The invention relates to the technical field of river regulation, in particular to a throwing and filling structure system and a working method.
Background
In the engineering for renovating the river channel of the bridge, the water depth of a construction area is 15-30 m, the water flow velocity in the construction period is 0.5-1.5 m/s, the slope of a bank slope is designed to be 1:6, the allowable deviation of slope excavation is +/-250 mm, and a large cutter suction dredger is adopted for dredging the slope; the soil quality is mainly silt and fine sand. The bank slope protective structure mainly comprises 3 layers of 125kg geotextile bag reverse filter layers and 90cm thick stone protection layers, and the foundation trench protective structure comprises 5 layers of 800kg geotextile bag protection layers. The geotextile bags adopt a continuous loose-throwing mode, wherein 1700 thousands of 125kg geotextile bags and 400 ten thousands of 800kg geotextile bags are adopted. The minimum thickness of the throwing filling quality requirement of the geobags meets three layers of 125kg geobags or 5 layers of 800kg geobags, the allowable thickness of the 5 layers of 800kg geobags is 2.0-2.5 m, the allowable thickness of the 3 layers of 125kg geobags is 0.5-0.75 m, the maximum thickness cannot exceed 150% of the designed layer thickness, and the throwing filling precision requirement is extremely high.
Since the start of the geotextile bag throwing filling construction, the Bengal Padema river regulation project always adopts a flat barge as a construction platform, four anchors are used as a positioning basis, positioning is carried out by a GPS, and the throwing filling process is a deck fixed-point stepping throwing filling method, so that the underwater drift and dispersion are very large due to the influence of factors such as water flow, deep water level and different water entering postures of geotextile bags in a construction area, the flatness tolerance of the geotextile bags after throwing filling is large, the unevenness is large, the slope formed after throwing filling is large, the labor intensity is high, the safety is poor, the construction efficiency is low, and the throwing filling process and the throwing filling result cannot be accepted by owners and are recognized by supervision, and the following brief description is given:
the geotextile bags have low throwing and filling precision, and the thrown and filled area has the problem of too high or too low thickness. The earth bag throwing and filling uses a flat barge as a construction platform, dozens of earth bags are thrown and filled into water at one side of the barge according to the measured fixed point position and the required throwing and filling layer number, and then a four-anchor positioning winch is adopted for stepping and throwing and filling the next round; however, when the geotextile bags enter water, the geotextile bags are influenced by water flow in a construction area and turbulence of the geotextile bags impacting the water surface, and the water level in the construction area is relatively deep, so that the geotextile bags are drifted after water enters and are difficult to fall to a preset riverbed throwing and filling place, the drift has relatively high randomness, the final throwing and falling point of the geotextile bags after water enters cannot be controlled, and finally, the thickness of the geotextile bag layers in the throwing and filling area cannot meet the specification requirements (is too high or too low). Supervision requirement: the throwing and filling precision does not approve the next working procedure or the construction of a working face under the condition that the throwing and filling precision does not meet the requirements of technical specifications; removing the filling material with a thickness exceeding a certain thickness, and performing additional polishing if the thickness is not met; the work difficulty of the super-thick removal is larger, and when the supplement and throwing are carried out again, the supplement and throwing geotextile bags are also influenced, so that the geotextile bags are difficult to fall to the low points, and the supplement and throwing effect cannot be achieved. Resulting in repeated and inefficient operation.
