Summary of the invention

The object of this invention is to provide a kind of low water stage river and adopt the submersible pump method of drawing water, adopt that cost is in this way low, quick construction, do not occupy cultivated land.

The technical scheme that the present invention solves prior art problem is as follows:

The method that low water stage river adopts submersible pump to draw water, in river or on river bank, dig the hole that a degree of depth is not less than 1.5 meters, then in hole, multiple pipe of cement is vertically stacked, stretch out a little ground, river bed pipe of cement or slightly lower than traverse pipe of cement on the pipe of cement on ground, river bed, the pipe of cement of traverse vertically stacks pipe of cement, like this, water level in pipe of cement is just considerably beyond the water level of river, submersible pump is put into pipe of cement, just the water be stored in pipe of cement can be taken away, for agricultural irrigation, when the water in pipe of cement is pumped, the water in river automatically can flow in pipe of cement and supplement.

Described pipe of cement is hollow tube, and cement products company is on sale, and the pipe of cement of different size size is all on sale, for convenience of installing, selecting lightweight specification as far as possible, also can making by hand at scene; Contact surface between the pipe of cement of traverse and the pipe of cement placed vertically is provided with opening, and the pipe of cement making traverse communicates with the pipe of cement placed vertically, thus water can be flowed in the pipe of cement placed vertically in hole by the mouth of pipe of the pipe of cement of traverse.

Accompanying drawing explanation

Fig. 1 is that pipe of cement stacks schematic diagram; Fig. 2 places pipe of cement vertically to stack schematic diagram slightly higher than ground, river bed; Fig. 3 places pipe of cement vertically to stack schematic diagram slightly lower than ground, river bed; Fig. 4 is that another kind of pipe of cement stacks schematic diagram.

Detailed description of the invention

embodiment 1

The height of the water table ratio submersible pump in river is low, can not directly put into submersible pump to draw water.Solution is that in river, to dig a degree of depth with excavator be the hole of 1.9m, as shown in Figure 1, vertically stacking into two height in hole is 1m, internal diameter is 1m, thickness is the pipe of cement of 5cm, then on the pipe of cement exposing river bed, traverse one has the pipe of cement of two mouths, the pipe of cement of traverse or less parallel parallel with water (flow) direction, the mouth of pipe of the pipe of cement placed vertically aims at an opening of traverse pipe of cement, another opening of traverse pipe of cement vertically places a pipe of cement, schematic diagram after installing as shown in Figure 2, like this, submersible pump can be put into pipe of cement, water level in pipe of cement far exceedes the height of submersible pump, and pipe of cement has water collecting function, water can be extracted continuously out for agricultural irrigation.River enters the pipe of cement placed vertically from the mouth of pipe of the pipe of cement of traverse, because there is certain distance on the mouth of pipe of the pipe of cement of traverse and ground, river bed, can prevents the silt of korneforos from flowing in vertical pipe of cement, can prevent water pump from blocking.

embodiment 2

On bank, river, digging a degree of depth with excavator is the hole of 2.1m, as shown in Figure 1, vertically stacking into two height in hole is 1m, internal diameter is 2m, thickness is the pipe of cement of 5cm, then at the pipe of cement having two mouths lower than traverse on the pipe of cement of river bed one, pipe of cement and the water (flow) direction vertical or near normal mutually of traverse, the mouth of pipe of the pipe of cement placed vertically aims at an opening of traverse pipe of cement, another opening of traverse pipe of cement vertically places a pipe of cement, schematic diagram after installing as shown in Figure 3, like this, submersible pump can be put into pipe of cement, water level in pipe of cement far exceedes the height of submersible pump, and pipe of cement has water collecting function, water can be extracted continuously out for agricultural irrigation.River enters the pipe of cement placed vertically from the mouth of pipe of the pipe of cement of traverse, because the mouth of pipe of the pipe of cement of traverse is lower than the ground of river bed, also the method can be adopted to pump river in the river that water level is very low, water inlet is not parallel with river water (flow) direction, can prevent the silt of korneforos or the floating foreign matter of river surface from entering pipe of cement to greatest extent, prevent water pump from blocking.

embodiment 3

As shown in Figure 4, one 1.9 meters dark holes are dug at river bank with excavator, in hole, vertically stack three height is 1m, internal diameter is 1.6m, thickness is the pipe of cement of 5cm, then at river bed traverse pipe of cement, the face that the pipe of cement placed vertically contacts with the pipe of cement of traverse is provided with opening, the pipe of cement mouth of pipe of traverse is communicated with the pipe of cement placed vertically, such river just can flow in the pipe of cement placed vertically by the pipe of cement of traverse, in order to prevent the foreign matter of silt and river water float from following river to flow in pipe of cement, the pipe of cement mouth of pipe of traverse a little for the downstream.This method, the water stored in the pipe of cement placed vertically is more than 4m3, and water level far exceedes the height of submersible pump, draws water by submersible pump.If the area of irrigating is comparatively large, the water of needs is more, can increase the degree of depth in hole, increases the internal diameter of pipe of cement or do several such device more.

The material pipe of cement that this method adopts can be bought in cement products company, but also oneself makes, and therefore, adopt method of the present invention, can utilize the river of low water stage, quick construction, engineering cost is low, does not occupy cultivated land.

The above embodiments are only better cases of the present invention, instead of restriction of the present invention.The number put into of vertical pipe of cement can according to irrigate land area actual water requirement and determine, the large I of specification of pipe of cement is determined as required.Such as need the area of irrigation very large, need the metered flow of submersible pump very large, this ensures abundant water to extract with regard to needing, therefore need vertically to stack multiple pipe of cement, or dig several hole more, put into pipe of cement, the water pipe of cement in multiple hole is together in parallel.These methods all come from the present invention, also fall within the scope of protection of the present invention.
