陈庄镇中学2012年冬季安全工作实施方案 为切实做好我冬季校园安全工作，促进全校安全形势持续稳定，结合实际，从现在起到201年3月底，开展“冬季安全行动”，特制定方案。 陈庄镇中学 2012年12月20日 deformation small; Dang engineering pile also for perfusion pile Shi, can synchronization construction, to construction conducive to organization, and convenient, and duration short; pile between gap easy caused soil erosion, special Shi in high level soft clay quality area, needed according to engineering conditions take note pulp, and cement mixing pile, and spin spray pile, construction measures to solution block water problem; Suitable for soft clayey and sandy areas, but construction should be used with caution in the gravel and pebbles; between pile and pile through the pile top beam and wall purlins into overall and thus relatively poor overall, as in important areas, special projects and large Foundation pit in excavation depth application requires special care. 2.1.6 steel piles using steel piles supporting the Foundation pit for temporary support features, construction convenient, short, finished construction in Foundation pit backfill after the channel pulled out, re-use, can minimize the cost of support. Used steel piles supporting a fatal weakness, that is impervious to water and small soil particles, and also called as high water precipitation or water, and the underground water level is high, water-rich geological conditions did not match. Flexural capacity of steel sheet pile supporting weaker excavation depth does not exceed 4m deflection of more general application. Obviously the soft water of Foundation pit excavation depth of geological conditions of 10m, and is located in the city centres of Flex ... Limited to, work hard, and it can take full advantage of building line the walls within a limited number of ground and space, can give full play to its economic benefits, in the course of construction,2 deformation small; Dang engineering pile also for perfusion pile Shi, can synchronization construction, to construction conducive to organ
