Abstract
Description
Technical Field
[0001] This invention relates to the field of emergency evacuation, and in particular to an emergency evacuation system for a lock chamber. Background Technology
[0002] According to Section 6.3.4 of the "Code for Fire Protection Design of Hydropower Projects" GB50872-2014, evacuation ladders should be installed on both sides of the gate wall, leading from the bottom of the gate chamber to the top of the gate wall, and the distance between them on the same side should not exceed 50 meters.
[0003] Currently, one method for emergency evacuation in lock chambers is to install ladders as required by standard GB50872-2014. In the event of a fire or other emergency, personnel on board can evacuate via these ladders. However, ladders are vertical, and lock chambers can be tens of meters deep, making it difficult for those with poor physical strength or a fear of heights to climb. Moreover, in an emergency, if those in front cannot climb up, it will affect the evacuation of those behind, posing a life-threatening risk to those on board. Another method involves installing platforms, Class A fire doors, and horizontal evacuation passages every 6-10 meters along the side walls of the lock chamber, with Class A fire doors connecting the platforms and the horizontal evacuation passages. In the event of a fire or other emergency, if the elevation of the ship's side is not significantly different from the elevation of the platform in front of the doorway, personnel on board can be evacuated by setting up a plank between the ship's side and the platform. However, when the elevation difference between the ship's side and the evacuation platform is large, the angle and slope of the plank between the ship's side and the evacuation platform will be steep, which is not conducive to the evacuation of personnel on board. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide an optimized emergency evacuation system for lock chambers, which facilitates the emergency evacuation of personnel in lock chambers.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an emergency evacuation system arrangement for a lock chamber, wherein multiple rows and columns of stairs and platforms leading to evacuation platforms on each floor are set on the surface of the lock chamber side wall. The stairs and platforms are arranged in parallel at certain intervals along the height direction of the lock chamber side wall. A railing post is set on the water-facing side of the stair treads of the stairs and platforms. A handrail is set between two adjacent railing posts. The handrail is hinged to the post at one end and can be detached at the other end between any two adjacent posts.
[0006] Furthermore, the handrail can be flexible or rigid.
[0007] Furthermore, a fixed handrail is installed on the gate chamber side wall on the backwater side of the stair slab of the staircase and platform.
[0008] Furthermore, the fixed handrail can be a rigid handrail or a flexible handrail.
[0009] Furthermore, the upper platform of the staircase and platform is connected to the existing gate chamber side wall evacuation platform, and the bottom plate elevation of the lower platform of the staircase and platform is the same as the bottom plate elevation of the gate chamber side wall evacuation platform adjacent to the upper platform.
[0010] Furthermore, the staircase and platform are embedded in the side wall of the gate chamber.
[0011] Furthermore, the staircase and platform are reinforced concrete or steel structures.
[0012] Furthermore, the railing posts are made of steel or reinforced concrete, with steel rings or pins pre-installed on both the left and right sides. Furthermore, when the railing handrail is a flexible railing, it uses stainless steel chains; when it uses a rigid connection, it uses stainless steel pipes.
[0013] Furthermore, when the fixed handrail is a flexible handrail, it uses a stainless steel chain; when it is a rigid handrail, it uses a stainless steel tube.
[0014] The beneficial effects of this invention are: in the event of a fire or other emergency on a ship inside the lock chamber, regardless of the ship's hull elevation (which may be arbitrary and differs from the elevation of each evacuation platform), personnel can quickly evacuate via this staircase. Compared to the current practice of using ladders for evacuation or constructing evacuation platforms only every 6-10 meters in lock chambers, this significantly improves the speed of evacuation and greatly protects the lives of those on board.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0021] like Figure 1-3 As shown, the emergency evacuation system of the lock chamber of the present invention is arranged with multiple rows and columns of stairs and platforms 1 leading to each evacuation platform on the surface of the lock chamber side wall 5. The stairs and platforms 1 are arranged parallel at certain intervals along the height direction of the lock chamber side wall 5. A railing post 4 is provided on the water-facing side of the stair slab of the stairs and platforms 1. A railing handrail 2 is provided between two adjacent railing posts 4. The handrail 2 is hinged to the post 4 at one end and can be detached at the other end between any two adjacent posts 4.
[0022] Preferably, the handrail 2 is flexible or rigid.
[0023] Furthermore, a fixed handrail 3 is provided on the gate chamber side wall 5 on the backwater side of the stair slab of the staircase and platform 1.
