Description

Technical Field

[0001] This invention relates to the field of barrier wall construction technology, and more specifically to a device for constructing a pollutant barrier wall. Background Technology

[0002] Wastewater barrier walls can effectively prevent wastewater from entering clean water bodies, prevent the spread of pollutants, and protect the water environment, especially near pollution sources such as factories and agricultural production areas. Wastewater barrier walls can effectively control wastewater leakage and prevent pollution of groundwater and rivers.

[0003] The existing barrier wall materials and construction methods are formulated according to the actual site conditions. Among them, the method of grouting inside the barrier bag is a relatively convenient construction method in the current barrier wall construction. The barrier bag body is made of double-layer impermeable material and is filled with mixed grout, which causes the barrier bag to expand and form a barrier wall.

[0004] In existing grouting construction methods, the grout needs to be mixed on-site before grouting. During the grouting process, it is necessary to maintain the continuity of grouting and reduce the formation of cavities by air entering the barrier bag. However, the current construction method usually involves mixing the grout, letting it stand, and then grouting it. This waiting time causes the grouting to be discontinuous, which can easily lead to the formation of air cavities in the grouting pipe. As subsequent grout enters the barrier bag, cavities will form inside the barrier bag, affecting the barrier wall's barrier effect. Therefore, technical optimization of the construction device is necessary. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve:

[0006] To address the problem that intermittent grouting during the construction of existing barrier walls can easily lead to the formation of cavities inside the barrier bags, this invention provides a pollutant barrier wall construction device. By alternately connecting a directional conveying component with each feed pipe, it achieves the effect of alternating and continuous grouting.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0009] A pollutant barrier wall construction device includes a support frame, and a conveying pipe assembly and a feeding pipe assembly, both vertically mounted on the support frame. The conveying pipe assembly includes a main conveying pipe and a collecting pipe, with the collecting pipe connected to the bottom of the support frame and the main conveying pipe connected to the top of the collecting pipe. The bottom wall of the main conveying pipe has outlet ports spaced apart. The feeding pipe assembly includes feeding pipes, each vertically and evenly surrounding the main conveying pipe. The outlet ports are alternately connected to each feeding pipe via a directional conveying assembly. Each feeding pipe is connected to the collecting pipe. The main conveying pipe is connected to a slurry conveying machine via a feeding conduit, and the collecting pipe is connected to a barrier bag via a discharge conduit. The outlet ports, through the directional conveying assembly and the alternately connected feeding pipes, discharge material to the collecting pipe, thereby achieving the purpose of alternating and continuous grouting into the barrier bag.

[0010] A further technical solution involves three feed pipes: a first feed pipe, a second feed pipe, and a third feed pipe. These three feed pipes work alternately and collaboratively, under the directional conveying action of the directional conveying assembly:

[0011] When the first feed pipe is in a slurry-filled state, i.e., an external feed state, the slurry inside the third feed pipe fills the barrier bag, while the slurry inside the second feed pipe is in a static, venting state.

[0012] When the second feed pipe is in the external feeding state, the slurry inside the third feed pipe is in the static venting state. At this time, the slurry inside the first feed pipe fills the barrier bag.

[0013] When the first feed pipe is filled with slurry, the slurry in the third feed pipe is filling the barrier bag, while the slurry in the second feed pipe is in a static venting state. The main conveying pipe alternately feeds the three parts, realizing the continuity of feeding, filling and venting, and achieving the purpose of preventing air from entering the interior of the barrier bag and forming a cavity.

[0014] A further technical solution includes a conveying ring sleeved on the outer side of the bottom of the main conveying pipe; the directional conveying assembly includes a conveying conduit corresponding to and connected to each feed pipe, the input end of the conveying conduit being adapted to the position of the discharge port, a partition plate being vertically inserted inside the conveying conduit, and a first sliding rod being vertically fixed on both sides of the conveying conduit; the two sides of the partition plate are sleeved on the first sliding rod, and a first spring is sleeved on the first sliding rod with the sleeve point facing downward, so as to realize the alternating opening and closing of the discharge port by each partition plate.

[0015] A further technical solution also includes a guide component for guiding the directional conveying components to alternately convey direction; the guide component includes a guide collar connected to the top outer side of the main conveying pipe, a guide groove is provided at the bottom of the guide collar, a second annular limiting groove is provided at the top of the guide collar, a first limiting groove is provided vertically downward and communicates with the second limiting groove; a third limiting groove is provided obliquely upward at the bottom end of the first limiting groove and communicates with the second limiting groove. The guide component with the special structure can realize the alternating action of each partition plate.

