Embodiment Construction
[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.
[0028] refer to figure 1, the preferred embodiment of the present invention provides a small shield machine, which includes a hollow cylindrical outer shaft cylinder 10, and a partition plate 11 is fixed inside the outer shaft cylinder 10 to separate the shaft cavity of the outer shaft cylinder 10. It is a muddy water cabin 101 and an installation cabin 102 arranged in sequence along the axial direction and not connected. The open end of muddy water cabin 101 is fixedly provided with filter screen cover 30, and the outer side of filter screen cover 30 is provided with cutter head 20 at intervals, forms crushing cabin between cutter head 20 and filter screen cover 30, and is scattered on cutter head 20 and is provided with The reaming knife 22 for reaming and dete...

The invention discloses a small shield tunneling machine. The small shield tunneling machine comprises an outer shaft barrel, and a partition plate is arranged in the outer shaft barrel to divide a shaft cavity of the outer shaft barrel into a muddy water cabin and a mounting cabin. A filter screen cover is arranged at the opening end of the muddy water cabin, cutter heads are arranged on the outer side of the filter screen cover at intervals, and a crushing cabin is formed between the cutter heads and the filter screen cover; and broaching cutters, scraping cutters and pressure drilling cutters are distributed on the cutter heads, and the crushing cabin is used for further crushing mud blocks and broken stones entering the crushing cabin under matched extrusion of the filter screen cover and the cutter heads, so that after passing through the filter screen cover, the water enters the muddy water cabin communicates with the filter screen cover to be discharged. A power system and a water inlet and slurry discharge system are arranged in the mounting cabin, the power system penetrates through the muddy water cabin and the filter screen cover in the axial direction and then is connected with the cutter heads, and the water inlet and slurry discharge system is arranged on the periphery of the power system and used for supplying external flushing water into the crushing cabin and discharging muddy water in the muddy water cabin out of the shield tunneling machine. The small shield tunneling machine is wide in application range and capable of effectively preventing the water inlet and slurry discharge system from being blocked.
Description
technical field [0001] The invention relates to the technical field of hydropower pipeline construction, in particular to a small-sized shield machine. Background technique [0002] During the construction of hydropower pipelines such as subways, railways, highways, and municipal utilities, the existing general construction method is: firstly, semi-closed excavation is carried out at the position where the hydropower pipeline needs to be laid, that is, the inner concave is excavated from top to bottom along the length direction of the pipeline laying. In this construction method, the labor intensity of workers is very high, the construction progress is low, and the construction quality is poor. In view of the technical problems existing in the existing construction methods, a small shield machine similar to the shield machine for tunnel excavation is invented. [0003] The small shield machine has a simple structure and a single function, and can only be used alone in mud s...
