Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method for constructing large-volume concrete using the skip-pour method. Background Technology

[0002] Mass concrete is widely used in existing buildings, such as large foundation slabs and reinforced concrete dams. Due to concrete's poor heat dissipation, the large amount of heat generated during the pouring of mass concrete is difficult to dissipate in time, leading to a significant temperature difference between the inside and outside of the concrete, generating substantial temperature stress. Furthermore, the low elastic modulus in the early stages of concrete pouring makes it prone to temperature cracking under the influence of temperature stress. To address this issue, projects often use post-pouring strips, but these strips generally suffer from problems such as difficulty in cleaning, delays in construction progress, and a tendency to crack.

[0003] To compensate for the shortcomings of post-pouring strips, more and more projects are turning to the skip-pouring method. The skip-pouring method uses the theory of "resistance" and "release" to divide large-volume concrete into blocks. The first block is poured in skip-pouring to allow time for stress to be released. The remaining blocks are poured in the later stages to use the concrete properties to resist smaller temperature shrinkage stress, thereby controlling stress and reducing cracking.

[0004] The size of the concrete blocks and the pouring process significantly affect the quality of concrete pouring. If the blocks are too large, temperature stress can easily cause cracking; if the blocks are too small, it increases the workload and delays the project. Developing an efficient pouring plan can effectively shorten the project time. Therefore, it is crucial to rationally divide the blocks and design a skip-pour construction process. Currently, in engineering projects, the block division is manually calculated by designers. This is problematic due to the large workload and, when encountering complex and irregular models, the division of the block shape and size is often not reasonable. Summary of the Invention

[0005] This invention provides a method for constructing large-volume concrete using a skip-pour method to solve the aforementioned technical problems.

[0006] To solve the above-mentioned technical problems, the present invention provides a method for constructing large-volume concrete using the skip-pour method, comprising the following steps:

[0007] Step 1: Region segmentation, including: obtaining the BIM model of the large-volume concrete, segmenting the BIM model into several independent regions based on thickness changes, and then segmenting each independent region into several quadrilateral regions.

[0008] Step 2: Block division, including: calculating the maximum non-splitting length of concrete within a preset area based on concrete material parameters, and dividing each quadrilateral region into several blocks based on the maximum non-splitting length;

[0009] Step 3: Generate the pouring route, including: planning the pouring route based on the adjacency relationship of each block and the pouring time interval between adjacent blocks, selecting different starting blocks to obtain other pouring routes, comparing the pouring time of each pouring route, and selecting the pouring route with the shortest time as the skip-pour construction route.

[0010] Preferably, step 1 includes:

[0011] Step 11: Import the BIM model of the large-volume concrete, identify the thickness of the concrete in the BIM model, and segment the BIM model based on the thickness change edges to obtain several independent regions;

[0012] Step 12: Determine the thickness of each independent region. Independent regions with a thickness greater than 1m are valid. Merge independent regions with a thickness less than or equal to 1m.

[0013] Step 13: Identify the edges of each individual region and extract the vertices;

[0014] Step 14: Divide the independent region into several quadrilateral regions based on its vertices.

[0015] Preferably, step 1 further includes step 15: performing a quality judgment on the quadrilateral regions generated by each segmentation. The quality judgment conditions include the number of internal angles of the quadrilateral, the difference in length of opposite sides, and the difference in length of adjacent sides. Based on the set qualified values, it is determined whether the generated quadrilateral region passes the quality judgment. Quadrilateral regions that fail the quality judgment are re-segmented until they pass the quality judgment.

[0016] Preferably, step 2 includes:

[0017] Step 21: Input the concrete material parameters in the project and calculate the maximum non-cracked compartment length of a 1m thick large-volume concrete.

[0018] Step 22: For quadrilateral regions with a thickness exceeding 1m, a reduction factor μ is used to control their dimensions;

[0019] Step 23: Extract the edges of each quadrilateral region to obtain the length of each side. Based on the maximum non-splitting compartment length, divide each side into r segments. Connect the opposite edges of each region to divide the region into several quadrilateral compartments.

