Description
Technical Field
The utility model relates to a soil retaining structure based on round slide piles. The method is suitable for the fields of highway subgrade engineering, landslide control, related geotechnical engineering and the like.
Background
The anti-slide pile is widely applied to slope support and landslide control engineering by the huge bending resistance and shearing resistance. With the development of economic technology and the improvement of engineering construction safety standards, the manual hole digging rectangular pile is gradually replaced by the mechanical rotary digging circular anti-slide pile. When the anti-slide pile has a cantilever with a certain height, a soil retaining plate is needed to support soil between piles.
The manual hole digging rectangular pile can be used for installing the soil retaining plate behind the pile (digging side slope) in a manual grooving mode after pile forming, or installing the soil retaining plate layer by layer along with the construction of a filling body. However, the circular slide resistant piles are difficult to provide a plane required for the erection of the conventional soil guard plates due to the limitation of the sectional shape, and thus the soil guard plates cannot be effectively installed by the conventional method.
Currently, more installation and construction methods are used for retaining structures incorporating circular slide piles, including:
and (3) a bar planting method: drilling holes on the formed anti-slide pile body, implanting reinforcing steel bars, welding and fixedly connecting with the reinforcing steel bars of the soil retaining plates (placing the soil retaining plates between piles), or anchoring and connecting with the soil retaining plates (placing the soil retaining plates in front of piles). The method is easy to damage the main tendons of the slide-resistant pile, and the connecting points are stressed weak points and are damaged in the subsequent loading process;
the method for embedding the reinforcing steel bars comprises the following steps: after the anti-slide pile reinforcement cage is installed, embedding reinforcing steel bars at required points, pouring concrete, and welding or anchoring the retaining plate after pile forming. Although the method avoids damaging the longitudinal ribs, the round pile always adopts a steel pile casing to protect and stabilize the soil body of the hole opening in the hole forming process, so that the operation of embedding the reinforcing steel bars is limited;
the direct splicing method comprises the following steps: similar to a giant slide resistant pile, the retaining plate is positioned directly behind the pile. The method often causes the overlap area between the retaining plate and the slide-resistant piles to be too small, so that the retaining plate is displaced and even the retaining capacity is affected.
