Description

Technical Field

[0001] The invention belongs to the technical field of storage silo structures, and in particular relates to a storage silo structure with multiple internal compartments and a construction method thereof. Background Art

[0002] Reinforced concrete silos are a common structure for storing materials. Due to their structural characteristics, they are widely used in storage work in many industries.

[0003] At present, due to the diversity of material varieties, it is often necessary to build multiple independent silos to store different materials. Multiple independent silos often occupy a large area, have a long construction period, and use a large amount of concrete, which increases the project cost;

[0004] With the development of social economy, the classification of various materials is becoming more and more refined, and the categories are increasing. How to further improve the storage utilization rate and achieve efficient storage based on the existing technology is also a topic that needs to be studied urgently.

[0005] At present, silo structures often use a combination of pressure relief cones and partition walls to improve storage utilization. However, due to the irregular shapes and sizes of the pressure relief cones and partition walls, they cannot be directly constructed in an integral sliding form with the silo wall of the warehouse, resulting in the construction progress being slowed down by stages and steps. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the prior art and provide a storage silo structure with multiple internal partitions and a construction method thereof. The conical structure of the pressure reducing cone is used as the boundary, and two different structures and construction methods are adopted to connect the partition wall and the silo wall of the warehouse body, so as to ensure the stability of the special-shaped pressure reducing cone and the partition wall. On the conventional slipform system, the silo wall and the partition wall are constructed by an assisted construction method of close cooperation between slipform construction and flip mold construction. Then, the remaining part of the silo of the remaining warehouse is completed by the overall sliding mold process by connecting the silo wall and the partition wall lifting platform as a whole, thereby ensuring the overall stability of the slipform platform and greatly accelerating the construction progress.

[0007] The object of the present invention is achieved through the following technical solutions:

[0008] A storage silo structure with multiple inner compartments, comprising a silo and a decompression cone arranged in the silo, wherein the decompression cone is a conical structure, a supporting cylinder wall extends upward from a base portion at the bottom of the silo, the decompression cone has a ring beam in contact with the supporting cylinder wall, and the decompression cone is also connected to a plurality of partition walls surrounding the decompression cone along its circumference, and the partition walls are connected to the inner wall of the silo;

[0009] The portion of the partition wall between the ring beam and the pressure reducing cone is subjected to overmolding construction, the inner wall of the silo between the ring beam and the pressure reducing cone is subjected to slip-form construction, the partition wall in this portion is connected to the inner wall of the silo by a mortise and tenon structure, and the portion of the partition wall exceeding the height of the overmolding construction is subjected to integral slip-form construction together with the inner wall of the silo.

[0010] In one embodiment, the mortise and tenon structure includes a recessed groove opened on the inner wall of the silo and a protrusion provided at one end of the partition wall close to the inner wall of the silo, and the protrusion and the recessed groove are engaged with each other;

[0011] Through this implementation, the torsion between the concrete partition wall and the silo wall can be effectively limited, making the connection between the partition wall and the silo more secure. At the same time, it can withstand larger horizontal and vertical loads, allowing a certain slight horizontal deformation, reducing the impact of uneven horizontal load stress, and there is no need to add other connecting components such as anchor bolts, so that the structure forms an integral whole and has a unified appearance.

[0012] The present invention also provides a construction method of a multi-channel internal compartment, comprising the following steps:

[0013] Step S1, firstly perform sliding construction on the supporting wall part of the silo;

[0014] Step S2, first complete the partial slipform construction of the silo wall that exceeds the ring beam elevation, and then use the flip mold method to construct the pressure relief cone and multiple partition walls between the silo wall and the pressure relief cone;

[0015] Step S3, then complete the integral sliding formwork concrete pouring of the partition wall and the silo and lift them up at the same time at a height exceeding the height corresponding to the top elevation of the decompression cone to the top of the silo.

[0016] In one embodiment, in step S1, construction is performed from the top of the foundation to the bottom of the ring beam of the pressure relief cone from bottom to top, and according to the designed thickness of the supporting cylinder wall part, a layer is poured every 30 cm until the height of the bottom of the ring beam is reached.

[0017] In one embodiment, in step S2, it includes:

[0018] After the construction reaches the height of the bottom of the ring beam, the slipform construction is suspended, the mold is changed to the preset silo wall thickness, and then the slipform construction is carried out on the inner wall of the silo. The construction range of the slipform is the section between the top elevation of the ring beam and the top of the conical structure.

