Abstract
Description
Technical Field
[0001] The utility model relates to the field of immersed tube construction, in particular to a cell partition board facilitating grouting, an immersed tube cell and a steel shell immersed tube structure. Background Art
[0002] For the "sandwich" structure of the steel shell immersed tube, in addition to replacing the similar formwork function of the traditional concrete immersed tube, the combination of the steel shell and concrete in force makes the overall structural strength further increased. Since this structure belongs to a new type of immersed tube tunnel structure, there is less publicly available information at present. The patents with publication numbers CN209114877U and CN215105508U respectively disclose the internal structure of the independent cell of the steel shell immersed tube and the setting of auxiliary process holes. However, when the external use conditions are different, such as when it is necessary to increase the load-bearing capacity of the cell, the above structures are difficult to fully meet the force requirements and need to be further optimized and improved.
[0003] In the conventional scheme, when the force increases, it is usually considered to increase the thickness of the inner and outer panels. Although the force can be increased, too large a panel thickness will lead to an increase in the difficulty of splicing and welding between steel plates in the later stage, and the weight of a single steel plate with the same area increases, and larger mechanical equipment needs to be increased during the assembly process to meet the assembly requirements.
[0004] Moreover, while increasing the bearing capacity of the cell, it is necessary to ensure the filling density of the concrete in the cell cavity. Summary of the Utility Model
[0005] The invention object of the utility model is to provide a cell partition board facilitating grouting, an immersed tube cell and a steel shell immersed tube structure aiming at the problems existing in the prior art, which can improve the load-bearing capacity of the cell and ensure the density of the concrete in the cell cavity.
[0006] In order to achieve the above object, the technical scheme adopted by the utility model is as follows:
[0007] A cell partition board facilitating grouting, comprising a partition board body, a through hole is arranged in the middle of the partition board body, and a notch is arranged at the corner of the partition board body.
[0008] For the cell partition board provided by the utility model, by arranging a through hole in the middle of the partition board body, the two sides of the partition board body can be communicated to form a channel for the flow of concrete, which is convenient for the flow of concrete in the cell cavity; the notch can form a gas circulation channel on both sides of the partition board body to avoid the situation of air closure during the flow of concrete, resulting in local hollowing. Especially at the corner position of the partition board body, it is often connected to the internal corner of the cell cavity in the structure, and the flow space of concrete is small. By arranging the notch at this position, the occurrence of air closure phenomenon can be avoided as much as possible, thereby improving the density of the concrete in the cell cavity;
[0009] In addition, during the heat release process of concrete setting, the partition body usually undergoes thermal expansion. The notch can leave sufficient space for the thermal expansion of the partition body, reducing its extrusion on the bin compartment and the impact on the stress distribution, which is beneficial to improving the structural strength of the bin compartment.
[0010] As a preferred solution of the present utility model, a plurality of first groove holes are provided on the upper side of the partition body.
[0011] When the concrete is filled at the top, as the filling is about to be completed, the flow space of the gas becomes smaller, and it is easier to have airtightness phenomenon and cause local hollowing. Providing a plurality of the first groove holes is beneficial to ensuring the smooth flow of the gas; and when the concrete on one side of the partition body is filled, the concrete can enter the other side through the first groove holes, which is beneficial to ensuring the overall filling density of the concrete in the bin compartment cavity.
[0012] As a preferred solution of the present utility model, at least one second groove hole is provided on the lower side of the partition body.
[0013] For the partition body with a longer length, it is difficult to meet the gas circulation requirements only by the notch provided at the lower corner. Therefore, one or more second groove holes can be added on the lower side of the partition body to assist the gas flow and prevent airtightness phenomenon, thereby improving the filling density of the concrete.
[0014] As a preferred solution of the present utility model, reinforcing rib plates are provided on the partition body, and the reinforcing rib plates are located on both sides of the through hole.
