Be labeled as in figure: damp-proofing wall 1, drain hole 2, gutter 3, bottom surface 4, constructional column 5, sidewall 6, anchor pole 7, drain hole 8, ceiling connector 9, ventilation gap 10, overhead lighting system 11, ceiling 12, end face 13, impervious barrier 14, cable rack 15, decoration publicity structure 16.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Powerhouse of hydropower station cavern fitting structure comprises the cavern with end face 13, bottom surface 4 and twice sidewall 6; Powerhouse of hydropower station cavern fitting structure comprises ceiling 12 and twice damp-proofing wall 1; Twice damp-proofing wall 1 is arranged near twice sidewall 6 respectively, damp-proofing wall 1 inner surface is coated with and is brushed with impervious barrier 14, be arranged at intervals with some constructional columns 5 between damp-proofing wall 1 and sidewall 6; Region on bottom surface 4 between damp-proofing wall 1 and sidewall 6 is provided with gutter 3, and constructional column 5 bottom is provided with drain hole 2, and gutter 3 is communicated with drain hole 2 and forms drainage channel; Ceiling 12 is made up of galvanized steel corrugated sheet, and ceiling 12 and end face 13 form fit, ceiling 12 is arranged at above damp-proofing wall 1, and ceiling 12 both sides are connected with damp-proofing wall 1 respectively, and ceiling 12 edge is between damp-proofing wall 1 and sidewall 6.
In the utility model the construction method such as the building of constructional column 5 and damp-proofing wall 1, connection and prior art construction method consistent.
Powerhouse of hydropower station cavern fitting structure can carry out secondary decoration at damp-proofing wall 1 inner surface after having constructed again, makes cavern more attractive in appearance; And overhead lighting system 11 can be set on ceiling 12, damp-proofing wall 1 arranges cable rack 15 and decoration publicity structure 16 etc., and make cavern's function more complete, decoration publicity structure 16 can be air brushing, lamp box, LED television etc.
The utility model is invested lower than the full liner structure of tradition " steel-concrete ", strong adaptability, and the construction period is short, and it is little that structure takies cavern's traffic space, safeguards, replaces conveniently in running.The ceiling 12 that galvanized steel corrugated sheet is made can according to cavern's top surface shape adjustment radian, and ceiling 12 is without beam without purlin, and not lower outstanding component, takies crown space few, have certain space advantage.Constructional column 5 amount of building is few, and construction takes up room little, can many holes section construct simultaneously.It is fast that damp-proofing wall 1 builds speed by laying bricks or stones, do not take the straight line duration, many holes section can construct simultaneously, do not affect traffic in hole.The processing of ceiling 12 scene, easy to make, strong adaptability; Installation in hole, adjustment is transported to after prefabricated outside cavern, easy for installation, fast, the reduction of erection time greatly.The operations such as ceiling 12 is installed, impervious barrier 14 is brushed, the secondary decoration of damp-proofing wall 1, overhead lighting system 11 are installed, cable rack 15 installation inside damp-proofing wall 1 can a point hole section be carried out simultaneously, and construction interference is little mutually, can reduction of erection time greatly.
Adopt cavern's draining of the utility model structure finishing convenient, the drainage pattern of cavern is: bottom surface 4 infiltration is fallen on ceiling 12, along ceiling 12 from flowing to ceiling 12 edge, then falling in gutter 3, being discharged to outside hole by gutter 3.Sidewall 6 seeps water and converges side wall 6 by drain hole 8 and flow in gutter 3, is also discharged to outside hole by gutter 3.Arranging drain hole 2 is in order to avoid constructional column 5 stops current.