[0019] Then, the pressure relief cone and the partition wall inside the warehouse are re-moulded within the construction scope of this section;

[0020] In one embodiment, in step S2, the mold-turning construction of the pressure relief cone and the partition wall also includes:

[0021] First construct the ring beam of the pressure relief cone and the root of the partition wall;

[0022] The mold-turning construction method is then used to divide the multi-layer construction range from bottom to top for segmented flow construction. During the mold-turning construction process, the scaffolding and formwork are constructed simultaneously to exceed the height corresponding to the conical structure.

[0023] In one embodiment, in step S3, it also includes:

[0024] First, remove the formwork of the partition wall in the decompression cone, use the decompression cone and the partition wall to construct the support scaffolding platform, and reassemble and set up the slipform operation platform so that it is reinforced and connected in parallel with the cabin wall at the construction height corresponding to the cone structure to form an overall lifting platform system, so that the cabin and the partition wall can be lifted to the warehouse top elevation by slipform at the same time.

[0025] In one embodiment, in step S2, in the process of dividing the multi-layer construction range from bottom to top for segmented flow construction, it also includes:

[0026] During the slipform assembly process, the silo wall and the lock beam structure on the inner side of the silo wall are constructed first to allow the partition wall and the silo wall to be tightly connected by mortise and tenon joints.

[0027] The beneficial effects of the present invention are:

[0028] The silo structure and construction method provided by the present invention adopt a combination of sliding formwork and flipping formwork to solve the problem of slow construction caused by the continuous change of the cross-section of the silo structure and the presence of special-shaped irregular components such as partition walls, inverted cones and ring beams. That is, in the construction range between the ring beam and the cone structure, the pressure relief cone and the partition wall are flipped for construction, and a mortise and tenon structure is designed for connection between the two to ensure the safety and quality of the silo. Above the height range matching the cone structure, the silo wall and the partition wall are connected into a whole and constructed together using sliding formwork. This can save at least 30% of materials and labor and reduce one third of the construction period during the construction of the silo with the pressure relief cone and the partition cabin, while ensuring the safety of the structure, adapting to a small construction site and reducing construction noise.

[0039] The present invention will be further described below in conjunction with the accompanying drawings.

[0040] The present invention provides a storage silo structure with multiple internal compartments, such as Figures 1 to 3 As shown, the decompression cone 2 includes a silo 8 and a decompression cone 2 disposed in the silo 8. The decompression cone 2 is a conical structure. A supporting cylinder wall 5 extends upward from the base portion at the bottom of the silo 8. The decompression cone 2 has a ring beam 4 in contact with the supporting cylinder wall 5. The decompression cone 2 is also connected to a plurality of partition walls 3 surrounding the decompression cone 2 along its axial direction. The partition walls 3 are connected to the inner wall of the silo 8.

[0041] Specifically, Figure 3 As shown, the pressure reducing cone 2 is connected to three partition walls 3 , and the three partition walls intersect each other at a height exceeding the pressure reducing cone 2 to form a partition wall intersection 1 .

[0042] The portion of the partition wall 3 between the ring beam 4 and the pressure relief cone 2 is subjected to the over-molding construction, and the inner wall of the silo 8 between the ring beam 4 and the pressure relief cone 2 is subjected to the slip-molding construction. The partition wall 3 of this portion is connected to the inner wall of the silo 8 through a mortise and tenon structure, and the portion of the partition wall 3 exceeding the height of the over-molding construction is subjected to the integral slip-molding construction with the inner wall of the silo 8;

[0043] It should be noted that if Figures 1 to 3As shown, in this embodiment, the inner diameter of the silo 8 is 22.5m, the thickness of the supporting wall 5 is 800mm, the thickness of the silo wall above the supporting wall 5 is 400mm, the total height of the silo 8 is 62.5m, and it is divided into three independent compartments by the partition wall 3, as shown in FIG. Figure 3 As shown, within the range between the elevation of 13m and the elevation of 30.658m, due to the irregular components such as the pressure relief cone 2, the partition wall 3 and the ring beam 4, the partition wall 3 is separated from the inner wall of the silo 8, and the flip mold construction and the slip mold construction are respectively carried out, that is, the slip mold construction of the silo 8 is carried out first, and then the pressure relief cone 2 and the partition wall 3 are made, that is, the flip mold construction method is adopted, as shown in FIG. Figure 4 and Figure 6 As shown, the partition wall 3 is connected to the warehouse wall by a mortise and tenon structure to ensure the stability and safety of the inner partition wall under separate construction. In the range between the elevation of 30.658m and the elevation of 62.5m, as shown in FIG. Figure 5 As shown, the partition wall 3 and the inner wall of the silo 8 are in the form of an integral sliding form, which can ensure the safety of the silo 8 and greatly improve the construction progress;

