Detailed ways

A kind of reinforced raw earth wall structure as shown in Fig. 1 and Fig. 2, comprises raw earth wall 1, and the first cement mortar layer 2 is all coated on the inner surface and the outer surface of described raw earth wall 1, The first cement mortar layer 2 is coated with a second cement mortar layer 3, and the second cement mortar layer 3 is embedded with a reinforcement mesh 4; the reinforcement mesh 4 includes a plurality of vertical strips 4-1 and a plurality of The horizontal strips 4-2, a plurality of the vertical strips 4-1 and a plurality of the horizontal strips 4-2 are arranged in a criss-cross pattern to form a plurality of connection nodes 4-3, and the vertical strips 4-1 and The horizontal slats 4-2 are bound and connected at the connection nodes 4-3, and a circle of connection nodes 4-3 on the reinforcement mesh 4 and near its edge are all connected to the first cement mortar layer 2 through anchors 6, so The anchors 6 pass through the first cement mortar layer 2 and extend into the raw soil wall 1, and the raw soil wall 1 is provided with a reinforcing mesh for placing the inside of the raw soil wall 1 4 and the cross-piercing steel bar 5 connected to the reinforcement net 4 located on the outside of the raw earth wall 1 .

In this embodiment, when the reinforcement mesh 4 is installed, the reinforcement mesh 4 is firmly connected to the first cement mortar layer 2 through the anchors 6, and then the positioning and installation of the reinforcement mesh 4 can be successfully completed.

In this embodiment, the vertical slats 4-1 and the horizontal slats 4-2 are connected at the connecting node 4-3 by ropes or iron wires.

In this embodiment, the vertical strip board 4-1 and the horizontal strip board 4-2 are both wooden boards. The local timber resources in rural areas can be fully utilized, and the wooden reinforcing net 4 has a relatively small self-weight, which reduces the pressure on the raw soil wall 1 .