[0020] Preferably, in step 21, the formula for calculating the maximum non-cracking section length Lx of a 1m thick mass concrete is:

[0021]

[0022] Where E is the elastic modulus of concrete; H is the thickness of the base slab or the height of the wall panel; C Xα is the horizontal resistance coefficient of the foundation or subgrade; α is the linear expansion coefficient of concrete; T is the overall temperature drop difference of the mutually constrained structures; ε p This represents the ultimate tensile strength of reinforced concrete.

[0023] Preferably, in step 22, the method for calculating the reduction factor μ is as follows: take a quadrilateral region with a thickness of 1m and a quadrilateral region with a thickness greater than 1m respectively, calculate the maximum temperature difference ΔT and ΔTi in the two cases respectively, and calculate the reduction factor μ = ΔT / ΔTi.

[0024] Preferably, the maximum temperature difference ΔT and ΔTi are calculated using the finite difference method or finite element software.

[0025] Preferably, in step 23, the number of segments for each edge is... in Indicates D / L i The calculation result is rounded up, where D is the side length of the quadrilateral region, and L is the radius of the radius. i This represents the maximum length of the warehouse in this area.

[0026] Preferably, step 2 further includes step 24: optimizing the storage block, the optimization method including at least: merging the small-area storage block with the adjacent storage block that meets the conditions, based on the minimum area of ​​the storage block; and adjusting the position of the contact point for storage blocks whose edges are in contact with two or more storage blocks at the same time.

[0027] Preferably, step 3 includes:

[0028] Step 31: Number all the blocks to obtain the volume of each block. Calculate the average area of ​​the blocks based on the total area of ​​the independent area and the number of blocks. Estimate the maximum number of blocks to be poured at one time, 'a', based on the maximum pourable volume. Group the blocks, with each block and its adjacent blocks forming a group. Let the pouring speed be 'a' and the pouring time interval between adjacent blocks be 'c'.

[0029] Step 32: Select the blocks for the first pour: Input the first pour time t1, select any block and freeze its adjacent blocks. Blocks in the frozen state cannot be selected; then select the next block and freeze its adjacent blocks, until a number of blocks are selected. At this point, all blocks are in three sets: the selected block set, the frozen block set, and the selectable block set; record the first pour completion time as T1 = t1 + A1 / a, and assign the thawing condition T to all frozen blocks. i >T1+c, and record the thawing time T1+c as t;

[0030] Step 33: Repeat step 32, output the nth pouring time, select the nth pouring quantity 'a' from the selectable block set, and record the pouring completion time T after each selection. iIn addition to the pouring volume, the corresponding frozen blocks are updated, and the current block thawing condition T is updated. i >t;

[0031] Step 34: After each time recording, first determine whether the current recording time meets the freezing conditions of the frozen blocks, unfreeze the blocks that meet the freezing conditions, and add them to the set of selectable blocks; then determine whether the selectable blocks are zero. If they are not zero, repeat step 33; if they are zero, continue to determine whether the frozen blocks are zero. If the frozen blocks are zero, output the recording time as the final pouring time. If the frozen blocks are not zero, increase the recording time and repeat step 33 until all blocks have been selected.

[0032] Step 35: Select a new starting block and repeat steps 32 to 34 to compare the obtained pouring time T with the previous pouring route until all routes are simulated. The pouring route with the shortest pouring time is obtained as the skip-pour method construction route.

[0033] Compared with existing technologies, the large-volume concrete skip-pour construction method provided by this invention has the following advantages:

[0034] 1. This invention identifies and divides deep pits and areas of different thicknesses in complex, large-volume concrete with irregular shapes, and performs compartment processing on each area according to given boundary conditions to obtain the optimal construction route, which greatly simplifies the compartment processing process before construction using the skip-compartment method.

[0035] 2. This invention can reduce the large amount of calculation work in the early stage of the skip-concrete method, divide large-volume concrete into zones based on thickness, and proposes a method for reducing the size of concrete of different thicknesses based on the maximum temperature difference, so as to make the size division of different areas more reasonable.

