Description
Technical field
The present invention relates to the protection technology field of side slope, refer in particular in a kind of dregs side slope anchor hole and the dual-purpose hole of osculum into
Hole technique.
Background technology
With the development of urban construction, a large amount of remaining body refuse mound product easily forms welding with filler wire.Welding with filler wire is as one
Kind is artificial to form mixture side slope, is that will banket to roll the physico-mechanical properties piled up, banketed step by step in forming process
Difference, therefore accumulate the welding with filler wire and unstable formed, therefore need to take welding with filler wire and reinforce prevention and control measure and administer, and
Anchor pole is a kind of common prevention and control reinforcement measure in slope treatment；Additionally due to the short texture and water penetration of welding with filler wire are strong,
Rainfall and the presence of underground water, the possibility that landslide or mud-stone flow disaster occur to inducing welding with filler wire increase, it is therefore desirable to
To welding with filler wire carry out drainage sunk well, except fill slope slope table lay gutter in addition to, additionally should in welding with filler wire slopes cloth
If In-pit water drainage hole.
Since the dregs mixture in welding with filler wire is loose, so when anchor pole and osculum are constructed, i.e., anchor hole and
In the pore forming process of In-pit water drainage hole, larger using conventional forming hole method difficulty, collapse hole, bit freezing easily occur for weak loose earth
Etc. accidents.
For the anchor hole pore-forming technique in Loose Slope, the patent for having related fields is studied, and includes construction
When take casing retaining wall and the methods of using self-feeding anchor pile drilling, it is contemplated that it is practical during welding with filler wire row's bolthole construction
On also need to carry out the construction of osculum, in based on analysis welding with filler wire on the basis of soil mass property, to reduce construction cost
And construction efficiency is improved, therefore the present invention has invented a kind of slag for the hole creating technology of anchor hole and osculum in welding with filler wire
Anchor hole and the pore-forming technique in the dual-purpose hole of osculum in native side slope.
