A method of ground connection wall construction using a slot milling machine under low headroom

Abstract

The invention discloses a method for ground connection wall construction using a slot milling machine under low headroom. The device includes a track and a construction module, the track is laid in a pilot hole, and the construction module includes a milling module, a slurry pumping module, The coil crane module and the accessory reel module, the milling and cutting module, the pumping module, the coil crane module and the accessory reel module are connected to each other in sequence from front to back, and are all arranged on the track. Module and accessory reel module connection. The invention miniaturizes and modularizes the trough forming equipment, satisfies the construction conditions of low headroom, realizes the construction of the ground connection wall in the low headroom, overcomes the defect that large-scale equipment cannot work under specific terrain, and has the advantages of convenient installation and trough forming It has the advantages of high efficiency, and can effectively avoid the shortcomings of frequent switching procedures during the construction of large equipment, and improve construction efficiency.

Description

technical field [0001] The invention relates to the technical field of underground construction, in particular to a method for constructing ground connection walls with a slot milling machine under low headroom. Background technique [0002] In the prior art, when constructing grooves in the underground ground wall, a rotary drilling rig is often used to form a plurality of rotary drilling holes in the groove section of the ground wall, and then an impact drill is used to hammer and hammer adjacent holes one by one from one end of the groove section to the other end. The partition wall between the two rotary drilling holes until a complete slot is formed; then the rotary drilling machine is converted into a clearing drill bit, and the rotary drilling machine is moved on the track, and the hoist is used to drive the clearing drill bit in the slot to punch up and down and move milling The small wall in the tank is left, and the sediment and pebbles in the tank are salvaged, an...

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
