Description

Technical Field

[0001] This application relates to the field of support structure technology, and in particular to an emergency-type steel pipe pile and cast-in-place pile collaborative support structure. Background Technology

[0002] In the field of building construction, especially in deep foundation pit, subway, and underground parking garage projects, the stability and safety of the support structure are crucial. While cast-in-place piles or sheet piles alone can be effective for support, their effectiveness is often insufficient under complex or abrupt geological conditions.

[0003] While cast-in-place piles are common, their stability and bearing capacity are limited when faced with complex geological conditions such as soft soil and sandy soil, which may lead to failure of the support structure and cause safety accidents. Steel pipe piles, with their high strength and high rigidity, can effectively support the soil under complex geological conditions, but their high construction cost and long construction period pose challenges. Utility Model Content

[0004] This application provides an emergency steel pipe pile and cast-in-place pile collaborative support structure to solve the problems of limited stability of support structures and high construction costs and long construction periods.

[0005] This application provides an emergency steel pipe pile and cast-in-place pile collaborative support structure, including: cast-in-place piles, a capping beam, anchor cables, a tie beam, a concrete beam, and steel pipe piles; the cast-in-place piles are arranged around the foundation on the side close to the stratum, and the capping beam is arranged on top of the cast-in-place piles; the tie beam is arranged on the side of the cast-in-place piles away from the stratum; one end of the anchor cable is connected to the tie beam, and the other end of the anchor cable passes through the cast-in-place pile and is fixedly connected to the stratum; one end of the steel pipe pile is inserted into the foundation near the tie beam, and the other end of the steel pipe pile is fixedly connected to the concrete beam, which is also fixedly connected to the cast-in-place piles.

[0006] The synergistic use of the steel pipe piles and the cast-in-place piles, combined with the reinforcement of the lintel and the anchor cables, significantly improves the stability and bearing capacity of the support structure, enabling it to better cope with complex geological conditions; provides timely and effective support for construction or buildings, ensuring project safety; greatly increases construction speed, reduces project delays, lowers overall construction costs; reduces material waste, simplifies the construction process, and reduces labor and material costs, resulting in good economic benefits and solving the problems of limited stability of support structures and high construction costs and long cycles.

[0007] Optionally, it also includes concrete beam anchor cables; one end of the concrete beam anchor cable is connected to the concrete beam, and the other end of the concrete beam anchor cable passes through the cast-in-place pile and is fixedly connected to the stratum, and the anchor cables and concrete beam anchor cables connected on the same cast-in-place pile are parallel to each other.

[0008] The concrete beam and the anchor cable are used to reinforce the cast-in-place pile, thereby improving the stability and load-bearing capacity of the overall structure; the parallel anchor cable and the concrete beam anchor cable can enhance the bending resistance and improve the structural stability.

[0009] Optionally, the concrete beam includes anchor holes, a bearing steel plate, and a concrete beam anchorage; the concrete beam has an L-shaped cross-section, the anchor holes are located inside the first arm of the concrete beam, the anchor holes are cylindrical, the end of the anchor hole away from the cast-in-place pile is inclined upwards, and the end of the anchor hole near the cast-in-place pile is inclined downwards; the bearing steel plate is located on the side of the first arm of the concrete beam away from the cast-in-place pile, the concrete beam anchorage is located on the bearing steel plate, one end of the concrete beam anchor cable is connected to the concrete beam anchorage, and the other end of the concrete beam anchor cable passes sequentially through the bearing steel plate, the anchor holes, and the cast-in-place pile to be fixedly connected to the stratum.

[0010] The concrete beam has an L-shaped cross-section. By setting the anchor holes at an angle, the anchor cable generates a strong compressive stress field in the soil and rock mass, thereby improving the stability of the entire structure, effectively dispersing the load, and reducing local stress concentration.

[0011] Optionally, there are multiple cast-in-place piles, which are evenly and vertically inserted around the foundation near the stratum; the diameter of the cast-in-place pile is 0.6-0.8m, the length of the cast-in-place pile is 8m, and the spacing between adjacent cast-in-place piles is 1.2m.

[0012] Determining the pile diameter and spacing ensures sufficient support and connection between piles, while also ensuring the pile diameter meets load-bearing requirements. Determining the pile length ensures the piles can penetrate deep into stable strata and provide adequate support.

