[0002] In the process of constructing water conservancy projects in water areas (mostly referring to rivers with flowing water), in order to create dry land construction conditions, cofferdams are used to protect the foundation pit in the early stage, and the river water flow is directed to the downstream in a predetermined way to bypass the construction site. Construction diversion is a very important engineering measure unique to water conservancy project construction, especially the construction of dam projects. During the river diversion process, the water flow has a greater impact on the bends of the temporary diversion channel, which needs to be strengthened locally. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a temporary diversion mechanism for water conservancy project construction, including a dam, a filling soil foundation, a retaining embankment, a river channel, an arc-shaped flood discharge enclosure, a drainage channel, and a drainage pipe. A drainage channel is arranged on one side of the river channel, and an arc-shaped flood discharge enclosure is constructed at a right angle to the interface between the river channel and the drainage channel, and a drainage pipe is installed on the outside of the drainage channel.

[0005] Preferably, the arc-shaped flood discharge enclosure is composed of a drainage enclosure, a flood discharge frame and supporting columns. The flood discharge frame is installed on the inner side of the drainage enclosure plate body, and supporting columns are evenly spaced and fixedly installed on the outer side of the drainage enclosure arc top.

[0006] Preferably, the flood spillway frame is composed of a drainage hole, a drainage slope and an arc-shaped flood spillway slope top; the drainage slope and the arc-shaped flood spillway slope top are integrally cast and formed, and the drainage hole is punched on the drainage slope.

[0007] Preferably, the supporting column is composed of an outer bracket and a structural reinforcement column, and the structural reinforcement column is positioned and welded in the arc-shaped inner groove of the outer bracket.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The water flow hits the spillway frame and is diverted through the diversion slope before discharging through the arc-shaped top of the spillway slope. The flood discharge structure design of the water conservancy project is referred to to reduce the impact of the water flow on the arc-shaped corners of the flood discharge enclosure. The through-hole design of the diversion hole reduces the impact of the water flow on the spillway frame. The tangent point of the supporting column is installed at the top of the arc of the enclosure corner to provide structural support for the arc-shaped corner and ensure the stability of the drainage channel.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1-Figure 4 As shown, a temporary diversion mechanism for water conservancy project construction includes a dam 1, a filling soil foundation 2, a retaining dike 3, a river channel 4, a curved flood discharge retaining dike 5, a diversion channel 6, and a diversion pipe 7. The filling soil foundation 2 and the retaining dike 3 are combined inside the river channel 4 of the dam 1, a diversion channel 6 is arranged on one side of the river channel 4, a curved flood discharge retaining dike 5 is constructed at a right angle to the interface between the river channel and the diversion channel 6, and a drainage pipe 7 is installed on the outside of the diversion channel 6.

[0017] The arc-shaped flood discharge enclosure 5 is composed of a drainage enclosure 8, a flood discharge frame 9 and supporting columns 10. The flood discharge frame 9 is installed on the inner side of the drainage enclosure 8 plate body, and the supporting columns 10 are evenly spaced and fixedly installed on the outer side of the arc top of the drainage enclosure 8. The drainage enclosure 8 is an integrally cast design, and the flood discharge frame 9 is designed with reference to the flood discharge structure of the water conservancy project, which reduces the impact of water flow on the arc-shaped corners of the flood discharge enclosure.

[0018] The flood spillway frame 9 is composed of a drainage hole 11, a drainage slope 12 and an arc-shaped flood spillway slope top 13. The drainage slope 12 and the arc-shaped flood spillway slope top 13 are cast and formed in one piece. The drainage slope 12 is punched with drainage holes 11. Water flows impacting the flood spillway frame 9 are diverted through the drainage slope 12 and then rise up through the arc-shaped flood spillway slope top 13 to discharge. The through-hole design of the drainage hole 11 reduces the impact of water flow on the flood spillway frame 9.

[0019] The support column 10 is composed of an outer bracket 14 and a structural reinforcement column 15. The outer bracket 14 is positioned and welded with the structural reinforcement column 15 in the arc-shaped inner groove. The structural reinforcement column 15 serves as a structural support for the arc-shaped corner to ensure the stability of the drainage channel.

[0020] Specific usage: A temporary diversion mechanism for water conservancy project construction. This device is designed for the structural reinforcement design of temporary diversion channels for water conservancy project construction. After the river is diverted, the water flow impacts the arc-shaped flood discharge enclosure. The water flow impacts the flood discharge frame and is diverted through the diversion slope before discharging through the top of the arc-shaped flood discharge slope. With reference to the flood discharge structure design of the water conservancy project, the impact of the water flow on the arc-shaped corners of the flood discharge enclosure is reduced. The through-hole design of the drainage hole reduces the impact of the water flow on the flood discharge frame. The tangent point of the supporting column is installed at the top of the arc of the enclosure corner to provide structural support for the arc-shaped corner to ensure the stability of the drainage channel. The drainage pipeline is designed for secondary drainage.

[0021] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
