[0019] The technical scheme of the utility model will be described clearly and completely below in combination with the drawings of the utility model, and obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model. In the description of the utility model, it is necessary to explain that the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship of the utility model product when being used normally, and only for the convenience of describing the utility model or simplifying the description, and not indicate or imply that the indicated device or element must have a particular orientation, be constructed or operated in a particular orientation, therefore, it can not be understood as the limitation of the utility model.

[0020] In the description of the utility model, still need to explain, unless another explicit provision and limit, term "arrange", "install", "connect" should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, also can be electrical connection;Can be direct connection, also can indirectly connect through intermediate medium, can be two element internal communication。For ordinary skilled person in the art, can understand the specific meaning of the above-mentioned term in the utility model according to specific circumstances.

[0021] Referring to Figs. 1-3 The utility model relates to a post-pouring zone grouting type waterstop structure, which has a post-pouring zone bottom plate 1, a plurality of grouting pipes 2 arranged side by side are embedded in the post-pouring zone bottom plate, and adjacent grouting pipes are arranged at a certain distance and are parallel to each other; a plurality of grouting hole structures 3 are further arranged on the post-pouring zone bottom plate, each grouting hole structure comprises a grouting nail base 6, a grouting nail 7 is welded on the grouting nail base, a one-way check valve 9 is arranged inside the grouting nail, and a shunt grouting pipe 4 is further embedded below the inside of each grouting nail; the shunt grouting pipe is connected to each grouting pipe at the same time. Further, the grouting pipes are arranged longitudinally in the utility model, the shunt grouting pipes are arranged transversely, and the connection parts of the shunt grouting pipes and each grouting pipe are connected by a four-way joint 5. Further, a sealing nut 8 is further arranged on the grouting nail in the utility model, and a guide hose 10 is connected to the outer port of the grouting nail. Further, the adjacent grouting pipes are arranged at a distance of 1-3 m in the utility model. Further, the grouting hole structures are longitudinally distributed on the post-pouring zone bottom plate and are arranged at a distance of 2 m from each other in the utility model. Further, water-soluble infiltration and consolidation type high-molecular composite waterproof material slurry is injected into the grouting hole structures in the utility model.

[0022] The utility model is a structure that is embedded and preset in advance, and the size of the post-pouring zone bottom plate is used to determine how many grouting pipes are embedded therein, and a proper number of grouting hole structures are preset at the middle position; a shunt grouting pipe is embedded in each group of grouting hole structures, and the shunt grouting pipe is connected to each grouting pipe; during use, a guide hose is sleeved on the port of each grouting nail, a sealing nut is used to seal the root of the grouting nail, and then grouting can be performed.

[0023] Grouting is a grouting method in which waterproof grouting material is poured from the backwater surface to the water-facing surface and a waterproof layer is formed on the water-facing surface. The utility model uses water-soluble infiltration and consolidation type high-molecular composite waterproof material grouting material. Imported special grouting equipment is used to ensure the quality. The utility model uses a one-way check valve, which can timely and automatically block the slurry in the hole.

[0024] Before grouting, drainage equipment should be prepared to ensure that groundwater can be discharged in time when groundwater gushes out, so as to ensure the safety of internal equipment. Before construction, the equipment protection should be done according to the requirements of the owner party. If possible, the owner party should arrange special personnel to protect the equipment. When grouting, the grouting should be interval, so that it is more dense.
