Foundation pit earthwork construction method for civil air defense engineering
The invention relates to a foundation pit earthwork construction method for civil air defense engineering, and belongs to the technical field of civil air defense engineering construction. The foundation pit earthwork construction method for civil air defense engineering comprises the steps that step 1, after surveying and setting out of a deep foundation pit are completed, the deep foundation pit is divided into M
areas from south to north, each area is divided into N construction sections from west to east, and the corresponding mark number of each construction section is defined as M
N
(p is larger than 2, q is larger than 4, and p and q are both positive integers); step 2, before the corresponding construction section is excavated, precipitation pipe well construction is conducted on the construction section; step 3, according to a foundation pit design drawing, excavation is conducted in a partitioned, segmented and layered mode from west to east in a backward sequence; when a (q-1) th foundation pit is excavated, layered excavation is carried out from west to east, excavation sections are M<1>N, M<2>N... M
N sections, excavation sections of a qth foundation pit are M<1>N
, M<2>N
... M
N
sections, layered excavation is carried out from south to north, and riding tracks are arranged at the M<1>N
section; and step 4, according to the mode in step 3, excavation of the foundation pit is completed. The construction efficiency can be improved, and the construction quality is guaranteed.
本发明涉及一种人防工程基坑土方施工方法，属于人防工程施工技术领域。人防工程基坑土方施工方法包括：步骤一：深基坑测量放线完毕后，自南向北将深基坑划分为Mp个区域，自西向东将每个区域划分为Nq个施工段，定义各施工段的对应标号为MpNq（p>2，q>4，并且p、q均为正整数）；步骤二：在对应的施工段进行开挖之前，对该施工段进行降水管井施工；步骤三：根据基坑设计图纸，按照自西向东后退顺序分区分段分层进行开挖；第（q‑1）次基坑开挖时，自西向东分层开挖，开挖工段为M1Nq‑1、M2Nq‑1……MpNq‑1工段，第q次基坑开挖工段为M1Nq、M2Nq……MpNq工段，同时自南向北分层开挖，并在M1Nq工段设置马道；步骤四：按照步骤三的方式，直至基坑开挖完成。能够提高施工效率、保证施工质量。
