Abstract
Lankao from Lianhuo highway expansion project to the Liu Jiang Section 17 million mark in highway overpass separate pile-point start instance, analyzes the pile construction should be noted, as well as supervision of the construction process and quality elements that should be Note that the issues in order to ensure the quality and progress.
Geology in the sand with a bridge, the use of bored piles, the design pile length is 22 meters, with four piers, and a pier four, the foundation construction is difficult, the quality factors of instability and more demanding. Control the pile foundation should focus on positioning, and socketed into the rock to determine the depth, sediment thickness, concrete placing, construction of pile top elevation, and other links.
Keywords: pile foundation; construction and supervision
From connect Huo superhighway the orchid test into Liu Jiang Duan to change to extend engineering the number 17 marks ten thousand high way hole tax disconnect the stake cardinal points type in type interchange start work a solid instance to set out, analysis stake the radicle is under construction to note of question, and superintendency vs construction the process flow and mass main should note of question to ensure the mass and progress of engineering.
The bridge is placed in sandy soil geology tape, the adoption drilling infuses to note a stake, design stake lengthways for 22 meters, there are four Dun stands, and be four for one Dun, starting construction because of this radicle the difficulty is big, mass unsteady factor poly -, have high request.Should particularly control a good stake radicle clamping, go into a rock judgement and Qian rock depth, sink dirt thickness and Mao to infuse to note, stake the vertex elevation each construction of etc. link.
Keyword: Stake foundation;Start construction with Jian
