Waterproof construction method of basement foundation cast-in-place pile head

Abstract

The invention discloses a waterproof construction method of a basement foundation cast-in-place pile head. The waterproof construction method particularly comprises the steps of base plane cleaning, pile head root grooving, vertical face capillary crystalline type waterproof coating and waterproof mortar smearing, base layer treating agent smearing, sealant smearing, reinforcing layer coiling, reinforcing layer shearing position sealing, large face waterproof construction, sealing of the combining portion of a large face and the pile head, pile head waterproof closing and fixing and high-permeability epoxy resin waterproof coating smearing. High-permeability epoxy resin waterproof coating, sealants, capillary crystalline type waterproof coating and waterproof mortar are smeared, waterproof rolls are laid, and rigid waterproofing and flexible waterproofing are achieved. Waterproofness of a foundation platform and waterproofneses of a bearing platform and the pile head are combined into one, and leakage points are prevented from happening to the pile head to guarantee project quality. The construction process is easy and convenient to operate, construction speed is high, no water moving layer exists, energy saving and consumption reducing are achieved, and the waterproofing term is prolonged.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a basement foundation filling pile head waterproof construction method. Background technique [0002] With the continuous development of urban construction, more and more high-rise buildings and super high-rise buildings are being constructed, the depth and number of layers of basement foundations are also increasing, and construction projects such as underground air defense, underground shopping malls, and underground parking lots are also increasing. The more common it is, the basement foundation leakage phenomenon it brings also increases thereupon, which seriously affects the quality of construction projects, and also brings great inconvenience to the normal use and management of basement foundations. Basic waterproofing is critical to the structure. A leaky foundation can create many problems, so waterproof your foundation right from the start. In particula...

AI Technical Summary

Problems solved by technology

The pile head waterproof membrane is wrapped around the reinforced concrete pile, the root of the pile foundation is sealed with sealing paste, and the pile surface is painted with CCCW waterproof paint. The combination of materials is relatively low, and the settlement of the structure will cause the large-surface membrane waterproof layer to separate from the pile foundation, and groundwater will directly enter the structure through the waterproof layer, causing water channels to easily form at the joints. The pile head surface adopts traditional CCCW waterproofing Paint brushing, the strength of the paint itself is low, and the adhesion between the pile surface and the structure is not good. The pile foundation is the main part of the structure's load-bearing. The waterproof function is almost lost, and at the same time, the connection of the pile head is not good, which has an impact on the safety of the structure
