Prefabricated root type pile structure and construction method
The invention belongs to the technical field of engineering construction, and particularly relates to a prefabricated root type pile structure. The prefabricated root type pile structure is a prefabricated root type pile formed by pushing root keys on the side wall on the basis of a prefabricated pipe pile. The prefabricated root type pile structure comprises the pipe pile, a pushing and extendingroot key box and an inner core grouting body, wherein the pushing and extending root key box is embedded in the side wall of the pipe pile, made of steel and composed of a reinforcing steel sleeve, the foundation root keys and the pushing root keys, the pushing and extending root key box is fixed to the wall of the pipe pile according to a certain rule, and the self-locking function is achieved.After the pipe pile is constructed to the bottom of the pile, the pushing and extending root keys are ejected out through pushing equipment, grouting is conducted on the pipe pile and inner cavities of the root keys, the bearing characteristic of the root keys is brought into play, the pile bearing capacity is improved, and the bionic prefabricated pile similar to a tree root is formed. The bond stress of the root keys increases the stability and bearing capacity of a foundation, the structural dead weight is reduced, and good economical efficiency is achieved. The prefabricated root type pilestructure has the beneficial effects of being simple in structure, safe, firm, capable of shortening the construction period and saving the manufacturing cost and the like.
本发明属于工程施工技术领域，具体涉及一种预制根式桩结构，一种预制根式桩结构是指在预制管桩的基础上，通过侧壁顶推根键而形成的一种预制根式桩，包括管桩，推伸根键盒和内芯注浆体；管桩侧壁嵌有推伸根键盒，材质为钢材，由加强钢套、基础根键和顶推根键组成，呈一定规则固定管桩壁上，且具有自锁功能。管桩施工至桩底后通过顶推设备将伸推根键顶出，并对管桩和根键内腔注浆，发挥根键承载特性提高桩承载力形成类似树根的仿生预制桩。根键的握裹力，增大基础的稳定性和承载力，减轻结构自重，具有良好的经济性，具有结构简单、安全牢靠、节省工期、节省造价等优点。
