Reinforced concrete slab has the characteristics of simple construction, short duty cycle and so on. It has been widely used in foundation pit. However, due to the common use of reinforced concrete piles of hammering method, vibration and noise, while the process of squeezing pile is also more serious in urban engineering subject to certain restrictions.
In addition, its production is generally prefabricated in the factory, and then transported to the site, the cost of slightly higher than the pile. But because of its cross-sectional shape and reinforcement of the pile pile force is more reasonable and can be designed according to need, has been able to produce a larger thickness (such as the thickness of more than 500mm) pile. And hydraulic static pile driving equipment, so in the foundation pit engineering is still supporting the use of a wall form.
