Description

Technical Field

[0001] The utility model relates to the technical field of hydropower engineering sluice piers, in particular to a sluice pier. Background Art

[0002] In the field of water conservancy projects, especially in the design and construction of spillways, electromechanical equipment is often integrated inside the piers to operate the opening and closing of the gates. The protection of these electromechanical equipment is crucial to the safe operation of the entire water conservancy project. However, existing spillway piers are often designed as closed structures. For example, the Chinese patent document with publication number CN210507336U discloses a pier in which an inspection gate is suspended within an inspection gate slot. The electromechanical equipment is usually installed in an equipment installation chamber inside the pier and protected by a top cover plate. During the installation of equipment inside existing piers, it is often necessary to simultaneously construct the cover plate. However, the cover plate is generally a monolithic concrete structure that needs to be cast by setting up a formwork support system within the equipment installation chamber. In this way, the formwork support system will occupy the limited internal space of the pier, affecting the installation progress of the electromechanical equipment. In addition, the construction efficiency is low, which is not conducive to ensuring the smooth progress of the construction progress. In addition, the formwork support system needs to be dismantled, and the dismantling work usually needs to be carried out at high altitude, which not only affects construction efficiency but also poses a major safety hazard. The risks of working at height not only threaten the safety of construction workers, but also may cause damage to the electromechanical equipment inside the pier if components of the formwork support system fall, thereby affecting the safe operation of the entire water conservancy project.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] The sluice pier disclosed in the utility model has a cover plate located on top of the pier body, comprising a prefabricated layer and a cast layer located on the prefabricated layer.

[0036] Figures 1 to 15 An embodiment of a sluice pier of the present invention is shown. The sluice pier of this embodiment includes a pier body 1. An equipment installation chamber 2 is provided in the pier body 1. An opening is provided on the top of the equipment installation chamber 2. A cover plate 3 is provided on the top of the pier body 1 to seal the opening of the equipment installation chamber 2. The cover plate 3 includes a prefabricated layer 31 and a casting layer 32. The prefabricated layer 31 includes a plurality of prefabricated panels 311 spliced in sequence. The prefabricated panels 311 are erected on the pier body 1 and span the top of the equipment installation chamber 2. The prefabricated panels 311 are pre-embedded with load-bearing beams 4 along the length direction. Both ends of the load-bearing beams 4 extend out of the prefabricated panels 311 to form a connecting portion 40. The casting layer 32 is covered on the prefabricated layer 31 and supported on each load-bearing beam 4. Both sides of the casting layer 32 are supported on the pier body 1. The connecting portion 40 is connected to the casting layer 32.

[0037] In the sluice pier of this embodiment, the cover plate 3 provided on the top of the pier body 1 includes a prefabricated layer 31 and a cast layer 32 provided on the prefabricated layer 31. The prefabricated layer 31 can be divided into multiple prefabricated panels 311 according to the shape of the top of the pier body 1. These panels are prefabricated and numbered separately. After prefabrication, they are hoisted to the top of the pier body 1 in sequence according to their numbers, so that each prefabricated panel 311 spans the top of the equipment installation chamber 2 and is erected on the pier body 1, providing a stable construction platform for the subsequent construction of the cast layer 32. After construction is completed, the cast layer 32 will form an integral part with the prefabricated layer 31, without the need to remove the prefabricated layer 31. During the construction of the entire cover plate 3, there is no need to set up a formwork support system in the equipment installation chamber 2, and the space of the equipment installation chamber 2 is not occupied. The installation of the electromechanical equipment and the construction of the casting layer 32 can be carried out simultaneously without affecting each other and the installation progress of the electromechanical equipment, thereby improving construction efficiency and ensuring the smooth progress of the construction progress. At the same time, it also avoids the support components from falling when the support system is dismantled, thereby damaging the electromechanical equipment or causing casualties, thereby improving construction safety; each prefabricated panel 311 is buried with a load-bearing beam 4 along the length direction, and both ends of the load-bearing beam 4 extend out of the prefabricated panel 311 to form a connecting portion 40, which is connected to the casting layer 32, which is conducive to improving the connection strength between the casting layer 32 and the prefabricated layer 31 after the construction is completed. In addition, during the hoisting process of the prefabricated panel 311 or the construction process of the casting layer 32, if the prefabricated panel 311 moves and its end is separated from the pier body 1, the connecting portion 40 can also be supported on the top of the pier body 1, which is conducive to preventing the prefabricated panel 311 from falling and damaging the electromechanical equipment or causing casualties, and has high safety. The sluice pier and the cover plate 3 of this embodiment will not affect the installation of the electromechanical equipment in the equipment installation chamber 2 during the construction process, and the construction efficiency and construction safety are high.

