Description

Reservoir overflow weir formula overflow well structure

Technical Field

The utility model relates to a building field especially relates to a cistern overflow weir formula overflow well structure.

Background

The water storage tank is a water storage facility which is built by artificial materials and has an anti-seepage effect, and is an important rainwater accumulation important engineering facility. The shortage of fresh water resources, the water pollution and the ecological deterioration restrict the social and economic development to a certain extent, and the impounding reservoir is used as a water-saving system with low cost, so that the shortage of water resources is effectively relieved, and the problems of urban flood control and drainage are solved. And the overflow well of cistern is used for controlling the maximum water level in pond, prevents that the overflow water from influencing, and if the overflow well goes wrong, leads to the cistern function to receive the influence easily.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art's defect and not enough, provide a cistern overflow weir formula spillway well structure, this structure cushions the rivers of warning pipe through the overflow weir, and the double-chamber reduces drainage system pressure in the biggest water level in control pond, can inspect the spillway well water yield condition at any time through the glass steel caping simultaneously.

In order to achieve the above object, the utility model adopts the following technical scheme: a reservoir overflow weir type overflow well structure comprises a well wall, an overflow weir, an overflow pipe, a drain pipe, a sleeve and a cover top; the well wall is a rectangular reinforced concrete enclosure structure, and a concrete cushion is built on the bottom surface of the well wall; an overflow weir is built in the middle of the bottom surface of the well wall, the overflow weir divides the internal space of the well wall into two chambers with communicated tops, and the top surface of the overflow weir inclines downwards from one side to the other side; the well wall is provided with through holes at two sides of the overflow weir, an overflow pipe penetrates through the through hole opposite to the side with the high top surface of the overflow weir, and the end part of one end of the overflow pipe in the well wall is connected with a layer of steel wire mesh attached to the pipe end through a steel hoop and a bolt; a drain pipe penetrates through the well wall at a position symmetrical to the overflow pipe, sleeves are arranged between the outer walls of the overflow pipe and the drain pipe and the well wall, and a water stop ring is arranged in the well wall; the well wall top cover is provided with a cover top which is made of glass fiber reinforced plastic.

Preferably, the distance between the top surface of the overflow weir and the bottom surface of the cover top is not less than 500 mm.

Preferably, the distance between the overflow pipe and the drain pipe and the bottom surface of the well wall is not less than 200 mm.

The utility model has the advantages that: the structure buffers the water flow of the overflow pipe through the overflow weir, the pressure of the drainage system is reduced when the double cavities control the maximum water level of the pool, and meanwhile, the water quantity condition of the overflow well can be checked at any time through the glass fiber reinforced plastic cover top.

Drawings

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention.

Fig. 1 is a schematic diagram of a reservoir overflow well structure, and fig. 2 is a schematic diagram of a side-view cross-sectional structure.

Wherein: the structure comprises a well wall 1, a concrete cushion 11, an overflow weir 2, an overflow pipe 3, a steel wire mesh 31, a drain pipe 4, a sleeve 5 and a cover top 6.

Detailed Description
