Abstract

The invention discloses an overflow pool for a culvert, which comprises box culverts and connecting pools, wherein at least two box culverts are arranged, all the box culverts are buried underground side by side, and each box culvert is independently communicated with the connecting pool through an independent overflow blind culvert. All overflow implications are not communicated with each other and are located at the same height. The two ends of the box culvert are connected with water delivery pipelines, and water stops are arranged at the contact positions of the outer walls of the water delivery pipelines and the box culvert. The box culvert is provided with a water inlet end and a water outlet end, wherein the water inlet end is provided with a water inlet hole, the box culvert is also provided with a vent hole, and the vent hole is connected with a vent pipe which is exposed out of the ground. The water flows in each box culvert are not mutually influenced when overflows, and water enters the side wall connecting pool through the overflow culvert and flows into the downstream river channel in a collecting way.

Description

Overflow pool for duct

Technical Field

The invention relates to the technical field of water conservancy, in particular to an overflow pool for a culvert.

Background

In the prior art, the culvert applied to water conservancy construction needs to be provided with an overflow pool, but the current culvert is generally a plurality of parallel box culverts buried underground together, each box culvert cannot realize independent control of overflow of each box culvert, and overflow water levels among the box culverts are mutually influenced.

Disclosure of Invention

The invention aims to provide an overflow pool for a culvert, water flows in each box culvert are not affected when overflowing, and water enters a side wall connecting pool through overflow culverts and flows into a downstream river channel in a collecting way.

In order to achieve the purpose, the overflow pool for the culvert adopts the following technical scheme that the overflow pool comprises box culverts and connecting pools, wherein at least two box culverts are arranged, all the box culverts are buried underground in parallel, each box culvert is provided with a water inlet end and a water outlet end, the water inlet end is provided with a water inlet hole, the box culverts are further provided with vent holes, and the vent holes are connected with vent pipes exposing the ground. Each box culvert is independently communicated with the connecting pond through an independent overflow culvert. All overflow implications are not communicated with each other and are located at the same height. The two ends of the box culvert are connected with water delivery pipelines, and water stops are arranged at the contact positions of the outer walls of the water delivery pipelines and the box culvert. The box culvert, the connecting pool and the overflow culvert are connected with each other to form an integrated forming structure.

Compared with the prior art, the invention has the following beneficial effects:

the overflow pool is in the form of a plurality of independent box culverts, and corresponds to a plurality of independent pipelines with the same number; the water flow in each box culvert is not affected when overflowing. The water enters the side wall connecting pool through overflow culverts and flows into the downstream river channel in a collecting way.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

As shown in fig. 1 to 5, the overflow pool for the culvert comprises box culverts and connecting pools, wherein at least two box culverts are arranged, all the box culverts are buried underground side by side, and each box culvert is respectively communicated with the connecting pool through separate overflow culverts. All overflow implications are not communicated with each other and are located at the same height. The two ends of the box culvert are a water inlet end and a water outlet end respectively, the water inlet end and the water outlet end are connected with a water conveying pipeline, and a water stop belt is arranged at the contact position between the outer wall of the water conveying pipeline and the box culvert. The box culvert water inlet end is provided with a manhole, and the box culvert is also provided with a vent hole which is connected with a vent pipe exposing the ground.

The box culverts may be arranged in parallel one by one, or may be arranged in the following embodiments.

For example, when the box culvert is less than or equal to three, the box culvert, the connecting pool and the overflow culvert are of an integrated structure.

For another example, when the number of the box culverts is four or more, the box culverts are two by two to form an integrated forming structure when the number of the box culverts is even, and the arrangement combination of 2+1 or 3+2+1 is odd.

Of course, the connecting pool and the overflow culvert can be formed with the next box culvert as an integral structure.

All the joints are provided with water stops at places where water flows need to pass.

When extreme working conditions occur at the downstream of the overflow pool or overhaul is needed, an overhaul valve (single pipeline or a plurality of pipelines) is closed, and at the moment, overflow occurs in the overflow pool. During overflow, water enters the side wall connecting pool through overflow culverts and flows into the downstream river channel in a collecting way.

In the description of the present invention, it should be understood that the terms "longitudinal," "transverse," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present invention, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
