Description

Technical Field

[0001] This invention relates to the technical field of building construction, specifically to a positioning and correction platform for pipe insertion construction and a pipe insertion construction method. Background Technology

[0002] With the continuous development of the country, engineering construction technology is also constantly being updated. Currently, pipe insertion technology has reached a mechanized level, but this technology has a high cost and cannot be used as a priority for construction sites with small project volumes. In this case, a simpler and more applicable pipe insertion method can save costs for the project. Summary of the Invention

[0003] In order to solve one or more technical problems existing in the prior art, the present invention provides a positioning and correction platform for intubation construction and an intubation construction method.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A positioning and correction platform for cannulation construction includes a steel platform, positioning angle steel and anti-top steel. The steel platform forms a polygonal structure, and a through hole for cannulation is formed in the middle of the steel platform. Multiple positioning angle steels are fixed on the steel platform. One end of the positioning angle steel is fixed on the steel platform, and the other end of the positioning angle steel is located above the through hole and is used for positioning and correction of the cannulation. Multiple anti-top steels are also fixed on the steel platform. The anti-top steels are arranged vertically and their lower ends are fixed on the steel platform. The anti-top steels are parallel to the axis of the through hole. A horizontally extending limiting steel is fixed on the anti-top steel. The limiting steel is located above the through hole and is used for positioning and correction of the cannulation.

[0005] The beneficial effects of this invention are as follows: The positioning and correction platform for pipe insertion construction of this invention adopts a simplified platform device construction method instead of the traditional construction method, which improves material utilization, reduces construction costs, reduces on-site risk sources, reduces safety hazards, saves manpower, and shortens the construction period. The entire platform can position and correct the pipe during the pipe insertion process, making it less likely to tip over and reducing personnel injuries. The positioning angle steel serves two purposes: first, to accurately position the steel column pipe during insertion; and second, to prevent the steel column pipe from tipping over in all directions, minimizing large displacement deviations during construction and improving work efficiency. The anti-top steel is used to control verticality and elevation, improving project quality.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the steel platform includes four I-beams, which together form a square structure.

[0008] The beneficial effects of adopting the above-mentioned further solution are: by using four I-beams to weld together to form a square steel platform, the weight of the steel platform can be increased by using rebar anchoring and counterweighting, making the platform structure stable and reliable.

[0009] Furthermore, the four I-beams include two parallel first I-beams and two parallel second I-beams, with the two ends of one second I-beam fixed above one end of each of the two first I-beams, and the two ends of the other second I-beam fixed above the other end of each of the two first I-beams.

[0010] The beneficial effect of adopting the above-mentioned further solution is that this installation and fixing method makes the base structure formed by the four I-beams stable and reliable.

[0011] Furthermore, each of the second I-beams has at least two positioning angle steels at its upper end.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that at least two positioning angle steels are set on each second I-beam, which can provide stable support and positioning for the steel column insertion structure.

[0013] Furthermore, one second I-beam is provided with two first positioning angle steels arranged at an angle, and another second I-beam is provided with two second positioning angle steels arranged at an angle. The two first positioning angle steels and the two second positioning angle steels are arranged in a one-to-one correspondence, and the corresponding first positioning angle steels and second positioning angle steels are arranged on the same straight line.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that it enables the positioning angle steel to be evenly arranged, which facilitates stable force control and positioning of the steel column insertion pipe.

[0015] Furthermore, each of the I-beams is provided with a reverse-top steel section, which is located in the middle of the I-beam.

[0016] Furthermore, the four anti-top steel sections are located at the four corners of the square structure.

[0017] The beneficial effect of adopting the above-mentioned further scheme is that it makes the structure of the inverted top steel more stable and reliable.

[0018] Furthermore, the limiting steel is located above the positioning angle steel and is staggered from the positioning angle steel.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the steel column angle steel can be positioned and controlled from different directions without interference between the two.

[0020] Furthermore, both the anti-top steel and the limiting steel are made of I-beams.

[0021] A method for pipe insertion construction, using the aforementioned positioning and correction platform for pipe insertion construction, includes the following steps: excavating a pile foundation hole; fixing a steel platform around the pile foundation hole, ensuring the through hole of the steel platform coincides with the axis of the pile foundation hole; trial-installing the pipe in the pile foundation hole and then removing the pipe; pouring concrete in the pile foundation hole; then hoisting and lowering the pipe into the concrete of the pile foundation hole; and finally installing positioning angle steel and anti-top steel on the steel platform, ensuring the other end of the positioning angle steel is aligned with the outer wall of the pipe. An operating gap is reserved between the insertion tube and the limiting steel and the outer wall of the insertion tube. The insertion tube is then inserted into the concrete of the pile hole, so that the reverse lug plate on the outer wall of the insertion tube is located diagonally below the limiting steel. Then the insertion tube is rotated so that the reverse lug plate on the outer wall of the insertion tube is directly below the limiting steel. After the insertion tube is inserted into place, column concrete is poured into the insertion tube, and yellow sand is poured into the pile hole outside the insertion tube. After the concrete has initially set, the steel platform can be removed from the pile hole.

