厦门嵩屿电厂煤码头大管桩内嵌岩锚杆施工工艺

Rock-Embedding Drilling Technology of Large-Sized Pipe Piles Applied to the Construction of a Coal Wharf of the Xiamen Songyu Electric Power Station

在大管桩内定位施工嵌岩锚杆，是我省首次用来加固码头栈桥的一种可行办法。在下定位装置及锚杆施工工艺过程中，对锚杆进行抗拔试验，其抗拔力达到设计要求，说明本次施工工艺是成功的，为提高码头桥墩的抗技力，又开辟了一条新路，这无疑是很有现实意义的。

In the construction of a coal wharf of the Xiamen Songyu Electric Power Station, some rock-embedding anchor-shaped rods have been used in the construction of large-sized pipe piles by the in-location method, which is first applied to strengthen a landing stage in the wharf construction of Fujian Province. An anti-drawing test of the rock-embedding anchorshaped rods was undertaken during the construction, which showed that the anti-drawing of the rock-embedding anchor-shaped rods came up to the designing standards and the drilling technology was practical. The internal rock-embedding drilling technology can be widely used to strengthen the anti-drawing of bridge piers or an underwater foundation.
