Description

Technical Field

[0001] This utility model relates to the fields of water conservancy and environmental engineering, specifically a gravel cage retaining wall device that can recycle and collect silt. Background Technology

[0002] Dredging and management projects of rivers, lakes, and reservoirs generate large amounts of high-water-content silt, which often needs to be stored and reduced on-site before being transported and utilized for resource recovery. In silt storage projects, early tailings dams and similar structures are rarely used as silt storage systems due to their high construction costs and the need to utilize natural valleys or depressions as silt reservoirs, placing high demands on site conditions. Constructing embankments to store silt can solve the problem of the lack of valleys or depressions in the near-shore areas of rivers, lakes, and reservoirs, but it is generally less used due to its poor durability and stability, and significant construction safety hazards. In recent years, both domestically and internationally, bag dams or dikes constructed by filling strip-shaped tubular bags with silt or sand have been used for silt storage. This type of engineering structure has advantages such as permeability, soil retention, convenient construction, and relatively low cost.

[0003] A search of publicly available patent CN118911196A reveals a sludge-collecting device using a crushed stone cage retaining wall, a circular retaining wall system for collecting sludge, and a construction method thereof. The sludge-collecting system comprises a circular retaining wall formed by stacking multiple layers of circular crushed stone cages from bottom to top, a drainage ditch, a purification treatment tank, a water intake channel, and an isolation layer. The inner circumference of the circular retaining wall forms a space for containing sludge. The cross-sectional diameter of each circular crushed stone cage decreases sequentially from bottom to top, making the radial longitudinal section profile of the circular retaining wall trapezoidal. A drainage ditch is installed on the ground around the perimeter of the circular retaining wall. After the sludge inside the circular retaining wall is filtered by the filter layer on the inner wall of the circular crushed stone cage, the discharged sludge flows into the drainage ditch. The drainage ditch is connected to the purification treatment tank via the water intake channel. The isolation layer is used to isolate the sludge and sludge from the ground / underground surface. The silt storage system provided in this application has strong stability, can achieve efficient drainage of the stored silt, is simple to construct, and is environmentally friendly. In the aforementioned prior art, the silt has a relatively low seepage rate during the static process, and the silt cannot quickly clump together, resulting in a long single silt storage cycle. Secondly, existing silt storage systems are disposable and inconvenient to reuse. Removing clumps of silt requires dismantling the gravel retaining wall, which is time-consuming, labor-intensive, and costly. Utility Model Content

[0004] The purpose of this utility model is to provide a gravel cage retaining wall device that can recycle and collect silt in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slag cage retaining wall device for cyclically collecting silt, comprising a slag cage wall, which is a frustum-shaped structure with open ends and hollow interior, and the radial longitudinal section profile of the slag cage wall is a right trapezoidal structure.

[0006] The inner wastewater pool has a ring-shaped groove structure and is located on the ground at the bottom of the rubble frame cage wall.

[0007] A cylindrical section is located inside the rubble cage enclosure wall, and the outer wall of the cylindrical section has multiple evenly distributed small holes. The outer side of the cylindrical section is fitted with rubble cage wall columns that are aligned with the same length as the cylindrical section. The upper end of the rubble cage wall columns is sealed with a cover plate, and the lower end of the cylindrical section is sealed with a bottom plate. The middle of the cover plate has an air extraction hole, and the upper surface of the cover plate is fixedly connected with a track with an "I" shaped cross section by bolts.

[0008] The lifting seat, in the form of a ring, is located between the crushed stone cage wall and the crushed stone cage wall column. The lifting seat has multiple evenly distributed through holes. The crushed stone cage wall, the lifting seat, and the crushed stone cage wall column together form a space for accommodating the silt to be treated. The inner wall of the crushed stone cage wall, the outer wall of the crushed stone cage wall column, and the upper surface of the lifting seat are all covered with a filter layer.

