屋面防水施工的方案(国外英文资料) Waterproofing works Shi work square case Anhui first construction engineering company February 10, 2012 Construction project of modified asphalt waterproof roll roofing project I. General Situation of the project: \ The roof structure layer is cast-in-place reinforced concrete slab, the roof slope is 2%, the upper berth is 40mm thick, extruded polystyrene board insulation layer, and 20mm thick 1:3 cement mortar leveling layer. The roof waterproof is made of 3mm thick polymer modified asphalt waterproof roll. Two 、 quality work objective: (1) specific quality objectives; After the completion of the roof works without leakage, to meet the eligibility criteria. (two) the quality control standard of roof waterproof engineering; 1. the leveling layer requires a slit (6m * 6m), with no surface cracking, sand lifting and peeling. Flatness deviation is not greater than 5mm; 2., the roof slope of 2%, no inverted slope or water; 3., modified asphalt waterproofing membrane lap width is correct, with joints tight, node processing meets the specifications, no Alice, mouth; 4. waterproof layer on the protective layer of clinker integrity and no damage. (three) process quality inspection; 1. leveling layer roughness 2m ruler and check the surface layer and the largest gap between the ruler should not be more than 5mm, check the appearance of crack free, crisp, sand; 2. the slope is checked by a level or a horizontal ruler; Check the moisture content of 3. leveling, the spread of 1m2 modified asphalt waterproof coiled material shop in the leveling layer, the static 3~4h opened after the check the leveling layer covering part and modified asphalt waterproofing materials not watermark can be the laying of waterproofing layer; 4. joints should meet the requirements, strict sealing shall be slotted, Alice, Shuila mouth and outstanding facilities and roof roof junctions, should be firmly fixed, tight seal; 5. waterproof layer every completion of a process, should be c
