Description

Technical Field

[0001] The invention belongs to the technical field of ship lock engineering, and in particular relates to an all-steel structural navigation wall. Background Art

[0002] A ship lock refers to a type of "navigation building". The existing hydraulic structures of ship locks are all concrete structures, and the navigation wall is a navigation building in the pilot channel. Most of the navigation walls of ship locks that have been built currently adopt gravity structures, and a small number of them adopt pier-slab structures, buttress structures, etc.

[0003] The structure of the ship lock is huge and has high requirements for the foundation. It is generally constructed by pouring on site. The process includes foundation trench excavation, foundation treatment, steel bar binding, formwork support, and concrete pouring. In addition, due to the limitation of concrete solidification time, after pouring one warehouse of concrete, the concrete can only be poured after it has a certain strength, which makes the overall construction period of the ship lock long, and consumes manpower and material resources, thereby increasing the cost of the ship lock construction. Cast-in-place construction of concrete structures generally requires dry land construction. Therefore, in the current ship lock construction, except for the construction of ship locks completely on the newly excavated channel on the shore, construction cofferdams are required to separate the construction site from the river to achieve dry land construction; the construction of construction cofferdams accounts for a large proportion of the investment, occupies a long construction period, and has a very large restrictive effect on the main construction. In addition, due to the inherent characteristics of cast-in-place concrete structures, it is impossible to realize the industrialized and standardized production of ship locks, and there are great limitations in construction efficiency and construction quality.

[0004] In addition, when the ship lock reaches the end of its service life or is renovated or expanded, a large amount of concrete waste will inevitably be produced, which are non-degradable pollutants.

[0005] The navigation wall in the prior art has the function of guiding ships into the lock, and most of the navigation walls also have the function of retaining soil. The navigation wall with concrete structure currently has the following problems in practical application: dry land construction is required, the construction period is long, and the cost is high; the construction quality is subject to the performance of the material itself, and it is difficult to improve significantly; it is easy to be damaged by collision and difficult to repair; because the navigation wall is distributed over a long period of time, the foundation conditions will change, and uneven settlement and horizontal displacement are prone to occur, and they cannot be repaired; the existing gravity navigation wall structure is limited by its construction materials, and the structural form is difficult to be essentially optimized, and it cannot flexibly adapt to various geological changes. In addition, the increase in the cross-sectional form of the navigation wall will increase the workload of reinforced concrete construction by multiples; after the service life expires, a large amount of waste slag will be generated, which will damage the environment. Therefore, it is a technical problem that technicians in this field need to solve urgently to provide a navigation wall with an all-steel structure that can realize water construction, can better adapt to various geological conditions, reduce construction time and reduce pollution. Summary of the invention

[0006] In order to solve the above-mentioned problems existing in the prior art, the present invention provides an all-steel structural navigation wall to solve the technical problems existing in the prior art that the navigation wall requires dry land construction, has a long construction period, generates a large amount of pollutants, is easily damaged and difficult to repair, cannot be produced in a working manner, and is difficult to achieve standardization and normalization.

[0007] The present invention is specifically implemented through the following technical solutions:

[0008] An all-steel navigation wall, which is composed of a number of structural segments connected in sequence into a straight line or arc shape, each structural segment including a wall body and a bottom plate made of steel structure;

[0009] The wall body is composed of a full-size empty box and an adjustable empty box, both of which are provided with a steel structure cover plate on the top; the height of the full-size empty box is determined according to the use requirements, and the width is adjustable; the vertical and horizontal partitions are arranged inside the full-size empty box to strengthen the overall rigidity of the structure on the one hand, and to divide the interior of the empty box into several compartments on the other hand, which is used to accurately control the amount of filling materials; the height and width of the adjustable empty box can be adjusted according to actual conditions; the vertical and horizontal partitions are arranged inside the adjustable empty box to strengthen the overall rigidity of the structure on the one hand, and to divide the interior of the empty box into several compartments on the other hand, which is used to accurately control the amount of filling materials. The bottom plate is an integral box-shaped steel structure with vertical and horizontal partitions inside, and the empty box can be filled with bulk materials or water according to actual conditions to increase its own weight, maintain stability, and increase structural rigidity.

[0010] The structural segments are independent of each other, and the structural segments cooperate with the connecting keys (grooves) of adjacent structural segments through connecting grooves (keys) to achieve lateral force transmission between the structural segments without affecting the longitudinal expansion and contraction of each structural segment.

[0011] The wall body and the bottom plate, as well as the full-size empty box and the adjustment empty box can be connected by welding or bolts to form a whole. Stiffening ribs are arranged at the front edge facing the water and at the back side between the wall body and the bottom plate to improve local stress concentration.

[0012] In summary, the present invention has the following technical effects:

[0013] All components of the all-steel navigation wall are manufactured in factories to realize the industrialized and standardized production of ship locks. The manufactured components are sent to the construction site for installation, and underwater construction can be realized, which greatly shortens the construction period of the ship lock, saves cofferdam investment, and does not produce concrete residue to reduce the generation of pollutants; the full-size empty boxes of the wall body can adjust their own weight and center of gravity by adjusting the width and the distribution of filling materials in the compartment; the empty boxes can be adjusted to adjust their own weight and center of gravity by adjusting the height, width and the distribution of filling materials in the compartment; the bottom plate can adjust its own stiffness, self-weight and center of gravity by adjusting the length, height and compartment layout; therefore, the all-steel navigation wall has good adaptability to various terrains and geological conditions, and can also be coordinated with various foundation treatment measures.

[0025] The wall is composed of a full-size empty box 3 and an adjustable empty box 4, both of which are provided with steel structure covers on the top; the height of the full-size empty box 3 is determined according to the use requirements, and the width is adjustable; the interior of the full-size empty box 3 is provided with vertical and horizontal partitions to divide the interior of the empty box into a number of compartments 16, and the compartments 16 are filled with bulk materials or water as required; the height and width of the adjustable empty box 4 can be adjusted according to actual conditions; the interior of the adjustable empty box 4 is provided with vertical and horizontal partitions to divide the interior of the empty box into a number of compartments 17, and the compartments 17 are filled with bulk materials or water as required. The bottom plate 2 is an integral box-shaped steel structure with vertical and horizontal partitions inside, and the compartments 20 can be filled with bulk materials or water according to actual conditions to increase the deadweight, maintain stability, and increase structural rigidity.

[0026] The wall body 1 and the bottom plate 2 as well as the full-size empty box 3 and the adjustment empty box 4 can be connected by welding or bolts to form a whole.

[0027] Between the wall body 1 and the bottom plate 2, a stiffening rib 5 is provided at the front side facing the water, and a stiffening rib 6 is provided at the back side facing the water to improve local stress concentration.

[0028] An all-steel navigation wall with the above structure can firstly excavate the foundation trench underwater during the construction process, and then dump stones, compact and level them underwater to form a riprap base bed; at the same time, transport the wall body and bottom plate produced in the factory to the construction site, and then further assemble them on site according to the lifting capacity; finally, select suitable lifting equipment, and gradually lift them in order from bottom to top of the structure, and at the same time fill the compartments of each part with loose materials and backfill the wall according to the calculation situation; after the assembly of each part of the wall, the filling of the compartments in the empty box, the backfilling and compaction behind the wall are completed, the main construction of the navigation wall is completed.