[0036] 3. This invention optimizes the storage block division by determining the area and contact, making the storage block division more reasonable;

[0037] 4. This invention automatically designs the construction route based on the block division results and automatically optimizes the best construction route, thus shortening the pouring construction period. Attached Figure Description

[0046] To illustrate the technical solutions of the invention in more detail, specific embodiments are listed below to demonstrate the technical effects; it should be emphasized that these embodiments are used to illustrate the invention and not to limit the scope of the invention.

[0047] The large-volume concrete skip-pour construction method provided by this invention, such as... Figure 1 As shown, it includes the following three steps: region segmentation, block division, and generation of pouring routes, wherein:

[0048] Step 1: Region segmentation, including: obtaining the BIM model of the large-volume concrete, segmenting the BIM model into several independent regions based on thickness changes, and then segmenting each independent region into several quadrilateral regions.

[0049] Step 2: Block division, including: calculating the maximum non-splitting length of concrete within a preset area based on concrete material parameters, and dividing each quadrilateral region into several blocks based on the maximum non-splitting length;

[0050] Step 3: Generate the pouring route, including: planning the pouring route based on the adjacency relationship of each block and the pouring time interval between adjacent blocks, selecting different starting blocks to obtain other pouring routes, comparing the pouring time of each pouring route, and selecting the pouring route with the shortest time as the skip-pour construction route.

[0051] This invention uses a graphic recognition algorithm to identify and partition deep pits and areas of different thicknesses in complex, large-volume concrete with irregular shapes. Based on given boundary conditions, each area is divided into sections. The construction route is designed according to given information such as construction team, road, and pouring volume. The construction time is automatically calculated to obtain the optimal construction route, which greatly simplifies the section processing process before the skip-section method construction.

[0052] In some embodiments, please refer to the following: Figure 2 Step 1 may include:

[0053] Step 11: Import the BIM model of the large-volume concrete, identify the thickness of the concrete in the BIM model, and segment the BIM model based on the thickness change edges to obtain several independent regions.

[0054] Step 12: Determine the thickness H of each independent region. Independent regions with thickness H > 1m are valid. Merge independent regions with thickness H ≤ 1m.

[0055] Step 13: Identify the edges of each individual region and extract the vertices.

[0056] Step 14: Divide the independent region into several (n) smaller quadrilateral regions based on its vertices.

[0057] In some embodiments, step 1 may further include step 15: performing a quality assessment on the quadrilateral regions generated each time through segmentation. The quality assessment criteria include the number of interior angles of the quadrilateral, the difference in length between opposite sides, and the difference in length between adjacent sides. Based on a set pass value, it is determined whether the generated quadrilateral region passes the quality assessment. Quadrilateral regions that fail the quality assessment are re-segmented until they pass the quality assessment. Specifically, a score for the quadrilateral region can be calculated based on the quality assessment criteria. The closer the number of interior angles of the quadrilateral is to 90°, the higher its score; the smaller the difference in length between opposite sides, the higher its score; the smaller the difference in length between adjacent sides, the higher its score. In other words, the closer it is to a square, the higher its score, thereby assessing the quality of the quadrilateral region.

[0058] This invention imports a BIM model of large-volume concrete and partitions the area based on identified thickness variation edges. Areas with a thickness of less than 1 meter are merged, while areas with a thickness of more than 1 meter are partitioned independently. Vertices of each area are extracted, and each area is divided into several smaller quadrilateral areas based on these vertices. The partitioning is then adjusted according to quality assessment criteria to make the partitioning more reasonable.

[0059] In some embodiments, please refer to the following: Figure 3 Step 2 may include:

[0060] Step 21: Input the concrete material parameters in the project and calculate the maximum non-cracking section length L of a 1m thick mass concrete. x The calculation formula is as follows:

[0061]

[0062] Where E is the elastic modulus of concrete; H is the thickness of the base slab or the height of the wall panel; C Xα is the horizontal resistance coefficient of the foundation or subgrade; α is the linear expansion coefficient of concrete; T is the overall temperature drop difference of the mutually constrained structures; ε p This represents the ultimate tensile strength of reinforced concrete.

