winter install solar street lamps need to pay attention to? Winter construction of concrete engineering should make preparations for winter construction organization plan and in advance of the materials and facilities should be snow, anti-freezing measures in advance. During winter construction, the use of Portland cement and ordinary Portland cement mixing of concrete compressive strength in hangzhou amounted to 40% of design strength and shall not be less than 5 MPa, not cold. When winter construction, fire prevention, freeze protection should be established, prevent gas poisoning and other security measures.

when the concrete mixed with air-entraining agent, additive, such as high water reducing agent, in order to improve the concrete hangzhou frozen. Mixing temperature of concrete in all kinds of materials should satisfy the temperature needed for concrete mixing after mixing synthesis. Winter mixing concrete aggregate shall not with lumps of ice and snow and freezing, strictly control the coagulation soil mixture ratio, and slump; Should be flush with hot water before feeding mixer, LED street lamp, feeding order: first aggregates and water mixing, when adding cement mixing stirring time should be a normal temperature prolong time by 50%. Concrete mixing material of the machine temperature should not be lower than l0 ℃, into the mold temperature is not less than 5 & rsquo; C,

transportation and casting of concrete technical requirements: concrete transportation time should be shortened as much as possible, to transport the container coagulation soil should be heat preservation measures. Before concrete pouring should clear the snow and ice on the template, steel or corrupt scale, prepare molding curing temperature, using the regenerative method shall not be lower than lot; Steam method shall be not less than 50 c; Thin structure shall not be less than 8 c.
