Description

The installation method of condenser

Technical field

The present invention relates to the turbine architecture construction technology in the nuclear power plant etc., particularly move into the condenser installation method of condenser being installed and being improved operating efficiency economically.

Background technology

Condenser installation method before is described below with reference to Fig. 7 to Figure 12 in the turbine buildings of nuclear power plant.

Fig. 7 and Fig. 8 are the skiagraphs along turbine buildings different directions.Fig. 9, Figure 10 and Figure 12 are the figure of expression erection sequence.Figure 11 is the expression condenser and transports the figure that uses strengthening part.

Fig. 7 and turbine buildings 1 shown in Figure 8 are so-called semi-underground type turbine buildingss, and the running ground 1a of turbine generators flushes with ground surface.Before, with the construction process of this turbine buildings 1, the installation method of condenser is divided into two kinds substantially.

The installation method of the 1st kind of condenser is at the ground construction of the running ground 1a that has carried out turbine generators and after having constructed turbine generators basis platform 9, carries out the installation work of condenser.This method has two kinds of methods again, a kind of be with condenser as dividing body, with the interim crane that is provided with, be the condenser dividing body opening portion of above-below direction from low pressure turbine 3 mounting portions of turbine generators basis platform 9, hang in the installation site.Other method is that interim opening (being also referred to as back construction portion, hereinafter referred to as interim opening) is set on the outer wall of turbine buildings 1, and condenser is drawn in platform 9 inner precalculated positions, turbine generators basis from outdoor excavation portion 10 along transverse direction.

The method that the former hangs in, its order after turbine generators basis platform 9 is finished (S901), are cut apart condenser body 4 and are moved into (S902) as shown in Figure 9, assemble (S903).Then, remove transporting of condenser body 4 and use reinforcement (S904), the installation of most of parts finishes, behind 4 pairs of centers of condenser body, making steam become the cooling tube of condensate water (to scheme not show, hereinafter referred to as " cooling tube ") move into from the interim opening 8 that is located on turbine buildings 1 outer wall, be inserted into the precalculated position of condenser body 4, (S905) is installed.Then, restore to import the interim opening (S906) of usefulness, carry out turbine buildings outer wall waterproofing work (S907), carry out the place construction (S908) of backfill etc.

The latter moves the method for moving into installation with transverse direction, its order as shown in figure 10, the condenser body 4 that is divided into several parts, be transported to outside the room of turbine buildings 1 near excavation portion 10 or its, assemble (S101), remove and transport, carry out the insertion (S103) of cooling tube etc. with reinforcement (S102).Then, finish (S104) at turbine generators basis platform, draw in set (S105) with board after, condenser body 4 as 2 blocks, from being located at the interim opening 8 on turbine buildings 1 outer wall, is pulled into platform 9 inner precalculated positions, turbine generators basis.Then, remove and draw in, restore interim opening (S107), carry out the waterproofing work (S108) of turbine buildings outer wall, the sitework of backfill etc. (S109) with gantry (S106).

The size of the interim opening 8 in this method is compared with the former approach of only moving into cooling tube, owing to be the interim opening of this body and function of condenser, interim opening 8 is big.In addition, when condenser is made monolithic devices, be predefined in factory and insert cooling tube, condenser body 4 is made near the shape of finished product transports, through moving into, draw in the precalculated position of the basic platform of turbine generators 9 inside from being located at interim opening 8 on turbine buildings 1 outer wall with jaw (figure do not show).

In above-mentioned any method, when the moving into of condenser body 4, use interim hoisting devices such as interim crane or interim hydraulic jack equipment.In addition, turbine buildings 1 is the stemming operation of excavation portion outside the engineering of constructing to the upper strata from lower floor and the room, considers the use of these interim hoisting devices, and aerial layer can not be constructed.Outer wall at turbine 1 is provided with interim opening 8, excavation portion 10 draws in condenser the method in platform 9 inner precalculated positions, turbine generators basis outside the room, excavation portion 10 is along with the circulating water pipe construction outside the room, be backfilling into condenser and draw in preceding height, so, for base stabilization is wanted the maintenance ground, the condenser precalculated position that is set to platform 9 inside, turbine generators basis with gantry of drawing in of condenser.In addition, on the condenser precalculated position of platform 9 inside, turbine generators basis,, implement to remove the operation of drawing in gantry for condenser being placed on the condenser basis.

The operation that removes of transporting with reinforcement is described below with reference to Figure 11.This Figure 11 is the example that condenser body 4 is divided into 2 partial status.In order to prevent to be installed with and to carry with reinforcement 17 because of transporting or move into the distortion displacement that operation produces.This transports with reinforcement 17 is interim parts before, removes after condenser body 4 is moved into.

