Description

  The present invention relates to a pump equipment structure and a construction method thereof.

  Conventionally, plants that use pumps to send and drain water and sewage and river water are reinforced concrete buildings that do not divide into small rooms for efficiency of maintenance, etc., or have a minimum size such as an electric room or ventilation room. The structure is divided into rooms.

  The structure of the facility is composed of, for example, a water tank (hereinafter referred to as a suction water tank) for taking water, a drainage facility building, and a water tank for water supply and drainage (hereinafter referred to as a discharge water tank).

  The construction procedure of the equipment is as follows: 1) Civil construction of suction tank and discharge tank, 2) Building construction, 3) Installation of overhead crane, 4) Installation of equipment and equipment, 5) Construction of indoor and outdoor water supply and drainage pipes, 6) Equipment Construction is carried out in the flow of small piping and wiring construction, 7) equipment trial operation.

By the way, the conventional method for a plant using a pump has the following problems.
For example, since it is not possible to install equipment at the same time as building construction, simultaneous work cannot be performed. Therefore, if the building is not rebuilt, a long construction period is required until the plant equipment is completed.

  In addition, in order to meet the delivery date, the building builder who performs the pre-process of the plant construction will not be able to communicate with the equipment installation contractor who will carry out the post-work with the installation equipment being undetermined. Since construction is performed, it is normal that an extra dead space is generated or a defect in the installation dimensions of the device occurs.

  On the other hand, the water supply / drainage facility is a large-sized device of about 20 tons, and does not require a large crane to suspend the device. In addition, rainwater drainage facilities and the like are often constructed in residential areas, so there is no large crane installation or temporary storage place for materials around the construction site of the water supply and drainage facilities. From the above, a construction method in which a building is assembled and assembled with a crane at a place adjacent to the installation place like a power plant cannot be performed.

  In nuclear power plants, there is a method of constructing the entire equipment as a unit and assembling the unit locally. However, the equipment is large and constructed in small rooms, and it is necessary to build it firmly with concrete or the like. For this reason, it is not easy to carry in / out the equipment at the time of regular maintenance after the completion of the equipment and to replace the equipment at the time of failure.

  On the other hand, in the case of facilities installed in residential areas, especially in the area of residence, the area of the site is often small due to the densely populated houses, while the area of the site is small The conflicting conditions of strict noise regulations must be satisfied. Therefore, it is important to install the building as small as possible, but the equipment installed indoors has a flexible layout plan in order to provide flexibility in selecting the manufacturer and to secure maintenance space for each equipment. Has been carried out, and the current situation is that the narrowing cannot be realized.

In addition, at present, orders are made for plants using pumps with delivery times of about one year. Therefore, the building construction and the work for equipment installation cannot be performed in order, and they are performed simultaneously.
For this reason, as described above, civil engineering construction work and equipment contractors are mostly separate constructions independent of each other, and construction work is performed independently at different times. However, since the required accuracy differs greatly, there may be a problem that the facility joint portion once implemented does not match. In particular, a pump and a driving machine such as an engine or a motor for driving the pump need to be centered so that the centers of the rotating shafts are arranged in a straight line, and a number of processes are required on site. For this reason, if there is a problem in the equipment connection section, the facility once completed will be dealt with by refurbishment, re-installation, re-painting, equipment change, etc. by the equipment contractor, and there will be a lot of rework.

There are restrictions on the size of trailers that can be transported when considering transportation of equipment to residential areas. For this reason, it is difficult to construct and ship equipment as a unit.
Moreover, since the shape of the water absorption tank is a civil engineering structure determined for reasons such as suction vortex generation and pump drainage capacity, it is necessary to construct a water tank locally, and so far no generalization has been performed.

  In order to solve the above-described problems of the prior art, the present invention aims to provide a pump facility structure that can be constructed quickly and that does not require rework, and that can be easily maintained and replaced. And

In order to achieve the above object, a pump facility structure according to the first aspect of the present invention includes a plurality of units having a rectangular parallelepiped shape of the same size constituting the structure, and an upper side in which the ceiling is formed. A plurality of units arranged in a horizontal direction or stacked in a vertical direction, and some of the equipment are locally installed Prior to installation at the position, the position is adjusted in a state of being installed in the unit in advance .

