Abstract
Description
Technical Field
[0001] This invention belongs to the field of water conservancy engineering, specifically relating to a water intake structure for springs, its construction method, and its application. Background Technology
[0002] Traditional methods of drawing water from springs often involve constructing collection wells or pools downstream to store the water before use. While this method is relatively simple to construct, it has significant drawbacks: the spring water is completely exposed to the surface environment from the time it flows out of the spring until it enters the collection facility, making it highly susceptible to pollution from surface runoff, animal activity, vegetation decay, and human activities. This leads to a decline in water quality, requiring additional purification processes and increasing costs, which not only increases operating expenses but may also affect the natural quality of the spring water.
[0003] Furthermore, if a water intake is set directly at the spring's outlet, it will be affected by the water pressure inside the spring. Springs typically have a certain level of pressure inside, and when constructing water intake structures directly, the continuous flow of water will interfere with construction operations, increase construction difficulty, affect the seal between the structure and the spring, and may even lead to construction failure or structural instability due to water erosion. Summary of the Invention
[0004] The purpose of this invention is to provide a water intake structure, construction method, and application for springs, in order to overcome the above-mentioned technical defects.
[0005] To solve the above-mentioned technical problems, the present invention provides a water intake structure for a spring, comprising: The water intake base is located next to the outlet of the natural spring. A protective structure is provided on the upper part of the water intake base; The upstream end of the self-embedding hollow plug is used to insert into the natural spring. A telescopic pipe section is connected to the downstream end of the self-embedding hollow plug. The diversion pipe is connected to the downstream end of the telescopic pipe section and has a diversion outlet and a water intake outlet.
[0006] According to a water intake structure for a spring, the self-embedding hollow plug includes: The self-embedding hollow plug tube body has a gradually narrowing upstream end and is placed inside the protective structure at the downstream end. A flexible conical baffle is arranged circumferentially on the outer periphery of the upstream end of the self-embedding hollow plug tube body; A fastener is used to fix the flexible conical baffle to the self-embedding hollow plug tube body.
[0007] According to a water intake structure for a spring, the fixing member includes: Multiple fixing nuts are uniformly welded circumferentially to the outer wall of the gradient section at the upstream end of the self-embedding hollow plug tube; Multiple fixing bolts are threadedly connected to the fixing nuts to press and fix the flexible conical baffle.
[0008] According to a water intake structure for a spring, the diversion pipe includes: T-shaped pipe; A temporary valve is installed on the flow outlet pipe of the three-way pipe; The working valve is installed on the water intake outlet pipe of the three-way pipe.
[0009] According to a water intake structure for a spring, it also includes: Structural columns are installed below the water intake base to provide support; The sealing body has a reserved gap at the downstream top of the protective structure, and the sealing body is constructed at the reserved gap to close the reserved gap; Grouting is used to fill the gap between the self-embedded hollow plug and the natural spring.
[0010] According to a water intake structure for a spring, the system also includes a temporary fixing system during construction, which comprises: Anchor bolts are used to anchor the rock mass above the natural spring opening. A rope is connected between the anchor bolt and the piping system consisting of the self-locking hollow plug, the telescopic pipe section, and the diversion pipe.
[0011] The present invention also includes an application of a water intake structure, wherein the water intake outlet of the water intake structure is connected to a waterworks or mineral water plant through a transmission pipe for directly obtaining and transporting raw water from the natural spring.
[0012] The present invention also provides a construction method for a water intake structure for a spring, comprising the following steps: Step 100, Cleaning up the construction area: Clean the topsoil of the selected construction area; Step 200, Install a temporary diversion system: Anchor bolts were installed in the rock mass above the natural spring opening. Insert the upstream end of the self-embedding hollow plug into the natural spring and temporarily fix it with ropes and anchors; Connect and temporarily fix the downstream end of the self-embedded hollow plug, the expansion joint, and the diversion pipe in sequence; Open the temporary valve on the diversion pipe, close the working valve, and install a guide hose at the diversion pipe outlet using a circular clamp to direct the water flow to outside the construction area; Step 300, Construct the main structure: The water intake base and protective structure were constructed in sequence, and the gap between the self-embedded hollow plug and the natural spring was filled with grout. Step 400, System Conversion and Blocking: Open the working valve and close the temporary valve; Remove the diversion hoses, ropes, and anchor bolts; The construction sealing body is used to close the reserved gaps in the protective structure.
