A secondary structure anti-seepage and anti-leakage construction method

Abstract

The present invention relates to an anti-seepage and anti-leakage construction method of a secondary structure, which comprises the following steps: S1, base surface cleaning; S2, concrete sill masonry; S3, upper masonry construction; the construction process of the concrete sill includes : a, build reinforced concrete frame; b, build pouring formwork; c, pour impervious concrete; d, dismantle pouring formwork after initial setting of impermeable concrete; , the connection between the concrete sill and the base surface is not easy to form a large gap, the setting of the contact groove increases the contact area between the impermeable concrete and the base surface, and the lateral pressure generated during the forming process of the impermeable concrete is limited by the cutting plate Position, the template is not easy to deform, reducing the cracks caused by insufficient compaction of the template support, and the impermeable concrete is not easy to produce cracks after hardening.

Description

technical field [0001] The invention relates to the technical field of house construction, in particular to a secondary structure anti-seepage and anti-leakage construction method. Background technique [0002] In the process of house construction, some non-load-bearing masonry in the frame, shear wall, and frame-shear engineering, such as structural columns, lintels, parapets, filling walls, and partition walls, etc., need to be completed before decoration, called for the secondary structure. [0003] For example, the Chinese invention patent whose application publication number is CN110451890A has announced a secondary structure anti-seepage and anti-leakage construction method. The anti-seepage and leak-proof construction method of the secondary structure, the technical scheme is as follows: including steps: building a steel frame; building a pouring formwork; The impermeability of concrete structures. [0004] However, due to the shrinkage of concrete during the setti...

Problems solved by technology

[0003] For example, the Chinese invention patent whose application publication number is CN110451890A has announced a secondary structure anti-seepage and anti-leakage construction method. The anti-seepage and anti-leakage construction method of the secondary structure, the technical scheme is as follows: including steps: building a steel frame; Impermeability of concrete structures

[0004] However, due to the shrinkage of concrete during the setting and curing process, large gaps are easily formed at the junction of the secondary structure and the base surface, and the anti-seepage and anti-leakage effect is poor.
