Embodiment Construction

[0015] The accompanying drawing shows a specific embodiment of the present invention, which includes a slurry supply system, a guide system and an excavation system.

[0016] 1. Pulp supply system:

[0017] The slurry supply system is composed of a slurry supply hose 1, a slurry supply pipe 2, a water spray nozzle 8, a side nozzle 6, a high pressure slurry pump and other pipelines.

[0018] The slurry supplied by the high-pressure mud pump is sprayed from the water spray nozzle. The slurry sprayed from the water spray nozzle and the rotating scimitar cut the formation to make slurry. The slurry containing mud sand overflows from the tank and naturally flows back to the sedimentation tank, where it settles. After that, the slurry returns to the storage tank, and then the high-pressure mud pump in the storage tank supplies slurry to the tank, and so on.

[0019] The function of the side spray nozzle is to flush the mud partitions on both sides of the double-numbered trough section, and ...

Abstract

The invention discloses a double-shaft groove forming machine, which is characterized in that: the bottom end of the groove forming machine is provided with two power shafts (12) which rotate in opposite directions; the power shafts (12) are provided with bent blades; the rotating power of the two power shafts is from a submersible motor (5) in the middle; a water spray nozzle (8) is positioned on a horizontal pipe on the upper side of the power shafts; groove forming slurry is supplied by a high-pressure mud pump, and the slurry passes through a slurry supply hose and a slurry pipe and then is jetted through the water spray nozzle (8); and a guide rail (3) and a guide plate (7) complete the guidance of the groove forming machine together. The double-shaft groove forming machine is a special machine for building underground continuous walls.

Description

1. Technical Field [0001] The invention relates to a slotting machine, in particular to a twin-shaft slotting machine for underground continuous walls. 2. Background technology: [0002] At present, most of the trough forming equipment for the construction of underground continuous walls have the characteristics of shallow trough depth, low efficiency, expensive equipment and complex structure. 3. Summary of the invention: [0003] The present invention makes up for the shortcomings of the above groove forming equipment, and provides a double-shaft groove forming machine with high efficiency, low cost, large groove depth and simple structure. [0004] The present invention is realized through the following technical solutions: [0005] A dual-shaft slotting machine, which is special in that: the bottom end of the slotting machine is equipped with two power shafts 12 that rotate in opposite directions. The power shafts are equipped with scimitars. The rotation force of the two power s...
