They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0043] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. Throughout the description of this application, unless otherwise specified, "plurality" means two or more.

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0045] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0046] like Figures 1-16 A replaceable modular prefabricated pile foundation platform is shown, including a pile foundation drilling area platform, on which a modular panel 2 is detachably installed. The modular panel 2 includes multiple adjustable modular panels that can be moved to multiple positions and multiple fixed modular panels. The adjustable modular panel is arranged on the pile foundation hole position 3, and the fixed modular panel is arranged outside the pile foundation hole position 3.

[0047] Specifically during operation, the fixed module panel is fixed on the platform outside the pile foundation hole 3. The fixed module panel does not need to be moved after installation, and the adjustable module panel is fixed on the platform on the pile foundation hole 3. When one of the pile foundation holes 3 needs to be constructed, it is only necessary to remove the corresponding adjustable module panel to realize the construction operation of the pile foundation hole 3.

[0048] The main purpose of the present invention is to improve the flexibility and construction efficiency of large-scale pile group foundation construction, while effectively reducing on-site safety hazards and enhancing the image of civilized construction. The traditional pile foundation platform construction method is a construction process in which holes are reserved at the platform positions corresponding to all pile foundation holes. Compared with the present invention, there are many holes reserved on the drilling area platform, which greatly limits the movement of the rotary drilling rig, so that it can only move in a fixed direction and trajectory. At the same time, the storage and transportation of drill cuttings are also extremely inconvenient. The subsequent lowering of the steel cage and concrete pouring will also be affected by the surrounding holes, increasing the investment in personnel and some auxiliary facilities and equipment. For example, for concrete pouring, the present invention can use a concrete tank truck for direct pouring, while the traditional process requires the cooperation of a pump truck, resulting in poor construction flexibility, low construction efficiency, and a large amount of labor and equipment. The present invention simplifies the process, adopts modular prefabrication, and a process of moving and replacing during construction to better meet on-site construction requirements;

[0049] As a preferred embodiment, the modular prefabricated pile foundation platform also includes an auxiliary construction platform, which is located outside the pile foundation drilling area platform. A concrete panel 1 is provided on the auxiliary construction platform, and the modular panel 2 is flush with the top surface of the concrete panel 1.

[0050] It is worth mentioning that the auxiliary construction platform is generally used for the movement of workers and equipment, and plays an auxiliary construction role in the installation of the platform in the pile foundation drilling area.

[0051] As a preferred embodiment, the pile foundation drilling area platform and the auxiliary construction platform both include a support assembly 4, which includes a plurality of steel casings 403 arranged in a rectangular array, a first double-piece I-beam 402 being fixed on the steel casing 403, a platform Bailey beam 401 being fixed to the upper end of the first double-piece I-beam 402, and parallel connecting pipes 404 being fixed between adjacent steel casings 403, the modular panel 2 and the concrete panel 1 being both installed on the platform Bailey beam 401; each adjustable modular panel and each fixed modular panel are fixed to the platform Bailey beam 401 by a U-shaped clip, so as to realize the disassembly and installation of the modular panel 2.

[0052] It is worth noting that the first double-jointed I-beam 402 is arranged vertically to the platform Bailey beam 401, and the steel casing 403 is used to support the first double-jointed I-beam 402, while the first double-jointed I-beam 402 is used to support the platform Bailey beam 401, and the arrangement of the parallel connecting pipe 404 is used to enhance the stability of multiple steel casings 403.

[0053] Based on the above structure, when the pile foundation holes 3 are arranged in four rows, the adjustable module panel includes the third panel 203, the sixth panel 206, the first temporary replacement block 207 and the second temporary replacement block 208, and the fixed module panel includes the first panel 201, the second panel 202, the fourth panel 204 and the fifth panel 205;

[0054] The third panel 203 is arranged on the pile foundation hole positions 3 in the second and third rows, the sixth panel 206 is arranged on the pile foundation hole positions 3 in the first and fourth rows, the first temporary replacement block 207 is used to replace the sixth panel 206, and the second temporary replacement block 208 is used to replace the third panel 203. In an embodiment of the invention, the first and fourth rows have 9 pile foundation hole positions 3, and the second and third rows have 8 pile foundation hole positions 3, with a total of 34 pile foundation hole positions 3. The third panel 203 is on the pile foundation hole positions 3 in the second and third rows. One third panel 203 covers two pile foundation hole positions 3 at the same time, which is convenient for simultaneous replacement.

[0055] It is worth noting that the modular panels 2 are designed into 8 types of modules based on the distribution of the pile foundation holes 3. They are generally divided into two types: mobile and fixed. The panels at the 3 pile foundation holes are mobile, and the panels at the 3 non-pile foundation holes are fixed. According to this design concept, only two panels with holes need to be designed and swapped to achieve the purpose. According to construction needs, the maximum number of piles that can be constructed simultaneously is 6. Therefore, the entire platform only needs to process 6 panel modules with holes and constantly move and swap them to meet construction needs. Specifically: the modular panels 2 are divided into 8 types based on the distribution of the pile foundations, 2 of which are panel modules with holes, which are constantly swapped and coordinated during the pile foundation construction process. The modular panels 2 are divided into two types based on their functions: fixed and mobile. Among them, the first panel 201, the second panel 202, the fourth panel 204, and the fifth panel 205 are fixed, and the third panel 203, the sixth panel 206, the first temporary replacement block 207, and the second temporary replacement block 208 are mobile. The fixed modular panels do not need to be moved or replaced again after installation. The mobile third panel 203 and the sixth panel 206 need to be replaced to other positions before the pile foundation construction, and then returned to their original positions after the pile foundation construction is completed. The entire pile foundation construction process only requires replacement twice, and the first temporary replacement block 207 and the second temporary replacement block 208 will be continuously moved and replaced according to the pile foundation construction sequence.

