Embodiment Construction

[0026] The construction method of the all-steel mold cast-in-place ultra-thin concrete underground anti-seepage wall and its construction method of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] An all-steel form cast-in-place ultra-thin concrete underground anti-seepage wall and its construction method are characterized in that the construction steps are as follows:

[0028] Step 1: First, use the lifting device (1) to lift the high-frequency vibrating hammer (2), the special holder (3), and the ultra-thin hollow countersunk (4), and use a thin iron wire to lift the pointed pile point (5 ) is installed below the ultra-thin hollow counterbore (4);

[0029] Step 2: Move the lifting equipment (1), lift the first ultra-thin hollow countersunk (4) and place it at the predetermined position, and use the auxiliary positioning device (6) to perform auxiliary adjustment and positioning, and start t...

Abstract

The invention relates to a whole steel-mould cast-in-place ultra-thin concrete underground impermeable wall and a construction method thereof, high-frequency vibratory hammer is adopted to make specially wall formation of whole steel-mould, the deficiency of the existing technology is overcome, the wall formation can be completed without large-scale machine equipment, the whole steel-mould is adopted to avoid mud protection and mud pollution, inner and outer steel-mould is arranged in love sink hole opener to guarantee the side wall of the impermeable wall vertical, the quality of seam is guaranteed, the unearthed structure manufacturedspecially is adopted, the soil-squeezing effect is reduced, at the same time the impermeable walls of different thickness are realized according to requirement, the perfect construction of the impermeable wall is most reliable in economy and technology.

Description

technical field [0001] The invention relates to the field of civil engineering construction, in particular to the construction field of underground anti-seepage walls, in particular to an all-steel mold cast-in-situ ultra-thin concrete underground anti-seepage wall and a construction method thereof. Background technique [0002] At present, with the rapid development of society, energy is increasingly scarce. Hydropower is clean energy, renewable, non-polluting, and low in operating costs. It is convenient for power peak regulation and is conducive to improving resource utilization and comprehensive economic and social benefits. Under the situation that the earth's traditional energy sources are becoming increasingly tense, countries around the world generally give priority to the development of hydropower and make great use of hydropower resources. China ranks first in the world in terms of both the proven reserves of hydropower resources and the potential development of hy...