[0022] The beneficial effects of this invention are: the cannulation construction method of this invention not only improves material utilization rate, but also reduces construction costs, reduces on-site risk sources, reduces safety hazards, saves manpower and shortens the construction period.

[0037] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0038] like Figures 1-12 As shown in the figure, a positioning and correction platform for cannulation construction in this embodiment includes a steel platform, positioning angle steel, and anti-top steel 5. The steel platform forms a polygonal structure, and a through hole for the cannula 7 to pass through is formed in the middle of the steel platform. Multiple positioning angle steels are fixed on the steel platform. One end of the positioning angle steel is fixed on the steel platform, and the other end of the positioning angle steel is located above the through hole and is used for positioning and correction of the cannula 7. Multiple anti-top steel 5s are also fixed on the steel platform. The anti-top steel 5s are arranged vertically and their lower ends are fixed on the steel platform. The anti-top steel 5s are parallel to the axis of the through hole. A horizontally extending limiting steel 6 is fixed on the anti-top steel 5. The limiting steel 6 is located above the through hole and is used for positioning and correction of the cannula 7.

[0039] In this embodiment, the positioning angle steel can be welded to the steel platform, and the anti-top steel 5 can also be welded to the steel platform. For example, insertion holes can be made on the steel platform, and the lower end of the anti-top steel 5 can be inserted into the insertion holes before welding and fixing.

[0040] like Figures 1-2 As shown, the steel platform in this embodiment includes four I-beams, which together form a square structure. By using four I-beams welded together to form a square structure, the weight of the steel platform can be increased by using rebar reinforcement and counterweight, thus ensuring the platform structure is stable and reliable.

[0041] like Figures 1-2 As shown, the four I-beams in this embodiment include two parallel first I-beams 1 and two parallel second I-beams 2. The two ends of one second I-beam 2 are respectively fixed above one end of each of the two first I-beams 1, and the two ends of the other second I-beam 2 are respectively fixed above the other ends of each of the two first I-beams 1. This installation and fixing method ensures that the base structure formed by the four I-beams is stable and reliable.

[0042] like Figures 1-2 As shown, each of the second I-beams 2 in this embodiment has at least two positioning angle steels at its upper end. The presence of at least two positioning angle steels on each second I-beam 2 provides stable support and positioning for the steel column insertion structure.

[0043] like Figures 1-2 As shown, in this embodiment, one second I-beam 2 is provided with two first positioning angle steels 3 arranged at an angle, and another second I-beam 2 is provided with two second positioning angle steels 4 arranged at an angle. The two first positioning angle steels 3 and the two second positioning angle steels 4 are arranged in a one-to-one correspondence, and the corresponding first positioning angle steels 3 and second positioning angle steels 4 are arranged on the same straight line. This balanced arrangement of the positioning angle steels facilitates stable force application and positioning control for the steel column insertion pipe. Specifically, the straight line containing the two first positioning angle steels 3 is the first straight line, and the straight line containing the two second positioning angle steels 4 is the second straight line. The first straight line and the second straight line intersect, and the intersection point is located on the central axis of the steel platform; preferably, the first straight line and the second straight line can be arranged perpendicularly.

[0044] like Figures 1-2 As shown, each of the I-beams in this embodiment is provided with a reverse top section 5, and the reverse top section 5 on each I-beam is located in the middle of the I-beam.

[0045] like Figures 1-2 As shown, in this embodiment, the four anti-top steel sections 5 are located at the four corners of the square, making the structure of the anti-top steel sections more stable and reliable.

[0046] like Figures 1-2 As shown, in this embodiment, the limiting steel 6 is located above the positioning angle steel and is staggered with it. The steel column angle steel can be positioned and controlled from different angles without interference between the two.

[0047] Specifically, the limiting steel sections 6 on the two opposing anti-top steel sections 5 are located on the same straight line A, and the limiting steel sections 6 on the other two opposing anti-top steel sections 5 are located on the same straight line B. Straight lines A and B intersect, and the intersection point is located on the central axis of the steel platform. Preferably, straight lines A and B can be set perpendicularly. Preferably, the vertical projection of straight line A can be set at the midpoint between the first and second straight lines. The entire structure of the positioning angle steel and anti-top steel sections is stable and reliable, and can effectively correct and position the steel column insertion pipe.

[0048] Specifically, both the anti-top steel 5 and the limiting steel 6 are made of I-beams.