[0063] After all parameters are entered, the system can automatically calculate the maximum non-fractured compartment length according to the predetermined formula.

[0064] According to the specifications, the spacing between storage blocks should not exceed 40m, therefore when L x When L > 40m, the maximum compartment length L is taken as 40m; when L x When the length is <40m, the maximum compartment length L = L x .

[0065] At this point, the area S of the storage block should not be greater than the area of ​​the square storage block with the maximum storage length. Li When the depth is greater than 40m, the maximum compartment area S ≤ 1600m². 2 When L i When ≤40m, S≤L i 2 =L x 2 .

[0066] Step 22: For quadrilateral regions with a thickness exceeding 1m, a reduction factor μ is used to control their dimensions. Specifically, the reduction factor μ is calculated as follows: For quadrilateral regions with a thickness of 1m and quadrilateral regions with a thickness greater than 1m, the maximum temperature difference ΔT and ΔT' in both cases are calculated using the finite difference method or finite element software. i The reduction factor μ is calculated to be μ = ΔT / ΔT. i .

[0067] Then L i =μL x When L i When L > 40m, L = 40m; when L i When ≤40m, L=L i =μL x Similarly, when L i When the depth is greater than 40m, the maximum storage area S in this region is... i ≤1600m 2 When L i When ≤40m, S i ≤L 2 =(μL) x ) 2 .

[0068] Step 23: Extract the edges of each quadrilateral region to obtain the length of each side. Based on the maximum non-splitting compartment length, divide each side into r segments. Connect opposite edges of each region to divide the region into several quadrilateral compartments. In some embodiments, the number of segments for each side is... in Indicates D / L i The calculation result is rounded up, where D is the side length of the quadrilateral region.

[0069] This invention calculates the maximum size and area of ​​a 1m thick concrete block and reduces the size and area of ​​the thicker area based on the maximum temperature difference of different thicknesses. It then sets the block size parameters for each area and divides the blocks into sections by connecting opposite edges. This improves the rationality of block segmentation, prevents cracking due to temperature stress, and facilitates subsequent construction.

[0070] In some embodiments, step 2 further includes step 24: optimizing the warehouse blocks. Specifically, to prevent excessively small warehouse blocks from increasing construction time, a warehouse block area determination condition is proposed. That is, warehouses with smaller areas than the maximum warehouse block area are merged with adjacent warehouse blocks that meet the condition. Please refer to this document for details. Figure 5a The specific implementation method is as follows:

[0071] First, calculate the total area S of the region. 总 The average area of ​​the warehouses in the region is obtained by combining the number of warehouses in that region, r. Judgment criterion: When any block s in this area is less than or equal to 35%. If the area of ​​a storage block is deemed too small, it is merged with its adjacent storage blocks, and the S value of the merged block is calculated. 合 Then, the area is determined, if S 合 Less than or equal to the maximum sub-warehouse area S in this region i If S 合 >S i If the condition is not met, the block will be merged with the next adjacent block, and the above judgment process will be repeated until the merger is successful. If there is no adjacent block that meets the conditions, the block merger will be abandoned.

[0072] To ensure the effectiveness of skip-batch construction, adjacency optimization can be performed on the blocks. This involves adjusting the position of the contact points for blocks whose edges simultaneously contact two or more other blocks. Please refer to this guide for details. Figure 5b Specifically, this invention limits the contact between adjacent silo edges. Ideally, one silo edge should only overlap with the edge of another silo. If one silo edge contacts two or more silo edges simultaneously, optimization can be performed. The specific steps are: extract the contact points between adjacent silo blocks, calculate the distance d from the contact point to the nearest edge endpoint of the silo, and if d ≥ 1 / 3L... iThen adjust the edge and move the contact point so that d < 1 / 3L i The edge of the storage block at that point is reconnected, and the storage block area is determined during the adjustment process to ensure that the adjusted storage block area is not greater than the maximum storage block area in that area.

