Description
Technical field
The utility model discloses in a kind of steel bushing cross-brace mounting structure applied at shield tunneling hole, belong to
Subway shield tunnel construction technical field.
Background technique
Subway is when using shield construction, in order to ensure shield machine is into hole or while appearing avoids because originating (or arrival)
End water burst and caused by collapse, generally into portal steel loop, portal steel loop and station main body are arranged at hole or the portal appeared
Close structure links together, and is conducive to the node waterproof of station (or foundation pit) and section in this way, prevents because of originals such as unfavorable geologies
Because generating Sand phenomenon, ground is caused to collapse.
When portal steel loop is installed at the scene, in order to make steel loop accurate positioning, easy for installation, need reasonably to install
Easy to disassemble or counter-force support construction guarantees that portal steel loop is stablized.
Utility model content
The purpose of this utility model is that devising a kind of steel bushing mounting structure, guarantee that steel loop positioning is quasi- with this configuration
Really, easy for installation.
To achieve the above object, the technical solution adopted in the utility model is a kind of applied on portal steel loop steel bushing
Mounting structure, the structure include cross-brace 1, bracket 2, steel bushing 3, feed opening 4, bolt hole 5, lifting lug 6 and counter-force hydraulic cylinder
7。
Station main structure is connect with cross-brace 1, and cross-brace 1 is connect with bracket 2；Steel bushing 3 is mounted on bracket 2
On；Feed opening 4 and lifting lug 6 are arranged in the side of steel bushing 3, the setting of counter-force hydraulic cylinder 7 AT STATION main structure and steel bushing 3 it
Between.Cross-brace 1 is formed by reinforcement welding.
Bolt hole 5 is laid along the section direction of steel bushing 3.
The pedestal of counter-force hydraulic cylinder 7 is fixed on steel bushing 3, and the telescopic rod and station main structure of counter-force hydraulic cylinder 7 connect
It connects.
Detailed description of the invention
Fig. 1 is applied to the mounting structure schematic diagram on portal steel loop steel bushing.
Specific embodiment
As shown in Figure 1, a kind of mounting structure applied on portal steel loop steel bushing, which includes cross-brace 1, support
Frame 2, steel bushing 3, feed opening 4, bolt hole 5, lifting lug 6 and counter-force hydraulic cylinder 7.
Station main structure is connect with cross-brace 1, and cross-brace 1 is connect with bracket 2；Steel bushing 3 is mounted on bracket 2
On；Feed opening 4 and lifting lug 6 are arranged in the side of steel bushing 3, the setting of counter-force hydraulic cylinder 7 AT STATION main structure and steel bushing 3 it
Between.Cross-brace 1 is formed by reinforcement welding.
Bolt hole 5 is laid along the section direction of steel bushing 3.
The pedestal of counter-force hydraulic cylinder 7 is fixed on steel bushing 3, and the telescopic rod and station main structure of counter-force hydraulic cylinder 7 connect
It connects.
Embodiment
(1) before starting that steel bushing is installed, well head shield body center line, that is, steel bushing are determined in foundation pit first
Installation site, make the steel bushing for hanging oneself to get off from ground make every effort to disposably be put into position, without moving left and right again.
(2) lower semisection for successively hanging lower first segment to Section of four steel bushing, makes the center of steel bushing and has been determined in advance
Well head shield body center line is overlapped.
(3) upper semisection for successively hanging lower first segment to Section of four steel bushing after steel bushing upper semi-circle installs, needs to carry out
The adjustment of hold-down bolt.
(4) transition circumferential direction steel plate and portal firm welding.
Steel bushing realizes connection by setting transition circumferential direction plate and portal steel loop.It is installed first when installing first segment sleeve
Transition rings and portal steel plate after repetition measurement central axis, are then passed through welding again after entire cylinder completes connection by transition ring flat-plate
It is connected firmly, weld seam encloses inside spot welding along transition rings one, and pastes sealing rod in inside.Such as occur transition rings and portal steel plate some
There is larger gap in place, need to fill steel plate in these gaps and be connected firmly, must block as much as possible gap.
(5) position and check connection, it is ensured that securely
Check each portion junction, the place for being coupled installation to everywhere is tested, it is ensured that its integrity connected, especially
It is the inspection being coupled between upper lower half circle and section and section part for steel bushing, also checks transition connecting plate and portal ring flat-plate
Between welding situation, see with the presence or absence of disengage the phenomenon that, discovery have hidden danger, to handle in time.
After the positioning of (6) four section cylinders, carry out that portal is secondary abolishes, after abolishing after portal thoroughly crushes, by rear portion end
Upper ring beam is hung down, to being bolted after the flange of good steel bushing, center-line joint steel bar welded seal after 16mm.
(7) the anti-carrier head device of shield machine in steel bushing
Shield machine occurs after entering in steel bushing because center of gravity is detached from main structure, and without support inside steel bushing
In the case where cause shield machine plant head the case where generation.And head is once planted, the rotation of cutterhead can cause biggish injury to cylinder,
So must be supported to shield body before center of gravity is without departing from structure.Supporting form multiplicity, after having comprehensively considered various factors,
Supporting form is used as in such a way that sleeve bottom pours one layer of C20 concrete, after steel bushing is installed, portal is complete before cutting
At.
The selection multiplicity of the chamber in-vivo medium of steel bushing 3, has and adds the selection such as water, gaza.But water is added to be easy pressure release, gaza pushes away
Power torque is excessive.
The setting of counter-force hydraulic cylinder 7 is stablized to guarantee the installation of steel bushing 3 and adjust.
