Underground garage waterproof and moisture-proof paving structure and construction process thereof

Abstract

The invention discloses an underground garage waterproof and moisture-proof paving structure and a construction process thereof. A plain concrete cushion layer, a flexible waterproof layer, a structural self-waterproof layer, a draining concrete layer, a flexible supporting layer, a crack-proof and moisture-proof layer and a floor surface layer are arranged from bottom to top in sequence. A drainage ditch is arranged in the structural layers from above the structural self-waterproof layer; the waterproof and moisture-proof paving structure laid by the process enables an underground garage to be waterproof and moisture-proof, high in anti-pressure ability and good in durability, and when cracks occur due to force majeure, the cracks cannot directly penetrate; and the function adaptability is high, and penetrative water and water vapor can be discharged by the screening concrete layer in time, so that the floor surface layer does not accumulate water and the influence on normal use is avoided.

Description

technical field [0001] The invention relates to the field of underground garage waterproof and moisture-proof technology, in particular to an underground garage waterproof and moisture-proof pavement structure and its construction technology. Background technique [0002] The current conventional basement floor includes a concrete cushion, a waterproof layer, a concrete structure floor, and a floor surface from bottom to top. Since the waterproof layer is usually an organic waterproof membrane, its strength is low, it is easily damaged during construction, and the durability of organic matter is poor. Long-term use will cause aging and damage, and damage to one point will lead to the failure of the entire waterproofing effect. For ordinary concrete structures, because the concrete contains a large number of pores and micro-cracks (at the micron level), moisture and water vapor in the basement often easily penetrate into the interior of the concrete, causing various durabilit...

AI Technical Summary

Problems solved by technology

Therefore, after a period of use, the floor of many basement garages often cracks and leaks and accumulates water; groundwater seeps through the capillary pores of the floor concrete to form water spots, and the underground garage is too humid; if the underground garage is made of resin such as epoxy or polyurethane The floor, often due to the penetration of water vapor or water seepage, will stretch the bonding surface between the resin floor film and the concrete floor, forming bulges and delamination (the resin film is impervious to air and water, and the water vapor permeated by the bottom plate is impenetrable. However, the floor membrane can only be stretched) leading to deterioration and damage of the floor, increasing maintenance and repair costs

At the same time, the ordinary concrete floor surface has poor density, low strength, and is prone to ash. Even if the underground water vapor or water has not penetrated, it may be debonded with the epoxy floor due to the long-term use of the concrete surface for ash, resulting in the deterioration of the floor and damage
