Background technique

The quality of pile foundation construction is an important manifestation of the specialization of a photovoltaic engineering company. How to achieve high-quality, efficient and fast construction of pile foundations has become a problem to be solved in the construction of photovoltaic projects.

Whether in domestic projects or international projects, most of the current pile foundation construction templates use corrugated pipes as pile foundation construction molds. There is no good pile foundation construction mold, and corrugated pipes are used as construction molds, which have insufficient rigidity, poor stability, and joints. There are large gaps, and during the construction process, the workers' construction concepts and procedures are fixed, the construction efficiency is extremely slow, and they cannot understand and implement the operation process formulated by the project department. As a result, the appearance quality of the pile foundation is poor after pouring and forming, and the verticality of the pile foundation and the deviation of the pile position are relatively large. In order to change the status quo, only new tools can be made. By using the superiority of the new tools, the status quo can be changed by use, thereby improving production efficiency.

use case

When in use, before the construction of the pile foundation, the site around the hole of the pile foundation is simply artificially leveled, and the soil in the hole is manually cleaned. In order to ensure that the gap between the bottom of the formwork and the hole does not turn over, the pile foundation is poured in layers. For the first pouring, all the pile foundations are poured until the ground is level. After the ground is leveled, the cylinder mold is installed. , in this process, the concrete in the pile hole is allowed to condense, and after the cylinder body mold is installed, the concrete in the pile hole has a certain bearing capacity at this moment. Before the pile hole concrete reaches the initial setting, start pouring the ground pile body concrete, pour the concrete into the mold, vibrate, collect the slurry and clean the surface to complete the operation. The appearance quality of the finished pile body, the verticality of the pile body, and the smoothness of the surface have all been greatly improved.
