Steel-concrete underground engineering building construction method
The invention discloses a steel-concrete underground engineering construction method, which belongs to the technical field of constructional engineering, and comprises the following steps of: arranging a construction site to flatten the surface of the site, and then finishing the moving work of pipelines; then dewatering and unwatering are conducted on the foundation pit, then the pit bottom is subjected to preliminary reinforcement, and then a local waterproof curtain is laid for the first time; the first channel foundation pit is excavated, and pit body reinforcing work is conducted after the first channel foundation pit is excavated to a proper depth; a plain concrete cushion layer is poured, a structure is built back after pouring is completed, foundation pit cooling is conducted after building back is completed, soil is filled back after the solidified structure reaches the standard, and a temporary road is laid on a top plate; and the second-stage second foundation pit and the third-stage third foundation pit are constructed in the same mode, and then the waterproof curtain is laid for the second time. Cold field ice blocks are input into the refrigerator car, cold air in the refrigerator car is conveyed to the air supply pipeline through the draught fan, the air supply pipeline cools the back-building structure, and therefore the cooling efficiency is improved.
本发明公开了一种钢混地下工程建造施工方法，属于建筑工程技术领域，包括以下步骤：对施工场地进行整理，使其场地表面平整，随后完成管线的搬迁工作；接着对基坑进行降水和疏干，然后对坑底进行初步加固，接着进行局部止水帷幕的初次铺设；对第一通道基坑进行挖掘，当挖掘到合适深度后进行坑体加固工作；浇筑素砼垫层，浇筑完成后回筑结构，回筑完成后进行基坑冷却，待凝固结构达标后回填土体，并在顶板上铺设临时道路；采用同样的方式施工二期第二基坑和三期第三基坑，然后进行二次铺设止水帷幕。本发明通过向冷藏车内部输入冷场冰块，再利用风机将冷藏车内部的冷气输送给送风管道，由送风管道对回筑结构进行冷却，从而加快冷却效率。