A pump facility structure construction method according to the second aspect of the present invention is a pump facility comprising a plurality of units having a rectangular parallelepiped shape of the same size constituting the structure, and a facility device that is installed in the unit and can be replaced and replaced. a method for constructing a structure, precision out said equipment required of the equipment to be installed in the unit in advance before the pump equipment structure is installed in a local constructed, the After being assembled in the unit and precision-decomposed, it is disassembled, and at the site, the plurality of units are built side by side or stacked vertically to form the ceiling of the unit From the upper space, the equipment is installed in the unit, and the equipment that requires accuracy out of the equipment is fixed after level accuracy is obtained. Is installed, the electrical connection of wiring the equipment is being performed.

  According to the present invention, it is possible to realize a pump facility structure and a method for constructing the pump equipment that can be constructed in a short delivery time, have no rework, and can be easily maintained and replaced.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a partially cutaway perspective view showing the inside of a pump facility according to an embodiment of the present invention, and FIG. 2 is a view in the direction of arrow A in FIG.
The present invention relates to a plant construction method, and particularly relates to a module structure suitable for plant equipment and a technology related to plant construction.
As an example of a plant to which the structure of the present invention is applied, a drainage pump facility S will be described below.

The drainage pump equipment S of the embodiment is constructed by connecting and fixing units U (U1, U2, U3,...) Of the same size in the horizontal direction and / or the vertical direction.
The drainage pump facility S is composed of a large number of facility devices in addition to the drainage pump 1 at the center, and various facility devices and a large number of small pipes are formed around the drainage pump 1.
The drainage pump 1, various equipment, and a large number of small pipes are installed in a unit U having the same size.

  As shown in FIGS. 1 and 2, a drain pump 1 is installed in the unit U1, and a speed reducer 4 and a speed reducer fixed to the shaft of the drain pump 1 are installed in a unit U2 adjacent to the unit U1 in the horizontal direction. A prime mover and an engine 3 fixed to the shaft 4 are fixed. In this drainage pump facility S, description will be made assuming that the engine 3 is mounted.

The unit U3 adjacent to the unit U2 is provided with a silencer 5 connected to the engine 3. A fan 6 for cooling the engine 3 is connected to the engine 3 outside the units U3 and U7. It is installed through the duct 7.
<Unit U>

FIG. 3 is a partially cutaway perspective view showing the structure of the unit U. FIG.
Each unit U has the same size and has a container-like rectangular parallelepiped shape. Since all the units U have the same size, the structure can be easily expanded and replaced. That is, the unit U has a structure that can be stacked in a plurality of stages.
Further, the ceiling of the unit U has a removable structure, and has the feature that the unit U and equipment can be removed with a rough terrain crane.

The unit U includes a frame-shaped support frame h that forms each side, and a wall-shaped plate portion i that is fixed to the frame-shaped support frame h.
The frame-shaped support frame h includes a front upper support frame h1, a front lower support frame h2, a front right support frame h3, a front left support frame h4, a rear upper support frame h5, a rear lower support frame h6, a rear right support frame h7, It has a rear left support frame h8, an upper front / rear right support frame h9, an upper front / rear left support frame h10, a lower front / rear right support frame h11, and a lower front / rear left support frame h12.

The wall-shaped plate portion i includes a top plate i1, a bottom plate i2, a front plate i3, a rear plate i4, a right side plate i5, and a left side plate i6.
When the unit U is not exposed to the external space or when the unit U is disposed inside, the plate portion i may be configured without being provided as appropriate. For example, in a building, the plate portion i of the wall surface is basically unnecessary, and thus the plate portion i of the unit U is often configured only when it is an outdoor wall. Thus, the plate part i of the unit U may be provided as necessary. Thus, a flexible design is possible, such as providing the plate portion i on the outdoor wall and not providing the plate portion i indoors.

