Description

Technical Field

[0001] The utility model relates to the technical field of pile foundations, in particular to a pile foundation which is convenient for drainage. Background Art

[0002] During the construction of pile foundation, the pile body needs to be driven into the foundation. If the construction area is a region with high water content and poor water permeability, it is easy to cause excess pore water pressure after the pile body is driven into the foundation. This excess pore water pressure can easily reduce the friction resistance of the side wall of the pile body and affect the bearing strength of the pile body.

[0003] In order to solve the above technical problems in the prior art, a number of drainage holes are opened on the side wall of the pile body. The water in the soil enters the interior of the pile body through the drainage holes, and then the water inside the pile body is pumped out by a pump body, thereby reducing the moisture content of the soil around the pile body, thereby reducing the pore water pressure in the soil and improving the bearing capacity of the pile body.

[0004] However, the applicant found that when moisture in the soil enters through the drainage holes, part of the soil will follow in, and under natural conditions, the efficiency of moisture automatically entering the pile body is low. In this way, it takes a long time to pump out the water in the pile body, which affects the drainage speed. For this reason, we propose a pile foundation that is easy to drain. Utility Model Content