The installation method of the 2nd kind of condenser for example as Japanese kokai publication hei 6-180383 communique is put down in writing, before crossbeam 12 constructions of turbine generators basis platform 9, carries out the condenser installation work.At this moment, because condenser is very big, only the weight of condenser body 4 will be used the ultra-large type hoisting device of interim setting just up to 600 tons (certainly, because of machine difference difference), moves into and hangs down.In addition, move into and hang down operation in order to carry out this, the aerial layer of turbine buildings 1, in the process of constructing or after constructing, the roof is demountable roof.

In this method, its order as shown in figure 12, except crossbeam 12, carry out the construction (S121) of turbine generators basis platform, carry out the setting (S123) of ground maintenance (S122) and ultra-large type hoisting device on the other hand, carry out move into (S124) of condenser body 4 with this ultra-large type hoisting device.Then, carry out crossbeam construction (S125), the turbine buildings aerial layer construction (S126) of turbine generators basis platform 9, remove ground maintenance (S127), carry out the disintegration (S128) of ultra-large type hoisting device.

But, in condenser before and the condenser method, have following problem.Promptly, opening portion from low pressure turbine 3 mounting portions of turbine generators basis platform 9, the condenser that to cut apart with the crane of interim setting hangs in the method that the installation site is installed, the size moved into of condenser, limited by the opening size of low pressure turbine 3 mounting portions, so the workload of erecting stage does not reduce.

In addition, must have and move into the interim opening 8 that cooling tube is used, before finishing, the cooling tube operation can not carry out the recovery of interim opening 8, so, the recovery of interim opening 8, turbine buildings 1 outer wall waterproofing work and be that the place engineering will postpone in configuration cycles water pipe, the stemming operation of excavation portion 10.

Outer wall at turbine buildings 1 is provided with interim opening 8, excavation portion 10 draws in condenser the method in platform 9 inner precalculated positions, turbine generators basis outside the room, also opening 8 temporarily, and this interim opening 8 is than above-mentioned interim opening 8 also greatly.In addition, excavation portion 10 is grounds of backfill behind the configuration cycles water pipe, so the weight of condenser makes its sinking, must carry out the ground maintenance.In addition, need be set to always platform 9 internal condensation device precalculated positions, turbine generators basis, condenser draws in the operation that removes with gantry.Therefore, can not carry out the recovery of interim opening 8 before these operations are finished, result, the outer wall waterproofing work of turbine buildings 1, the configuration cycles water pipe of excavation portion 10 and stemming operation are that place engineering etc. all postpones.Especially turbine buildings 1 is short with the distance of water circulating pump and heat exchanger buildings, in circulating water pipe and drainpipe complicated power house configuration, can not concurrent job, and so the duration lengthening.

Before crossbeam 12 constructions of turbine generators basis platform 9, when carrying out the condenser installation work, as Japanese kokai publication hei 6-180383 communique is put down in writing, can not influence the recovery, outer wall waterproofing work of the interim opening 8 of turbine buildings 1 or carry out the installation of moving into of condenser at excavation portion 10 configuration cycles water pipes or stemming operation ground, but because condenser is very big, its weight of the machine that has must use the interim ultra-large type hoisting device that is provided with to move into lifting up to 600 tons.

For this reason, must carry out maintenance, in addition, dispose the part of interim ultra-large type hoisting device, discrepancy and close restricted the ground that disposes interim ultra-large type hoisting device part.When especially being configured in turbine buildings 1 short brink, disposing the part of ultra-large type hoisting device and occupied, can not carry out other operation.When the ultra-large type hoisting device of interim setting when being fixed, must guarantee that body space is separated in the assembling of lifting beam, influence power house configured in one piece and engineering.

When the ultra-large type hoisting device of interim setting when being portable,, in its whole moving range, must carry out the maintenance of ground though the occupancy of hoisting device is short.In addition, moving in the lifting operation of condenser, must prevent the maintenance of wind and snow, when having constructed the roof, moving into when lifting of condenser must be carried out the switching operation on roof.Condenser must be installed in the inner narrow part of turbine generators basis platform 9 exactly, so during the influencing of wind-engaging, its centering operation is quite time-consuming, collides the pillar of turbine generators basis platform 9 sometimes.

Therefore, if big Modularly carries out, though the engineering of condenser itself can shorten, other operation increases, so the duration of the whole construction project in power house can not shorten, also causes product quality to reduce sometimes.

Summary of the invention

The present invention makes in view of the above problems, its purpose is to provide a kind of very effectively condenser installation method, in the method for the present invention, do not need the interim large lifting equipment that is provided with, can carry out the installation of condenser economically, in addition, do not influence the recovery, turbine buildings outer wall waterproofing work of interim opening or in excavation portion configuration cycles water pipe and stemming operation, be place engineering etc.
