Example of the constructing tunnel provided by the present application with Moveable support structure in practical applications.
The rivers Luo Zha level-one power station is located at the domestic Lancang River right bank level-one tributary rivers the Luo Zha downstream in Yunnan Province Yun County, away from cloud
County county town 36km, to generate electricity as single task role, installed capacity is 2 × 15MW, 13,960,000 m of total reservoir storage3, project scale or rank of project III
Deng.
Diversion tunnel is to have pressure circular holes, barrel segment length 895（0+003.65~0+895m）, play bottom of slope elevation
992.725m, it is to draw 0+013.650 that diversion tunnel, which plays slope point pile No., draw 0+0748.261 section slope ratios of 0+003.650~draw for i=
2.547%, it is i=5.95% to draw 0+818.251 sections of Duan Po ratios of 0+748.261~draw；Plane is equipped with 4 turnaround sections, and II class surrounding rock is opened
Cross section diameter 7.39m is dug, III class surrounding rock excavated section is diameter 7.35m, the IV a diameter of 7.95m of class surrounding rock excavated section, is used
C25W6 is lining cutting concrete and element spray concrete, and C15 is to smear bottom concrete.Wherein draw 0+950.775 sections of 0+891.528~draw using 16mm~
28mmQ345R plate-steel liners, pressure pipeline are made of supervisor, bifurcated pipe and branch pipe.
Construction Difficulties：(1) diversion tunnel overall length 895m, it is II, III, IV class surrounding rock to be related to surrounding rock category, wherein needing steel
Reinforced concrete liner sections total length is 155m, accounts for the 17.4% of overall length, cavern is integrally rounded, and hole wall surface is coarse, is unfavorable for
The installation of design of coupler scaffold.(2), since various aspects unfavorable factor early period influences, there is duration lag in diversion tunnel, according to most
Newly built construction node plan, diversion tunnel concrete lining in August in 2017 5 days, December 19 end of day.Penstock is installed
Start from August in 2017 15 days, November 17 end of day.Cause the current part duration to conflict, is timely completed engineering project
As the difficult point solved is badly in need of, how not only to ensure that hole inside lining was carried out at the same time with penstock transport, installation, but also saves significantly
The about duration reduces cost, is this scheme main problem to be solved.
To solve the above-mentioned problems, using constructing tunnel provided by the present application Moveable support structure, specifically, can
Mobile steel bracket uses the mechanical property common I-steel 1.5t of moderate 16 type, adjustable jacking 50, self-locking trundle 8 to prevent
Protecting wire net 11m2, upper surface is laid with plank or bamboo chip plate 24m2.It selects steel part that must not have crackle, stomata, should not have shrinkage porosite, sand holes, pour
Riser remnants fash, burr, oxide skin etc..I-shaped steel surface should make antirust treatment, while be carried out with related mixed paint on surface
It brushes.The rectangular inverted U of steel bracket every, both sides steelframe high 5m, wide 4.15m, right angle joint are welded with I-shaped bracing members and preapre for an unfavorable turn of events
Self-locking wheel is welded in shape, both sides steelframe bottom, totally 5 row.Spacing 1.5m is arranged, connection steel is welded between row, connection steel both ends are welded respectively
It is connected on both sides longitudinal direction steelframe central point, away from ground 2.4m, it is 3 equally divided positions for often arranging the horizontal steel of holder that top, which connects steel pad,.Steel
After the completion of frame overall structure, plank or bamboo chip plate 24m are laid with and fix at top2, welded respectively in steel bracket both sides and top
Top, the top spacing 1.25m of both sides 3, often arranges cradle top and welds 4 tops, spacing 0.83m.Steel bracket march into the arena after in side
Open protection network 11m in face2。
The constructing tunnel Moveable support structure made of above-mentioned specification, uses in the seepage tunnel of the rivers Luo Zha
When, diversion tunnel diameter is averagely about 7.55m, concrete lining thickness 39cm, Moveable support high 5m, wide 4.15m, length
6m.Roping concrete tank overall height 3.78m, wide 2.48m, holder do not influence concrete tank passage.Outside penstock manifold portion
Diameter 3.816m, stiffening ring extend outwardly 0.2m, and the high 0.4m of trolley, overall length 4.616m, branch pipe completely can be under holder by reaching
To installation site.Penstock is responsible for a diameter of 6.036m of water-ring, the high 0.4m of trolley, and supervisor's semicircle is with trolley track height
3.418m can be grouped with semicircular arc-shaped by carrying out assembled welding after below holder, reaching installation designated position.Bifurcated pipe tube coupling is most
Major diameter is 5.548m, without stiffening ring, because diameter is less than predominant tube diameter so can equally grouping be utilized to pass through by method
Assembled welding and installation are carried out after below holder.All tube couplings utilize hoist engine and trolley by steel pipe transmission to installation site.
As it can be seen that constructing tunnel provided by the present application Moveable support structure when using, primary welding is built i.e. available
It in multistage lining construction, can be recycled for multiple times, and penstock transport installation can be made to be carried out at the same time, greatly shorten the work
It the journey duration, does not restrict mutually.Meanwhile there are adequate space 5m × 4.15m for steel bracket lower part, can meet penstock completely
Space needed for transport, while can be transported for concrete horizontal and channel is provided.Removable steel bracket can in lining construction section and
Intersegmental movement after once building welding, need not remove repeatedly, can start the portion by moving integrally to predetermined construction site
Give work.The welding of building of removable steel bracket needs 3 days；It only need to once build, it can be achieved that recycling, overall movement uses
The characteristics of the loss of material is greatly reduced compared with scaffold, improve construction efficiency and economic benefit.
In short, constructing tunnel provided by the present application Moveable support structure, simple and reasonable, allow cavern's lining cutting
It is carried out at the same time with penstock transport installation, solves duration collision problem, greatly shorten the part duration of a project；It builds
It is formed after welding and stablizes entirety, many places construction section can be moved to, need not be built repeatedly, and can realized to follow and badly repeatedly utilize,
Peace is torn open simply, is saved resource, construction cost is favorably saved, to create economic benefit.
