Construction method for gabion filling fine aggregate concrete river channel bottom protection
The invention discloses a gabion pouring fine aggregate concrete river channel bottom protection construction method. The problems that a river channel is high in cost and inconvenient to maintain can be effectively solved. The gabion net is arranged on the geotechnical cloth to be assembled and formed; during assembly, the separation net and the net body intersect at 90 degrees, and a rectangular net cage group or a net cage is formed through binding; the spacing net is spirally connected with the net body frame lines, the binding wires are tightly combined with the net pieces and are closed and connected along the boundary, and the interface or the end is tightened; the spacing net and the four corners of the net body, the four corners of the adjacent net cages and the net faces of the adjacent net cages are bound through binding wires in a double-strand mode, the binding distance at the intersecting position is 200-250 mm, and no less than two positions of the net faces of the adjacent net cages are arranged per square meter. The method has the beneficial effects that the gabion with a certain thickness is laid at the bottom of the river channel, and fine aggregate concrete is poured, so that river scouring is effectively prevented or slowed down from developing to the top of the inverted siphon, and the purposes of high foundation deformation adaptability, simple construction process and reduction of channel operation and maintenance cost are achieved.
本发明公开了一种格宾石笼灌注细石混凝土河道护底施工方法，能够有效解决河道成本高且不便于维护的问题；格宾网布置在土工布进行拼装成型；拼装时间隔网与网身成90°相交，经绑扎形成长方形网箱组或网箱；间隔网与网身框线采用螺旋连接，扎丝与网片结合紧密，沿边界封闭联结，接口或端头拧紧；间隔网与网身四角、相邻网箱四角、相邻网箱网面均采用扎丝双股绑扎，交线处绑扎间距200～250mm、相邻网箱网面每平米不少于两处。有益效果：通河道底部铺设一定厚度的格宾石笼并灌注细石混凝土，有效的防止或减缓河流冲刷发展到倒虹吸顶部，达到了适应地基变形能力强，施工工艺简单、减少渠道运行维护费用的目的。
