Description
Technical Field
The utility model belongs to the field of mechanical jacking pipes, and particularly relates to a jacking structure of a rigid stratum mechanical jacking pipe.
Background
The rain sewage pipeline is used as a part of underground engineering, and is a main means for solving the problems of urban waterlogging disasters, rain runoff pollution, water resource shortage and the like. With the urban construction needs, the reconstruction of old urban areas and the great development of public utilities, the diameter of pipelines is increased, the construction length is longer and longer, and meanwhile, the construction difficulty is increased due to the diversity and complexity of urban environments and geological environments. The pipe jacking method construction is the most commonly used and efficient method at present because the pipe jacking method construction can reduce the earthwork quantity and has small influence on the environment of the ground building structure.
The current pipe jacking method applied to underground pipeline construction comprises two types of mechanical pipe jacking and manual pipe jacking. The manual pipe jacking has the advantages of economy and convenience when the buried depth is shallow, the underground water level is deep and the construction distance is short, but the manual pipe jacking requires large manpower in the pipeline engineering with long distance, deep burying, complex geological environment and difficult dewatering, and has low efficiency and low safety. The mechanical jacking pipe is suitable for various geological environments, is widely applied, is safe and controllable in construction of deep buried pipelines such as roads, rivers, railways, ground buildings, underground structures and various underground pipelines, is not influenced by seasonal factors, and has high construction efficiency.
The mechanical pipe jacking is realized by installing equipment such as a track, a jack and the like in a working well, cutting the soil in front of the pipe jacking machine, pushing the pipe jacking machine and the prefabricated pipe into a receiving well according to a design axis under the action of the jack, and burying a pipeline with a certain function underground. However, in the hard stratum, irregular vibration occurs to the pipe jacking machine or the pipeline (the front three sections and the pipe jacking machine fixedly connected pipeline) due to the reaction force of pebbles or rock layers on cutting of the cutterhead during primary jacking, so that the machine head deviates from a design axis, the construction efficiency is affected, and the correction difficulty is increased in the follow-up jacking process. The existing reinforcing method adopted on the construction site needs to increase the labor investment, affects the construction efficiency to a certain extent and is unsafe, and meanwhile, the vibration reduction effect is limited.
Therefore, a new jacking structure is needed for the hard stratum mechanical jacking pipe.
