Description

Technical Field

[0001] The utility model patent relates to the technical field of steel pipe column piles, and specifically, to a steel pipe plane position positioning device suitable for steel pipe column piles. Background Art

[0002] Before excavating a large-section foundation pit, the surrounding support piles and internal support system must be prepared. Due to the large cross-section of the foundation pit, the steel trusses used in the internal support system need to be supported by steel pipe column piles and brackets to ensure that the steel trusses are subjected to the same horizontal plane. Therefore, the plane position of the steel pipe column piles is required to be within the allowable range.

[0003] The foundation pit construction must follow the principle of "support first, then excavation". It is determined that the steel pipe column piles can only be constructed using underwater cast-in-place pile construction technology, and they must be positioned at the hole mouth to ensure that the plane position of the formed steel pipe column piles meets the requirements.

[0004] When the steel pipe column pile adopts the underwater cast-in-place pile construction technology, the steel pipe and the steel cage must be connected first, and then the connected steel pipe and steel cage are hoisted into the pile hole by lifting equipment, and then the concrete is poured underwater as a whole to form the pile. If the steel pipe and the steel cage are not effectively positioned during the hoisting process, the steel pipe will be offset, exceeding the standard value, affecting the subsequent construction of other structures.

[0005] In the prior art, when underwater cast-in-place piles are used for the construction of steel pipe column piles, there is a lack of effective steel pipe plane positioning devices during the hoisting and positioning of the steel pipes and steel cages, or the positioning is inaccurate, which can easily cause the steel pipes to shift, affecting the subsequent construction of the internal support system, which is not conducive to environmental protection and green construction.

[0037] 5) Fix the lower frame 200 horizontally on the steel casing 100, arrange the upper frame 300 horizontally on the lower frame 200, and fix the upper frame 300 and the steel casing 100, keep the cross position aligned with the pile center, and the upper frame 300 and the lower frame 200 form a secondary arrangement structure on the steel casing 100, and the arrangement position of the secondary arrangement structure is consistent with the arrangement position of the primary arrangement structure; the top of the steel pipe 400 is located below the secondary arrangement structure, and three plumbs 305 are connected to the two arc-shaped pieces 304;

[0038] 6) Adjust the position of the steel pipe 400 by lifting equipment until the three plumbs 305 are aligned with the outer circumference of the steel pipe 400, and then determine that the plane position of the steel pipe 400 is aligned with the projection position, and complete the plane position positioning of the steel pipe 400. Here, the plane position of the steel pipe 400 can be accurately positioned according to the principle of "uniqueness of the circumscribed circle of a plane triangle".

[0042] The tangent position 600 is welded and fixed to the trimming strip 302. Alternatively, other structural methods can be used for fixed connection.

The fixing member 500 has a positioning block, and the positioning block abuts against the outer periphery of the steel casing 100, so that the transverse bar 201 and the diameter bar 301 can be firmly fixed to the steel casing 100.

[0044] The upper part of the fixing member 500 has a sleeve hole for the transverse bar 201 or the diameter bar 301 to pass through. Bolts are passed through the upper part of the fixing member 500 to fix the fixing member 500 relative to the transverse bar 201 or the diameter bar 301. A positioning block is formed at the lower part of the fixing member 500.

[0045] After the position of the lower component is determined on the steel casing 100, the transverse bar 201 is inserted into the sleeve hole, the positioning block abuts against the outer periphery of the steel casing 100, and the fixing piece 500 is fixed to the transverse bar 201 by bolts to fix the lower frame 200 on the steel casing 100.

[0048] In this embodiment, a lower level 203 is provided on the transverse bar 201, and the position of the lower frame 200 on the steel casing 100 is adjusted until the lower level 203 shows that the lower frame 200 is in a horizontal state, and then the lower frame 200 is fixed to the steel casing 100.

[0049] In this embodiment, an upper level 306 is provided on the diameter bar 301, and the upper level 306 and the lower level 203 are staggered and arranged perpendicular to each other; the position of the upper frame 300 on the cylinder roller is adjusted until the upper level 306 shows that the upper frame 300 is in a horizontal state, and the cross position is aligned with the center position of the pile, and then the upper frame 300 is fixed to the steel casing 100.

[0050] The upper level 306 and the lower level 203 are arranged perpendicularly and staggered to each other, so that horizontal leveling can be achieved at multiple positions and orientations on the horizontal plane, so that the lower frame 200 and the upper frame 300 are arranged level.

[0051] In this embodiment, after the upper frame 300 and the lower frame 200 form the initial arrangement structure on the steel casing 100, and before the upper frame 300 and the lower frame 200 are disassembled, the butt-jointed intersection positions of the transverse bar 201 and the steel casing 100 are marked on the transverse bar 201 and the steel casing 100 to form a lower mark, and the butt-jointed intersection positions of the diameter bar 301 and the steel casing 100 are marked on the diameter bar 301 and the steel casing 100 to form an upper mark;

[0052] After the steel pipe 400 is lowered, the lower frame 200 is arranged on the steel casing 100 according to the lower mark, and the upper frame 300 is arranged on the steel casing 100 according to the upper mark, so that the arrangement position of the secondary arrangement structure is consistent with the arrangement position of the primary arrangement structure.

[0054] In this embodiment, there is an alignment gap between the plumb bob 305 and the top of the steel pipe 400, and the bottom of the plumb bob 305 is connected to a plumb bar 602 made of soft metal and extending to the outer circumference of the steel pipe 400.

[0055] During the process of adjusting the position of the steel pipe 400, the lifting equipment determines that the plane position of the steel pipe 400 is aligned with the projection position until the three plumb bobs 305 are aligned with the outer circumference of the steel pipe 400 and the inner curved surface of at least one bending piece 601 on each plumb bar 602 is attached to the outer circumference of the steel pipe 400.

[0056] By aligning three plumb bobs 305 with the outer circumference of the steel pipe 400 and providing a plumb bar 602, the verticality of the plumb bobs 305 can be ensured. The inner curved surface of at least one bending piece 601 on each plumb bar 602 is attached to the outer circumference of the steel pipe 400, and the alignment observation of the plumb bob 305 with the outer circumference of the steel pipe 400 can be further determined.
