Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, for the utility model discloses an off-load formula pile sheet barricade can be used in the system of strutting such as foundation ditch, bank protection to the foundation ditch barricade is exemplified, and off-load formula pile sheet barricade includes retaining pile 1, connects retaining plate 3 between two adjacent retaining piles 1 and sets firmly the off-load platform 2 behind retaining pile 1.
The retaining piles 1 are evenly arranged along the direction of the foundation pit at intervals. The retaining pile 1 is divided into an upper section and a lower section, wherein the upper section is a loading section 11 which is positioned above a substrate and mainly bears the soil pressure behind a wall; the lower section is the embedded section 12 below the substrate.
The retaining pile 1 can be of a reinforced concrete structure or a stiff steel structure, and the cross section of the retaining pile 1 can be rectangular, square, circular or in other shapes.
The unloading platform 2 is arranged on the back side of the loaded section 11 of the retaining pile 1 and comprises a bracket 22 and a platform plate 21, wherein the bracket 22 is fixedly arranged on the back side of the retaining pile 1 and is perpendicular to the retaining pile 1, and the bracket 22 can be connected with the retaining pile by bolts and is used for supporting the platform plate 21. The platform plate 21 is horizontally and fixedly installed on the upper surface of the bracket 22 and is used for bearing the load applied by the filler. The width and the burial depth of the unloading platform 2 are determined according to the requirements needed during construction and are not limited. The unloading platform 2 divides the retaining wall into two parts up and down, the part of the retaining wall above the unloading platform 2 is called an upper wall 5, and the part from the unloading platform 2 to the base is called a lower wall 6.
The top of the retaining pile 1 is provided with a top beam 4, the top beam 4 connects a plurality of retaining piles 1 into a whole, the top beam 4 can be a reinforced concrete continuous beam, the function of strengthening the integrity and the deformation coordination of the retaining wall is achieved, and collapse of the top edge of the foundation pit is prevented.
