Description

Technical Field

[0001] This utility model relates to the technical field of floating slabs, and in particular to a prefabricated spring floating slab structure used in section-built pump house areas. Background Technology

[0002] In existing rail transit designs, the combination of in-station pump houses and precast floating slab track is generally avoided as much as possible. However, with increasingly complex rail transit line conditions and stricter environmental requirements, the overlap between these two approaches is gradually increasing. In-station pump houses and precast floating slab track are both widely used in urban rail transit systems.

[0003] Existing precast floating slabs typically have holes drilled at the ends (both longitudinal ends of the slab), which affects the installation of shear hinges between slabs and is not conducive to the installation and maintenance of submersible pumps or the external connection of submersible pump cables, thus limiting the functionality of floating slab track beds. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of the prior art by providing a prefabricated spring floating slab structure for use in sections with built-in pump stations. This structure consists of prefabricated floating slabs and spring vibration isolators. The prefabricated floating slabs are installed on the base via the spring vibration isolators. A pre-drilled hole is provided at the center of the prefabricated floating slab, and pre-drilled grooves communicating with the pre-drilled hole are provided on both transverse sides of the center of the prefabricated floating slab. These grooves are used to place the pumping pipes and cables of the submersible pump. Shear hinge sleeves for fixing shear hinges are provided on both longitudinal sides of the prefabricated floating slabs. This not only does not affect the installation and connection of shear hinges between slabs, ensuring the deformation coordination and stability between the longitudinal slabs of the floating slab track bed, but also facilitates the installation and maintenance of the submersible pump and the external connection of the submersible pump cables.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A prefabricated spring floating slab structure for use in a section-integrated pumping station includes a prefabricated floating slab and spring vibration isolators. The prefabricated floating slab is installed on a base via the spring vibration isolators. The prefabricated floating slab has a rectangular planar structure and an inverted trapezoidal cross-section. A pre-drilled mounting hole is provided at the center of the prefabricated floating slab. A water storage tank is provided in the middle of the base, and a submersible pump is installed in the water storage tank. The location of the submersible pump corresponds to the location of the pre-drilled mounting hole. Pre-drilled mounting slots communicating with the pre-drilled mounting hole are provided on both transverse sides of the center of the prefabricated floating slab. The pre-drilled mounting slots are used to place the pump's suction pipe and cable. Shear hinge sleeves for fixing shear hinges are provided on both longitudinal sides of the prefabricated floating slab.

[0007] The prefabricated floating slab is provided with embedded sleeves on both sides of the lateral direction. The embedded sleeves serve as lifting holes or fine adjustment holes.

[0008] Both sides of the prefabricated floating slab are connected to the base via sealing strips.

[0009] The top of the installation reserved hole is provided with a tongue and groove, and a cover plate for sealing the installation reserved hole is installed on the tongue and groove.

[0010] The top of the precast floating slab is fixed with steel rails by fasteners.

[0011] The advantages of this utility model are:

[0012] 1. It fills the gap in prefabricated floating slab track beds in areas with built-in pump stations, and has advantages such as improving the quality of floating slab track beds, shortening the construction period, and improving track laying accuracy;

[0013] 2. The professional requirements for interfaces such as section structure, water supply and drainage, power and lighting have been fully considered. The installation and maintenance of submersible pumps, cables, etc. are convenient. After the installation of cables, covers, etc., the track bed surface is clean and flat, and does not affect the emergency evacuation function of the track bed surface.

[0014] 3. The main external dimensions are based on the commonly used prefabricated floating slab design, which does not require additional mold opening and is economical;

[0015] 4. No holes are required at the ends of the precast floating slabs, which does not affect the shear hinge installation connection between the slabs and ensures the deformation coordination and stability between the longitudinal slabs of the floating slab track bed.

[0021] 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:

[0022] Example: Figures 1-3 As shown, this embodiment relates to a prefabricated spring floating slab structure used in a section-built pumping station area. The structure mainly includes a prefabricated floating slab 1 and spring vibration isolators 2. The prefabricated floating slab 1 is installed on a base 3 through the spring vibration isolators 2, with a gap 17 between the prefabricated floating slab 1 and the base 3. A steel rail 15 is fixed to the top of the prefabricated floating slab 1 through fasteners 14. The spring vibration isolators 2 are located between two adjacent fasteners 14. In this embodiment, the length of the prefabricated floating slab 1 is 3600~6000mm, the width is 2700~2900mm, and the height is 320~370mm. The spring vibration isolators 2 are installed inside the vibration isolator outer sleeve of the prefabricated floating slab 1. Four spring vibration isolators 2 and six fasteners 14 are provided on each side of the prefabricated floating slab 1 in the transverse direction.