[0016] A further technical solution also includes a directional pushing component adapted to the guiding component; the directional pushing component includes a movable plate, a stop block, a second spring, and a second slide rod; the feed pipe wall near the guide collar is provided with a movable through hole, one end of the stop block passes through the movable plate and slides up and down in the movable through hole, and the other end is embedded with a sliding ball, which is tumblingly connected in the first limiting groove, the second limiting groove, and the third limiting groove; the outer wall of the feed pipe is provided with a slot adapted to the movable plate, and the top of the feed pipe is connected to the second slide rod at the position on both sides of the movable plate, both sides of the movable plate are sleeved on the body of the second slide rod, and the second slide rod body with the sleeve point facing downward is sleeved with a second spring. The directional pushing component and the guiding component work together to achieve the effect of alternating action on each partition plate while also achieving alternating reset.

[0017] A further technical solution involves a movable connecting rod connected to the top of the partition plate, with a ball embedded in the top of the movable connecting rod. The top of the ball is connected to the bottom of the guide collar. Combined with the guide groove at the bottom of the guide collar, the partition plate is subjected to alternating lifting and resetting action, thus achieving automated operation.

[0018] A further technical solution is that the third limiting groove is an arc-shaped groove structure, and the groove depth of the third limiting groove gradually decreases from the end near the first limiting groove to the end near the second limiting groove. The groove depth of the third limiting groove is the same at the end near the second limiting groove. The groove depth of the first limiting groove and the second limiting groove are the same. The angle between the two ends of the third limiting groove when viewed from above is 120°. Each limiting groove works in conjunction with the sliding ball to realize the automatic rotation of the guide collar, thereby driving the lifting and resetting of the movable connecting rod.

[0019] A further technical solution involves a pressure plate that slides vertically along the inner wall of the feed pipe. Slider blocks are evenly distributed along the outer edge of the pressure plate, and the inner wall of the feed pipe is provided with a sliding groove that matches the slider. When the pressure plate rises to the position of the movable through hole, a stop block presses against the surface of the pressure plate. The pressure plate is raised and lowered by the filling and emptying of the slurry, which in turn drives the sliding ball to roll and starts the automatic rotation of the guide collar.

[0020] A further technical solution is that the bottom of each feed pipe is equipped with a hopper that extends to the bottom of the support frame. The bottom output end of each hopper is equipped with a guide pipe that communicates with the bottom of the collection pipe. An electric control valve is installed in the middle of each guide pipe to realize the alternating opening and closing of each guide pipe.

[0021] A further technical solution involves installing an electric control switch on the outer wall of the feed pipe near the conveying conduit, and installing a pressure block corresponding to the electric control switch on the top of the partition plate; the electric control switch is electrically connected to the adjacent group of electric control valves to achieve automatic alternating on and off.

[0022] 3. Beneficial effects

[0023] Compared with the prior art, the technical solution provided by this invention has the following advantages:

[0024] The pollutant barrier wall construction device of the present invention forms a continuous grouting body by setting up multiple feed pipes. When one group is grouting the barrier bag, the grout inside another group is in a static waiting state, while the last group is in an external feeding state. Through the alternating circulation of each feed pipe, the continuity of feeding, grouting and static venting is achieved. At the same time, a pressure plate is set inside, and grouting is carried out from the bottom through a conveying conduit, so that air at the top will not enter the interior of the feed pipe. Furthermore, the vertical displacement of the pressure plate drives the alternating circulation of the feed pipes to achieve structural continuity. Attached Figure Description

Detailed Implementation

[0044] To further understand the content of this invention, a detailed description of the invention is provided in conjunction with the accompanying drawings.

[0045] Example 1

[0046] The pollutant barrier wall construction device of this embodiment, such as Figure 1 , 2As shown, the system includes a support frame 100, and also includes a conveying pipe assembly 300 and a feed pipe assembly 200, both vertically mounted on the support frame 100. The conveying pipe assembly 300 includes a main conveying pipe 301 and a collecting pipe 303. The collecting pipe 303 is connected to the bottom of the support frame 100, and the main conveying pipe 301 is connected to the top of the collecting pipe 303. Figure 9 As shown, the bottom wall of the main conveying pipe 301 is provided with discharge ports 16 at intervals; the feed pipe assembly 200 includes feed pipes, each feed pipe is vertically and evenly wrapped around the periphery of the main conveying pipe 301, forming a structure in which the main conveying pipe 301 is in the center and each feed pipe is on its periphery. Each discharge port 16 is alternately connected to each feed pipe through the directional conveying assembly 700. Each feed pipe is connected to the collecting pipe 303 through a pipe. The main conveying pipe 301 is connected to the conveying slurry machine through the feed conduit 500, and the collecting pipe 303 is connected to the barrier bag through the discharge conduit 600.

