Cofferdam construction scheme of river training project
This data is the cofferdam construction scheme of river training project, 9 pages in total, in the form of word. Project overview: The river channel of Team 6 of Zhangjiahe River Regulation Section of the Project is about 160m long and 16m wide, and the balance weight type flood embankment+green slope protection is adopted on both banks to achieve flood control effect. Before the river construction, the river flow shall be diverted, and the excavation of foundation pit and retaining wall shall be carried out without water. The cofferdams are filled with earth and stone materials. The internal and external side slopes of the cofferdams are 1:1.3. The top of the cofferdams is 3.0m wide. The upstream surface is impervious with sandbags. In addition, it is necessary to expand the excavation of the riverbed diversion to form a new channel, with the depth of about 2~3m, the width of the narrowest part of about 5m, and the excavation length of about 160m. The method of cofferdam is to add sandbags on the outer upstream surface. If the leakage can not be well treated and the flow is too large, it is necessary to add a catch basin at the downstream of the cofferdam, increase the input of drainage equipment, increase the drainage volume, and forcibly drain the leakage water to ensure that the foundation pit is concreted in a dry place.

Construction Scheme of Timber Pile Cofferdam for River Training Works
Project overview: This project includes a new sluice, Xinkai River and old river regulation works. Wooden pile cofferdam is adopted. According to the survey, the water depth of the river channel at the cofferdam is about 2m. According to the site conditions, 6 m long larch logs with a diameter of 35~1000px are driven as piles for the cofferdam. Cofferdam should be started from both ends, and the dam body should be exposed to the water surface in a sudden attack, and then gradually extended until closed. Try not to interrupt so as not to cause too much mud to affect the strength of the cofferdam. The filling inside and outside the pile line must be carried out synchronously, and the height difference between inside and outside shall not exceed 1m. The cofferdam must be filled to the design section before pumping.
