云南省第八建筑工程公司研制的推拉式养护罩,用于长线台座预应力构件太阳能养护。将长线台座分成东西两段。构件浇注,养护两段流水作业。推拉式养护罩做成半段长,养护时随拉模在两段场地往返移动。为了实现机械化,制成自行铺设黑塑料薄膜小车。小车挂在由卷扬机牵行的成型拉模后端。随拉模行驶,小车上的滚筒转动,将黑
The push-pull curing hood developed by the No. 8 Construction Engineering Company of Yunnan Province is used for solar energy maintenance of long-term pedestal prestressed components. The long-term pedestal is divided into two sections. Pouring of components, conservation of two-stage flow operations. The push-pull type nursing cover is made into a half-length and is moved back and forth with the pull mold in two sections during maintenance. In order to achieve mechanization, self-made black plastic film carts were made. The trolley is hung on the rear end of a forming die pulled by a winch. With the die driving, the drum on the car turns and will turn black