[0013] According to a construction method for a water intake structure for a spring, in step 200, the temporary fixing is achieved by connecting the anchor rod with a pipe system consisting of a self-embedded hollow plug, a telescopic pipe section, and a diversion pipe connected by flanges.
[0014] According to a construction method for a water intake structure for a spring, in step 300, when the ground outside the natural spring is lower than the spring outlet or a flat foundation cannot be provided for the water intake base, a structural column is constructed first, and then the water intake base is poured on the structural column. Step 300 further includes: The filling and grouting are carried out through grouting holes set on the protective structure.
[0015] The beneficial effects of this invention are as follows: (1) By directly inserting a self-embedded hollow plug into the spring and using a flexible conical baffle and filling grout to achieve a tight seal with the spring rock wall, a closed flow channel from the spring source to the water intake is constructed. During operation, this structure can completely isolate environmental pollution caused by surface runoff, animal and plant activities, etc., and directly obtain raw water from the source, thus maximizing the preservation of the natural quality of the spring water and eliminating the need for the post-treatment deep purification process required by traditional water collection wells.
[0016] (2) To address the inherent challenges of continuous spring flow and water pressure interference during construction, this invention utilizes a diversion pipe (especially a tee pipe) integrating temporary and working valves to form a temporary diversion system. In the initial stage of construction, the temporary diversion port is opened to divert the water flow, creating conditions for drying the work surface and ensuring the quality and safety of the main structure construction, such as concrete pouring and component installation. After the main structure is completed, the water flow can be redirected to the formal water intake channel through simple valve switching, achieving a seamless transition from the construction phase to the operational phase. This method eliminates the need for separately constructing a large diversion channel or cofferdam, reducing construction difficulty.
[0017] (3) The design of the self-embedded hollow plug, with its gradually narrowed front end and flexible conical baffle, can adapt to irregular spring shapes, achieve self-centering and compaction, and solve the sealing problem of irregular interfaces; the setting of the telescopic pipe section effectively absorbs the stress that may be caused by micro-deformation of the foundation or temperature changes during the construction and operation period, and prevents damage to the pipe system; the split design (water intake base, protective structure, optional structural column) enables the invention to flexibly adapt to various complex terrains from flat to steep, and can meet the bearing requirements of different foundation conditions by whether or not to use structural columns and adjust their parameters, and has strong versatility.

[0030] Unless otherwise stated, the terms used herein (including technical terms) have their common meaning as understood by one of ordinary skill in the art. Furthermore, it is understood that terms defined in commonly used dictionaries should be understood to have a meaning consistent with the context of their relevant field, and not to be interpreted as having an idealized or overly formal meaning.
[0031] Figure 1 , Figure 2 , Figure 7 In the image, the hollow arrow near natural spring 1 indicates the direction of water flow.
[0032] This embodiment relates to a water intake structure for springs, which enables direct, sealed, and controllable water intake from the spring source, effectively solving the problems of water quality susceptibility to pollution and water pressure interference during construction associated with traditional water intake methods. Please refer to [link / reference]. Figure 1 and Figure 2 The water intake structure includes: The intake base 2 is located beside the outlet of the natural spring 1. Specifically, the intake base 2 is positioned adjacent to the outlet of the natural spring 1. As the foundational load-bearing component of the entire water intake structure, the intake base 2's function is to evenly distribute all upper components and operational loads to the foundation, ensuring overall structural stability and reducing uneven settlement. When the outlet of the natural spring 1 is located on a steep slope or uneven terrain, the intake base 2 can be designed as an extended foundation or integrated with the lower support structure to enhance adaptability.
[0033] Among them, Natural Spring 1 is a naturally formed spring, which generally has high water quality and great development value.
[0034] When the ground outside the spring is low, the water intake base 2 is generally an enlarged rectangular foundation.
