Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation pouring enclosure, in particular to a pile foundation pouring enclosure device. Background Art

[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile (referred to as the cap) or a single pile foundation connected by a column and a pile foundation is referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations. In high-rise buildings, pile foundations are widely used. When pouring low cap pile foundations, it is necessary to set up enclosures in advance as a preventive fixation for construction.

[0003] Traditional pile foundation casting enclosure devices are usually cylindrical tubes. After the pile foundation is cast, two methods are used: removal or retention. If it is removed, the formed pile foundation will lose its auxiliary support and protection effect. If it is retained, the cost is high. Therefore, it is impossible to achieve protection while reducing costs. In view of this, we propose a pile foundation casting enclosure device. Utility Model Content