[0015] To ensure the flow of the concrete and facilitate the construction operation of the construction personnel, the opening size of the through hole is generally relatively large, which will cause a certain degree of decline in the strength of the partition body. Therefore, the reinforcing rib plates can be provided on both sides of the through hole to improve the structural strength of the partition body.
[0016] As a preferred solution of the present utility model, the area of the through hole is greater than 0.5 square meters.
[0017] In order to achieve the through flow of most of the concrete and facilitate the construction operation of the construction personnel from one side of the partition body to the other side, it is recommended that the area of the through hole be greater than 0.5 square meters, such as a circle with a diameter of 400 millimeters.
[0018] As a preferred solution of the present utility model, the shape of the through hole is circular, oval or oblong.
[0019] The above shapes are all arc chamfers, and stress concentration is not likely to occur, which can improve the structural strength of the partition body.
[0020] A submerged tube cell comprises a cell body, the cell body is provided with grouting holes and exhaust holes, and the cell body is provided with the cell partition as described above for grouting.
[0021] The immersed tube cell provided by the utility model adopts the cell partition that is convenient for grouting. The structural strength of the cell body can be improved by setting one or more partition bodies in the cell body, thereby improving the load-bearing capacity of the cell body in the area to meet the structural load-bearing requirements; at the same time, through holes and notches are set on the partition body to improve the fluidity of concrete during the grouting process of the cell body, and minimize the problems such as the increased difficulty of grouting caused by the addition of additional structures such as the partition body; compared with the use of conventional sealing partitions to divide the cell body into two or more independent cells, the cell body of this product does not need to add additional grouting holes, and can also reduce the number of grouting operations, which has the advantages of saving resources and simplifying the process.
[0022] As a preferred solution of the utility model, the partition body is fully or partially arranged in the width direction of the compartment body.
[0023] The full setting can increase the overall load-bearing capacity of the compartment body, while the partial setting can increase the load-bearing capacity of some parts of the compartment body with less material. The two setting methods can be flexibly selected according to the needs of the working conditions.
[0024] As a preferred solution of the utility model, the exhaust holes are arranged along the circumference of the cell body, the exhaust holes are 10-20 cm away from the side wall of the cell body, and some of the exhaust holes are arranged close to the side of the partition body away from the grouting hole.
[0025] After the concrete is injected from the grouting hole, it will form a slope distribution in the cell body with a high middle and low surroundings. The peripheral position of the cell body is usually filled with concrete last. The exhaust holes are arranged near the side wall of the cell body and circumferentially to ensure smooth gas flow during the entire pouring process;
[0026] The exhaust hole is arranged close to the side of the partition body away from the grouting hole, also considering the slope distribution of concrete in the cell body, which can prevent the exhaust hole from being blocked by concrete filling too early and causing the subsequent gas discharge flow path to be too long, thereby facilitating the smooth flow of gas and improving the density of concrete filling.
[0027] A steel shell immersed tube structure, comprising the immersed tube compartment as described above.
[0028] The steel shell immersed tube structure provided by the utility model can flexibly adjust the load-bearing capacity of the bin body according to the load-bearing requirements of different positions of the steel shell immersed tube structure due to the adoption of the above-mentioned immersed tube bin grid. Moreover, under the condition of increasing the load-bearing capacity, it can ensure the full and dense filling of concrete in the bin body, which is beneficial to the construction and popularization of the steel shell immersed tube.
[0029] In summary, due to the adoption of the above technical solutions, the beneficial effects of the utility model are as follows:
[0030] 1. For the bin grid partition provided by the utility model, by arranging a through hole in the middle of the partition body, the two sides of the partition body can be connected to form a channel for concrete flow, facilitating the flow of concrete in the bin cavity; the notch can form a gas circulation channel on both sides of the partition body, avoiding the situation of airtightness during the concrete flow process, which may cause local hollowing. Especially at the corner position of the partition body, it is often connected to the internal corner of the bin cavity in terms of structure, and the flow space of concrete is small. By setting the notch at this position, the occurrence of airtightness can be avoided as much as possible, thereby improving the compactness of concrete in the bin cavity; in addition, during the heat release process of concrete solidification, the partition body usually undergoes thermal expansion. The notch can leave a surplus space for the thermal expansion of the partition body, reducing its extrusion on the bin and the influence on the stress distribution, which is beneficial to improving the structural strength of the bin grid.
