Design scheme for water intake pump ship

Description :

　　Product Introduction

　　The most traditional way to build pump stations in Rivers and Lakes or reservoirs is to build dams first, then drain the water in the area, build pump houses, and then install pumps, valves, pipelines, control systems, etc. Its characteristics: long construction period, large workload, high cost of pump room, and the higher the water level drop, the higher the cost of pump room; Traditional pump stations have their water intake fixed below the low water level, and the water source is the bottom layer source water with high sand content. The inlet pipe sinks deeper into the bottom of the water, wasting materials. If it is blocked by dirt, it is difficult to detect and clean it; The construction of pump stations has a significant impact on the environment and a low safety factor.

　　Traditional fixed pump stations are mostly built in plain areas, and due to the complex terrain and landforms in most areas, fixed pump stations cannot be constructed. For example, mountainous areas with complex terrain and inconvenient transportation; River bed areas with unstable drift (Yellow River and quicksand layer zones); Tailings treatment, river and lake drainage, and emergency drought resistance projects in mining areas.

　　The modular pontoon pump station solves the problem of difficult water supply under natural conditions such as large flow, large drop and high lift, and is more suitable for water intake projects in rivers, lakes and reservoirs. Modular floating pump stations are widely used in urban water plants, thermal power plants, large chemical enterprises, paper mills, dyeing and printing plants, farmland irrigation, anti welding water intake projects, tailings water intake projects, etc. The product has advanced technology, wide adaptability, and significant economic benefits.

　　Compared with traditional structural pump stations, the floating ship pump station, a special mobile water intake device, not only solves many problems of difficult water intake under special working conditions, but also saves many civil engineering projects such as cofferdam construction, coastal station construction, base excavation, and pump room construction. The total construction investment and daily maintenance costs are saved by more than 50%, and it plays an increasingly important role in various industries such as industry, agriculture, and energy, with significant social benefits.

　　The main features of the floating pipe water intake pump ship are that the pump ship is connected to the shore based main pipeline using HDPE pipes or steel pipes with floats floating on the water surface, which is suitable for water areas with distant water intake points and gentle riverbed slopes in the water source area. At present, the longest floating pipe length of the company's project is 800 meters.

　　Precautions

　　Although floating boats have strong adaptability in water intake and do not require strict location selection like fixed water intake structures, improper location selection can also have adverse consequences on water supply safety and operational management. Therefore, before selecting the water intake location for the floating boat, necessary hydrological and meteorological data should still be obtained, and the underwater terrain and geological data of the water intake location should be mastered. The characteristics of the water intake river should be analyzed and studied, the history of riverbed evolution should be investigated and studied, and the development trend of the river should be analyzed. A more favorable section of the river should be selected as the water intake point. When determining the water intake location for the floating boat, in addition to selecting a stable riverbank without serious erosion or siltation, ensuring the required water quantity and good water quality, being close to water users, convenient construction, and other basic conditions, the characteristics of the floating boat water intake should also be considered. The following points should be noted:

　　(1) The slope of the riverbank should be suitable;

　　The bank slope mainly refers to the bank slope that is neither too gentle nor too steep below the flood level. If the slope is too gentle, it will increase the contact pipe, and for stepped joints, it will increase the number of ship movements, increase the displacement distance of the floating ship plane, and bring inconvenience to the ship movement work; Although a steep slope can shorten the length of the connecting pipe, it can also bring difficulties to the operation of moving ships, transportation, and the construction of inclined water pipes.

　　(2) The water flow should be stable and avoid areas with large currents, rapids, and strong winds and waves;

　　(3) Free from the influence of river navigation and raft placement, the position of the floating ship should be kept at a certain distance from the waterway to avoid collision with each other.

　　(4) During dry season, there should be sufficient water depth; The water depth should be determined based on the tonnage and draft of the floating vessel. For small floating boats, the water depth is generally not less than 1.0m; For larger scale floating boats, the water depth should be 2.0m or greater. If the water depth is insufficient and there is slight siltation, the floating ship will be stranded, and some will be damaged and leak water due to grounding. Therefore, when determining the water depth of the location where the floating ship takes water, full consideration should be given to the siltation situation and changes, and the design water depth should leave room for variation.
