Reverse clay inclined core wall anti-seepage cofferdam structure and construction method
The invention discloses a reverse clay inclined core wall anti-seepage cofferdam structure and a construction method, and relates to the technical field of hydraulic engineering. The reverse clay inclined core wall anti-seepage cofferdam structure comprises a sand gravel covering layer covering a bed rock layer; a closure berm formed by sand gravel is constructed on the sand gravel covering layer;a rock block layer playing a role in protection and seepage prevention is laid on an upstream side of the closure berm; a water intercepting groove connected with the bed rock layer is dug in the sand gravel covering layer on a downstream side of the closure berm; the downstream side of the closure berm is covered with a clay anti-seepage layer; the lower edge of the clay anti-seepage layer extends into the water intercepting groove and makes contact with the bed rock layer; and the side, away from the closure berm, of the clay anti-seepage layer is covered with a downstream side sand gravellayer. According to the method, control construction is conducted on the basis of the cofferdam structure, and on the whole, the problems that an existing cofferdam structure is relatively long in construction period, relatively high in manufacturing cost and not suitable for seepage prevention of a sand gravel riverbed containing few fine particles can be solved through implementation of the method.
本发明公开了一种反向粘土斜心墙防渗围堰结构及施工方法，涉及水利工程技术领域，该结构包括覆盖于基岩层上的砂砾石覆盖层，砂砾石覆盖层上构筑有由砂砾石形成的截流戗堤，截流戗堤的迎水一侧铺设有起防护防渗作用的块石层，截流戗堤背水一侧的砂砾石覆盖层上开挖有与基岩层相接的截水槽，截流戗堤的背水一侧覆盖有粘土防渗层，粘土防渗层的下沿延伸至截水槽内并与基岩层接触，粘土防渗层远离截流戗堤的一侧覆盖有背水侧砂砾石层；该方法基于该围堰结构进行控制施工，总体而言，通过实施本发明能够克服现有围堰结构施工工期相对较长、造价成本相对较高且不适应于含细颗粒较少的砂砾石河床进行防渗的问题。
