Description

Technical Field

[0001] The invention relates to the technical field of pile foundation construction, and in particular to an embedded part supporting and protecting device. Background Art

[0002] In engineering construction, bored cast-in-place piles are a commonly used type of piles. A pile hole is formed by mechanically drilling a hole in the foundation, and a steel cage is placed in the pile hole and then concrete is poured into the hole. During construction, embedded parts such as casing are usually used for auxiliary work to fix the pile position, guide the drilling direction, isolate surface water, stabilize the hole wall, prevent the hole from collapsing, and protect the original ground at the hole mouth. However, in the actual work process, firstly, due to geological differences or mechanical vibrations, embedded parts are easy to sink, resulting in the inability to ensure the depth of pile formation, affecting the quality of pile formation, and when the embedded parts sink seriously, they are easy to fall into the pile hole, making it difficult to salvage, seriously affecting the progress of the project and the quality of pile formation. Then, the steel cage and the conduit cannot be positioned when they are placed. When pouring concrete into the pile hole, the steel cage and the conduit are easy to deviate, resulting in poor hole formation quality or even low hole formation rate, which requires repair or re-drilling, affecting the construction progress. In addition, mud is easy to overflow from the top of the pile hole, and workers usually step directly in the mud, resulting in a messy site, a poor construction environment, and low safety. In addition, due to the lack of protective measures, it is easy for debris to fall into the pouring hole, affecting the quality of the pile hole. Therefore, a device for supporting and protecting the embedded parts is required at the construction site.

[0003] At present, there are separate positioning casings and steel cage hoisting and positioning devices in the prior art, such as patent number 2020210243458, named anti-slip positioning steel casing for mechanically bored cast-in-place piles, which adopts annular flange plates to evenly disperse the complex loads at the hole mouth of the bored pile, effectively protect the ground at the hole mouth, and reduce or avoid the loss of construction period and economic losses caused by the slipping of the positioning steel casing. This patent cannot guarantee the accuracy of the pile depth, resulting in the pile hole quality not meeting the requirements, and the ground around the pile hole is muddy, the environment is poor after the construction workers step on it, and it cannot meet the environmental protection requirements; another example is patent number "202322622114.7" and named "A pile steel cage hoisting and positioning device", which arranges multiple An elastic positioning column, on the one hand, is used to position the pile reinforcement cage. On the other hand, during the lowering process of the pile reinforcement cage, when the pile reinforcement cage deviates and squeezes the elastic positioning column in the radial direction of the pile hole, the elastic positioning column can be appropriately compressed to play an elastic role, protect the pile reinforcement cage, and avoid damaging the pile body reinforcement cage protective layer. However, the elastic part of the elastic positioning column adopts a spring or a rubber pad or an elastic support. When a spring is used, the state of each spring is inconsistent due to different forces. After long-term use, the spring with more force is prone to failure, and its elastic effect cannot be played when placing the reinforcement cage, causing the reinforcement cage to be offset; and when a rubber pad or an elastic support is used, it is easy to wear or deform, and it cannot avoid the offset when placing the reinforcement cage. Therefore, the two structures mentioned above need to be positioned separately, which is prone to inaccurate positioning, and it is impossible to avoid the offset when placing the reinforcement cage and the conduit, which affects the construction progress and pile hole quality. Summary of the invention
