Embodiment Construction

[0019] A preferred embodiment of the present invention takes an open-air overhead swimming pool as an example, which is described in detail as follows: see Fig. 1 , Fig. 2 and Fig. 3 .

[0020] 1. Swimming pool overview: The open-air overhead swimming pool is located on the top of the three-story frame structure of the swimming pool. The net size of the pool is: 50m long, 25m wide, and 1.2-2.0m deep. The pool wall is composed of frame columns and inter-column walls with a thickness of 300mm. The bottom of the pool is a steel concrete cast-in-place slab with a thickness of 300mm.

[0021] There is a large platform around the entrance of the swimming pool, with an elevation of 8.20m, a length of 69.34m from north to south, and a width of 55.54m from east to west. It has a frame beam-slab structure with a thickness of 120mm. The concrete of the swimming pool and platform is C30, and the impermeability is S8.

Abstract

The invention relates to a leakproof structure and a leakproof method for a reinforced concrete pool or well in the civil engineering. A shrinkage crack generated at the early stage of a concrete is restrained by a fiber by adding polypropylene fiber and low-alkali swelling agent in the concrete; a self-stress is produced inside the concrete during the hardening process of the cement by wet curing and the continuous production of a woodfordite which is the hydrated product of the swelling agent, so that a compensation shrinkage is produced to the concrete to prevent leakage and crack. The technology provided by this invention can be widely applied to different kinds of concrete structures which have leakproof requirements, in particular to poor or well structures, the external walls of basements, etc.

Description

Technical field: [0001] The invention relates to a reinforced concrete non-seepage pool well structure in civil engineering. Background technique: [0002] The cracks and leakage of reinforced concrete structures above and below the ground are major problems that hinder the quality of reinforced concrete structure pools. Relevant scholars and people in the engineering field try to solve the problem of shrinkage cracks from different angles, improve the anti-leakage ability of the structure, prolong its service life and exert its normal function. [0003] At the beginning, everyone focused on the use of waterproof coiled materials and waterproof coatings, but they could only treat the symptoms but not the root cause, ignoring the inherent potential of reinforced concrete structures. Concrete cracks due to drying shrinkage during hardening, which can lead to leakage or cracking of the structure. In recent years, domestic concrete anti-seepage engineering has begun to turn to...
