Abstract
The utility model belongs to the technical field of public road bridge tunnel, specifically disclose a highway tunnel structure, include and protect the hunch, protect and encircle to the arc and protect the hunch both ends and describe for the step, it is equipped with main fender pile and supplementary fender pile below the tip of hunch to protect, main fender pile and supplementary fender pile link together, be equipped with the slide rail in the middle of protecting the hunch, be equipped with the liftable crane on the slide rail, supplementary fender pile is established between two main fender piles, protect encircle and the inboard of supplementary fender pile on be equipped with the waterproof layer. The utility model discloses simple structure, stable performance and with low costs.
Description
Technical field
This utility model belongs to highway bridge tunnel technical field, is specifically related to a kind of highway tunnel structure.
Background technology
When highway engineering adopts tunnel scheme to pass through massif, due to flat vertical limited index, it is difficult to avoid toe soil layer or sand bed, shrinking according to tunnel, hole heavy cut scheme passes through soil layer or sand bed, very easily causes cut slope too high, the problem that protection works amount is bigger, and construction and operations risks bigger；Carrying out the construction of dark hole according to New Austrian Tunneling Method and pass through soil layer or sand bed, ancillary method is more, and construction risk is big.Building mountain tunnel at sand bed or soil layer, adopt tradition conventional tunnel structure always to there are some unfavorable factors, therefore, a kind of new stake arch composite lining highway tunnel structure of necessary offer solves above-mentioned technical problem.
Utility model content
The purpose of this utility model is to provide the highway tunnel structure that a kind of simple in construction, stable performance and cost are low.
For achieving the above object, this utility model is by the following technical solutions: a kind of highway tunnel structure, including protecting arch, for arc and to protect arch two ends be step-like to protect arch；The end protecting arch is arranged below main fender pile and auxiliary fender pile；Main fender pile and auxiliary fender pile link together；Protecting and be provided with slide rail in the middle of arch, slide rail is provided with liftable crane；Auxiliary fender pile is located between two main fender piles；The inner side protecting arch and auxiliary fender pile is provided with waterproof layer.
Further, the bottom of waterproof layer is provided with downcomer.
Further, auxiliary fender pile is connected with main fender pile by connector.
Further, also including anchoring-bolt system, anchoring-bolt system is installed on the contact surface of auxiliary fender pile and main fender pile and is anchored at outside main fender pile through main fender pile.
Further, assist the top of fender pile higher than main fender pile.
Compared with prior art, the beneficial effects of the utility model are as follows: protect arch for arc and protect arch two ends be step-like, the end protecting arch is arranged below main fender pile and auxiliary fender pile, and main fender pile, auxiliary fender pile match with the stepped end protecting arch, strengthen the stability protecting arch；Main fender pile and auxiliary fender pile link together, it is prevented that fender pile generation relative displacement, strengthen the stability of tunnel structure；Protecting and be provided with slide rail in the middle of arch, slide rail is provided with liftable crane, and liftable crane can enter along slide rail and carry out in tunnel rescuing or safeguarding；The inner side protecting arch and auxiliary fender pile is provided with waterproof layer, improves the water resistance in tunnel；The bottom of waterproof layer is provided with downcomer, in time tunnel is carried out draining；Auxiliary fender pile is connected with main fender pile by connector, easy for installation and good fixing effect；Tunnel structure also includes anchoring-bolt system, and anchoring-bolt system is installed on the contact surface of auxiliary fender pile and main fender pile and is anchored at outside main fender pile through main fender pile, improves the stability in tunnel；The top of auxiliary fender pile is higher than main fender pile, it is simple to coordinate with protecting arch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of highway tunnel structure, as it is shown in figure 1, include protecting arch 3, protects arch 3 below original ground 1 and between the side slope 2 that is obliquely installed of both sides, and for arc and to protect arch 3 two ends be step-like to protect arch 3；The end protecting arch 3 is arranged below main fender pile 9 and auxiliary fender pile 7, and main fender pile 9, auxiliary fender pile 7 match with the stepped end protecting arch 3；Main fender pile 9 and auxiliary fender pile 7 link together；Protecting and be provided with slide rail 5 in the middle of arch 3, slide rail 5 is provided with liftable crane 6, and during use, liftable crane 6 can be movable so as to carry out rescuing or safeguarding along slide rail 5 in tunnel；Auxiliary fender pile 7 is located between two main fender piles 9；The inner side protecting arch 3 and auxiliary fender pile 7 is provided with waterproof layer 4.The bottom of waterproof layer 4 is provided with downcomer 11.Auxiliary fender pile 7 is connected with main fender pile 9 by connector 10.Highway tunnel structure also includes anchoring-bolt system 8, and anchoring-bolt system 8 is installed on the contact surface of auxiliary fender pile 7 and main fender pile 9 and is anchored in the native stone outside main fender pile 9 through main fender pile 9.The top of auxiliary fender pile 7 is higher than main fender pile 9.