[0009] The lifting seat control system is located between the lifting seat and the track. When the silt in the silt storage space formed by the crushed stone cage wall, the lifting seat and the crushed stone cage wall column clumps together, the lifting seat control system drives the lifting seat to rise and remove the clumped silt from the silt storage space.

[0010] As a further embodiment of this utility model: both the rubble cage wall and the rubble cage wall column are filled with rubble, and the top position of the rubble cage wall column is relatively higher than the top position of the rubble cage wall.

[0011] As a further embodiment of this utility model: an isolation layer is laid on the bottom of the inner wastewater pool, the bottom of the outer wastewater pool, and the ground between the inner wastewater pool and the outer wastewater pool, and the isolation layer is an impermeable geomembrane.

[0012] As a further improvement of this utility model, the filter layer is a geotextile.

[0013] As a further improvement of this utility model: the lifting seat is made of hard steel plate, and four hanging ears are evenly distributed in a ring on the top of the lifting seat, and the hanging ears are fixedly connected to the lifting seat by welding.

[0014] As a further embodiment of this utility model: the upper end of the inner wastewater tank is connected to an air extraction pipe, which is connected to an external air pump for drawing air from the inner wastewater tank to create negative pressure in the inner wastewater tank. The lower end of the inner wastewater tank is connected to a first water extraction pipe, one end of which is connected to an external water pump. An electrically controlled valve is installed on the first water extraction pipe to cooperate with the external pump to control the first water extraction pipe to extract the wastewater accumulated in the inner wastewater tank.

[0015] As a further improvement of this utility model: the outer end of the external wastewater pool is connected to a second pumping pipe, which is connected to an external pumping pump for pumping out the wastewater accumulated in the external wastewater pool.

[0016] As a further embodiment of this utility model: the lifting seat control system includes a winch, four sets of pulleys and four steel cables installed above the cover plate. The winch and the four sets of pulleys are detachably installed on the track. The four sets of pulleys are distributed in a ring at equal intervals around the cover plate, and the winch is located between the four sets of pulleys.

[0017] Each of the four pulley groups has a steel cable wound around it. One end of the steel cable is wound around the winding end of the winch, and the other end of the steel cable is tied to the lug.

[0018] As a further improvement of this utility model: an air pump is installed on the top of the cover plate, and the input end of the air pump is adapted to be connected to the air extraction hole in the middle of the cover plate for sucking air from the cylinder to create a negative pressure inside the cylinder.

[0019] As a further embodiment of this utility model: a sealing layer is provided on the upper inner wall of the rubble cage wall column, and the lower end of the sealing layer is lower than the top of the rubble cage wall, and the sealing layer is a sealing film.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By designing the inner wall of the rubble cage retaining wall as a straight surface, and balancing the lateral tilting force of the inner ring surface with the lateral pressure of the silt, the structure is reasonable and highly stable. The top of the rubble cage retaining wall is equipped with a lifting seat control system, which can realize the integrated function of silt storage and rapid removal of silt in the ring after silt storage by controlling the lifting seat control system without dismantling the rubble cage retaining wall. This allows the silt storage retaining wall to be reused during the project construction period.

[0022] 2. The lifting platform control system and cover plate design are flexible. Both the winch and pulley block in the lifting platform control system are detachable and can be reassembled and installed according to project needs, meeting the requirements of most projects.

[0023] 3. The combination of the cylinder, lifting plate, and air pump creates a near-vacuum environment, structurally increasing the drainage area and drainage rate. Simultaneously, the presence of the lifting seat control system allows the lifting seat and filter layer to be removed sequentially for flushing and cleaning before reuse in secondary siltation projects. This prevents silt accumulation in the lifting seat's through-holes and inside the filter layer after the previous siltation and drainage process from affecting subsequent silt drainage. Furthermore, any silt that may remain on the air vents of the extraction pipe can be blown out by the air pump, greatly minimizing the impact on the drainage rate during secondary siltation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5In this embodiment of the utility model, a slag cage retaining wall device for cyclically collecting silt includes a slag cage wall 1, which is a frustum-shaped structure with open ends and hollow interior, and the radial longitudinal section profile of the slag cage wall 1 is a right trapezoidal structure.