[0013] Optionally, the waist beam includes a double-section channel steel, an inclined support plate, an anchor head bearing plate, and an anchor. The double-section channel steel has an H-shaped cross-section, and one side of the double-section channel steel is fixedly connected to the cast-in-place pile. The inclined support plate has a right-angled triangular cross-section, and the other side of the double-section channel steel is connected to the vertical surface of the inclined support plate. The anchor head bearing plate is disposed on the inclined surface of the inclined support plate, the anchor is disposed on the anchor head bearing plate, one end of the anchor cable is connected to the anchor, and the other end of the anchor cable passes sequentially through the anchor head bearing plate, the inclined support plate, the double-section channel steel, and the cast-in-place pile to be fixedly connected to the stratum.

[0014] The H-shaped double-channel steel is fixedly connected to the cast-in-place pile, enhancing the overall structural stability. The right-angled triangular cross-section design of the inclined support plate allows the waist beam to better distribute the load, reducing stress concentration and improving the structure's load-bearing capacity. The anchor head bearing plate is set on the inclined surface of the inclined support plate and connected to the anchor cable through the anchor, enhancing the waist beam's bending resistance and ensuring it is not prone to bending deformation under stress, thus improving the structure's safety and reliability. The clearly defined connection angle between the anchor cable and the anchor allows construction workers to more easily insert and fix the anchor cable in place, simplifying the construction process, improving construction efficiency and quality, and enhancing the overall structural stability and load-bearing capacity.

[0015] Optionally, the anchor head bearing plate has a rectangular structure; the thickness of the anchor head bearing plate is 20mm, and the dimensions of the anchor head bearing plate are 0.12×0.2m; the thickness of the inclined iron support plate is 10mm, and the dimensions of the inclined iron support plate are 0.2×0.2m.

[0016] The anchor head bearing plate adopts a rectangular structure, which can evenly distribute the load under stress, reduce stress concentration, and improve the overall stability and load-bearing capacity of the structure. The anchor head bearing plate is 20mm thick, which provides sufficient rigidity and strength to ensure that it is not easily deformed or damaged under high load conditions, thereby extending the service life of the structure. The anchor head bearing plate is 0.12×0.2m in size, which ensures that it meets functional requirements while minimizing material usage and maximizing economic benefits.

[0017] Optionally, the capping beam is a concrete capping beam; the size of the capping beam is 0.8×0.6m or 1.0×0.8m; the capping beam and the pile head of the cast-in-place pile are fixedly connected.

[0018] The capping beam has dimensions of 0.8×0.6m or 1.0×0.8m and possesses excellent bending resistance, maintaining the structural integrity under external forces. The fixed connection between the capping beam and the pile heads of the cast-in-place piles provides additional support, enhancing the structure's bending resistance; it also maximizes space utilization within a limited construction area, avoiding material waste; improving overall project efficiency and reducing costs.

[0019] Optionally, there are multiple steel pipe piles, which are evenly and vertically inserted around the foundation near the cast-in-place piles; the diameter of each steel pipe pile is 0.416m, the length of each steel pipe pile is 6.0m, and the spacing between adjacent steel pipe piles is 0.5m.

[0020] Multiple steel pipe piles are evenly and vertically inserted around the foundation near the cast-in-place piles, effectively distributing the load of the superstructure and improving the overall bearing capacity of the foundation. As a form of deep foundation, the steel pipe piles can transfer the load of the superstructure to deeper, stable soil layers, thereby reducing the risk of settlement and uneven settlement. The steel pipe piles have a diameter of 0.416m and a length of 6.0m, giving them high rigidity and strength, effectively resisting horizontal loads and bending moments. The spacing between adjacent steel pipe piles is 0.5m, forming a stable support network and further enhancing the overall structural stability.

[0021] Optionally, it also includes a slope protection concrete layer; the slope protection concrete layer includes a wire mesh and a concrete layer; the wire mesh is a 6mm wire mesh with a mesh size of 10cm×10cm; the concrete layer is a C20 concrete layer with a thickness of 8cm; the wire mesh is fixedly installed on the slope protection above the cap beam, and the concrete layer is installed on the slope protection surface.

[0022] The combined effect of the wire mesh and C20 concrete in the slope protection concrete layer significantly enhances slope stability. The wire mesh provides good tensile strength, while the C20 concrete provides high compressive strength; the combination makes the slope more stable under external forces, reducing the risk of landslides and collapses. The slope protection concrete layer also effectively prevents water erosion, weathering, and other natural factors from damaging the slope. The C20 concrete layer has good durability and corrosion resistance, enabling it to maintain its protective function for a long time and extending the service life of the slope.

