Construction method for uplift pile serving as floor support and stand column support replacement
The invention relates to the technical field of parking lot construction, in particular to a construction method for using an uplift pile as a floor support and a stand column support replacement, which comprises the following steps: excavation of a foundation pit, construction of a three-shaft mixing pile and construction of a guide wall. Uplift pile construction: constructing a stand column pile on the uplift pile; laying a cover plate, and pouring laminates layer by layer from top to bottom; after the bottommost layer plate is poured, pouring a cast-in-place pile in the soil layer below the bottom layer, meanwhile, constructing a supporting pile on the cast-in-place pile, connecting the supporting pile with each layer plate in sequence, and connecting the top of the supporting pile with the topmost layer support; and cutting and removing the stand column pile, and cutting off the part of the uplift pile higher than the lowest layer plate. Construction is conducted in a cover and excavation top-down mode, the overall construction efficiency is improved, the upright pile is constructed on the uplift pile, confrontation with buoyancy borne by the uplift pile and the lowest layer of the laminate is facilitated, temporary supporting of the cover plate and the laminate is achieved while anti-floating is achieved, the uplift pile is used for supporting the upright pile, and the uplift pile is used for supporting the cover plate and the laminate. And materials required to be supported by the upright post pile and the construction cost are saved.
本发明涉及停车场施工技术领域，尤其涉及一种抗拔桩兼做楼板支撑和立柱换撑的施工方法，包括如下步骤：基坑开挖，三轴搅拌桩施工，导墙施工；抗拔桩施工，抗拔桩上施工立柱桩；铺设盖板，自上而下逐层浇注层板；最底层层板浇注完毕后，在底层下方土层内浇注灌注桩，同时在灌注桩上施工支撑桩，支撑桩依次与每层层板连接，支撑桩的顶部与最上层支撑连接；将立柱桩切割拆除，将抗拔桩高于最下层层板部分切除。通过盖挖逆作的方式施工，提升整体的施工效率，通过在抗拔桩上施工立柱桩，便于与抗拔桩及最下层层板受到的浮力对抗，在实现抗浮的同时，实现对盖板和层板的临时支撑，另利用抗拔桩做立柱桩的支撑，节省了立柱桩所需支撑的材料和施工成本。
