Construction Monitoring of Concrete Piles from quangongzi's blog

Related links: Concrete concrete pile is suitable for dealing with the bearing capacity of the lower cohesive soil, silt and has been self-reinforced solid fill and other foundations. For the foundation can not meet the design requirements of the road section of the foundation treatment, taking into account the geological conditions and construction conditions, the foundation treatment using a concrete pile. The concrete pile should be tested to test its construction technology and treatment effect. Concrete concrete pile construction should be carried out after the detection, the detection value shall not be less than the design of the composite foundation of the composite capacity of the basic allowable value of the design to achieve the design of the bearing capacity before the foundation of the construction. It is a combination of Lianhuo Expressway Luoyang to Sanmenxia section to expand the construction experience, in the construction program and process flow to talk about the quality of concrete pile construction quality control.Road Sealing Machine - Road Machinery Equipment Manufacturers - Doan Machinery

The surface of the pile and the slope should be cleaned before the table, the leveling site, excavation of the first step, and then backfill tamping, rolling to the original surface, and then the concrete pile construction, pile The top elevation is lower than the surface 25cm, easy to construction pile cap. Using the total station for pile stakeout, the error shall not be greater than ± 5cm, marked with white gray point, the pile layout by square.

Test pile. The concrete pile should be tested before construction to determine the construction technical parameters. The position of the test pile is determined within the scope of the design paragraph. During the construction process, the project department, the supervisor full station, the concrete mixing, the hole, the hole spacing and the pouring concrete are strictly in accordance with the standard construction. Laying in accordance with the number of test pile 2 and the design of pile spacing (260cm) was square pile piles. When lofting, mark the pits with white ash. The pile spacing, pile length and pile diameter forming were measured during the process of piling, and the two test piles were carried out in the process of pouring concrete. The data were recorded during the construction of the test pile, and the actual construction reference was obtained. After the test pile concrete reaches 7 days strength, the test pile is tested, and the test pile process is summarized to determine the reasonable packing quantity, filling speed and vibration time, according to the results of the concrete concrete pile construction.
