Abstract
The utility model discloses the highway tunnel structure of a kind of pair of fender pile braced structures, highway tunnel structure, comprise and protect arch, the main fender pile protecting arch two ends described in being supported in and the secondary fender pile protected described in being supported between arch two ends, protect arch and be provided with in both sides for by the plane structure supported for circular arc, described time fender pile is supported in the described plane structure of protecting arch, described plane structure and the same side arc length of protecting between arch abutment portion is 1/5th of Inner arc overall length, the utility model is applicable to hole partial sector certain thickness sand bed or soil layer, barrel part is the geological conditions of stone matter country rock, and structure is simple, cost is low.
Description
Technical field
The utility model relates to highway tunnel building technology, particularly relates to the highway tunnel structure of a kind of pair of fender pile braced structures.
Technical background
In the engineering in urban construction tunnel, often run into big vast alluviation silty clay, sandy silt soil stratum, soil layer (or sand bed) is passed through according to Wan Jin hole, tunnel, hole heavy cut scheme, very easily cause cut slope too high, the problem that preventive works amount is larger, destroy greatly natural environment, the stability of side slope is difficult to ensure, and construction and operations risks larger; Carry out tunnel and boring construction according to traditional New Austrian Tunneling Method, ancillary method is more, and construction risk is large, and design difficulty is larger.
A kind of highway tunnel structure is described, to solve the problems of the technologies described above in the patent document of application number 201210304864.3.Wherein, for preventing surrouding rock deformation or caving in, have employed liner structure, but cost is too high, in this highway tunnel structure, the utility model provides the highway tunnel structure of a kind of pair of fender pile braced structures, and structure is simple, and cost is low, can reach human and vehicle shunting and travel.
Summary of the invention
The problem that the utility model solves is: provide a kind of and be applicable to the highway tunnel with two fender pile braced structures that hole partial sector has certain thickness sand bed or soil layer, barrel part is stone matter country rock.
The technical scheme that the utility model is taked is:. a kind of highway tunnel structure, comprise protect arch, be supported in described in protect arch two ends main fender pile and the secondary fender pile that protects described in being supported between arch two ends, protect arch and be provided with in both sides for by the plane structure supported for circular arc, described time fender pile is supported in the described plane structure of protecting arch, and described plane structure and the same side arc length of protecting between arch abutment portion is 1/5th of Inner arc overall length.This structure is applicable to the geological conditions that hole partial sector has certain thickness sand bed or soil layer, barrel part is stone matter country rock, after protecting arch construction complete, protect dome portions and can carry out backfill stone soil immediately, shorten the open-assembly time of side slope, improve working security, and be easy to recover original place looks and vegetation, during operation without avalanche, broken fall or slope instability etc. jeopardize the engineering disease of traffic safety, and structure is simple.
Further, the angular range protecting arch circular arc described in is 120-140 degree.Circular arc can be made like this to protect arch is partial to flat, is conducive to time fender pile and supports, and the pressure shared on primary and secondary fender pile is reasonable, and structure is more firm.
Further, described highway tunnel structure also comprises the anchoring-bolt system be fixed on described fender pile, and described anchoring-bolt system is installed on the inner surface of described fender pile, and the Shi Tuzhong running through described fender pile and be anchored in outside fender pile.
Further, the road surfacing layer of concrete between arch is protected in both sides time, and layer of concrete is that middle high both sides are low, is provided with sewer pipe at low side.For preventing surface gathered water, be conducive to safe driving of vehicle.
Further, laying mixed dirt bed between the main fender pile in the same side and secondary fender pile.This structure can be used for walkway in tunnel and Refuge Point.

Detailed description of the invention
Embodiment 1 as shown in the figure, highway tunnel structure, comprise and protect arch 1, the main fender pile 2 protecting arch two ends described in being supported in and the secondary fender pile 3 protected described in being supported between arch two ends, protect arch 1 be circular arc and be provided with in both sides for by the plane structure 10 supported, protect arch 1 below original ground 7 and between both sides side slope 6, described two ends protecting arch 1 are set up on vertical described fender pile 2, for carrying the stone soil protecting and fill out above arch 1 and put, avoid caving in, ensure the safety in main hole, tunnel, described time fender pile 3 is supported in the described plane structure 10 of protecting arch 1, play the effect of supplemental support.For the ease of main fender pile 2 and protect connection effective, firm between arch 1, secondary fender pile 3 and protect connection effective, firm between arch 1, be equipped with shaped steel or reinforcing cage in described main fender pile 2 and time fender pile 3, and form via concrete-agitating soil, cement high-pressure rotary-spray or concreting.Described plane structure 10 and the same side arc length of protecting between arch 1 end is 1/5th of Inner arc overall length; Optimum selecting ground, the angular range protecting arch circular arc is 120-140 degree, is conducive to time fender pile and supports, and the pressure shared on primary and secondary fender pile is reasonable, and structure is more firm.In order to improve the retaining design stability in tunnel, ensure working security, reduce unstability risk, described main fender pile 2 is fixedly installed anchoring-bolt system 8, described anchoring-bolt system 8 is installed on the inner surface of described main fender pile 2, and the Shi Tuzhong running through described main fender pile 2 and be anchored in outside main fender pile 2.
In addition, in order to prevent surface gathered water, the road surfacing layer of concrete 4 between arch 3 is protected in both sides time, and layer of concrete 4 is that middle high both sides are low, is provided with sewer pipe 11 at low side.
In addition, laying mixed dirt bed 5 between the main fender pile in the same side and secondary fender pile.This structure can be used for walkway in tunnel and Refuge Point.
The utility model is applicable to the geological conditions that hole partial sector has certain thickness sand bed or soil layer, barrel part is stone matter country rock, after protecting arch construction complete, protect dome portions and can carry out backfill stone soil immediately, shorten the open-assembly time of side slope, improve working security, and be easy to recover original place looks and vegetation, during operation without avalanche, broken fall or slope instability etc. jeopardize the engineering disease of traffic safety, and structure is simple, cost is low.