[0031] 2. In the preferred solution, several first groove holes are arranged on the upper edge of the partition body, which is beneficial to ensuring the smooth flow of gas; and when the concrete on one side of the partition body is filled, the concrete can enter the other side through the first groove holes, which is beneficial to ensuring the overall filling density of concrete in the bin cavity.
[0032] 3. For the immersed tube bin grid provided by the utility model, due to the adoption of the above-mentioned bin grid partition convenient for grouting, the structural strength of the bin body can be improved by arranging one or more partition bodies in the bin body, thereby improving the load-bearing capacity of the bin body in this area to meet the structural load-bearing requirements; at the same time, through holes and notches are arranged on the partition body, which can improve the fluidity of concrete during the grouting process of the bin body and minimize problems such as the increase in grouting difficulty caused by additional structures such as the partition body; compared with dividing the bin body into two or more independent bins by using conventional sealed partitions, the bin body of this product does not require additional grouting holes and can also reduce the number of grouting operations, having the advantages of saving resources and simplifying the process.
[0033] 4. The steel shell immersed tube structure provided by the utility model can flexibly adjust the load-bearing capacity of the bin body according to the load-bearing requirements of different positions of the steel shell immersed tube structure due to the adoption of the above-mentioned immersed tube bin grid. Moreover, under the condition of increasing the load-bearing capacity, it can ensure the full and dense filling of concrete in the bin body, which is beneficial to the construction and popularization of the steel shell immersed tube.

[0043] The present utility model will be described in detail below with reference to the accompanying drawings.
[0044] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0046] In the description of the embodiments, "several", "multiple", and "a number of" represent at least two. It can be any situation such as 2, 3, 4, 5, 6, 7, 8, 9, etc., or even more than 9.
[0047] Embodiment 1
[0048] As Figure 1 shown, a lattice partition board facilitating grouting includes a partition board body 10. A through hole 11 is provided in the middle of the partition board body 10, and a notch 12 is provided at the corner of the partition board body 10.
[0049] It can be understood that the partition board body 10 is a plate member with a certain thickness. By placing the partition board body 10 in the cavity of structures such as lattice cells and connecting the upper edge of the partition board body 10 to the upper inner wall of the structures such as lattice cells and the lower edge of the partition board body 10 to the lower inner wall of the structures such as lattice cells, the vertical load-bearing capacity of the structures such as lattice cells at this position can be improved. Compared with respectively arranging rib plates on the upper inner wall and the lower inner wall of the structures such as lattice cells, the partition board body 10 of the present utility model can simultaneously abut against the inner walls on both the upper and lower sides, and the effect of improving the load-bearing capacity of the structures such as lattice cells is more significant, and it is also more beneficial to control the stability and deformation amount of the structures such as lattice cells.
[0050] In addition to connecting with the upper and lower inner walls of the structures such as lattice cells, the partition board body 10 can also be connected to the left and right inner walls of the structures such as lattice cells. On the one hand, it can support the left and right inner walls and improve their horizontal load-bearing capacity. On the other hand, it can increase the constraint of the structures such as lattice cells on the partition board body 10 and prevent the partition board body 10 from becoming unstable.
[0051] A through hole 11 is provided in the middle of the partition board body 10. The opening size of the through hole 11 is relatively large and is used to communicate the two sides of the partition board body 10 in the thickness direction. When using the partition board body 10 to support structures such as lattice cells, the partition board body 10 will divide the internal space of the structures such as lattice cells. At this time, setting the through hole 11 can form a channel for the flow of concrete, enabling the concrete to flow from one side of the partition board body 10 to the other side through the through hole 11, facilitating the flow and filling of the concrete inside the structures such as lattice cells.
