Description

Technical Field

[0001] The present application relates to the technical field of geotechnical engineering, and in particular to a method for filling reinforcement bags with fluidized solidified soil and stacking retaining walls using the reinforcement bags. Background Art

[0002] During the construction process, when a slope needs to be transformed into a flat site, retaining walls can be used to support the soil and form flat terraces of different heights to meet the flatness requirements of the project construction.

[0003] Among existing retaining wall construction technologies, commonly used methods include reinforced concrete retaining walls and traditional earthbag retaining walls. However, these traditional methods present certain problems, particularly in terms of environmental protection. While reinforced concrete retaining walls are structurally strong, their production and transportation produce large amounts of wastewater and dust, which adversely impact the environment. While traditional earthbag retaining walls can reduce environmental pollution, they have poor seismic resistance and durability, resulting in a short service life. In particular, when the bags age or become damaged, the sand and soil within them can easily escape, threatening the stability of the retaining wall.

[0004] In order to solve the above problems, fluidized solidified soil has been used to make retaining walls. Fluidized solidified soil is a new type of material made from engineering waste slurry, construction debris, river sludge, original soil, etc., mixed with an appropriate amount of curing agent and water that is compatible with the rock and soil characteristics. It is more environmentally friendly to use.

[0005] However, during the production process of the fluidized solidified soil retaining wall, it is necessary to support it by building a formwork and fill it before it can be completed, which results in low construction efficiency; and the larger volume of the fluidized solidified soil retaining wall is prone to cracking due to water segregation during the solidification process, resulting in insufficient strength of the retaining wall structure. Summary of the Invention

[0006] In order to improve construction efficiency and ensure the structural strength of retaining walls, the present application provides a method of filling reinforcement bags with fluidized solidified soil and stacking retaining walls using the reinforcement bags.

[0007] The present application provides a method for filling reinforcement bags with fluidized solidified soil and stacking retaining walls using the reinforcement bags, which adopts the following technical solutions: A reinforcement bag for filling fluidized solidified soil comprises a bag body for filling fluidized solidified soil, the bag body comprising bag walls and reinforcement bars for fixing the shape of the bag body, the reinforcement bars being connected at the junctions between adjacent bag walls, and a filling bag opening for pouring fluidized solidified soil being provided at the top of the bag body.

[0008] By adopting the above technical solution, the fluidized solidified soil is filled into the bag body, and after solidification, it forms blocks, which are convenient for subsequent stacking and other operations; the tie bars on each side of the bag body can shape the bag body, preventing the bag body from expanding during the filling process and causing the shape of the blocks to change; in addition, the bag body blocks external air drying, and the high moisture content of the fluidized solidified soil inside forms a closed internal environment, delaying water evaporation; the curing reaction requires continuous water participation, and the bagged structure allows the water to be recycled internally, improving hydration efficiency.

[0009] Optionally, a suture line is provided around the opening of the filling bag, and the suture line is flush with the top surface of the bag body.

[0010] By adopting the above technical solution, it can be effectively ensured that the top of the bag is flat after suturing, so that the fluidized solidified soil can form flat blocks inside the bag, thereby facilitating subsequent stacking and other operations and improving ease of use.

[0011] Optionally, the pouring bag is provided with two openings and are respectively arranged at both ends of the bag body. The filling height of the fluidized solidified soil in the pouring bag opening is 1 / 4-1 / 2 of the height of the pouring bag opening. The fluidized solidified soil in the pouring bag opening forms a convex column after solidification, and the bottom of the bag body is provided with a groove that cooperates with the convex column.

[0012] By adopting the above technical solution, a pouring bag opening is set at each end to ensure that the fluidized solidified soil can be evenly injected from both ends. While improving the filling speed of the fluidized solidified soil, the uniformity of the solidified soil inside the bag is guaranteed, thereby enhancing the overall structural strength; the convex column and the groove cooperate to achieve a positioning effect. When the reinforcement bags are stacked, the convex column of one reinforcement bag cooperates with a groove at the bottom of the other two reinforcement bags, thereby effectively ensuring staggered stacking. The vertical load is transferred through the staggered transmission between the blocks, avoiding stress concentration on a single vertical joint and reducing the risk of local compressive damage.

