[0002] A bridge pier is a substructure that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation. It is generally made of cast concrete. However, when applied to river or sea bridges, the construction of the piers is difficult due to the influence of the geographical environment. The pier support structure is a structure used to support the construction of piers in difficult environments. The medium is isolated by setting up fences to ensure the completion of the construction of the piers. However, the fences in the prior art have problems such as structural instability and poor sealing. Utility Model Content

[0003] The utility model provides a bridge pier supporting structure and a steam oven, which solves the problems of insufficient stability and poor sealing of fences in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A pier support structure, characterized in that it includes a positioning assembly, the positioning assembly includes a steel pipe column and a Larsen steel sheet pile, the Larsen steel sheet piles are arranged to form a working chamber, and characterized in that a first support assembly and a second support assembly are arranged in the working chamber, the first support assembly is cast and formed, and the working chamber is isolated from the outside medium, thereby ensuring the sealing and stability of the working chamber, at least two second support assemblies are arranged, and the second support assemblies are welded to the surface of the Larsen steel sheet pile, and the stability and strength of the positioning assembly are improved by arranging the first support assembly and the second support assembly, thereby preventing the positioning assembly from being washed away due to excessive pressure of the medium.

[0006] Furthermore, a cap is provided in the working cavity, and a positioning assembly is connected to the cap by glue. The setting of the cap can improve the bearing capacity of the pier, enhance the stability, prevent the pier from tilting or shifting under the action of external force, improve the durability of the pier, and extend the service life of the bridge.

[0007] Furthermore, the second support assemblies are evenly distributed in the vertical direction, and the strength of the support is improved by arranging a reasonable number of second support assemblies to prevent the Larsen steel sheet piles from being destroyed due to excessive liquid pressure.

[0008] Furthermore, a steel mesh is provided in the same cap, and the steel mesh is a double-layer bidirectional setting, which enhances the bearing capacity of the structure. Through the criss-crossed double-layer steel mesh, the load from all directions can be more effectively dispersed and borne, the overall stability and safety of the structure can be improved, and the durability and crack resistance of the structure can be improved. The presence of the steel mesh can effectively restrain the shrinkage and temperature changes of the concrete, reduce the generation and expansion of cracks, thereby protecting the structure from external environmental factors and extending the service life of the structure.

[0009] Furthermore, a force transfer belt is provided on the same bearing platform, which is used to balance the stress. The force transfer belt can effectively transfer and disperse the load of the superstructure of the bridge, reduce the stress concentration at the bottom of the pier, and improve the stability and safety of the entire bridge structure.

[0010] Furthermore, oil felt is provided between the power transmission belt and the steel sheet piles. The power transmission belt is isolated from the steel sheet piles by the oil felt, which can effectively prevent moisture from penetrating into the steel sheet piles through the power transmission belt. The oil felt forms a lubricating layer between the power transmission belt and the steel sheet piles, which can reduce friction and wear between the two. This helps to maintain the integrity and stability of the power transmission belt, extend its service life, and reduce the frequency of maintenance and replacement. By isolating the oil felt from the steel sheet piles, the corrosion and wear of the power transmission belt can be reduced, thereby improving the durability of the entire elevated bridge pier structure.

[0011] Furthermore, the second support assembly includes a steel purlin, one end of which is welded to the Larsen steel sheet pile, and the other end is welded to the support steel. Welding is a strong connection method that can ensure that the connection has sufficient strength and rigidity. Through welding, the second support assembly and the support steel, steel sheet pile and other structures form a whole, which improves the overall stability and bearing capacity of the structure. This connection method can effectively transfer and disperse the load and reduce the stress and deformation of the structure.

[0012] Furthermore, a web is welded to the outer surface of the steel purlin, and the web is fixed to the outer surface of the steel purlin by welding or other connection methods, which can increase the cross-sectional area of ​​the steel purlin, thereby improving its ability to resist bending moment and shear force. This construction method enables the steel purlin to better disperse and transfer loads when subjected to external loads, reduce stress concentration, and improve the stability and safety of the overall structure.

[0013] Furthermore, a filling cavity is formed between the steel perimeter purlin and the Larsen steel sheet pile, and the filling cavity is used to fill the medium, which can effectively increase the friction between the steel perimeter purlin and the Larsen steel sheet pile, thereby enhancing the stability of the entire structure. This friction can resist external loads and maintain the integrity and stability of the structure.

[0014] Furthermore, the upper end surface of the pier is provided with a drainage ditch, which is made of a mixture of autoclaved lime sand bricks and cement mortar. The drainage ditch is used to remove excess impurities. The autoclaved lime sand bricks have high compressive strength and durability, and can resist erosion and wear from the external environment. At the same time, cement mortar, as an adhesive, can ensure a firm connection between bricks and improve the overall stability of the drainage ditch. The setting of the drainage ditch not only helps to remove excess impurities and moisture, but also prevents these substances from causing damage to the pier structure. By effectively removing impurities and moisture, the pier can be kept clean and dry, reducing the risk of corrosion and erosion. In addition, the drainage ditch can also prevent moisture from accumulating around the pier, thereby avoiding adverse effects on the bridge structure.

Through appropriate materials and processes, the first support assembly can be closely combined with the working chamber, thereby effectively isolating the external medium. At least two second support assemblies are provided and fixed to the surface of the Larsen steel sheet pile by welding. This connection method not only improves the overall stability of the positioning assembly, but also enhances its ability to resist external loads. When the medium pressure is too large, the second support assembly can effectively share the load and reduce the direct pressure on the positioning assembly, thereby preventing the occurrence of collapse.

Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0030] like Figures 1 to 7 As shown, the pier support structure of the utility model is mainly used to improve the strength and stability of the positioning assembly and improve the sealing performance by arranging the first support assembly 10 and the second support assembly 17 in the working chamber 21.

[0031] The utility model bridge pier support structure includes a positioning component, the positioning component includes a steel pipe column 11 and a Larsen steel sheet pile 12, and a PC pile can also be used. The steel pipe pile and the Larsen steel sheet pile 12 are used together. The Larsen steel sheet pile 12 is surrounded to form a working chamber 21. The Larsen steel sheet pile 12 divides the working chamber 21 into two inner and outer working chambers 21. The outer working chamber 21 is poured to form a first support component 10. The first support component 10 is a concrete support, and other medium materials can also be used. The concrete support has the advantages of a strong and durable structure, a strong bearing capacity, and a low maintenance cost. The first support component 10 is used to isolate the external medium from the internal working chamber 21 to prevent the medium from flowing into the internal working space. The inner working chamber 21 is provided with a second support component 17. A plurality of second support components 17 are evenly distributed in the vertical direction. The specific number is set according to the actual situation. This ensures that the steel plate 17 is in any position. The piles can get enough support to reduce the risk of deformation or destruction caused by uneven liquid pressure. The second support assembly 17 includes a steel purlin 16. The steel purlin 16 is arranged along the inner wall of the Larsen steel sheet pile 12. One end of the steel purlin 16 is welded to the Larsen steel sheet pile 12, and the other end is welded to the supporting steel 15 as a whole. Both ends of the supporting steel 15 are welded to the steel purlin 16 and fully welded. The fully welded weld is full and the structure is firm. The bearing capacity of the steel structure can be greatly improved, the strength of the welding part is enhanced, and the seismic resistance is good. Welding is a firm connection method that can ensure that the connection has sufficient strength and rigidity. Through welding, the second support assembly 17 and the supporting steel 15, Larsen steel sheet pile 12 and other structures form a whole, which improves the overall stability and bearing capacity of the structure. This connection method can effectively transfer and disperse the load and reduce the stress and deformation of the structure.

[0032] The outer surface of the steel purlin 16 is welded with a web 19, which is fixed to the outer surface of the steel purlin 16 by welding or other connection methods, which can increase the cross-sectional area of ​​the steel purlin 16, thereby improving its ability to resist bending moment and shear force. This construction method enables the steel purlin 16 to better disperse and transfer loads when subjected to external loads, reduce stress concentration, and improve the stability and safety of the overall structure. The web 19 is welded with a beam support 20, which is welded to the Larsen steel sheet pile 12, and can disperse and transfer the force of the beam support to the load-bearing object below. A filling cavity 18 is formed between the steel purlin 16 and the Larsen steel sheet pile 12, and the filling cavity 18 is used to fill the medium. When the bridge pier is cast, filling the medium such as crushed stone soil can effectively increase the friction between the steel purlin 16 and the Larsen steel sheet pile 12, thereby enhancing the stability of the entire structure. This friction can resist external loads and maintain the integrity and stability of the structure.

[0033] The working chamber 21 is provided with a cap 14, and the cap 14 is cast and connected with a positioning assembly. The setting of the cap 14 can improve the bearing capacity of the bridge pier, enhance stability, prevent the bridge pier from tilting or displacing under the action of external force, improve the durability of the bridge pier, and extend the service life of the bridge. The cap 14 is provided with a steel mesh, which is a double-layer bidirectional setting, which enhances the bearing capacity of the structure. Through the criss-cross double-layer steel mesh, the load from all directions can be more effectively dispersed and borne, the overall stability and safety of the structure can be improved, and the durability and crack resistance of the structure can be improved. The presence of the steel mesh can effectively restrain the shrinkage and temperature changes of the concrete, reduce the generation and expansion of cracks, thereby protecting the structure from external environmental factors and extending the service life of the structure.

[0034] A force transmission belt (not shown in the figure) is provided on the same bearing platform 14. The force transmission belt is used to balance stress. The force transmission belt can effectively transmit and disperse the load of the bridge superstructure, reduce the stress concentration at the bottom of the bridge pier, and improve the stability and safety of the entire bridge structure. Oil felt is provided between the force transmission belt and the steel sheet pile. The force transmission belt is isolated from the steel sheet pile by the oil felt, which can effectively prevent moisture from penetrating into the steel sheet pile through the force transmission belt. The oil felt forms a lubricating layer between the force transmission belt and the steel sheet pile, which can reduce the friction and wear between the two. This helps to maintain the integrity and stability of the force transmission belt, extend its service life, and reduce the frequency of maintenance and replacement. By isolating the oil felt from the steel sheet pile, the corrosion and wear of the force transmission belt can be reduced, thereby improving the durability of the entire elevated bridge pier structure.

[0035] The upper end surface of the pier is provided with a drainage ditch 13, which is made of a mixture of autoclaved lime sand bricks and cement mortar. The surface of the drainage ditch 13 is coated with cement mortar in a ratio of 1:2.5 (cement: sand). The drainage ditch 13 is used to remove excess impurities. The autoclaved lime sand brick has high compressive strength and durability, and can resist erosion and wear from the external environment. At the same time, cement mortar, as an adhesive, can ensure a firm connection between bricks and improve the overall stability of the drainage ditch 13. The setting of the drainage ditch 13 not only helps to remove excess impurities and moisture, but also prevents these substances from causing damage to the pier structure. By effectively removing impurities and moisture, the pier can be kept clean and dry, reducing the risk of corrosion and erosion. In addition, the drainage ditch 13 can also prevent moisture from accumulating around the pier, thereby avoiding adverse effects on the bridge structure.

[0036] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
