Description

Technical Field

[0001] The utility model relates to the technical field of channel structures, in particular to an integrated pumping and drainage structure for a water supply channel. Background Art

[0002] my country's water resources are unevenly distributed, with water shortages particularly acute in the northwest. To address this regional imbalance, a large number of long-distance water diversion projects have been constructed in recent years. However, these long-distance water supply projects inevitably require crossing unusual land areas, and water seepage is a natural risk in channel structures. This water seepage into the channel soil can damage channel slopes, particularly in high-altitude, cold regions with large diurnal and seasonal temperature swings. Directing or draining this seeping water can effectively ensure the safe and long-term operation of water supply channels.

[0003] Therefore, there is an urgent need for an integrated pumping and drainage structure for water supply channels to solve the problem of guiding or pumping out water seeping from the channels. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an integrated pumping and drainage structure for a water supply channel, so as to solve the problem of guiding or pumping out water seeping from the channel.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A pumping and drainage integrated structure for a water supply channel, characterized in that it includes a longitudinal drainage corridor, a transverse connecting pipe, a vertical drainage well and a drainage mechanism, the longitudinal drainage corridor includes a flexible water pipe and a permeable hollow pile, the permeable hollow pile is buried at the bottom of the channel and arranged longitudinally along the channel, the flexible water pipe is arranged at the inner center of the permeable hollow pile along the channel direction, the inner wall of the permeable hollow pile and the flexible water pipe are filled with anti-filter sand and gravel, the vertical drainage well is buried in the soil beside the channel, one end of the transverse connecting pipe passes through the permeable hollow pile and the anti-filter sand and gravel and is connected to the flexible water pipe, and the other end is connected to the inner cavity of the vertical drainage well, and the drainage mechanism is used to pump water in the vertical drainage well into the channel.

[0007] To optimize the above technical solutions, specific measures taken also include:

[0008] Furthermore, the cross-section of the permeable hollow pile is rectangular.

[0009] Furthermore, the outer side of the flexible water pipe is wrapped with a layer of aerogel felt, and the filter sand is filled between the inner wall of the permeable hollow pile and the aerogel felt.

[0010] Furthermore, the horizontal height of the end of the transverse connecting pipe close to the longitudinal drainage corridor is higher than the horizontal height of the end close to the vertical drainage well.

[0011] Furthermore, the drainage mechanism includes a water pump and a water drainage pipe. The water pump is arranged at the bottom of the inner cavity of the vertical drainage well. One end of the water drainage pipe is connected to the water pump, and the other end extends from the upper end opening of the vertical drainage well and extends to connect with the channel.

[0012] Furthermore, a liquid level identification sensor is installed on the inner wall of the vertical drainage well, and a channel water level anti-overflow identifier is installed at the channel mouth. The liquid level identification sensor and the channel water level anti-overflow identifier are electrically connected to the water pump respectively.

[0013] Furthermore, a foldable solar panel is provided at the top wellhead of the vertical drainage well, and the solar panel is electrically connected to the water pump for supplying power to the water pump.

[0014] Furthermore, it also includes a composite lining structure. The channel is located on both sides of the longitudinal drainage corridor and is provided with a composite lining structure. The composite lining structure is provided with a precast concrete slab layer, a cement mortar protective layer and an anti-seepage geomembrane in sequence from top to bottom.

[0015] Furthermore, the spacing between the composite lining structures on both sides gradually increases from bottom to top.

[0016] Furthermore, it also includes a concrete guide plate, which is in the shape of a rectangular column, and a wider side surface is provided with several parallel guide grooves along the axial direction. The concrete guide plates are symmetrically arranged below the anti-seepage geomembranes on both sides, and the upper surface of the guide grooves of the concrete guide plates is in contact with the lower surface of the anti-seepage geomembrane, and the bottom ends of the concrete guide plates on both sides are respectively connected to the longitudinal drainage corridor.