[0047] In this embodiment of the pollutant barrier wall construction device, each discharge port 16 is alternately connected to each feed pipe through the directional conveying component 700 to discharge material to the collection pipe 303, thereby achieving the purpose of alternating and continuous grouting to the barrier bag.

[0048] Example 2

[0049] The pollutant barrier wall construction device of this embodiment has the same basic structure as that of Embodiment 1, except that there are three feed pipes: a first feed pipe 201, a second feed pipe 202, and a third feed pipe 203; under the directional alternating conveying action of the directional conveying assembly 700:

[0050] When the first feed pipe 201 is in a slurry-filled state, i.e., an external feed state, the slurry inside the third feed pipe 203 fills the barrier bag, while the slurry inside the second feed pipe 202 is in a static venting state.

[0051] When the second feed pipe 202 is in the external feeding state, the slurry inside the third feed pipe 203 is in the static venting state. At this time, the slurry inside the first feed pipe 201 fills the barrier bag.

[0052] When the first feed pipe 201 is in a slurry-filled state, the slurry inside the third feed pipe 203 fills the barrier bag, while the slurry inside the second feed pipe 202 is in a static, venting state.

[0053] The pollutant barrier wall construction device of this embodiment uses a main conveying pipe 301 to alternately feed three components: the first feed pipe 201, the second feed pipe 202, and the third feed pipe 203, which form the main body of continuous grouting. When one group is grouting the barrier bag, the grout inside the other group is in a static waiting state, while the last group is in an external feeding state. Through the alternating cycle of the three components, the continuity of grouting and static venting is achieved. Furthermore, by grouting the bottom of the three components, air from the top will not enter the interior of the three components. The alternating cycle of the three components ensures the continuity of the structure.

[0054] Example 3

[0055] The pollutant barrier wall construction device in this embodiment has the same basic structure as in embodiment 2, but the differences or improvements are as follows: Figure 9 , 10 As shown, the conveying pipe assembly 300 also includes a conveying ring 302 sleeved on the outer side of the bottom of the main conveying pipe 301; the directional conveying assembly 700 includes a conveying conduit 701 that corresponds to and is connected to each feed pipe. The input end of the conveying conduit 701 is adapted to the position of the discharge port 16. The main conveying pipe 301 is provided with three sets of discharge ports 16 and connecting posts 18 at intervals inside the conveying ring 302, which are adapted to the three conveying conduits 701 and correspond to the three feed pipes.

[0056] like Figure 9 , 10 As shown, a partition plate 702 is vertically inserted inside the conveying conduit 701, and a first slide rod 703 is vertically fixed on both sides of the conveying conduit 701; the two sides of the partition plate 702 are sleeved on the first slide rod 703, and a first spring 704 is sleeved on the first slide rod 703 with the sleeve point facing downward, so as to realize the alternating opening and closing of the discharge port 16 by each partition plate 702.

[0057] It also includes a guide component 400 for the directional and alternating conveying of the directional conveying component 700; such as Figure 3 , 8 As shown, the guide assembly 400 includes a guide collar 401 connected to the outer side of the top of the main conveying pipe 301. The bottom of the guide collar 401 is provided with a guide groove 402, and the top of the guide collar 401 is provided with an annular second limiting groove 404. The second limiting groove 404 is vertically arranged downward and communicates with a first limiting groove 403. The bottom end of the first limiting groove 403 is obliquely arranged upward and communicates with the second limiting groove 404. The guide assembly with the special structure can realize the alternating action on each partition plate 702.

[0058] It also includes a directional actuation component 800 that is compatible with the guide component 400; such as Figure 4 , 5As shown in Figures 6 and 7, the directional pushing assembly 800 includes a movable plate 801, a stop block 803, a second spring 805, and a second slide rod 806; the feed pipe wall near the guide collar 401 is provided with a movable through hole 802, one end of the stop block 803 passes through the movable plate 801 and slides up and down in the movable through hole 802, and the other end is fitted with a sliding ball 804, which is tumbled and connected in the first limiting groove 403, the second limiting groove 404, and the third limiting groove 405; The outer wall of the feed pipe is provided with a slot 807 that matches the movable plate 801. The top of the feed pipe is connected to the second slide rod 806 at the position on both sides of the movable plate 801. Both sides of the movable plate 801 are sleeved on the rod body of the second slide rod 806. The rod body of the second slide rod 806 with the sleeve point facing downward is sleeved with a second spring 805. The directional pushing component 800 and the guide component 400 work together to achieve the effect of alternating action on each partition plate 702 while also achieving the effect of alternating reset.

