[0034] The principles and features of the present utility model will be described below with reference to the attached drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0035] As Figures 1 to 5 shown, a steel section positioning device for SMW method piles in this embodiment includes two positioning frames and multiple positioning steel pipes 3. Each positioning frame includes two first connecting steel pipes 1 and two second connecting steel pipes 2. The two first connecting steel pipes 1 and the two second connecting steel pipes 2 are connected to form a rectangular positioning frame. Both positioning frames are horizontally arranged and spaced up and down. The projection of the inner area of the upper positioning frame directly below coincides with the inner area of the lower positioning frame. One second connecting steel pipe 2 of the upper positioning frame is fixedly connected to the corresponding second connecting steel pipe 2 of the lower positioning frame through a positioning steel pipe 3, and the other second connecting steel pipe 2 of the upper positioning frame is fixedly connected to the corresponding second connecting steel pipe 2 of the lower positioning frame through a positioning steel pipe 3. All the positioning steel pipes 3 are vertically arranged.

[0036] As Figures 1 to 5 shown, one side wall of the first connecting steel pipe 1 in this embodiment is an insertion side wall, and two first insertion holes are arranged at intervals on the insertion side wall. The two first connecting steel pipes 1 are arranged in parallel and spaced apart, and the first insertion holes on the two first connecting steel pipes 1 are arranged opposite to each other one by one. The two ends of the second connecting steel pipe 2 are respectively inserted and fixed in a set of relatively arranged first insertion holes, and the second connecting steel pipe 2 is perpendicular to the first connecting steel pipe 1. By providing the first insertion holes, it is convenient to stably connect and fix the first connecting steel pipe and the second connecting steel pipe.

[0037] As Figures 1 to 5As shown, on the other side wall of the first connecting steel pipe 1 of this embodiment is a connecting side wall. The plugging side wall and the connecting side wall are adjacent and perpendicularly arranged. One end of the second connecting steel pipe 2 inserted into the first plugging hole is fixedly connected to the connecting side wall through a bolt 4. Connecting the second connecting steel pipe and the first connecting steel pipe through a bolt facilitates the disassembly and assembly between the first connecting steel pipe and the second connecting steel pipe.

[0038] Specifically, a connecting hole is provided at the connecting side wall corresponding to each first plugging hole. One end of the second connecting steel pipe 2 inserted into the first plugging hole is provided with a threaded hole corresponding to the connecting hole on the connecting side wall. The second connecting steel pipe 2 and the first connecting steel pipe 1 are fixedly connected by screwing the bolt 4 into the correspondingly arranged connecting hole and threaded hole.

[0039] Optionally, first plugging holes are provided on both opposite plugging side walls of the first connecting steel pipe 1, that is, the first plugging holes penetrate through the two plugging side walls of the first connecting steel pipe 1. The end of the second connecting steel pipe 2 can penetrate through the first connecting steel pipe 1.

[0040] As Figure 2 and Figure 5 shown, the two first plugging holes on the first connecting steel pipe 1 of this embodiment are respectively arranged near the two ends of the first connecting steel pipe 1. The distance between one first plugging hole and one end of the first connecting steel pipe 1 is a, and the distance between the other first plugging hole and the other end of the first connecting steel pipe 1 is b, and a = b. The two first plugging holes are symmetrically arranged, with a stable structure and capable of realizing stable support for the profiled steel.

[0041] As Figures 1 to 5 shown, a set of first channel steel connecting holes are provided on the connecting side wall between one end of the first connecting steel pipe 1 of this embodiment and the adjacent first plugging hole, and a set of second channel steel connecting holes are provided on the connecting side wall between the other end of the first connecting steel pipe 1 and the adjacent first plugging hole; the distance between a set of first channel steel connecting holes and one end of the first connecting steel pipe 1 is c, and the distance between a set of second channel steel connecting holes and the other end of the first connecting steel pipe 1 is d, and c = d. Using two sets of channel steel connecting holes with equal distances from the ends facilitates the cyclic and equidistant installation of the profiled steel. Specifically, the center point of a set of first channel steel connecting holes (for example, a set of first channel steel connecting holes includes two first channel steel connecting holes, and the midpoint between the two first channel steel connecting holes) is at a distance of c from one end of the first connecting steel pipe, and the center point of a set of second channel steel connecting holes (for example, a set of second channel steel connecting holes includes two second channel steel connecting holes, and the midpoint between the two second channel steel connecting holes) is at a distance of d from the other end of the first connecting steel pipe.

[0042] As Figures 1 to 3As shown in the figure, second insertion holes are provided on the lower side walls of the two second connecting steel pipes 2 of the upper positioning frame in this embodiment, and third insertion holes are provided on the upper side walls of the two second connecting steel pipes 2 of the lower positioning frame. The second insertion holes and the third insertion holes on the two second connecting steel pipes 2 arranged vertically and oppositely are arranged in one-to-one correspondence, and the upper and lower ends of the positioning steel pipe 3 are respectively inserted and fixed in a group of corresponding second insertion holes and third insertion holes. By providing the second insertion holes and the third insertion holes, it is convenient to stably connect and fix the positioning steel pipe and the second connecting steel pipe.

[0043] Specifically, second insertion holes can be provided on the upper and lower side walls of the two second connecting steel pipes 2 of the upper positioning frame, that is, the second insertion holes penetrate the upper and lower side walls of the second connecting steel pipe 2. Third insertion holes can be provided on the upper and lower side walls of the two second connecting steel pipes 2 of the lower positioning frame, that is, the third insertion holes penetrate the upper and lower side walls of the second connecting steel pipe 2. The upper and lower ends of the positioning steel pipe can penetrate the second connecting steel pipe 2 of the upper positioning frame and the second connecting steel pipe 2 of the lower positioning frame respectively.

