Plain concrete pile static test anchor pile counter-force technology based on post-embedded steel bars
The invention provides a plain concrete pile static test anchor pile counter-force technology based on post-embedded steel bars. The technology comprises the steps of calculation, distribution, comprehensive success rate calculation, implementation and completion of a static test, wherein the calculation comprises the steps that according to the design bearing capacity and pile foundation distribution condition of a plain concrete pile, the specification and depth of the steel bars embedded into a pile body and the number of pile groups participating in the counter-force effect are calculatedand determined so as to meet the enough counter force required by the static test; and the distribution comprises the steps that the number of the pile groups participating in the counter-force effectis an even number as much as possible, the pile groups are symmetrically distributed, and one or more steel bars can be embedded into each pile. According to the technology, although only one or a small number of steel bars are embedded into an anchor pile, on the basis of scientific calculation, a large number of field test researches show that the static test does not cause any damage to concrete of the pile body of the anchor pile, and no tension crack occurs. The pile body is complete and does not bear the too large tension load of the post-embedded steel bars and the static test. The field pile group resources are fully mobilized, and the post-embedded steel bar mode is flexible.
本发明提供一种基于后植筋的素混凝土桩静载试验锚桩反力技术，包括计算、分布、综合成功率计算、实施、完成静载试验；所述计算包括根据素混凝土桩的设计承载力和桩基分布情况，计算和确定植入桩身钢筋的规格、深度以及参与反力作用的群桩数量，以满足静载试验所需的足够反力；所述分布步骤包括：参与反力作用的群桩数量尽量为偶数且对称分布；每根桩可以植入一根或多根钢筋；本发明虽然在锚桩中仅仅植入一根或少量的钢筋，但在科学计算的基础上，经过大量现场试验研究表明，静载试验未对锚桩桩身混凝土造成任何破坏，未出现任何受拉裂缝。其桩身完整，没有承受后植筋和静载试验过大的受拉荷载。充分调动了现场群桩资源且后植筋方式机动灵活。
