Technical Field

The invention relates to the technical field of building waterproofing, in particular to a waterproof construction method for an anti-floating anchor rod node.

Background

With the development of urban construction, the development of underground spaces including underground garages, underground malls and the like is more and more emphasized; large-span spatial structures such as large public buildings, stadiums and the like have the problem of balancing the buoyancy of large-area areas and underground water. When the self weight of the structure is not enough to resist the buoyancy generated by underground water, the construction method of adding the anti-floating anchor rod is generally adopted for treatment, but the node of the anti-floating anchor rod and the bottom plate is always a weak link for a waterproof system.

Waterproof is always the most problematic part of construction quality in the construction process of buildings, if the waterproof construction quality is not strictly controlled in the construction process, more energy and money are spent for maintenance in later maintenance, so the waterproof is the most important part of the construction. When the groundwater level is higher, the anchor rod is often adopted to resist the buoyancy brought to the building by groundwater, but because the anti-floating anchor rod needs to penetrate the basement bottom plate waterproof layer, the water seepage can be caused well in the treatment. Therefore, the waterproof treatment of the anti-floating anchor rod is the treatment key point of basement waterproofing engineering.
