Description
Technical Field
The utility model belongs to the technical field of the building engineering construction, in particular to long spiral drilling bored concrete pile prevents surpassing system of irritating.
Background
When the long spiral drilling machine is used for construction of the long spiral drilling cast-in-place pile, the long spiral drilling machine is heavy, after drilling, hole cleaning and concrete pouring are finished, the long spiral drilling machine is inserted into the steel bar cage, and then the long spiral drilling machine is shifted to carry out construction of the next pile. Because the functions of the actual rooms are different, the stress of the actual rooms is different, and therefore the stress of the piles below the corresponding rooms is different. For example, the elevator car is deeper and the height of the top of the pile is lower. Whereas the rig displacements have to be performed on the same reference level. Therefore, when the elevation of the pile top is below the same horizontal reference surface, concrete is usually poured to the elevation of the pile top, then the elevation of the pile top is poured to the height of the same horizontal reference surface, and when the small excavator excavates the pile foundation platform, the pile head concrete of the multiple pouring parts is cut off by excavating the soil again. Generally, the concrete of the part needs to be over-poured by 1500 mm-4000 mm compared with the piles required by design, so that the over-pouring of the over-poured concrete is caused during construction, the using amount of the over-poured concrete is increased, the waste phenomenon is caused, the pile head is transported away after the pile is cut, and the energy-saving and environment-friendly effects are achieved.
The design standard height difference of the pile top of the meeting hall of a certain project is different, and the pile top height is-6.600 (53.8 meters), -7.800 (52.7 meters), -8.000 (53.5 meters), -8.300 (53.2 meters), -8.600 (52.9 meters), -9.600 (51.9 meters). As the same reference horizontal plane of the top elevation of the bottom plate of the bearing platform is-6.600 (54.9 meters), and the thickness of the basement plate is 300mm, the construction elevation of the piling construction reference working surface is-6.600 (54.9 meters). The project is constructed by a long spiral drilling machine, empty piles cannot be reserved (namely concrete cannot be poured from-6.600 to the height of the pile top), and accordingly excessive pouring waste phenomenon exists in piles with the height of-7.800 (52.7 m), -8.000 (53.5 m), -8.300 (53.2 m), -8.600 (52.9 m) and-9.600 (51.9 m). If partial concrete is not poured from-6.600 to the elevation of the pile top, the concrete consumption can be saved, but sediment and underground water generated by hole collapse and drilling construction of the pile top cannot be discharged (when the concrete is poured to the same horizontal reference surface in long spiral bored pile construction, the sediment and the redundant underground water are discharged), if the concrete is poured to the elevation of the pile top, the sediment and the underground water cannot be discharged, and after the concrete pile is poured to the pile hole, the strength of the concrete pile is reduced, so that the actual strength of the concrete pile is influenced. How to guarantee the actual pouring strength of the pile concrete and not to pour more concrete, the problem needs to be solved by improving or developing a novel drilling machine.