[0035] In some embodiments, the water intake base 2 is made of reinforced concrete with a strength of not less than C30.
[0036] When the ground outside the spring is low or the terrain is complex, structural columns 8 are arranged below the water intake base 2 to provide vertical and horizontal support for the water intake base 2 and to provide structural stability. The structural columns 8 adopt an integrated pile-column structure, with the bottom pile foundation penetrating into the bearing layer by no less than 2m, and the top pile top being cast integrally with the water intake base 2.
[0037] In some embodiments, the structural column 8 is made of reinforced concrete with a strength of not less than C30.
[0038] Please combine Figure 2 and Figure 3 The protective structure 3 is installed on the upper part of the water intake base 2. Specifically, the protective structure 3 is stably constructed on the upper part of the water intake base 2. As the main protective and load-bearing frame, the protective structure 3 functions to provide rigid enclosure and fixed support for the internal key water transmission pipeline system (composed of self-embedded hollow plug 4, expansion joint 5, and diversion pipe 6, etc.), resisting possible external impacts or soil loads. At the same time, a pre-reserved opening can be set at its top to facilitate later filling and sealing operations.
[0039] In some embodiments, the protective structure 3 is made of reinforced concrete with a strength of not less than C30.
[0040] The self-embedded hollow plug 4 has its upstream end directly inserted into and tightly fitted into the internal channel of the natural spring 1. The self-embedded hollow plug 4 is used to achieve water intake and sealing at the source. As the first controlled channel for spring water to flow out of the stratum, its body can guide the water flow, while its special end structure (such as a tapered design) can effectively adapt to irregular spring shapes, achieving initial sealing and water flow collection, and preventing spring water from leaking out of the pipe.
[0041] In some embodiments, the self-embedding hollow plug 4 is used to connect the flange end face of the expansion joint 5. It should be located outside the spring opening and at least 30cm away from the opening to provide sufficient operating space for subsequent pipe connection and temporary fixation.
[0042] Expansion joint 5 is connected to the downstream end of the self-locking hollow plug 4. The main function of expansion joint 5 is to provide axial displacement compensation capability, which can absorb the axial stress and displacement of the pipeline system caused by temperature changes, slight foundation deformation or construction errors, thereby avoiding excessive deformation at the rigid connection, protecting the entire pipeline system from damage, and improving the reliability and durability of the structure.
[0043] Diversion pipe 6 is connected to the downstream end of expansion joint 5. Diversion pipe 6 is the flow distribution and control hub of this water intake structure, and it has at least two outlets: a diversion outlet and a water intake outlet. During construction, the diversion outlet can be operated to divert spring water outside the construction area, creating dry construction conditions for the main structure; during operation, the water intake outlet delivers spring water to the water usage points. Diversion pipe 6 typically integrates control components such as valves, achieving a combination of construction diversion and operational water intake functions, simplifying system configuration.
[0044] The self-embedding hollow plug 4 is used to intercept and seal water intake from the natural spring 1 at its source. Its special structure ensures a tight fit and reliable seal with the irregular spring channel. The self-embedding hollow plug 4 specifically includes the following components: (1) The self-embedded hollow plug pipe body 4-1 constitutes the main load-bearing and water-guiding channel of the self-embedded hollow plug pipe 4. Its upstream end is designed as an inwardly tapered or streamlined shape. This shape facilitates smooth insertion into the irregular channel of the natural spring 1 during the insertion process, reduces resistance, and helps guide the water flow smoothly into the pipe. Its downstream end extends and is stably set in the internal space of the protective structure 3. This arrangement allows the self-embedded hollow plug pipe body 4-1 to obtain radial constraint and support from the protective structure 3, ensuring its positional stability under the action of water flow, and transferring part of the load to the overall structure.
[0045] In some embodiments, the self-embedding hollow plug tube body 4-1 is an integral hollow cylinder, made of Q235 carbon steel, with a wall thickness of not less than 10mm.