[0032] The inner wastewater pool 2 has a ring-shaped groove structure and is located on the ground at the bottom of the rubble frame cage wall 1. The inner wastewater pool 2 is located below the lower opening end of the rubble frame cage wall 1, and the outer wastewater pool 4 is located on the ground around the outer perimeter of the rubble frame cage wall 1.

[0033] A cylindrical tube 6 is located inside the rubble cage wall 1, and the outer wall of the cylindrical tube 6 has a number of evenly distributed small holes. The outer side of the cylindrical tube 6 is fitted with rubble cage wall columns 3 that are aligned with the same length as the cylindrical tube 6. The upper end of the rubble cage wall column 3 is sealed with a cover plate 61, and the lower end of the cylindrical tube 6 is sealed with a bottom plate 62. The middle part of the cover plate 61 has an air extraction hole 611, and the upper surface of the cover plate 61 is fixedly connected with a track 63 with an "I" cross-section by bolts.

[0034] The lifting seat 5 has a circular structure and is located between the crushed stone cage wall 1 and the crushed stone cage wall column 3. The lifting seat 5 has multiple evenly distributed through holes. The crushed stone cage wall 1, the lifting seat 5 and the crushed stone cage wall column 3 together form a space for accommodating the silt to be treated. The inner wall of the crushed stone cage wall 1, the outer wall of the crushed stone cage wall column 3 and the upper surface of the lifting seat 5 are all covered with a filter layer 7, which is a geotextile.

[0035] The lifting seat control system 8 is located between the lifting seat 5 and the track 63. When the silt in the silt storage space formed by the crushed stone cage wall 1, the lifting seat 5 and the crushed stone cage wall column 3 clumps together, the lifting seat control system 8 drives the lifting seat 5 to rise and remove the clumps of silt from the silt storage space.

[0036] Both the rubble cage wall 1 and the rubble cage wall column 3 are filled with rubble blocks, and the top of the rubble cage wall column 3 is relatively higher than the top of the rubble cage wall 1; the lifting seat 5 is made of hard steel plate, and four hanging ears 51 are evenly distributed in a ring on the top of the lifting seat 5. The hanging ears 51 are fixedly connected to the lifting seat 5 by welding.

[0037] The lifting seat control system 8 includes a winch 801, four sets of pulley blocks 802 and four steel cables 803 installed above the cover plate 61. The winch 801 and the four sets of pulley blocks 802 can be detachably installed on the track 63. The four sets of pulley blocks 802 are distributed in a ring at equal intervals around the cover plate 61, and the winch 801 is located between the four sets of pulley blocks 802.

[0038] Each of the four pulley blocks 802 has a steel cable 803 wound around it. One end of the steel cable 803 is wound around the winding end of the winch 801, and the other end of the steel cable 803 is tied to the lug 51.

[0039] In this embodiment: by designing the inner wall of the crushed stone cage retaining wall 1 as a straight surface, and balancing the lateral tilting force of the inner ring surface with the lateral pressure of the silt, the structure is reasonable and has high stability; and by setting up a lifting seat control system 8, the silt can be collected and the silt can be removed directly by lifting the lifting seat 5 without dismantling the crushed stone cage retaining wall 1, so that the silt-collecting retaining wall can be reused within the construction period.

