Water stop cofferdam structure and construction method thereof
The invention discloses a water stop cofferdam structure. The structure comprises a cofferdam main body and is characterized in that the cofferdam main body is formed by filling clay, and fir piles and a waterproof geotextile layer are arranged in the cofferdam main body. A construction method of the water stop cofferdam structure comprises the following steps that A, sundries at the bottom of thecofferdam main body are removed; B, two rows of the fir piles are inserted forwards by a certain distance; C, a waterproof geotextile is arranged on one side of the upstream face of each fir pile; D,clay is filled along a slope from a weir head exposed out of the water surface, ing the inner side and the outer side of each fir pile is symmetrically and uniformly filled, and vibration is performed to ensure the filling compactness; E, the fir piles and the waterproof geotextiles are constructed synchronously, the construction distance is larger than the clay filling length, and enough lap joint length between adjacent waterproof geotextiles is guaranteed; and F, the aforesaid steps are repeated until the cofferdam main body reaches an opposite bank, and filling of the cofferdam main bodyis completed.
本发明公开了一种止水围堰结构，包括围堰主体，其特征在于：所述围堰主体由粘土填筑而成，所述围堰主体中设有杉木桩和防水土工织物层，所述止水围堰结构的施工方法，包括如下步骤：A、清除围堰主体底杂物，B、向前插打一段距离的两排杉木桩；C、在杉木桩的迎水面一侧设置防水土工织物；D、自露出水面堰头顺坡填筑粘土，杉木桩内外侧对称均匀填筑，并进行振捣，保证填筑的密实性；E、杉木桩与防水土工织物同步进行施工，施工距离每段长于粘土填筑长度，保证相邻防水土工织物之间有足够的搭接长度；F、重复上述步骤，直至对岸，完成围堰主体的填筑。
