Dual-purpose type pipe jacking machine head

Abstract

The invention discloses a dual-purpose type pipe jacking machine head. The dual-purpose type pipe jacking machine head can be used for carrying out engineering construction by applying a spiral pipe jacking method and can also be used for carrying out engineering construction by applying a pipe jacking method; the dual-purpose type pipe jacking machine head comprises a cutterhead, a cutterhead shell body, a machine head shell body, and a dreg discharging system, a transmission device, a deviation correcting device, a speed reducer and a prime mover which are arranged and distributed in the machine head shell body; the prime mover is connected with the transmission device through the speed reducer; the cutterhead and the transmission device are mounted on the cutterhead shell body through a key connection manner; the cutterhead shell body is connected with the machine head shell body through the deviation correcting device. According to the dual-purpose type pipe jacking machine head, the disadvantage that the spiral pipe jacking method cannot be constructed in a hard formation is overcome, and the defects that the pipe jacking method occupies large space and field in a construction process under soft geological conditions, the construction cost is high and the environment pollution is great are also overcome; the adaptability of equipment under different formation conditions is improved.

Description

technical field [0001] The invention relates to a dual-purpose pipe jacking head, in particular to a device capable of performing spiral blade soil discharge and balanced pipe jacking at the same time, and belongs to the technical field of pipe jacking heads. Background technique [0002] With the acceleration of urban construction and the strengthening of people's awareness of environmental protection, it is necessary to lay a large number of small-diameter rain and sewage diversion pipes, which makes the construction of pipe jacking machines more and more extensive. Although pipe jacking machines have the advantages of adapting to wide geological conditions, the construction of pipe jacking machines The construction speed is slow, and a large amount of mud is required to carry slag during construction. The mud not only pollutes the environment, but also needs to arrange mud treatment facilities at the construction site, thus occupying a lot of space and site. [0003] At p...

[0002] With the acceleration of urban construction and the strengthening of people's awareness of environmental protection, it is necessary to lay a large number of small-diameter rain and sewage diversion pipes, which makes the construction of pipe jacking machines more and more extensive. Although pipe jacking machines have the advantages of adapting to wide geological conditions, the construction of pipe jacking machines The construction speed is slow, and a large amount of mud is required to carry slag during construction. The mud not only pollutes the environment, but also needs to arrange mud treatment facilities at the construction site, thus occupying a lot of space and site

[0003] At present, although there are screw pipe jacking machines with fast construction speed, the existing screw pipe jacking machines can only be constructed under the geological conditions of soft soil layer and no groundwater or low groundwater content, and the underground soil quality is uncertain and unstable. Due to its unique characteristics, the danger of this construction method is exacerbated, and construction accidents in which the machine head is buried often occur, resulting in major engineering losses.
