Description

Technical Field

[0001] This application relates to the field of cast-in-place pile construction technology, specifically to a concrete pouring platform for cast-in-place pile construction. Background Technology

[0002] During the construction of cast-in-place piles, the concrete pouring hopper and the construction guide pipe rest on the casing. Under the impact of the concrete pouring process, the casing may sink or shift, making it difficult to position the reinforcing cage. When the site geological conditions are poor and the surface fill is thick, the impact of the above construction method on the casing will be further increased, and in severe cases, it may lead to construction interruption.

[0003] The existing technology uses a support frame around the casing to support the reinforcing cage. First, this method is too crude for adjusting the height of the reinforcing cage, requiring constant adjustment of the support height or the installation of pads. Second, this method still requires placing the pouring hopper on the casing. Third, the impact on the reinforcing cage during pouring will still cause disturbance to the soil around the casing, making it unsuitable for construction sites with poor geological conditions. Summary of the Invention

[0004] This application provides a concrete pouring platform for cast-in-place pile construction, which solves the problem of disturbing the casing when pouring concrete on construction sites with poor geological conditions.

[0005] The technical solution of this application is as follows: A concrete pouring platform for cast-in-place pile construction includes a support column and an operating platform disposed at the top of the support column. The support column includes a lower first column section and an upper second column section. The interior of both the first and second column sections is hollow, and the surfaces of the first and second column sections are provided with insertion holes at several heights that can be matched with the pins. The operating platform has a filling hole at its center, a filling support for supporting the filling hopper is provided above the filling hole, a guide pipe for entering the grouting pile is provided below the filling hopper, and a hook is provided below the filling hole.

[0006] Furthermore, the filling support includes a circular support ring and a plurality of support legs distributed below the support ring.

[0007] Furthermore, the second column is hinged to the bottom of the operating platform so that the support column can be stored in the bottom of the operating platform.

[0008] Furthermore, the second column section and the bottom of the operating platform are provided with a support arm, and the support arm is provided with a hinge joint in the middle so that the support arm can be stored on one side of the operating platform along with the support column; When the support arm is extended, it forms a triangular space with the second column and the front side of the operating platform.

[0009] Furthermore, the first column section has a roller at the lower end of its outer wall on the outward side; The second column has a roller on the upper end of the outer wall on the outward side.

[0010] Furthermore, a ladder is provided between the front and rear support columns, and the upper end of the ladder is hinged to the operating platform so that the ladder can be flipped upwards and stored above the operating platform.

[0011] Furthermore, longitudinally arranged scissor lifts are hung between the left and right support columns, and longitudinally arranged scissor lifts are hung on both sides of the ladder on the front and rear support columns respectively; the scissor lifts are detachable structures.

[0012] Furthermore, the operating platform is surrounded by a fence.

[0013] Furthermore, a sling is connected to the upper end of the hook, and the tail end of the sling is driven by a winch.

[0014] Furthermore, a base is provided at the lower end of the first column section.

[0015] Due to the adoption of the above technical solution, the beneficial effects of this application are as follows: 1. This application raises the concrete pouring position by using a pouring platform, so the pouring hopper does not need to be placed on the casing, which can avoid the impact on the casing during the pouring process and prevent the casing from settling.

[0016] 2. This application uses a hook to erect the reinforcing cage, avoiding the continuous force exerted on the casing by the reinforcing cage resting on it. The hook-based method allows for more precise adjustment of the reinforcing cage's position within the casing. Traditional methods of using reinforcing bars as supports are affected by the spacing between the bars, leading to compromises in the cage's height. This application, by adjusting the cage height with a hook, can maintain it at any designed position without the need for additional shims. Attached Figure Description

[0019] Based on the background art, this application provides a concrete pouring platform for cast-in-place pile construction, including a support column 1 and an operating platform 2 disposed at the top of the support column 1; the support column 1 includes a lower first column section 1-1 and an upper second column section 1-2, both of which have hollow internal structures, and the surfaces of the first column section 1-1 and the second column section 1-2 are provided with insertion holes 3 at several heights that can be matched with pins; the operating platform 2 is provided with a grouting hole 4 at the center, a grouting bracket 6 for supporting a grouting hopper 5 is provided above the grouting hole 4, a guide pipe 7 for entering the interior of the cast-in-place pile is provided below the grouting hopper 5; and a hook 8 is provided below the grouting hole 4.

