A construction method combining waterproofing and drainage in basement

Abstract

The invention discloses a combined construction method of basement waterproofing and drainage, which comprises waterproofing and hydrophobicity of the basement floor and waterproofing and hydrophobicity of the basement side walls. The construction method for the combination of waterproofing and drainage for a basement proposed by the present invention successfully drains all the seepage water under the foundation floor to the water collecting well through the waterproofing, water-repellent, drainage system of the coiled material and the rigid waterproof concrete floor under the foundation floor. When the water level in the collecting well reaches a certain height, the drainage pump will automatically start to drain, which ensures the dry state and normal use of the basement floor, and the basement base floor drainage system can be inserted backfill at any time after the completion of the basement construction. It is not necessary to wait until the basement is completely completed and checked for no leakage before carrying out the above work, which improves work efficiency and construction period.

Description

technical field [0001] The invention belongs to the field of waterproofing and drainage in building construction, and in particular relates to a construction method combining waterproofing and drainage in a basement. Background technique [0002] Leakage of basement exterior walls and floors is one of the common quality problems. At present, the basement waterproof layer is mainly composed of rigid waterproof and flexible waterproof layers. Because the concrete rigid waterproof layer will inevitably produce certain micro-cracks, while the flexible waterproof layer is prone to aging due to weak lap joints, damage, membrane waterproofing and coating waterproofing, it is difficult to maintain the waterproof effect in the later stage, and in fact cannot form a real The enclosure system makes the buildings whose basement depth is below the groundwater level prone to water leakage; the traditional waterproofing methods all adopt the "blocking" method, which cannot permanently solv...

Because the concrete rigid waterproof layer will inevitably produce certain micro-cracks, while the flexible waterproof layer is prone to aging due to weak lap joints, damage, membrane waterproofing and coating waterproofing, it is difficult to maintain the waterproof effect in the later stage, and in fact cannot form a real The enclosure system makes the buildings whose basement depth is below the groundwater level prone to water leakage; the traditional waterproofing methods all adopt the "blocking" method, which cannot permanently solve the water leakage problem, which seriously affects the quality of construction projects and also It brings great inconvenience to the normal use and management of the basement