[0044] As Figures 1 to 5 shown in the figure, one end of the positioning steel pipe 3 inserted into the second insertion hole is fixedly connected to the left side wall or the right side wall of the corresponding second connecting steel pipe 2 by a bolt 4, and one end of the positioning steel pipe 3 inserted into the third insertion hole is fixedly connected to the left side wall or the right side wall of the corresponding second connecting steel pipe 2 by a bolt 4. Using bolts to connect the positioning steel pipe and the second connecting steel pipe is convenient for the disassembly and assembly between the positioning steel pipe and the second connecting steel pipe.

[0045] As Figures 3 to 5 shown in the figure, there is one second insertion hole and it is provided at the middle position of the second connecting steel pipe 2 of the upper positioning frame, and there is one third insertion hole and it is provided at the middle position of the second connecting steel pipe 2 of the lower positioning frame.

[0046] As Figures 1 to 5 shown in the figure, the first connecting steel pipe 1, the second connecting steel pipe 2 and the positioning steel pipe 3 in this embodiment are all square steel pipes. The width of the first connecting steel pipe 1 is greater than the width of the second connecting steel pipe 2, and the width of the second connecting steel pipe 2 is greater than the width of the positioning steel pipe 3. Using square steel pipes with different widths has high structural strength and is convenient for assembly.

[0047] Specifically, the first connecting steel pipe 1 uses a square steel pipe with a length of 660 mm, a width of 100 mm, a height of 100 mm, and a thickness of 10 mm (length × width × height × thickness); the second connecting steel pipe 2 uses a square steel pipe with a length of 700 mm, a width of 80 mm, a height of 80 mm, and a thickness of 8 mm (length × width × height × thickness); the positioning steel pipe 3 uses a square steel pipe with a length of 500 mm, a width of 64 mm, a height of 64 mm, and a thickness of 8 mm (length × width × height × thickness); the bolt can be an M16 ordinary bolt.

[0048] When assembling the positioning device of this embodiment, first insert and fix a first connecting steel pipe and a second connecting steel pipe to form an L-shaped device. Similarly, assemble another L-shaped device, insert the two L-shaped devices into the remaining first insertion holes of each other for fixation to form a rectangular device, and repeat this process to obtain another positioning frame. Then insert two positioning steel pipes into the second insertion holes of the upper positioning frame and the third insertion holes of the lower positioning frame for connection and fixation to form a three-dimensional device.

[0049] The positioning device of this embodiment uses a positioning device composed of prefabricated steel pipes to position the profiled steel, which can be easily assembled and disassembled, reduce errors, achieve precise construction effects, and at the same time, without increasing unnecessary construction costs and reducing waste of human resources.

[0050] As Figures 1 to 5 shown, a positioning assembly of this embodiment includes two of the above-mentioned SMW method pile profiled steel positioning devices, and also includes a connecting channel steel 5. The two SMW method pile profiled steel positioning devices are arranged side by side. The two first connecting steel pipes 1 of the lower positioning frame of one SMW method pile profiled steel positioning device and the two first connecting steel pipes 1 of the lower positioning frame of the other SMW method pile profiled steel positioning device are arranged in one-to-one correspondence and coaxially. The coaxially arranged two first connecting steel pipes 1 are connected and fixed through the connecting channel steel 5. The two ends of the connecting channel steel 5 are respectively connected and fixed to the coaxially arranged two first connecting steel pipes 1 through bolts 4. The connecting channel steel is a connecting member for connecting the two devices and is also a key component for controlling the insertion position of the profiled steel. The central axis of the connecting channel steel 5 is parallel to the central axis of the connected first connecting steel pipe 1.

[0051] The positioning assembly of this embodiment is simple to process and convenient to operate. All components are connected by bolts, and the installation and disassembly are simple and fast. It can not only meet the positioning requirements of SMW method pile profiled steel, improve the appearance quality, but also minimize the impact on the working speed, and can be put into use once and recycled. Its application ability is relatively strong.

[0052] This embodiment also provides a positioning method, which is realized by using the above-mentioned positioning assembly, and includes the following steps: directly insert the first profiled steel 6 through GPS positioning, and assemble a SMW method pile profiled steel positioning device on the first profiled steel 6 so that the first profiled steel 6 is located in the area between the upper and lower frames of a SMW method pile profiled steel positioning device;

[0053] After assembling an SMW method pile steel section positioning device, connect the connecting channel steel 5 to an SMW method pile steel section positioning device, and assemble another SMW method pile steel section positioning device at the other end of the connecting channel steel 5. After the other SMW method pile steel section positioning device is assembled, insert the second steel section 7 into the area within the upper and lower frames of the other SMW method pile steel section positioning device;

[0054] After the second steel section 7 is inserted, remove the SMW method pile steel section positioning device on the first steel section 6 and move it to the position where the third steel section is to be inserted, and then connect it to the SMW method pile steel section positioning device on the second steel section 7 through the connecting channel steel 5, and cycle in turn until all the steel sections are installed.

[0055] The positioning method of this embodiment can effectively control the spacing between the steel sections. At the same time, the interaction between the upper and lower positioning frames of the positioning device can well ensure the vertical insertion of the steel sections and well control the vertical deviation angle. The two positioning devices cycle and turn, enabling all the steel sections to achieve a good positioning effect.