[0020] Both the first column section 1-1 and the second column section 1-2 are hollow structures to reduce weight. In this embodiment, the cross-sectional area of ​​the first column section 1-1 is smaller than that of the second column section 1-2, so that the second column section 1-2 can rest downwards on top of the first column section 1-1. When the second column section 1-2 is retracted, it rests on top of the first column section 1-1, and the two partially overlap. The first column section 1-1 and the second column section 1-2 are fixed together by a pin and a socket 3.

[0021] In practice, the operating platform 2 uses an aluminum alloy frame arranged in a grid pattern, which reduces weight while ensuring strength.

[0022] In this application, a circular opening is reserved at the center of the operating platform 2 as a filling hole 4, the purpose of which is to fix the guide tube 7 and prevent shaking during the filling process. In this application, the guide tube 7 is installed below the filling hopper 5, and then the filling hopper 5 is fixed on the filling bracket 6.

[0023] In a preferred embodiment of this application, the filling support 6 includes a circular support ring 6-1 and a plurality of support legs 6-2 distributed below the support ring 6-1. The circular support ring 6-1 can hold the filling hopper 5 in place to fix the filling hopper 5 throughout its entire range.

[0024] In a preferred embodiment of this application, the second column section 1-2 is hinged to the bottom of the operating platform 2, so that the support column 1 can be housed at the bottom of the operating platform 2. (See attached...) Figure 1 As shown, the second column section 1-2 is connected by a hinge and is stored inward at the bottom of the operating platform 2, which facilitates storage and saves space.

[0025] In one specific embodiment of the above implementation, the second column 1-2 and the bottom of the operating platform 2 are provided with a support arm 9. The support arm 9 has a hinge joint in the middle so that it can be stored on one side of the operating platform 2 along with the support column 1. When the support arm 9 is unfolded, it forms a triangular space with the second column 1-2 and the front side of the operating platform 2. When the second column 1-2 is retracted, the support arm 9 rotates to achieve retraction. The support arm 9 can support the second column 1-2 when it is unfolded, maintaining the stability of the operating platform 2. In a specific implementation, the support arm 9 is divided into two sections, one of which has a half-opening at the hinge knob, so that both sections of the support arm 9 can only be bent into the triangular space for retraction. The support arm 9 can be implemented using existing technology. In actual operation, the support column 1 is set at the four corners of the operating platform 2, and retracts simultaneously, which can lower the operating platform 2 to a plane.

[0026] In a preferred embodiment of the above embodiments, the first column section 1-1 is provided with a roller 10 at the lower end of its outer wall on the outward side; the second column section 1-2 is provided with a roller 10 at the upper end of its outer wall on the outward side. After the support column 1 is retracted, the roller 10 forms a walking mechanism at the lowermost end, facilitating platform movement.

[0027] In a preferred embodiment of the above embodiments, a ladder 11 is provided between the two front and rear support columns 1. The upper end of the ladder 11 is hinged to the operating platform 2, so that the ladder 11 can be folded upwards and stored above the operating platform 2. The ladder 11 is folded upwards and stored on the upper surface of the operating platform 2.

[0028] In a preferred embodiment of the above embodiments, a longitudinally arranged scissor lift 12 is suspended between the left and right support columns 1, and longitudinally arranged scissor lift 12 is suspended on both sides of the ladder 11, respectively, of the front and rear support columns 1; the scissor lift 12 is a detachable structure. (See attached diagram) Figures 1-3 As shown, the scissor lift 12 is a linked folding structure, which is hung on the side of the operating platform 2 by a hook to prevent construction personnel from accidentally entering under the operating platform 2.

[0029] In a preferred embodiment of this application, the operating platform 2 is surrounded by a fence.

[0030] In a preferred embodiment of this application, a sling is connected to the upper end of the hook 8, and the tail end of the sling is driven by a winch. The method of using the hook 8 to support the reinforcing cage allows for more precise adjustment of the cage's position within the casing. Traditional methods of supporting the reinforcing cage with reinforcing bars are affected by the spacing between the bars, leading to compromises in the cage's height. This application, by adjusting the reinforcing cage height using the hook 8, allows it to be maintained at any designed position without the need for additional shims.

[0031] In a preferred embodiment of this application, a base 13 is provided at the lower end of the first column section 1-1. The base 13 can increase the contact area, reduce the pressure, ensure the stability of the working platform, and avoid excessive pressure on the surrounding soil. In specific implementation, the base 13 should be a detachable structure and temporarily installed on the first column section 1-1 to facilitate the movement of the rollers 10.

[0032] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0033] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