[0017] The beneficial effects of the utility model are:

[0018] The utility model utilizes the good water absorption of the flexible water pipe, as well as the special siphon and capillary action, to collect water leaking from the bottom of the channel into the flexible water pipe under the action of the siphon and capillary action of the flexible water pipe, and then collects the water from the flexible water pipe into the vertical drainage well through the transverse connecting pipe. At the same time, the permeable hollow piles and the anti-filter sand and gravel can filter the sediment at the leakage point, thus avoiding the clogging of the flexible water pipe. Moreover, the application of the anti-filter sand and gravel and the flexible water pipe can ensure that the leaked channel water can be collected into the flexible water pipe of the longitudinal drainage corridor without spreading in other directions, thereby avoiding inducing the inferior properties of special soil. By setting the vertical drainage well along the channel, the vertical drainage well can not only be used to pump out and store the leaked channel water, or cooperate with the drainage mechanism to drain the accumulated water back into the channel, but also can act as an anti-slip pile, which can prevent disasters such as landslides and collapses on the channel slopes, solve the problem of guiding or pumping out the water seeping from the channel, and increase the protection capability and stability of the channel structure.

[0019] The longitudinal drainage corridor of the utility model is a combination of permeable hollow piles with a rectangular cross section and a flexible water pipe built in. The permeable hollow piles are used to prevent the freezing, thawing and deformation of the soil from squeezing the water pipe, causing the water pipe to deform and resulting in a decrease in drainage efficiency. In addition, its hollow structure with a rectangular cross section not only has the function of bearing a greater load than traditional circular hollow piles, but also has a low cost and good economic value, reducing engineering costs and better reflecting its superiority. The aerogel felt material wrapped around the flexible water pipe can play a role in heat preservation. When the temperature is very low or drops sharply, the seeping water in the drainage pipe is not easy to freeze.

[0020] This utility model features a vertical drainage well with a pumping function. During the water delivery process, leaked canal water is first collected in the longitudinal drainage pipe and then directed through the transverse drainage pipe to the vertical drainage well. When the leaked water reaches a certain level, it is pumped back into the canal through the drainage well. This pumping function of the vertical drainage well not only largely prevents damage such as landslides and collapses caused by water leakage in the canal foundation due to reduced soil strength, but also reduces water waste.

[0021] The vertical drainage well of the utility model has a liquid level identification function and a wireless transmission function, which can indirectly reflect the leakage situation of the channel section in real time. When the leaking channel base water passes through the longitudinal drainage pipe and flows through the horizontal drainage pipe into the vertical drainage well, every time the water level in the well reaches the set height, the water level sensor installed on the inner wall of the drainage well will send a signal. At this time, the wireless transmission function can transmit the signal to the water pump, and the water pump starts working to extract the accumulated water from the vertical drainage well and return it to the channel. The entire structure and function are more intelligent, which not only saves manpower and material resources for channel maintenance, but also can accurately maintain and control leakage in the regional section, and realizes the integration of the pumping and drainage functions of the water supply channel.

[0022] The material used for the vertical drainage well of the utility model is reinforced concrete, so that the drainage well not only has the function of pumping out leaked water from the channel, but also plays a role equivalent to an anti-slip pile during operation, providing a certain anti-slip protection for the channel slope.

[0023] This foldable solar panel receives sunlight, converting it into electricity to pump out water from a vertical drainage well. This effectively addresses the lack of conventional electricity in deserted areas. It also provides insulation for unpumped water, preventing it from freezing and becoming difficult to drain during low temperatures. The solar panel remains folded during drainage, facilitating operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The utility model is described in detail below with reference to the accompanying drawings.

[0031] As attached Figure 1 and attached Figure 2As shown, an integrated pumping and drainage structure for a water supply channel in an embodiment of the present invention includes a longitudinal drainage pipe gallery 3, a transverse connecting pipe 4, a vertical drainage well 5 and a drainage mechanism. The longitudinal drainage pipe gallery 3 includes a flexible water pipe 31 and a permeable hollow pile 32. The permeable hollow pile 32 is buried at the bottom of the channel and arranged longitudinally along the channel. The flexible water pipe 31 is arranged at the inner center of the permeable hollow pile 32 along the channel direction. The inner wall of the permeable hollow pile 32 and the flexible water pipe 31 are filled with anti-filter sand and gravel 35. The vertical drainage well 5 is buried in the soil beside the channel. One end of the transverse connecting pipe 4 passes through the permeable hollow pile 32 and the anti-filter sand and gravel 35 and is connected to the flexible water pipe 31, and the other end is connected to the inner cavity of the vertical drainage well 5. The drainage mechanism is used to pump water in the vertical drainage well 5 into the channel.