By not providing the plate part i, it is possible to reduce costs such as material costs and assembly costs, and weight. For example, the unit U may be configured to include only the support frame h and not to provide the plate portion i. As a result, the effects of cost reduction such as material cost and assembly cost and weight reduction are great.
Each plate portion i has an opening formed according to the state of the facility, or a door formed with a hinge so as to be freely openable / closable, and the form thereof is arbitrarily formed according to the facility.

The support frame h (h1 to h12) is formed of a strength member having high bending strength and torsional strength such as a square pipe or H-shaped steel.
For the plate portion i (i1, i2, i3, i4, i5, i6), for example, a corrugated steel plate having a thickness of about 2 mm is used. The plate part i is a corrugated steel plate, so that the strength is higher than that of a flat steel plate.

  The support frame h and the plate part i are each manufactured by using a material that is rust-proofed by plating or the like, or that suppresses rust. The support frame h has a strength and a structure that does not affect the strength even if the plate portion i of the unit wall is removed.

The plate part i and the support frame h are joined by welding to form an integral structure. The plate part i and the support frame h may be appropriately fixed with bolts, and may be attached and detached.
The top board i1 has a structure that can be freely opened and closed, so that installation and maintenance of equipment (1, 3, 4, etc.) and equipment can be taken out. Therefore, the top plate i1 is fixed to the front upper support frame h1, the rear upper support frame h5, the upper front / rear right support frame h9, and the upper front / rear left support frame h10 by a bolt, and is configured to be detachable or openable. .

When the unit U has a first-floor structure (one-stage structure) in the vertical direction, the support frame h is not provided, and the plate portions i may be joined to each other by welding.
The drainage pump facility S is preliminarily assembled in the unit U in the factory, and various equipment and devices are adjusted for accuracy, then disassembled, transported to the site, and reassembled in the unit U at the site. Therefore, the drainage pump facility S has an excellent feature that it is extremely easy to construct locally, is constructed with a short delivery time, and the positional accuracy of each facility device is high.

<Water absorption tank 2>
FIG. 4A is a side sectional view of the periphery of the water absorption tank under the drain pump and the periphery of the pump base for fixing the drain pump. FIG. 4B is a side view showing a shim for adjusting the height of the pump base. FIG.
The water absorption tank 2 in which the drainage pumped up by the drainage pump facility S is stored is constructed in the ground. Although the water absorption tank 2 can be manufactured even by individual production, the construction with a box culvert bx1 that is standardized in consideration of generalization is shown.

  The water absorption tank 2 is constructed of a box culvert bx1 with a bottom plate portion 2t constructed from concrete. Moreover, the suction water channel which continues to the water absorption tank 2 is constructed by connecting a plurality of box culverts bx. An opening bxa is provided in advance at one place where the box culvert bx1 forming the water absorption tank 2 is provided, and the suction pipe 1s of the drainage pump 1 is inserted into the opening bxa.

<Installation of drainage pump 1 and level adjustment>
In installing the drainage pump 1, it is necessary to maintain water tightness among the box culvert bx1, the building floor (the bottom plate i2 of the unit U), and the main pump suction pipe 1s.
Therefore, the pump base 1b is directly installed in the box culvert bx that forms the water absorption tank 2. In addition, since the pump base 1b needs to ensure the accuracy of the horizontality and the verticality within a predetermined value, after the construction of the culvert bx1 constituting the water absorption tank 2, each level adjustment of the horizontality and the verticality is performed on site. Meanwhile, the drain pump 1 is installed.

A donut-shaped (hollow disc-shaped) pump base 1b shown in FIG. 4A is fixed to an opening bxa of a box culvert bx1 constituting a water absorption tank 2 by an anchor bolt a1.
The drainage pump 1 is fixed by screwing a bolt bo inserted into the mounting portion 1t of the drainage pump 1 into the pump base 1b fixed to the box culvert bx1.

