Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rock-embedded pile construction devices, in particular to a construction device that utilizes sediment to improve the bearing capacity of rock-embedded piles. Background Art
[0002] Rock-embedded piles refer to bored piles with a considerable length of the lower part of the pile cast in hard rock. Regardless of the degree of weathering of the rock mass, as long as the pile end is embedded in the rock mass, it can be called a rock-embedded pile. The differences in the characteristics of rock-embedded piles embedded in rock masses with different characteristics are caused by the differences in rock mass characteristics, and sediment is the debris produced by drilling.
[0003] While bearing vertical loads, rock-embedded piles may also be subject to lateral loads or eccentric loads, such as earthquake and wind loads. When the lateral load is large, a larger pile diameter must be used to increase the horizontal stiffness of the structure to reduce the overall horizontal displacement of the structure. However, increasing the pile diameter will increase the construction cost. Therefore, using sediment to increase the bearing capacity of rock-embedded piles is a more cost-effective way.
