Method for waterproof construction of anti-floating anchor rod

The invention discloses a method for waterproof construction of an anti-floating anchor rod. The method comprises the steps that an additional waterproof layer is laid in the position, where the anti-floating anchor rod is located, of a concrete pad layer; large-area waterproof construction is conducted on the top surface of the additional waterproof layer; waterproof ointment is poured to the position of the anti-floating anchor rod; a protective layer is laid; and waterproof ointment is poured to the position of the anti-floating anchor rod again. Firstly, the additional waterproof layer is laid in the position, where the anti-floating anchor rod is located, of the concrete pad layer; secondly, large-area waterproof construction is conducted on the additional waterproof layer once, and the edges of the additional waterproof layer are also blocked and covered through a large waterproof area so that underground water cannot infiltrate upwards through the edges of the additional waterproof layer; the waterproof ointment is poured to the position of the anti-floating anchor rod, and thus a path along which underground water infiltrates upwards through the anti-floating waterproof anchor rod is blocked; the protective layer is used for protect the large waterproof area from damage; and finally, the waterproof ointment is poured to the position of the anti-floating anchor rod again, and thus new gaps between the concrete pad layer and the anchor rod are avoided. In this way, the waterproof effect of the position of the anti-floating anchor rod is greatly improved.
