The underground nuclear power station of the present embodiment adopts two heap CUP600 to arrange, adopts drop shaft method to organize underground power house cavern excavation, from top work plane tissue, excavates, and slips slag slag tap from bottom work plane tissue by the well of slagging tap.Construction passage that can be minimum by drop shaft method organizing construction meets construction requirement, therefore each factory building cavern of the utility model only need arrange two-layer hole system of top layer and bottom: bottom props up hole can make full use of the existing permanent passage first main access tunnel 9 of main access tunnel 8, second and the 3rd main access tunnel 10 fork layouts; Top layer props up hole and can arrange by first main hole 41, second main hole 31 and the 3rd main hole 32 forks, and this is conducive to reduce the construction works amount in a hole.Bottom props up hole system and top layer and props up hole system and all keep suitable spacing with cavern around, to guarantee cavity group stability and safety.The hole of excavation is few, mileage is short, and investment just economizes, and props up that hole is few, mileage is short, spacing is suitable simultaneously, and the safety of whole engineering also can be better; Because two heap CUP600 underground nuclear power stations layout nuclear island factory building cavity groups have been accomplished modularized design, therefore the design and construction of the utility model structure can be accomplished modularization.Specifically be implemented as follows:
Due to the first main access tunnel 8 as permanent passage, the second main access tunnel 9 and the 3rd main access tunnel 10 and can be as be arranged in ± 0m of main steam passage 11 elevation of passage, at the bottom of Er Ge factory building cavern, elevation all has the larger discrepancy in elevation therewith: such as 1 end of reactor building cavern elevation is-9.0m, at the bottom of combination cavern, elevation is-12.5m, 2 end of electrical building cavern elevation is-12.5m, at the bottom of release cavern, elevation is+20.0m, so all can not directly utilize the first main access tunnel 8 as permanent passage on plane and facade, the second main access tunnel 9 and the 3rd main access tunnel 10 and can be as the main steam passage 11 of passage.For meeting the requirement of slagging tap of the excavation of bottom, each cavern, need to arrange bottom, bottom Zhi Dongzhige cavern; Simultaneously, for reducing massif, hollow out rate, reduce to affect the stable unfavorable factor in each cavern, and reduce bottom and prop up hole engineering cost, do not establish separately bottom master and prop up hole, but make full use of permanent passage, by the first main access tunnel 9 of main access tunnel 8, second and the 3rd main access tunnel 10 forks, draw and arrange that each bottom props up hole 21,22,23,24 and 25 and passes to elevation place at the bottom of each cavern.Wherein, because differing, the end elevation of release cavern 7 and main access tunnel elevation reach 20m, be difficult to arrange that the bottom of suitable longitudinal gradient props up hole, therefore prop up the first level in hole 25 with release hole bottom, pass to 7 axis places, release cavern, then by establishing, slip slag vertical shaft and be connected with 7 bottoms, release cavern in work progress.Each bottom props up hole longitudinal gradient and is all less than 12% above, meets trackless movement requirement.
Because each factory building cavern crest level is higher and height differs: such as reactor building cavern 1 crest level is+78.0m, combination cavern crest level is+57.85m, electrical building cavern 2 crest levels are+46.8m, release cavern crest level is+62.0m, so all can not utilize the permanent passage first main access tunnel 9 of main access tunnel 8, second and the 3rd main access tunnel 10 on plane and facade, the elevation of device channels 12 is+20.0m in addition, the discrepancy in elevation of Yu Ge cavern is excessive, therefore need to separately establish top layer, props up hole to each factory building crown arch springing or crown headwall.Because reactor building cavern 1 crown is the highest, on facade and in plane, all cannot share construction passage with other caverns, therefore establish separately first main hole 41, then fork is drawn the first reactor building cavern top layer and is propped up hole 42 and the second reactor building cavern top layer and prop up hole 43 and pass to respectively the crown arch springing place that corresponding reactor building cavern 1 elevation is+65.0m.Though combination cavern, electrical building cavern 2, release cavern 7 crest levels differences, but the discrepancy in elevation on facade is less, Ci San class cavern shares second main hole 31, the 3rd main hole 32, by two masters, prop up hole fork and establish the first combination cavern end top layer and prop up hole 33, electrical building top layer and prop up that hole 35 is propped up in hole 34, combination stage casing, cavern top layer, the first release hole top layer props up hole 36 and the second release hole top layer props up hole 37, above these top layers prop up hole and all pass to each arch springing elevation place, cavern.Wherein, from second main hole 31 and the 3rd main hole 32, pass to the combination cavern crown headwall that elevation is+48.0m; From the first combination cavern end top layer, propping up hole 33 fork establishes electrical building top layer and props up hole 34 and pass to respectively the crown headwall that electrical building cavern 2 elevations are+37.0m; From the 3rd main hole 32 forks, establishing respectively the first release hole top layer props up hole 36 and the second release hole top layer and props up hole 37 and pass to the crown arch springing that Liang Ge release cavern 7 elevations are+52.0m.Due to combination, cavern comprises four factory buildings, axis is longer, therefore arranged that especially second main hole 31, the 3rd main hole 32, the first combination end, cavern top layer prop up hole 33, combination stage casing, cavern top layer and prop up hole 35 and the first combination end, cavern bottom and prop up hole 22, second and combine end, cavern bottom and prop up hole 24, to increase work plane, the balance duration, and be beneficial to crown quick supporting to guarantee crown construction period stability and safety.Wherein each top layer props up hole longitudinal gradient and is all less than 12%, meets trackless movement requirement.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these changes and modification interior.
The content not being described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
