Background
A prefabricated panel reinforced earth retaining wall is a mainstream structural form in the reinforced earth retaining wall. The traditional panel structure adopts a method of grouting geogrid between panels to connect the panels and the geogrid, and the panel structure is influenced by factors such as grouting quality, upper panel weight, panel surface friction and the like, so that the effective connection between the panels and the geogrid is difficult to ensure. In recent years, with the application of a large number of reinforced retaining walls, the panel often falls off to cause engineering failure, and the panel becomes a common phenomenon of engineering accidents of the reinforced retaining wall. Therefore, constructing a panel structure that ensures effective connection of the panels to the geogrid has become a key technical problem of the reinforced earth retaining wall structure system.
Disclosure of Invention
The invention aims to provide a combined panel of a wrapped reinforced earth retaining wall, which aims to solve the technical problem of failure of engineering caused by easy falling of the panel in the prior art.
The invention adopts the following technical scheme to solve the problems, and the specific scheme is as follows.
A panel structure-a wrapped reinforced earth retaining wall combined panel which ensures the effective connection of the panel and the geogrid is adopted. The combined panel of the wrapped reinforced earth retaining wall comprises an upper panel, a lower panel and a middle panel which are connected in an embedded manner; the geogrid is wrapped around the middle panel to form a wrapped shape.
Preferably, the method comprises the following steps: the section of the upper panel is approximately inverted L-shaped, the top of the transverse limb of the upper panel is provided with a convex strip, and the lower part of the transverse limb of the upper panel is provided with a concave groove.
Preferably, the method comprises the following steps: the cross section of the lower panel is approximately L-shaped, and the upper part and the lower part of the transverse limb of the lower panel are both provided with concave grooves.
Preferably, the method comprises the following steps: the cross section of the middle panel is approximately in a transverse T shape, the upper part and the lower part of each longitudinal limb are provided with convex strips, the convex strips are provided with reinforced belt grooves according to the space of the geogrid, and the reinforced belts are strips forming the geogrid.
Preferably, the method comprises the following steps: the convex strips and the concave grooves which are contacted among the panels are in one-to-one correspondence in structural shape and size and are embedded with each other; gaps which are not less than the requirements of the thickness of the geogrid and the mortar thickness are reserved at the contact positions among the panels and are fixedly embedded and connected through the mortar of the convex strips and the concave grooves.
Further: geogrid is walked around middle panel through adding the muscle trough of belt, adds muscle trough of belt bottom and is arc distribution on middle panel, perhaps: the reinforced belt grooves are distributed along the middle panel in an arc shape, and the geogrid bypasses the middle panel along the reinforced belt grooves.
Further: the upper panel, the lower panel and the middle panel form a unit structure; when the inclined panel structure is implemented, the positions of the convex strips and the concave grooves on the lower panel and the upper panel among the unit structures are adjusted according to specific engineering requirements to form required panel back distances, and the lower panel of the upper-level unit structure is mutually embedded with the upper panel of the lower-level unit structure.
As another scheme: and non-embedded masonry is carried out between the upper and lower wrapping type reinforced earth retaining wall combined panel unit structures, and at the moment, the convex strips on the upper panel and the concave grooves at the lower part of the lower panel are omitted.
Advantageous effects
The geogrid is connected with the middle panel in a wrapping mode, so that the dependence of the traditional panel on factors such as the mortar quality, the upper part weight, the friction between the geogrid and the panel and the like is reduced or even eliminated, the connection reliability is greatly improved, and the failure of engineering caused by the falling of the panel is avoided; the geogrid is connected with the arc-shaped wrapping of the middle panel, so that the construction difficulty and the unreasonable stress state of large-angle turning of the geogrid of the traditional panel are avoided.
The continuous state that the joint of the geogrid and the panel does not slide or fall off is ensured, the geogrid is ensured to have small deformation and reliable force transmission at the panel, and the geogrid has great significance for slope stabilization and deformation control; the upper panel and the lower panel provide guarantee for the geogrid to prevent ultraviolet corrosion, physical damage and protection of the middle panel, and meanwhile, the appearance of the retaining wall is improved.
In addition, the invention can also be used for the implementation of the variable-slope-angle panel.
