Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a protective device for bored piles. Background Technology

[0002] In existing technologies, on-site construction of manually excavated bored piles faces challenges due to limited working space within the shaft, cumbersome installation and dismantling procedures during the construction of traditional protective sheds, difficulty in transporting larger components to the installation location, high labor costs, and low reuse rates. Furthermore, the stability of on-site assembled structures is insufficient due to variations in worker techniques, making it difficult to ensure construction safety in the face of external impacts. These issues include limitations imposed by working space, difficulties in transporting components, low reuse rates, and susceptibility to structural instability influenced by differences in installer techniques.

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the utility model, and not all embodiments.

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout.

[0021] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that terms such as "installation", "connection", and "fixing" should be interpreted broadly, and can refer to direct connection, installation or fixing, or indirect connection, installation or fixing, and the present invention does not impose any limitation in this regard.

[0022] like Figures 1 to 4As shown in the schematic diagram of an embodiment of the protective device for bored piles of this utility model, it includes multiple fan-shaped protective units. The multiple fan-shaped protective units can be arranged sequentially along the circumference to form a protective canopy for shielding. Adjacent fan-shaped protective units are rotatably connected to fold or unfold. The protective wall covering the inner wall of the bored pile is adapted to the arc curvature of the fan-shaped protective units. The protective wall and the fan-shaped protective units are detachably connected.

[0023] In this embodiment, the protective wall is formed by axially splicing multiple annular protective wall units 5. Each annular protective wall unit 5 has a stepped structure at its top, and adjacent annular protective wall units 5 interlock through the stepped structure to form an annular protrusion 51 on which a fan-shaped protective unit can be erected. Preferably, the inner diameter of each annular protective wall unit 5 gradually increases from top to bottom, forming a gradually expanding structure.

[0024] In this embodiment, the radius of the fan-shaped protective unit is larger than the radius of the circle formed by the circumferential boss 51 to form a non-enclosed umbrella-shaped protective canopy with a slight arch in the middle. The protective canopy formed by multiple fan-shaped protective units can form an interference fit with the retaining wall. That is, when the protective canopy is installed in the bored pile, the height of the protective canopy at the center of the bored pile is higher than the height of the outer edge of the arc of the protective canopy, which better ensures the structural stability of the protective canopy when it is impacted by falling construction debris, avoids the protective canopy from falling off accidentally, and ensures construction safety.

[0025] In this embodiment, there are two sector-shaped protective units, each of which is a 1 / 4 circle structure.

[0026] In this embodiment, each sector-shaped protective unit includes a support frame and a protective surface 4 connected to the support frame, with adjacent support frames rotatably connected. Preferably, the support frame includes an annular base 3 and multiple connecting rods 1, the length of each connecting rod 1 being equal to the radius of the sector-shaped protective unit. The multiple connecting rods 1 intersect at the center of the circle, and each connecting rod 1 is connected to the annular base 3 for reinforcement. The annular base 3 and each connecting rod 1 are connected to the protective surface 4. Adjacent sector-shaped protective units are connected by connecting rods 1. The protective surface 4 can be made of a buffer plate to block falling construction debris and reduce the risk of injury to personnel. The support frame can be made of high-strength stainless steel, and the protective surface 4 can be one or more combinations of protective netting, metal plates, or wooden boards.

[0027] In this embodiment, each sector-shaped protective unit is provided with a connecting component 6 on its side. The connecting component 6 includes a first connecting member 61 connected to the corresponding support frame and a second connecting member 62 rotatably connected to the first connecting member 61. Adjacent sector-shaped protective units are connected through the second connecting member 62. Preferably, each second connecting member 62 is provided with a socket for connection. The interconnected second connecting members 62 can be fixed by corresponding sockets and by inserting a fixing member 2, which can be a fixing pin.

[0028] The construction steps of this utility model are as follows:

[0029] Install the annular retaining wall unit 5 segment by segment to ensure that the adjacent units are tightly spliced ​​together and form an annular protrusion 51;

[0030] Multiple fan-shaped protective units are connected to form a protective shed. The protective shed is folded and transported manually or by hoisting equipment into the bored pile, reaching the target circumferential retaining wall unit 5.

[0031] Unfold the protective canopy so that the outer arc surface of the fan-shaped protective unit abuts against the protective wall and achieves an interference fit. At this time, the annular base 3 is erected on the circumferential protrusion 51, forming a non-enclosed umbrella-shaped protective structure with a slight arch in the middle. The area not covered by the protective canopy can form a transportation channel.

[0032] When the protective canopy needs to be dismantled, the fixing piece 2 at the top center can be pushed back to fold the protective canopy to reduce the space occupied, making it easier to transport, store and reuse.

[0033] This embodiment utilizes the retaining wall structure to construct the protective shed, forming an interference fit with the retaining wall. Geometric constraints not only reduce installation operations such as bolting and improve construction efficiency, but also simplify operation and reduce differences in installation techniques among personnel. The non-enclosed umbrella-shaped protective shed, through its arched design, can resist and buffer the impact of falling construction debris. The interference fit between the protective shed and the retaining wall not only gives the protective shed excellent load-bearing capacity, but also prevents it from accidentally falling due to the impact of falling objects, ensuring the stability of the bored pile protective device and the temporary protective effect, and facilitating installation and dismantling.

[0034] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
