Description

Technical Field

[0001] This utility model belongs to the field of cast-in-place pile technology, and in particular relates to a safety protection and duct transport device for cast-in-place piles. Background Technology

[0002] With the continuous development of urban construction, rotary drilling rigs for cast-in-place piles have become an important method of foundation treatment and are widely used in various construction projects. Rotary drilling rigs advance through the soil using rotating drill rods and bits to form pile holes of a certain diameter and depth. The following safety hazards exist during the construction of cast-in-place piles.

[0003] (1) Most of the safety protection devices at the openings on site are simple protections (using steel pipes, fasteners or welded steel bars for edge protection). The protections are placed on the upper part of the openings and are very easy to tilt and overturn under lateral thrust. In addition, there are certain gaps in the protections and the soil around the openings is slippery, which makes it easy for safety problems to occur. (2) The existing protection and guide pipe device for cast-in-place piles are separate, which is not conducive to safe construction. After the cast-in-place pile is drilled, the hole is covered with a mesh to prevent people from falling in. However, the protection needs to be removed during the casting process. When workers use the guide pipe to carry out concrete pouring operations in the hole, there is a safety hazard between the guide pipe and the hole. (3) Depending on the on-site grouting materials, the pipe size is not the same, and the pipe needs to be replaced frequently, which leads to slow construction progress.

[0004] In summary, existing methods for constructing cast-in-place piles suffer from safety insecurity, inconvenience, and uneconomical practices in terms of safety protection and duct transportation, which do not conform to green construction practices. Therefore, this utility model designs a safety protection and duct transportation device for cast-in-place piles. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a safety protection and duct transport device for cast-in-place piles, which solves the problems of weak protection and slow construction progress of traditional on-site safety protection devices for cast-in-place piles.

[0006] This utility model achieves the above-mentioned technical objectives through the following technical means.

[0007] A safety protection and guide pipe transportation device for cast-in-place piles includes a casing, a cover plate, a cover plate plug, a guide pipe disc, and a guide pipe. The cover plate is an integrally molded structure, with the main body being a hollow cylinder. A cover plate settlement platform is provided on the upper inner wall of the main body, and a circular groove is provided at the bottom of the main body. Hooks are symmetrically installed on the lower part of the main body. When no pouring operation is being performed, the cover plate plug is inserted into the cover plate settlement platform. Buckles are symmetrically installed on the upper part of the casing. The cover plate is snapped onto the top of the casing through the bottom circular groove, and further fixed to the casing through the hooks and buckles. During the pouring operation, the guide pipe disc is inserted into the cover plate settlement platform. The guide pipe disc is an integrated molding structure, with the main body being a hollow cylinder. The upper inner wall of the main body is equipped with the guide pipe disc settlement platform, and the top of the guide pipe disc settlement platform is equipped with two freely opening and closing "U"-shaped guide pipe disc cover plates. A hollow disc is installed at the bottom of the guide pipe. During the pouring operation, the guide pipe is inserted from top to bottom to the target position after the guide pipe disc cover plates are opened. After the guide pipe disc cover plates are closed, the guide pipe is clamped and fixed.

[0008] Furthermore, the cover plate settling platform is hollow inside and its inner diameter is larger than the inner diameter of the main body of the cover plate, and the guide plate settling platform is hollow inside and its inner diameter is larger than the inner diameter of the main body of the guide plate; the inner diameter of the hollow disc is the same as the inner diameter of the guide, and the outer diameter of the hollow disc is smaller than the inner diameter of the cover plate, smaller than the inner diameter of the guide plate, and larger than the inner diameter of the ring formed by the guide plate and cover when closed.

[0009] Furthermore, the cover plug is cylindrical, with its height being the same as the height of the cover settling platform, and its inner diameter matching the inner diameter of the cover settling platform.

[0010] Furthermore, a lifting rope is also installed on the upper part of the guide plate cover.

[0011] Furthermore, the outer diameter of the main body of the guide plate is matched with the inner diameter of the cover plate settling platform, and the height is the same as the height of the cover plate settling platform.

[0012] Furthermore, two hinges are symmetrically installed on the top of the guide plate. Both guide plate covers are connected to the guide plate through the hinges. When the two guide plate covers are closed, they form a ring that covers the top of the guide plate settling platform. The inner diameter of the ring is smaller than the inner diameter of the guide plate and larger than the outer diameter of the guide plate. The outer diameter of the ring is larger than the inner diameter of the guide plate settling platform.

[0013] This utility model has the following beneficial effects: (1) The casing and the cover plate are tightly connected by buckles and hooks, which improves safety; (2) The safety protection device of the cast-in-place pile is combined with the guide pipe device, which reduces the gap between the guide pipe and the hole and reduces the danger during the pouring operation; (3) The size of the guide pipe plate can be changed according to the size of the guide pipe, which can reduce the use of materials and increase construction efficiency.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0017] The safety protection and duct transport device for cast-in-place piles described in this utility model includes a safety protection part and a duct transport part.

[0018] like Figures 1 to 4 As shown, the safety protection section includes a protective sleeve 1, a cover plate 3, and a cover plate plug 7. Buckles 2 are symmetrically installed on both sides of the upper part of the protective sleeve 1. The cover plate 3 is an integrally molded structure, with the main body being a hollow cylinder. A cover plate settling platform 4 is provided on the upper inner wall of the main body; the cover plate settling platform 4 is hollow inside, and its inner diameter is larger than the inner diameter of the main body. A circular groove 5 matching the protective sleeve 1 is provided at the bottom of the main body, and hooks 6 are symmetrically installed on both sides of the lower part of the main body. The cover plate plug 7 is cylindrical, with its height the same as the height of the cover plate settling platform 4, and its inner diameter matching the inner diameter of the cover plate settling platform 4, ensuring that the cover plate plug 7 can be inserted into the cover plate settling platform 4 and fits tightly.

[0019] In actual use, after the pouring operation is completed, the cover plate 3 is placed on the casing 1. The bottom annular groove 5 of the cover plate 3 fits into the casing 1.

The inner diameter of this ring is smaller than the inner diameter of the guide plate 8 and larger than the outer diameter of the guide 13. The outer diameter of this ring is larger than the inner diameter of the guide plate settling platform 9, ensuring that it can stably cover the top of the guide plate settling platform 9. A lifting rope 12 is also installed on the upper part of the guide plate cover plate 10.

[0022] like Figure 8 As shown, a hollow disc 14 is installed at the bottom of the conduit 13. The inner diameter of the hollow disc 14 is the same as the inner diameter of the conduit 13. The outer diameter of the hollow disc 14 is smaller than the inner diameter of the cover plate 3, smaller than the inner diameter of the conduit disc 8, and larger than the inner diameter of the ring formed by the conduit disc cover plate 10 when closed.

[0023] Reference Figures 1 to 8 As shown, the cover plate 3 is normally installed on the casing 1 and connected by the buckle 1 and the hook 6. When the concrete pouring operation of the cast-in-place pile is carried out, the cover plate plug 7 is first taken out from the cover plate settlement platform 4, and then the guide plate 8 is placed in the cover plate settlement platform 4. Then, the guide plate cover plate 10 is opened by the lifting rope 12, and the guide 13 with the hollow disc 14 is inserted into the guide plate 8 and reaches the target position. Then the guide plate cover plate 10 is closed, and the guide 13 is fixed by the guide plate cover plate 10. Then the pouring operation can be carried out. The guide 13 can be adjusted according to the height of the working surface. After the pouring operation is completed, the guide plate 8, the guide 13, etc. are taken out, and the cover plate plug 7 is placed back in place.
