1 前言在我省重点工程白龟山水库除险加固工程的拦河坝段的施工中,上游坝坡采用150_#混凝土预制块进行护坡加固。总护坡面积3.68万m~2;混凝土块预制量1.47万m~3,为保证1999年的汛期拦坝安全度汛,要求在1999年5月底前,预制块护坡必须铺砌完毕;达到原来的度汛标准。这样预制块工作必须在1999年4月底完成,预制工作时间6个月中还有12、1、2月份气温较低,难以实行自然养护。只有11、3、4月份可进行常态的自然条件养护预制,月预制量达到了4900m~3(日平均强度
1 Preface In the construction of the dam section of the reinforcement project of Baiguishan Reservoir in the key project of our province, the upstream dam slope adopts the 150_ # concrete prefabricated block to reinforce the slope. The total slope protection area is 36,800 m 2 and the concrete block production volume is 14,700 m 3. In order to ensure the flood control dam safety in flood season in 1999, it is required that the precast block slope protection be completed before the end of May 1999; Flood standard. Such prefabricated work must be completed by the end of April 1999, with prefabricated working hours of 6 months and low temperatures in December, January and February, making it difficult to implement natural conservation. Only in November, April and April can be normal maintenance of natural conditions, the monthly pre-production reached 4900m ~ 3 (average daily intensity
