Abstract
Description
Technical Field
[0001] The utility model relates to the field of water-related construction of municipal engineering and water conservancy projects, and in particular to a combined pollution-blocking and isolating device used in deep-water construction areas. Background Art
[0002] During water-related construction of municipal and water conservancy projects, sediment and other particles are easily generated due to disturbances from underwater excavation or leakage from construction machinery, which affects the water quality outside the construction area. Traditionally, if surface oil booms are used, they can only intercept pollutants on the surface of the water body and cannot isolate the diffusion of suspended particles in the water. If fully enclosed temporary retaining walls are used, the water bodies inside and outside the construction area will be disconnected, causing a sharp deterioration in the water quality of the construction area. After the retaining walls are removed, the water quality of water bodies outside the area will be directly impacted. When operating in deep-water construction areas, due to the effect of surge forces, the direct use of steel sheet piles for isolation is prone to safety hazards due to insufficient rigidity. In deep-water areas where water quality protection requirements are high, it is necessary to consider safe, reliable, economical, and easy-to-construct pollution isolation devices. Summary of the Invention
[0003] The purpose of this utility model is to provide a combined pollution-blocking and isolation device for deep-water construction waters, which has sufficient bearing capacity to resist the wave force borne by the device, and isolates the mud and sand particles in the construction area from entering the external water body while ensuring the connection between the internal and external water bodies in the construction area. At the same time, an inflatable oil boom is additionally provided to prevent the spread of oil pollution on the surface of the water body.
[0004] In order to achieve the above-mentioned purpose, the utility model provides a combined pollution-blocking and isolation device for deep-water construction waters, wherein steel pipe piles are arranged at intervals in the device, and the steel pipe piles are driven into the soil layer below the water bottom by piling equipment and fixed; the tops of the steel pipe piles of the device are welded and connected by left and right steel purlins to form a steel sheet pile guide bracket; the steel sheet piles of the device are driven into the soil layer below the water bottom by piling equipment in the guide bracket and fixed, and the steel sheet piles are overlapped with large locks, and a pollution-blocking and isolation keel is formed by combining the steel pipe piles, steel sheet piles and steel purlins on the pile tops; the device lays geotextiles inside and outside the combined pollution-blocking and isolation keel to form a skin, and the geotextiles are pressed and fixed on both sides of the water bottom with environmentally friendly geosand bags; the device sets an inflatable oil boom in the waters outside the construction area, and the oil booms are fixed to the purlins with nylon ropes at intervals.
[0005] Furthermore, steel pipe piles are arranged at intervals and driven into the soil layer below the water bottom by piling equipment to be fixed, ensuring that the steel pipe piles have sufficient bearing capacity to withstand the wave force borne by the device.
[0006] Furthermore, the top of the steel pipe pile is connected by welding the left and right steel purlins to form a steel sheet pile guide bracket, which ensures the positioning and flatness accuracy of the steel sheet pile and restrains the deformation of the top of the steel sheet pile.
[0007] Furthermore, the steel sheet piles are driven into the soil layer below the water bottom in the guide bracket by the piling equipment and fixed. The steel sheet piles are overlapped with large locks to ensure the connection between the water bodies inside the construction area and the water bodies outside the construction area. The pollution isolation keel is formed by the combination of steel pipe piles, steel sheet piles and pile top steel purlins to ensure the overall stability of the keel to withstand the wave force it is subjected to.
[0008] Furthermore, geotextiles are laid inside and outside the combined pollution-blocking isolation keel to form a skin, which ensures the connection between the water inside the construction area and the water body outside the construction area while isolating the mud and sand particles in the construction area from entering the external water body. The geotextile is fixed at the top of the pile with steel wire, and the geotextile is fixed on both sides of the bottom of the water with environmentally friendly geosand bags.
[0009] Furthermore, in the above-mentioned combined pollution isolation device for deep-water construction waters, an inflatable oil boom is set in the waters outside the construction area, and the oil boom is fixed to the purlin with nylon ropes at intervals to prevent the spread of oil pollution on the surface of the water.
[0010] The diameter of the steel pipe piles and the model of the steel sheet piles of the device are determined according to calculations; the model of the steel purlin at the pile top is channel steel 36a; the unit area mass of the geotextile is 300g / m2; the top elevation of the steel pipe piles and steel sheet piles is 500mm higher than the high water level elevation; the applicable water area has a water depth of less than 12m.
[0011] The utility model has the following beneficial effects and improvements:
[0012] The support units of the steel pipe piles and steel sheet piles in the combined pollution-blocking isolation device of the utility model can be finished components or universal products, which do not require excessive on-site cutting and production, are quick and convenient to install, and can achieve the requirements of flatness precision control. While ensuring the connection of water bodies inside and outside the area, it greatly reduces the pollution of particles in the construction area to the external water body. At the same time, it can resist the action of wave forces and ensure the stability of the device. It has good applicability in the environmental protection of water-related construction in municipal engineering and water conservancy projects. BRIEF DESCRIPTION OF THE DRAWINGS