[0046] (2) The flexible conical baffle 4-2 is a sealing and anchoring element. Please refer to [link / reference]. Figure 4 The flexible conical baffle 4-2 is arranged circumferentially on the outer surface of the upstream end of the self-embedded hollow plug 4-1. When the upstream end of the self-embedded hollow plug 4-1 is inserted into the natural spring 1, the flexible conical baffle 4-2 is squeezed by the hole wall and fits tightly against the uneven rock wall or soil. Its main function is to achieve a circumferential seal between the self-embedded hollow plug 4-1 and the natural hole, effectively preventing spring water from seeping out of the gaps outside the pipe; at the same time, its conical barb structure can generate greater frictional resistance when impacted by the outward flow of water, playing a role in pull-out anchoring and limiting the displacement of the self-embedded hollow plug 4-1, thereby preventing the self-embedded hollow plug 4-1 from being pushed out by water pressure during operation.
[0047] (3) The fastener is a connecting component that ensures the flexible conical baffle 4-2 remains in its designed position on the self-embedding hollow plug tube body 4-1 without slippage or loosening. Please refer to Figure 5 The fastener consists of two sets of mating parts: (i) Multiple fixing nuts 4-3 are pre-welded securely to the designated positions on the outer wall of the upstream transition section of the self-embedded hollow plug tube body 4-1 at even intervals along the circumference. The welding method ensures that the fixing nuts 4-3 and the tube body 4-1 become an integral part, providing a rigid and precisely positioned internal thread base for the fixing bolts 4-4.
[0048] (ii) Multiple fixing bolts 4-4 correspond one-to-one with the fixing nuts 4-3 and are connected by threads. By tightening the fixing bolts 4-4, their ends can generate a continuous radial clamping force on the inner flexible conical baffle 4-2. The function of this fixing method is to reliably lock the flexible conical baffle 4-2 in the preset position of the self-embedding hollow plug body 4-1, preventing it from axially shifting due to water flow erosion or long-term vibration, thereby ensuring the durability of the sealing and anchoring effect. The bolt connection also facilitates the inspection, adjustment, or replacement of the flexible conical baffle 4-2 when necessary.
[0049] Diversion pipe 6 is a crucial component in the water intake structure, serving the dual functions of water flow guidance during construction and water intake control during operation. It cleverly solves the challenge of safe and efficient construction under the pressure of continuously flowing spring water by switching the water flow path through valves. Please refer to [link / reference]. Figure 6 The diversion pipe 6 specifically includes the following components: (1) The tee pipe 6-1 constitutes the main pipe structure of the diversion pipe 6, which is usually in the form of a T-type or Y-type tee. The function of the tee pipe 6-1 is to provide a diversion node with one inlet and two outlets. The inlet is used to receive spring water transported from the upstream expansion joint 5, while the two outlets are directed to different purposes: one as a temporary diversion outlet during construction, and the other as a permanent water intake outlet. The tee pipe 6-1 is connected to the expansion joint 5 by a flange.
[0050] In some embodiments, the tee pipe 6-1 is made of Q235 carbon steel.
[0051] (2) Temporary valve 6-2 is installed in the flow outlet pipeline of tee pipe 6-1. During the main structure construction phase, temporary valve 6-2 is in the open state. At this time, its main function is to guide most or even all of the water flow from natural spring 1 to the periphery of the construction area through this flow outlet and the connected flow hose 13. This operation creates a dry pit working environment, ensures the pouring quality of reinforced concrete components such as water intake base 2 and protective structure 3, and protects the safety of construction personnel and equipment, which is a prerequisite for the smooth implementation of the project.
[0052] (3) The working valve 6-3 is installed in the water intake outlet pipeline of the tee pipe 6-1. During construction, the working valve 6-3 is usually closed to cooperate with the temporary valve 6-2 to complete the diversion task. When the main structure is completed and needs to be put into operation, the temporary valve 6-2 is closed and the working valve 6-3 is opened. At this time, the function of the working valve 6-3 is changed to regulate the water intake flow. By adjusting the opening of the working valve 6-3, the flow of spring water to the transmission pipe 15 and finally delivered to the water plant or user can be controlled to realize water intake on demand. At the same time, this valve can also be used to cut off the upstream water source during maintenance.
