Description
Technical field
The utility model is related to construction engineering technical field, specifically a kind of platform quickly handled for Tunnel Landslide
Frame.
Background technology
In recent years, in terms of constructing tunnel, arch and face cave in accident happen occasionally, and especially complicated geology is soft
Weak country rock location, although taking advance support measure, is influenceed by geology, design and construction many factors, and landslide is outstanding
It is that middle-size and small-size landslide is almost difficult to avoid that.The method for handling middle-size and small-size landslide at present is a lot, mainly have pipe shed method, slip casting method,
Combination of self-feeding anchor pile method and several method etc., but be all difficult to meet safe and efficient require.Sent out in face and vault
The most frequently used technology is during raw medium and small landslide：Collapse the stable landslide body of the basicly stable rear gunite concrete in cave, grouting reinforcement landslide body,
By the use of collapsing body slag or support is set up as job platform, the chamber that collapses on platform in the stable certain altitude of gunite concrete, from
The chamber that collapses distally starts to install steel arch-shelf, and sets Shed-pipe Advanced Support, and bow member sets dividing plate gunite concrete, drawn near by Pin behind
Closing, during according to cave height is collapsed and delivery pump pipe is buried in aperture, all support, pump are set after closing on the outside of supporting in the early stage
Certain thickness concrete formation consolidation circle is sent, then the cave that is not filled by more than consolidation circle collapsing is partially filled with the sand of adding coal ash
Slurry, dry husky or other light materials, form cushion, and the technology preferably resolves processing and collapsed difficulty present in work of spreading manuer in holes
Greatly, the problems such as big quality of coming to nothing behind is difficult to ensure that.But process cycle is longer, there is possibility of caving in again in work progress,
There is certain security risk.
Small sump remedy technology has that process is more, the cycle is longer, cost is larger, risk is higher etc. and asked in conventional tunnel
Topic.

Formula impacts each plate to watching close face.The gunite concrete formation preliminary bracing on the outside of plate, is pumped mixed using short pump line
After concrete final set, light-duty mortar is irrigated using long pump line to vault above 2m for solidifying soil perfusion.Concrete strength reaches 10Mpa
During the above, stand is removed, spreading both sides bow member completes whole preliminary bracings.
（1）Step 1 stand is processed
Place of safety processing supporting stand after landslide, stand is by portal frame system, steel arch-shelf and longitudinally connected reinforcing bar, vault
Embedded steel board and Auxiliary support positioner composition.Supporting platform is determined according to landslide body upper space size and landslide area's ring scope
The height and width of frame portal frame system, crossbeam, column, the diagonal brace of door frame etc. use I-steel weld assembly（I-shaped steel pattern number according to
Landslide height, door frame width and height etc. are comprehensive to be determined）Door frame periphery is according to the bow member model and spacing after former design or change
Arrangement, entirety is connected between bow member and door frame in succession using steel welding.Surpass at the top of bow member in landslide area's ring scope per side
Go out 1m arrangement above embedded steel boards, the closed inserting plate hole of steel plate solid matter, steel are being used on wing plate on the outside of every Pin bow members in the range of the chamber that collapses
Plate is passed through from hole, embedded steel board 30~40cm of width, 5~10mm of thickness of slab.In the vertically arranged small-sized machine of door frame column bottom
Jack is used for the vertical positioning of door frame.
（2）Step 2 stand is in place and locks
Using excavator by body top surface moderately smooth compacting of caving in, placing bulk steel plate in stand column Position Approximate is used for
Increase the supporting force on stand basis.Stand is moved integrally to bottom of chamber portion of collapsing using excavator, manually being aided in stand bottom will
Stand is substantially in place, and column is placed at the top of supporting steel plate.Both sides symmetry operation jack, makes stand and the big densification of tunnel palisades
Patch, locks jack.
（3）Step 3 plate is in place
Promote embedded steel board and face country rock to hold out against piecewise using excavator, have compared with being welded with the sealing of small steel plate at big gap,
And fill in the materials such as Anchor Agent, it is ensured that will not a large amount of spillage.Ring welded reinforcement is linked to be entirety on the inside of neighbouring face embedded steel board.
（4）Step 4 sets lock pin anchor tube（Bar）
4 lock pin anchor tubes are set at steel arch-shelf footing above 30cm（Bar）, it is welded into using L-type steel muscle and steel arch-shelf whole
Body, and slip casting locking.
（5）Step 5 buries delivery pump pipe
In landslide area extreme higher position, 2 delivery pump pipes, a length 3~4 are buried for support perforate using gantry beam
Rice, another extends at the 20~30cm of top of chamber that collapses.
（6）Step 6 gunite concrete
According to the thickness of design or design for change in bow member scope gunite concrete, to reduce injection springback capacity, it can insert
One layer of reinforced mesh of welding on the outside of plate.
（7）Step 7 is collapsed chamber pump concrete
Connect short delivery pump pipe pumping more than C20 concrete, concrete height to more than vault at least 2m.In casting process
Bow member, the deformation of stand are observed at any time, and graded is poured when amount of concrete is larger.
（8）Step 8 pressure injection light material
After the pump concrete final set phase, using long delivery pump pipe to collapse intracavitary pumping or slip casting machine irrigate sand+flyash+
The light mortar of cement, can irrigate the lightweight materials such as lightweight balloon concrete as cushion when having ready conditions.
（9）Step 9 removes stand
Intracavitary of collapsing concrete strength is reached after more than 10Mpa, removes combination supporting stand, stand is moved to outside hole or torn open
Solution.
（10）Spreading abutment wall bow member, suspended net shotcrete
Cleaning landslide body, spreading abutment wall bow member sets system anchor bolt, hangs bar-mat reinforcement, gunite concrete forms complete
Preliminary bracing.
（11）Monitoring measurement and excavation driving
In work progress and after the completion of persistently carry out the monitoring of Vault settlement and perimeter convergence, will according to design and specification
Ask, recover the excavation driving of face.