[0040] Specifically, when it is necessary to remove the water from the silt, the silt is thrown into the silt storage space formed by the slag cage wall 1, the lifting seat 5 and the slag cage wall column (3) by a loader. At this time, the water in the silt passes through the filter layer 7 under the action of gravity and flows out from the air holes of the inner wall of the slag cage wall 1, the outer wall of the slag cage wall column (3) and the lifting seat 5, respectively into the inner wastewater pool 2 and the outer wastewater pool 4. After a period of stillness, when there is no obvious discharge in the silt, the lifting seat 5 is driven to move upward off the ground by the lifting seat control system 8. The clump of silt rises with the lifting seat 5. When the clump of silt partially emerges from the top of the slag cage wall 1, the lifting seat 5 is stopped from rising and the excavator is allowed to dig out the part of the silt that has emerged. The lifting seat 5 rises a little and the excavator digs out the emerging silt until the silt is completely cleared.

[0041] Before the second cleaning, the filter layer 7 laid on the rubble cage wall 1, the lifting seat 5 and the rubble cage wall column (3) needs to be removed, and the lifting seat 5 is lifted out. The filter layer 7 and the lifting seat 5 are cleaned with a high-pressure water gun to remove the remaining silt. After cleaning, the filter layer 7 is laid on the inner and outer walls of the rubble cage wall 1 and the rubble cage wall column (3). Then the lifting seat is lowered, and finally a layer of filter layer 7 is laid on the upper surface of the lifting seat 5. Then the next batch of silt drainage operation can be carried out.

[0042] Please refer to this carefully. Figures 1-5 An isolation layer 71 is laid on the bottom of the inner wastewater pool 2, the bottom of the outer wastewater pool 4, and the ground between the inner wastewater pool 2 and the outer wastewater pool 4. The isolation layer 71 is an impermeable geomembrane.

[0043] In this embodiment: the isolation layer 71 can effectively prevent pollution from seeping into the ground and will not cause pollution damage to the ground in the work area. When the sewage in the external wastewater pool 4 is full, it is pumped out and treated from the outside. This has been described in the prior art and will not be elaborated here.

[0044] Please refer to this carefully. Figures 1-5The upper end of the inner wastewater tank 2 is connected to an air extraction pipe 21, which is connected to an external air pump to extract air from the inner wastewater tank 2, thereby creating a negative pressure in the inner wastewater tank 2. The lower end of the inner wastewater tank 2 is connected to a first water extraction pipe 22, one end of which is connected to an external water pump. An electrically controlled valve 23 is installed on the first water extraction pipe 22 to cooperate with the external pump to control the first water extraction pipe 22 to extract the wastewater accumulated in the inner wastewater tank 2.

[0045] The outer end of the external wastewater pool 4 is connected to a second pumping pipe 41, which is connected to an external pumping pump to pump out the wastewater accumulated in the external wastewater pool 4. An air pump 9 is installed on the top of the cover plate 61. The input end of the air pump 9 is matched and connected to the air extraction hole 611 in the middle of the cover plate 61 to draw air from the cylinder 6 so as to create a negative pressure inside the cylinder 6. A sealing layer 72 is provided on the upper outer wall of the crushed stone frame wall column 3. The lower end of the sealing layer 72 is lower than the top of the crushed stone frame wall 1. The sealing layer 72 is a sealing membrane.

[0046] In this embodiment: Under the sealing effect of the cover plate 61, the bottom plate 62 and the sealing layer 72, the inner cavity of the cylinder 6 is only connected to the inner wastewater pool 2. By using the air pump 9 to remove the air from the inner wastewater pool 2 and the cylinder 6, a near-vacuum environment can be achieved inside both the inner wastewater pool 2 and the cylinder 6. This accelerates the flow of liquid moisture in the silt in the crushed stone cage wall 1, promotes the simultaneous multi-directional drainage of the silt inside the crushed stone cage wall 1 to the bottom, and improves the drainage rate.

[0047] It should be noted that when air needs to be drawn from the inner wastewater tank 2, the electric valve 23 is in the closed state. When the inner wastewater tank 2 needs to be discharged, the electric valve is in the open state, and the sewage in the inner wastewater tank 2 is drawn out by the external water pump through the first water suction pipe, thus completing the discharge of sewage from the inner wastewater tank 2.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