[0023] Optionally, a replacement zone is provided at the bottom of the foundation; the depth of the replacement zone is 2.5m, and the interior of the replacement zone is C20 concrete.

[0024] Setting up a replacement zone at the bottom of the foundation and filling it with C20 concrete can significantly improve the overall bearing capacity of the foundation. C20 concrete has high strength and stiffness, effectively distributing the load of the superstructure and reducing the risk of foundation settlement and uneven settlement. The replacement zone is 2.5m deep, ensuring that the concrete layer is thick enough to support the load of the superstructure while providing good foundation stability. The use of C20 concrete further enhances the stability of the foundation, making the entire structure more stable and reliable under external forces. Furthermore, the replacement zone can make full use of underground space, improving land utilization.

[0025] As can be seen from the above technical solutions, this application provides an emergency steel pipe pile and cast-in-place pile collaborative support structure, including: cast-in-place piles, capping beams, anchor cables, waist beams, concrete beams, and steel pipe piles; the cast-in-place piles are arranged around the foundation on the side close to the stratum, and the capping beams are arranged on the top of the cast-in-place piles; the waist beams are arranged on the side of the cast-in-place piles away from the stratum; one end of the anchor cable is connected to the waist beam, and the other end of the anchor cable passes through the cast-in-place piles and is fixedly connected to the stratum; one end of the steel pipe pile is inserted around the foundation near the waist beam, and the other end of the steel pipe pile is fixedly connected to the concrete beams, and the concrete beams are also fixedly connected to the cast-in-place piles, so as to solve the problems of limited stability of the support structure and high construction costs and long construction period.

Detailed Implementation

[0032] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application.

[0033] To address the issues of limited stability of support structures and high construction costs and long construction periods, see [reference needed]. Figure 1 This application provides an emergency steel pipe pile and cast-in-place pile collaborative support structure, including: cast-in-place piles 10, capping beams 11, anchor cables 12, waist beams 13, concrete beams 21, and steel pipe piles 22; the cast-in-place piles 10 are arranged around the foundation on the side close to the stratum, and the capping beams 11 are arranged on the top of the cast-in-place piles 10; the waist beams 13 are arranged on the side of the cast-in-place piles 10 away from the stratum; one end of the anchor cables 12 is connected to the waist beams 13, and the other end of the anchor cables 12 passes through the cast-in-place piles 10 and is fixedly connected to the stratum; one end of the steel pipe piles 22 is inserted around the foundation near the waist beams 13, and the other end of the steel pipe piles 22 is fixedly connected to the concrete beams 21, and the concrete beams 21 are also fixedly connected to the cast-in-place piles 10.

[0034] It should be understood that the foundation is the soil or rock mass supporting the foundation of the building, and the stratum is located around the perimeter of the foundation. Specifically, taking a building construction project as an example, the location of the foundation area is first determined according to the drawings, and then the cast-in-place piles 10 are constructed to serve as the foundation of the entire support structure. After the cast-in-place piles 10 are completed, earthwork excavation is carried out, the pile heads of the cast-in-place piles 10 are removed and the capping beam 11 is installed, and then excavation continues to 1m below the waist beam 13. The cast-in-place piles 10 are reinforced using the waist beam 13 and the anchor cables 12 to improve the stability and bearing capacity of the structure. Excavation continues to the base of the foundation, and the steel pipe piles 22 are precisely driven to ensure that they are tightly integrated with the foundation, providing a stable foundation for the subsequent construction of the concrete beam 21. Finally, the concrete beam 21 is poured between the steel pipe piles 22 to form a stable connection structure.

[0035] The coordinated use of the steel pipe piles 22 and the cast-in-place piles 10, combined with the reinforcement of the waist beam 13 and the anchor cable 12, significantly improves the stability and bearing capacity of the support structure, enabling it to better cope with complex geological conditions; provides timely and effective support for construction or buildings, ensuring project safety; greatly increases construction speed, reduces project delays, lowers overall construction costs; reduces material waste, simplifies the construction process, and reduces labor and material costs, resulting in good economic benefits and solving the problems of limited stability of support structures and high construction costs and long cycles.