  Level adjustment with the drainage pump 1 is performed by appropriately sandwiching a level adjusting taper liner sm shown in FIG. 4B between the box culvert bx1 and the pump base 1b, and adjusting the position and adjusting the accuracy of horizontality and displacement. I do.

  In the installation including the level adjustment of the drainage pump 1, the anchor bolt is first tightened in such a manner that the taper liner sm is sandwiched between the pump base 1b and the box culvert bx1. In this state, adjustment is made to the target position while moving the taper liner sm. At a stage where accuracy has been achieved, after confirming that the pump base 1b is tightened again without any problem, the taper liner sm is fixed by welding, and concrete is packed and hardened so as to cover the pump base 1b.

  The prime mover, the engine 3 and the speed reducer 4 for driving the drainage pump 1 need to be aligned with the main shaft 1j (see FIG. 2) of the main pump. Adjust the centering in the factory.

  However, when the diameter of the drainage pump 1 is increased, the drainage pump 1, the prime mover, the engine 3, and the reduction gear 4 cannot be installed in the same unit U. In that case, as shown in FIGS. 1 and 2, the main pump 1, the prime mover or engine 3, and the speed reducer 4 are installed across the adjacent units U1 and U2. Specifically, the level adjustment in the horizontal direction and the vertical direction (vertical direction) is performed at the factory in order to align the main pump 1 of the unit U1, the prime mover, the engine 3, and the speed reducer 4 of the unit U2. Then, it will be carried to the site.

Further, assuming a case where the accuracy of alignment is not obtained locally for some reason, a mechanism (jack bolts j1 to j8, etc.) capable of readjusting the level is provided as shown in FIG.
FIG. 5 (a) is a front view showing a configuration in which a reduction gear is installed on a mounting base and includes a jack bolt as a level readjustment mechanism, and FIG. 5 (b) is a top view around the reduction gear. It is. The speed reducer 4 and the engine 3 are expressed in a box shape for easy understanding.

<Level adjustment of reducer 4>
A steel frame (not shown) is arranged on the bottom plate i2 in the unit U. On the steel frame of the bottom plate i2, mounting bases d1 and d2 are joined with bolts.
The engine 3 is installed on the installation table d1, and the speed reducer 4 is installed on the installation table d2.
Bolt support plates s1 to s8 are erected on the mounting base d2, and jack bolts j1 to j8 are movably screwed to the bolt support plates s1 to s8, respectively.

The jack bolts j <b> 1 to j <b> 8 are provided so that the speed reducer 4 can be adjusted in the horizontal direction by pressing the speed reducer 4 in the horizontal direction. With this configuration, by adjusting the position of the jack bolts j1 to j8 at the site, the speed reducer 4 is pressed to the desired position in the horizontal direction by pressing the speed reducer 4 with the jack bolts j1 to j8. Adjustments can be made. After the adjustment, the speed reducer 4 is fixed with a fixing bolt (not shown).
In addition, the other equipment of the drainage pump equipment S may be configured to include a mechanism capable of readjusting the level such as jack bolts j1 to j8, similarly to the speed reducer 4.

<Auxiliary equipment 9>
6 is a view in the direction of the arrow B in FIG. 1, and FIG. 7 is a top view of the pump facility in FIG.
As shown in FIGS. 6 and 7, the auxiliary equipment 9 such as a vacuum pump and an air compressor is easy to perform equipment maintenance such as short installation of piping and concentrating and laying of conduits in which the wiring r is gathered. By narrowing the design in consideration of the above and the like, the unit U10 is integrated and installed in an appropriate place on the bottom plate i2 forming the floor surface of the unit U10. As a result, the space in the unit U can be used widely, the work space can be expanded, and the space in the unit U can be effectively utilized.

<Connection between units U>
Fig. 8 (a) is a front (side cut) view showing the fixing between the units and the piping connection between the units. Fig. 8 (b) shows the fixing between the units and the piping connection between the units. It is the top view shown. FIG. 9A is a perspective view of a fixing portion between the units in FIG. 8A as viewed obliquely from above, and FIG. 9B is a perspective view showing a template tp.

