Hardening process and hardening device for deep hole grouting outer frame foundation
The invention relates to a deep hole grouting outer frame foundation hardening process and a hardening device, and discloses a hardening process and a hardening device which are used for forming a composite foundation through dot-matrix deep hole grouting pressurization fusion, improving the bearing capacity of the foundation, increasing the adhesion of a foundation soil layer and improving the stability of the soil layer. The method is characterized by specifically comprising the following steps that (1) a grouting point position is selected, and deep hole grouting is conducted through a grouting hardening device; (2) a rammer is used for applying continuous impact pressure to a foundation soil layer near the grouting point, so that soil in the soil layer is fused with concrete grout under the action of the pressure; the method comprises the steps of (1) carrying out foundation construction, (2) carrying out foundation construction, (3) compacting and flattening a whole soil layer of a foundation by using a road roller and further extruding concrete grout to be fused with the soil layer, (4) pouring concrete on the surface of the foundation before final setting of the concrete grout, and (5) flattening the concrete and waiting for solidification of the concrete to form a hard concrete layer.
本发明一种深孔灌浆外架地基硬化工艺及硬化装置公开了一种通过点阵式深孔灌浆加压融合形成复合地基，提高地基承载力同时增加地基土层的黏连性，提高土层稳定性的硬化工艺及硬化装置。其特征在于，具体包括以下步骤：1）选择灌浆点位，利用灌浆硬化装置进行深孔灌浆；2）利用夯土机对灌浆点位附近的地基土层施加连续的冲击强压，使土层土壤在强压作用下和混凝土浆相互融合；3）利用压路机进行地基全土层压实平整，混凝土浆液被进一步挤压和土层融合；4）在混凝土浆液终凝之前，在地基表面浇筑混凝土；5）混凝土平整，等待混凝土固化，形成硬质混凝土层。
