the cement blanket structure layer comprises an upper lining layer and a lower lining layer which are connected through a connecting mechanism and have water permeability, and a forming layer structure which is filled between the upper lining layer and the lower lining layer and has water absorption and solidification properties;
the net cushion structure layer is composed of a cushion layer with water permeability and elasticity.
The additional technical characteristics of the novel lining pad also comprise:
the cement blanket structure layer is longer than the mesh pad structure layer to form a lap joint structure;
a grid filter cloth is arranged between an upper lining layer and a lower lining layer which form the cement blanket structure layer, and the grid filter cloth separates the upper lining layer and the lower lining layer into a plurality of grid structures which form a forming layer structure material for filling and forming the water absorption and solidification performance;
a water filtering cloth layer structure is arranged on the bottom surface of the mesh pad structure layer.
Compared with the prior art, the novel lining pad provided by the utility model has the following advantages: the lining pad is composed of a cement blanket structure layer and a mesh pad structure layer which is arranged on one side surface of the lining pad and is connected with the cement blanket structure layer into a whole, so that after the lining pad is laid on a side slope, the bottom of a ditch and a canal and a reservoir slope for irrigation, the cement blanket structure layer can form a solidified cement layer structure which is tightly attached to the slope bottom and has certain hardness, and the lining pad has the characteristics of convenience in construction, time saving, labor saving and environmental protection; meanwhile, as the bottom of the lining mat is provided with the cushion layer structure with water permeability and elasticity, the formation water in the side slope can be discharged through the cushion layer structure, so that the problem that the lining mat bulges due to underground water can be effectively prevented; secondly, the water filtering cloth layer structure is arranged on the bottom surface of the mesh pad structure layer, so that the blocking of the mesh pad caused by the soil impurities entering the mesh pad structure layer can be effectively prevented; thirdly, because the net cushion structure layer forming the lining cushion has elastic performance, the energy dissipation of frost heaving of side slopes forming a canal, a reservoir and the like can be realized, and the damage of the frost heaving to the lining cushion layer is effectively overcome.

in order to maintain the water permeability of the mesh pad structure layer 2 to the maximum extent and ensure that underground water can be concentrated to a discharge position through the structure, so as to prevent soil impurities from entering the structure, the water filtering cloth layer structure 22 is arranged on the bottom surface forming the mesh pad structure layer;
in consideration of the problem of the preparation process, a grid filter cloth 15 is arranged between the upper lining layer 11 and the lower lining layer 12 which form the cement blanket structure layer 1 (the grid filter cloth can be arranged in parallel with the connecting silk threads 13 which connect the upper geotechnical cloth layer 11 and the lower geotechnical cloth layer 12, or can be arranged independently which can replace the connecting silk threads 13 and has a cutting function), the grid filter cloth and the upper lining layer 11 and the lower lining layer 12 form a plurality of grid partitions together, and the grid partitions are used for filling a grid structure 16 which forms a forming layer structure material with water absorption and solidification properties, so that the loss of the powder material which is filled between the upper lining layer 11 and the lower lining layer 12 and is not solidified during transportation is avoided; the more the grid structure is, the more the lining wine formed by the grid structure is flat and regular; the preparation is carried out by filling each grid structure 16 with a powdered material of the forming layer structure through the upper liner 11.
