Description

A kind of slope film surface concrete formwork frame

Technical field

The utility model belongs to the field of slope construction, and particularly relates to a slope membrane surface concrete formwork frame.

Background technique

In concrete construction, formwork is a commonly used support construction method in concrete construction. Scaffolding is usually used as a support system on tall slopes. However, this support system will lead to slopes with anti-seepage requirements or slopes with membrane surfaces. The friction coefficient of the slope concrete becomes smaller. The supported system in this method needs to be connected to the scaffolding by means of slope anchors to carry the horizontal pressure of the scaffolding and the tension generated when pouring concrete. The anchors are anchored in the soil or rock of the slope and are connected to the scaffolding. The connection needs to pass through the membrane surface, destroying the anti-seepage surface or membrane surface, and failing to achieve the anti-seepage effect. Therefore, construction on tall slopes that require protection of the anti-seepage surface or membrane surface can easily damage the anti-seepage surface or membrane surface. If the integral formwork is used, the construction speed is slow and the cost is high.

The above-mentioned prior art has the disadvantages of easily damaging the anti-seepage surface or membrane surface, slow construction speed, and high cost. Therefore, in order to solve this defect, it is necessary to provide a tall slope membrane surface concrete formwork that does not need to rely on slope load-bearing support, can reduce process waiting time, is easy and fast to disassemble and install, and can reduce construction costs.
