Water area cofferdam construction method
The invention provides a water area cofferdam construction method, which relates to the technical field of cofferdam construction, and comprises the following steps: step 1, staking out in survey, setting a survey control point on the edge of a reservoir, frequently checking, ensuring the control accuracy, determining the control point, transferring to the shoreside of a construction area, driving a control point fixing pile, checking and calculating the elevation of the pile, and setting out the control point; in addition, a water level observation ruler is arranged on the water side, the scale of the water gauge is divided to centimeter, and the top elevation of the water gauge is measured and used for observing the daily water level condition; according to the method, a mixed-flow pump pumping and draining mode is adopted, so that the precipitation speed can be strictly controlled, the situation that the cofferdam and side slopes on the two sides of the cofferdam collapse due to the too high draining speed is prevented, operation is conducted according to the two-cloth-one-film technology, it is ensured that the cofferdam does not leak water in the cofferdam stacking and building process, and the safety during cofferdam construction is improved.
本发明提供一种水域围堰施工方法，涉及围堰施工技术领域，包括以下步骤：步骤一：测量放样，在水库边设置测量控制点，并经常校核，确保控制的准确性，确定好控制点，转测到施工区岸边，打控制点固定桩，并对该桩的高程进行校核计算，达到技术规范以内，作为施工高程控制点使用，另外，在水边打一水位观测尺，水尺分划刻度至厘米，测出水尺顶标高，用于观测每日水位情况；本发明中，采用混流泵抽排的方式：使降水速度能够受到严格控制，从而防止了围堰及两侧边坡因排水速度过快而产生坍坡的情况出现，按照‘二布一膜’工艺操作，使围堰堆筑过程中为确保围堰不漏水，提高了围堰施工时的安全性。
