Aforesaid horizontal rock-bolt length is 2～3m, gos deep into the rock 1.5～2.5m of described energy dissipating anti-scour wall both sides, exposes 0.5m, an array pitch 2m; Aforementioned vertical rock-bolt length is 5～7m, gos deep into rock 4～6m, exposes 1.0m, an array pitch 2m.Can guarantee that like this anchor pole plays effective reinforcement effect.
Embedded energy dissipating erosion control structure of the present utility model may further comprise the steps when construction:
At first carry out the construction that preceding anchor pole and consolidation grouting are dug in sidewall basis, riverbed earlier before carrying out energy dissipating anti-scour wall hole groove foundation excavation, the consolidation grouting hole depth is gone into fresh basement rock;
Carry out energy dissipating anti-scour wall hole groove foundation excavation according to energy dissipating anti-scour wall size again; Deep-cut to the 2～3m below the degree of depth of hole that dashes that estimates in river course, energy dissipating erosion control district two bank slopes bottom during excavation, to guarantee buried depth, prevent that the energy dissipating anti-scour wall from caving in or slippage under earial drainage impacts.
Finish the groove basis supporting of energy dissipating anti-scour wall hole then; Wherein groove digs the employing bolt-spary supports, and all the other excavations adopt bolt support, and pneumatically placed concrete is the C25 steel fibrous concrete, thick 10cm.
Finish the concreting of energy dissipating anti-scour wall according to conventional casting craft at last, and establish constuction joint every 10～20m on the energy dissipating anti-scour wall, 20～40m establishes the shrinkage joint, joins distributing bar on energy dissipating anti-scour wall top layer.The energy dissipating anti-scour wall wall thickness 1～3m that forms forms whole force structure thereby wall pushes up and concrete revetment joins, and with washing away of opposing current, guarantees energy dissipating erosion control Stability Analysis of Structures.
The utility model adopts embedded energy dissipating erosion control structure, energy dissipating anti-scour wall and bottom basement rock are combined into overall structure by anchor pole and consolidation grouting, energy dissipating anti-scour wall top joins with concrete revetment and forms whole force structure, with washing away of opposing current, guarantees energy dissipating erosion control Stability Analysis of Structures.During following flood discharge water, the opposing current scour, bank slope can not destroy, this energy dissipating erosion control structure does not need to remove the whole covering layer in riverbed, engineering quantity is little, and concrete construction is convenient, guarantees concrete pouring quality, save investment, guaranteed the structural safety in flood-discharge energy-dissipating erosion control district during following flood discharge water.
