Description
Technical Field
[0001] The invention relates to a heavy-duty cover for a floating dock sewage well. Background Art
[0002] At present, in order to meet the requirements of green environmental protection, sewage wells need to be set up around the flat-bottomed pontoons of floating docks. In order to meet the passage of personnel and heavy engineering vehicles, a special structure cover needs to be installed on the sewage well, so that it can not only meet the requirements of waste discharge, but also prevent people from falling or spraining their feet. It must also meet the requirement that the heavy engineering vehicles constructing in the floating dock pontoons have a traffic load of 15 tons. At the same time, it must also have the characteristics of simple construction, easy installation, flexible operation and easy maintenance. Therefore, a scientific, reasonable, economical, safe and practical sewage well cover plays a vital role. Summary of the invention
[0003] The purpose of the present invention is to provide a heavy-duty cover for a floating dock sewage well which is simple to construct, convenient to install, flexible to operate and easy to maintain, and which meets the requirements of green environmental protection and has strong practicality.
[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a heavy-duty cover for a sewage well of a floating dock, comprising a dock wall side fixing piece (1), a longitudinal auxiliary reinforcing rib (2), a longitudinal main reinforcing rib (3), a bow fixing piece (4), a transverse anti-falling rod (5), a transverse reinforcing rib (6), a dock middle side fixing piece (7), a stern fixing piece (8) and a bracket leg (9), wherein the dock wall side fixing piece (1), the longitudinal auxiliary reinforcing rib (2), the longitudinal main reinforcing rib (3) and the dock middle side fixing piece (7) are arranged in sequence in the longitudinal direction, and the transverse anti-falling rod (5) is connected to the dock wall side fixing piece (1), the longitudinal auxiliary reinforcing rib (2), the longitudinal main reinforcing rib (3) and the dock middle side fixing piece (7) in a longitudinal direction. The auxiliary reinforcing ribs (2), the longitudinal main reinforcing ribs (3) and the dock middle side fixing piece (7) are fixedly connected in sequence respectively; the transverse reinforcing ribs (6) are fixedly connected in sequence respectively to the dock wall side fixing piece (1), the longitudinal auxiliary reinforcing ribs (2), the longitudinal main reinforcing ribs (3) and the dock middle side fixing piece (7); the bow fixing piece (4) is fixedly connected in sequence to the longitudinal auxiliary reinforcing ribs (2) and the longitudinal main reinforcing ribs (3); the stern fixing piece (8) is fixedly connected in sequence to the longitudinal auxiliary reinforcing ribs (2) and the longitudinal main reinforcing ribs (3); and the top of the bracket leg (9) is fixedly connected to the longitudinal main reinforcing ribs (3).
[0005] A pad (10) is installed at the bottom of the bracket leg (9).
[0006] The heavy-duty cover of the sewage well of a floating dock disclosed by the present invention has the advantages of simple construction, convenient installation, flexible operation and simple maintenance, which not only meets the requirements of green environmental protection but also has strong practicality. While ensuring effective filtering of waste, it can withstand the passage of heavy engineering vehicles. The cover is prefabricated as a whole and then installed, and there is no need to fix any auxiliary parts in the sewage well in advance. The cover is simple to prefabricate, convenient to install, flexible to operate, and economical and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] like Figures 1 to 3As shown, the heavy cover of the floating dock sewage well includes a dock wall side fixing part 1, a longitudinal auxiliary reinforcement rib 2, a longitudinal main reinforcement rib 3, a bow fixing part 4, a transverse anti-falling rod 5, The transverse reinforcement ribs 6, the dock middle side fixings 7, the stern fixings 8, the bracket legs 9 and the pads 10 are arranged in sequence in the longitudinal direction at a certain interval according to the design requirements according to the size and load value of the sewage well. Then the transverse anti-fall rod 5 is fixedly connected with the dock wall side fixings 1, the longitudinal auxiliary reinforcement ribs 2, the longitudinal main reinforcement ribs 3 and the dock middle side fixings 7 in sequence, and the transverse reinforcement ribs 6 are fixedly connected with the dock wall side fixings 1, the longitudinal auxiliary reinforcement ribs 2, the longitudinal main reinforcement ribs 3 and the dock middle side fixings 7 in sequence. Then the bow fixings 4 are fixedly connected with the longitudinal auxiliary reinforcement ribs 2 and the longitudinal main reinforcement ribs 3 in sequence, and the stern fixings 8 are fixedly connected with the longitudinal auxiliary reinforcement ribs 2 and the longitudinal main reinforcement ribs 3 in sequence. The top of the bracket leg 9 is fixedly connected with the longitudinal main reinforcement ribs 3, and the pads 10 are fixed to the bottom of the bracket legs 9. When in use, two people put the heavy sewage well cover into the sewage well as a whole to ensure that the bottom pads 10 is in contact with the bottom plate of the sewage well and the dock wall side fixing piece 1, the dock middle side fixing piece 7, the bow fixing piece 4 and the stern fixing piece 8 are overlapped on the sewage well 11 opening, and the installation can be completed; if it needs to be disassembled when cleaning the sewage well, two people can lift the entire heavy sewage well cover. The heavy sewage well cover of the floating dock of the present invention mainly relates to the shipbuilding industry, and is a floating dock, a main device for repairing and building ships. The floating dock is a huge concave-shaped cabin with dock walls on both sides, a buoyancy box at the bottom, and a flat-land ship with a special structure with open bow and stern ends; in line with the concept of green environmental protection, the ships under construction in the floating dock cannot be directly discharged into the seawater due to the waste generated during operations such as washing, sandblasting, and painting. Therefore, drainage ditches 12 are set around to collect the waste into the sewage well 11, and then injected into the sewage tank through pipelines, and then discharged into the seawater after treatment. This heavy cover is an opening device placed at the opening of the sewage well, which can withstand the load of heavy engineering vehicles, and is easy to install, flexible to operate, and simple to maintain.
