Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of water conservancy engineering, and particularly relates to a regulation pipe system for regulating the moisture content and temperature of soil at the bottom of a channel. BACKGROUND

[0002] In winter in cold regions, the ground soil around the channel body below the water channel may freeze due to excessively low temperature, forming frozen soil, causing the soil body to have a frost heaving effect, and further causing uneven uplift of the channel foundation, thereby causing damage to the structure of the water channel body, causing the water channel body structure to crack, leak or even collapse, and seriously affecting the service life. In summer, there may be a drought, at which time the ground soil around the channel body below the water channel loses water and dries, on the one hand causing the ground soil to shrink due to loss of water and drying, thereby causing deformation damage to the water channel body; on the other hand, the loss of water and drying of the ground soil and the drying of the water channel body itself may cause the risk of cracking of the water channel body.

[0009] In the technical scheme, the distance between the serpentine pipeline and the bottom surface of the water channel body is 10-20 cm, and the single side of the serpentine pipeline of each pipeline system module has 8-20 bends.

[0038] 1. Reducing the water content of the soil at the bottom of the water channel (this operation is performed before the soil is about to freeze in winter, i.e., before the soil freezes);

[0039] Connecting the first main pipe 1 and the second main pipe 2 to the water vapor extraction device to generate negative pressure in each pipe system module 3, and then extract the water vapor in the soil at the bottom of the water channel body 0, thereby reducing the water content of the soil at the bottom of the water channel body 0, and effectively preventing the water channel body from being damaged by frost heaving.

[0040] Further, referring to the drawings, Figure 6 The water vapor extraction device can also be in the form of a combination of a vacuum pump and a water pump. A suction pipe 61 is inserted into the vertical pipe 5 of the main pipe, the suction pipe 61 extends into the bottom of the main pipe, and a sealing cover 63 is installed at the top end of the vertical pipe 5 to form a sealed connection between the suction pipe 61 and the top end of the vertical pipe 5, the suction pipe 61 is connected to the inlet of the water pump; an air extraction interface is also provided on the sealing cover 63, the air extraction interface is connected to the inlet of the vacuum pump through an air extraction pipe 64, thereby realizing the vacuum extraction of the main pipe and each pipe system module 3 by the vacuum pump; a valve 65 is also provided on the connecting pipe between the suction pipe 61 and the inlet of the water pump, during the operation of the vacuum pump, the valve 65 is closed and the water pump does not work, thereby ensuring the vacuum extraction effect of the vacuum pump on the main pipe and each pipe system module 3, and under the negative pressure state, the water in the soil at the bottom of the water channel body 0 passes through the filter cloth and the water-permeable hole into each pipe system module 3, and under the action of gravity, the water in the pipe system module 3 flows into the main pipe; after the vacuum pump works for a period of time, the vacuum pump is turned off, the water pump is started, and the valve 65 is opened, and the accumulated water in the main pipe is extracted through the suction pipe 61.

[0041] 2. Water supplement to the soil at the bottom of the water channel:

[0042] The first main pipeline 1 and the second main pipeline 2 are connected to the water supplement device (which can be a water supplement vehicle connected to the top end of the vertical pipeline 5, and then water is sent to the first main pipeline 1 and the second main pipeline 2, or a water pump is used to extract water from other areas and send it into the first main pipeline 1 and the second main pipeline 2), and water is sent into each pipeline system module 3 to supplement the water in the bottom soil of the water channel, thereby effectively preventing the problem of water channel damage caused by water loss and drying of the bottom soil of the water channel in drought conditions.

[0043] 3. Increase the temperature of the bottom soil of the water channel:

[0045] Further, in order to increase the airflow speed of the entire system, the hot air generating device can be connected to the first main pipeline 1, and the second main pipeline 2 is connected to the air extraction device, both of which work at the same time, thereby increasing the airflow speed of the entire system, i.e. increasing the heat exchange rate. Further, the air outlet of the air extraction device can be connected to the air inlet of the hot air generating device through a pipeline to form a circulation, which can utilize waste heat to reduce energy consumption.

[0046] For ease of description, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to describe the relationship of one element or feature to another element or feature shown in the drawings. It should be understood that, in addition to the orientation shown in the drawings, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the drawings is inverted, the element described as being "below" other elements or features will be positioned "above" the other elements or features. Therefore, the exemplary term "below" can include both upward and downward orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative description used herein can be interpreted accordingly.
