检查数量:每1000?、每压实层抽检3个点。

检验方法:环刀法、灌水法或灌砂法
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,