[0053] Please see Figure 2 The water intake structure also includes grouting holes 7, sealing bodies 9, and filling grouting 10. These are auxiliary structures and processes used in the water intake structure to ensure overall sealing, structural integrity, and long-term stability. Together, they eliminate construction gaps, reinforce key interfaces, and complete the final closure of the structure.
[0054] Grouting hole 7 is a dedicated channel pre-installed on top of the protective structure 3 and located upstream of it. Its main function is to serve as the construction channel and operation interface for pressure grouting 10. Through grouting hole 7, construction equipment can directly pump grout to the target area. Specifically, after the self-embedded hollow plug 4 is installed and the protective structure 3 is cast, high-pressure grouting is carried out through grouting hole 7 into the gaps outside the pipe. This ensures that the filling grout 10 can fully and densely fill every designed gap, which is a necessary construction guarantee for achieving the subsequent sealing and anchoring effects.
[0055] The sealing body 9 is a structural closure component cast in the final stage of construction. Its construction presupposes that a pre-designed and constructed construction gap exists at the downstream top of the protective structure 3. This gap provides the necessary construction space and passage for equipment access, pipeline installation, and personnel operation during the main construction phase. After all internal systems are installed and commissioned, the sealing body 9 is cast at this gap. Its function is to permanently restore the integrity and continuity of the protective structure 3, transforming the temporary construction passage into a permanent structural part, thereby completely isolating the external environment and preventing surface water, impurities, or organisms from entering the water intake system, ensuring a closed and hygienic operating environment. The sealing body 9 is typically cast using micro-expansion concrete with a strength grade higher than that of the protective structure 3 itself, ensuring a tight bond between the old and new concrete and reliable load-bearing capacity.
[0056] The filling grout 10 is a special slurry material injected and solidified in the annular gap between the outer wall of the self-embedded hollow plug 4 and the inner wall of the natural spring 1. Its fundamental function is to achieve permanent consolidation and high-pressure sealing between the artificial water intake structure and the natural geological body. Specifically: First, it forms a continuous, impermeable barrier, completely blocking all potential paths for spring water to seep along the outer wall of the self-embedded hollow plug 4, forcing all water flow to be discharged only through the interior of the self-embedded hollow plug 4. This is a crucial step in ensuring the purity and lack of pollution of the water source. Second, the hardened filling grout 10 anchors the self-embedded hollow plug 4 and the surrounding rock and soil into a whole, enhancing the self-embedded hollow plug 4's resistance to water pressure impact, vibration, and pull-out, thus improving the long-term stability of the structure. Third, it plays a seepage prevention and reinforcement role in the rock and soil layers around the spring, preventing foundation softening or soil erosion caused by water seepage, and protecting the geological safety of the water intake point.
[0057] Please see Figure 7 The temporary fixing system during construction is an auxiliary facility that ensures the safe and accurate positioning of the entire pipeline system before the main permanent support structure (intake base 2, protective structure 3) has reached its full strength. Specifically, it includes: (1) Anchor bolt 11 is the foundational load-bearing component of the temporary fixing system. It is drilled at a certain angle (usually about 45° to the horizontal plane) and anchored in the stable rock or hard soil above the natural spring 1 opening. Its main function is to provide a high-strength, reliable remote anchor point. Anchor bolt 11 bears all or most of the tensile force from the entire temporary suspended pipeline system and effectively transfers and distributes these loads to the deep, stable geological body, thereby preventing the pipeline system from becoming unstable, sliding, or being washed away by water inrush due to anchor point failure.
[0058] In some embodiments, the anchor bolt 11 is a spiral steel bar anchor bolt, which is easy to remove and reuse after construction.
[0059] (2) Rope 12 is a flexible force transmission component connecting anchor 11 to the pipeline system below. Its two ends are reliably connected to the exposed end of the firmly installed anchor 11, and to the pipeline system consisting of self-embedded hollow plug 4, expansion joint 5, and diversion pipe 6 connected in series by flanges. The function of rope 12 is to provide adjustable and flexible temporary suspension and restraint for the pipeline system, which is in a suspended or open state and has not yet been permanently supported, in the early stage of construction. It allows construction personnel to make fine adjustments to the spatial position of the pipeline system within a limited range to align with the spring and the design axis; at the same time, its flexibility can buffer the instantaneous load caused by water flow impact or accidental collision, avoiding damage that may be caused by rigid connection. Rope 12 and anchor 11 together form a simple and effective force system, which maintains the spatial stability and safety of the pipeline system until the concrete of the intake base 2 and the protective structure 3 is poured and reaches sufficient strength.