[0032] The utility model uses the good water absorption of the flexible water pipe 31 and the special siphon and capillary action to collect water leaking from the bottom of the channel into the flexible water pipe 31 under the action of the siphon and capillary action of the flexible water pipe 31, and then collects the water from the flexible water pipe 31 into the vertical drainage well 5 through the horizontal connecting pipe 4; at the same time, the permeable hollow piles 32 and the anti-filter sand and gravel 35 can filter the mud and sand at the leakage point, avoiding the clogging of the flexible water pipe 31, and the application of the anti-filter sand and gravel 35 and the flexible water pipe 31 can ensure that the leaked channel water can be collected into the flexible water pipe 31 of the longitudinal drainage corridor 3 without spreading in other directions, thereby avoiding inducing the inferior properties of special soil. By setting the vertical drainage well 5 along the channel, the vertical drainage well 5 can not only be used to pump out and store the leaked channel water, or cooperate with the drainage mechanism to drain the accumulated water back to the channel, but also can play the role of anti-slip piles, which can prevent disasters such as landslides and collapses on the channel slopes, solve the problem of guiding or pumping out the water seeping from the channel, and increase the protection capacity and stability of the channel structure.

[0033] In another specific embodiment, the cross-section of the permeable hollow pile 32 is rectangular. Compared with the hollow pile with a circular cross-section, the rectangular permeable hollow pile 32 has a greater bearing capacity; when the surrounding soil undergoes frost heave and thaw settlement, the rectangular permeable hollow pile 32 can better protect the flexible water pipe 31 and prevent the surrounding soil from squeezing and damaging the flexible water pipe 31.

[0034] The permeable hollow piles 32 comprise a concrete layer, longitudinal steel bars 34, and pipe gallery stirrups 36. Several longitudinal steel bars 34 are arranged within the concrete layer and connected by pipe gallery stirrups 36. The vertical drainage wells 5 are also constructed from vertical steel bars 53 and drainage well stirrups 54 and poured with concrete. The structures can be connected by welding or pouring. The internal flexible water pipes 31 can be connected using an integrated connection technique of hot melt adhesive bonding and welding.

[0035] In another specific embodiment, the outer side of the flexible water pipe 31 is wrapped with a layer of aerogel felt 33, and the two are tightly connected. Filter sand 35 is filled between the inner wall of the permeable hollow pile 32 and the aerogel felt 33. The aerogel felt 33, as a thermal insulation material, can effectively prevent the accumulated water in the flexible water pipe 31 from freezing due to temperature drop, which would reduce the drainage efficiency.

[0036] In another specific embodiment, the horizontal connecting pipe 4 is positioned at a higher level near the end of the longitudinal drainage gallery 3 than near the end of the vertical drainage well 5. The horizontal connecting pipe 4 is constructed of a rigid-flexible composite material. This helps guide water in the longitudinal drainage gallery 3 into the vertical drainage well 5.

[0037] As attached Figure 3 As shown, in another embodiment, the drainage mechanism includes a pump 52 and a drainage pipe 8. Pump 52 is located at the bottom of the inner cavity of vertical drainage well 5. One end of drainage pipe 8 is connected to pump 52, and the other end extends from the upper opening of vertical drainage well 5 to connect to the channel. Thus, pump 52 and drainage pipe 8 can be used to pump water from vertical drainage well 5 into the channel as needed.

[0038] Among them, in a further embodiment based on the above, a liquid level identification sensor 51 is installed on the inner wall of the vertical drainage well 5, and a channel water level anti-overflow identifier 7 is installed at the channel mouth. The liquid level identification sensor 51 and the channel water level anti-overflow identifier 7 are electrically connected to the water pump 52 respectively.