[0036] In some embodiments, a concrete beam anchor cable 15 is also included; one end of the concrete beam anchor cable 15 is connected to the concrete beam 21, and the other end of the concrete beam anchor cable 15 passes through the cast-in-place pile 10 and is fixedly connected to the stratum. The anchor cable 12 and the concrete beam anchor cable 15 connected on the same cast-in-place pile 10 are parallel to each other.

[0037] It should be understood that the concrete beam anchor cable 15 can be made of high-strength, corrosion-resistant anchor cable material to ensure the reinforcement effect on the concrete beam 21. During implementation, the installation and tensioning of the concrete beam anchor cable 15 must be carried out strictly in accordance with design requirements and construction specifications to ensure a tight bond between it and the concrete beam 21, thereby improving the stability and safety of the overall structure.

[0038] The concrete beam 21 and the anchor cable 12 are used to reinforce the cast-in-place pile 10, thereby improving the stability and load-bearing capacity of the overall structure. The parallel anchor cable 12 and the concrete beam anchor cable 15 can enhance the bending resistance and improve the structural stability.

[0039] In some embodiments, see Figure 3 The concrete beam 21 includes anchor holes 2101, a pressure-bearing steel plate 2102, and a concrete beam anchor 2103. The cross-section of the concrete beam 21 is L-shaped. The anchor holes 2101 are located inside the first arm of the concrete beam 21 and are cylindrical. The end of the anchor hole 2101 away from the cast-in-place pile 10 is inclined upward, and the end of the anchor hole 2101 close to the cast-in-place pile 10 is inclined downward. The pressure-bearing steel plate 2102 is located on the side of the first arm of the concrete beam 21 away from the cast-in-place pile 10. The concrete beam anchor 2103 is located on the pressure-bearing steel plate 2102. One end of the concrete beam anchor cable 15 is connected to the concrete beam anchor 2103, and the other end of the concrete beam anchor cable 15 passes through the pressure-bearing steel plate 2102, the anchor holes 2101, and the cast-in-place pile 10 in sequence and is fixedly connected to the stratum.

[0040] It should be understood that when the support structure of the cast-in-place pile 10 is not deep enough, the steel pipe pile 22 and the concrete beam 21 can be used in conjunction with the cast-in-place pile 10 for reinforcement. It is important to ensure that the driving depth of the steel pipe pile 22 is greater than 2 / 3 of the steel pipe pile 22, and the pouring quality of the concrete beam 21 should ensure that all the cast-in-place piles 10 and the steel pipe piles 22 can be firmly connected.

[0041] Specifically, the concrete beam 21 uses high-quality concrete materials and is mixed and poured strictly according to the mix proportions. During the pouring process, appropriate formwork support and vibration techniques are used to ensure the flatness and density of the concrete beam 21. After pouring, timely curing is carried out to ensure that the concrete beam 21 reaches the expected strength and stability. Furthermore, during construction, close monitoring of geological changes is necessary, and timely countermeasures must be taken to ensure construction safety.

[0042] In some embodiments, the side of the concrete beam 21 connected to the pressure-bearing steel plate 2102 is inclined toward the second arm of the concrete beam 21.

[0043] The inclined concrete beam 21 and the bearing steel plate 2102 not only jointly resist bending deformation and enhance the bending performance of the structure, but also make it easier to align and fix the concrete beam 21 and the bearing steel plate 2102 during installation, reducing construction difficulty and errors and improving construction efficiency.

[0044] In some embodiments, there are multiple cast-in-place piles 10, which are uniformly and vertically inserted around the foundation near the stratum; the diameter of each cast-in-place pile 10 is 0.6-0.8m, and the length of each cast-in-place pile 10 is 8m; the spacing between adjacent cast-in-place piles 10 is 1.2m.

[0045] Determining the pile diameter and spacing of the cast-in-place piles 10 ensures sufficient support and connection between the piles, while also ensuring the pile diameter meets load-bearing requirements. Determining the pile length of the cast-in-place piles 10 ensures they can penetrate deep into stable strata and provide sufficient support. During construction, rotary drilling rigs are suitable for drilling the cast-in-place piles 10 due to their advantages such as high drilling efficiency, good hole quality, and minimal impact on the surrounding environment.