[0060] In some embodiments, the rope 12 is made of synthetic fiber rope or soft steel wire rope with a tensile strength of not less than 100 kPa.
[0061] The water intake structure also includes a flow guiding hose 13, a circular clamp 14, and a transmission pipe 15. These are the pipe components that enable the water intake structure to guide water flow, provide temporary connections, and deliver water to the end user at different stages. Together, they ensure safe flow guidance during construction and reliable water resource transmission during operation.
[0062] The flow guiding hose 13 is a temporary flow guiding pipe specifically designed for the construction phase. It is specifically arranged to connect to the flow guiding outlet of the branch pipe 6 and is securely fixed to the branch pipe port on the side of the tee pipe 6-1 of the branch pipe 6. This flow guiding hose 13 is made of PVC (polyvinyl chloride) material, requiring a wall thickness of not less than 5mm. Its main function is to receive and remotely guide all spring water flowing out from the flow guiding outlet of the tee pipe 6-1 during the main structure construction. The PVC material provides it with the necessary flexibility, pressure resistance, and corrosion resistance, facilitating flexible deployment in complex construction sites and safely guiding the water flow to a designated discharge point outside the construction area, thereby creating dry construction conditions for the main structure and ensuring project safety and quality. The required wall thickness ensures sufficient structural strength under water pressure and possible external abrasion during construction.
[0063] The circular clamp 14 is a temporary fastener used to achieve a quick, reliable, and sealed connection between the flow guide hose 13 and the tee pipe 6-1. Its main function is to tightly fix and seal the end of the flow guide hose 13 to the outer wall of the branch pipe on the side of the tee pipe 6-1 through radial clamping force, preventing the connection from falling off or leaking under the pressure of the flowing water. Specialized PVC pipe clamps can be used, designed to match the pipe diameter and provide uniform clamping force; alternatively, wire can be used for temporary binding and fixing.
[0064] Transmission pipe 15 is the permanent main pipeline responsible for transporting spring water to end users after the water intake structure is put into operation. Its arrangement is as follows: one end is securely connected to the water intake outlet at the top of the tee pipe 6-1 of the branch pipe 6 via a flange, and the other end extends and connects to the water intake system of the downstream waterworks or mineral water plant. There are no specific restrictions on the type of pipe material used for transmission pipe 15.
[0065] This embodiment provides an application of a water intake structure. Specifically, the water intake outlet controlled by the working valve 6-3 of the diversion pipe 6 in the water intake structure is directly connected to the water intake system of a downstream waterworks or mineral water plant through a sealed transmission pipe 15, so as to directly obtain and transport raw water from the natural spring 1.
[0066] In this application scenario, the water intake structure has the following effects: First, as the source protection unit, it ensures that the water obtained enters a fully sealed pressure pipeline system consisting of a self-embedded hollow plug 4, a telescopic pipe section 5, a diversion pipe 6, and a transmission pipe 15 from the moment it gushes from the spring. This process completely isolates the water from all pollution along the way, such as surface runoff, animal and plant activities, and atmospheric deposition, ensuring that the water delivered to the water plant is always pristine spring water that has not been polluted by any external factors.
[0067] Secondly, as a controllable water intake unit, by operating the working valve 6-3, water plant operators can precisely adjust the water intake flow at the source according to production needs, achieving an effective balance between on-demand water supply and resource protection.
[0068] This embodiment provides a construction method for a water intake structure for a spring, including the following steps: Step 100: Clean up the construction area.
[0069] This is the primary preparatory step, and its main operation is to clear and level the surface soil, vegetation, and loose debris of the selected construction area. The function of this step is to expose a stable foundation interface, which facilitates accurate positioning and layout, prevents the collapse of unstable surface bodies or the overturning of equipment during construction, and provides clear operating space for the installation of temporary diversion systems.
