Technical Field
The utility model relates to a stable basic unit's construction field of highway road surface water, more specifically say, it relates to a stable basic unit's construction side form fixing device of road surface water of anchor angularly adjustable.
Background
In the construction of a highway pavement water-stable base course, the traditional construction method is that the edge part naturally slopes, and the design width needs to be increased during construction in order to ensure the compactness and the thickness of a structural layer; later, a template made of channel steel is provided, triangular supports are arranged at the backs of the channel steel, and the channel steel is driven into a roadbed to fix the triangular supports during use, so that the template is fixed. However, these processes have the following disadvantages:
the method has the advantages that the natural slope-releasing form is adopted, the edge part of the water-stable structure layer is free of a retaining structure, when the road roller rolls, the water-stable layer at the part can move outwards, the edge compactness of the water-stable layer is difficult to guarantee, after widening construction is adopted, although the thickness of the structure layer in the design width is guaranteed, the widened part also brings obvious cost increase.
The form that adopts the channel-section steel template to join in marriage the triangular supports scheme is used, and the marginal portion construction quality has very big promotion than adopting the mode of putting the slope. However, the construction method is limited by the limitation of the triangular support fixing mode, and the steel formwork can shift to different degrees during the operation of the road roller, so that the line shape of the edge of the base layer is irregular, and the structural layer thickness is still insufficient in the section with the large side shift of the formwork, so that the construction width of the base layer still needs to be increased properly during formwork erection.
When the template structure with the channel steel and the triangular supports is used for constructing the water-stable base layer with the number of layers of the second layer and above, the template is easy to displace when the road roller rolls due to the fact that the fixing mode of the triangular support structure is difficult to fix by the steel drill because of the influence of the steps formed by reducing the design width of the base layer by layer.