[0023] The prefabricated floating slab 1 has a rectangular planar structure and an inverted trapezoidal cross-section. The slab body is chamfered at all four corners to reduce impacts and enhance aesthetics. A pre-drilled mounting hole 4 is provided at the center of the prefabricated floating slab 1. In this embodiment, the planar dimensions of the mounting hole 4 are 800*800mm. A tongue-and-groove joint 12 is provided at the top of the mounting hole 4, and a cover plate 13 (using a stainless steel grating cover plate) is installed on the tongue-and-groove joint 12 to seal the mounting hole 4. A water storage tank 6 is provided in the middle of the base 3, and a submersible pump 7 is installed in the water storage tank 6. The position of the submersible pump 7 corresponds to the position of the installation reserved hole 4. On both sides of the center of the prefabricated floating plate 1, there are installation reserved slots 5 that communicate with the installation reserved hole 4. In this embodiment, the cross-sectional size of the installation reserved slot 5 is generally no greater than 100*100mm. The installation reserved slot 5 is used to place the water pump pipe 8 and cable of the submersible pump 7. The water storage tank 6 can also place lighting equipment. The installation reserved slot 5 can also be used to place the cable of the lighting equipment. A tongue and groove joint 12 can also be provided on the top of the installation reserved slot 5, and a cover plate 13 for closing the installation reserved slot 5 is installed on the tongue and groove joint 12. The cover plate 13 is installed on the installation reserved hole 4 and the installation reserved slot 5 to take into account the longitudinal evacuation safety of the track bed surface and the convenience of track inspection. Both sides of the prefabricated floating slab 1 are connected to the base 3 by sealing strips 11. The sealing strips 11 can prevent water or foreign objects from entering the gap between the prefabricated floating slab 1 and the base 3, and are used to protect the spring vibration isolator 2.

[0024] like Figures 1-2As shown, both sides of the precast floating slab 1 are provided with shear hinge sleeves 9 (with internal threads) for fixing shear hinges. The shear hinges are fixed by the cooperation of bolt structure and shear hinge sleeves 9. That is, the precast floating slab 1 can be longitudinally connected with each other and with the existing floating slab 16 through shear hinges. In this embodiment, each longitudinal side of the prefabricated floating slab 1 is provided with four sets of shear hinge sleeves 9, and each set of shear hinge sleeves 9 includes six shear hinge sleeves 9. The shear hinge includes two fixed seats, two sleeves and a shear bar. The two sleeves are respectively installed on the two fixed seats and are connected to each other by the shear bar. The two ends of the shear bar are respectively installed in the two sleeves and the shear bar can move to a certain extent in the sleeves. The two fixed seats are respectively installed on the two prefabricated floating slabs 1 (or one prefabricated floating slab 1 and one existing floating slab 16). The fixed seats are fixed on the prefabricated floating slab 1 (or the existing floating slab 16) by the cooperation of the bolt structure and the shear hinge sleeves 9.

[0025] Both sides of the precast floating slab 1 are provided with embedded sleeves 10 (with internal threads), which can be used as lifting holes or fine-tuning holes. When the precast floating slab 1 is lifted, the embedded sleeves 10 can be connected to the lifting equipment (threaded fit); when the lateral position of the precast floating slab 1 is fine-tuned, the embedded sleeves 10 can be connected to the lateral position fine-tuning device (threaded fit). In this embodiment, each side of the precast floating slab 1 is provided with two sets of embedded sleeves 10, and each set of embedded sleeves 10 includes two embedded sleeves 10.

[0026] In addition, the positions of the installation reserved holes 4, installation reserved grooves 5 and embedded sleeves 10 can be determined by adopting structural reinforcing bars and spiral bars according to the overall stress characteristics of the floating slab track bed.

[0027] The beneficial technical effects of this embodiment are as follows:

[0028] 1. It fills the gap in prefabricated floating slab track beds in areas with built-in pump stations, and has advantages such as improving the quality of floating slab track beds, shortening the construction period, and improving track laying accuracy;

[0029] 2. The professional requirements for interfaces such as section structure, water supply and drainage, power and lighting have been fully considered. The installation and maintenance of submersible pumps, cables, etc. are convenient. After the installation of cables, covers, etc., the track bed surface is clean and flat, and does not affect the emergency evacuation function of the track bed surface.

[0030] 3. The main external dimensions are based on the commonly used prefabricated floating slab design, which does not require additional mold opening and is economical;

[0031] 4. No holes are required at the ends of the precast floating slabs, which does not affect the shear hinge installation connection between the slabs and ensures the deformation coordination and stability between the longitudinal slabs of the floating slab track bed.

[0032] 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.