[0070] Step 200: Install a temporary diversion system.
[0071] Step 201: Drill a hole in the stable rock mass above the entrance of the natural spring 1 and install anchor bolt 11. This establishes a robust, long-range load-bearing anchor point for the subsequent temporary fixing system.
[0072] Step 202: Insert the upstream end of the self-embedding hollow plug 4 into the channel of the natural spring 1, and immediately use rope 12 to temporarily connect and fix it to the installed anchor rod 11. This operation initially achieves the collection and constraint of the water outlet.
[0073] Step 203: At the downstream end of the self-embedding hollow plug 4, connect the expansion joint 5 and the diversion pipe 6 in sequence, and temporarily fix the entire series pipe system to the anchor bolt 11 with rope 12. At this point, the temporary water conveyance channel from the spring to the diversion point is completed.
[0074] Temporary fixation is achieved by connecting the anchor rod 11 with the piping system consisting of the self-embedded hollow plug 4, the expansion joint 5, and the diversion pipe 6 via flanges using rope 12.
[0075] Step 204, switch the water flow: Open the temporary valve 6-2 on the diversion pipe 6, while ensuring that the working valve 6-3 is closed. At this time, the spring water flow is forcibly diverted and flows out through the temporary valve 6-2. At the diversion outlet of the diversion pipe 6, use the circular clamp 14 to quickly install and fix the diversion hose 13, remotely diverting the water flow outside the construction area. After this step is completed, the construction area of the main structure is in a dry or basically dry state.
[0076] Step 300: Construct the main structure.
[0077] The intake base 2 and the protective structure 3 are poured sequentially. The construction of the intake base 2 provides a permanent and stable foundation for the entire structure; the pouring of the protective structure 3 forms a rigid outer shell protecting the internal piping system. Simultaneously or after the construction of the protective structure 3, grout is injected 10 through the pre-reserved grouting holes 7 into the annular gap between the outer wall of the self-embedded hollow plug 4 and the wall of the natural spring 1. This process achieves a permanent seal and consolidation between the intake pipe and the geological body, which is crucial for ensuring the long-term seepage prevention and stability of the structure.
[0078] When the ground outside the natural spring 1 is low or the terrain is complex, that is, when the ground outside is much lower than the spring outlet or cannot provide a flat foundation for the water intake base 2, the structural column 8 is constructed first, and then the water intake base 2 is poured on the structural column 8.
[0079] Step 400: System conversion and blocking.
[0080] Step 401: Permanently switch the water flow path: Open the working valve 6-3 and simultaneously close the temporary valve 6-2. At this point, the spring water flow officially enters the permanent water intake channel controlled by the working valve 6-3, leading to the transmission pipe 15.
[0081] Step 402, dismantle all temporary auxiliary facilities: dismantle the flow guide hose 13, rope 12 and anchor bolt 11 in sequence. The dismantling will not affect the operation of the permanent structure.
[0082] Step 403: Final closure of the structure: Pour sealing material 9 at the construction gap reserved on the protective structure 3. This permanently closes the construction passage, restoring the protective structure 3 to a complete, sealed protective shell, completely isolating it from the external environment.
[0083] This embodiment relates to a water intake structure and construction method for a spring, and its application. On one hand, by utilizing a three-way pipe combined with a temporary valve and a working valve, water flow can be effectively diverted and water pressure at the spring can be reduced during the construction phase. This provides safe and dry working conditions for structural construction, avoiding the need for separate construction of diversion channels, cofferdams, and other temporary pressure-reducing facilities in traditional methods. This significantly simplifies the construction process, shortens the construction period, and reduces project construction costs. On the other hand, through the tight sealing combination of a self-embedded hollow plug and the spring, coupled with a fully enclosed pipeline transportation system, direct water intake from the spring source is achieved. During operation, this structure can completely isolate surface pollutants, biological activity, and external environmental interference with water quality, ensuring the purity and stability of the water intake.
[0084] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of the present invention.
