Description

Rotary intelligent pile filling machine

Technical Field

The invention relates to the technical field of pile filling equipment, in particular to a rotary intelligent pile filling machine.

Background

Grouting operation is needed in the drilling construction process at present, the existing pile grouting operation mainly depends on matching of a crane and a grouting platform with a plurality of sections of iron guide pipes, and the plurality of sections of iron guide pipes are connected to be 30-50cm away from the bottom of a hole through threaded connection and rubber ring sealing; during pouring, the concrete is conveyed to the bottom of the hole through the sealed iron guide pipe, the buried depth is guaranteed to reach 6 meters, the guide pipe is pulled out through manual repeated measurement and checking, the buried depth is guaranteed to be not lower than 2 meters, the design pouring requirement is met through sequential circulating operation, the concrete is continuously poured through the ash bucket, and the concrete is continuously poured by utilizing the pressure difference between the inner concrete and the outer concrete of the guide pipe.

However, in the prior art, a crane is required to sequentially and circularly butt the guide pipes during pouring, the guide pipes need to be butted and the guide pipe screw threads need to be fastened by manpower in the installation process, the guide pipes are lifted up and then put down by the crane, the platform door is opened and closed by manpower in the process, the process is completely operated by manpower, the labor intensity of workers is high, and the labor cost is high.

All need artifical remaining when transporting and dismouting pipe lift by crane simultaneously, produce the injury to the operating personnel easily, the crane is hanging the heavy object and is touchhing near the operating personnel easily when rotatory, cause the injury to the operating personnel, dismouting pipe in-process, because the operating personnel is collided with very easily to iron pipe weight is big, cause operating personnel's personal harm, there is the effect of protecting the wall to the hole by the mud among the filling process, nevertheless unexpected hole collapse phenomenon can still appear, only can operate above the drill way during personnel's operation, in case the unexpected hole collapse appears and will cause major personnel's injury.

In addition, because the metal guide pipes are connected manually, the phenomenon of air leakage and water leakage caused by untight thread or damaged sealing rings sometimes occurs in connection of each section of guide pipe, and the pile filling quality is affected. The long-term friction with the concrete in pipe depressed part can cause the mill to leak, is difficult for the inspection to cause gas leakage water leakage phenomenon, influences and irritates a quality. In the existing pile grouting process, the concrete height measurement and the calculation of the buried depth of the guide pipe are both manual operations, and the problem of miscalculation exists, so that the guide pipe is pulled more or less, and the pile grouting quality is seriously influenced. The accident that the concrete cannot be poured and even the pipe is blocked occurs. And if no experienced staff carries out frequent measurement by using a special measuring rope in the process of pouring, whether the next work is needed or not is accurately calculated through the measured data, and the quality of the poured pile is greatly influenced by human factors in the process.

In the process of pouring, the crane is needed to be used for matching operation, so that the requirement on the site is strict, and the requirement on the working surface is larger, and if the site cannot meet the construction requirement of the crane, a forklift excavator is needed to be matched with the site to level the site. The requirement on the working environment is high, for example, the high-altitude obstacles cannot meet the construction requirement of a crane, the site is too soft, and the like, the production stop may be caused; in the construction, the pile foundation construction at the pier (platform) position needs cross operation, pouring tools (a guide pipe, a platform … and the like) need to be transported, the pouring is complicated, and the efficiency is too low to meet the production requirement of modernization and high efficiency.
