Modular groove milling device for underground diaphragm wall construction

Abstract

The invention discloses a modular groove milling device for underground diaphragm wall construction, which comprises a track and a device module, the track is laid in a pilot tunnel, and the device module comprises a milling module, a slurry pumping module, a rolling and hoisting module and an accessory reel module. The milling module, the slurry pumping module, the rolling and hoisting module and the accessory reel module are sequentially connected with one another from front to back and are all arranged on the track, and the slurry pumping module is connected with the milling module, the rolling and hoisting module and the accessory reel module. Grooving equipment is miniaturized and modularized, the low-clearance construction condition is met, diaphragm wall construction at low clearance is achieved, the defect that large equipment cannot work under the specific terrain is overcome, meanwhile, the modular groove milling device has advantages that installation is convenient and fast, and the grooving efficiency is high, the defect that working procedures are frequently switched during construction of large equipment can be effectively overcome, and the construction efficiency is improved.

Description

Technical field [0001] The present invention relates to the technical field of underground construction apparatus, and more particularly to a modular milling groove device for continuous wall construction underground. Background technique [0002] When the prior art is in the underground, a plurality of cyclone drilled holes are formed in a plurality of cyclo drilling holes in the ground, and then use the impact drill from one end of the slot section to impact adjacent The partition wall between the two spin drilling until the complete slot; then convert the roller rig to change the hole drill bit, translate on the track through the cyclone, using the hoisting machine to drive the hole drill bit to the groove up and down, down, cut the movement milling The small wall in the residual groove, and salvage the groove and pebbles, and finally form a complete rectangular unit slot. [0003] The coherent drilling machine used by the prior art, the construction process of the impact dril...

AI Technical Summary

Problems solved by technology

[0003] The prior art employs a construction process in which the rotary drilling rig and the percussion drilling rig alternately form slots, which has the disadvantages of cumbersome process, frequent process changes, and low slotting efficiency. Faults such as stuck hammer and dropped drill

If the operation is not done properly, it may even damage the groove wall of the ground connection wall, increasing the construction risk

At the same time, some terrain restrictions make it impossible to use equipment such as rotary drilling rigs and impact drilling rigs for construction.

[0004] The existing equipment for slot milling construction from the ground has no environmental restrictions, and the equipment adopts a high vertical structure, so it has the limitations of being too large and requiring a high clear height, and due to equipment functions and other structural limitations, It also cannot effectively achieve miniaturization, so it cannot support low headroom construction
