Referring to fig. 1 and 2, for the utility model discloses an underground continuous wall waterproof construction, including a plurality of vertical wall bodies 1, a plurality of wall bodies 1 end to end splice together, and one side of a plurality of wall bodies 1 all is equipped with a plurality of vertical infiltration pipes 2, and the week side of a plurality of infiltration pipes 2 is all fixed in one side of wall body 1. All pre-buried horizontal drain pipe 3 that has in a plurality of walls 1, drain pipe 3 is close to the downside setting of wall body 1, and the week side of a plurality of drain pipes 3 all wraps there is heat preservation 10, and heat preservation 10 is optional for the rock wool material. All the intercommunication has a plurality of connecting pipes 4 on a plurality of drain pipes 3, and the one end that drain pipe 3 was kept away from to a plurality of connecting pipes 4 communicates with a plurality of infiltration pipes 2 respectively, and connecting pipe 4 is the bottom of infiltration pipe 2 with the intercommunication department of infiltration pipe 2, and the one end that connecting pipe 4 slope set up and communicate with drain pipe 3 is lower. The drain pipes 3 between the adjacent walls 1 are communicated with each other. When the groundwater of wall body 1 one side oozes to wall body 1 one side, groundwater is at wall body 1 shelters from down and the accumulation in one side of wall body 1 this moment, groundwater is in infiltration effect of infiltration pipe 2 and is collected in infiltration pipe 2 this moment, groundwater in infiltration pipe 2 is in inflow drain pipe 3, groundwater flows in drain pipe 3, finally is arranged in sewer pipe (not shown in the figure), the groundwater content of wall body 1 one side has been reduced to groundwater is difficult for permeating wall body 1 from the concatenation department of wall body 1.

Referring to fig. 2 and 3, a connecting groove 6 with vertical length is formed in one side of the wall body 1, a connecting strip 7 with vertical length is fixed on one side of the wall body 1 departing from the connecting groove 6, and a splicing fit is formed between the adjacent wall bodies 1 through the connecting groove 6 and the connecting strip 7. And rubber water stops 8 are arranged at the bottom and the wall of the connecting groove 6. The connecting strip 7 is in contact with the groove bottom and the groove wall of the connecting groove 6 through the rubber water stop belt 8, so that the gap between the connecting strip 7 and the connecting groove 6 is reduced, and underground water is not easy to seep through the wall body 1 from the splicing part between the wall bodies 1.

Referring to fig. 2 and 4, the uniform ends of the drain pipes 3 in the plurality of wall bodies 1 penetrate out of the wall bodies 1, the other ends of the drain pipes are located in the wall bodies 1, and a connecting hole 5 communicated with the drain pipe 3 is formed in a position, extending away from the drain pipe 3, of the wall body 1. And the connecting hole 5 is arranged at the bottom of the connecting groove 6, so that when the connecting strip 7 is inserted into the connecting groove 6, the drain pipes 3 are inserted into the connecting hole 5, the plurality of drain pipes 3 are communicated, and the joints of the drain pipes 3 are arranged in the wall body 1, thereby reducing the possibility of water leakage at the joints of the drain pipes 3.

Referring to fig. 1, one side of the wall 1, which faces the permeation tube 2, is provided with waterproof geotextile 9, and the waterproof geotextile 9 is used for shielding the gap where the adjacent walls 1 are connected. The waterproof geotextile 9 shields the connecting gap between the walls 1, thereby reducing the possibility that the groundwater seeps into the connecting part of the walls 1 and the possibility that the groundwater seeps into the wall 1 and deviates from the permeation tube 2.

The implementation principle of the embodiment is as follows: the groundwater of wall body 1 one side oozes when wall body 1 one side, groundwater is at wall body 1 shelters from down and the accumulation in one side of wall body 1 this moment, groundwater is in infiltration effect of infiltration pipe 2 and is collected in infiltration pipe 2 this moment, groundwater in infiltration pipe 2 is in inflow drain pipe 3, groundwater flows in drain pipe 3, finally is arranged to the sewer pipe in, has reduced the groundwater content of wall body 1 one side to groundwater is difficult for oozing wall body 1 from the concatenation department of wall body 1.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
