Skill in the artThe technical scheme has the following substantial technical effects and the realization process thereof: specification of the buoy: the buoy is a food-grade PE customized buoy, the specification is shown in the following figure, and a single buoy can bear 6KG load (the water density is 1.0 multiplied by 10 KG/m) after being completely immersed in water³In the formula of buoyancy F ═ ρ gV rows).

Calculating snow load:

the snow load is 0.25KN/m according to the standard consideration of the first meeting in two decades in the northern area³. The weight of snow born by the system per square meter is 25.51KG, and the weight of the coated cloth after being stained with water vapor is about 0.55KG/m after the coated cloth is placed outdoors for a period of time³The total weight of the other auxiliaries, taken together, is 28.06KG/m, calculated as 2KG³. The required number of buoys is 28.06 (total weight)/6 (maximum weight borne by a single buoy) to 4.68. Considering that the number of the floating cylinders is reduced by half after the adjacent coating cloth parts share the floating cylinders, the number of the required floating cylinders under each square meter of coating cloth is 9-10. Considering according to 9 pontoons, the pontoons are arranged according to the interval of 50CM, and the pontoons can be just distributed. And the number of the buoys under each square meter of the coating cloth is 1 (one buoy at the center) +8/2 (8 buoys which are shared by the edges and other parts of the coating cloth) is 5 to 4.68, so that the arrangement rule of the buoys is determined to be 50CM spacing arrangement.

As an optional addition: pilot test description was performed:

a research and development engineering site is selected in a new safety side town in a fixed side county of Shaanxi province, and research and development are carried out by relying on a rain collection and supplement irrigation project in the fixed side county and taking a high-level reservoir constructed in a photovoltaic water pumping station irrigation area on the west side of the rain collection and supplement irrigation project on the new safety side as a research sample. This high-order cistern has used 500g high-strength silk coated fabric to cooperate the floated way of flotation pontoon to make one set of evaporation preventing system, and the preparation details and main points are as follows:

size of pool

The width of the top of the tank is 23m, and the width of the tank is 24 m; the width of the pond bottom is 16m, and the width of the pond bottom is 14 m; the height of the pool is 6 m. The pool wall of the pool is 7m long, the length from the overflow line to the pool bottom along the pool wall is about 6m, and the coating cloth on the pool bottom is laid north and south. The size of the reservoir can be obtained according to a prismoid formula: V-1/3H (S1+ S2+ V S1S2) ═ 1/3H (23 x 24+16 x 14+ V23 x 24 x 16 x 14) ═ 2255m

Technical key points and main construction mode

The bottom part of the pool: cutting 14m of coating cloth to be used for the bottom of the pool, and paving 6 pieces of coating cloth in the north-south direction to fully pave the bottom of the pool. (the width of the coating cloth is 2.9m, the edge pressing space is needed when the coating cloths are connected, and the length of the connecting buckle is 8cm, the edge pressing space is set to be 7cm, so 6 pieces of coating cloths are arranged at the bottom of the pool, if the system is used in a subsequent pool, part of the coating cloths at the bottom of the pool can be combined and connected to the bottom of the full-paved pool after buoys are arranged on the small pieces of coating cloths at intervals of 50cm, and the effect of the two pieces of coating cloths is completely consistent).

The part of the pool wall: the length of the tank wall is 7m, the width of the tank top is about 2m, the tank top reaches the guardrail, partial space required by the soil-filled woven bag is considered, and 10m long coated cloth can cover the soil-pressed bag and the tank wall. (the subsequent water tank uses the system, preferably uses a whole piece of coating cloth with proper length according to the actual length of the tank wall, arranges the buoys on the length part below the overflow line according to the subsequent calculation interval, if the modular coating cloth is directly used for connection, the unnecessary damage to the coating cloth connection section can be caused due to the fact that the coating cloth is concentrated on a plurality of connection points due to the dead weight of the coating cloth in a long time). And (4) laying the coating cloth on the wall of the pool from top to bottom according to the field condition, cutting off the redundant part and connecting the redundant part. And after the laying is finished, feeding water into the pond.

The whole system is developed for 4 months, and in various schemes, the evaporation prevention system is preferably selected along with the horizontal sedimentation type:

the calculation process and the actual effect show that the anti-evaporation system is feasible.

Influence of freezing of pond water and strong wind on system in winter

After the outside temperature drops in winter, because the water in the pool is in the soil layer and the coating cloth is wrapped, the cold air cannot directly reach the surface of the pool water, and the temperature of the pool water cannot be rapidly reduced to the freezing point like the outside temperature. Therefore, the water in the pool can not be guaranteed to freeze in the early snow season, and the freezing thickness of the water in the pool can not be guaranteed to bear enough snow load; however, after the initial snow is over, due to the fact that the outside is at low temperature for a long time during snow elimination, the pool water can be slowly frozen, and the coating cloth can be always above the water surface by matching with the buoyancy of the floating barrel.

The coated cloth is connected once every 50cm, and a 7cm blank pressing space is arranged in the middle of the coated cloth when the coated cloth is connected, so that a large amount of wind hardly penetrates below the coated cloth; the system has a certain dead weight, the buoy and the water surface have a certain surface tension effect, and a small amount of wind enters the lower part of the coating cloth and cannot jack or lift the coating cloth. In order to ensure that no accident happens, three steel ropes are transversely pulled on the top of the pool in the construction, and two sides of each steel rope are fixed by ground anchors and are tightened by a rope tightening device so as to prevent the coating cloth from being possibly damaged by wind.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to illustrate the principles of the utility model, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, and the utility model is to be limited to the embodiments described above.
