Abstract

The invention discloses a cast-in-place pile applicable to a karst region having communicating channels. The cast-in-place is applicable to the karst region having the communicating channels, and comprises a pile body that is arranged in the karst region having the communicating channels, and a covering part that covers a steel reinforcement cage of the pile body before pile forming; a diameter of the covering part is greater than a diameter of the steel reinforcement cage of the pile body before pile forming, and a length of the covering part is greater than a height of the steel reinforcement cage of the pile body before pile forming; in a use state, the covering part extends into the communicating channels in the karst region, and the covering part extending into the communicating channels is filled with concrete slurry. The cast-in-place pile of the present invention is capable of better combining with integral rock in the communicating karst region for bearing together, and also capable of remarkably increasing the pile side frictional resistance of a pile foundation, thereby improving the integral bearing capability of the foundation.

Description

technical field

[0001] The invention relates to the construction field, in particular to a cast-in-situ pile suitable for karst areas with interconnecting passages. Background technique

[0002] Karst is the general term for the geological action of water on soluble rocks such as carbonate rocks, gypsum, rock salt, etc., which is mainly chemically dissolved, supplemented by mechanical actions such as water erosion, submerged erosion, and collapse, and the phenomena caused by these actions. . The karst areas in my country are mainly concentrated in the southwest region, which accounts for more than one-third of the entire southwest area, and the geological conditions of the karst areas are extremely complex. When carrying out infrastructure design and construction in karst areas, the design requirements are high, the construction is difficult, the cycle is long, construction accidents are prone to occur, and the design and construction costs are greatly increased. In the mi...
