction of next working procedure can be performed.
Application of tunnel engineering and special occasions
Application of tunnel engineering and special occasions with reference to the relevant national standard.
