[0026] The high-position casing of the full-casing wall-protected bored pile hole and the interlocking structure of the working platform include an operating platform 1, a fixed sleeve 2 and a full casing 3. The fixed sleeve 2 is installed at the bottom center of the operating platform 1, and the full casing 3 is sleeved inside the fixed sleeve 2. The operating platform 1 includes four first U-shaped steels 4 that are perpendicular to each other. The interface of every two adjacent first U-shaped steels 4 is connected with the same second U-shaped steel 5. The second U-shaped steel 5 is perpendicular to the first U-shaped steel 4. A first I-shaped steel 6 is connected between every two adjacent second U-shaped steels 5. The four first I-shaped steels 6 and the second U-shaped steels 5 are all connected with a second I-shaped steel 7. Every two adjacent second I-shaped steels 7 are all connected with the same T-shaped steel 8. Every two adjacent T-shaped steels 8 are connected to each other, and guardrails 19 are installed on several T-shaped steels 8 and the second U-shaped steels 5.
[0027] By installing a fixed sleeve 2 on the operating platform 1 and sleeve the full sleeve 3 inside the fixed sleeve 2, the fixed sleeve 2 is positioned, which makes it convenient to fix the operating platform 1 on the top of the full sleeve 3, so that the device can have a good fit with the full sleeve 3, avoiding the safety hazard of high-position sleeve mouth operation; by connecting the second U-shaped steels 5 to a plurality of first U-shaped steels 4, and then installing the first I-shaped steel 6 on the second U-shaped steel 5, installing the second I-shaped steel 7 at both ends of the plurality of first I-shaped steels 6, and installing T-shaped steel 8 on the second I-shaped steel 7, the operating platform 1 is divided into two layers, which is convenient for meeting the different operating needs of the staff.
[0028] Specifically, in this embodiment, a third I-beam 9 is installed at the midpoint of each of the four first U-shaped steels 4, and the end of the third I-beam 9 away from the first U-shaped steel 4 is welded to the fixed sleeve 2, and a first triangular plate 10 is welded at the connection between the third I-beam 9 and the fixed sleeve 2, and this welding method adopts a double-sided full welding process.
[0029] By disposing the second I-shaped steel 7 , the fixing sleeve 2 can be installed on the first U-shaped steel 4 , and further connected to the entire operating platform 1 .
[0030] Specifically, in this embodiment, four second triangular plates 11 are connected between the second U-shaped steel 5 and the first I-shaped steel 6 , and the width and height of the second triangular plates 11 are both 150 mm, and the thickness is 10 mm.
[0031] By disposing the second triangular plate 11 , the second U-shaped steel 5 and the first I-shaped steel 6 can be connected via the second triangular plate 11 , thereby improving the connection strength and integrity of the components.
[0032] Specifically, in this embodiment, a hole 12 with a diameter of 40 mm is opened on the top of the second U-shaped steel 5, and a bow-shaped shackle 13 is rotatably installed on the hole 12, and a steel wire rope can be installed on the bow-shaped shackle 13.
[0033] By opening the hole 12 , the bow-shaped shackle 13 can be rotatably installed on the hole 12 , and then the entire operating platform 1 is hoisted by a steel wire rope, thereby realizing the lifting and lowering of the operating platform 1 .
[0034] Specifically, in this embodiment, a plurality of first B25 steel bars 14 are laid and welded at equal intervals between a plurality of T-shaped steels 8 and a plurality of second I-shaped steels 7 .
[0035] By laying the first B25 steel bar 14, the T-steel 8, the second I-steel 7 and the first B25 steel bar 14 form an upper operating surface of the operating platform 1, which can be used by construction workers to pour pile concrete.
[0036] Specifically, in this embodiment, a plurality of second B25 steel bars 15 are equidistantly laid and welded on the four first U-shaped steels 4 .
[0037] By laying the second B25 steel bars 15, the plane formed by the four first U-shaped steels 4 forms the lower operating surface of the operating platform 1, which can be used by construction workers to place steel cages, pouring conduits and orifice hoppers.
[0038] Specifically, in this embodiment, the fixed sleeve 2 includes a barrel 16 installed on four third I-beams 9, and a plurality of reinforcing plates 17 are circumferentially distributed on the inner curved surface of the upper end of the barrel 16. A skirt 18 is installed on the reinforcing plate 17, and the outer edge of the skirt 18 is connected to the barrel 16.
[0039] Due to the provision of several reinforcing plates 17, the skirt 18 is connected to the barrel 16, and the skirt 18 and the barrel 16 are connected through the reinforcing plates 17, so that the stability of the connection between the skirt 18 and the barrel 16 is greatly improved.
[0040] Specifically, in this embodiment, the skirt 18 is an arc-shaped steel plate with a width of 130 mm and a thickness of 10 mm, and is on the same straight line as the center of the cylinder body 16 .
[0041] By setting the skirt 18 , a limiting function can be provided for the fixed sleeve 2 , and the top of the full sleeve 3 is sleeved inside the fixed sleeve 2 , which plays a good role in limiting the position of the full sleeve 3 .
[0042] Specifically, in this embodiment, the outer diameter of the full sleeve 3 is 800 mm, the outer diameter of the fixed sleeve 2 is 1000 mm, the thickness of the barrel 16 is 10 mm, and the top width of the reinforcing plate 17 is 80 mm.
[0043] Thereby, a circular ring with an outer diameter of 1000 mm and an inner diameter of 910 mm can be formed between the barrel 16 and the reinforcing plate 17 , while the outer diameter of the entire sleeve 3 is 800 mm. Since 910 mm>800 mm, the entire sleeve 3 can be confined between several reinforcing plates 17 .
[0044] Specifically, in this embodiment, the inner diameter of the skirt 18 is 740 mm, the outer diameter is 1000 mm, and the skirt 18 is on the same straight line as the center of the entire sleeve 3.
[0045] Since the inner diameter of the skirt 18 is 740 mm, which is smaller than the outer diameter of the full sleeve 3 of 800 mm, the full sleeve 3 is restricted to a position below the skirt 18 in the fixed sleeve 2, thereby preventing the full sleeve 3 from being higher than the fixed sleeve 2.
[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