[0013] Optionally, a fixed clamp is sleeved on the outer periphery of the perfusion bag mouth, and the fixed clamp includes a top ring sleeved on the opening of the perfusion bag mouth, a bottom ring sleeved on one end of the perfusion bag mouth close to the bag wall, and a support column fixedly connected to the bottom of the top ring, the top of the bottom ring is connected to a sleeve sleeved on the support column, a sliding block is fixedly connected to one side of the support column, and the inner wall of the sleeve is provided with a telescopic groove and a locking groove for the movement of the sliding block, the telescopic groove is vertically arranged, and the locking groove is horizontally arranged and connected to the telescopic groove.

[0014] By adopting the above technical solution, the fixed clamp can realize telescopic operation, and the top ring is pulled and rotated so that the fixed clamp reaches the maximum length and is fixed. At this time, the filling bag mouth can be stably fixed, so that during the filling process, the bag mouth is not easily retracted due to the excessive filling speed, resulting in abnormal filling process; when the fixed clamp is contracted, the filling bag mouth can be effectively closed and the height of the filler in the filling bag mouth can be limited, thereby effectively ensuring the height consistency of the convex column during forming.

[0015] Optionally, a filling piece is provided inside the groove, and the filling piece includes a cylinder and a fixing ring connected to one end of the cylinder. A shaping cavity is provided on the side of the cylinder close to the fixing ring. The outer wall of the cylinder fits with the inner wall of the groove, and the inner diameter of the shaping cavity is equal to the outer diameter of the top ring.

[0016] By adopting the above technical solution, during the process of pouring fluidized solidified soil into the bag body, the filling piece is inserted into the groove, and the outer wall of the cylinder fits with the inner wall of the groove, thereby playing an effective structural support role and preventing the groove from collapsing; after the filling is completed, the filling piece can play a stable supporting and shaping role while waiting for solidification, so that the shape of the groove is consistent.

[0017] At the same time, compared with the fluidized solidified soil at the bag mouth, the fluidized solidified soil at the bottom of the bag has more moisture and better humidity conditions, and its solidification speed is faster. After the fluidized solidified soil at the bottom solidifies to form a groove, the filler is taken out and fitted with the fixing clamp. The shaping cavity of the filler can cooperate with the fixing clamp to help the convex column to shape and retract the bag mouth, thereby reducing water evaporation and improving curing efficiency.

[0018] Optionally, a reinforcement frame is connected to the inner wall of the molding cavity, and the reinforcement frame includes a beam fixedly connected to the top wall of the molding cavity and supporting legs fixedly connected to the bottom of both ends of the beam.

[0019] By adopting the above technical solution, the structural strength of the cylinder is effectively enhanced, preventing the cylinder from being deformed due to the extrusion of the fluidized solidified soil, which may cause the filling piece to be unable to play an effective shaping role, and ensuring stability during the molding process.

[0020] Optionally, a placement groove for placing the crossbeam is provided on the top of the top ring, and plug-in grooves for inserting the legs are provided on the side walls of the top ring and the bottom ring.

[0021] By adopting the above technical solution, the filling piece can be plugged into the fixed clamping ring, and the reinforcing ribs on the inner wall of the filling piece can cooperate with the placement groove and the plug-in groove of the top ring, so that the reinforcing ribs can not only improve the structural strength of the accommodating cavity, but also be plugged into the top ring and the bottom ring, so that the filling piece can drive the top ring to rotate, thereby realizing the unlocking of the fixed clamping ring and facilitating the operation of closing the filling bag mouth.

[0022] A method for stacking retaining walls using reinforcement bags comprises the following steps: S1: Filling the fluidized solidified soil into the reinforcement bag; S2: After solidification, the opening of the perfusion bag is mechanically sutured or closed; S3: Stack the fluidized solidified soil reinforcement bags in staggered positions to form a retaining wall, with the daily stacking height not exceeding 1.5m; S4: 3 days after the retaining wall is stacked, a vegetation blanket is laid on the free-facing side of the retaining wall; S5: 7 days after the retaining wall is stacked, concrete is poured on the top surface of the retaining wall.