[0044] In one embodiment, the mortise and tenon structure includes a recessed groove 6 opened on the inner wall of the silo 8 and a protrusion 7 provided at one end of the inner wall of the partition wall 3 close to the silo 8, and the protrusion 7 and the recessed groove 6 are engaged with each other. The partition wall 3 and the silo 8 are connected by the mortise and tenon structure in which the protrusion 7 and the recessed groove 6 are engaged with each other, which can effectively limit the twisting between the concrete partition wall 3 and the silo wall of the silo 8, making the connection between the partition wall 3 and the silo 8 more secure, and can also withstand larger horizontal and vertical loads, allowing a certain slight horizontal deformation, reducing the impact of uneven stress of horizontal loads, and no other connecting components similar to anchor bolts need to be added, so that the structure is integrated and has a unified appearance;

[0045] The present invention also provides a construction method of a multi-channel internal compartment, comprising the following steps:

[0046] Step S1, firstly, the supporting wall of the silo is constructed by sliding, and the construction is carried out from the top of the foundation to the bottom of the ring beam of the pressure relief cone from bottom to top. According to the designed thickness of the supporting wall, one layer is poured every 30 cm until the height of the bottom of the ring beam is reached;

[0047] Step S2, first complete the partial slipform construction of the silo wall that exceeds the ring beam elevation, and then use the flip mold method to construct the pressure relief cone and multiple partition walls between the silo wall and the pressure relief cone, including:

[0048] Step S201, after the construction reaches the height of the bottom of the ring beam, the slipform construction is suspended, the mold is changed to the preset silo wall thickness, and then the slipform construction is performed on the inner wall of the silo, and the construction range of the slipform is the partial section between the top elevation of the ring beam and the top of the conical structure;

[0049] Step S202, performing mold turning construction of the pressure relief cone and the partition wall in the warehouse within the construction range;

[0050] Step S2021, first construct the ring beam of the pressure relief cone and the root of the partition wall;

[0051] Step S2022: Use the mold turning construction method to divide the multi-layer construction range from bottom to top for segmented flow construction, and during the mold turning construction process, the scaffolding and the template are synchronously constructed to exceed the height corresponding to the conical structure;

[0052] Among them, the process of dividing the multi-layer construction scope from bottom to top for segmented flow construction also includes:

[0053] During the slipform assembly process, the silo wall and the locking beam structure inside the silo wall are constructed first, so that the partition wall and the silo wall can be tightly connected by mortise and tenon joints;

[0054] Step S3, then completing the integral sliding formwork concrete pouring and simultaneous lifting of the partition wall and the silo to the top of the silo at the construction height corresponding to the conical structure, including:

[0055] First, remove the formwork of the partition wall in the decompression cone, use the decompression cone and the partition wall to construct the support scaffolding platform, and reassemble and set up the slipform operation platform, so that it can be reinforced and connected in parallel with the cabin wall at the construction height corresponding to the cone structure to form an integral lifting platform system, so that the cabin and the partition wall can be lifted to the warehouse top elevation by slipform at the same time;

[0056] It should be noted that the construction method provided in this embodiment is applicable to a silo structure using a special-shaped pressure relief cone, such as Figure 3 As shown, it is used as an illustration of this embodiment.

