绍兴市西郭水厂西迁工程核心项目一一取水泵房,位于离岸边140米的青甸湖中,建筑面积780平方米,二层钢筋混凝土框架结构,建筑物高度露出常年水位3.80米以上15米,由单桩承载力350千牛顿的105根40×40厘米预制方桩将泵房建筑物托出水面。泵房桩承台底标高为2.75米,即在水面下1.05米处。按常规做法为土筑围堰或钢板锁口桩密封围堰,但从时间、造价和土来源等方而都不允许。故尝试采用密封防水木模浇捣混凝土的新方法,
One of the core projects of the west migration project of Xiguo Water Plant in Shaoxing City is a water pumping station. It is located in Qingdian Lake, 140 meters away from the bank. It has a building area of 780 square meters and a two-story reinforced concrete frame structure. The height of the building reveals a constant water level of 3.80 meters. For the above 15 meters, 105 40*40 centimeter prefabricated square piles with a single pile capacity of 350 kN were used to lift the pump room buildings out of the water. The bottom elevation of pump pile caps is 2.75 meters, which is 1.05 meters below the water surface. According to conventional practice, earth cofferdams or steel lock piles are used to seal cofferdams, but they are not allowed from time, cost, and source of earth. Therefore, a new method of pouring concrete with sealed waterproof wooden molds was tried.
