Road, bridge, culvert, sink joint, leak stoppage, tunnel deformation joint, leak stoppage Construction joint Waterproof maintenance
The waterproof maintenance of the construction joint of the construction joint of the road bridge culvert countersink and leak stoppage tunnel, Jiangsu Lanlong Building Waterproof and Leak stoppage Engineering Co., Ltd., and the waterproof maintenance of the construction joint of the deformation joint and leak stoppage tunnel of the road bridge culvert countersink and leak stoppage tunnel will be more reasonable if the abutment back is not backfilled to the top of the culvert. stay wall The construction joint between the cover plate and the construction joint shall be filled with foam board, dug to a depth of 20cm asphalt Filled with hemp. Later, lay a layer of felt on it with asphalt, and remember to stick it tightly, otherwise it will still leak. If the wall body is not backfilled at the abutment back, asphalt hemp fiber can also be used outside the wall filler 。 4. If the above methods are troublesome and the materials are hard to find, they can be used polyurethane Ab glue. This material is fast drying. Two materials, glue A and glue B, are mixed and poured into the settlement joint or construction joint, and hardened after 5 minutes. The higher the temperature, the faster the hardening. The ratio is 1:1. The ratio is calculated by weight. If more B glue is used, the hardening will be accelerated. Do not pour back the remaining materials after use. If the whole bucket is emptied, it will be wasted. Conclusion: Culvert leakage is easy to deal with except for cracks. Attention must be paid to the details when doing waterproof and plugging. After the treatment, it is recommended to apply the quick setting waterproof coating twice as a whole to achieve better external waterproof effect. How to deal with the plugging of culvert construction joints
