GRC Causes and solutions of line leakage
Baotou GRC The causes of water leakage are as follows:
1) Polymer mortar plastering layer and waterproof coating layer on GRC line surface are not constructed according to the construction design drawings; After the 29-12 experiment in Jinyuan Community, the external wall insulation was removed, and the main cause of water leakage was determined through the irrigation test, and the GRC line leakage was analyzed.
2) There is no slope at the top of GRC line, the drainage is not smooth, there is a gap between GRC line and ceramsite concrete, and the plastering layer on ceramsite concrete is seriously damaged.
3) GRC line is filled with ceramsite concrete, and the external wall is made of benzene plate, all of which are hydrophobic materials. The water entering the insulation cannot be evaporated or discharged as soon as possible, causing water to enter the wall.
4) GRC line is damaged after several freeze-thaw cycles.
The treatment scheme is as follows:
1) The construction shall be carried out according to the original design drawings, and the top surface of GRC line shall be plastered with polymer mortar and applied with waterproof paint.
2) Remove GRC lines, paste benzene plates, and then carry out grid cloth construction, putty layer construction and coating layer construction.
3) GRC line grid cloth packaging construction, putty layer construction, coating construction; Setting of door scaffold: the basic structure is composed of door frame, cross support, connecting rod, scaffold board or horizontal frame, lock arm, and horizontal reinforcing rod, scissors support, sweeping rod, sealing rod, support and base are set. The standardized steel pipe scaffold connecting the wall parts and the main structure of the building is used. Door frame, cross support, scaffold board, connecting rod, lock arm, horizontal frame, horizontal reinforcement rod, scissors support, bottom sweeping rod, sealing rod, base, connecting wall, railing, handrail. Considering the actual situation on site, the third scheme is selected.
