Abstract
The utility model discloses a kind of tunnel structure that can reduce slope excavating and, including the tunnel body intersected with side slope, tunnel body is provided with the reinforced concrete soil suite arch for being provided with and matching with tunnel body vault at the top of the concrete guard wall arranged vertically, concrete guard wall close to the side wall of side slope.The utility model solves the problems, such as the environmental disruption that extensive excavation slope is brought using half dark half bright tunnel, and is changed from passive to active compared with conventional method, shortens the construction period, improves project benefit.
Description
Technical field
The utility model is related to tunnel and its technical field of construction, and in particular to a kind of to reduce the tunnel knot of slope excavating
Structure.
Background technology
In Hydraulic and Hydro-Power Engineering construction and running, most of power stations are located at mountain area, in highway geometry, tunnel axle
In the case that line adjustment is difficult, Shang Ba highways and Chang Nei highways are during excavating or biasing serious tunnel mouth hanging, unavoidable shape
Excavated into Slope with multi-step, then need to carry out dam public affairs in excavation formation in side slope position in the case of original excavation circuit is unalterable
Road Huo Changnei highways, when being excavated in side slope position, traditional scheme is by all cubic meters of wholes of predetermined excavation position
Excavate, form Shang Ba highway Huo Changnei highways builds space, the slope after excavation is then subjected to supporting, severe is excavated not only
A large amount of original vegetation can be destroyed, high slope rockmass is also thus brought, increases construction fussy degree, and have delayed the duration, together
When also increase investment.For medium and small project, the problem of reducing slope excavating, investment reduction and shortening duration increasingly causes
How the attention of people, take maximally effective processing scheme both to meet requirement of engineering, and ring water guaranteed request can be met again, becomes
Passive is active, is one of the problem of designer's emphasis considers, but does not have corresponding technical scheme in the prior art.
Utility model content
The utility model aim to provide it is a kind of can reduce the tunnel structure of slope excavating, built with solving existing sharp hydroelectric project
If middle Slope with multi-step difficulty of construction existing when excavating is big, construction period length, construction investment is big, vegetation deterioration is serious etc. asks
Topic.
The utility model is achieved by following technical solution：
A kind of to reduce the tunnel structure of slope excavating, including the tunnel body intersected with side slope, tunnel body is close to side
The side wall on slope is provided with the top of the concrete guard wall arranged vertically, concrete guard wall provided with the reinforcing bar matched with tunnel body vault
Concrete jacket encircles.
The tunnel body vault is provided with horizontal and vertical side slope slip casting solidification anti-skid structure.
The tunnel inner body wall is provided with the reinforced concrete lining layer layer fitted with it.
The tunnel body outer wall is provided with the steelframe fitted with it and supported.
The concrete guard wall bottom is provided with some friction piles.
Concrete guard wall is inserted on the friction pile top.
The beneficial effects of the utility model are：
Compared with prior art, what the utility model was provided can reduce the tunnel structure of slope excavating, using hazy
Tunnel structure form, in the case where Shang Ba highways, Chang Nei highways, tunnel mouth hanging equal-pitch contour are difficult, by Shang Ba highways
Side is set hazy compared with positions such as tunnel mouth hangings serious compared with high slope section, bias on the inside of high slope section, Chang Nei highways
Tunnel structure, reduces excavation and the supporting of side slope, and then ensures the safety of highway communication or tunnel mouth hanging.Solve extensive
The environmental disruption problem that excavation slope is brought, changes from passive to active compared with conventional method, shortens the construction period, improve work
Cheng Xiaoyi.
