Problems solved by technology

A large number of experimental studies and engineering examples show that due to the large facing surface and high center of gravity of the solid concrete tetrahedron and hexahedron in the water, the resistance to the water flow is obvious, the dynamic water action lasts for a long time, and the stability is poor. Cage strings also have the problem of poor material stability and loss. Therefore, the existing solid concrete tetrahedron, hexahedron, and reinforced gabion strings are not ideal in the difficult period of closure. Optimized for better interception

Abstract

The invention belongs to the field of river closure of hydraulic engineering, and provides an improved tetrahedron throwing material for closure work. The material comprises a tetrahedron body; through holes communicated with each other and penetrating through each surface of the tetrahedron body are formed in the tetrahedron body; and the density of the tetrahedron body is 2400-3700 kg / m3. Compared with a traditional solid regular tetrahedron throwing material, the improved tetrahedron throwing material is lower in suffered water meeting resistance, higher in stability in water currents and lower in loss rate in the water currents, and can reduce the closure difficulty.

Description

technical field [0001] The invention belongs to the field of river interception in water conservancy projects, in particular to an improved tetrahedron throwing material used in interception projects. Background technique [0002] The interception project is to cut off the water flow in the original river channel at the gap (dragon mouth) reserved by the river blocking structure in the shortest time, so that the water flow in the river channel can be vented or stored in other places to form a foundation pit for dry land construction. A key issue in the construction of water conservancy projects, it is a control item that affects the construction progress. During the process of intercepting the water flow, the turbulence of the river channel, the underwater topography and the shape of the dike will change continuously with the occupation period, which will easily lead to the loss of interception materials and the collapse of the dike, which will increase the difficulty of int...