Connecting rods 42 are located within the prefabricated panel 311. This reduces the weight of the load-bearing beam 4 while maintaining its structural strength. Of course, in other embodiments, depending on the size of the prefabricated panel 311 and actual construction needs, a single or multiple load-bearing rods 41 may be provided, with connecting rods 42 connecting adjacent load-bearing rods 41. The details will not be repeated here.

[0039] As a preferred embodiment, the load-bearing rod 41 is an I-beam (see Figure 7 ), the connecting rod 42 is an angle steel (see Figure 5), the ends of the connecting rod 42 are respectively welded to the webs of the two load-bearing beams 4. I-beams and angle steel are easily available on site and have high structural strength. The flanges of the I-beams increase the contact area with the precast panels 311, improving the connection strength between them and the precast panels 311, thereby enhancing the ability of the load-bearing beams 4 and precast panels 311 to jointly bear the weight of the concrete cast layer 32.

[0040] Furthermore, in this embodiment, a plurality of first stiffening plates 411 are provided on both sides of the load-bearing rod 41 along the length direction (see Figure 2 、 Figure 5 and Figure 8 This can effectively enhance the rigidity and strength of the load-bearing rod 41, reduce the deflection and deformation of the load-bearing rod 41 when subjected to force, and help enhance stability during long-term use. Specifically, the side surfaces of the first stiffening plates 411 are welded to the web of the load-bearing rod 41, the top surfaces of the first stiffening plates 411 are welded to the upper flange of the load-bearing rod 41, and the bottom surfaces of the first stiffening plates 411 are welded to the lower flange of the load-bearing rod 41.

The structural strength of the connection part 40 is enhanced, the connection area between the connection part 40 and the casting layer 32 is increased, and the connection strength between the load-bearing beam 4 and the casting layer 32 is improved. Specifically, a plurality of second stiffening plates 401 are spaced apart along the length direction of the connection part 40, the side surfaces of the second stiffening plates 401 are welded to the web of the load-bearing rod 41, the top surfaces of the second stiffening plates 401 are welded to the upper flange of the load-bearing rod 41, the bottom surfaces of the second stiffening plates 401 are welded to the lower flange of the load-bearing rod 41, the side surfaces of the third stiffening plates 402 are welded to the web of the load-bearing rod 41, and the two ends of the third stiffening plate 402 are respectively welded to the two adjacent second stiffening plates 401 located on the same connection part 40. Preferably, the second stiffening plates 401 on both sides of the connection part 40 are symmetrically arranged, and the third stiffening plates 402 on both sides of the connection part 40 are symmetrically arranged.

After the precast panel 311 is hoisted onto the pier body 1 and its position is determined, the first limiting posts 11 and the second limiting posts 12 limit the precast panel 311 to prevent it from shifting.

[0043] Furthermore, in this embodiment, the load-bearing beam 4 is provided with a lifting lug 5 (see Figure 9 ) to facilitate the lifting of prefabricated panels 311.

[0044] Furthermore, in this embodiment, the bottom end of the lifting lug 5 is fixedly connected to the load-bearing beam 4 and embedded in the precast plate 311, and the top of the lifting lug 5 is formed with a lifting portion 51 and embedded in the casting layer 32 (see Figure 2 The bottom end of the lifting lug 5 is embedded in the precast panel 311, further enhancing the structural strength of the precast panel 311 while also strengthening the connection between the lifting lug 5 and the load-bearing beam 4, thereby preventing the lifting lug 5 from falling off during the installation of the precast panel 311. The lifting portion 51 is embedded in the casting layer 32, thereby strengthening the connection between the precast layer 31 and the casting layer 32.

[0045] See Figure 2 、 Figure 4 、 Figure 5 、 Figure 11 and Figure 13 As a preferred embodiment, the lifting lugs 5 are provided on the load-bearing rods 41. The lifting lugs 5 are symmetrically provided on the front and rear sides of each load-bearing rod 41.

After the pier body 1 is constructed, the electromechanical equipment is installed in the equipment installation chamber 2 inside the pier body 1. After the precast panels 311 are constructed, they are hoisted to the designated positions on the pier body 1 in sequence. After each precast panel 311 is hoisted into place, concrete is poured on the precast panel 311 to form a casting layer 32, so that the casting layer 32 covers the precast layer 31. After the construction of the casting layer 32 and the installation of the electromechanical equipment are completed, the construction of the sluice pier is completed. It should be noted that during the hoisting of the precast panels 311 and the construction of the casting layer 32, the installation of the electromechanical equipment is carried out simultaneously.
