Embodiment 1
[0047] see figure 1, the present invention provides a technical solution: a waterproof and anti-seepage structure, the waterproof and anti-seepage structure includes a reinforced concrete layer 1, a leveling layer 2, an insulation layer 3, a waterproof layer 4, a water-permeable layer 5, a waterproof membrane 6, a decorative layer 7 and drainage holes 8; the waterproof and anti-seepage structure is as follows from bottom to top: reinforced concrete layer 1, leveling layer 2, thermal insulation layer 3, waterproof layer 4, permeable layer 5, waterproof membrane 6, decorative layer 7, the The waterproof and anti-seepage structure also includes a drain hole 8, a drain pipe 9 is provided at the drain hole, and a drain pipe hole 91 is provided at the drain hole; the drain pipe hole 91 is located at the junction of the waterproof layer 4 and the water-permeable layer 5 .
[0048] In this embodiment, specifically: the decorative layer 7 is laid by waterproof tiles, and gaps are left...
Embodiment 2
[0055] see Figure 2-4 As shown, different from Embodiment 1, the upper surface of the waterproof layer 4 is inclined upward from one end of the drain pipe 9;
[0056] In this embodiment, specifically: the angle θ of the inclination is 1°
[0057] In this embodiment, specifically: the drain pipe 9 is provided with a transparent cover 10, the transparent cover 10 includes an inner hole 101 and a transparent cover inner cavity 102, and the transparent cover inner cavity 102 is provided with water-absorbing and color-changing silica gel; The outer wall of the transparent cover 10 is provided with a first hole 103, a second hole 104, a grouting hole 105 and a hole leak-proof screen 106 of the transparent cover. The first hole 103 and the second hole 104 are located on the upper and lower surfaces of the transparent cover. , the grouting hole 105 communicates with the first hole 103 and the second hole 104 ;
[0058] Specifically, the outer wall of the transparent sleeve 10 has a...
Embodiment 3
[0060] The construction technology of embodiment 2 waterproof anti-seepage structure, comprises the steps:
[0061] S1: Reinforced concrete layer base surface and joint parts pretreatment, apply a dry powder type or YQ-MR type concrete interface agent, thickness 1mm;
[0062] S2: Insert a drainpipe into the drain hole, and lay a leveling layer with cement mortar and polypropylene anti-cracking fiber on the reinforced concrete structure layer. After 15 hours, sprinkle water for 8-11 days until it is completely solidified;
[0063] S3: Lay glass insulation board, phenolic foam board, polystyrene foam plastic board, aluminum silicate composite insulation coating or mud perlite, expanded vitrified beads, rubber powder polystyrene particles and mortar on the leveling layer Mixed laying, and the insulation layer formed by laying 75g / m glass fiber mesh;
[0064] S4: Lay a waterproof layer on the insulation layer. The waterproof layer is formed by laying waterproof coiled material, c...
