Problems solved by technology

At present, the solar greenhouse wall structure mainly includes three types: earth wall, brick wall and composite wall. The earth wall has the advantages of good heat storage and heat preservation performance, low cost, easy to popularize, and fast construction speed. Short life, high maintenance and repair costs; brick wall has stable structure, convenient construction, small footprint, but its cost is high, heat preservation and heat storage performance is not as good as earth wall; composite wall is made of different wall materials and Composed of thermal insulation materials, its structural support is good, and its thermal insulation performance is better than that of brick walls, but the construction process is more complicated, the construction quality cannot be guaranteed, and the high cost is not conducive to popularization

Embodiment 1

[0031] A mountain energy-saving solar greenhouse wall, comprising a wall foundation 2 and a wall 1, the wall foundation 2 is located at the bottom of the wall 1, and the wall foundation 2 is wider than the bottom of the wall 1 by more than 300mm.

[0032] The wall 1 has a trapezoidal structure, and a plurality of geogrids 3 and anchor rods 4 are arranged in the wall, a consolidation layer 5 is arranged on the surface of the wall, and a steel wire mesh 6 and a cement mortar surface layer 7 are arranged outside the consolidation layer 5 , the steel wire mesh 6 is connected to the consolidation layer 5 and embedded in the cement mortar surface layer 7 . Steel mesh is fixed with U-shaped anchor bar 8.

[0033] Geogrid 3 is made of glass fiber geogrid, the grid size is 25.4×25.4mm, and the interval between multiple geogrids is 1 meter. Multi-layer geogrids are laid from bottom to top. When laying each layer of geogrids, adjacent pieces are lapped. The lap width is not less than 15...

Embodiment 2

[0046] Aiming at mountain conditions, multiple greenhouses are arranged in front and back. The consolidation material sprayed on the outside of the back wall of the greenhouse is W-OHC solution with a mass concentration of 10-15%. The penetration depth of the consolidation material solution into the wall is 5-8cm; steel wire mesh The strength of the cement mortar sprayed on the outer surface is not less than M5, and the thickness is greater than 10mm. Also mixed with quartz powder and cellulose ether in the cement mortar, according to parts by weight, for every 100 parts of cement, add 60-80 parts of quartz powder and 0.05-0.5 part of cellulose ether to enhance the strength and toughness of the cement mortar. The firmness of the outer side of the rear wall is enhanced.

Embodiment 3

[0048] For areas with many rodents, when making the wall foundation of the greenhouse, double-layer steel wire mesh is inserted longitudinally in the foundation, and the insertion depth of the steel mesh is more than 50 cm from the upper surface of the foundation to prevent rodents from damaging the greenhouse wall. And it can prevent the influence of mountain tree root growth on the greenhouse wall.

Abstract

The invention discloses a mountain energy-saving sunlight greenhouse wall and a manufacturing method thereof. The wall foundation comprises a wall foundation and a wall body, wherein the wall foundation is located at the bottom of the wall body, the wall body is of a trapezoidal structure, a plurality of geogrids and anchor rods are arranged in the wall body, a consolidation layer is arranged on the surface layer of the wall body, a steel wire mesh and a cement mortar surface layer are arranged outside the consolidation layer, and the steel wire mesh is connected with the consolidation layer and embedded in the cement mortar surface layer. Loess is tamped by a heavy hammer, so that the l bearing capacity of the loess is improved, and the loess collapsibility phenomenon is eliminated; and the surface of the wall body carries out consolidation material spraying, the steel wire mesh is hung, and cement mortar sprays the surface of the fixed steel wire mesh, so that by the method, the structural stability and strength of the loess can be improved, and the service life of the soil wall body is prolonged.

Description

technical field [0001] The invention discloses a mountainous energy-saving solar greenhouse wall and a manufacturing method thereof, belonging to the technical field of agricultural engineering greenhouse structures. Background technique [0002] The reduction of land resources has brought hidden dangers to the problem of food security. How to produce enough food and vegetables on the existing land is the problem we need to face now. Especially in the mountains, hills and plateaus, the planting conditions are poor, the traffic is relatively inconvenient, and the benefits are low, resulting in more and more mountainous lands being idle. The solar greenhouse is a unique type of greenhouse in northern my country. Its vegetable production has not only become an important way to solve the winter and spring vegetable supply in the northern region, but also promoted the increase of farmers' income, employment opportunities, and the development of other industries. [0003] The wal...