The pipes k1 and k2 extending between the units U are manufactured up to the boundary before the units U so that the units U can be connected after the field installation.
The pipes k1 and k2 are fixed and supported by supports s1 and s2 fixed to the unit U, respectively.

  The pipes k1 and k2 between the units U are basically connected through a short pipe with a flange, but as shown in FIGS. 8A and 8B, they are flexible for displacement adjustment. A flexible tube t1 with

  On the other hand, as shown in FIG. 8B, the connection between the units U is performed by lightly driving the reamer bolts rb1 and rb2 into the reamer-finished holes ua formed in the plate portion i connecting the units U. Tighten and fix.

At the corners of the unit U, through bolts tb1 and tb2 are inserted between the support frames h (or the plate part i) between the units U, and tightened with nuts n2 from both sides.
As shown in FIG. 9A and FIG. 9B, the template tp is used to connect the bottom plates i2 between the units U.

In the template tp, a mounting hole tp1 for a through hole for positioning the connection between the units U is formed at a predetermined position at a predetermined position.
That is, the bottom plates i2 between the units U are connected to each other by fixing the bottom plates i2 between the units U or the support frames h of the steel frame with the bolts bt inserted through the mounting holes tp1 of the template tp. Reproduce and achieve the same connection accuracy as the factory.
In other words, the attachment hole tp1 of the through hole of the template tp is formed at a predetermined position, and the hole formed in the unit U is fixed according to the predetermined position of the attachment hole tp1 of the template tp. Connection can be performed with the same connection accuracy as the factory.

  As shown in FIG. 9A, at least two templates tp are arranged on each side connecting the units U. By disposing at least two templates tp on each side, the unit U is reliably connected and fixed with high positional accuracy without being displaced such as tilting. By arranging the templates tp and tp on each side at positions that are separated from each other, the inclination between the units U is reduced and the accuracy is further improved.

<Control panel C>
FIG. 10A is a top view showing an arrangement example of the control panels housed in one unit U. FIGS. 10B and 10C are details of the arrangement of the control panels housed in one unit U. FIG. It is a top view which shows an example.
The control panel C responsible for controlling the drainage pump equipment S is designed to be narrow so that it can be accommodated in one unit U, thereby improving the arrangement space of components and the efficiency of wiring.

  Since the control panel C is collectively designed, it is not necessary to divide the unit into units such as a power panel, auxiliary panel, and pump panel. In some cases, one unit U is constructed as a control room, and the control room of the unit U A structure in which indicator lights and switches are attached to the outer wall surface of the housing. The wall surface on which the indicator lamps and switches are installed can be mounted either on the inside or outside of the unit U or on the inside or outside of the building composed of a plurality of units U.

Hereinafter, an example of the control panel C housed in one unit U is shown in FIG.
As shown in FIG. 10 (a), the unit U in which the control panel C is disposed includes a space Ua in which the incoming power receiving panel C1 is disposed, a transformer room Ub in which the transformer C2 is disposed, and an operation panel C3. It is divided and arranged in the space Uc to be arranged. The transformer room Ub is provided with a door dr1, and the space Uc is provided with a door dr2.

In the space Ua, a lead-in power receiving panel C1 is mounted with power supply-related mounted products and components connected to the wall by wiring.
The transformer C2 is placed in the transformer room Ub.

  As shown in FIGS. 10B and 10C, in the space Uc, as the operation panel C3, a power circuit C3a for supplying power and a control circuit C3b responsible for control are exposed in the internal space of the space Uc. Then, electrical components, electrical wiring, etc. are fixed and mounted on the iron plate. That is, unlike the conventional case, the operation panel C3 is configured such that an iron case that covers the power circuit C3a and the control circuit C3b is not provided.