[0073] This invention optimizes excessively small concrete blocks by providing area conditions and optimizes repeated contact boundaries based on given boundary conditions. After optimization, the block division results can be output, such as... Figure 4 As shown, this completes the warehouse allocation process.

[0074] In some embodiments, please refer to the following: Figure 6 Step 3 includes:

[0075] Step 31: Number all blocks to obtain the volume of each block. Calculate the average area of ​​each block based on the total area of ​​the independent region and the number of blocks. Then, estimate the maximum number of blocks (a) that can be poured in a single batch based on the maximum pourable volume. Group the blocks, with each block and its adjacent blocks forming a group. The main block can be denoted as n, and the adjacent blocks to the main block as in. Please refer to this step carefully. Figure 7 Let the pouring speed be a and the pouring time interval between adjacent blocks be c.

[0076] Step 32: Select the blocks for the first pour: Enter the first pour time t1, select any block and freeze its adjacent blocks. Blocks in the frozen state cannot be selected. Then select the next block and freeze its adjacent blocks, until a number of blocks of quantity 'a' are selected. Please refer to this step carefully. Figure 8 At this point, all blocks belong to three sets: the selected blocks set, the frozen blocks set, and the optional blocks set. The completion time of the first pour is recorded as T1 = t1 + A1 / a. Then, the thawing condition for all frozen blocks is assigned as T. i >T1+c, and denote the thawing time T1+c as t.

[0077] Step 33: Repeat step 32, output the nth pouring time, select the nth pouring quantity 'a' from the selectable block set according to the aforementioned principle, and record the pouring completion time T after each selection. i In addition to the pouring volume, the corresponding frozen blocks are updated, and the current block thawing condition T is updated. i >t.

[0078] Step 34: After each time recording, first determine whether the current recording time meets the freezing conditions for the blocks. Unfreeze the blocks that meet the freezing conditions and add them to the selectable block set. Then determine whether the selectable blocks are zero. If not, repeat the above steps; if they are zero, continue to determine whether the frozen blocks are zero. If the frozen blocks are zero, it means that all blocks have been selected, and output the recording time as the final pouring time. If the frozen blocks are not zero, increase the recording time and repeat the above steps until all blocks have been selected.

[0079] Step 35: Select a new starting block and repeat the above steps to compare the obtained pouring time T with the previous pouring route until all routes are simulated. The pouring route with the shortest pouring time is obtained as the skip-pour method construction route.

[0080] Based on the optimized compartmentalization results, this invention uses the time axis as a benchmark and simulates the construction route of the compartments multiple times by selecting, freezing, and unfreezing to automatically find the optimal construction route and shorten the pouring construction period.

[0081] In summary, the skip-pour construction method for large-volume concrete provided by this invention includes the following steps: Step 1: Region segmentation, including: acquiring a BIM model of the large-volume concrete, segmenting the BIM model into several independent regions based on thickness variations, and then segmenting each independent region into several quadrilateral regions; Step 2: Block division, including: calculating the maximum non-splitting length of concrete within a preset area based on concrete material parameters, and dividing each quadrilateral region into several blocks based on the maximum non-splitting length; Step 3: Generating pouring routes, including: planning pouring routes based on the adjacency relationship of each block and the pouring time interval between adjacent blocks, selecting different starting blocks to obtain other pouring routes, comparing the pouring time of each pouring route, and selecting the pouring route with the shortest time as the skip-pour construction route. This invention uses a graphic recognition algorithm to identify and partition deep pits and areas of different thicknesses in complex, large-volume concrete with irregular shapes. Based on given boundary conditions, each area is divided into sections. The construction route is designed according to given information such as construction team, road, and pouring volume. The construction time is automatically calculated to obtain the optimal construction route, which greatly simplifies the section processing process before the skip-section method construction.

Therefore, if these modifications and variations fall within the scope of the claims of the invention and their equivalents, the invention is also intended to include these modifications and variations.