[0024] Currently, the fixed handrail 3 is either a rigid handrail or a flexible handrail.
[0025] Furthermore, the upper platform of the staircase and platform 1 is connected to the existing gate chamber side wall evacuation platform, and the bottom plate elevation of the lower platform of the staircase and platform 1 is the same as the bottom plate elevation of the gate chamber side wall evacuation platform adjacent to the upper platform.
[0026] Preferably, the staircase and platform 1 are embedded in the side wall 5 of the gate chamber.
[0027] Preferably, the staircase and platform 1 is a reinforced concrete structure or a steel structure staircase.
[0028] Preferably, the railing post 4 is a steel structure or a reinforced concrete structure, with steel rings or pins reserved on both the left and right sides. Preferably, when the railing handrail 2 is a flexible railing, it uses a stainless steel chain; when it is a rigid connection, it uses a stainless steel pipe.
[0029] Preferably, when the fixed handrail 3 is a flexible handrail, it is made of stainless steel chain, and when it is a rigid handrail, it is made of stainless steel pipe.
[0030] Specifically, the staircase and platform 1 of the present invention are arranged in parallel at certain intervals along the vertical direction. The staircase and platform 1 are closely attached to the completed gate chamber side wall 5. The railing posts 4 and flexible or rigid handrails 2 connecting each post 4 are provided on the open side (water side) of the staircase and platform 1. The handrails 2 are hinged to the posts 4 at one end and can be detached at the other end between any two adjacent posts 4. The rigid or flexible fixed handrails 3 are firmly connected to the gate chamber side wall 5.
[0031] The completed staircases and platforms (including stair beams) connecting the floors are generally parallel single-flight staircases made of reinforced concrete. They can be precast or cast-in-place and should be poured with impermeable concrete. They are arranged parallel to each other at regular intervals (approximately 6-10 meters per floor) along the vertical direction. Steel structure staircases can also be used, in which case anti-corrosion treatment should be performed. Their fire resistance rating should meet the requirements of Class II fire resistance rating in the current national fire protection code.
[0032] The railing posts 4 located on the water-facing side of the stair slab and platform 1 are generally made of steel (steel pipe or structural steel), but can also be made of reinforced concrete; steel rings or pins are reserved on both sides. When steel structure posts are used, anti-corrosion treatment should be done, preferably using stainless steel; when reinforced concrete structures are used, waterproofing and seepage prevention treatment should be done, and seepage-proof concrete should be used for pouring.
[0033] The flexible or rigid handrail 2 connecting each railing post 4 is hinged at one end to the post 4 and can be detached after being connected to the post 4 at the other end, so that people on board can pass through for evacuation in an emergency. When using a flexible handrail, stainless steel chains can be used; when using a rigid handrail, stainless steel pipes can be used. When other materials are used, fireproofing and corrosion protection treatments should be applied.
[0034] The fixed handrail 3 on the side of the gate chamber side wall 5 can be either rigid or flexible. When using a rigid handrail, stainless steel pipe can be used. When using a flexible handrail, stainless steel chain can be used. Other materials can also be used, but they should be fireproof and corrosion-resistant. It should be firmly welded to the gate chamber side wall 5 via embedded parts or connected firmly via expansion bolts. Regardless of the connection method, the connection area should be locally treated with anti-corrosion measures after connection.
[0035] The present invention includes platforms, emergency evacuation passages, and smoke-proof stairwells that have been completed on each floor leading to the wall of the gate chamber.
[0036] All products mentioned above should be high-quality products that meet current national standards.
[0037] This invention is applicable to the emergency evacuation layout of lock chambers. The lock chamber sidewall is recessed a certain width from the platform side towards the lock wall. Within this width, a one-way straight staircase and platform are arranged downwards from the platform (assuming the platform elevation is H, and the vertical spacing between each level is 6 meters) to the next platform elevation (H-6). This arrangement is repeated sequentially along the height of the lock chamber sidewall. In the event of a fire or other emergency on a ship inside the lock chamber, the ship's hull elevation may be arbitrary, regardless of the height difference between it and the evacuation platforms at each level. Personnel on board can quickly evacuate via this staircase. Compared to the current practice of using ladders for evacuation or only constructing evacuation platforms every 6-10 meters in height in lock chambers, this significantly improves the speed of evacuation and greatly protects the lives of those on board.
[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention. The scope of protection of the present invention also covers emergency evacuation of ship lift cabins with similar lock chamber arrangements.
