Problems solved by technology

[0002] At present, ultra-deep and large-section excavation hole protection wall technology includes karst formation pile hole protection wall structure, ultra-deep large cross-section square support pile and its construction method, karst formation pile hole protection wall structure, which can consolidate unstable and loose strata into one, and can Effectively enhance the stability of the hole wall, but because this technology is excavated in sections and retaining the wall, it is difficult to control the quicksand in the excavation section, and the lower section can only be opened after the cement slurry pressed into the upper section has consolidated to a certain strength. Excavation, continuous construction is not possible, and the construction speed is slow; while the ultra-deep large-section square support pile and its construction method can ensure the construction quality of the pile hole retaining wall, and can ensure the safety of manual digging. The retaining wall is easy to operate, but it must be segmented Construction, it is difficult to control the quicksand in the excavation section, and the excavation of the lower section can only be carried out after the concrete of the upper section of the retaining wall has consolidated to a certain strength, and continuous construction is not possible, and the construction speed is slow

Embodiment Construction

[0012] The invention is attached figure 1 , 2 , 3, and 4, the equipment is composed of a circular mouth guard 1, a sawtooth strip guard 2 and a rotating casing 3 with climbing gear rollers, one end of the sawtooth strip guard 2 is connected with the circular mouth guard 1, The other end is connected to the rotating casing 3 with climbing gear rollers. The circular mouth guard 1 has a round opening 11 in the center. The sawtooth strip guard 2 forms a wall cylinder, and the support for the hole wall is firm, safe and reliable. Fixing holes 21 and fixed blocks 22 are set on the strip guard 2, and the fixed blocks 22 are separated on both sides of the sawtooth strip guard 2, and holes 23 on the stop 22 on one side can be connected with bolts 24 and sawtooth strip guards. The plates 2 are connected, the serrations 25 on both sides of the saw-toothed guard plate 2 are meshed and buckled to form a cylinder, the anchor rod is inserted to the periphery of the hole wall through the fi...
