Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit station renovation technology, and in particular to a water-blocking structure for the opening under the train in an elevated urban rail transit station. Background Technology
[0002] Due to the addition of a new rail transit line within the existing station, an opening needs to be made in the center of the existing station floor slab to separate it from the newly built bridge piers (with a spacing of 200mm), meeting the design principle of "separation of construction and bridge." The mezzanine level beneath the platform is near the pier cap level, also requiring an opening. Currently, trains enter the station at approximately 40km / h. In rainy weather, rainwater will inevitably be brought into the station, flowing down the edges of the openings and affecting the use of the concourse and other rooms. Summary of the Invention
[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a water-blocking structure for the underpass of trains in elevated urban rail transit stations. By setting different water-blocking structures along the underpass in different directions, targeted water blocking can be achieved.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A water-retaining structure for a tunnel opening under a train in an elevated urban rail transit station, the tunnel opening being located at the existing station floor slab, with a newly constructed bridge pier at the location of the tunnel opening, characterized in that: a tunnel-side water-retaining structure is provided around the tunnel opening, the tunnel-side water-retaining structure including a first tunnel-side water-retaining structure and a second tunnel-side water-retaining structure, wherein the first tunnel-side water-retaining structure is provided on both sides of the existing station floor slab along the track direction, and the second tunnel-side water-retaining structure is provided on both sides of the existing station floor slab perpendicular to the track direction;
[0006] The first tunnel-side water-blocking structure includes an upward-turning retaining body that stands upright on the side end of the existing station floor slab near the tunnel entrance;
[0007] The second tunnel-side water-blocking structure includes an upward-turning barrier and an inclined barrier that stand upright on the side of the existing station floor slab near the tunnel entrance. The inclined barrier is located on top of the upward-turning barrier and extends toward the side of the newly built bridge pier.
[0008] A stainless steel plate is installed on the inclined retaining body, and the stainless steel plate is pressed tightly against the edge of the pier cap of the newly built bridge column pier.
[0009] Bolts are pre-embedded in the inclined stop, and the bolts form a detachable connection and fixation with the stainless steel plate.
[0010] The inclined stop is arranged at an upward 45° angle.
[0011] The height of the upward-turning retaining body of the first tunnel side water-blocking structure is the same as that of the upward-turning retaining body of the second tunnel side water-blocking structure.
[0012] The advantages of this utility model are: it can achieve a water-blocking effect, prevent water from entering, and avoid water accumulation; the structure is simple and reasonable, the construction is convenient, and it is suitable for promotion. Attached Figure Description

[0017] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:
[0018] like Figure 1-4 As shown in the figure, 1-13 represent: 1. New platform, 2. Platform mezzanine, 3. Station hall, 4. Water-retaining structure at the first tunnel edge, 5. Water-retaining structure at the second tunnel edge, 6. Upward-turning retaining body, 7. Upward-turning retaining body, 8. Inclined retaining body, 9. Pier cap edge, 10. Detachable stainless steel plate, 11. Bolt, 12. Newly built bridge pier, 13. Opening.
[0019] Example: Figures 1 to 4 As shown, in this embodiment, the water-blocking structure at the underpass of the train in the elevated station of urban rail transit is used to block water between the newly built bridge piers 12 of the new line and the floor slab of the existing station structure. Figure 1 As shown, the opening 13 is located at the existing station floor slab, and its size is slightly larger than the size of the pier cap of the newly built bridge pier 12. The opening 13 is used for the newly built bridge pier 12 to pass through.
[0020] Water-retaining structures are installed around the opening 13 in different directions. For example... Figure 2 As shown, Figure 2 The arrows indicate the direction of train travel, i.e., the direction of the railway line. The tunnel-side water-retaining structure includes a first tunnel-side water-retaining structure 4 and a second tunnel-side water-retaining structure 5. The first tunnel-side water-retaining structure 4 is installed on both sides of the existing station floor slab along the railway line direction, and the second tunnel-side water-retaining structure 5 is installed on both sides of the existing station floor slab perpendicular to the railway line direction.
[0021] like Figure 3As shown, the first tunnel-side water-blocking structure 4 includes an upward-turning baffle 5 erected on the side end of the existing station floor slab near the tunnel opening. In this embodiment, the first tunnel-side water-blocking structure 4 is a reinforced concrete water-blocking structure; in use, since the direction of rainwater is the same as the direction of train travel, the water-blocking requirement is reduced by setting the upward-turning baffle 5 along the track direction, preventing rainwater in this direction from entering the station hall level 3, and construction is convenient.
[0022] like Figure 4 As shown, the second tunnel-side water-blocking structure 5 includes an upward-turning baffle 7 and an inclined baffle 8, which are erected on the side of the existing station floor slab near the tunnel opening. The inclined baffle 8 is located on top of the upward-turning baffle 7 and extends upwards at a 45° angle towards the pier cap edge 9 of the newly constructed bridge pier 12. A removable stainless steel plate 10 is installed on the inclined baffle 8, which presses tightly against the pier cap edge 9 of the newly constructed bridge pier 12, eliminating gaps between the platform underpass 2 and the pier cap edge 9, preventing rainwater from further flowing into the concourse level 3. The inclined surfaces of the removable stainless steel plate 10 and the inclined baffle 8 facilitate rainwater falling into the platform underpass 2, preventing water accumulation. Waterproofing measures are generally installed in the platform underpass 2, so rainwater can be blocked or collected and discharged therefrom. During use, bolts 11 are pre-embedded in the inclined baffle 8, forming a detachable connection with the removable stainless steel plate 10, facilitating the replacement of the removable stainless steel plate 10.
[0023] In this embodiment, the height of the upturned baffle 6 of the first hole side water-blocking structure 4 and the upturned baffle 7 of the second hole side water-blocking structure 5 are consistent, ensuring the consistency of the water-blocking height.
[0024] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
