Description

TECHNICAL FIELD

[0001] The utility model relates to the field of civil engineering waterproof drainage, specifically a capillary waterproof drainage board spreading device. BACKGROUND

[0002] In the field of foundation construction such as water conservancy projects, roadbed slopes, basement side wall backfilling soil and underground structure bottom plates, capillary waterproof drainage boards are often laid to form an effective waterproof drainage system. The traditional laying method relies on manual work, which is inefficient and difficult to guarantee laying quality, and is prone to problems such as wrinkles and hollowing, affecting the drainage effect of the soil. Therefore, a device is needed that is specifically used for foundation engineering and can efficiently and evenly spread capillary waterproof drainage boards.