The connected mode of ceiling 12 and damp-proofing wall 1 is by multiple, and Fig. 2 is the connected mode of a kind of ceiling 12 and damp-proofing wall 1.In Fig. 2, powerhouse of hydropower station cavern fitting structure comprises ceiling connector 9, ceiling connector 9 comprises and setting gradually and the base plate 9-1 connected, middle connecting plate 9-2 and top board 9-3, and base plate 9-1 is bolted in damp-proofing wall 1 top, and top board 9-3 is obliquely installed and is connected with ceiling 12 by bolt.Ceiling connector 9 can be made up of " H " shaped steel, specifically makes the one side of H profile steel be formed slopely top board 9-3, and top board 9-3 angle of inclination should adapt to the radian of ceiling 12.Ceiling connector 9 also can be made up of channel-section steel, specifically makes one of channel-section steel laterally inclined formation top board 9-3.H profile steel model selects 125x125 to 250x250 usually, and channel-section steel model selects 14b to 20b usually.The bolt connecting damp-proofing wall 1 is generally expansion bolt.
For the ease of making ceiling 12 edge between damp-proofing wall 1 and sidewall 6, constructional column top is provided with groove 18, and ceiling 12 edge is positioned at groove 18.Groove 18 groove depth considers concreting and installation, mismachining tolerance, comparatively theory calculate degree of depth basis should increase 5.0cm.
Earthquake easily sends out region, and in order to improve cavern's shock resistance, damp-proofing wall 1, constructional column 5 are connected by anchor pole 7 with sidewall 6.Namely anchor pole 7 inserts sidewall 6 through damp-proofing wall 1 and constructional column 5.
Cavern head, ceiling 12 is difficult to be an entirety, and therefore the utility model ceiling 12 is spliced by some ceiling floors arranged along cavern's length direction.The length of ceiling floor should consider seam number of channels, cavern's trend etc. between ceiling weight, segmentation, and be usually chosen for 5.0 to 8.0m, turning, cavern ceiling floor length should suitably reduce.In order to leakproof, between adjacent top refractory slab, adopt mulseal to connecting and Anti-seeping technology.
Under guarantee installing space prerequisite, ceiling 12 radian can be adjusted to laminating end face 13 as far as possible, both make use of space, cavern to greatest extent without crossing the cavern that wind requires, it also avoid indivedual infiltration section and to drip the larger situation of potential energy.There is factory's dam contact access tunnel adjustable ceiling 12 radian of air-conditioning requirement, make there is ventilation gap 10 between ceiling 12 and end face 13, ensured wind area.
In order to avoid each steel component parts gets rusty, and avoid ceiling to seep water, ceiling 12, ceiling connector 9 and the bolt that is connected with ceiling connector 9 are all through antirust treatment; Ceiling 12 and ceiling connector 9 junction are through encapsulating Seal treatment.
The utility model construction method is as follows:
Outside cavern, metal construction processing place processes ceiling floor according to cavern's characteristic size and functional requirement galvanized steel corrugated sheet.Ceiling floor Machining comprises illumination and waits the boring of suspender basis and preservative treatment; Installing hole is stamped in ceiling floor both sides of the edge.According to after ceiling floor radian determination H profile steel or channel-section steel angle of bend, H profile steel or channel-section steel are made ceiling connector 9.The bolt after preservative treatment is so then utilized to connect ceiling floor and ceiling connector 9.
Use small-sized forklift to coordinate manpower to transport the ceiling floor that machines in hole, carry out adjusting rear utilization and process hole on ceiling connector 9 in advance ceiling floor is fixed on sidewall 6 top by expansion bolt.
Each ceiling floor seam crossing all needs to adopt the materials such as mulseal to carry out connecting-Anti-seeping technology.
Finally brushing impervious barrier 14 on damp-proofing wall 1 inner surface, and the Seal treatment such as sealing are carried out to each bolt of ceiling floor and boring, prevent outside crag infiltration corrosion steel work.
Finally, every secondary decoration work is carried out.
Cavern's scale of factory's dam contact access tunnel is less, fail to grow up in hole, and Stability of Excavation Surrounding solves by flexible support mode.The utility model is specially adapted to underground power station factory dam contact access tunnel.
