Technical Field
The utility model belongs to the technical field of the river course is dredged, concretely relates to fabricated support structure is dredged to coastal city drainage river course.
Background
The urban river course is an important component of a river network water system and has multiple functions of flood control, flood drainage, shipping and the like, and in the long-term flood drainage and flood drainage process of the river course, water impurities and silt are continuously precipitated to cause serious river course silting, the river bed is continuously raised, the stability of the bank slope of the existing river course is reduced, the ecological environment of the river course is damaged, the flood drainage and flood drainage safety of the river course is seriously influenced, and the normal production and life of residents on two sides of the river bank are threatened. Dredging the river channel, effectively removing river bottom sludge, improving flood discharge and waterlogging discharge capacity of the river channel, and being an effective method for treating river channel siltation.
The urban river dredging technology mainly comprises a drainage dredging technology. The draining and dredging technology is that before sludge in a river channel is cleaned, water in the river channel is drained, then the sludge in the river channel is dug out by a dry digging method and an excavator and stacked in a proper place, and the sludge can be timely transported away by using a muck truck under the condition. When dredging a river channel, the basic appearance of the river channel is kept, and the stability and the safety of buildings near two sides of a river bank in the construction process are ensured. The city river course is peripheral more buildings, and the building has applyed relatively great load to the river course bank slope, will fully guarantee the stability of bank slope and just need carry out effectual strut to it, and the mode of strutting needs select according to the actual conditions of bank slope. However, bank slopes on two sides of an urban river are often steep, dry stone protective surfaces are mostly adopted, and instability and damage are very easy to occur if support measures are not adopted in the dredging process.
