[0019] Embodiment: As Figures 1-4 shown, the present invention provides a leak-proof pre-embedded pipe joint structure, which includes a bottom pipe 1.

A fixing ring 74 is fixedly installed at the bottom end of the inner ring of the connecting hole 72. First, install the bottom pipe 1 on the lower surface of the floor slab, and thread the extension pipe 2 into the bottom pipe 1. The extension pipe 2 can be adjusted in spiral lifting according to the thickness of the floor slab. Then, insert the connecting pipe into the bottom end of the bottom pipe 1 and fix it with waterproof glue. Next, according to the position of the bottom end of the upper connecting pipe, rotate the connecting pipe sleeve 71 to align the connecting hole 72 in the connecting pipe sleeve 71 with the bottom end of the connecting pipe, and insert the bottom end of the connecting pipe into the connecting hole 72 in the connecting pipe sleeve 71, so that the bottom end of the connecting pipe contacts the upper surface of the fixing ring 74 in the connecting hole 72, and fix it with waterproof glue. The fixing ring 74 can make the bottom end of the connecting pipe be tightly connected with the connecting pipe sleeve 71, effectively preventing water from seeping out. If water leakage occurs at the connection between the connecting pipe and the connecting pipe sleeve 71, the water leakage holes 73 on the connecting pipe sleeve 71 can drain water for the second time to prevent water from seeping out.

[0021] By adopting the above technical solution, the waterproof groove 41 can effectively prevent the water from seeping and leaking at the connection between the extension pipe 2 and the bottom pipe 1 and penetrating to the lower layer.
[0022] A plurality of annularly distributed drain holes 42 are opened at the waterproof groove 41 on the bottom pipe 1, and the drain holes 42 are communicated with the inside of the bottom pipe 1.
[0023] By adopting the above technical solution, the accumulated water in the waterproof groove 41 can flow into the bottom pipe 1 through the drain holes 42.
[0024] A plurality of annularly distributed drain grooves 43 are opened on the inner wall of the bottom pipe 1, and the top ends of the drain grooves 43 are communicated with the corresponding drain holes 42.
[0025] By adopting the above technical solution, the accumulated water in the waterproof groove 41 can flow into the bottom pipe 1 through the drain hole 42 and the drain groove 43.
[0026] A diversion ring 8 is fixedly installed in the bottom pipe 1. The inner ring of the diversion ring 8 is in an inverted conical shape, and the diversion ring 8 is located at the bottom end of the drain groove 43.
[0027] By adopting the above technical solution, the diversion ring 8 can tightly connect the top end of the connecting pipe with the bottom pipe 1, effectively preventing water from seeping out. The diversion ring 8 can also divert the water at the drain groove 43 into the connecting pipe.
[0028] A plurality of annularly distributed mounting ears 3 are fixedly installed on the outer periphery of the bottom end of the bottom pipe 1 and the outer periphery of the top end of the extension pipe 2. A mounting hole 31 is provided on each of the plurality of mounting ears 3, and the mounting hole 31 is a threaded hole.

[0033] By adopting the above technical solution, during construction, the sealing cover 5 can be covered on the extension pipe 2 to prevent sundries such as construction materials from falling into the connecting pipe through the extension pipe 2 and causing pipeline blockage.
[0034] Working principle: When the utility model is in use, first, the bottom pipe 1 is fixedly installed on the lower surface of the floor slab by screws. Then, the extension pipe 2 is threadedly installed inside the bottom pipe 1. The extension pipe 2 can be adjusted in spiral lifting according to the thickness of the floor slab. Then, the connecting pipe is inserted into the bottom end of the bottom pipe 1 and fixed with waterproof glue. Then, according to the position of the bottom end of the upper connecting pipe, the connecting pipe sleeve 71 is rotated so that the connecting hole 72 inside the connecting pipe sleeve 71 is aligned with the bottom end of the connecting pipe, and the bottom end of the connecting pipe is inserted into the connecting hole 72 inside the connecting pipe sleeve 71, so that the bottom end of the connecting pipe contacts the upper surface of the fixing ring 74 inside the connecting hole 72, and is fixed with waterproof glue. The fixing ring 74 can tightly connect the bottom end of the connecting pipe with the connecting pipe sleeve 71, effectively preventing water from seeping out. If water leakage occurs at the connection between the connecting pipe and the connecting pipe sleeve 71, the water leakage hole 73 on the connecting pipe sleeve 71 can conduct secondary drainage to prevent water from seeping out;
[0035] The waterproof groove 41 can effectively prevent the water leakage at the connection between the extension pipe 2 and the bottom pipe 1 from seeping into the lower layer.
