Embodiment Construction

[0025] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0026] refer to figure 1 and figure 2 , the application provides a construction method for foundation protection at the groundwater table, including:

[0027] Step 1, base surface treatment, cleaning the concrete surface and trimming the corners; specifically, use tools such as shovels and brooms to remove the garbage on the surface layer, and if you encounter difficult-to-remove stains, you can use solvents to clean them , the base layer has defects or sand running out, and it needs to be repaired to ensure the smoothness of the base layer. The yin and yang corners are rounded during leveling to ensure a smooth transition. It should be understood that the concret...

Abstract

The invention provides a construction method for foundation protection at an underground water level. The construction method comprises the steps that 1, a base surface is treated, specifically, the surface of concrete is cleaned, and all corner parts are trimmed; 2, primer brushing is conducted, specifically, a modifier and water are mixed according to a preset volume ratio, and the mixture is brushed on the surface of the concrete after uniformly stirring; and 3, preparing and brushing of a waterproof coating are conducted, specifically, the waterproof coating is prepared from a modifier and cement according to a preset weight ratio, uniformly stirred, and then brushed on the primer on the surface of the concrete. According to the construction method for foundation protection at the underground water level, waterproof protection on the concrete foundation can be guaranteed by using the prepared primer and the waterproof coating, and therefore protection such as water prevention, seepage prevention and moisture prevention on the foundation at the underground water level can be achieved. By means of the construction method, it is guaranteed that the whole coating is seamless, the coating can adapt to trace changes of a base layer, certain air permeability is achieved, and the phenomenon that a waterproof layer bulges even if the concrete foundation is wet is avoided.

Description

technical field [0001] The invention belongs to the technical field of concrete surface protection, and in particular relates to a construction method for foundation protection at an underground water level. Background technique [0002] The foundation (cement base or concrete base) at the groundwater level is in a long-term water-immersed environment, which will cause cracks or even fall off on the surface of the cement base. Some protections in the prior art will have certain waterproof and anti-seepage characteristics, but there will be cracks in some corners, the protection is not tight, and under the change of temperature difference, the change of base humidity will cause the waterproof layer to bulge, which in turn will lead to The occurrence of problems such as shedding. Seriously affect the basic quality and safety of the groundwater table, and seriously consume long-term maintenance costs. Contents of the invention [0003] In view of this, the object of the pre...