[0046] In some embodiments, see Figure 2 The waist beam 13 includes a double-section channel steel 1301, an inclined support plate 1302, an anchor head bearing plate 1303, and an anchor 1304. The double-section channel steel 1301 has an H-shaped cross-section, and one side of the double-section channel steel 1301 is fixedly connected to the cast-in-place pile 10. The inclined support plate 1302 has a right-angled triangle cross-section, and the other side of the double-section channel steel 1301 is connected to the vertical surface of the inclined support plate 1302. The anchor head bearing plate 1303 is disposed on the inclined surface of the inclined support plate 1302, and the anchor 1304 is disposed on the anchor head bearing plate 1303. One end of the anchor cable 12 is connected to the anchor 1304, and the other end of the anchor cable 12 passes sequentially through the anchor head bearing plate 1303, the inclined support plate 1302, the double-section channel steel 1301, and the cast-in-place pile 10 and is fixedly connected to the stratum.

[0047] It should be understood that the double-section channel steel 1301 is formed by two sections of channel steel, which ensures that the waist beam 13 has sufficient strength and stability. The installation position of the waist beam 13 should be determined according to the design requirements to ensure an effective connection with the cast-in-place pile 10 and the capping beam 11. The anchor cable 12 is a prestressed anchor cable, and the specifications and quantity of the anchor cable 12 should be determined according to the design requirements and geological conditions. The installation of the anchor cable 12 should ensure an effective connection with the waist beam 13 and the cast-in-place pile 10, forming a complete reinforcement system.

[0048] The H-shaped double-channel steel 1301 is fixedly connected to the cast-in-place pile 10, which enhances the stability of the overall structure. The right-angled triangular cross-section design of the inclined support plate 1302 allows the waist beam 13 to better distribute the load, reduce stress concentration, and improve the load-bearing capacity of the structure. The anchor head bearing plate 1303 is set on the inclined surface of the inclined support plate 1302 and connected to the anchor cable 12 through the anchor 1304, which enhances the bending resistance of the waist beam 13, ensuring that it is not prone to bending deformation under stress, and improving the safety and reliability of the structure. The connection angle between the anchor cable 12 and the anchor 1304 is clear, making it easier for construction personnel to insert and fix the anchor cable 12 in place, simplifying the construction process, improving construction efficiency and quality, and enhancing the stability and load-bearing capacity of the overall structure.

[0049] In some embodiments, the anchor head bearing plate 1303 has a rectangular structure; the thickness of the anchor head bearing plate 1303 is 20mm, and the dimensions of the anchor head bearing plate 1303 are 0.12×0.2m; the thickness of the inclined iron support plate 1302 is 10mm, and the dimensions of the inclined iron support plate 1302 are 0.2×0.2m.

[0050] The anchor head bearing plate 1303 adopts a rectangular structure. The rectangular structure can evenly distribute the load under stress, reduce stress concentration, and improve the stability and load-bearing capacity of the overall structure. The anchor head bearing plate 1303 has a thickness of 20mm, which provides sufficient rigidity and strength to ensure that it is not easily deformed or damaged under high load conditions, thereby extending the service life of the structure. The anchor head bearing plate 1303 has dimensions of 0.12×0.2m, which ensures that it meets functional requirements while minimizing material usage and maximizing economic benefits.

[0051] In some embodiments, the capping beam 11 is a concrete capping beam; the size of the capping beam 11 is 0.8×0.6m or 1.0×0.8m; the capping beam 11 is fixedly connected to the pile head of the cast-in-place pile 10.

[0052] It should be understood that the concrete cap beam itself has high strength and stiffness, which can effectively distribute the load and reduce stress concentration. Through a firm connection with the pile heads of the cast-in-place piles 10, the overall load-bearing capacity of the structure is further enhanced, ensuring stability even under complex working conditions.

[0053] The capping beam 11 has dimensions of 0.8×0.6m or 1.0×0.8m and possesses excellent bending resistance, maintaining the structural integrity under external forces. The fixed connection between the capping beam 11 and the pile heads of the cast-in-place piles 10 provides additional support, enhancing the structure's bending resistance; it also maximizes space utilization within a limited construction area, avoiding material waste; improving overall project efficiency and reducing costs.

[0054] In some embodiments, there are multiple steel pipe piles 22, which are uniformly and vertically inserted around the foundation near the cast-in-place pile 10; the diameter of each steel pipe pile 22 is 0.416m, the length of each steel pipe pile 22 is 6.0m, and the spacing between adjacent steel pipe piles 22 is 0.5m.

[0055] It should be understood that positioning technology and piling equipment can be used to accurately drive the steel pipe piles 22. During the driving process, the verticality and driving depth of the steel pipe piles 22 are monitored in real time to ensure that the steel pipe piles 22 are tightly bonded to the foundation, providing a stable foundation for the subsequent construction of the concrete beam 21.

