Embodiment 1

[0044] The FS101 waterproof mortar of the FS101 waterproof mortar layer is made by mixing cement, sand and FS101 waterproof compacting agent dilution. Waterproof mortar is made by mixing cement: sand: FS101 waterproof compacting agent diluent according to the weight ratio of 1:1.5:0.45. FS101 waterproof compacting agent includes the following raw materials in parts by weight: 1.1 parts of sodium hydroxide; 0.4 parts of sodium oleate; 0.9 parts of sulfur; 0.8 parts of glycerin; 0.5 parts of polyacrylamide and 1.5 parts of water.

Embodiment 2

[0046] The FS101 waterproof mortar of the FS101 waterproof mortar layer is made by mixing cement, sand and FS101 waterproof compacting agent dilution. Mortar is made by mixing cement: sand: FS101 waterproof compacting agent diluent according to the weight ratio of 1:2.5:0.55. FS101 waterproof compacting agent includes the following raw materials in parts by weight: 1.3 parts of sodium hydroxide; 0.5 parts of sodium oleate; 1.2 parts of sulfur; 1.2 parts of glycerin; 0.8 parts of polyacrylamide and 1.9 parts of water.

Embodiment 3

[0048] The FS101 waterproof mortar of the FS101 waterproof mortar layer is made by mixing cement, sand and FS101 waterproof compacting agent dilution. Waterproof mortar is made by mixing cement: sand: FS101 waterproof compacting agent diluent according to the weight ratio of 1:1.5:0.55. FS101 waterproof compacting agent includes the following raw materials in parts by weight: 1.1 parts of sodium hydroxide; 0.4 parts of sodium oleate; 0.9 parts of sulfur; 1.2 parts of glycerin; 0.4 parts of aminotriethanol; 1 part of citric acid; 0.8 parts of polyacrylamide and 1.9 parts of water.

Abstract

The invention discloses a 360-degree underground waterproof structure system and a construction method thereof. A basement is arranged on a cushion layer and comprises a bottom plate, side walls, a top plate and a permanent protection wall; the bottom plate, the side walls and the top plate are formed by pouring waterproof concrete FS102; waterproof paste layers FS101 and waterproof mortar layers FS101 are arranged on the outer sides of the bottom plate and the top plate from inside to outside; a waterproof mortar layer FS101 and a waterproof paste layer FS101 are arranged between the bottom layer and the cushion layer from top to bottom; the permanent protection wall is used as a waterproof guide wall which is arranged on the outer side of the bottom plate; and a waterproof mortar layer FS101 and a fine aggregate concrete layer coping are arranged above the permanent protection wall from bottom to top. The 360-degree underground waterproof structure system is easy to operate; waterproof mortar FS101 and waterproof paste FS101 products are stable in performance and can effectively prevent water when smeared at the periphery of the basement; the permeability resistance is high, and retraction and cracking are not liable to cause; and by two-layer protection, water permeation can be effectively prevented, and the waterproofing stability of the basement is improved.

Description

technical field [0001] The invention belongs to the technical field of building construction structure waterproofing, and in particular relates to a 360-degree underground waterproofing structure system and a construction method thereof. Background technique [0002] With the acceleration of urbanization, considering the needs of expanding the use of space and stabilizing the building foundation, more and more buildings in the city have built basements, and the area is expanding and the depth is increasing. The basement bears all the loads of the building and will load Transferred to the soil layer, its stability is of great significance to the safety and service life of the building. The basement is very popular for its function of expanding the use space, but because it is built underground, the waterproof performance of the building will directly affect the use of the basement and the overall life of the building. [0003] Building waterproofing is the measures taken fro...