[0059] like Figure 7 , 8 As shown in Figures 9, 10, and 11, a movable connecting rod 14 is connected to the top of the partition plate 702. A ball bearing 15 is embedded in the top of the movable connecting rod 14. The top of the ball bearing 15 is connected to the bottom end of the guide collar 401. Combined with the guide groove 402 at the bottom end of the guide collar 401, the partition plate 702 is subjected to alternating lifting and resetting action, thereby achieving automated operation.

[0060] The third limiting groove 405 is an arc-shaped groove structure, and the groove depth of the third limiting groove 405 gradually decreases from the end near the first limiting groove 403 to the end near the second limiting groove 404. The groove depth of the third limiting groove 405 at the end near the second limiting groove 404 is the same. The groove depth of the first limiting groove 403 and the second limiting groove 404 is the same. The angle between the two ends of the third limiting groove 405 when viewed from above is 120°. Each limiting groove and the sliding ball 804 cooperate to realize the automatic rotation of the guide collar 401, thereby driving the lifting and resetting of the movable connecting rod 14.

[0061] The inner walls of the three feed pipes are all slidably connected to pressure plates 21. Slider 19s are evenly arranged on the outer edge of the pressure plates 21, and the inner walls of the feed pipes are provided with sliding grooves 20 that are compatible with the slider 19s. When the pressure plates 21 rise to the position of the movable through hole 802, the stop block 803 presses against the surface of the pressure plates 21. The pressure plates 21 are raised and lowered by the filling and emptying of the slurry, which in turn drives the sliding ball 804 to roll and starts the automatic rotation of the guide collar 401.

[0062] The bottom of each of the three feed pipes is provided with a feeding hopper 10 that extends through to the bottom of the support frame 100. The bottom output end of each feeding hopper 10 is provided with a guide pipe 11 that communicates with the bottom of the collecting pipe 303. An electric control valve 12 is provided in the middle of each guide pipe 11 to realize the alternating opening and closing of each guide pipe 11.

[0063] An electric control switch 13 is installed on the outer wall of each of the three feed pipes near the conveying conduit 701. A pressure block 17 corresponding to the electric control switch 13 is installed on the top of the partition plate 702. The electric control switch 13 is electrically connected to the adjacent set of electric control valves 12. When the first feed pipe 201 is in a slurry-filled state, the slurry in the third feed pipe 203 is in a released state, while the slurry in the second feed pipe 202 is in a static venting state, thus realizing automatic alternating on and off.

[0064] The usage process of the pollutant barrier wall construction device proposed in this embodiment is as follows: When the device is in use, it is connected to the feed pipe 500 through an external pipe, thereby transporting the grout to be grouted to the inside of the main conveying pipe 301. The grout is then alternately transported through the main conveying pipe 301 to the inside of the first feed pipe 201, the second feed pipe 202, and the third feed pipe 203, and further transported through the discharge hopper 10 to the inside of the collection pipe 303. The grout is then injected into the barrier bag through the discharge pipe 600 connected to the collection pipe 303, thereby completing the grouting operation of the barrier wall.

[0065] When the device is in use, the slurry inside the main feed pipe 301 is transported to the inside of the first feed pipe 201 through the feed conduit 701 connected to the first feed pipe 201. The pressure of the transported slurry drives the pressure plate 21 to move upward. As the amount of slurry inside the first feed pipe 201 increases, the pressure plate 21 moves upward continuously. At this time, the second feed pipe 202 and the third feed pipe 203 are in an empty waiting state.

[0066] like Figure 5 , 6 As shown, as the pressure plate 21 rises continuously, it presses upward against the stop block 803 inside. The upward force of the pressure plate 21 drives the stop block 803 to move upward, which in turn drives the movable plate 801 to move upward as a whole. As the stop block 803 moves upward, the sliding ball bearings 804 move on the guide collar 401. At this time, the sliding ball bearings 804 on the first feed pipe 201 are located inside the third limiting groove 405 and move upward from the bottom of the third limiting groove 405, which in turn drives the guide collar 401 to rotate. At this time, the two sets of sliding ball bearings 804 on the second feed pipe 202 and the third feed pipe 203 are located inside the second limiting groove 404. When the sliding ball bearings 804 on the first feed pipe 201 move to the top of the third limiting groove 405 and connect to the inside of the second limiting groove 404, the guide collar 401 rotates 120° as a whole.

