Anti-ice-pushing method for protecting auxiliary steel pipe of reservoir protection slope water measuring facility

Abstract

The invention discloses an anti-ice-pushing method for protecting an auxiliary steel pipe of a reservoir protection slope water measuring facility, a concrete triangular force release block is poured on a reservoir protection slope with the steel pipe as the center, the end face of the triangular force release block is an isosceles triangle, the bottom face is a rectangle, and the bottom is laid on the reservoir protection slope; a rectangular sliding steel plate consistent with the surface formed by the reservoir protection slope and the triangular force release block in shape is manufactured, the bottom face of the rectangular sliding steel plate is polished, and a plurality of steel bars parallel to the bottom end face of the rectangular sliding steel plate are welded to the top face of the rectangular sliding steel plate; the rectangular sliding steel plate covers the surfaces of the protection slope and the triangular force release block and is suspended and fixed to the top of the protection slope in a sliding mode, the bottom end of the rectangular sliding steel plate is parallel to the bottom end of the triangular force release block, and the center line is located over the ridge line of the triangular force release block. The method is used for protecting water measuring facilities on water conservancy project protection slopes such as reservoirs in cold regions and preventing sedimentation from affecting measuring results.

Description

technical field [0001] The invention relates to the field of protection of water conservancy facilities, in particular to an anti-icing push method for protecting auxiliary steel pipes for slope protection and water measuring facilities in reservoirs. Background technique [0002] The water conservancy project is the center and soul of the water conservancy undertaking, and its status as the lifeline of the national economy and the basic industry has become more and more prominent. It has played a huge role in this aspect and produced obvious social and economic benefits. At the same time, it is also related to the safety of life and property of the downstream people and sustainable economic development. It is a major event involving public safety, social stability and development. [0003] According to the 2018 National Water Conservancy Development Statistical Bulletin, my country has built 98,822 reservoirs of various types, with a total storage capacity of 95.3 billion m...

Problems solved by technology

At the same time, some reservoirs have serious siltation and the pressure-type water level gauge hole is easily blocked. Taking a reservoir in Xinjiang as an example, in order to accurately measure the reservoir capacity, the pressure-type liquid level gauge is used to measure the water level in the reservoir area, but the conventional anti-collision 1. After the flood discharge is protected by steel pipes, it is affected by ice push in winter, causing repeated bending of steel pipes, damage to power supply and communication cables, and changes in the position of liquid level gauges. At the same time, affected by a large amount of sediment in the water, some liquid level gauges Measuring hole traffic jams, resulting in unreliable measured values

[0006] New water conservancy projects may prevent the impact of ice push by burying water measuring facilities under hydraulic structures. However, there are few new reservoir projects in my country, and the water storage is huge. and an important obstacle to the automatic promotion of reservoir water measurement in northern areas, which seriously restricts the development of water conservancy engineering information in these areas
