Template construction method capable of preventing wall of underground concrete pool from seepage

Abstract

The invention relates to the technical field of building construction, in particular to a template construction method capable of preventing the wall of an underground concrete pool from seepage. According to the template construction method, the four walls of a foundation pit formed after earth excavation of the underground concrete pool are used as external support points; internal support points are formed by support bars in the structure; and wall templates are pressed and pushed tightly from the inner sides and the outer sides through adjustable support systems instead of being fastened tightly in an opposite-pull manner. No opposite-pull bolt bars and water-stop steel plates are used in the structural wall body, so that material saving and environmental protection are achieved; a reinforcement cage is entirely enclosed by concrete, thereby completely eliminating tiny channels for water seepage and avoiding future leaking stoppage and repair work; a lot of work for manually welding opposite-pull bolts and water-stop steel plate strips is eliminated, thereby greatly reducing the workload, reducing the construction cost, shortening the construction period and improving the construction efficiency; removing rubber gaskets on the two ends of opposite-pull bolt bars is not needed any more; a waterproof material is used for blockage; and anti-rust treatment is performed on the surfaces at the ends of the opposite-pull bolt bars, so that the surfaces are smooth and the appearance quality is good.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a formwork construction method for preventing leakage of underground concrete pool walls. Background technique [0002] In the field of metallurgical building construction, various reinforced concrete underground pools are often encountered. At present, the widely used formwork support method for the pool wall is mainly to weld the waterproof steel sheet in the middle of the pull bolt rod. According to the statistics, the main reason for the leakage is that the concrete is not vibrated. Not compact, not in place, not tight formwork joints, grout leakage and other factors, the more important thing is that the welding of the steel plate water-stop piece in the middle of the tie bolt rod is not tight, and the water flows along the tiny gap between the tie bolt and the concrete.

[0002] In the field of metallurgical building construction, various reinforced concrete underground pools are often encountered. At present, the widely used formwork support method for the pool wall is mainly to weld the waterproof steel sheet in the middle of the pull bolt rod. According to the statistics, the main reason for the leakage is that the concrete is not vibrated. Not compact, not in place, not tight formwork joints, grout leakage and other factors, the more important thing is that the welding of the steel plate water-stop piece in the middle of the tie bolt rod is not tight, and the water flows along the tiny gap between the tie bolt and the concrete. Slowly infiltrate (permeate) in. If there is leakage, it will be a headache. It is very troublesome to deal with and repair. Not only the cost is high, but also cause certain adverse effects. The amount is large, and the bolt material is invested in one time, cannot be reused, and is not environmentally friendly. Therefore, in order to completely solve the problem of water leakage on the pool wall, in addition to external factors, it is the "channel" to prevent water infiltration
