Description

Mould for building rammed earth wall

Technical Field

The utility model relates to the technical field of microalgae culture pond construction, in particular to a mould for constructing a rammed earth wall.

Background

The microalgae has the characteristics of high protein content, high growth speed, availability of non-cultivated land culture and the like, and a large amount of cultured microalgae can provide high-quality protein raw materials for food or feed. The agricultural microalgae are mostly cultivated in large tanks outdoors, and the cultivation tanks are usually rectangular with side lengths of tens of meters or hundreds of meters, and can be in other shapes. The traditional pond building materials are generally of a brick-concrete structure, and although the strength is high, a large amount of bricks and cement are consumed, and the transportation, construction and other operations of a large amount of building materials are involved in the pond building process. In addition, a large amount of construction waste is easy to form after the culture pond is scrapped, which is not beneficial to environmental protection and land protection.

The tools for constructing the traditional rammed earth wall mainly comprise wall screens, namely a mould, a ramming pestle, a log cross arm, a large clapping plate, a small clapping plate and the like. The mould is formed by splicing boards made of old fir, the outer part can be rough, but the inner surface is flat. The specification is generally 1.5-2m long, 40cm high and 7cm thick. One end of the rammed earth wall mould is open, and is supported by a wall clip made of hard miscellaneous wood to form an H shape, and the non-open end is fixed by a wall needle. The wall needle is two mold seals fixed by tenons, so that the mold can be flexibly disassembled. The ramming pestle rod is made of heavy and difficult-to-crack miscellaneous wood, and the weight of the ramming pestle rod is about 5-10kg. The two ends of the pestle rod are larger at one end and smaller at the other end, the diameter is about 8 cm to 10cm, and the middle part is cut to be suitable for holding. The big clapper and the small clapper are also made of miscellaneous woods, the length of the big clapper is about lm, the length of the small clapper is 20cm, and the width is about 7cm. The clapping plate has the function of clapping the wall skin on two sides of the wall, so that the wall skin is hard and solid. Compared with the brick-concrete structure, the rammed earth wall structure has the advantages that the main raw material is soil, the construction process is simple, the construction and construction costs are greatly reduced, more importantly, the rammed earth wall structure can be digested in situ after being abandoned, and the construction waste and the adverse effect on the environment can not be generated after returning to the land. If the rammed earth wall structure is applied to the construction of the microalgae culture pond, the construction cost can be effectively reduced, and the generation of construction waste and the adverse effect on the environment can be effectively avoided. However, when the traditional rammed earth wall mould is used, the wall screen is required to be frequently disassembled and assembled so as to realize rammed earth compaction and demoulding, so that the operation is complicated, and the tenon assembly strength is weakened after the wall screen is frequently disassembled and assembled for a period of time, so that the service life of the wall screen is influenced. In addition, the rammed earth wall building has a certain height (usually higher than one meter and several tens meters), so that the mould can be moved in the vertical direction, the rammed earth wall building is realized by applying the rammed earth wall building to different heights, the building height of the microalgae culture pond is very low, usually about 55cm, and the rammed earth wall building is only extended in the length direction and is not applied to different heights, and therefore, the problem that the operation is complicated and the service life is short when the traditional rammed earth wall mould is directly applied to the microalgae culture pond building is solved, and the problems of complex structure and low building efficiency are also solved.
