The method of using siphon construction diversion pipe to make the construction conditions of river dry land

Abstract

The invention provides a method for using a siphon-type construction diversion pipe to manufacture dry river construction conditions, the steps are as follows: record the river area where the construction conditions for river dry land are to be manufactured as the construction dry area, and the construction dry area is located at the water retaining area of ​​the river Downstream of the building; determine the backwater area downstream of the construction dry area, and the back water area is adjacent to the construction dry area; install a siphon construction at the water-retaining building to transport the water upstream of the water-retaining building to the downstream of the backwater area Diversion pipe: Create a vacuum condition for the siphon construction diversion pipe to transport the water in front of the water-retaining building to the downstream of the backwater area through the siphon construction diversion pipe. When the water in the target area flows out of the target area, the construction The dry area forms the construction conditions of river dry land. The method can significantly reduce the project investment, simplify the manufacturing operation of the construction conditions of the river dry land, avoid the hidden danger of flooding, and has the characteristics of being more environmentally friendly.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and relates to a method for using a siphon-type construction diversion pipe to manufacture construction conditions for river dry land, and is suitable for engineering situations where construction conditions for river dry land need to be manufactured downstream of river channel water retaining structures. Background technique [0002] When constructing on the river, the conventional solution is to build the construction cofferdam to create the dry land conditions required for construction, and then remove the construction cofferdam after the project is completed. Construction of cofferdam construction requires high investment and long construction period, which often becomes a restrictive factor for engineering construction in urban rivers. After the completion of the construction, cleaning up the materials used to build the construction cofferdam, such as waste rocks and waste residu...

Problems solved by technology

[0003] In view of the existing technology, the construction and demolition cost is too high, the construction period is long, and the river channel is occupied by waste residue to create the construction conditions of the dry land of the river channel by building the construction cofferdam. Insufficient influence, the present invention provides a kind of method that utilizes siphon type construction diversion pipe to manufacture the construction condition of dry river course, in order to effectively reduce engineering investment, simplify the manufacturing method of construction condition of dry river course, at the same time avoid causing flood safety hidden danger, Manufacture the construction conditions of river dry land in a more environmentally friendly way to avoid adverse effects on river water quality and river bank environment
