[0002] In underground structure engineering, roof post-pouring hole leakage is a relatively common problem. The installation of conventional steel plate water stop belt is limited, which leads to that water stop measures are not fully considered or water stop measures are imperfect, and it often becomes the main leakage point of basement structure. Such leakage not only affects the use function of building, but also may pose a potential threat to the safety of structure. Therefore, it has important practical significance to deeply analyze the reasons for the leakage of roof post-pouring hole of underground structure and take effective solutions.

[0017] like Figs. 1-2 As shown, an underground structural roof slab that facilitates water sealing of post-cast holes includes a roof slab body 1 and a water-stop steel plate 2. The roof slab body 1 contains reinforcing beams 3, some of which are exposed outside the sidewalls of the roof slab body 1. The exposed reinforcing beams 3 have an A-section 4 perpendicular to the roof slab body 1. The water-stop steel plate 2 has a first part 2-1, a second part 2-2, and a third part 2-3. One end of the first part 2-1 is fixedly connected to the second part 2-2. The end of the second part 2-2 away from the first part 2-1 is connected to the third part 2-3. The angle between the third part 2-3 and the second part 2-2 is 90°, and the angle between the first part 2-1 and the second part 2-2 is 45°. The angles between the first part 2-1 and the second part 2-2, and between the third part 2-3 and the second part 2-2, are located on the same plane. The side of the third part 2-3 facing away from the second part 2-2 can be welded to the A-section 4.

[0018] In this embodiment, when installing, first install the roof body 1, then weld the third part 2-3 of the water stop steel plate 2 on the A part 4, the third part 2-3 is designed to facilitate welding with the A part 4, so that the third part 2-3 has more welding area with the A part, so that the welding is more firm after welding; and because the third part 2-3 is perpendicular to the second part 2-2, so that the third part 2-3 is welded with the beam steel bar 3, and the second part 2-2 is parallel to the upper surface of the roof body 1, so as to play a role of water stop at the post-pouring hole, and the first part 2-1 is arranged to enable water to stay on the second part 2-2. After the third part 2-3 is welded with the A part 4, the beam steel bar 3 and the welding part of the third part 2-3 are sealed with concrete to form a solidification zone 7, and then a water-swelling sealing water stop glue 6 is arranged on the side of the solidification zone 7 away from the roof body 1, so that the post-pouring hole is completely sealed, so that the waterproofing has two lines of defense, one is the water stop steel plate 2, and the other is the water-swelling sealing water stop glue 6, thereby improving the waterproofing effect.

[0019] As a preferred mode, the beam steel bar 3 in the roof body 1 is woven into a cuboid net shape, one end of the cuboid net shape extends to the outer side wall of the roof body 1, and the other end of the cuboid net shape is located in the roof body 1. The purpose of weaving in this way is to make the roof body 1 more firm. And the end of the cuboid net shape located outside the roof body 1 is to be welded with the third part 2-3.

[0020] As a preferred mode, the roof body 1 is further provided with a rebate 5 on the outer side wall where the cuboid net shape extends, and the rebate 5 is located on one side of the cuboid net shape. The rebate 5 is arranged below the water stop steel plate 2, and the purpose is to facilitate the lapping (splicing) of the two roof bodies 1.

[0021] As a preferred mode, when the water stop steel plate 2 is welded on the A part 4, the rebate 5 is located on one side of the free end of the second part 2-2 away from the third part 2-3.

[0022] As a preferred mode, the roof body 1 is made of concrete.

[0023] As a preferred mode, the length of the cuboid net shape protruding from the outer side wall of the roof body 1 is less than the diameter of a single steel bar constituting the cuboid net shape. This arrangement can reduce the volume of the solidification zone 7, thereby facilitating operation, because the larger the volume of the solidification zone 7, the longer the solidification time, which will affect the construction period.

[0024] As a preferred manner, the distance from the free end of the first portion 2-1 to the second portion 2-2 is less than the distance from the free end of the third portion 2-3 to the second portion 2-2. This is to reduce the mass of the non-welded portion of the water-stop steel plate 3, so that the water-stop steel plate 3 is more solid after being welded.