[0049] An optional solution in this embodiment is to use HW250X250 I-beams welded to form the steel platform. The size of the entire foundation platform is designed according to the pile diameter requirements. The welds must be full, and the overlap length between the two steel sections must be no less than 250mm. The steel platform serves as the foundation of the entire device, its function being to fix the entire frame, ensure the platform's flatness and positioning, and prevent displacement during construction that could lead to pipe misalignment. The positioning angle steel uses angle steel no smaller than L150×5, positioned at the corners of the steel platform. Its function is to control the elevation and horizontal position of the pipe during insertion, ensuring the accuracy of the insertion elevation and avoiding difficulties in subsequent construction. The top-mounted steel support uses HW150X150 steel, welded at the centerline of the four sides of the platform base. The height of the top-mounted support is controlled between 1000mm and 1200mm for easy standing and operation by personnel. The length of the upper limit steel of the anti-top steel is the same as the length of the anti-top ear plate. Its function is to adjust the verticality and elevation after the insertion tube is in place, so as to ensure the construction quality of the insertion tube.

[0050] In this embodiment, the positioning and correction platform for pipe insertion construction involves welding inverted top plates and marking the center crosshair position on the pipe sidewalls according to design requirements after the pipe is transported to the site. After completion, it is placed in the hoisting area of ​​the work surface for later use. Mechanical drilling is performed according to design requirements. After cleaning and acceptance, the reinforcing cage is placed, and underwater concrete is poured to the design elevation. The simple pipe insertion platform is installed and fixed before hoisting the pipe. After the pipe is inserted to the design elevation, it is temporarily fixed with positioning angle steel to ensure the accuracy of the horizontal position and elevation. Jacks are used at the top and bottom of the limiting steel position for verticality adjustment. After the verticality and center point meet the design and specification requirements, the limiting steel is welded and fixed at the limiting steel position and the inverted top plate position, and the jacks are removed. After the installation work is completed, yellow sand is used to backfill the area from the working surface to the pile top elevation to ensure that the pipe does not shift during the concrete curing period. After curing, the pipe insertion platform device is removed.

[0051] The positioning and correction platform for pipe insertion construction in this embodiment uses a simplified platform device instead of traditional methods, which improves material utilization, reduces construction costs, minimizes on-site risks and safety hazards, saves manpower, and shortens the construction period. The entire platform can position and correct the pipe during installation, preventing it from tipping over and reducing personnel injuries. The positioning angle steel serves two purposes: first, to accurately position the steel column pipe during insertion; and second, to prevent the steel column pipe from tipping over, minimizing large displacement deviations and improving work efficiency. The anti-reverse steel section controls verticality and elevation, improving project quality.

[0052] This embodiment also provides a cannulation construction method, which is implemented using the positioning and correction platform for cannulation 7 described above, such as... Figures 3 to 12 As shown, the procedure includes the following steps: excavating pile foundation hole 9, as... Figure 1 As shown, the steel platform is fixed to the ground 93 around the pile foundation hole 9, and the through hole of the steel platform is aligned with the axis of the pile foundation hole 9, as shown. Figure 2 As shown; Figure 5 and Figure 6 As shown, after the insertion tube 7 is installed in the pile foundation hole 9, it is removed, and concrete 92 is poured into the pile foundation hole 9 through the guide hopper 91; as Figures 7-9 As shown, the insertion tube 7 is then hoisted and inserted into the concrete 92 of the pile foundation hole 9. Then, positioning angle steel and anti-top steel 5 are installed on the steel platform, ensuring that an operating clearance is provided between the other end of the positioning angle steel and the outer wall of the insertion tube 7, and between the limiting steel 6 and the outer wall of the insertion tube 7. Figure 10 As shown, continue inserting the insertion tube 7 into the concrete 92 of the pile foundation hole 9, so that the reverse lug plate 8 on the outer wall of the insertion tube 7 is located obliquely below the limiting steel 6. Then rotate the insertion tube 7 so that the reverse lug plate 8 on the outer wall of the insertion tube 7 is directly below the limiting steel 6. After the insertion tube 7 is inserted into place, pour the column concrete 92 into the insertion tube 7, and pour yellow sand into the pile foundation hole 9 outside the insertion tube 7, as shown. Figure 11 As shown; after the concrete has initially set (92%), the steel platform can be removed from around the pile foundation hole 9. Figure 12 As shown.

[0053] The cannulation construction method in this embodiment improves material utilization, reduces construction costs, minimizes on-site risk sources, reduces safety hazards, saves manpower, and shortens the construction period. This embodiment uses a simple cannulation platform device to replace mechanized construction methods, simplifying the construction process, ensuring construction quality while reducing construction costs, minimizing the investment in large on-site equipment, reducing on-site hazards, and lowering safety risks.
