Embodiment 1

[0039] Embodiment one: the construction method of bentonite waterproof blanket of the present invention, the main steps are as follows:

[0040] (1) Base surface treatment

[0041] Base surface treatment should be carried out before laying / hanging, including base surface leakage water treatment and base surface flatness treatment.

[0042] 1. The treatment of base surface leakage water shall meet the following requirements:

[0043] The laid base should be rigid, such as concrete or cement mortar, the concrete strength grade should not be less than C15, and the cement mortar strength grade should not be lower than M7.5. The base surface after treatment is allowed to be wet, but there must be no point-shaped water leakage or linear water flow;

[0044] The treatment of seepage water on the base surface should mainly focus on plugging, and if it is difficult to plug, temporary drainage measures can be taken. The temporary drainage pipes used should be embedded in the groove o...

Abstract

The invention relates to a construction method of a bentonite waterproof blanket. The method includes the steps of base surface treatment, waterproof blanket laying, lap seam treatment, head swing protection and connection, end closing treatment, hollowing treatment and the like. When dealing with lap seams, it is required that the waterproof blankets be naturally lapped, the lap width should not be less than 100mm, and the lap seams cannot be set at the corners; the reserved length of waterproof blankets should be 200-400mm longer than that of steel bars, and should be greater than 500mm. ~800mm, and sealed with edge strips; temporary protection is provided for façade head shakes and plane head shakers; waterproof blankets are laid to the top of the facade for end closure treatment, and the closures are fixed. The construction method of the invention has reasonable technology, can be permanently waterproofed, is simple in method, saves labor and materials, has the same long service life as the structure, has secondary waterproofness, and can form an active waterproofing system. The construction cost is low, the benefit is high, and the application range is wide, and it is suitable for various waterproof requirements of underground waterproof projects.

Description

1. Technical field: [0001] The invention relates to a building material construction method, in particular to a construction method of a bentonite waterproof blanket. 2. Background technology: [0002] The mineralogy name of bentonite is montmorillonite, commonly known as Guanyin soil. It is a hydrous clay mineral mainly composed of montmorillonite. Because of its special properties, such as swelling, cohesiveness, adsorption, catalytic, thixotropy, Suspension and cation exchange properties, etc., also known as "universal soil". [0003] Bentonite is one of the minerals with the strongest crystal structure variation among clay minerals. The slow scanning of diffractometer shows that the particle size of montmorillonite is close to the nanometer level. Compactness, permanent waterproofness, easy construction, environmental protection and other properties are more and more widely used in waterproofing. [0004] High Density Polyethylene, the English name is "High Density Pol...
