Description

Technical Field

[0001] The utility model belongs to the technical field of cement-based penetrating crystallization waterproof material construction tools, and more specifically, relates to a cement-based penetrating crystallization waterproof material dry spreading construction device. Background Art

[0002] Cement-based penetrating crystallization waterproofing material is a material used for waterproofing and reinforcing cement concrete structures. It is generally composed of cement, quartz sand, active substances, admixtures, etc. Its working principle is to generate water-insoluble crystals with cement hydration products to fill pores and block water seepage channels, thereby improving the density and waterproof performance of concrete structures. This material is usually used for waterproof protection of basements, pools, tunnels and other concrete structures. The main advantages of cement-based penetrating crystallization waterproofing materials include:

[0003] (1) Durability: It can provide long-term waterproofing effect. The active chemical substances contained in it use water as a carrier to continuously penetrate into the interior of the concrete. When there is no water, it enters a "dormant" state. When it comes into contact with water, it can react with the cement hydration products in the concrete structure to form water-insoluble crystals. The crystal structure formed by the reaction is not easily eroded or worn;

[0004] (2) Environmental protection: Compared with some traditional waterproof coatings, this material is generally more environmentally friendly because it does not contain harmful chemicals;

[0005] (3) Improve concrete strength: By increasing the density of concrete to form a closed waterproof layer, the durability, compressive strength and corrosion resistance of concrete are enhanced;

[0006] (4) Wide range of applications: Applicable to all kinds of concrete structures, including new construction and maintenance projects.

[0007] The main domestic standard for cement-based penetrating crystallization waterproof materials is GB18445-2012 "Cement-based penetrating crystallization waterproof materials", which stipulates the terms and definitions, technical requirements, test methods, quality control, etc. of penetrating crystallization cement-based waterproof materials to ensure that their quality and performance meet the standard requirements.

[0008] Common construction techniques for cement-based penetrating crystallization waterproof materials include: roller coating, brush coating, spray coating, and dry spreading. It is worth noting that in the dry spreading method, when the concrete is initially set, there is a layer of slurry about 5 to 6 mm high on the surface. The dry spreading area is demarcated and marked, and then the dry powder is sprinkled, and then smoothed with a grinder as it is spread. The dry powder is pressed into the concrete 6 to 7 mm deep, and the active substance may reach a depth of 20 mm after diffusion with water. After multiple water collection, multiple compaction, and multiple smoothing, the material is completely pressed on the concrete surface.

[0009] There are several controversies in dry spreading construction:

[0010] (1) Control of dry spreading amount: According to the provisions of GB 55030-2022 "General Specification for Waterproofing of Buildings and Municipal Engineering" and GB18445-2012 "Cement-based Penetrating Crystalline Waterproofing Materials", the thickness of the waterproof layer of the external coating penetrating crystallization waterproofing material shall not be less than 1.0 mm, and the amount shall not be less than 1.5 kg / m 2 . The dry powder has defects such as uneven thickness and unguaranteed dosage after manual spreading;

[0011] (2) Dust pollution and material waste: Directly dry-spread powder will diffuse in the air to form dust, which can easily have a negative impact on the construction environment and the health of workers. Some materials will float to other areas with the air, causing material waste;

[0012] (3) Surface strength cannot be guaranteed: Pressing dry powder into the concrete surface requires multiple compaction and smoothing. It cannot be guaranteed that the dry powder can be fully pressed into the concrete. Repeated construction on the concrete surface that has already begun to set may cause the surface strength of the concrete to decrease. Utility Model Content
