Detailed Description
The present utility model will be described in detail below with reference to the drawings and the specific embodiments, so that those skilled in the art can better understand the technical solutions of the present utility model.
As shown in FIG. 1, a steel column for supporting is waterproof node of a reinforced concrete bottom plate downwards, which comprises a steel column component for supporting, wherein the steel column component for supporting penetrates through a plain soil ramming layer 1, a concrete cushion layer 2 and a pre-paving anti-adhesion waterproof coiled material layer 3 which are sequentially arranged from bottom to top, and in the embodiment, the pre-paving anti-adhesion coiled material layer 3 is a 1.5-thick pre-paving anti-adhesion coiled material (P type) layer. The reinforced concrete waterproof layer 7 is poured outside the steel upright post component for supporting, the plain soil ramming layer 1, the concrete cushion layer 2 and the pre-paved reverse-adhesion waterproof coiled material layer 3; the concrete used for the reinforced concrete waterproof layer 7 is impervious concrete.
The steel upright post assembly for supporting comprises a steel upright post 1 for supporting, an annular flange plate 5 sleeved on the outer wall of the steel upright post 1 for supporting, and a sealing plate 9 arranged at the top of the steel upright post 1 for supporting; the outer side of the sealing plate 9 is provided with a water-swelling adhesive tape 8. The joint of the steel upright post 1 for supporting and the pre-laid anti-adhesion waterproof coiled material 3 is sealed by a sealing material 4.
In the embodiment, plain soil is filled in the steel upright post for supporting; the water-swelling adhesive tape 8 is an SM water-swelling water-stopping adhesive tape, and the sealing material 4 is a modified petroleum asphalt sealing material; the annular flange plate 5 has a thickness of 10 mm. The top closure plate 9 is a circular steel plate with a thickness of 10 mm.
The pre-laid anti-adhesion coiled material layer 3 is arranged at the joint with the steel upright post 1 for supporting and extends vertically upwards for a certain length to be about 250-350 mm, and the sealing material 4 is arranged below the annular flange plate 5.
