[0002] With the development of the global economy and the acceleration of urbanization, various large-scale construction projects, bridge projects, port projects, and other projects are constantly emerging. These projects place increasingly higher demands on the bearing capacity and stability of the foundations, and traditional foundation types are unable to meet these needs. Drilled piles, with their advantages of adapting to various complex geological conditions and allowing for adjustments in pile length and diameter to provide greater bearing capacity according to project requirements, have gradually become a commonly used foundation type in the engineering field.

[0003] During the concrete pouring process of cast-in-place piles, the concrete pouring pipe needs to be kept in the center of the pile hole to ensure the uniformity of the concrete. Traditionally, the pouring pipe of bored cast-in-place piles is fixed by clamping it with a wire rope, but it is easy to move and deviate during the lowering and lifting process. Therefore, this utility model provides a device suitable for fixing the concrete pouring pipe of bored cast-in-place piles. Utility Model Content

[0037] Please refer to the attached document. Figures 1-4 This application illustrates a device for fixing concrete pouring pipes for bored piles, which is used to position and fix the concrete pouring pipes during the concrete pouring process of bored piles. Specifically, it includes: a cross-shaped support 2, a limiting baffle 4, and a clamp 9.

[0038] The cross-shaped support component 2 is cross-shaped to facilitate its placement at the top of the pile hole. A rectangular opening 3 is located at the center of the cross-shaped support component 2, and a limiting baffle 4 is installed thereto guide and position the concrete pouring pipe downwards from this point, ensuring that the concrete pouring pipe is located at the center of the pile hole. Specifically, the limiting baffle 4 is hinged to the top of the cross-shaped support component 2, and the limiting baffle 4 corresponds to the rectangular opening 3. Two sets of limiting baffles 4 are symmetrically arranged, and semi-circular openings 5 ​​are opened on the sides of the limiting baffles 4. The semi-circular openings 5 ​​of the two sets of limiting baffles 4 form a circular guide opening. The diameter of the circular guide opening is slightly larger than the outer diameter of the concrete pouring pipe, allowing the concrete pouring pipe to extend downwards from this point.

[0039] The clamp 9 is installed on the outside of the concrete pouring pipe, and the inner diameter of the circular guide opening is larger than the outer diameter of the concrete pouring pipe, and the outer diameter of the clamp 9 is larger than the inner diameter of the circular guide opening.

[0040] When in use, place the integrated cross-shaped support 2 and the limiting baffle 4 at the top of the pile hole, adjust the circular guide port to correspond with the center of the pile hole, and then extend the concrete pouring pipe downward from the circular guide port. This ensures that the concrete pouring pipe is located in the center of the pile hole. When the concrete pouring pipe is about to extend to the predetermined depth, install the clamp 9 on the outside of the concrete pouring pipe. When the concrete pouring pipe extends to the predetermined depth, the clamp 9 is locked on the top of the cross-shaped support 2 to limit the drooping of the concrete pouring pipe and ensure the stability of the concrete pouring pipe when pouring concrete.

[0041] In one embodiment, the cross-shaped support member 2 includes: a main steel frame 201, a side steel frame 202, and a plurality of connecting members 203.

[0042] Two sets of main steel frames 201 are arranged in parallel and spaced apart, and several connectors 203 are fixedly connected between the two sets of main steel frames 201, so that the two connectors 203 near the center and the two sets of main steel frames 201 form a rectangular opening 3. One end of the side steel frame 202 is fixedly connected to the outside of the main steel frame 201, and the side steel frame 202 and the main steel frame 201 are distributed in a "T" shape.

[0043] like Figure 3 The cross-shaped support component 2 shown is structurally stable and uses less material; generally, the main steel frame 201, the side steel frame 202, and several connecting components 203 are made of channel steel / I-beams.

[0044] In one embodiment, in order to facilitate the use of hoisting equipment to maneuver the cross-shaped support 2 into position, lifting rings 6 are fixedly connected to the top of the two connectors 203 near both ends of the main steel frame 201. The lifting rings 6 are used to connect the wire rope of the hoisting equipment.

[0045] In one embodiment, to ensure the safety of construction, a platform cover plate 7 is also designed. The platform cover plate 7 is set on the top of the cross-shaped support member 2. The platform cover plate 7 and the cross-shaped support member 2 can be combined by fixing or positioning, so that the platform cover plate 7 has a square hole 8 corresponding to the rectangular opening 3. The platform cover plate 7 can be used for construction personnel to stand on, and does not affect the positioning and fixing of the concrete pouring pipe.

[0046] In one embodiment, when a casing 1 is installed inside the pile hole, a number of guide members 10 arranged in a ring can be fixedly connected to the bottom of the cross-shaped bracket 2, and the outer side of the guide member 10 is set as an inclined side.

[0047] The design of the guide component 10 allows the cross-shaped support component 2 to be positioned at the center of the pile hole more quickly, which is especially convenient when hoisting.

[0048] The cross-shaped support component 2 may affect the inside of the pile hole and cause local collapse. It is generally used in the scenario where the casing 1 is installed inside the pile hole.

[0049] In one embodiment, the clamp 9 includes two sets of symmetrically arranged first semicircular parts 901 and a connecting shaft.

[0050] The two sets of first semicircular parts 901 are fixed in a ring shape on both sides by connecting shafts; specifically, the connecting shaft includes: shaft member 902, the first end of shaft member 902 is threaded with a mounting nut 903, the second end of shaft member 902 is flat and a rotating seat is rotatably mounted on the second end of shaft member 902, a cam member 905 is fixedly connected to the inner side of the rotating seat, and a handle member 904 is connected between the two rotating seats corresponding to the two connecting shafts.

[0051] When in use, rotate the handle 904 downwards. At this time, the protruding part of the cam 905 is away from the first semicircular part 901. The user installs the mounting nut 903 and keeps the two sets of first semicircular parts 901 loose. At this time, the concrete pouring pipe can slide between the two sets of first semicircular parts 901. When it needs to be fixed, simply operate the handle 904 to slide it upwards, which drives the cam 905 to rotate. The protruding part of the cam 905 abuts against the first semicircular part 901, so that the two sets of first semicircular parts 901 tightly hold and fix the concrete pouring pipe.

[0052] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of the present invention are indicated by the following claims.
