Description

Technical Field

[0001] This invention relates to the field of ship locks, and more specifically to a detachable ship lock chamber structure and method. Background Technology

[0002] Ship locks are crucial hydraulic structures for overcoming concentrated water level differences in waterways and ensuring ship navigation. With the development of shipping, the capacity of many early-built ship locks has become insufficient, necessitating expansion. Traditional expansion methods either involve constructing a second-line ship lock on the side (large land area and high investment) or undertaking complex permanent structural modifications to the original lock (long construction period and disruption to navigation). Neither of these methods allows for rapid, low-interference construction.

[0003] On the other hand, traditional lock chambers are mostly reinforced concrete cast-in-place structures, which have long construction cycles and are permanent structures that cannot be adjusted or disassembled once completed. Although prefabricated technology has been applied to locks, using prefabricated sidewalls and other components, existing prefabricated structures are mostly formed as a whole through cast-in-place wet joints or high-strength permanent connectors. They do not have the conditions for disassembly after completion or component reuse, nor can they be easily adjusted in terms of elevation or attitude according to settlement after installation.

[0004] Therefore, we propose a detachable lock chamber structure and method. Summary of the Invention

[0005] To address the aforementioned shortcomings of the prior art, this invention provides a detachable lock chamber structure and method.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: A detachable lock chamber structure includes: The load-bearing components are installed on the foundation to bear the vertical water pressure in the gate chamber and to prevent water in the gate chamber from seeping into the foundation. Side load components are located on both sides of the load-bearing components to bear the horizontal water pressure inside the gate chamber and to prevent water from flowing out of the gate chamber from the side. The side wall support assembly is detachably mounted on the side load assembly via a pin structure, thereby increasing the height of the side load assembly.

[0007] This detachable sidewall support assembly allows for modular installation and removal, and the components can be reused in other similar projects. The sidewall support assembly can be utilized to quickly assemble new lock chambers for expansion, enabling rapid expansion with minimal impact on navigation.

[0008] Further defined, the load-bearing components include a load-bearing base plate, bottom piles, a support frame, node connection blocks, and interlocking blocks; the bottom piles are arranged in a rectangular array and are all vertically fixed on the horizontal foundation; the load-bearing base plate is horizontally fixed on the bottom piles; the support frame includes several crisscrossing connecting beams that divide the support frame into several rectangular frames; the node connection blocks are cast-in-place at the intersections of the connecting beams; and the interlocking blocks are located within the several rectangular frames.

[0009] By casting node connection blocks at the intersection of the support frame, the structure of the support frame can be made more robust, and by setting interlocking blocks within the rectangular frame of the support frame, a permeable, stable, and water-resistant flexible protective surface can be formed.

[0010] Further defined, the side load assembly includes a hanging plate, a bearing plate, inner piles, and outer piles; the inner piles and outer piles are arranged in a rectangular array on the foundation on both sides of the bearing base plate, with the inner piles located on the side closer to the bearing base plate; the bearing plate is horizontally fixed on the inner piles and outer piles; the hanging plate is vertically arranged on both sides of the bearing base plate; the top of the hanging plate is fixedly connected to the bearing plate, and the bottom is fixedly connected to the side plate of the bearing base plate; the outer wall of the hanging plate is attached to the periphery of the inner piles; and the connection between the hanging plate and the bearing base plate and the bearing plate is sealed and waterproofed.

[0011] Further defining the side wall support assembly, it includes a side wall base plate, a side wall panel, and a mounting plate; the base plate is vertically spaced with several positioning mortises, and the bottom surface of the side wall base plate is provided with several positioning tenons corresponding to the positioning mortises. The side wall base plate is fixed to the base plate by the positioning tenons and positioning mortises. The side wall panel is vertically located inside the side wall base plate and its bottom end is also located on the base plate. The mounting plate is L-shaped, and its vertical surface is fixedly connected to the side wall panel by bolts, and its horizontal surface is fixedly connected to the side wall base plate by bolts.

[0012] This method of fixing the support plate and side wall bottom plate with positioning tenons and positioning mortises is simple in structure and makes it easier to disassemble and assemble.

[0013] Further specified, seepage prevention piles are installed between the inner piles and the outer piles, and the seepage prevention piles are installed adjacent to the inner piles.

