3.7.3 concreting
1) it before casting concrete, should first carry out an acceptance inspection, the sundries in template should be cleaned out, to template to template
Gap and hole should give stifled tight.
2) it pours using C30P6 commerical ready-mixed concrete.Cobble-stone diameter is less than 10mm.Segregation phenomenon cannot occur in pouring.
3.8 sealing off and covering anchorage
Extra steel strand wires 3 are cut off, will be blocked at 400 top suspension hook of anchorage hole and prefabricated board with mortar.
4, closed-water test
Fermentor is secondary pour after the completion of, the secondary airtightness poured is detected, in fermentor place 50cm high
Water, the secondary concrete poured is checked after 48 hours whether there is or not leakage phenomenon, ne-leakage phenomenon is qualification, there is the use of leakage phenomenon
Sealant is handled seam is leaked out, until qualified.
5, tank deck and related Zymolysis Equipment are installed.
Zymolysis Equipment includes: feed pipe, blow-down pipe, overflow pipe, blender, heating coil, circulator, thermal insulation material etc..
The structure of the fermentor made of the above method is as follows in the present invention:
As shown in Figure 5, Figure 6, prefabricated board assembly fermentor, including tank skin 100, the tank deck being arranged at the top of tank skin 100
200 and the tank bottom 300 of 100 bottom of tank skin is set；Wherein, tank skin 100 includes several prefabricated boards 400, and prefabricated board 400 wraps
Include the first prefabricated board of muti-piece 1, the second prefabricated board of muti-piece 2 and more steel strand wires 3；Each first prefabricated board 1 circumferentially cloth at equal intervals
It sets, each second prefabricated board 2 is arranged between each first prefabricated board 1, and each second prefabricated board between two first prefabricated boards 1
2 head and the tail are sequentially connected, and are assembled into closed tank skin 100 jointly with the first prefabricated board 1；Each steel strand wires 3 run through the first prefabricated board 1
With the second prefabricated board 2, and the first prefabricated board 1 and the second prefabricated board 2 are connected as one.
Further, such as Fig. 7, as shown in figure 8, section can be used in circular arc in the first prefabricated board 1 and the second prefabricated board 2
Plate keeps the tank skin 100 being assembled into jointly by the first prefabricated board 1 and the second prefabricated board 2 annular in shape.
It should be noted that the cross sectional shape of the first prefabricated board 1 and the second prefabricated board 2 can be adapted to according to need of work
Property transformation, however it is not limited to the interior of the first prefabricated board 1 and the second prefabricated board 2 also can be used in planform defined by above description
Side be it is arc-shaped, lateral surface is arbitrary shape；The cross section of first prefabricated board 1 and the second prefabricated board 2 is " L " type；First is pre-
Making sheet 1 and the second prefabricated board 2 are plate etc.；Meanwhile first prefabricated board 1 and the second prefabricated board 2 tank skin 100 that is assembled into
Shape is also not limited to planform defined by above description, and the section in the space being assembled into for polygon or can not also advise
Then shape.
Such as shown in Figure 11,12, the first prefabricated board 1 and the second prefabricated board 2 are slab construction, and for the ease of the
Splice between one prefabricated board 1 and the second prefabricated board 2 and position, a side of the first prefabricated board 1 can be set to the arc of strip
Protrusion 11, another side is set as groove 12, sets a side of the second prefabricated board 2 to the arc convex 21 of strip, another
Side is set as groove 22, and arc convex 21 can be in mating connection with groove 12,22, and arc convex 11 can match with groove 22
Connection is closed, the shape for the tank skin 100 that the first prefabricated board 1 and the second prefabricated board 2 are surrounded can be pre- according to the first prefabricated board 1 and second
The connection angle of making sheet 2 is changed, to adjust the shape of tank skin 100.
For the ease of the installation and fixation of steel strand wires 3, as shown in fig. 7, can integrally be set on the lateral wall of the first prefabricated board 1
The fixed part 4 of a protrusion is set, the two sides of fixed part 4 offer multiple mounting holes 41 respectively, and mounting hole 41 is for fixing steel strand wires
3.Wherein, the number of mounting hole 41 is corresponding with steel strand wires 3 with position.
It should be noted that fixed part 4 can be arbitrary structures, as long as guarantee is with symmetrical and regular side
Can, that is, meet opening up for mounting hole 41.
As shown in Figure 7, Figure 8, each steel strand wires 3 run through each first prefabricated board 1 and each second prefabricated board along the circumferential direction of tank skin 100
2 inside, and the both ends of each steel strand wires 3 are stretched out from each first prefabricated board 1 respectively and are plugged on the correspondence mounting hole of fixed part 4
It in 41, and is fastenedly connected with mounting hole 41, to prevent steel strand wires 3 mobile, the shape of tank skin 100 is caused not can guarantee.
For the ease of the installation of steel strand wires 3, it can offer and be used in the inside in the first prefabricated board 1 and the second prefabricated board 2
