Description

Technical Field

[0001] The utility model relates to the design of a ship lock hydraulic structure, and more specifically to a prefabricated cover plate empty box structure of a ship lock head. Background Art

[0002] In the traditional empty box structure of the upper and lower gates, there are many empty boxes at the upper and lower gates, and they are large in size. It is difficult to support the empty box concrete formwork, and the construction efficiency is low and the construction is difficult. The conventional practice for the construction of the upper and lower gate empty boxes is to use a full-height bracket layout for the empty box top plate, and reserve a skylight on the top surface of the empty box to facilitate the removal of the formwork inside the empty box after the concrete pouring is completed. There are many construction processes and construction safety risks for construction personnel. The dimensions of the traditional empty box structure at the gate are not uniform, making it difficult to realize the industrial digitalization of the lock structure design. At the same time, the dimensions of the construction formwork are variable, which is not conducive to the promotion of construction standardization.

[0003] In engineering, the cover is often designed according to the size of the groove, and the size of the empty box structure at the head of the ship lock is often determined according to the designer's experience. There is no unified empty box size. Therefore, in the current ship lock design, no cover is used to solve the above construction pain points. Standardizing the empty box at the head of the ship lock and integrating the design of the cover with standard size can solve the problems of low construction efficiency and high construction difficulty, and provide strong support for construction quality and engineering benefits.

[0004] Prefabricated plate structures are also found in docks, water supply and drainage trenches and other structures. Such structures are mainly used as dock panels or trench pedestrian covers. In view of the large span of the empty box structure of the ship lock and the large load of upper concrete pouring construction, such covers will be deformed or even broken, making it difficult to use them as empty box structures of the ship lock. At the same time, trench covers are mostly steel structures, which are expensive and not economical in engineering. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a prefabricated cover plate empty box structure for a ship lock, which can solve the problems of low construction efficiency, great difficulty in safety assurance and difficult digital design of the traditional empty box structure for a ship lock.

[0006] The technical solution adopted by the utility model to solve its technical problems is: constructing a prefabricated cover plate empty box structure for a ship lock head, comprising an empty box and a prefabricated cover plate group arranged on the top of the empty box; the empty box is a hollow structure, and the prefabricated cover plate group is composed of a plurality of prefabricated cover plates spliced ​​and combined.

[0007] According to the above solution, the prefabricated cover plate is a prefabricated concrete structure.

[0008] According to the above scheme, the interior of the prefabricated cover plate is provided with prefabricated cover plate longitudinal reinforcement and prefabricated cover plate transverse reinforcement, and the top of the prefabricated cover plate is provided with continuous tooth grooves.

[0009] According to the above solution, a plurality of prefabricated cover plate anchor bars are arranged on the prefabricated cover plate for connection with cast-in-place concrete.

[0010] According to the above scheme, the plane dimensions of the empty box are 4040, 5050, 6060, 7070, 8080, 9090×3600, 4600mm in length×width, and 5000, 4000×1000×250mm in length×width of the prefabricated cover plate structure, and the continuous tooth groove at the top of the prefabricated cover plate is 200×20mm in length×width.

[0011] According to the above scheme, the longitudinal reinforcement of the prefabricated cover plate adopts HRB400 with a diameter of 25 and a spacing of 100mm, the transverse reinforcement of the prefabricated cover plate adopts HRB400 with a diameter of 16 and a spacing of 140mm, the pull ring of the prefabricated cover plate adopts HPB300 with a diameter of 20, the pull ring anchor plate is a 150*260*10mm steel plate, and the anchor bar of the prefabricated cover plate is HPB300 with a diameter of 10, a spacing of 400mm and a length of 550mm.

[0012] The implementation of the hollow box structure of the prefabricated cover plate of the ship lock head of the utility model has the following beneficial effects:

[0013] 1. The common prefabricated cover plate of the utility model can be directly placed on the empty box to cast concrete to form an integral structure. For the prefabricated cover plates of the composite beam, the adjacent prefabricated cover plates can be connected into a whole through the prefabricated cover plate structure connecting ribs of the composite beam. At the same time, the prefabricated cover plates at the ends of the composite beam are cast into a whole through cast-in-place concrete steel bars, cast-in-place concrete structure connecting ribs and the gate head cast-in-place concrete, which provides different options for different forces, facilitates structural construction, and solves the problems of difficult support of the empty box concrete formwork, low construction efficiency, and great construction difficulty;

[0014] 2. The utility model provides a basis for structural construction and facilitates the application of structural construction. It solves the problem that in the traditional lock head empty box structure, the upper and lower lock head empty boxes are large in number and size, and there are difficulties in supporting the empty box concrete formwork, low construction efficiency and great construction difficulty. The size of the lock head empty box structure is unified, laying a foundation for realizing the industrial digitalization of the ship lock structure design and the standardization of construction.