[0056] Multiple steel pipe piles 22 are evenly and vertically inserted around the foundation near the cast-in-place piles 10, effectively distributing the load of the superstructure and improving the overall bearing capacity of the foundation. As a form of deep foundation, the steel pipe piles 22 can transfer the load of the superstructure to deeper, stable soil layers, thereby reducing the risk of settlement and uneven settlement. The steel pipe piles 22 have a diameter of 0.416m and a length of 6.0m, giving them high rigidity and strength, effectively resisting horizontal loads and bending moments. The spacing between adjacent steel pipe piles 22 is 0.5m, forming a stable support network and further enhancing the overall structural stability.

[0057] In some embodiments, the system further includes a slope protection concrete layer 14; the slope protection concrete layer 14 includes a wire mesh and a concrete layer; the wire mesh is a 6mm wire mesh with a mesh size of 10cm×10cm; the concrete layer is a C20 concrete layer with a thickness of 8cm; the wire mesh is fixedly installed on the slope protection above the capping beam 11, and the concrete layer is installed on the slope protection surface.

[0058] It should be understood that during the implementation of the slope protection concrete layer 14, the slope surface needs to be cleaned to ensure it is free of debris and dust, which helps improve the adhesion between the shotcrete and the slope surface. Then, according to design requirements, 6mm wire mesh is hung on the slope surface, ensuring it is flat and secure. After the wire mesh is installed, C20 concrete is shotcreted using appropriate equipment to evenly spray the C20 concrete onto the slope surface to a thickness of 8cm. During the spraying process, parameters such as the concrete mix proportion and water-cement ratio must be carefully controlled to ensure the quality of the concrete and the spraying effect. After spraying, the concrete layer is cured. Appropriate methods are used for moisture retention and heat preservation to ensure the quality and strength of the concrete layer. Disturbance or damage to the concrete should be avoided during the curing period.

[0059] The wire mesh and C20 concrete in the slope protection concrete layer 14 work together to significantly enhance slope stability. The wire mesh provides good tensile strength, while the C20 concrete provides high compressive strength. The combination of these two elements makes the slope more stable under external forces, reducing the risk of landslides and collapses. The slope protection concrete layer 14 also effectively prevents water erosion, weathering, and other natural factors from damaging the slope. The C20 concrete layer has good durability and corrosion resistance, enabling it to maintain its protective function for a long time and extending the service life of the slope.

[0060] In some embodiments, a replacement zone 23 is provided at the bottom of the foundation; the replacement zone 23 has a depth of 2.5m and is filled with C20 concrete.

[0061] It should be understood that before the replacement zone 23 is set up, the foundation needs to be fully tested and evaluated to determine the scope and depth of the replacement.

[0062] Setting up the replacement zone 23 at the bottom of the foundation and filling it with C20 concrete can significantly improve the overall bearing capacity of the foundation. C20 concrete has high strength and stiffness, effectively distributing the load of the superstructure and reducing the risk of foundation settlement and uneven settlement. The replacement zone 23 is 2.5m deep, ensuring that the concrete layer is thick enough to support the load of the superstructure while providing good foundation stability. The use of C20 concrete further enhances the stability of the foundation, making the entire structure more stable and reliable under external forces. Furthermore, the replacement zone 23 can fully utilize underground space, improving land utilization.

[0063] As can be seen from the above technical solutions, this application provides an emergency steel pipe pile and cast-in-place pile collaborative support structure, including: cast-in-place pile 10, capping beam 11, anchor cable 12, waist beam 13, concrete beam 21, and steel pipe pile 22; the cast-in-place pile 10 is arranged around the foundation on the side close to the stratum, the capping beam 11 is arranged on the top of the cast-in-place pile 10; the waist beam 13 is arranged on the side of the cast-in-place pile 10 away from the stratum; one end of the anchor cable 12 is connected to the waist beam 13, and the other end of the anchor cable 12 passes through the cast-in-place pile 10 and is fixedly connected to the stratum; one end of the steel pipe pile 22 is inserted around the foundation near the waist beam 13, and the other end of the steel pipe pile 22 is fixedly connected to the concrete beam 21, and the concrete beam 21 is also fixedly connected to the cast-in-place pile 10, so as to solve the problems of limited stability of the support structure and high construction cost and long cycle.