[0067] During this process, the rotation of the guide collar 401 drives the rotation of the guide groove 402. The rotation of the guide groove 402 causes the movable connecting rod 14 near the first feed pipe 201 to be squeezed downward by the guide groove 402. In turn, the movable connecting rod 14 drives the partition plate 702 to move downward. When the guide collar 401 rotates 120°, the conveying conduit 701 near the first feed pipe 201 is blocked by the partition plate 702, and the feeding into the first feed pipe 201 stops.

[0068] As the guide collar 401 rotates 120°, the guide groove 402 moves to a position close to the third feed pipe 203. At this time, the first spring 704 near the third feed pipe 203 rebounds upward, causing the movable connecting rod 14 connected to the partition plate 702 to move upward into the guide groove 402. This opens the passage of the conveying conduit 701 near the third feed pipe 203, allowing the slurry inside the main conveying pipe 301 to enter the third feed pipe 203. At this time, the slurry inside the first feed pipe 201 is in a static venting state, while the third feed pipe 203 is in a feeding state.

[0069] As the partition plate 702 near the third feed pipe 203 moves upward, it causes the pressure block 17 to move upward, thereby squeezing the electric control switch 13 on the outside of the third feed pipe 203. The electric control switch 13 controls the opening of the electric control valve 12 connected to the bottom guide pipe 11 of the second feed pipe 202. At this time, the inside of the second feed pipe 202 is empty, so the barrier bag will not be filled with grout.

[0070] Simultaneously, as the guide collar 401 rotates 120°, the sliding ball 804 near the third feed tube 203 slides down through the first limiting groove 403 to the bottom of the third limiting groove 405. Since the bottom groove of the third limiting groove 405 is deeper than the first limiting groove 403, the sliding ball 804 is limited.

[0071] As material is fed into the third feed pipe 203, the pressure plate 21 inside the third feed pipe 203 also moves upward continuously. When the pressure plate 21 also presses the stop block 803 at its top, it also drives the sliding ball 804 to move upward, causing the guide ring 401 to rotate. As the guide ring 401 rotates, the movable connecting rod 14 near the position of the third feed pipe 203 is squeezed by the bottom of the guide ring 401 and moves downward, thereby causing the partition plate 702 to close the conveying conduit 701.

[0072] When the guide collar 401 rotates 120° again, the movable connecting rod 14 near the second feed pipe 202 is subjected to the rebound force of the first spring 704 at its bottom, which opens the passage of the conveying conduit 701 near the second feed pipe 202 and closes the passage of the conveying conduit 701 near the third feed pipe 203, thereby feeding the second feed pipe 202.

[0073] Meanwhile, the partition plate 702 near the second feed pipe 202 moves upward, causing the pressure block 17 to move upward until it is in contact with the electric control switch 13. Then, the electric control switch 13 controls the opening of the electric control valve 12 connected to the bottom of the first feed pipe 201, opening the passage of the guide pipe 11. This allows the slurry that has been settled inside the first feed pipe 201 to be transported to the collection pipe 303. Then, the discharge pipe 600 is used to grout the external barrier bag. As the slurry is fed into the second feed pipe 202 and the slurry in the third feed pipe 203 is settled and vented, the construction device forms an intermittent circulating feeding function, which improves the construction efficiency, reduces the entry of air, and thus ensures the construction quality of the barrier wall.

[0074] In this embodiment of the pollutant barrier wall construction device, three feed pipes form the main body of continuous grouting. While one group is grouting the barrier bag, the grout inside another group is in a static waiting state, and the last group is in an external feeding state. Through the alternating cycle of the three, the continuity of grouting and static venting is achieved. At the same time, a pressure plate 21 is set inside. Grouting is carried out from the bottom of the three through the conveying pipe 701, so that air at the top will not enter the interior of the three. Furthermore, the vertical displacement of the pressure plate 21 drives the alternating cycle of the three to achieve structural continuity. While grouting is carried out continuously without intervals, as subsequent grout continues to enter the interior of the barrier bag, no air cavity is formed in the grouting pipe after static venting, thereby improving the barrier wall's barrier effect.

[0075] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