[0023] By adopting this technical solution, the vertical and lateral pressure generated by the deadweight during the stacking process significantly improves the density and stability of the retaining wall structure, enhancing its structural strength. A vegetation blanket is laid on the free-facing side of the retaining wall, and the top surface is covered with concrete to protect it from sunlight. This helps delay the aging of the reinforcement bags and reduces the weathering of the fluidized solidified soil, effectively extending the service life of the retaining wall.

[0024] Optionally, one side of the vegetation blanket is covered with an adhesive to form an adhesive layer.

[0025] By adopting the above technical solution, the adhesive construction method is more convenient. The adhesive is directly applied and the vegetation mat is pasted, which shortens the construction period and enables the rapid installation of the vegetation mat. In addition, the position of the vegetation mat can be adjusted at any time during the construction process to ensure smooth laying and reduce the probability of rework.

[0026] Optionally, fixing nails are provided on the edge of the vegetation blanket.

[0027] By adopting the above technical solution, the fixing nails can effectively anchor the vegetation blanket to prevent the blanket from sliding or curling due to wind, water flow or gravity; and by reasonably arranging the fixing nails, the vegetation blanket can fit closely with the base layer, dispersing the impact of external forces on the local area and improving the overall anti-scouring ability.

[0028] In summary, this application has the following beneficial effects: 1. Pour the fluidized solidified soil into the reinforcement bags and stack them to form a retaining wall, so as to divide the large volume of solidified soil into small bagged units, effectively disperse the temperature stress and drying shrinkage stress, and avoid through cracks in the retaining wall.

[0029] 2. By setting a fixed clamp ring, the bag opening is not easily retracted due to excessively fast pouring speed during the pouring of fluidized solidified soil, effectively ensuring the stability of the pouring process; when the fixed clamp ring shrinks, the bag opening can be effectively closed, the height of the bag opening can be limited, and the length of the convex column can be controlled.

[0030] 3. By setting up filling pieces and reinforcement frames, the grooves are effectively supported to prevent the grooves from collapsing during the curing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-10 This application is described in further detail.

[0033] The embodiments of the present application disclose a method for filling a reinforcement bag with fluidized solidified soil and stacking a retaining wall using the reinforcement bag.

[0034] Example 1: Reference Figure 1 、 Figure 2The fluidized solidified soil filling and reinforcement bag includes a bag body 1 for filling the fluidized solidified soil. The bag body 1 includes a bag wall 11 and reinforcement bars 12 for fixing the shape of the bag body 1. The reinforcement bars 12 are fixedly connected to the junction between adjacent bag walls 11. The reinforcement bars 12 are connected end to end to form a rectangular parallelepiped frame. A pouring bag opening 2 for pouring the fluidized solidified soil is provided on the top of the bag body 1. The rectangular parallelepiped frame formed by the reinforcement bars 12 plays a shaping role, so that the fluidized solidified soil can be effectively shaped into a rectangular block after being filled into the bag body 1, preventing the shape of the block from changing due to the expansion of the bag body 1 during the filling process; and after the filling is completed, a closed space is formed inside the bag body 1, which effectively blocks external air drying and effectively reduces water evaporation, so that the fluidized solidified soil inside the bag body 1 can be fully solidified, thereby improving the hydration efficiency.

[0035] Reference Figure 1 、 Figure 2 The pouring bag opening 2 is cylindrical and has sutures 21 circumferentially disposed thereon, flush with the top wall of the bag body 1. Suturing the bag opening 2 with the sutures 21 and trimming off excess filler 2 ensures that the fluidized solidified soil within the bag body 1 forms a closed space, facilitating the solidification reaction of the fluidized solidified soil within the bag body 1. The flushing of the sutures 21 with the top wall of the bag body 1 ensures that the fluidized solidified soil forms a flat block, facilitating subsequent stacking and other operations, and improving ease of use.

