The underground continuous walls 1 are located on both sides of the length direction of the foundation pit, and play a corresponding supporting role on the pit walls on both sides of the foundation pit to ensure the normal progress of the construction in the foundation pit.
[0008] In order to achieve waterproofing of the entire subway station structure, waterproof membrane 2 is pre-buried on the inner side of the lower part of each underground continuous wall 1, and the waterproof membrane 2 extends out of both ends of the length direction of the underground continuous wall 1. The waterproof membrane 2 between the underground continuous walls 1 on the same side are overlapped with each other. The waterproof membrane 2 is pre-buried in the underground continuous wall 1, which can avoid gaps between the waterproof membrane 2 and the underground continuous wall 1. The waterproof membrane 2 between the underground continuous walls 1 on the same side are overlapped with each other, which can also effectively avoid water leakage between the assembly gaps.
[0009] For the waterproof connection of the waterproof membrane 2 between the underground continuous walls 1 on both sides, the side of the waterproof membrane 2 extending out of the underground continuous wall 1 is provided with a long rod 3, which is located in the middle of the subway station and arranged along the length direction of the subway station, such as Figure 4 As shown, the long rods 3 on the corresponding underground continuous walls 1 on both sides drive the waterproof membrane 2 to be wound in a circle, and the two corresponding long rods 3 are located in the waterproof membrane 2 wound in a circle. The waterproof membrane 2 is wound in multiple layers and fixedly connected by the long rods, so as to realize the waterproof connection of the waterproof membrane 2 between the underground continuous walls 1 on both sides, and prevent groundwater from entering the subway station from the joints of the waterproof membrane 2. At the same time, the long rods 3 drive the winding of the corresponding waterproof membrane 2, and will not affect the overlap of the waterproof membrane 2 at the bottom of the underground continuous wall 1 on the same side, thereby realizing the effective waterproof performance of the overall structure when the ground-connected wall and the waterproof membrane 2 are laid.
[0010] A fine stone concrete layer 4 is provided on the upper side of the waterproofing membrane 2, a station floor 5 is provided on the fine stone concrete layer 4, first side walls 6 are provided on both sides of the station floor 5, a horizontally arranged station middle plate 7 is connected to the first side wall 6, second side walls 8 are provided on both sides of the station middle plate 7, and a horizontally arranged station top plate 9 is connected to the second side wall 8. The station floor 5, the first side wall 6, the station middle plate 7, the second side wall 8 and the station top plate 9 together constitute the basic structure of the subway station, and the above-mentioned components can be made of reinforced concrete building composite materials to ensure the strength of the overall facility.
[0011] In order to provide necessary support for the station middle plate 7 and the station top plate 9 between the side walls, a plurality of first columns 10 arranged side by side are installed between the station middle plate 7 and the station bottom plate 5, and a first longitudinal beam 11 is provided on each of the first columns 10 in the same straight line position. A plurality of second columns 12 arranged side by side are installed between the station top plate 9 and the station middle plate 7, and a second longitudinal beam 13 is provided on each of the second columns 12 in the same straight line position. The station top plate 9 is supported by the second longitudinal beam 13, and is supported one by one in the length direction by the second columns 12, and the station middle plate 7 is supported by the first longitudinal beam 11, and is supported one by one in the length direction by the first columns 10, thereby realizing step-by-step support of multi-story buildings in the subway station, and ensuring the stability and firmness of the structural facilities in the subway station.
[0012] The first side wall 6 and the second side wall 8 are both vertically arranged on the inner side of the underground continuous wall 1. While achieving side support and constructing an installation foundation, they can also further prevent groundwater from entering the internal facilities of the subway station through effective waterproofing at the bottom of the underground continuous wall 1.
