Including work well major structure headwall, work well envelope, in advance the shield construct portal ring beam and shield and construct the section of jurisdiction, it is as an organic whole that major structure headwall and shield in advance construct the consolidation of portal ring beam. The shield constructs the portal ring beam outside and sets up the shield and construct the portal collar tie beam in advance, and it is as an organic whole that this shield constructs that portal collar tie beam passes through the connecting elements and the shield constructs the portal ring beam in advance, the shield constructs section of jurisdiction fixed connection, and the portal collar tie beam constructs between the portal ring beam with shield in advance, portal collar tie beam and shield structure section of jurisdiction are provided with the stagnant water component.
Description
Technical field
The utility model relates to shield tunnel, is particularly a kind ofly applicable to the tunnel shielding portal collar tie beam structure of shield end without reinforcing body.
Background technology
Tunnel shielding portal collar tie beam is shield machine working shaft headwall and shield tunnel joining place structure, and shield duct piece is connected an entirety by Main Function with shield structure headwall, and plays the effect of interface sealing.
Shield structure start safely with arrive after, remove negative endless tube sheet, and then construction portal collar tie beam, traditional portal collar tie beam performs inside active well agent structure termination, need before portal collar tie beam performs to cut a part of section of jurisdiction and draw a collar tie beam scope reinforcing body of digging a hole, therefore, only have active well end soil body self-stability good, and need take as in the situations such as a few endless tube sheet of portal scope dorsal part secondary reinforcement grouting and reinforcing, the safety of guarantee portal collar tie beam performs.If under, high water head condition large at complex geologic conditions, active well buried depth, and termination consolidation effect is difficult to ensure; Or take closed origin and arrive new technology (reinforcing without the need to termination), traditionally portal collar tie beam position performs, and there is great risk, may cause and leak, leak sand and even the engineering accident such as termination caves in, foundation pit deformation.
Utility model content
Technical problem to be solved in the utility model is to provide and is a kind ofly applicable to the tunnel shielding portal collar tie beam structure of shield end without reinforcing body, effectively to avoid cutting portal scope section of jurisdiction construction risk, save shield end and reinforce expense, and be convenient to performing of portal collar tie beam simultaneously.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Of the present utility modelly a kind ofly be applicable to the tunnel shielding portal collar tie beam structure of shield end without reinforcing body, comprise active well agent structure headwall, active well space enclosing structure, tunnel shielding portal ring beam and shield duct piece in advance, agent structure headwall and in advance tunnel shielding portal ring beam consolidation are integrated, it is characterized in that: the described ring beam of tunnel shielding portal in advance arranged outside tunnel shielding portal collar tie beam, this tunnel shielding portal collar tie beam is by connecting elements and tunnel shielding portal ring beam in advance, shield duct piece is connected to one, portal collar tie beam and in advance between tunnel shielding portal ring beam, portal collar tie beam and shield duct piece are provided with waterstop member.
The beneficial effects of the utility model are, the problem of section of jurisdiction is cut before efficiently solving the construction of portal collar tie beam, simultaneously because tunnel shielding portal circle beam setting is outside active well agent structure headwall, without the need to drawing the grouting and reinforcing body inside except active well agent structure headwall, therefore can effectively avoid causing portal Sand risk, even and if termination geological conditions is poor, in Endless reinforcing situation, also can perform tunnel shielding portal collar tie beam safely; Be integrally connected between tunnel shielding portal collar tie beam and active well agent structure headwall, shield duct piece, good water-proof effect, structure construction is simple, does not affect other specialty, has wide promotion prospect.
Accompanying drawing explanation
This manual comprises following two width accompanying drawings:
To be that the utility model is a kind of be applicable to the tunnel shielding portal collar tie beam structure of shield end without reinforcing body to Fig. 1;
Fig. 2 is that a kind of shield end that is applicable to of the utility model is without tunnel shielding portal collar tie beam in the tunnel shielding portal collar tie beam structure of reinforcing body and shield duct piece, in advance tunnel shielding portal ring beam connected mode schematic diagram;
Component shown in figure and corresponding mark: tunnel shielding portal collar tie beam 1, implantation section of jurisdiction connecting reinforcement 11, hole connecting bolt 12, first water expandable waterstop 13, second water expandable waterstop 14; Active well agent structure headwall 2; Active well space enclosing structure 3; Tunnel shielding portal ring beam 4, pre-buried connecting reinforcement 41, hole annular pre-embedded steel slab 42 in advance; Shield duct piece 5; Grouting and reinforcing body 6.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See figures.1.and.2, of the present utility modelly a kind ofly be applicable to the tunnel shielding portal collar tie beam structure of shield end without reinforcing body, comprise active well agent structure headwall 2, active well space enclosing structure 3, in advance tunnel shielding portal ring beam 4 and shield duct piece 5, agent structure headwall 2 and in advance tunnel shielding portal ring beam 4 consolidation are integrated.The described ring beam 4 of tunnel shielding portal in advance arranged outside tunnel shielding portal collar tie beam 1, this tunnel shielding portal collar tie beam 1 is by connecting elements and tunnel shielding portal ring beam 4, shield duct piece 5 are connected to one in advance, portal collar tie beam 1 and in advance between tunnel shielding portal ring beam 4, portal collar tie beam 1 is provided with waterstop member with shield duct piece 5, prevents shield duct piece 5 dorsal part water to portal seepage.。Be integrally connected between tunnel shielding portal collar tie beam 1 and active well agent structure headwall 2, shield duct piece 5, good water-proof effect, structure construction is simple, does not affect other specialty, has wide promotion prospect.Because tunnel shielding portal collar tie beam 1 is arranged on outside active well agent structure headwall 2, without the need to drawing the grouting and reinforcing body 6 inside except active well agent structure headwall 2, therefore can effectively avoid causing portal Sand risk, even and if termination geological conditions is poor, in Endless reinforcing situation, also can perform tunnel shielding portal collar tie beam 1 safely, before efficiently solving the construction of portal collar tie beam, cut the problem of section of jurisdiction.
With reference to Fig. 2, described connecting elements comprises hoop spaced hole connecting bolt 12, and hole connecting bolt 12 is fixedly connected with the implantation section of jurisdiction connecting reinforcement 11 in portal collar tie beam 1, and the other end and shield duct piece 5 removably connect.Described connecting elements comprises the hole annular pre-embedded steel slab 42 be arranged in tunnel shielding portal ring beam 4 outer end wall in advance, this hole annular pre-embedded steel slab 42 with in the pre-buried connecting reinforcement 41 in tunnel shielding portal ring beam 4 in advance and portal collar tie beam 1 arrangement of reinforcement be fixedly connected with.
