Bored Pile

A viaduct of the Qinglai expressway fourth contract was artificial excavated piles. The construction technical work was regarded as an example. The technical comparison were done between the artificial excavated pile and the bored pile on the pile foundation bearing capacity and the retaining wall effect . The artificial excavated pile replacing the bored pile was feasible, and the construction technology and the key problems of the artificial excavated piles were confirmed. The references were provided to the similar projects.

Currently, bored pile been widely applied in the current road and bridge construction, But its construction technology in complex geological case is still not perfect. In view of this, this paper carried out a high-speed Lakes viaduct extraordinary pile foundation construction project. For the analysis of the technical difficulties in the construction process, explore get the corresponding key construction technology, and it relates to the accident and its approach are summarized, study drew long pile construction technology Lakes geological conditions under soft silt and clay, solve the long holes bored pile into the lake silt soft clay under geological conditions, verticality control and other technical problems, can provide reference for similar projects.

Aiming at reducing the influence caused by the pile foundation construction on the existing structures nearby, this paper introduces a new technology of spinning casing bored pile, which is the optimization and combination of different construction technologies. Through the corresponding calculation and analysis, the influence scope and extent of this technology is obtained in this paper. This technology has been successfully applied in the pile foundation engineering of a passenger dedicated line close to subway shield tunnels, it can provide the similar project that needs to consider the influence on the surroundings with reference, and it is worth wide promotion and application.

Bored Piles

Filling pile is a common form of pile foundation work, it passes the superstructure loads to the deep stabilitily soil or rock , reducing the non-uniform settlement of ground and foundation. Because of bored piles is done underground, underwater, quality control is difficult. The construction technology and quality control measures of bored pile is been introduced.