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0027] like Figure 1-9 As shown, the hollow box structure of the prefabricated cover plate of the ship lock head of the utility model comprises a hollow box 1 and a prefabricated cover plate group arranged on the top of the hollow box 1; wherein the hollow box 1 is a hollow structure, and the prefabricated cover plate group is composed of a plurality of prefabricated cover plates 2 spliced ​​together. The prefabricated cover plates 2 are prefabricated concrete structures.

[0028] The plane size of the empty box 1 structure is 4040 (5050, 6060, 7070, 8080, 9090) * 3600 (4600) mm. The standard size of the empty box 1 leaves enough room for a 10mm error gap, and also provides a standard size (4000mm, 5000m) for the prefabricated cover plate 2, thereby avoiding the difficulties caused by the variety of empty box 1 sizes to the digital design and construction standardization. The prefabricated cover plate 2 is provided with a prefabricated cover plate longitudinal steel bar 3 and a prefabricated cover plate transverse steel bar 4. A plurality of prefabricated cover plate anchor bars 7 are provided on the side of the prefabricated cover plate 2 for connection with cast-in-place concrete. The structural size of the prefabricated cover plate 2 is 5000 (4000) × 1000 × 250 mm (length × width × height), and a continuous tooth groove is provided on the top of the prefabricated cover plate 2, with a size of 200 * 20. The standard size of the prefabricated cover plate 2 facilitates the large-scale use of engineering prefabrication and structures, and reduces the prefabrication cost. The length of the prefabricated cover plate 2 on each side of the upper part of the empty box 1 is 200mm. This ensures the depth of the prefabricated cover plate 2 embedded in the gate head concrete, providing a guarantee for the structural safety. The one-time pouring of concrete on the upper part of the prefabricated cover plate 2 shall not exceed 2m. The secondary pouring of the upper structure can be carried out only after the strength of the cast-in-place concrete in this area reaches 85% of the design strength. This provides a basis for structural construction and facilitates the application of structural construction.

[0029] The longitudinal reinforcement 3 of the prefabricated cover plate adopts HRB400 diameter 25 reinforcement with a spacing of 100mm, the transverse reinforcement 4 of the prefabricated cover plate adopts HRB400 diameter 16 reinforcement with a spacing of 140mm, the pull ring 5 of the prefabricated cover plate adopts HPB300 diameter 20 reinforcement, the pull ring anchor plate 6 is a 150*260*10mm steel plate, and the prefabricated cover plate anchor 7 is HPB300 diameter 10 reinforcement with a spacing of 400mm and a length of 550mm.

[0030] The prefabricated cover plate group includes an ordinary prefabricated cover plate group and a composite beam prefabricated cover plate group. When the upper structure of the prefabricated cover plate 2 is not subjected to forces other than concrete, an ordinary prefabricated cover plate group is used. When the upper part is subjected to a large external force, it is recommended to use a composite beam prefabricated cover plate group to meet the construction needs under different conditions. The main difference between the ordinary prefabricated cover plate group and the composite beam prefabricated cover plate group is that the longitudinal reinforcement 3 of the ordinary prefabricated cover plate does not extend out of the prefabricated cover plate 2 structure, and the composite beam prefabricated cover plate 2 extends out of the prefabricated cover plate 2 structure because it needs to be connected to the cast-in-place concrete. The ordinary prefabricated cover plate 2 group is as follows: a pull ring anchor plate 6 is provided on the prefabricated cover plate 2 arranged at the two ends of the top of the empty box 1, and a prefabricated cover plate pull ring 5 is fixedly provided on the pull ring anchor plate 6, thereby ensuring that the prefabricated cover plate 2 is convenient for on-site hoisting construction, while ensuring the structural strength of the prefabricated cover plate 2. The composite beam precast cover plate group is as follows: the precast cover plates 2 arranged at the two ends of the top of the empty box 1 are provided with composite beam precast cover plate structure connecting ribs 8 on the sides, and the adjacent precast cover plates 2 are connected and fixed by the composite beam precast cover plate structure connecting ribs 8 and then cast into a whole with cast-in-place concrete steel bars 9, cast-in-place concrete structure connecting ribs 10 and gate head cast-in-place concrete 11. Ordinary precast cover plates 2 can be directly placed on the empty box 1 to cast concrete to form an integral structure; composite beam precast cover plates 2 can connect adjacent precast cover plates 2 into a whole with composite beam precast cover plate 2 structure connecting ribs, and the precast cover plates 2 at the ends of the composite beams are cast into a whole with cast-in-place concrete steel bars 9, cast-in-place concrete structure connecting ribs 10 and gate head cast-in-place concrete 11.

[0031] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, which all fall within the protection of the utility model.