[0056] Based on the above structure, both the first temporary replacement block 207 and the second temporary replacement block 208 are provided with mounting holes corresponding to the pile foundation hole positions 3 .

[0057] As a preferred embodiment, the third panel 203, the sixth panel 206, the first temporary replacement block 207, the second temporary replacement block 208, the first panel 201, the second panel 202, the fourth panel 204 and the fifth panel 205 all include a plurality of mutually parallel panel I-beams and a plurality of mutually parallel panel channel steels, the panel channel steels are fixed to the top of the panel I-beams, and the panel channel steels are arranged perpendicular to the panel I-beams.

[0058] Based on the above structure, the panel I-beam adopts I36 I-beam, the panel channel adopts [28 channel, and the I36 I-beam and [28 channel are connected by welding.

[0059] As a preferred embodiment, a second double-jointed I-beam 5 is fixed to the bottom of each of the third panel 203 and the sixth panel 206 , and the second double-jointed I-beam 5 is located on the pile foundation hole 3 .

[0060] Based on the above structure, both ends of the panel I-beams of the first panel 201 and the second panel 202 extend to the outside of their respective corresponding panel channel steels, and one end of the panel I-beams of the fourth panel 204 and the fifth panel 205 extends to the outside of their respective corresponding panel channel steels;

[0061] The two ends of the panel I-beam of the first panel 201 are staggered with one end of the panel I-beam on the fourth panel 204, the end of the panel I-beam of the second panel 202 is staggered with the end of the panel I-beam on the sixth panel 206, and the end of the panel I-beam of the fifth panel 205 is staggered with the end of the panel I-beam on the third panel 203. The staggered arrangement facilitates the welding operation between adjacent panel I-beams, thereby improving the overall stability.

[0062] The structure of the present invention is basically the same as that of a traditional pile foundation platform, but it adopts a prefabricated, movable and exchangeable design concept, that is, the drilling area platform panel is prefabricated in advance in a modular manner in different types and sizes, which can achieve the purpose of rapid installation and dismantling. During the pile foundation construction process, the panel modules are moved and exchanged according to the construction sequence and needs, so as to achieve the purpose of fast and flexible construction. The platform panels are designed into 8 types of modules according to the 3 distribution of pile foundation hole positions, which are generally divided into two types: mobile and fixed. Among them, the panels at the 3 pile foundation hole positions are mobile, and the panels at the 3 non-pile foundation hole positions are fixed. According to this design concept, only two panels with holes need to be designed and exchanged to achieve the purpose. According to the construction needs, the maximum number of piles to be constructed at the same time is 6. Therefore, the entire platform only needs to process 6 panel modules with holes for continuous movement and exchange to meet the construction needs.

[0063] The pile foundation platform adopts a prefabricated, movable and replaceable design concept, that is, the platform panels in the drilling area are prefabricated in advance in a modular manner with different types and sizes. After the platform lower structure is erected, the modular panel 2 is installed according to the designed position using lifting equipment. During the pile foundation construction process, the panel modules are moved and replaced according to the construction sequence and requirements using lifting equipment.

[0064] The present invention is suitable for the construction of a large number of pile group foundations. Large pile group foundations generally have a large number of pile foundations and a complex distribution. The use of traditional pile foundation platform technology results in a fixed drilling rig route and a single pile foundation construction sequence, which leads to poor construction flexibility and low construction efficiency.

[0065] The modular panels 2 of the drilling area platform of this project are divided into 8 types according to the distribution of pile foundations, of which 2 are panel modules with holes, which are constantly replaced to cooperate with the construction during the pile foundation construction. The modular panels 2 are divided into two types based on their functions: fixed and mobile. The first panel 201, the second panel 202, the fourth panel 204, and the fifth panel 205 are fixed, while the third panel 203, the sixth panel 206, the first temporary replacement block 207, and the second temporary replacement block 208 are mobile. The fixed modular panels do not need to be moved or replaced again after installation. The mobile third panel 203 and the sixth panel 206 need to be replaced to other locations before the pile foundation construction and returned to their original positions after the pile foundation construction is completed. The entire pile foundation construction process only requires two replacements, while the first temporary replacement block 207 and the second temporary replacement block 208 will be continuously moved and replaced according to the sequence of pile foundation construction. All modular panels 2 are made of I36 I-beams and [28 channel steels. When prefabricating modular panels 2, I36 I-beams and [28 channel steels are cut according to different size requirements, and then connected into a whole by welding according to the design drawings of the panel modules (the contact positions between the two are fully welded).

[0066] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by those skilled in the art on the basis of the present invention shall fall within the scope of protection required by the present invention.
