Riverway truss type anchor pulling anti-floating device and construction method thereof

Abstract

The invention relates to a riverway truss type anchor pulling anti-floating device. One or more trusses is / are distributed in the riverway vertical water flow direction; each truss comprises concrete piers, concrete foundation blocks, anchor bars, a steel wire rope and a steel tube truss composed of steel tubes distributed in different space direction; two concrete piers are arranged in each riverway truss type anchor pulling anti-floating device, the concrete piers are distributed on the upstream side in a riverway in the direction perpendicular to the water flow at a certain distance intervals, the anchor bars are embedded in the concrete piers, the concrete foundation block are distributed on the downstream side of the concrete piers in a matrix shape, and the bottom ends of parts of steel tubes forming the steel tube truss are embedded into the concrete foundation blocks; one ends of the steel wire ropes are connected with the anchor bars, and the other ends of the steel wire ropes are connected with the steel tubes. The riverway truss type anchor pulling anti-floating device can be used for construction in complex terrain, and has the beneficial effects of being convenient to construct, environment-friendly, practical, wide, good in floating object blocking effect, safe and economical.

Description

technical field [0001] The invention relates to a river course anti-drift device and a construction method thereof for water conservancy projects, in particular to a river channel truss-type anti-drift device for water conservancy projects during flood seasons and a construction method thereof. Background technique [0002] During the construction of the water conservancy barrage project, due to the closure of the river channel, the diversion tunnel begins to pass through the water. When only the diversion tunnel passes through the water, it is difficult to pass through the upstream floating objects, shrubs and groups of haystacks due to the small cross-section of the water. And construction waste, resulting in the blockage of the diversion tunnel, raising the water level of the river, seriously affecting the safety of the river-blocking buildings during the flood season. Therefore, the way of blocking floating nets is generally adopted to intercept floating objects. During...

Problems solved by technology

Therefore, the structural design of the floating barrage is complex and the construction cost is high. It is necessary to use a simple support structure as much as possible to reduce the construction cost under the premise of satisfying the engineering functions.
