A waterproof construction method for anti-floating anchor

Abstract

The invention discloses a waterproof construction method for an anti-floating anchor rod, which comprises the steps of: laying a waterproof additional layer at the anti-floating anchor rod of the concrete cushion layer; performing large-scale waterproof construction on the top surface of the waterproof additional layer; Waterproof ointment potting treatment; lay a protective layer; again use waterproof ointment potting treatment at the anti-floating anchor rod. Firstly, the waterproof additional layer is laid on the anti-floating anchor rod of the concrete cushion, and secondly, a large-scale waterproof construction is carried out on the waterproof additional layer, and the edge of the waterproof additional layer is also blocked and covered by the large-scale waterproofing, so that the groundwater cannot Penetrate upward through the edge of the waterproof attached layer, and pour waterproof ointment on the anti-floating anchor rod to block the upward penetration path of groundwater through the anti-floating anchor rod. The protective layer is used to protect the large surface waterproofing from damage, and finally Water the waterproof ointment on the anti-floating anchor again to avoid new gaps between the concrete cushion and the anchor. This has greatly improved the waterproof effect at the anti-floating anchor rod place.

Description

technical field [0001] The invention relates to the field of building waterproof construction, in particular to a waterproof construction method for anti-floating anchor rods. Background technique [0002] In the process of construction engineering, foundation and foundation construction, in order to eliminate or weaken the buoyancy effect of groundwater on the building and avoid the situation of the building floating up or the floor bulging, an anti-floating anchor is usually installed at the bottom of the foundation. One end of the anti-floating anchor rod passes through the concrete cushion and is fixed to the rock layer or soil at the bottom of the concrete cushion, and the other end is exposed on the top surface of the concrete cushion. However, because of the setting of the anti-floating anchor rod, groundwater will infiltrate along the upper foundation at the anti-floating anchor rod. [0003] In the usual waterproof construction, after the anchor rod construction is...

Problems solved by technology

However, due to the installation of anti-floating anchors, groundwater will seep into the foundation along the anti-floating anchors.

[0003] In the usual waterproof construction, after the anchor rod construction is completed, a waterproof layer is added on the bottom plate, but the groundwater will still pass through the gap and penetrate into the bottom of the waterproof layer along the gap between the anti-floating anchor rod and the concrete cushion.
