In the tool platform, the guide pipe positioning platform is connected with the frame beam through the angle steel of the limiting device, and the angle steel and the frame beam form a clamping groove, so that the sliding and overturning of the guide pipe limiting platform can be limited, and the guide pipe platform can slide in the clamping groove in the process of procedure conversion;
3. the measures and structures used by the two tools for lengthening the reinforcement cage and positioning the concrete pouring guide pipe in the construction of the cast-in-place pile are often independent, and each procedure conversion needs to be firstly lifted away from the measure structure of the previous procedure and then lifted in place, so that the efficiency is low. This application instrument formula platform is in the same place the platform integration of these two processes, only needs to slide the end with pipe location platform at steel reinforcement cage extension in-process, does not hinder the operation of this process, only needs to slide pipe location platform to protect a section of thick bamboo drill way when getting into next process, and is high-efficient swift.
The invention has the beneficial effects that:
1. is safe and reliable. The safety risk caused by the sudden sinking of the steel casing is avoided;
2. high efficiency and rapidness. A safe and reliable operation platform is provided for operators, the measures and components required for the operators to operate are simple and light, and the operation efficiency is greatly improved;
3. the field operation is reduced, and the economic efficiency is higher. The measures and structures required by the two procedures of placing the reinforcement cage and pouring concrete are integrated on one platform, so that the hoisting operation during procedure conversion is reduced, and the consumption of energy and equipment is saved.
