By combining with the work experiences,the paper emphasizes on the introduction of the common quality problems of the beating or pressing and grouting concrete piles construction,analyzes the reasons,and sums up some regular treatment methods and the technological measures,so as to avoid or reduce similar quality problems,and to ensure the safety of the buildings.

The supervise points of under water concrete pile foundation of bridge;

Prevention of underwater cast-in-situ concrete pile breaking and its processing

Taking the construction of rotational flow well of steelmaking and continuous casting in a certain steel company in Shanghai as an example, and based on introducing the geological condition of its engineering site, this paper expounds the top-down construction method of sidewall support with concrete piling.

The engineering practice of plain concrete pile composite foundation;

Application of plain concrete piles to treatment of deep and thick soft soil foundation;

The application of composite foundation of plain concrete pile in chemical equipment reformation;

The development of pre-tensioned prestressed concrete tubular pile in China;

Through an engineering example,a comprehensive treatment technology of wastewater from production of concrete tubular pile is introduced.

The advantages of this processing method of the concrete tubular pile are pollution-free,low noise and moderate cost of construction.