[0036] Reference Figure 3 The method of stacking the retaining wall 6 using the reinforcement bag comprises the following steps: S1: The fluidized solidified soil is poured into the bag from the pouring bag port 2 inside the bag 1, the reinforcement bar 12 can effectively ensure the overall shape of the bag 1; S2: After filling is completed, the perfusion bag 2 is sewn along the suture line 21 so that the top of the bag 1 is flat; S3: Stacking the reinforcement bags in staggered manner to form a retaining wall 6; S4: After the stacking is completed, the vegetation blanket 3 is pasted on the free surface of the retaining wall 6 and fixing nails are inserted along the edge of the vegetation blanket 3; S5: After stacking is completed, concrete is poured on the top of the retaining wall 6 to form a concrete layer 61.

[0037] The step S51 may be followed by step S51: coating and curing the concrete. In this way, the evaporation of water is physically isolated, thereby maintaining a continuous and uniform wet environment and effectively improving the strength, crack resistance and durability of the concrete layer 61.

[0038] Reference Figure 3The fixing nails 31 passed through the edge of the vegetation blanket 3 can ensure that the vegetation blanket 3 is stably fixed on one side of the retaining wall 6 to avoid bottoming out, sliding or curling due to wind, water flow or gravity; and the vegetation blanket 3 can form a "reinforcement effect" with the plant roots on its surface, thereby enhancing the slope's ability to resist scour.

[0039] Example 2: The difference from Example 1 is that there are two filling bag openings 2 and a groove 13 is provided at the bottom of the bag body 1.

[0040] Reference Figure 4 、 Figure 5 The two pouring bag openings 2 are respectively provided at both ends of the top wall of the bag body 1. The filling height of the fluidized solidified soil in the pouring bag openings 2 is 1 / 4-1 / 2 of the height of the pouring bag openings 2. After the fluidized solidified soil in the pouring bag openings 2 solidifies, protrusions 22 for inserting into the grooves 13 are formed. The number of grooves 13 is consistent with the number of protrusions 22. By providing two pouring bag openings 2, the pouring speed of the fluidized solidified soil can be effectively improved, and pouring the fluidized solidified soil from the two sides of the pouring bag openings 2 at the same time can ensure the uniformity of the fluidized solidified soil inside the bag body 1, so that the overall structural strength can be effectively guaranteed after solidification. The protrusions 22 cooperate with the grooves 13 to achieve an effective positioning effect. When stacking, the two protrusions 22 on the top of a single reinforcement bag can respectively cooperate with a groove 13 at the bottom of the other two reinforcement bags, thereby ensuring staggered stacking during stacking, so that the vertical load can be staggered and transferred, avoiding stress concentration and reducing the risk of wall collapse caused by local pressure.

[0041] Reference Figure 5 、 Figure 6 and Figure 7 A fixed snap ring 5 is sleeved on the outer periphery of the perfusion bag mouth 2. The fixed snap ring 5 includes a top ring 51 fixedly connected to the opening of the perfusion bag mouth 2, a bottom ring 52 fixedly connected to the end of the perfusion bag mouth 2 close to the bag wall 11, and a support column 53 fixedly connected to the bottom of the top ring 51. A sleeve 54 is fixedly connected to the top of the bottom ring 52 and sleeved on the support column 53. The inner cavity of the sleeve 54 is L-shaped and is used for the support column 53 to slide. A sliding block 531 is fixedly connected to the side wall of the support column 53. The inner wall of the sleeve 54 is provided with a telescopic groove 541 and a locking groove 542 for the sliding block 531 to move. The telescopic groove 541 is vertically arranged, and the locking groove 542 is horizontally arranged and connected to the telescopic groove 541 near the end of the top ring 51.

[0042] The expansion and contraction of the fixed clasp 5 is achieved through the expansion slot 541 and the sliding block 531. When the fixed clasp 5 is stretched to its maximum length, the sliding block 531 can be locked by rotating the top ring 51 so that it enters the locking slot 542. At this time, the fixed clasp 5 is fixed at its maximum length. At this time, the bottom of the support column 53 abuts the inner wall of the sleeve 54 to provide effective support. During the pouring process, the bag mouth can always remain vertical and is not easily retracted due to excessive pouring speed, which may cause pouring anomalies, thus ensuring the stability of the pouring process. After pouring is completed, the top ring 51 can be rotated in the opposite direction to unlock it. At this time, the top ring 51 presses down, causing the bag mouth to close and limiting the height of the fluidized solidified soil in the pouring bag mouth 2, thereby ensuring the height of the protrusion 22 formed by subsequent solidification is consistent, ensuring the consistency of the building block.