[0052] The corner of the partition body 10 is provided with a notch 12, such as Figure 1 As shown, the notch 12 can be set at the two corners below the partition body 10 and the two corners above the partition body 10. The shape of the notch 12 is generally preferably an arc shape. The size of the notch 12 is relatively smaller than the through hole 11. It is mainly used for the circulation of gas to prevent the gas from being unable to flow out during the concrete grouting process and causing air blocking. It can be understood that concrete has viscosity. During grouting, the concrete will form a slope distribution with a high middle and low surroundings. The corner position of the partition body 10, that is, the junction of the side wall of the structure such as the cell and the bottom or top surface, will be filled with concrete later than the middle position. At the same time, the space available for flow at this position is small, and it is more necessary to ensure smooth flow of gas. Therefore, the notch 12 is set at the corner of the partition body 10.
[0053] In addition, during the solidification and heat release process of concrete, the partition body 10 usually undergoes thermal expansion. The notch 12 can leave extra space for the thermal expansion of the partition body 10, reduce its impact on the cell and stress distribution, and help improve the structural strength of the cell.
[0054] In summary, the cell partition provided by the utility model can connect the two sides of the partition body 10 by setting a through hole 11 in the middle of the partition body 10, forming a channel for concrete flow, which is convenient for the flow of concrete in the cell cavity; the notch 12 can form a gas flow channel on both sides of the partition body 10 to avoid air stagnation during the flow of concrete and cause local hollowing, especially at the corner position of the partition body 10, which is often structurally connected to the inner corner of the cell cavity, and the flow space of concrete is small. Setting the notch 12 there can avoid the occurrence of air stagnation as much as possible, thereby improving the density of the concrete in the cell cavity.
[0055] In one or more embodiments, the upper end of the partition body 10 is provided with a plurality of first groove holes 13, and the first groove holes 13 can be as follows Figure 1 and Figure 5 The U-shaped hole shown is used for gas circulation and concrete to pass through; when concrete is filled to the top of a structure such as a cell, the concrete will reduce its fluidity due to the increase in its internal viscosity resistance, making it easier for air trapping to occur. In addition, the relatively long length of the partition body 10 makes it difficult to meet the gas circulation needs by relying solely on the notch 12 at the corner. Therefore, a number of first groove holes 13 are provided on the upper side of the partition body 10 to increase the gas circulation channel, which can ensure that the gas can flow out smoothly, prevent the air trap from causing local hollowing, and affect the compactness of the concrete filling inside the cell.
[0056] It can be understood that when grouting structures such as bin cells, concrete often enters from only one side of the partition body 10. The non-grouting side of the partition body 10 needs to be filled by the concrete on the grouting side flowing through the through-hole 11. However, there is still a certain distance between the upper edge of the through-hole 11 and the upper side of the partition body 10. When the liquid level of the concrete completely submerges the through-hole 11, it is often through the gravity extrusion between the concretes that the liquid level of the concrete on the non-grouting side can be raised. However, it is difficult to fill the position near the partition body 10 on the non-grouting side by the way of gravity extrusion. Therefore, another function of the first groove hole 13 is to allow the concrete to pass through and fill the remaining space on the non-grouting side to ensure the dense filling of the concrete in structures such as bin cells.
[0057] In one or more embodiments, at least one second groove hole 14 is provided at the lower side of the partition body 10. Similar to the upper side of the partition body 10, the lower side of the partition body 10 is also prone to airtightness due to its too long length. However, considering that the fluidity of the concrete at the bottom position is better and the probability of airtightness is relatively low, the number of the second groove holes 14 can be less. Usually, 1-3 can meet the ventilation needs. Of course, the specific number should be considered in combination with the specific working conditions.
