Pile end bottom grouting device, cast-in-place pile and construction method of cast-in-place pile
The invention relates to the technical field of foundations, in particular to a pile end bottom grouting device, a cast-in-place pile and a construction method of the cast-in-place pile. The invention aims at overcoming the defect that in the prior art, the grouting cavity breaking opportunity and conditions are difficult to control. The pile end bottom grouting device comprises a fixing plate, and a grout storage bag fixed to the fixing plate, wherein the grout storage bag forms a containing cavity suitable for containing grout, or the grout storage bag and the fixing plate define the containing cavity suitable for containing the grout, and the grout storage bag has a full state in which the grout is filled to bear a pile body and a closed state inside which the grout is hollow, and a fixed ultimate pressure-bearing strength value is preset in the grout storage bag, and the volume of the grout storage bag is fixed in the full state.
本发明涉及地基基础技术领域，具体涉及一种桩端底部注浆装置、灌注桩及其施工方法，旨在解决现有技术中注浆腔破裂时机和条件控制较难的缺陷。桩端底部注浆装置包括固定板；储浆袋，固定在所述固定板上，所述储浆袋形成适于容置浆液的容置腔或所述储浆袋与所述固定板围成适于容置浆液的容置腔，所述储浆袋具有内部填充浆液以承载桩体的充盈状态和内部中空的收拢状态，所述储浆袋预设固定的极限承压强度值且在充盈状态下容积固定。
