Abstract

The invention provides a comprehensive pile sinking method for penetrating through a geological hard layer. The comprehensive pile sinking method for penetrating through the geological hard layer comprises the following steps: excavating and removing the geological hard layer near a pile station; backfilling soil and compacting the excavated and removed area; punching a pile position pre-embeddedarea to form a guiding hole; arranging a pile tip at a pre-embedded end of a pile, and arranging steel fibres at the end, far away from the pre-embedded end, of the pile; and driving the pre-embeddedend of the pile into the guiding hole. Compared with the prior art, the comprehensive pile sinking method for penetrating through the geological hard layer has the beneficial effects that the pile canbe driven into the geological hard layer easily by excavating and removing the geological hard layer on a surface in advance and pre-drilling the hole by the comprehensive pile sinking method for penetrating through the geological hard layer provided by the invention, so that repeated beating when the pile penetrates through the geological hard layer is avoided; a large amount of time is saved; and the labour intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of pile foundation engineering in the metallurgical industry, in particular to a PHC comprehensive pile sinking method for penetrating the geological hard layer on the surface of an old material yard. Background technique [0002] At present, the raw material yard of iron and steel enterprises is one of the main sources of pollution in the metallurgical industry. With the upgrading of user capacity, the amount of raw materials is also increasing. Newly build or renovate environment-friendly raw material yards. The old stockyards generally have been treated with sand pile foundations, and through long-term mineral stockpiling, the shallow layer of about 10m has been hardened and consolidated. In addition, the construction of PHC piles in the newly built environmental protection stockyards is large in volume, high in density, and short in construction period. At present, the conventional PHC pile sinking oper...
