Description
Technical Field
The invention relates to a construction method of a cast-in-place deep arc wave wall based on a sliding formwork, belongs to the field of hydraulic engineering, and is suitable for construction of the deep arc wave wall.
Background
In order to overcome the adverse effect of wind wave climbing, it has become a common practice in hydraulic engineering to provide a wave wall on the upstream side of the river levee. The traditional wave wall pouring construction procedure comprises the steps of formwork erection, formwork supporting and reinforcing, formwork correction, formwork seam treatment, concrete pouring and formwork removal in a common combined steel-wood formwork mode. The conventional method has the disadvantages of large material consumption, large occupied working surface, poor template reinforcing quality, more template joints, weak rigidity and incapability of ensuring the concrete quality; particularly, one side of the wave-facing surface is positioned on a high slope, so that the formwork supporting efficiency is low, and meanwhile, the potential safety hazard is large. Meanwhile, bubbles in concrete generally rise in a straight line, but in the arc-shaped formwork, the bubbles are concentrated under the arc-shaped section, i.e., the arc-shaped concrete surface. Aiming at the situation, constructors usually can strengthen the vibration strength to eliminate the influence, but strong vibration can cause the surface of concrete to bleed, so that bubbles and the bubbles can be formed in the arc-shaped template, and a honeycomb pitted surface phenomenon is generated after the template is removed.
Therefore, in order to effectively solve the problems, it is particularly important to develop a construction method of a cast-in-place deep circular arc type wave wall which is convenient to install and dismantle, stable in structure, good in exhaust performance and capable of being recycled. Based on the background, the invention is developed and formed, and obvious economic and social benefits are certainly obtained when the invention is applied to the construction of the actual deep arc type wave wall.

step seven: dismantling a sliding type die carrier: after the first-segment deep arc wave wall (10) reaches the form removal strength, the split bolt (4) is removed, the hydraulic system is controlled to enable the hydraulic telescopic rod (106) to contract to the designated position, and then the deep arc wave wall (10) is subjected to film covering protection;
step eight: construction of the rear section wave wall: after the construction of the first-segment deep arc type wave wall (10) is completed, the plug pin (1053) is pulled out, the sliding type formwork is controlled to slide to the position of the rear-segment deep arc type wave wall (10) for construction, the fifth step to the seventh step are repeated until the subsequent construction of the segment deep arc type wave wall (10) is completed, and the sliding type formwork is removed for maintenance and standby.
