Sandy soil stratum combined pile foundation construction device and method
The invention relates to the technical field of foundation construction, and provides a combined pile foundation construction device and method.The pile foundation construction device comprises an inner pipe and an outer pipe located on the outer side of the inner pipe, a first geotechnical module is arranged on the outer side of the inner pipe, a second geotechnical module is arranged on the inner side of the outer pipe, and the first geotechnical module comprises an impermeable layer; the second geotechnical module comprises a permeable layer, a discrete pile is formed between the first geotechnical module and the second geotechnical module, and a rigid pile is formed in the inner pipe. According to the device, a rigid pile and a discrete pile can be constructed synchronously, period prolonging and cost increasing caused by traditional step-by-step construction are avoided, accurate positioning and tight combination of the rigid pile and the discrete pile in space can be guaranteed, the liquefaction resistance and the pile grabbing quality can be guaranteed, an efficient and stable composite pile foundation structure is formed, and the device has good application prospects and is worthy of popularization and application. The method is particularly suitable for sandy soil foundations, liquefaction sensitive areas and engineering projects with high requirements for the bearing capacity and stability of the foundations.
本发明涉及基础施工技术领域，提供了一种砂土地层的组合桩基施工装置及方法，桩基施工装置包含内管和位于所述内管外侧的外管，所述内管外侧设有第一土工模组，所述外管内侧设有第二土工膜组，所述第一土工模组包含不透水层，所述第二土工模组包含透水层，所述第一土工模组和第二土工膜组之间用于形成散体桩，所述内管内用于形成刚性桩。本装置能够使刚性桩与散体桩同步施工，避免了传统分步施工带来的周期延长与成本增加，还能确保两者在空间上的精确定位与紧密结合，既能保证抗液化性能又能保证抓成桩质量，形成高效、稳定的复合桩基结构，具有较好的应用前景，尤其适用于砂土地基、液化敏感区域以及对地基承载力和稳定性要求较高的工程项目。