  Conventionally, a power circuit and a control circuit constituting an operation panel are each mounted on an iron plate, and these are housed in a hexahedral iron case. Therefore, the operation panel C3 having the power circuit C3a and the control circuit C3b is restricted by the size of the hexahedral iron case, and has a disadvantage that a large space is required to accommodate the case.

  On the other hand, in the drainage pump facility S, a power circuit C3a and a control circuit C3b, in which electrical parts, electrical wiring, etc. are fixed and mounted on an iron plate installed in one unit U by screws or the like, It is exposed and disposed in the internal space. Thus, by configuring the operation panel C3 of the drainage pump facility S without providing a hexahedral iron case, a wider space can be secured in the unit U.

<Wiring connection between units U>
FIG. 11A is a top view showing the configuration of wiring connection between units, and FIG. 11B shows the configuration of the wiring connection portion between units in a state where the door of the terminal box is opened from an obliquely upper side. FIG.
Since the wiring r (r1, r2) of each device from the control panel C (C1, C2, C3) in the drainage pump facility S basically spans between the units U, the wiring is routed after the unit U is installed on site. Connect.

  As shown in FIG. 11B, the electrical connection between the units U is a relay terminal block for connecting the wiring r (r1, r2) to the support frame h and the plate part i at the corners of the unit U. A terminal box Tx (Tx1, Tx2,...) Having Cd (Cd1, Cd2,...) Inside is equipped.

  In consideration of safety, the terminal box Tx is provided with a door Txa that can be freely opened and closed. Normally, the door Txa is closed, and the relay terminal block Cd of the wiring connection portion between the units is covered in the terminal box Tx. Then, the door Txa is opened at the time of connection of the wiring r at the time of construction or at the time of maintenance. The terminal box Tx is provided with a door Txa, and normally the safety can be enhanced by closing the door Txa.

  For each unit U, the wiring r coming from the mounted product (equipment (1, 3, 4, etc.), panel (C1, C2, C3)) installed in each unit U is connected to the terminal box Tx in the unit U. Connect to the terminal of the relay terminal block Cd.

As shown in FIG. 11 (b), the connection of the wiring r (r1, r2) between the units is not an outdoor wiring, so that the terminal box Tx1 and the terminal box in the terminal boxes Tx1, Tx2, which are unit connection portions, are connected. The plate part i serving as a boundary with Tx2 has an opening ia, and can be connected through the opening ia. Thereby, since outdoor wiring can be avoided, the electrical connection part between wiring r1, r2 is exposed to a wind and rain, and can prevent failures, such as an electrical leakage, beforehand.
In addition, it is good also as a structure which does not provide board part i itself used as each boundary in terminal box Tx1, Tx2.

  As shown in FIG. 11A, the wiring r1 from each device (1, 3, 4, etc.) in the unit U of the drainage pump equipment S to the terminal (not shown) of the relay terminal block Cd1 in the terminal box Tx1. Is installed in advance. In addition, wiring r2 from the power circuit C3a, the control circuit C3b, etc. in the unit U in which the control panel C is disposed to the terminal (not shown) of the relay terminal block Cd2 in the terminal box Tx2 is performed in advance.

  As shown in FIG. 11B, the electrical connection of the wirings r1 and r2 between the units U is performed between the terminals of the relay terminal blocks Cd1 and Cd2 in the terminal boxes Tx1 and Tx2, and the wiring r1 through the opening ia. , R2 are electrically connected.

The wiring r between the units U is connected one by one, and in order to save the trouble of rewiring, several wirings r are bundled together into a connector shape or divided terminals. It is good also as a structure which fits with the connector or terminal block of the other party using a stand, and connects collectively.
By using a connector or a split-type terminal block, the wiring r can be easily connected, reconnected, maintained, and the like.

  On the other hand, since the power line has a large diameter, after connecting the unit U, the control panel (C3) and the devices (1, 3, 4, etc.) are directly connected (the fuel transfer pump 29 and the private power generation in FIG. 16). (Refer to connection of equipment JH).

