Construction method for impermeability leakage prevention of secondary structure

Abstract

The invention relates to the field of house construction, and provides a construction method for impermeability leakage prevention of a secondary structure aiming at the problem that an impermeable effect of a secondary structure is reduced because a waterproof layer easily falls off. The technical solution is as follows: the method comprises the following steps: step 1, building a reinforced barframe; step 2, building a casting template; step 3, pouring impermeable concrete; step 4, disassembling a casting template after the impermeable concrete is initially settled; and step 5, sprinkling water for curing, wherein the impermeable concrete comprises the following components, in parts by mass: 100 parts of Portland cement, 300-400 parts of coarse aggregate, 200-250 parts of fine aggregate, 100-150 parts of a nano filler, 30-50 parts of an adhesive, and 90-110 parts of water. According to the method provided by the invention, the nano filler is added into the impermeable concrete to fill gaps and fine pores in the concrete structure, the adhesive fills crack fine pores in the concrete structure, so that the concrete structure is very compact, the impermeability of the concrete structure is improved, even without addition of a waterproof layer, the impermeable effect is better and more stable, and the construction is more convenient.

Description

Technical field [0001] The invention relates to the field of house construction, in particular to a secondary structure anti-seepage and anti-leakage construction method. Background technique [0002] Secondary structures are some non-load-bearing concrete structures in frame, shear wall and frame-shear projects. [0003] Some secondary structures located outdoors, such as external walls, are mainly used as partitions. The secondary structure separates indoors and outdoors. In order to keep the indoor space dry and comfortable, secondary structures located outdoors, such as external walls, need to be kept well. Impermeability, while the general concrete structure has cracks, pores and other poor impermeability, it is necessary to add an additional waterproof layer, but the waterproof layer is generally organic, which is easy to separate and fall off from the inorganic concrete structure, resulting in the impermeability of the secondary structure The effect is reduced, so there is ...

Problems solved by technology

[0003] Some secondary structures located outside, such as exterior walls, mainly play the role of partition, and separate indoor and outdoor through secondary structures. In order to keep the indoor space dry and comfortable, the secondary structures located outside such as exterior walls need to be kept in good condition. Impermeability, and the general concrete structure has poor impermeability such as gaps and pores, and an additional waterproof layer is required, but the waterproof layer is generally organic, which is easy to separate and fall off from the inorganic concrete structure, resulting in the impermeability of the secondary structure Effectiveness declines, therefore, there is room for improvement
