Background
At present, a cushion layer sand-free concrete lining of a dam or a reservoir basin mainly adopts a longitudinal drawing die method, and concrete is continuously poured from bottom to top along side dies by utilizing a winch traction die body. In order to resist the lateral pressure of concrete and prevent the die body from floating upwards, a certain amount of counter weights are required to be placed on the die body. Although the technology of the longitudinal drawing method is more mature, the construction speed and quality are also guaranteed; however, the problems are also very remarkable, and the following aspects are mainly presented:
1. the longitudinal die drawing method mainly depends on the slope chute laid on the slope to automatically slide and convey concrete, and besides the fact that the chute is frequently installed and detached manually is complicated, more importantly, the concrete conveying restriction factors are more, and the quality is unstable. Meanwhile, the manual work is matched with the distributing groove for distributing materials, the workload of warehousing and leveling is large, and the construction speed is restricted to a certain extent.
2. The longitudinal drawing die method completely depends on self weight and counterweight to resist the lateral pressure of concrete to resist floating, so that the reliability is poor and the uncertainty is high; the phenomenon of wavy fluctuation and unevenness easily occurs in the sliding and lifting process, so that the thickness and the flatness of the panel are difficult to effectively control, the repairing workload is large, and the surface quality of the concrete is influenced to a certain extent.
3. The longitudinal die drawing method generally adopts a double-winch traction die body, so that synchronous lifting is difficult to realize, the phenomena of uneven sliding lifting, inconsistent demoulding strength and the like caused by elastic stretching of a steel wire rope can not be overcome, and even the phenomena of cracking, flowing and the like occur, thereby increasing the repairing workload and influencing the engineering quality.
In summary, the design provides a construction device which has a relatively simple structure and convenient installation and movement, can effectively overcome the defects, improve the lining efficiency, improve the concrete quality of the panel, simplify the construction process and optimize the labor organization, and particularly a construction method for a bedding board with a medium slope length, which is a problem to be solved by engineering personnel in the field.
