Abstract

The invention provides a spur dike head protection device which comprises a spur dike concrete body and multiple anchor rods arranged on a river bottom foundation. The two sides of the head of the spur dike body are provided with first wavy steel plates. The first wavy steel plates on the two sides of the head of the spur dike body are connected through an arc second wavy plate. The second wavy plate is provided with a second bolt hole, a second bolt is arranged in the second bolt hole, and an arc rubber plate is fixedly arranged on the second bolt. By means of the protection device arranged on the head of a spur dike and an anchor system of the river bed foundation, the stability of the whole spur dike is improved, and use and maintenance of the spur dike are facilitated.

Description

technical field [0001] The invention relates to a water conservancy protection device, in particular to a spur head protection device. Background technique [0002] The spur dam is a commonly used dam structure in the field of water conservancy. Its dam head goes deep into the river, and the dam body and the bank form a T-shaped structure. This dam structure plays an important role in preventing the erosion of the bank and is widely used in rivers in our country. use. [0003] Since the head of the spur dike is deep into the river, it is easily washed by the river. Most of the existing protective measures are to strengthen the head body of the spur dike, configure steel bars, and increase the strength of concrete, etc., which have certain limitations. Moreover, due to the poor anchoring performance of the spur dike and the foundation river bed, its ability to resist water flow is limited, the overall stability of the spur dike is affected, and it is prone to damage. Conte...
