No-pollution internal-wall concrete water tank made of HDPE boards

Abstract

The invention discloses a no-pollution internal-wall concrete water tank made of HDPE boards, which comprises a steel concrete bottom board, steel concrete circular side wall upwardly extending in the mode of surrounding the circumference of the bottom board, and a steel concrete top board on the top of the circular side wall, wherein the bottom board, the circular side wall and the top board form an integrated water storage chamber, and the internal wall of the water storage chamber is provided with water inlets and water outlets. The difference is as follows: the bottom board and the circular side wall are respectively and fixedly connected with an HDPE internal bottom board and an HDPE circular internal side board corresponding to the sizes of the bottom board and the circular side wall, and the internal bottom board and the internal side board are welded in a heat melting mode or a buckling mode. The water tank enables the HDPE internal wall and the concrete wall to be tightly combined and firmly fixed into a whole by previously embedding a plurality of HDPE bars. The water tank uses the internal wall of HDPE boards, is not harmful to the human body, has good mechanicalness, heat resistance, permeating resistance and durability and smooth surface, does not generate the defective element of water corrosion, and enables the water quality to be more sanitary and safer.

Description

technical field [0001] The invention relates to a water tank, in particular to a water tank using HDPE. Background technique [0002] At present, most of the drinking water for residents in large, medium and small cities in my country is supplied through roof water tanks and underground storage tanks. It is easy to cause secondary pollution of water sources and it is difficult to clean, so that the water quality cannot meet the high standard requirements for direct drinking. [0003] In order to improve the quality of drinking water for urban residents, some large cities have begun to renovate building concrete water tanks, and use stainless steel materials to treat the inner walls of the water tanks. However, this method has complex processes, long production time, and high investment costs. Not suitable for promotional use. And according to the use of water quality and water storage, it is found that the long-term use of the water tank will cause serious acidification of ...

[0002] At present, most of the drinking water for residents in large, medium and small cities in my country is supplied through roof water tanks and underground storage tanks. It is easy to cause secondary pollution of water sources and it is difficult to clean, so that the water quality cannot meet the high standard requirements for direct drinking

[0003] In order to improve the quality of drinking water for urban residents, some large cities have begun to renovate building concrete water tanks, and use stainless steel materials to treat the inner walls of the water tanks. However, this method has complex processes, long production time, and high investment costs. Not suitable for promotion

And according to the use of water quality and water storage, it is found that the long-term use of the water tank will cause serious acidification of the welding parts of the stainless steel, and the chlorine gas used for disinfection can cause corrosion of the stainless steel material, resulting in very obvious deposits in the water tank, pollution Decreased water quality in tanks, hygienic quality