[0013] In order to ensure the strength of the upper part of the underground continuous wall 1, a cap beam 14 is provided on the inner side of the upper end of the underground continuous wall 1. Figure 5 As shown, the outer periphery of the crown beam 14 is provided with a first water stop strip 15, and the two sides of the station roof 9 are provided with bosses 16 that match the crown beam 14, and the second side wall 8 is located at the bottom of the crown beam 14. The first water stop strip 15 is provided to avoid water leakage at the structural connection. The crown beam 14 can support, distribute and transfer the load of the upper structure of the ground connection wall, form necessary support for the station roof 9, and transfer the load to the lower structure. At the same time, it also provides a reference for the construction and installation of the station roof 9. It does not need to be disassembled separately in the later stage and can be used as a part of the subway station structure.
[0014] Furthermore, in order to avoid water leakage at the connection position between the underground continuous wall 1, the station floor 5 and the first side wall 6, as shown in FIG. Figure 6 As shown, an L-shaped plate 17 is pre-buried inside the lower end of the underground continuous wall 1, the first side wall 6 is located on the upper side of the L-shaped plate 17, grooves 18 matching the L-shaped plate 17 are provided on both sides of the station floor 5, and a second water stop strip 19 is provided between the first side wall 6 and the L-shaped plate 17. The provision of the L-shaped plate 17 can improve the integrity of the connection between the first side wall 6 and the station floor 5, providing a reference for the construction and installation of each other, and the provision of the second water stop strip 19 can effectively avoid water leakage at the connection position.
[0015] Furthermore, in order to avoid water leakage at the connection position between the upper part of the first side wall 6 and the bottom of the second side wall 8, a T-shaped plate 20 is pre-buried on the inner side of the underground continuous wall 1, the first side wall 6 is located at the lower side of the T-shaped plate 20, and the second side wall 8 is located at the upper side of the T-shaped plate 20, and a third water stop strip 21 is provided between the T-shaped plate 20 and the side wall.
[0016] In order to improve the connection strength between the first side wall 6, the second side wall 8 and the station middle plate 7, as Figure 7 As shown, an embedded rod 22 is provided between the T-shaped plate 20 and the station middle plate 7, a first protrusion 23 protruding upward is provided on the top of the first side wall 6, a second protrusion 24 protruding downward is provided on the bottom of the second side wall 8, and a slot matching the first protrusion 23 and the second protrusion 24 is provided on the lower side and the upper side of the station middle plate 7. The provision of the embedded rod 22 can enhance the connection strength between the station middle plate 7 and the ground connection walls on both sides, and the provision of the protrusions and matching slots on both sides can also provide an installation reference for the stable connection between the first side wall 6, the second side wall 8 and the station middle plate 7, thereby improving the stability of the overall structure.
[0017] Furthermore, in order to enhance the supporting strength of the first side wall 6 on the station middle plate 7 and enhance the supporting strength of the second side wall 8 on the station top plate 9, diagonal bracing mechanisms are provided between the station middle plate 7 and the first side walls 6 on both sides and between the station top plate 9 and the second side walls 8 on both sides.
[0018] like Figure 8-10 As shown, the diagonal bracing mechanism includes a hidden beam 25 arranged in the first side wall 6 and the second side wall 8, and a plurality of support plates 26 are arranged on the hidden beam 25. The support plate 26 is located on the inner side of the side wall, wherein the hidden beam 25 is located inside the side wall, which can effectively enhance the connection strength between the diagonal bracing mechanism and the side wall. The hidden beam 25 which does not protrude from the side wall can play a corresponding connecting role while avoiding interference with the space inside the station.