[0039] In this way, the provision of the liquid level identification sensor 51 and the channel water level overflow prevention identifier 7 can enhance the liquid level identification function and automatic water regulation function. During use, leaked channel base water flows through the longitudinal drainage corridor 3, through the transverse connecting pipe 4, and into the vertical drainage well 5. Whenever the water level in the vertical drainage well 5 reaches a set height, the liquid level identification sensor 51 installed on the inner wall of the vertical drainage well 5 will send a signal. At this time, the wireless transmission function can transmit the signal to the pump 52, and the pump 52 will start to operate, pumping the accumulated water from the vertical drainage well 5 back into the channel. When the channel water level overflow prevention identifier 7 transmits the channel overflow signal to the pump 52, the pump 52 will not operate due to the signal from the liquid level identification sensor 51. At the same time, the water level of the accumulated water in the well can indirectly reflect the leakage status of the channel section in real time, making the entire structure more intelligent and functional. This not only saves manpower and material resources for channel maintenance, but also allows for precise maintenance and treatment of leakage within a certain section, and realizes the integration of the pumping and drainage functions of the water supply channel.

[0040] As attached Figure 5As shown, in a further embodiment based on the above, a foldable solar panel 6 is provided at the top wellhead of the vertical drainage well 5, and the solar panel 6 is electrically connected to the water pump 52 for supplying power to the water pump 52. The bottom bracket of the solar panel 6 can be fixed to the wellhead with a steel wire to achieve the connection between the two. When in use, the foldable solar panel 6 receives sunlight, and the solar energy is converted into electricity consumed by the vertical drainage well 5 to pump out the accumulated water in the well, effectively solving the problem that conventional electricity cannot be used in desert uninhabited areas; at the same time, the unfolded solar panel 6 also takes into account the insulation effect of the undrained accumulated water, in order to prevent the accumulated water in the well from freezing and being unable to be removed when the temperature is low; when pumping out water, the foldable solar panel 6 can remain in a folded state for easy construction.

[0041] In another specific embodiment, a composite lining structure 1 is further included. The channel is located on either side of the longitudinal drainage gallery 3. The composite lining structure 1 comprises, from top to bottom, a precast concrete slab, a cement mortar protective layer, and an impermeable geomembrane. In this embodiment, the seams between the precast concrete slabs can be filled with concrete. This composite lining structure 1 not only further ensures the stability of the channel structure, but also effectively guides channel water to preferentially infiltrate the longitudinal drainage gallery 3 from the bottom.

[0042] In a further embodiment based on the above, the distance between the composite lining structures 1 on both sides is gradually increased from bottom to top, thereby forming an upwardly opening flared structure that fits the channel structure.

[0043] As attached Figure 4 As shown, in a further embodiment based on the above, a concrete guide plate 2 is also included. The concrete guide plate 2 is in the shape of a rectangular column, and a wider side surface is provided with several guide grooves parallel to each other along the axial direction. The concrete guide plates 2 are symmetrically arranged below the anti-seepage geomembranes on both sides, and the upper surface of the guide groove of the concrete guide plate 2 is in contact with the lower surface of the anti-seepage geomembrane, and the bottom ends of the concrete guide plates 2 on both sides are respectively connected to the longitudinal drainage corridor 3.

[0044] In this way, through the arrangement of the concrete guide plate 2 and the guide groove thereon, water that leaks in the channel and passes through the anti-seepage geomembrane can be guided to the longitudinal drainage gallery 3, and facilitates the water to penetrate into the flexible water pipe 31 of the longitudinal drainage gallery 3, thereby preventing large-scale water seepage on the channel slope and further ensuring the long-term stability of the channel structure.

[0045] It should be noted that the terms such as "upper", "lower", "left", "right", "front", "back", etc. used in the utility model are only for the convenience of description and are not used to limit the scope of implementation of the utility model. Changes or adjustments to their relative relationships should also be regarded as the scope of implementation of the utility model without substantially changing the technical content.

[0046] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be pointed out that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should be considered within the scope of protection of the present invention.
