The invention discloses a water spray cutter head of a tube push bench. The water spray cutter head comprises a cutter head, long main cutters and short main cutters. The long main cutters and the short main cutters are distributed on the cutter head at intervals, tearing cutters are arranged among the long main cutters and the short main cutters and are higher than cutter bits of the long main cutters and cutter bits of the short main cutters, mud inlets are respectively formed in the long main cutters and the short main cutters, barriers capable of controlling opening and closing of the mud inlets are arranged on the mud inlets, water spray pipes are further annularly arranged on the cutter head, and the barriers and the water spray pipes are controlled by a controller. The water spray cutter head with the structure has the advantages that the tearing cutters are arranged among the long main cutters and the short main cutters and are higher than the cutter bits of the main cutters, obstacles can be cut in advance, the cutting efficiency can be improved, accordingly, the cutter bits of the main cutters can be protected, and damage to the cutter bits of the main cutters can be reduced; particularly, the water spray pipes are further annularly arranged on the cutter head, and water can be sprayed in cutting procedures, so that the cutting efficiency can be further improved.
Description
[0001] technical field [0002] The invention relates to a component for a pipe jacking machine, in particular to a cutting cutter head of a water jet pipe jacking machine. Background technique [0003] Pipe jacking machine is the construction equipment commonly used in trenchless construction of underground construction projects. With the continuous development of pipe jacking, pipe jacking construction technology has gradually developed into a non-excavation method based on the theory of air pressure balance, mud-water balance and earth pressure balance. Digging construction techniques. However, during the pipe jacking process of existing pipe jacking machines, the existence of underground obstacles may affect the normal jacking of the pipe jacking machine, which may not only damage the equipment, waste equipment investment costs, but also prolong the construction period, resulting in Waste of construction costs. Contents of the invention [0004] The technical pro...