[0019] In order to realize the supporting connection between the station middle plate 7 and the station top plate 9, hinge seats 27 corresponding to the support plates 26 are arranged at the bottom of both sides of the station middle plate 7 and the station top plate 9, and swingable support rods 28 are installed on the hinge seats 27. The bottom of each support rod 28 is provided with a connecting plate 29, and the connecting plate 29 can realize detachable fixed connection with the corresponding support plate 26. In order to facilitate the adjustment of the connection angle between the support rod 28 between the side wall and the middle plate and the top plate, a long groove 30 is provided on the connecting plate 29, and a screw hole is provided on the support plate 26. A connecting bolt 31 matching the screw hole is installed in the long groove 30. By adjusting the position of the connecting bolt 31 in the long groove 30, the connecting plate 29 can be fixedly connected at different positions on the support plate 26, thereby adjusting the rotation angle of the support rod 28 relative to the hinge seat 27, realizing the supporting angle position of the support rod 28 between the side wall and the station middle plate 7 and the station top plate 9, and providing the necessary supporting performance for the structural connection in the station.
[0020] Furthermore, in order to improve the connection strength and support performance of the first column 10 between the station floor 5 and the station middle plate 7, a first embedded rib 32 is provided at the position corresponding to the station floor 5 and the first column 10, and a second embedded rib 33 is provided at the position corresponding to the first longitudinal beam 11 and the station middle plate 7. In order to improve the connection strength and support performance of the second column 12 between the station middle plate 7 and the station top plate 9, a third embedded rib 34 is provided at the position corresponding to the station middle plate 7 and the second column 12, and a fourth embedded rib 35 is provided at the position corresponding to the second longitudinal beam 13 and the station top plate 9. The arrangement of the above embedded ribs can connect the station floor 5, the station middle plate 7 and the station top plate 9 into a whole, improve the connection and support performance of each plate layer structure in the vertical direction, enhance the tensile and compressive performance between the structures in the station, and ensure the strength between the floors in the station.
[0021] Furthermore, to ensure the waterproof performance of the waterproofing membranes 2 between adjacent underground continuous walls, the overlapping waterproofing membranes 2 of the underground continuous walls 1 on the same side are sealed with cement-based penetrating crystalline waterproof coatings. To effectively prevent groundwater from entering the station from the gaps between the membranes, the overlapping length between adjacent waterproofing membranes 2 is 15-30cm. The longer overlapping length between adjacent membranes can effectively increase the overlapping area between the membranes, thereby effectively preventing groundwater from entering the station from the gaps between the waterproofing membranes 2.
[0022] Furthermore, in order to ensure the connection sealing performance of the waterproof membrane 2 between the ground-connected walls on both sides, the diameter of the long rod 3 is 1-3 cm, and at least three layers of waterproof membrane 2 are wrapped around the periphery of the two long rods 3 .
[0023] Furthermore, in order to facilitate the construction of the overall structure of the station, the thickness of the fine stone concrete layer 4 is 50-100 mm. When ensuring the waterproof performance of the roll material, the thickness of the waterproof roll material 2 is preferably 2.5-5 mm.
[0024] Furthermore, in order to realize the pre-embedded installation of the waterproof membrane 2 in the underground continuous wall 1, as Fig.11 As shown, the end of the waterproof membrane 2 extending into the continuous wall can be fixedly connected to the steel plate. The steel plate is welded and fixed to the steel cage, and then concrete is poured to form the underground continuous wall 1. At the same time, the end of the waterproof membrane 2 is pre-buried in the underground continuous wall 1, thereby effectively avoiding leakage from the joints at the bottom of the station and improving the waterproof performance of the bottom of the station.
[0025] Furthermore, if Fig.12 As shown, the waterproof station structure system may not have side walls inside. The station floor 5, station middle plate 7 and station roof 9 are directly set between the underground continuous walls 1 on both sides, and the waterproof membrane 2 pre-buried in the underground continuous wall 1 blocks the leakage seam between the ground wall and the floor. The side wall structure is eliminated, which can save a lot of cost while maintaining the strength of the station structure system and improve the operation efficiency. Due to the dense waterproof performance of the ground-connected wall structure itself, the station structure system can directly use the waterproof advantage of the ground-connected wall after eliminating the side wall. Waterproof components can be pre-buried at the position where the roof and the ground-connected wall are connected to further prevent water from entering the station from the gaps on both sides of the roof.
