Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation engineering devices, in particular to a pile foundation anti-sinking device. Background Art

[0002] Pile foundation is an ancient foundation type, and pile construction technology has gone through thousands of years of development. Whether it is pile foundation materials and pile types, or pile construction machinery and construction methods, there have been great developments, and a modern foundation engineering system has been formed. In some cases, the use of pile foundations can greatly reduce the workload and material consumption on the construction site, but the pile foundation is prone to negative friction under the construction loading of the upper part of the upper pile foundation, and the deformation of the soil in contact with it makes the pile foundation prone to certain settlement. Generally speaking, a pile foundation is a deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation. The pile body is exposed above the ground and the bottom of the cap is above the ground. It is called a high cap pile foundation. Ground buildings, such as high-rise buildings, bridges, etc., often use pile foundations as supporting foundations. The bearing capacity of the pile foundation usually consists of two parts, one is the side friction resistance generated by the contact between the soil and the side of the pile foundation, and the other is the pile end resistance generated by the contact between the bottom of the pile foundation and the soil. Due to the different soil properties in different regions, some highly compressible soft soils such as backfill soil, site silt, etc. have high water content and are characterized by rheological and uneven properties. Under the action of upper construction loading, the pile foundation produces negative friction, and the soil in contact with it deforms, causing the pile foundation to settle to a certain extent. Based on the above problems, this device is specially proposed.

[0003] A new type of high-efficiency pile foundation anti-sinking device disclosed in the publication number CN215165772U, although the connection length of the support rod and the connecting rod is adjusted by a length adjustment device, at the same time, an angle adjustment device is provided to make the support rod and the connecting rod always located on the same straight line, thereby realizing adjustable installation of the support seat relative to the support seat, which has the effect of wider applicability.
