Description
Technical Field
The invention belongs to the field of building waterproof construction, and particularly relates to a coating type building foundation waterproof construction method.
Background
Nowadays, modern building technology mostly adopts reinforced concrete building, which has the advantages of earthquake resistance, fire resistance, sound insulation, etc., and most of roads, bridges, buildings and houses are of the type. However, although the reinforced concrete building has many advantages, fine cracks are easily generated due to stress accumulation and shrinkage in the concrete forming process, and the cracks gradually erode the internal reinforcing steel bar structure under the action of water permeation in underground water or soil, so that the durability of the structure is reduced, and the inner wall of the building is also subjected to a white phenomenon (commonly called as wall cancer), thereby seriously affecting the visual attractiveness.
Therefore, the perfect waterproof protection for building foundation is the direction of industrial efforts, the existing foundation waterproof engineering can be roughly divided into two types, one type is a rigid waterproof construction method, resin powder is added into cement, and a waterproof layer is formed after the cement is formed, but the phenomena of cracking, fine gaps and the like can occur under the repeated action of high temperature and low temperature of the cement, and water and gas enter the interior of the building along the cracks to cause the waterproof failure. Another type is a flexible waterproof construction method, for example, chinese patent No. 02153040.8 "foundation waterproof construction method and waterproof structure" is one of the so-called flexible waterproof construction methods; such construction methods include tarpaulins, waterproof blankets, self-adhesive waterproof membranes, water guide panels, coated waterproof materials, and the like. The waterproof cloth (membrane) is formed by bonding and splicing due to size limitation, so that the joint and the turning part of the male and female corners are particularly easy to damage, moisture is easy to permeate and expand from the damaged part, and poor adhesion between the surface of the waterproof cloth (membrane) and poured concrete is also a big problem; the water guide plate project has the problem of water seepage of indirect seams of plates, and once the water guide ditch is blocked by sundries such as silt, dry leaves and the like, the water-proof project is similar to a nominal project, so that more problems are caused. The ideal foundation waterproof construction method is a coating waterproof construction method, and an integrally formed coating film has no defects of seam cracking; the adhesive has excellent adhesiveness to heterogeneous materials, and the problem of leakage due to water pressure is completely solved; moreover, the waterproof coating film with high toughness and high extensibility can allow cracking of cement to a limited extent, and the waterproof effect is more durable. However, as the existing area of the constructed land is less and less, under the huge cost pressure of the inch of soil, the best use of the constructed area is desired, and finally, the distance between the constructed objects is too small, so that personnel and machines cannot pass through the constructed objects, the coating type waterproof construction method cannot be implemented, and the waterproof engineering is developed at once.

Detailed Description
The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.
Referring to fig. 1 and 2, a waterproof method for a building foundation according to the present invention includes the steps of, after a building foundation 1 is properly buried and before cement is poured:
and building temporary walls 2 around the building foundation 1.
The temporary wall 2 may be made of any one of cement board, wood board, calcium silicate board, plywood, brick mud board, polystyrene board, paper board, adhesive tape, adhesive film, non-woven fabric, fire blanket, waterproof blanket, cotton blanket, fiber blanket, brick wall, soil wall or cement wall.
And coating an interface modified primer layer 3 on the surface of the temporary wall 2 and the surface of the foundation 1 to strengthen the plain ground, penetrate and wet, level and fix dust.
Wherein the interface modified primer layer 3 is composed of a resin.