In the wiring connection process between the units U described above, a connection test of the wiring r is first performed at the factory.
After the test is completed, disconnect the wiring r once for delivery to the site.
After the units U and the like are brought into the field and each unit U is installed on the field, the door Txa of the terminal box Tx is opened, and the connection of the wiring r between the units U is performed again in the same manner as in the factory test. After the connection of the wiring r is completed, the door Txa of the terminal box Tx is closed. Then, the operation panel C3 of the unit U where the control panel C is placed is operated to turn on the power, and the drainage pump facility S is operated.

<Assembly of unit U of drainage pump equipment S>
Next, a method for assembling the unit U of the drainage pump facility S will be described.
The floor surface of the first-stage unit U in the vertical direction (one of the bottom plate i2 and / or (front lower support frame h2, rear lower support frame h6, lower front / rear right support frame h11, lower front / rear left support frame h12, etc. In 3)))), considering the earthquake resistance, install the floor to the foundation firmly with foundation bolts.
The unit U can be stacked in the vertical direction as well as in the horizontal direction.

12A and 12B are perspective views showing an example of the arrangement of the units U in the horizontal direction.
As shown in FIG. 12A, the basic unit U is installed in close contact with each unit U, and the adjacent units U are respectively connected to the above described reamer bolts rb1, rb2, and through bolt tb1 using the template tp. , Tb2, template tp, etc., connect adjacent units U (see FIGS. 8 and 9).

On the other hand, when the shape of the water channel to be installed is determined in advance, as shown in FIG. 12B, the beam H1 on the side constructed by the civil engineer forming the water absorption tank 2 is too large, and the units U are directly connected to each other. If the dimensions do not match when connected, do the following:
Adjacent units U are separated and installed, and an adjustment wall Ck and a ceiling Ct are incorporated between the adjacent units U.

  As shown in FIGS. 1 and 2, the second floor (unit U stacked in the second stage in the vertical direction) is provided with ventilation equipment such as a silencer 5 and a fan 6, but the 1F room (vertical direction) In consideration of heat countermeasures in the first-stage unit U), the top plates i1 and 2F (vertical second-stage unit U) in the 1F room (vertical first-stage unit U) floor bottom plate i2 is basically absent. Since the ventilation equipment such as the silencer 5 and the fan 6 is lightweight, the front upper support frame h1, the rear upper support frame h5, the upper front and rear right sides of the ceiling of the second floor (unit U stacked in the second stage in the vertical direction) The installation location is free, such as hanging from the support frame h9, the upper front / rear left support frame h10, the top plate i1, or the like.

  The management room for managing the drainage pump facility S has a low relevance to the equipment (1, 3, 4, 5 etc.) (see FIG. 1), so 1F (vertical first unit U) , 2F (second unit U in the vertical direction) can be installed. In the case of 2F installation, stairs are installed outside the unit U for the purpose of traffic. The stairs can be installed indoors as long as there is room for installation indoors (in the unit U).

As described above, the connection between the units U excluding the box culvert bx1 of the water absorption tank 2 and the connection with the bottom plate i2 between the units U are configured by bolt joining.
Specifically, in order to make the connection between the units U equivalent to the accuracy of the factory, the template tp for inter-unit connection shown in FIG. At the time of field installation, connection and installation between the units U are performed using the template tp, the reamer bolts rb1 and rb2, the through bolts tb1 and tb2, and the like.

  The top plate i1 forming the ceiling of the unit U shown in FIG. 3 is installed at the front upper support frame h1, the rear upper support frame h5, The front and rear right support frame h9, the upper front and rear left support frame h10, and the like are fixed with bolts, and the bolts can be removed or tightened to be opened and closed.

Then, the chain block Cb1 and the rail Cr1 for moving the chain block are installed in the unit 32 on the second floor. There is no plate portion i between the unit U32 on the second floor and the unit U31 on the first floor.

Thus, since the drainage pump facility S3 is configured to extend upward, the unit U is not installed in the spaces p1, p2, and p3 around the unit U31 as shown in FIG. 18B.
Pattern 4 in FIG. 14 is an example of the drainage pump equipment S4 when the horizontal axis pump and the drive source are motors.