[0043] In this embodiment, a single locking groove 542 is provided, located at the end of the telescopic groove 541 near the top ring 51. In other embodiments, the number of locking grooves 542 can be increased to achieve different telescopic length adjustments. In contrast, in this embodiment, a single locking groove 542 is sufficient to both lock the post 22 and maintain its length.

[0044] Reference Figure 5 、 Figure 8 The grooves 13 at the bottom of the bag body 1 are all plugged with fillers 4. The fillers 4 include a cylinder 41 and a fixing ring 42 circumferentially connected to one end of the outer wall of the cylinder 41. A shaping cavity 411 is opened inside the cylinder 41. The opening of the shaping cavity 411 is close to one side of the fixing ring 42. The outer wall of the cylinder 41 fits the inner wall of the groove 13. The inner diameter of the shaping cavity 411 is equal to the outer diameter of the top ring 51. The filling piece 4 is inserted into the groove 13 so that the overall shape of the groove 13 is effectively supported, thereby ensuring that the groove 13 is not prone to collapse during the filling process of the fluidized solidified soil, ensuring the accurate shaping of the groove 13; and, since the inner diameter of the shaping cavity 411 is equal to the outer diameter of the top ring 51, the filling piece 4 can be taken out of the groove 13, and the filling piece 4 is sleeved on the outer periphery of the fixed clamping ring 5, the pouring bag mouth 2 is folded and the fixed clamping ring 5 and the pouring bag mouth 2 are received in the shaping cavity 411, further delaying the evaporation of water and improving the hydration efficiency of the fluidized solidified soil in the bag body 1.

[0045] Reference Figure 8 A reinforcement frame 43 is fixedly connected to the inner wall of the shaping cavity 411. The reinforcement frame 43 includes a crossbeam 431 fixedly connected to the inner top wall of the shaping cavity 411 and legs 432 fixedly connected to both ends of the crossbeam 431. The sidewalls of the legs 432 are fixedly connected to the inner wall of the shaping cavity 411. The reinforcement frame 43 further enhances the structural strength of the cylinder 41, preventing deformation of the cylinder 41 due to compression by the fluidized solidified soil during the filling process, which would prevent the filler 4 from effectively shaping the groove 13, thereby ensuring the stability of the groove 13 during the forming process.

[0046] Reference Figure 6 , Figure 8 and Figure 9 The top of the top ring 51 is provided with a placement groove 511 for inserting the crossbeam 431, and the outer walls of the top ring 51 and the bottom ring 52 are both provided with insertion grooves 55 for inserting the legs 432. When the filler 4 is sleeved on the fixed clamping ring 5, the reinforcing ribs in the fixed cavity 411 can cooperate with the placement groove 511 and the insertion groove 55 of the top ring 51. While the reinforcing ribs play a role in improving the structural strength of the accommodating cavity, they can also be inserted into the top ring 51 and the bottom ring 52, thereby facilitating the filling piece 4 to drive the top ring 51 to rotate, thereby achieving the locking and unlocking of the fixed clamping ring 5, and facilitating the operation of closing the filling bag opening 2.

[0047] Reference Figure 10 The method of stacking retaining walls using reinforcement bags includes the following steps: S1: Stretch and fix the clamp ring 5 to keep the grouting bag opening 2 vertical and fill the reinforcement bag with fluidized solidified soil; S2: Take the filling piece 4 out of the groove 13 and put it on the fixed clamping ring 5, rotate the filling piece 4 and press down the top ring 51 to close the filling bag opening 2; S3: Insert the two protrusions 22 on the top of one lacing bag into the grooves 13 on the bottom of the other two lacing bags to achieve staggered stacking; S4: 3 days after the retaining wall 6 is stacked, a vegetation blanket 3 is attached to the free surface of the retaining wall 6 and fixing nails 31 are installed along the edge of the vegetation blanket 3; S5: 7 days after the retaining wall 6 is stacked, concrete is poured on the top surface of the retaining wall 6 to form a concrete layer 61.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