[0058] In one or more embodiments, a reinforcing rib plate 15 is provided on the partition body 10. It can be understood that the opening of the through-hole 11 will cause a certain degree of decrease in the strength of the partition body 10. Generally, the larger the opening size, the greater the decrease in the structural strength. In order to make up for the strength loss, a reinforcing rib plate 15 can be provided on the partition body 10. The reinforcing rib plate 15 is preferably an arc-edge structure, which reduces stress concentration and improves the structural strength. For example, Figure 8 as shown; the reinforcing rib plates 15 can be symmetrically arranged on both sides in the thickness direction of the partition body 10. Its placement direction should be selected according to the main load-bearing direction of the bin cell. For example, in this embodiment, it is mainly used to increase the vertical load-bearing capacity of the bin cell, and the reinforcing rib plates 15 can be vertically arranged on both sides of the through-hole 11, such as Figure 1 shown.
[0059] In one or more embodiments, the opening area of the through-hole 11 is greater than 0.5 square meters. Such a size can not only enable most of the concrete to pass through, improving the fluidity of the concrete inside structures such as bin cells, but also allow construction workers to pass their hands or bodies through the through-hole 11 for welding operations or the installation of other structures.
[0060] In addition, the shape of the through-hole 11 can be circular, oval or oblong. These shapes have arc-shaped chamfers and are not prone to stress concentration, which is beneficial to improving the structural strength of the partition body 10. In this embodiment, the through-hole 11 is a circle with a diameter of 400 millimeters.
[0061] Embodiment 2
[0062] This embodiment provides a sunken tube bin cell, as Figures 2-4 shown, including a bin cell body 20. A grouting hole 21 and an exhaust hole 22 are provided on the bin cell body 20, and a bin cell partition board for facilitating grouting as described in Embodiment 1 is arranged inside the bin cell body 20.
[0063] The bin cell body 20 is a sealed cavity structure, and its internal cavity can be filled with concrete. In this embodiment, the bin cell body 20 is in the shape of a cuboid, including four side edges, a top surface and a bottom surface. A grouting hole 21 and several exhaust holes 22 are opened on the top surface of the bin cell body 20. The grouting hole 21 is used for the entry of concrete, and its size is relatively large, and preferably arranged at the middle position of the top surface. A section of grouting pipe can be connected above the grouting hole 21 to facilitate the filling of concrete; the exhaust hole 22 is used for the discharge of gas in the bin cell body 20, and its size is relatively smaller than that of the grouting hole 21. Similarly, a section of exhaust pipe can be connected above the exhaust hole 22. After the concrete emerges from the exhaust hole 22, a liquid level of a certain height can be formed in the exhaust pipe. On the one hand, the formation of the liquid level increases the pressure between the concrete below, which is beneficial to improving the filling density of the concrete inside the bin cell body 20. On the other hand, the formation of the liquid level can prevent the outside air from flowing back into the bin cell body 20, which is also beneficial to improving the filling density of the concrete inside the bin cell body 20.
[0064] In order to improve the load-bearing capacity of the bin cell body 20, a partition board body 10 as described in Embodiment 1 can be arranged inside the bin cell body 20. Among them, the number of partition board bodies 10 inside each bin cell body 20 can be one or more, and can be arranged parallel to the length direction of the bin cell body 20, or can be arranged parallel to the width direction of the bin cell body 20. In this embodiment, partition board bodies 10 parallel to the width direction of the bin cell body 20 are respectively arranged on both sides of the grouting hole 21, and the bin cell body 20 is divided into three interconnected grouting areas; it can be understood that the concrete directly flows into the middle grouting area from the grouting hole 21. When the liquid level height in the middle grouting area reaches the lower edge of the through hole 11, the concrete can flow into the two side grouting areas from the through hole 11. As the liquid level height is higher than the upper edge of the through hole 11, the continuous injection of concrete will generate a squeezing effect inside it. Under the squeezing effect, the liquid level height in the two side grouting areas can still rise. By forming a liquid level higher than the top surface of the bin cell body 20 by a certain height in the grouting pipe, or by using other equipment to squeeze the concrete, the two side grouting areas can be filled with concrete, and the excess concrete will overflow from the exhaust hole 22 into the exhaust pipe.