[0014] A method for expanding a ship lock, which expands an existing ship lock using the aforementioned detachable lock chamber structure, includes the following steps: S1. Constructing the foundation pit: Close the floodgate of the upper lock head of the existing ship lock to create a safe dry construction environment by blocking water, and demolish the original lower lock head and navigation wall downstream to form the construction foundation pit; S2. Side-loaded pile foundation construction: drive inner piles, outer piles and seepage prevention piles in the foundation pit, then tie steel bars and formwork on the top of the inner and outer piles, pour the concrete to form a bearing plate, and reserve positioning mortises on the bearing plate, and then install the hanging plate on the inner side of the inner pile. S3. Side wall support assembly installation: Hoist the prefabricated side wall base plate onto the support plate, so that the positioning tenon on the side wall base plate matches the positioning mortise on the support plate to complete the positioning and fixing of the side wall base plate. Then hoist the side wall panel, align the lower end of the side wall panel with the reserved support plate position on the inside of the side wall base plate, and place it vertically on the support plate. Then pre-install the mounting plate on the side wall panel, so that the horizontal surface of the mounting plate is in contact with the side wall base plate. Insert the bolts for fixing. After the side wall panel is completely vertical, tighten the bolts for fixing to complete the installation of the side wall support assembly. S4. Construct the bottom of the gate chamber: Pour the bottom piles, then tie the steel bars and formwork on the top of the bottom piles, pour the bottom slab, and then install the connecting beams on the bottom slab to form a support frame. Pour the node connecting blocks at the intersection of the connecting beams, and then lay the bottom protection material in the rectangular frame inside the support frame. After the bottom protection material is laid, lay the interlocking blocks on the bottom protection material. S5. Seepage prevention and joint treatment: At the junction of the new gate chamber structure and the original structure, as well as the slopes on both banks, a reliable seepage prevention system is constructed, including pouring seepage-proof walls, setting waterstops, and performing curtain grouting to form a continuous water-retaining and seepage-proof line.

[0015] The beneficial effects of this invention are as follows: the side wall support components are connected by mortise and tenon structure, making the side wall support components more modular, which is more conducive to the expansion of the existing lock chamber, with higher expansion efficiency and less impact on navigation.

[0019] Example: like Figures 1-3 As shown, a detachable lock chamber structure includes a load-bearing component 1, a side load component 2, and a side wall support component 3. The bearing component 1 is used to bear the vertical water pressure in the gate chamber and prevent water in the gate chamber from seeping into the foundation. The bearing component 1 includes a bearing base plate 11, bottom piles 12, a support frame 13, node connecting blocks 14 and interlocking blocks 15. The bottom piles 12 are arranged in a rectangular array and are all vertically fixed on the horizontal foundation. The bearing base plate 11 is horizontally fixed on the bottom piles 12.

The node connecting blocks 14 are cast in place at the intersection of the connecting beams 131. The interlocking blocks 15 are located in the number of rectangular frames. The side load assembly 2 is used to bear the horizontal water pressure in the gate chamber and prevent water in the gate chamber from flowing out laterally. The side load assembly 2 includes a hanging plate 21, a bearing plate 22, an inner pile 23, and an outer pile 24. The inner pile 23 and the outer pile 24 are arranged in a rectangular array on the foundation on both sides of the bearing base plate 11, and the inner pile 23 is located on the side closer to the bearing base plate 11. An anti-seepage pile 25 is provided between the inner pile 23 and the outer pile 24, and the anti-seepage pile 25 is arranged adjacent to the inner pile 23. The bearing plate 22 is horizontally fixed on the inner pile 23 and the outer pile 24. The hanging plate 21 is vertically arranged on both sides of the bearing base plate 11. The top end of the hanging plate 21 is fixedly connected to the bearing plate 22, and the bottom end is fixedly connected to the side plate of the bearing base plate 11. The outer wall of the hanging plate 21 is attached to the periphery of the inner pile 23. The connection between the hanging plate 21 and the bearing base plate 11 and the bearing plate 22 is sealed and waterproofed. The side wall support assembly 3 is detachably mounted on the side load assembly 2 via a pin structure, thereby raising the height of the side load assembly 2. The side wall support assembly 3 includes a side wall base plate 31, a side wall panel 32, and a mounting plate 33. The support plate 22 is vertically spaced with a number of positioning mortises 221.
