But the basement leakage phenomenon happens occasionally, which is a common problem of building quality. The problem of basement leakage is solved, construction quality is improved, the stress deformation mechanism of the basement is understood, and the problem is solved.
The basement is easy to crack due to the shrinkage of the reinforced concrete and the influence of temperature difference, and the common treatment method comprises the following steps of 1) doping expansion type additives to generate certain pre-stress in the reinforced concrete, and reducing the influence of the shrinkage of the reinforced concrete and the influence of temperature difference; 2) the amount of the steel bars is increased to resist the shrinkage stress; 3) and arranging a deformation seam.
When the length of the basement is large, the methods are adopted. The deformation joints that we commonly place have the following problems: 1) the deformation joint has serious leakage, and the building waterproof measure is difficult to meet the requirement; 2) the arrangement of the deformation joint of the basement reduces the lateral constraint at the lower part of the building, is unfavorable for the lateral deformation of the building, and even makes the stress of the building complicated.