[0065] In summary, for the immersed tube compartment provided by the present utility model, due to the adoption of the above-mentioned compartment partition plate facilitating grouting, the structural strength of the compartment body 20 can be improved by arranging one or more partition bodies 10 in the compartment body 20, thereby enhancing the load-bearing capacity of the compartment body 20 in this area to meet the structural load-bearing requirements. At the same time, through holes 11 and notches 12 are provided on the partition body 10, which can improve the fluidity of the concrete during the grouting process of the compartment body 20 and minimize problems such as increased grouting difficulty caused by additional structures such as the partition body 10. Compared with dividing the compartment body 20 into two or more independent compartments by using a conventional sealed partition plate, the compartment body 20 of this product does not require additional grouting holes 21 and can also reduce the number of grouting operations, having the advantages of resource conservation and process simplification.
[0066] In one or more embodiments, the partition body 10 is arranged in full or in part in the width direction of the compartment body 20; for the full arrangement, as Figures 1-4 shown, both ends of the partition body 10 in the horizontal direction respectively abut / connect the two inner walls of the compartment body 20. At this time, the partition body 10 can support the compartment body 20 in the entire width direction of the compartment body 20; for the partial arrangement, as Figures 5-7 shown, one end of the partition body 10 in the horizontal direction abuts / connects the inner wall of the compartment body 20, and the other end is truncated at a certain position. At this time, the partition body 10 can partially enhance the load-bearing capacity of the compartment body 20. The above two setting methods can be flexibly selected according to the working conditions.
[0067] In one or more embodiments, the exhaust holes 22 are arranged along the circumferential direction of the compartment body 20, and the distance between the exhaust holes 22 and the side wall of the compartment body 20 is 10 - 20 cm. After the concrete is injected from the grouting hole 21, a slope-shaped distribution with a higher middle and lower around will be formed in the compartment body 20. Therefore, the peripheral position of the compartment body 20 is usually filled with concrete last. Arranging the exhaust holes 22 close to the side wall of the compartment body 20 and along the circumferential direction can ensure the smooth flow of gas during the entire pouring process and prevent airtightness at the corners.
[0068] In addition, some of the exhaust holes 22 are arranged close to the side of the partition body 10 away from the grouting hole 21, also considering the slope-shaped distribution of the concrete in the compartment body 20. If the exhaust holes 22 are arranged on the Figure 4 side of the partition body 10 close to the grouting hole 21 in the middle, after the middle grouting area is filled with concrete, the concrete will emerge from the exhaust holes 22. At this time, the gas in the area of the partition body 10 away from the grouting hole 21 needs to be discharged from the exhaust holes 22 at the corners, and the discharge path is relatively long. If the path is blocked by concrete in the middle, it is very easy for the area of the partition body 10 away from the grouting hole 21 to have concrete hollowing due to airtightness. Therefore, preferably, some of the exhaust holes 22 are arranged close to the side of the partition body 10 away from the grouting hole 21.
[0069] Embodiment 3
[0070] This embodiment provides a steel shell immersed tube structure, which uses the immersed tube compartment described in Embodiment 2. Due to the adoption of the above-mentioned immersed tube compartment, the load-bearing capacity of the compartment body 20 can be flexibly adjusted according to the load-bearing requirements of different positions of the steel shell immersed tube structure. And under the condition of increasing the load-bearing capacity, it can ensure the full and dense filling of the concrete in the compartment body 20, which is beneficial to the construction and popularization of the steel shell immersed tube.
