Description

[Detailed description of the invention] The present invention relates to an invert structure for mounting a pump that can prevent solid matter from accumulating at the bottom of a pump chamber and can stably attach and fix the pump thereto. The invert, which has a flat recess at the bottom for installing the pump and whose outer periphery stands up in a mortar shape to form a tapered peripheral wall edge, is integrally attached and fixed to the bottom plate at the bottom of the pump chamber via bolts, etc. The present invention relates to an invert structure for mounting a pump, which is characterized by having a structure in which:

In conventional pump chambers, a substantially flat pump mount was installed at the bottom of the pump chamber, and the pump was mounted on this mount. There is a disadvantage that solids such as sand contained in the running water flowing into the pump room are deposited on almost the entire bottom of the pump room, and if the bottom of the pump room is flat, it is necessary to secure a foothold for work. There were drawbacks, such as the fact that it was difficult to

The present invention is a completely new technology developed in view of these drawbacks of the conventional technology, in which the invert for flowing water used in sewage manholes is configured in a special shape, and it is installed at the bottom of the pump room. ,
By integrally attaching and fixing this to the bottom plate via mounting bolts, etc., and attaching and fixing the pump to the flat recess in the center of this invert, the solid matter collected in the recess can be absorbed. This invention relates to a completely new technology that makes it possible to prevent solid matter from accumulating on the bottom surface of the pump chamber and to secure a working foothold inside the pump chamber.

One embodiment of the structure according to the present invention will be explained in detail with reference to the drawings. 1 is a pump chamber, a bottom plate 2,
It is composed of a straight wall pipe 3, an inclined wall pipe 4, a lid frame 5, a lid 6, an inflow pipe 7, etc. Next, 8 is an invert installed at the bottom of the pump chamber 1, which has a flat recess a for installing the pump in the center of the inner bottom, and a tapered peripheral wall edge b that stands up in a mortar shape on its outer periphery. The upper surface of the peripheral wall edge b is provided with a smooth surface c, and the invert 8 is integrally and firmly fixed to the bottom plate 2 of the pump chamber 1 via mounting bolts 9.

In the figure, 10 is a pump installed in the flat recess a of this invert 8, and 11 is a discharge pipe connected to this pump 10.

As described above, the invert structure for mounting a pump according to the present invention is such that a specific invert having a flat recess at the center bottom and a mortar-shaped tapered peripheral wall edge at the outer periphery is installed at the bottom of the pump chamber. Since the pump is installed in the flat recess of the invert, this automatically collects solids such as sand contained in the water flowing into the pump chamber into the recess at the center bottom of the invert. These can be smoothly discharged by the pump, thereby preventing solid matter from accumulating at the bottom of the pump chamber, and a smooth surface is formed on the upper surface of the peripheral wall edge of the outer periphery of the invert. Therefore, this part can be used as a scaffold for work inside the pump chamber, and since the invert is integrally attached to the bottom plate via fixing bolts, it strengthens the bottom of the pump chamber and stabilizes the pump. Moreover, since this invert has a large outer peripheral area, it has the advantage of being able to be fixed widely and stably to the inner peripheral wall surface of the pump chamber.
