Description

Technical Field

[0001] The utility model relates to the technical field of underground building construction, in particular to a multiple drainage system for a subway station. Background Art

[0002] In recent years, with the acceleration of urbanization and the gradual improvement of urban infrastructure, the subway has gradually become an important means of transportation. While bringing convenience to people's travel, it has also greatly alleviated the traffic pressure in the city. The construction of subway stations is difficult, and the waterproofing of subway stations has always been a top priority. For large-scale underground construction projects, construction joints, deformation joints, or inevitable construction joints and deformation joints will be reserved according to the actual construction conditions. At present, the more common waterproofing measures are to set waterstop strips, waterstop belts or waterstop steel plates at construction joints and deformation joints. Although this has largely prevented the problem of leakage at the joints of subway stations, the waterstop strips have poor water-stopping effect, the waterstop belts may be punctured by stones or steel bars in the concrete, and the welding of the waterstop steel plates is difficult to handle, all of which limit its water-stopping effect. There is an urgent need for a subway station joint anti-drainage device that can maximize the anti-drainage effect. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , 2 In the embodiment of the utility model, a multi-level drainage system for a subway station is provided, and the drainage system is arranged at the station body 10 and the station entrance and exit 20, and includes a side wall drainage structure and a joint drainage structure;

[0022] The side wall drainage structure includes a first transverse water retaining sill 32 arranged on the station main body ground 102 near the inner side of the station main body side wall 101, and also includes a first longitudinal water retaining sill 31 on the station entrance and exit ground 202 near the inner side of the station entrance and exit side wall 201, a first wall-separated groove 33 is arranged between the first transverse water retaining sill 32 and the inner side of the station main body side wall 101, and a cross-sectional groove is arranged between the first transverse water retaining sill 32 and the station entrance and exit ground 202.

[0023] 35, a second wall-separated groove 34 is provided between the first longitudinal water retaining sill 31 and the side wall 201 of the station entrance 20, the first wall-separated groove 33 and the second wall-separated groove 34 are both connected to the cross-sectional groove 35, and a floor drain 36 is provided in the cross-sectional groove 35;

[0024] The wall ditch collects leaking water, waste water, etc., and then discharges them from the floor drain 36 through the cross-sectional ditch 35, so as to achieve the combination of prevention and drainage and improve the overall water-stopping effect.

[0025] Multiple drainage devices ensure optimal drainage at the joints of subway stations, ensuring that the decoration remains dry at all times and that the base plate does not have water stains due to water leakage, thereby maintaining the best appearance of the building and extending its service life.

[0026] The drainage structure at the joint is arranged at the joint of the station body 10 and the station entrance and exit 20, including a second transverse water retaining sill 42 at the joint and a second longitudinal water retaining sill 41 connected to the second transverse water retaining sill 42, which are connected to the cross-sectional ditch 35 after being collected.

[0027] The joint of the station body 10 is a construction joint 50 between the station body 10 and the station entrance 20. The first set of second transverse water retaining sills 42 are arranged at the construction joint 50 to form a first set of transverse drainage channels. The construction joint 50 is provided with an expansion water stop glue 51.

[0028] The station entrance and exit 20 joint is a deformation joint 60 between the first cast and the second cast entrance and exit, and the second set of second transverse water retaining sills 42 are arranged at the deformation joint 60 to form a second set of transverse drainage channels. A water stop strip 61 is arranged in the deformation joint 60 .

[0029] It should be noted that, in this embodiment, the second group of second transverse water retaining sills 42 are arranged at the deformation joints 60 on the station entrance and exit ground 202, and both ends are in contact with the first longitudinal water retaining sills 31. Water leaking from the deformation joints 60 of the side walls 201 of the station entrance and exit 20 is collected through the second wall groove 34.

[0030] The side wall drainage structure and the joint drainage structure together with the expansion waterproof adhesive 51 and the water stop strip 61 form a multiple drainage prevention device, so that the drainage prevention effect at the joint of the subway station is optimal.

[0031] Preferably, a cover plate 43 is placed above the drainage structure at the joint to reserve a certain flat space for the finished surface of the decoration, so as to facilitate the smooth completion of subsequent decoration.

[0032] The cover plate 43 and the special water retaining sill are bonded with sealant to prevent the cover plate 43 from leaking and wetting the floor decoration due to inadequate shielding; the floor drain 36 can be checked and replaced regularly to ensure that the drainage effect is not affected by clogging or rusting due to impurities contained in waste water such as leaking water.

[0033] The working principle of the utility model is as follows: the utility model adopts a double drainage method of side wall drainage and joint drainage. Water leaking from the side wall 101 of the station body falls along the side wall 101 of the station body to the ground 102 of the station body, and can be directly collected through the first wall-separated groove 33 between the side wall 101 of the station body and the first transverse water retaining sill 32. Water leaking from the side wall 201 of the station entrance and exit 20 falls along the side wall 201 of the station entrance and exit 20 to the ground 202 of the station entrance and exit, and can be directly collected through the second wall-separated groove 34 between the side wall 201 of the station entrance and exit 20 and the first longitudinal water retaining sill 31, and then discharged from the floor drain 36 through the cross-sectional groove 35.

[0034] When the leakage water penetrates the expansion water stop glue 51 and the water stop strip 61 in the construction joint 50 and the deformation joint 60 and soaks the bottom plate decoration layer, the drainage structure at the joint and the expansion water stop glue 51 and the water stop strip 61 form a multiple drainage prevention device, which is collected by the second transverse water retaining sill 42 and collected by the second longitudinal water retaining sill 41 to the cross-sectional ditch 35, so that the drainage prevention effect at the joint of the subway station is optimal.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
