Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for configuring a pump room underground that can be constructed in a single time and economically (2), and the pump room, and more specifically relates to a method for constructing a pump room underground. A hole is formed by excavating the ground to a specified width and depth, and then a foundation made of chestnut stone, etc. is constructed at the bottom of this hole. flat bottom plate blocks, dismantled blocks and straight wall blocks with holes for inserting inflow pipes and outflow pipes drilled at predetermined positions as necessary, eccentrically inclined cylindrical single-sided inclined blocks, adjustment rings, lid holder frames and lids, etc. are stacked in order, and these are each tied to each other with tie plates, anchor bolts, ring bolts, nuts, etc., and furthermore, an invert for installing the pump is integrally fixed on the bottom plate block via bolts, etc. The present invention relates to (3) a method of configuring a pump chamber and the pump chamber.

Conventionally, this type of pump room was constructed by drilling holes where the pumps were to be installed, assembling wooden frames, and then pouring concrete on site. It was difficult to erect 4t11 wooden frames etc. in one evening, and the poured concrete was completely dry (it took several days to harden), and the pump room made of concrete was difficult to construct. Before draining water, Ilj is difficult to design and code for installing inflow pipes, etc., and has the disadvantage of extremely high cost as a whole. Since the quality is not stable, it is easy to create a watertight, low-noise and low-vibration pump chamber with 4 ITM.
In fact, it had some drawbacks, such as the fact that its structure was extremely arranging.

The method and pump chamber according to the present invention have been developed in view of the drawback (4) of the conventional technology. The outer wall is formed by selecting blocks, single-sided inclined blocks, adjustment rings, etc. in order and stacking them on top of each other and connecting them with each other, and then fixing the invert for installing the pump to the bottom block and assembling the whole structure. This invention relates to a completely new technology that makes it possible to economically construct a pump chamber with stable quality in a short period of time.

To specifically explain one embodiment of the present invention with reference to the drawings, the first embodiment is as follows.
In Figures 6 to 6, first, an excavation hole with a predetermined width and depth is drilled in the ground at the location where the pump room is to be installed, and the bottom of the hole is compacted with chestnut or the like to form the foundation 1. ,
Next, on top of this foundation 1, an empty disk-shaped bottom block 2 (5), a cylindrical demolition block 6, cylindrical straight wall blocks 4 and 5, and an eccentric inclined cylindrical single-sided inclined block 6 are stacked in order. In addition, a gap 7 is formed at the inner circumferential wall engagement portion of these solid blocks 6, straight wall blocks 4.5, and single-sided inclined block 6, and this gap 7 is filled with rubber @8 and sealing material 9. This keeps the laminated portion watertight, and furthermore, the outer circumferential wall is tightly connected to each other by the fastening plate 10 and the fastening bolt 11, so that the whole is integrally constructed.

Next, on the one-sided inclined block 6 is a hollow disc-shaped adjustment ring 12, and a rectangular adjustment washer 1 made of a steel plate.
6. The lid receiving frames 15 to which the lids 14 can be attached are stacked in order, and the anchor bolts 16, ring bolts 17.
Bolt 18. These are interconnected and fixed by nuts 19, etc.

Further, an invert 20 for installing a pump is placed on the bottom block 2, and is fixed to this block 2 in two parts with anchor bolts 21.

Furthermore, holes 2 with a predetermined diameter are formed in the predetermined positions of the stone wall pipes 4 and 50.
2 are bored, and the end of an inflow pipe 26 or an outflow pipe 24 is fitted and fixed into these holes 22.

In the figure, 25 is a step attached to the inner peripheral wall of the pump chamber, and 26
27 is a pump installed and fixed in the invert 20, and 27 is a pipe arranged from the pump 26 to the outflow pipe 24.

As described above, the method of constructing the pump room according to the present invention is as follows: After drilling a hole in the ground where the pump room is to be installed, the bottom block, frame block, straight wall block, single-sided inclined block, etc. manufactured in advance at the factory are sequentially installed. Stacking (7) Since all you have to do is lay them down and connect them to each other, there is no need to assemble or dismantle wooden frames, unlike the conventional construction by pouring concrete on site.

It can be assembled and configured in a short time, and therefore, even on roads with a large amount of traffic, the pump room can be easily configured by a single hour of work at night, and each block etc. can be made uniform in advance. Since it can be manufactured in a factory, it is possible to configure a pump with stable quality, and by changing the number of stacked straight wall blocks, adjustment rings, etc., it is possible to freely configure a pump chamber of any depth. By preparing blocks with different diameters and textures, it is possible to freely configure pump chambers with different inner diameters and heights, making the design and construction of the pump chamber extremely simple. It is reliable, and requires an extremely small space for the excavation hole and construction site that constitutes the pump room (8) compared to conventional on-site concrete pouring, so it can be installed even in narrow spaces, making effective use of land. The holes for installing the outflow pipe and inflow pipe can be drilled as necessary in the factory etc. when shipping these blocks to the frame blocks and straight wall blocks, so the design and The construction is reliable, the work is stable and easy, and furthermore, in the pump chamber in which the present invention is implemented, the wall, the bottom plate block, and the invert made up of each block etc. are integrally integrated with each other as described above. Since it is connected and fixed, the pump can be installed and fixed in an inverted state in a stable manner.
Rubber rings and sealing materials are buried between each block, so it is possible to keep the wall water-tight, and the aforementioned Tarok wall, bottom plate, pump (9), etc. are integrated into a trap structure. Therefore, there is almost no vibration or noise during pump operation, and since the components of the pump chamber according to the present application can be manufactured in a factory, high quality products can be produced in Yasushi. It has characteristics.
