Description
Technical field
The present invention relates to bored tunnel technical field of construction, during bored tunnel, after caving in, such as
A kind of bored tunnel sump remedy method where reason landslide section and vault sinking section propose.
Background technique
In tunnel construction, landslide is one of most common geology harm.Once caving in, not only the duration is caused to prolong
Accidentally, engineering cost is significantly increased, and the life security of construction, technical staff can be jeopardized, also will cause construction quality
Hidden danger carrys out extreme difficulties to maintenance work belt, or even makes tunnel can not normal use.
The short and small tunnel that especially those height above sea level are not high, buried depth is shallower using New Austrian Tunneling Method when being excavated, due to up/down steps
Too long for gap, inverted arch arch is installed not in time, the reasons such as arch ring cannot be closed as early as possible, and secondary lining is not caught up with, then meets rainy season
Construction, rainwater are largely assembled in massif, and vault load-bearing increases severely, and are likely to result in tunnel and cave in, tunnel caves in
The direct result presented afterwards is that mountain upper ground surface huge pitfall occurs, and a large amount of soil bodys pour in hole, and landslide Duan Chuzhi steelframe is almost complete
Portion collapses, and cave in section front and rear sides vault sinking.
Currently, Tunnel Engineering Treatment for collapse mainly has the methods of poling board method, pipe shed method, freezing process, anchor pole method, cut and cover method,
But treatment effect is very different, cannot definitely guarantee safely.For standard construction, improve treatment effect, improves operation effect
Rate increases safety guarantee, and research and probe one kind is safe and effective, practicable Tunnel Landslide processing method is for reducing tunneling tunnel
The construction risk in road has very important meaning.
Summary of the invention
The object of the present invention is to provide a kind of bored tunnel sump remedy methods, its advantage is that securely and reliably, at low cost, energy
It is enough that timely and effectively the tunnel after landslide is handled, and make treated to cave in area with higher stability.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of bored tunnel sump remedy
Method, including following construction procedure:
Step A: preliminary bracing is carried out before construction；
Step B: the collapsing hole of tunnel top is closed；
Step C: backfill processing is carried out in hole to collapsing；
Step D: material spray filling is carried out in hole to collapsing；
Step E: injecting treatment is carried out in hole to collapsing.
Through the above technical solutions, the construction method is safe and reliable, at low cost, it can be timely and effectively to the tunnel after landslide
Road is handled, and makes treated to cave in area with higher stability.It is by preliminary bracing, to guarantee staff
Then safety during subsequent construction is closed the collapsing hole of tunnel top, prevent the soil body from occurring further
It collapses, then first passes through backfill processing, be filled to collapsing in hole, form it into the new soil body, then filled out again by material spray
It fills, makes to combine closely between the soil body around the soil body newly formed and tunnel, finally by slip casting operation, be sufficient filling with slurries
The gap location between the soil body around to the soil body and tunnel newly formed, plays the role of bonding, and form final reinforcing body,
Compared to direct slip casting, cost is lower, while stability is more preferably.
The present invention is further arranged to: the step A includes:
Step A1: prospecting massif original ground collapses range, sets up a cordon around massif pitfall, and protective net is arranged；
