Description
Technical field
The invention belongs to tunnel support fields, more particularly to a kind of combined supporting for concrete pipe sheet anchor pole deviation
Structure.
Background technology
With the aggravation of Urbanization in China, the development of urban track traffic is growing day by day, by 2015, China's rail
Road traffic total kilometrage reaches 3286 kilometers, and counting oneself has 25 112 circuits of city to be open to traffic operation.And the traffic of stream of people in rush hour is dredged
For dissipating and fast going on a journey, Underground Rail Transit is more advantageous compared to road traffic, and shield construction is Underground Rail Transit
Main engineering method in construction.In addition, with the promotion of Chinese Machinery Industry upgrading and construction technology level, shield tunnel tends to
Great burying develops.To get over river tunnel over strait and coal mine tunnel under deep earth as representative, the developing direction of great burying shield tunnel from now on.Tunnel
Road design of its support is overly conservative under certain conditions, causes to waste, however in some conditions again due to structure design of tunnel mistake
In weakness, there are larger security risks, and larger security risk is brought to the construction and the operation in later stage of Tunnel Engineering.Mesh
Preceding main method for tunnel construction has Mining Method, cut and cover method, shield method, underground diaphragm wall method, immersed tunnelling method etc..
Shield duct piece is the main mounting structure of shield-tunneling construction, is the innermost layer barrier in tunnel, carries and resists soil layer pressure
The effect of power, groundwater pressure and some special loads.Shield duct piece is the permanent lining, secondary lining structure of shield tunnel, shield pipe
Tablet quality is directly related to the total quality and safety in tunnel, influences the water resistance and endurance quality in tunnel.Shield duct piece
The high-strength water-tight concrete of generally use is produced, to ensure that reliable load and water resistance, production mainly utilize finished product section of jurisdiction
Mold is i.e. plastic after sealing placing concrete.
Anchor pole is the most basic component part of roadway support in contemporary coal mine, it is by the surrounding rock consolidation in tunnel one
It rises, makes country rock itself supporting itself.Present anchor pole is applied not only to mine, is also used in engineering technology, side slope, tunnel, dam body
Carry out main body reinforcing.Anchor pole is connect as the tensional element for going deep into stratum, its one end with engineering structure, and the other end gos deep into stratum
In, whole anchor pole is divided into free segment and anchoring section, and free segment refers to the region that the pulling force at anchor pole head is reached to anchoring body, work(
Can be that prestressing force is applied to anchor pole.Anchor pole is connect as the tensional element for going deep into stratum, its one end with engineering structure, the other end
Go deep into stratum, whole anchor pole is divided into free segment and anchoring section, and free segment refers to that the pulling force at anchor pole head is reached anchoring body
Region, function are to apply prestressing force to anchor pole；Anchoring section refers to the region that cement slurry bonds presstressed reinforcing steel and soil layer,
Function is to increase the bonding rubbing action of anchoring body and soil layer, increases the pressure-bearing effect of anchoring body, the pulling force of free segment is passed
To soil body depths.
In the 1960s, Austrian engineer is on the basis of engineering actual combat, it is proposed that theory of new Austrian tunnelling method, the theory are strong
It adjusts and using self carries out roadway support, be not traditional to stablize the tunnel after excavating by supporting construction
Road.From New Austrian Tunneling Method propose since, it is worldwide from surrounding rock supporting technology burst out formula development.It is soft that Dong Fangting proposes relaxation zone
The weak wrong support theory of country rock spray, the theory think relaxation zone can occur in hole week after being excavated with road.The broken swollen change of Broken Zone Surrounding Rock
Shape is only the main object of tunnel support, and soft rock tunnel relaxation zone range is generally large, " large deformation, difficult supporting ＂ outstanding problems.
The maximum feature of Norwegian law (abbreviation NTM) is using steel fiber reinforced shotcerte as permanent support.Wet shot steel
Fiber concrete shows that jet power is strong better than the main aspect of common pneumatically placed concrete, and rebound degree is low, uniform quality, ring
Border condition is good, job safety, it is not necessary to carry out anti-corrosion treatment, can prevent from being electrolysed and preventing accelerated corrosion.Steel fibre is reinforced
Method can save labour.Fibrous concrete can be such that stiffener is distributed on entire rock mass, and conventional grid method for strengthening
The lining cutting of construction is in undulating on scraggly rock mass, has more or less error amount with the calibration line of name.
Ductule support reinforcement is suitable for weak surrounding rock, fault belt and the shallow embedding location etc. of rock joint development.It is small
Conduit supporting is similar to pipe shed support principle, and ductule is laid in a ring on the outside of excavation contour line, becomes annular Load -carring arch.
Steel tube shed and ductule can act as support action in the tunnel of Unfavorable geology, grasp tunnel geology concrete condition
Under the premise of, use can be integrated, saves cost to a certain extent.Grid can be classified as structure support one kind with bracing members,
The former is only used in combination with concrete, its support action of competence exertion, and cannot play carrying effect immediately.And the latter can be with
Immediately, carrying effect is independently played.
For current engineering reality, the tunneling technique in China gradually develops, and the difficulty of tunnel construction gradually increases, anchor
Bar is during construction, due to being influenced by construction personnel, construction machinery, field engineering condition, most of anchor pole
Can all occur the unfavorable factors such as offset, dislocation after mounting, when especially carrying out carrying out combined supporting with shield duct piece, these are not
Sharp factor will influence whether entirely to construct.
A kind of combined retaining structure for concrete pipe sheet anchor pole deviation of the invention integrates many merits, has
The advantages of following several respects：High capacity, easy for construction, speed of application is fast, good economical benefit, and supporting effect is good, shortens working hour,
Cost is reduced, for there are the anchor poles of deviation also directly can just construct in work progress.
