Manual hole digging pile pre-mixed material concrete retaining wall construction method
The invention relates to the field of tunnel and underground engineering construction, in particular to a manual hole digging pile pre-mixed material concrete retaining wall construction method. The construction method includes the steps that S10, pile holes are dug; S20, steel bar bundling and formwork closing are conducted; S30, water is added into a pre-mixed concrete dry material for mixing sothat pre-mixed material concrete can be formed; and S40, concrete pouring is performed, single retaining wall sections are formed, then digging and pouring are conducted again to form the next retaining wall section, and a pre-mixed material concrete retaining wall containing multiple retaining wall sections is formed after construction of the multiple retaining wall sections is completed. Concrete added with an accelerator has the characteristics of early strength, stable strength and the like, the pre-mixed concrete dry material manufactured in advance is added with the water to be mixed directly during construction so that the pre-mixed material concrete can be formed for pouring, construction time and strength waiting intervals are greatly shortened, field retaining wall constructioncontinuity is effectively guaranteed, and the problems that the construction technology interval time between the upper retaining wall sections and the lower retaining wall sections is long, construction time is also long and the hole-forming construction speed is low are solved.
本发明涉及隧道及地下工程施工领域，特别涉及一种人工挖孔桩预拌料混凝土护壁施工方法，该施工方法包括步骤S10进行桩孔开挖，步骤S20进行钢筋绑扎和模板关模，步骤S30将预拌料混凝土干料加入水进行搅拌形成预拌料混凝土，步骤S40进行混凝土浇筑，形成单节护壁，然后再次开挖并浇筑形成下一节护壁，多节护壁施工完成后形成包括多节护壁的预拌料混凝土护壁。加入了速凝剂的混凝土具有早强、强度稳定等特点，预先制成的预拌料混凝土干料在施工时直接加水搅拌形成预拌料混凝土进行浇筑，大大缩短施工时间和强度等待间隔，有效保证了现场护壁施工的连续性，解决了上下节护壁之间施工技术间隔时间较长、施工时间长、成孔施工速度慢的问题。
