Example (b):

as shown in fig. 1, the present application provides a reinforcing structure for three-dimensional reinforcement of a raw soil brick wall, including a reinforcing layer and a fixing member 5 for reinforcing the raw soil brick wall 1, wherein the fixing member 5 is vertically nailed into the reinforcing structure and the raw soil brick wall 1, and the reinforcing layer is sequentially provided with a first mortar layer 2, a net layer 3 and a second mortar layer 4 from inside to outside.

As shown in fig. 1 and 2, the fixing member 5 of the present embodiment is vertically nailed into the wall surface of the raw soil wall 1 to form a shear key, covering a first mortar layer 2 on the surface of the wall body to enable the fixing piece 5 to be bonded with the wall body, then covering a layer of net layer 3 made of net material on the surface of the first mortar layer 2, enabling the whole anchoring force of the fixing piece 5 to be totally concentrated on the wall body of the raw brick wall 1 by using the net layer 3, so that the stability of the raw brick wall 1 is improved, and finally, the second mortar layer 4 is covered on the net layer 3 to roughly level the wall surface, namely, a reinforcing layer is formed by the first mortar layer 2, the net layer 3 and the second mortar layer 4, namely, the capability of the fixed parts thereof to bear the force cooperatively is ensured by the bonding action between the reinforcing layer and the raw soil brick wall 1, so that the stability of the wall body of the raw soil brick masonry house is enhanced, and the reinforcing structure of the present embodiment does not require a fine treatment of the surface of the raw brick wall 1.

In yet another embodiment of this embodiment, the first and

second mortar layers

2 and 4 are both cement mortar layers. Because the raw soil brick wall 1 is piled up by soil, consequently when mounting 5 is nailed into the wall face perpendicularly, its clamping force is still in the state of lacking, consequently all set up the raw and other materials of first mortar layer 2 and second mortar layer 4 into cement, the cement mortar layer that forms through cement can be effectual bonds mounting 5 and stratum reticulare 3, further make the combination of mounting 5 and raw soil brick wall 1, the clamping force of mount and raw soil brick wall 1 has been increaseed, optionally can also replace cement mortar layer for soil mud layer, for example, loess mud, the viscidity of this kind of mud is great, can satisfy and consolidate required clamping force to the wall body.

In another embodiment of this embodiment, the number of the fixing members 5 on the reinforcing layer is several and is uniformly distributed on the reinforcing layer. Clear away earlier before the nailing of mounting 5 and wait to consolidate surface courses such as mud, cement slurry that raw soil brick brickwork wall body surface paintd, if the existing hole size degree of depth of raw soil brick brickwork wall is suitable, it can to select suitable position to clear up promptly, expose raw soil brick brickwork outward, for the fixity of better promotion raw soil brick wall 1, can go into raw soil brick wall 1 face with the even perpendicular nail of mounting 5, if can be according to the size of the existing hole on raw soil brick wall 1, come the even perpendicular nail of how to select better to go into raw soil brick wall 1 face.

In another embodiment of the present embodiment, the mesh layer 3 is any one of iron wire mesh, steel wire mesh, glass fiber mesh and woven mesh. Realize fixing mounting 5 through stratum reticulare 3, avoid mounting 1 to take place the slope, lead to the reinforcing effect to the immature soil brick wall to reduce, stratum reticulare 3 can adopt wire net, wire netting or the net that some metal material made all can, except foretell net, possess certain ductility net among the prior art also can.

In yet another embodiment of this embodiment, the depth of the fastener 5 driven into the raw brick wall 1 is greater than 10 mm. If no proper hole is formed in the surface of the raw soil brick wall 1, the fixing piece 5 is vertically nailed into the raw soil brick wall 1, but the structural property of the raw soil brick wall 1 is possibly damaged by directly nailing through external force in consideration of the soil property, so that holes with the depth of more than 10mm are drilled through a small drill bit, all the holes are required to be cleaned and ash is removed, water is sprayed for wetting, and a certain depth can be ensured to avoid violent shaking to enable the fixing piece 5 in the raw soil brick wall 1 to fall off and lose the reinforcing effect on the wall body when an earthquake occurs, different depths can be changed for different soil wall bodies, and the depth of the fixing piece 5 vertically nailed into the wall body can be properly adjusted according to the thickness of the raw soil brick wall 1, the local soil property viscosity and the like.

In yet another embodiment of this embodiment, the thickness of the reinforcement layer is 15-50 mm. Because the outer side of the raw brick wall 1 needs to be covered with a plurality of cement paste layers, and each layer has thickness, the fixing piece 5 on the outer layer also needs a certain length, so that the fixing piece 5, the mortar layer covered on the periphery of the fixing piece 5 and the net layer 3 can form an integral reinforcing layer, and the stability of the wall body is ensured.

In yet another embodiment of the present embodiment, the fixing member 5 is any one or more of a wooden pin, a bamboo pin, a steel bar, an expansion bolt, and a screw nail. Because the wooden pin and the bamboo pin are convenient to obtain, the wooden pin and the bamboo pin are thrown into the wall body, the subsequent dismantling is not difficult to recover, the native renewable reinforcing material is adopted, the environmental adaptability is good, the cost is low, and certain defects exist in the service life of the wooden pin and the bamboo pin. The screw-thread nail is a metal nail, the service life of the screw-thread nail is far longer than that of a wooden pin or a bamboo pin, but the subsequent recovery is inconvenient, and the screw-thread nail is not only provided with the wooden pin, the bamboo pin, a reinforcing steel bar, an expansion bolt and the screw-thread nail, but also provided with a rod-shaped article with certain shearing resistance in the prior art.

As a specific implementation mode: the method is characterized in that holes stripped or damaged on the existing raw soil brick masonry wall are utilized, bamboo pins, wood pins, expansion bolts or screw-thread shooting nails and other materials which are easy to obtain in the native state are inserted, and then a cement mortar layer covered on the surface is combined to form a three-dimensional space three-dimensional reinforcing structure; and using a native material as a shear bond; the two are combined, so that the interaction between the raw soil brick masonry wall and the reinforcing material is integrally promoted.

The concrete implementation is as follows: and clearing a slurry surface layer painted on the surface of the wall body of the raw soil brick masonry to be reinforced, and exposing the raw soil brick masonry outside.

And selecting a hole with a proper hole size and depth of the raw soil brick masonry wall to clean and remove ash, and spraying water to wet.

And inserting the wood pin/bamboo pin into the selected hole, wherein the insertion depth is more than 10mm, and the exposed length is 10 mm.

And pouring cement mortar, and thinly coating a layer of cement mortar with the thickness of 5mm, namely the first mortar layer 2, on the surface of the raw soil brick wall 1 to roughly level the wall surface.

The net layer 3 is fixed on an exposed wooden pin, a bamboo pin or a threaded shooting nail.

A layer of 15mm thick cement material, the second mortar layer 4, is applied to the mesh layer 3 and the mortar layer is smoothed with a cement palm.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
