克拉玛依炼油厂污水场浮选池为高抗冻大型钢筋混凝土敞口水池,池长21.45m,宽20.3m,深4.75m,池壁厚40m,总蓄水量2000m~3,由于工艺和保温需要池内有三道隔墙,池顶盖混凝土槽板施工拆模后发现在池壁0.8～1m高的断面上,宽度20cm范围内,漏振、蜂窝、露筋相当严重,池壁内外松散,深度占池壁厚度1.2-2.3的洞达39处,通洞共6处,最大通洞长55cm,宽3cm采用干硬性细石混凝土用人工捣固修补,经试水,修补部分均未有漏水现象,从1985年9月进水至今,经过3个冬季(最低温度-40C)的使用,修补部分完好无损,达到抗冻及补漏要求。
The flotation cell of the Karamay refinery wastewater treatment plant is a large anti-freeze large-scale reinforced concrete open pond. The pool length is 21.45m, width is 20.3m, depth is 4.75m, the wall thickness is 40m, and the total storage capacity is 2000m~3. Due to the process and insulation requirements There are three partition walls in the pool. After the demolishing of the concrete deck slab of the pool top, it is found that the height of the pool wall is 0.8 to 1m high and the width is within 20cm. The leakage vibration, honeycomb and exposed tendon are quite serious. The inside and outside of the pool wall are loose and the depth accounts for There are 39 holes with a wall thickness of 1.2-2.3, 6 holes, a maximum hole length of 55cm, and a width of 3cm. The dry hard and fine stone concrete is manually tamped and repaired. After testing the water, none of the repaired parts leaked. From 1985 In September of this year, after entering the water, after 3 winters (minimum temperature -40C), the repaired parts are in good condition and have achieved anti-freeze and leak-filling requirements.