[0057] First, formwork is assembled from the top of the foundation -3.10m to the elevation +13.0m to support the cylinder wall sliding;

[0058] +13.00m~+30.57m silo concrete wall sliding (sliding formwork will be suspended after completion);

[0059] +13.00m~+30.57m pressure relief cone and compartment shear wall construction;

[0060] Integral slipform concrete pouring and simultaneous lifting of +35.70~+62.50m silo and three inner partition walls;

[0061] That is, the silo wall and the partition wall have a good sliding form and a turning form that cooperate closely to assist in the construction, and then the overall assembly connects the silo wall and the partition wall lifting platform into one, ensuring the overall stability of the sliding form platform during the sliding form construction of the upper structure. In this way, the structure is safe and stable, the construction time is fast and saved, the use of turnover materials is reduced, the construction progress is accelerated, the construction period is shortened, and safety risks are avoided;

[0062] In this embodiment, the main project only takes 45 days, the construction period is shortened by 75 days, the formwork materials required are 1400 square meters, and the formwork materials can be saved by 4800m 2 In the traditional construction method, the construction period of the silo wall and the main compartment construction alone is at least 120 days, and the formwork material of the silo body alone requires 5,600m 2 , saving about 130,000 yuan in labor costs, about 260,000 yuan in material costs, and a total of about 390,000 yuan in costs. Each silo can reduce the input of scaffolding steel pipes by about 300 tons. The use of prestressed reinforced concrete construction technology reduces the thickness of the silo wall concrete, the amount of steel bars and concrete, and reduces the project cost, achieving significant progress;

[0063] Specifically, Figures 1 to 6 As shown, in step S1:

[0064] As the first stage of the entire construction, that is, the construction part of the supporting cylinder wall, from the top of the foundation -3.10m to the bottom of the ring beam of the pressure relief cone of +13.0m, the cylinder wall thickness is 800mm. During the slipform construction, the concrete formwork height is poured every 30cm on average. A truck pump is used to transport concrete into the formwork, and the tower crane is responsible for the lifting and transportation of steel bars and construction materials;

[0065] Before assembling the lifting platform, first find the center on the lifting starting surface, set up a total station at the center, use the total station to find the correct position of the lifting frame according to the calculated angle and pop it out with an ink line (or use a steel ruler to measure the position of the lifting frame according to the calculated chord length), try to avoid arranging the lifting door frame at the opening and large-sized embedded parts, tie the warehouse wall ring reinforcement to a height of 1.3m before assembly, and do a good job of safety technical explanation;

[0066] Further, in step S2:

[0067] As the second phase of the entire construction,

[0068] First, change the mold, stop the slipform at +13.0m, change the thickness of the silo wall from 800mm to 400mm, then complete the slipform construction from the warehouse ring beam bottom elevation +13.0m to the pressure relief cone elevation +30.568m, then stop the slipform construction, and use the silo slipform process. At the same time, in order to ensure that the partition wall of the subsequent construction is well bitten with the cement silo wall, during the slipform assembly, such as Figure 6 As shown, firstly, the buttress columns and locking beam structures 9 of the mortise and tenon structures on both sides are constructed according to the design drawings, and three partition walls are provided with 6 mortise and tenon structures. The locking beam structure protrudes from the inner side of the warehouse wall, and the distribution position is the same as the design layout of the prestressed wall guard column;

[0069] Then, the pressure relief cone structure and three partition walls are constructed by re-moulding from bottom to top:

[0070] According to the design and construction plan parameters, the pressure relief cone full-floor scaffolding and bottom formwork were set up, and the pressure relief cone and partition wall were divided into 3 layers and 4 sections from the bottom to the top at an elevation of +16.79m. The construction height of each layered mold turning was about 4.8m, until it was completed to the same elevation of 30.568m at the top of the pressure relief cone.

[0071] The construction is divided into 3 layers and 4 sections, including:

[0072] First, construct and cast the ring beam of the pressure relief cone and the base of the partition wall;

[0073] When using the flip form construction method, the construction is carried out layer by layer with a construction height of 4.4 to 4.8 meters per layer. During the construction process, the scaffolding and formwork are constructed synchronously at an elevation slightly exceeding 30.568 meters, which is conducive to the convenience of sliding formwork assembly;

[0074] In the process of flip form construction, the tools and equipment used are relatively simple, with low technical requirements, and no need for professional slip form construction teams and equipment. It is suitable for the construction of components of various shapes and irregular sizes, and has a wide range of applicability. At the same time, by controlling the flipping speed of the formwork and the pouring amount of concrete, the accuracy of the geometric size and relative position of the structure can be guaranteed;