<Construction of drainage pump equipment S>
Construction of the drainage pump equipment S (S1, S2, S3) is performed in the following procedure.
First step. First, necessary units U having the same size and equipment are prepared.
Second step. Of the equipment (1, 3, 4, etc.) placed in the unit U, equipment that requires accuracy is assembled in the unit U in the factory (manufacturing site), disassembled after accuracy is determined. .

Third step. Unit U and equipment installed in unit U are carried into the construction site of drainage pump facility S.
Fourth step. The units U are connected to each other by bolting using the template tp, the reamer bolts rb1 and rb2, the through bolts tb1 and tb2, and the unit U is installed on the site. And the installation apparatus is installed in the unit U by the rough terrain crane Rc from the space where the top plate i1 of the unit U is removed. In addition, the installation of equipment (such as the drainage pump 1) that requires level accuracy is fixed and installed after the level accuracy is achieved (see FIGS. 4A and 4B).

5th process. Although it is necessary to determine the position accuracy of the equipment, the accuracy is determined (see FIGS. 5A and 5B).
Sixth step. The top plate i1 of the unit U is attached by bolting.
Seventh step. Electrical connection of the wiring r of the equipment is performed (see FIGS. 11A and 11B).
The fourth to sixth steps are appropriately performed as necessary.
Thus, the drainage pump facility S (S1, S2, S3) is completed.

According to the above configuration, the drainage pump facility S (S1, S2, S3) is constructed by connecting and fixing units U of the same size. Therefore, the construction period is shortened and the working scaffold can be reduced.
At the time of construction, as shown in FIG. 19A, the unit U can be moved by the rough terrain crane Rc, and the unit U can be installed in the horizontal direction or stacked in the vertical direction. Moreover, the equipment (3, 4, 5, etc.) installed in the unit U can be installed from the top by removing the top plate i1 of the unit U as shown in FIG.

  Therefore, as in the conventional comparative example shown in FIG. 19B, the space ph that the truck Tr carries in for installing the equipment can be significantly reduced. Fig. 19 (a) is a top view showing the delivery of the unit U at the site of the pump equipment of the embodiment and the construction status, and Fig. 19 (b) shows the delivery of the pump equipment of the comparative example to the site. It is a top view which shows the construction condition.

  In addition, the drainage pump facility S is installed in the unit U in the factory in advance, and the accuracy is improved and disassembled. Then, the drainage pump facility S is carried into the site and assembled and installed at the site as in the plant. . Since equipment is installed in the unit U in the factory in advance to obtain accuracy, assembly with high accuracy can be performed. Therefore, fine adjustment is sufficient even when accuracy adjustment is required.

  In addition, the painting of the equipment is only required for the first time, and repainting is unnecessary. Conventionally, the first painting is performed at the time of parts production, the parts are assembled and subjected to on-site inspection, disassembled, the second painting for shipping, the second painting for installation, and the third painting after installation. A process was required.

Furthermore, since the units U are arranged in the horizontal direction or stacked in the vertical direction, future expansion can be easily handled, and replacement of each unit U is easy.
Further, when performing maintenance of equipment and the like, it is performed using a rail Cr1 (Cr2) and a chain block Cb1 (Cb2) for movement of the chain block that can be attached and detached near the ceiling plate i1 of the unit U. So maintenance is easy. The chain block moving rail Cr1 (Cr2) and the chain block Cb1 (Cb2) may be left as they are, or can be easily removed if not necessary.
This eliminates the need for a conventional permanent overhead crane.

  From the above, it is possible to construct a unit U in which an architectural building and equipment are integrated in a manufacturing factory in advance, disassemble after adjustment, and pile up locally. Therefore, construction of building buildings and equipment can be done in a short period of time, there is no rework, maintenance and equipment can be easily replaced, and a plant for water supply and drainage equipment with high installation positional accuracy and its construction method are realized. it can.