[0075] Furthermore, the scaffolding platform system was supported by the decompression cone and the partition wall. The templates on both sides of the decompression cone and the partition wall were removed, and the slipform system was reassembled again. The 400mm thick inner and outer wall slipforms of the silo that were temporarily removed due to the construction of the partition wall were restored, and the shear wall of the partition compartment exceeding +30.568m was assembled as a whole. The system was reinforced and connected in parallel to form an overall lifting platform system, so that the silo and the partition wall were slipformed at the same time, and lifted and completed synchronously to the warehouse top elevation. In this construction range, the following methods were adopted: Figure 5 In the connection form shown, the silo wall formwork and the shear wall formwork are integrally connected to complete the overall slipform construction to the silo top;

[0076] Specifically, to ensure the quality of construction, before the formal sliding, it is necessary to sort out the key points of construction quality control, strictly control the quality of concrete raw materials and admixtures, including multiple tests on the proportions of concrete sand and gravel grading, cement dosage, fly ash dosage, admixture type, etc., to accurately determine the best mix ratio so that the quality and performance of concrete meet the requirements of sliding form construction;

[0077] At the same time, the slump of concrete is controlled to be about 200mm, with good fluidity and workability. The retarder is appropriately added to make the initial setting time more than 8h. The total height of the formwork is 1.2m. The formwork is lifted once every 2 hours, and each time it is lifted 0.3m high. When it is removed from the formwork, it has been 8h since the pouring. The surface of the concrete removed from the formwork is promptly pressed and polished with original slurry to avoid color difference.

[0078] The sliding of the silo wall on the slipform platform is divided into several steps: initial sliding, normal sliding, intermediate stop sliding, and final sliding:

[0079] For the initial sliding, first sprinkle water inside the sliding formwork to moisten it, lay 30-50mm of mortar of the same strength grade as the concrete, and then pour the concrete in layers, with a thickness of about 300mm for each layer. According to the concrete solidification time, increase the jack stroke by 2-3 times after pouring, and observe the demoulding strength of the concrete. If the demoulding strength of the concrete is appropriate, turn to normal sliding. If the demoulding strength is too high or too low, adjust the sliding speed appropriately. It is more appropriate to control the demoulding strength of the concrete at about 0.2-0.4Mpa.

[0080] Normal sliding, after the initial sliding is normal, it will turn into normal sliding. The sliding will be carried out after the concrete pouring and vibration are completed. Each lifting is controlled within 300mm. During the lifting, steel bar welding, binding and support of the reserved hole template can be carried out. After the lifting is completed, the steel bar, prestressed steel bar and concrete construction will continue. After the concrete vibration is completed, it will be lifted again, and it will be repeated until the sliding stops or the sliding ends;

[0081] Stop sliding in the middle. According to the structural design or process requirements, there are processes such as changing the mold or installing process components. Stop sliding during the sliding process. When the upper mouth of the template slides to about 1 meter from the stop sliding elevation, start to slow down the sliding speed and perform accurate leveling and alignment work. Before sliding to 200 mm from the elevation, the leveling work is done so that the concrete can be evenly distributed in the end to ensure the accuracy of the stop sliding elevation. After stopping sliding, modify the mold or install the process components, and continue normal sliding after completion;

[0082] Final sliding: When the sliding rise approaches the final sliding elevation, the slipform system is leveled and adjusted. The final sliding process is the same as the intermediate stop sliding process. After the last layer of concrete is poured, it is moved every 0.5 to 1.0 hours to prevent the unsolidified concrete from sticking to the mold. The activity is stopped after the later poured concrete solidifies.

[0083] At the same time, the verticality of the sliding formwork construction is observed once every 1.0m of sliding, and the torsion is observed once every 0.6m of sliding. The verticality of the sliding is observed by full-time surveyors, and the observation data should be disclosed to the on-duty technicians in a timely manner. When the relative torsion at any 3m height is greater than 30mm, the technicians will determine the correction plan and the hydraulic lifting personnel will organize the implementation;

[0084] Furthermore, if deflection occurs during slipform construction, it can be adjusted by using methods such as climbing rod guidance method, external force torsion correction method and adjusting the concrete pouring sequence;

[0085] During the slipform assembly, four 5kg plumb bobs or plumb gauges are hung on the platform inside the silo at 90° intervals, and the center marks of the plumb bobs or nine-square target rings are made at the corresponding positions on the bearing surface. During the sliding, the relative mark offset and vertical difference of the plumb bobs or target rings are checked every meter of sliding to control the axis and verticality of the silo.
